    description
    Field of the Invention The present invention relates to an arrangement for automatic real-time analysis of an organic contaminant in water, by means of which the generation of a high concentration of a harmful organic contaminant can be rapidly and accurately accomplished by the real-time, continuous removal of a sample even using an existing analyzer recognized and thus appropriate countermeasure in a water treatment plant, etc. can be taken.
    Background Art Due to industrialization and urbanization, environmental pollution has long been a social problem, while at the same time systematic controls of drinking water qualities, such as water quality, are also being addressed. Protection of the drinking water supply source, management and regulation of the equipment for leakage of the contaminant, etc., in the national context become strict. A basis for these controls is a fast and accurate measurement of the contaminants in the water. Since rapid water quality measurement in potable water sources, purified water and tap water, etc., can provide a quick water purification process, it is even more important in the face of safety.
    The organic pollutants managed by the water supply system include dozens of types of substances, e.g. Volatile organic compounds, agrochemicals, disinfection by-products, as well as tasting and malodorous substances, etc. Since these organic pollutants have detrimental effects on human health or directly affect the quality of the tap water by causing an aesthetic problem, then such pollutants are required each fully and completely manage. Recently, the tasting and malodorous substances (geosmin, 2-MIB [methylisoborneol]) have increasingly been increased by such pollutants in their concentration and production frequency entering the water treatment plant, because the algal bloom has increased due to climatic changes such as climate change. Water temperature rises and precipitation pattern changes etc. are always causing more and more. Therefore, the fabrics must be prepared by employing a water purifying material, e.g. powdered activated carbon, etc., in the water treatment plant and thus by taking the quick countermeasures are treated to less than an odor threshold before they can be incorporated into a water supply network, so that customer complaints can be avoided. Therefore, the more complete administration is required.
    In the present water treatment plants, the tasting and malodorous substances in the normal state are analyzed once or less per day and only when the high concentration thereof is generated twice a day manually, but it is not easy at present to manually measure a constantly changing quality of water and thus take a countermeasure to the rapid water purification process. It is necessary, the volatile organic compounds and the agrochemicals, which arise both in the emergency situations, such as leaks in chemical plants, rollover accidents of chemical tankers transported in the water supply network, and the disinfection by-products, which arise only in small quantities, but in the water purification process, however, only manual measurement can be performed, which makes it difficult to combat such contaminants by rapid detection.
    In order to solve these problems, efforts have been made so far to monitor the quality of the water in real time.
    For example, various technologies for real-time monitoring of water quality are proposed by the following South Korean Fte registration patents:
    Ftegistrierungspatent no. KR 10-0 901 779 (2.6.2009) entitled "Internet-based monitoring and control system for measuring a water quality", registration patent no. KR 10-0 522 764 (Oct. 12, 2005) entitled "Device for real-time monitoring of a water quality and method for controlling the same», Registration Patent no. KR 10-1 406 884 (5.6.2014) entitled "Multi-wavelength analysis based on-line system for measuring water quality for the purpose of real-time detection of organic pollutants in water", and Registration Patent No. KR 10-1 253 251 (4.4.2013) entitled "Apparatus and method for real-time monitoring and control of substances causing taste and smell for the purpose of water purification".
    But most of the above patents relate to the prior art measurement of the fundamental quantities of water quality (eg, water temperature, pH, turbidity, electrical conductivity of a residual chlorine, etc.) or the total index sizes of organic materials (eg, total organic carbon [TOC], chemical oxygen demand [COD], etc.), some of which relate to the process of real-time measurement of certain organic contaminants. However, in these patents, methods other than existing analyzers or combining the various expensive equipments with each other are used, thus resulting in a drawback that precision, reliability and economy are reduced, and operation and management are hampered.
    As mentioned above, the organic contaminants in the water, e.g. tasting and malodorous substances, etc. are further analyzed more frequently. However, registration patents describe the combination of separate expensive equipment with each other, which is uneconomical and difficult to operate and manage. As a widely used apparatus for analyzing an organic pollutant in water, an analyzer consisting of a solid-phase microextraction device and a gas chromatography-mass spectrometry analyzer is currently being used extensively, but the utilization efficiency of this analyzer is too low and new devices have to be rebuilt, which therefore leads to uncomfortable problems.

    Here, in a section connected to a position of the sample supply line 42 in which the analyst wishes to check the quality of the water, there may be additionally arranged a pump 42b which can demand the fluid (the sample). In addition, at the end of the sample supply line, there is additionally arranged a washing pipe (not shown in the figure) which can supply to the sample bottle 30 washing water for washing the inside thereof, or the end connected to a portion to which the washing water is supplied, so that washing water the sampler can be supplied.
    On the other hand, it is configured such that a water discharge pipe 50 is connected to the above sample supply pipe 42 so that a new sample for sample supply pipe can always be provided.
    At this time, the water drainage pipe 50 is formed to branch from the sample supply pipe 42, i. it is arranged between a position in which the water quality should be checked and the sample supply valve 42a arranged in the sample supply line 42, but it is more preferable that it is located directly in front of the sample supply valve 42a.
    In contrast, the arrangement according to the invention is designed in such a way that, in order to allow the quantitative analysis, it has a constituent which can be filled with a certain amount of the sample to be supplied to the above sample bottle 30.
    For this purpose, the sample bottle 30 a sample supply amount Ftegeleinheit 34 which is adapted to record by means of the receptacle 31, the specific amount of sample, wherein the sample supply amount Ftegeleinheit 34 is disposed on a side surface of the sample bottle 30. However, it is advantageously provided that the sample supply amount-Ftegeleinheit is disposed at a precise height at which the receptacle 31 can be completely filled with the sample, so that only the specific quantity of sample in the receptacle 31 can be accommodated.
    Further, it may be additionally provided that a sample supply amount supply line 60 has a sample supply amount control valve 61 which connects the sample supply amount supply line with the sample supply amount fixing unit 34 formed in the sample bottle 30.
    In this case, it can be advantageously provided that the above-mentioned valves, like a solenoid valve, are so electronically controlled that they can be opened or closed by the control of a control unit C.
    Hereinafter, preferred embodiments of the arrangement for automatic real-time analysis of an organic pollutant in the water according to the present invention having the above-mentioned embodiments will be described in more detail.
    First, the automatic real-time analysis of an organic pollutant in water according to the present invention represents that which, with unchanged use of the previously used analyzer 10, can automatically analyze the organic pollutants in the water in real-time, and must be in locations or laboratories etc. within the appropriate test zones of the water quality be set to the test water, such as treated water, steam and processed water used in a water treatment plant, such as e.g. Water treatment plant arises to check its water quality.
    Thereafter, the test water is provided to this sample bottle in real time via the sample supply line 42 formed in the sample supply and discharge unit 40, which is connected to the sample supply 32 of the sample bottle 30.
    In this case, the feed operation, by means of which the test water is supplied via the sample supply line 42 of the sample bottle 30, such that the conventional control unit C opens the arranged in the sample supply line 42 sample supply Ftegelventil 42 a, so that the test water can be provided to the sample bottle, As shown in FIG. 5, a sample discharge valve 43a is disposed on a sample discharge line 43 disposed in the sample supply and discharge unit 40 connected to the sample discharge 33 of the sample bottle 30, and a drainage valve 51 of a water discharge line connected to the sample supply line 42 50 are controlled in a closed state, so that the receptacle 31 of the sample bottle 30 is filled with the sample as a test water.
    In this case, it is possible for the sample provided via the sample supply line 42 to be provided by means of a conventional pump 42a or to be moved by a water pressure arising from the purified water or hot water.
    In this way, the amount of sample filled in the sample bottle 30 reaches a certain quantity, i. a position on which the sample supply amount fixing unit 34 of the sample bottle 30 is formed, then the excessive sample provided via the sample supply amount feeding line 60 connected to the sample supply amount unit 34 is discharged outside, so that only the certain quantity of sample in the sample 31 is filled.
    When the predetermined quantity of sample is filled in this way, the sample supply pipe valve 42a disposed in the sample supply pipe 42 and the sample supply amount valve 61 arranged in the sample supply amount pipe 60 are closed by the control unit C and thus the intake 31 is separated from outside within the sample tray 30, as shown in FIG. 6, so that sampling (concentration / extraction) can be performed by the analyzer 10 and analysis work, while the sample constantly supplied via the sample supply line 42 can be opened by opening the water removal Ftegelventils 51 of the water discharge line 50 can be discharged via this water discharge line 50.
    In this case, an effect can be achieved by means of the water discharge line 50, that the existing in the sample supply line 42 sample can be left only by the time to be provided in real time quantity.
    I. E. It was an object of the present invention to recognize, by analyzing the sample fed in real time, at what point in time the organic contaminants within the sample are superfluous, as explained above. Therefore, the above water discharge pipe 50 has been introduced, thereby acting in such a manner that the sample existing in the sample supply pipe 42 can be maintained only by the quantity to be actually provided and thus analyzed in real time.
    Thereafter, a needle of the solid phase micro extractor 11 for concentrating / extracting the sample is positioned in a head space inside the sample bottle 30.
    On the other hand, the heating block 20 accommodating the above sample bottle 30 is heated to the temperature suitable for the analysis (depending on the size of the analysis) and, if necessary, the guiding means 24 is operated so that the organic contaminants are removed from the receptacle 31 of the sample bottle 30 Sample in the headspace within the sample bottle 30 can move well.
    Thereafter, the solid phase micro extractor 11 is operated and the sample of the sample bottle 30 thus absorbed, so that this sample is then inserted into the gas chromatography mass spectrometry analyzer 12 and thus the analysis work of the same.
    Of course, during the process of performing the work by the analyzer 10, the constant provision of the sample to the sample bottle 30 is performed by means of the components as mentioned above. If the analysis work by the analyzer 10 is completed, then the sample taken in the other sample bottle 30 can be subsequently analyzed consecutively.
    On the other hand, the sample of the sample bottle 30 from which the analyzer 10 has taken out the sample to be analyzed is opened by opening the sample discharge valve 43a of the sample discharge line 43 connected to the sample discharge 33 formed in the sample bottle 30, and the Sample supply amount Ftegelventils 61 of the sample supply amount Ftegelleitung 60 discharged to the outside, as shown in Fig. 7, then the new sample again provided on the sample supply line 42 and thus removed the first remaining in the receptacle 31 of the sample bottle 30 sample ailes on the sample discharge line 43 is so that thereafter, in a state in which the Probenabfuhr-Ftegelventil 43 a is closed, the Probenzufuhrmenge-Ftegelventil 61 of the sample supply-quantity Ftegleitung 60 is closed. In this way, therefore, the procedures for picking up and analyzing the sample can be repeatedly performed.
    Since the sample provided thereby via the sample supply line 42 of the sample supply and discharge unit 40 is the one provided in real time, the real-time sampling and the sample analysis are sequentially performed by the analyzer 10, so that a concentration-time increase time point the organic pollutants can be recognized quickly and also the constant analysis can be made possible.
    In contrast, several sample bottles 30 according to the present invention may be formed on the heating block 20. In this case, only the sample of any position can be taken, but the one, connected to any sample bottle 30 sample supply and removal unit 40 is arranged in the processed water, while the other, connected to the other sample bottle 30 sample supply and removal unit 40 in Ftohwasser is arranged, etc., so that in different positions, the sample analyzes can be carried out simultaneously by the analyzer.
    In addition, according to the invention it is designed such that the above sample bottle 30 is formed in a size between about 100 and 150 ml in terms of capacity, so that a sufficient amount of organic contaminant may be included therein, the temperature being maintained by the heating means 22 and the temperature sensor 23 of the heating block 20 and the extraction (concentration / extraction) of the sample by the guide means 24 can be effectively performed, thus also providing an advantage that a sufficient degree of analysis sensitivity in the sample analysis by the analyzer 10 without Operation for employing the separate reaction chemicals can be obtained.
    In particular, if the analysis of the sample is a process for the automatic real-time analysis of the tasting and malodorous substances of the sample, then the arrangement according to the invention has an advantage that in addition to the chemical analysis by the analyzer 10 also a sensory analysis work can be carried out in parallel that the human being himself intends to test the sample and thus analyzes it.
    In the sensory analysis, since the degree of analysis sensitivity is reduced by the sensation of smell at the low temperature, the sample is heated, and then the analysis is performed through many preparatory operations. However, according to the present invention, by introducing the heating block 20, the sensory analysis work is readily carried out, so that an effect can be achieved that enables the constant real-time analysis as well as the analysis time can be shortened.
    As mentioned above, with the present invention, it may be provided that by incorporating the separate equipment in the analyzer, the existing equipment will be used unaltered, providing the sample in real time on an ongoing basis, thus providing a time at which an event occurs, is quickly detected, so that rapid countermeasure can be taken, and the present invention can be easily applied to the existing analyzer 10 at the same time, so that it is not necessary to introduce new equipment, which consequently can lead to the achievement of an economically very useful effect.
    It should be noted that the above-mentioned embodiments describe only one advantageous embodiment of the present invention, and therefore the present invention is not limited thereto, but rather changed in various forms within a scope that does not depart from the technical spirit of the invention and can be executed.
