Coagulation of Granite particle using Jade particle}
[1] The present invention relates to a method for agglomeration of waste gangue residues in an economical and environmentally friendly manner utilizing waste resources. Specifically, it is to agglomerate the waste granite generated in the granite processing process without using a coagulant widely used in the conventional chemical method, and to solve the problem of environmental pollution generated when the supernatant is discharged. In order to achieve the above object, by mixing and stirring jade residue and water generated in jade processing process to waste sludge containing granite residue, the granite waste residue is coagulated and precipitated, and the supernatant purified by sedimentation is drained to the bottom. It is a technique to remove the sludge.
[2] Waste residues generated from the treatment of rock waste can be developed for many purposes, but due to their different surface electrical properties, they must be chemically treated to aggregate. In general, the flocculation efficiency is increased in an alkaline atmosphere, so the flocculation conditions should be alkaline in order to flocculate the generated waste residue. At this time, provision should be made to prevent water pollution caused by alkaline materials used.
[3] Such chemical treatment is suitable for the purpose of improving the flocculation efficiency, but a lot of contamination occurs due to the use of flocculation aids such as the physical properties of the flocculant used and the control of alkali, which is the optimum flocculation condition. Therefore, there is a problem that the secondary environmental pollution caused by the contamination of the supernatant generated by this and the resulting discharge water. As an alternative to solve this problem, in the present invention, to agglomerate the waste generated in the jade processing process to agglomerate the granite residue without affecting the properties of the supernatant.
[4] In order to solve the problems described above, the present invention intends to solidify liquid granules by agglomerating the granite suspended matter using the jade waste residue generated in the jade processing process, which is widely used as a health supplement. Waste residue from the processing of granite is a material that can be recycled for various purposes depending on the size of the residue. In general, waste residues that are discharged as wastes are sorted by a certain size after being sorted through a screening process and used for different purposes. At this time, it is common to work while spraying water to suppress the by-products generated by the fine particles generated in the shredding process. Therefore, after crushing, the fine particles meet with water to form sludge. Since flocculant must be used to treat the sludge thus produced, it may cause environmental pollution by the discharged water discharged after treatment.
[5] In addition, recently, because jade is used a lot as a health supplement, there are many problems in the treatment of ox sludge generated at this time. In order to solve this problem, in the present invention, by treating the granite residues using the debris residues generated in the jade processing process, it is determined that the problem of secondary environmental pollution can be solved, so as to process the granite sludge using the debris residues.
[6] In order to achieve the above object, the present invention aggregates the granite waste residue sludge using solid waste residue to separate solid / liquid. The treatment process is characterized in that the granite waste residue is dispersed in an aqueous solution and then the waste jade residue is added to aggregate the granite waste residue.
[7] Hereinafter, an Example is given and this invention is demonstrated in detail.
[8] <Example 1>
[9] First, in order to measure the basic physical properties in the aqueous solution of waste residues from granite processing, 0-30 g of waste residues were dispersed in 200 ml of water, and then pH, TDS, and conductivity were measured.
[10] The results are shown in Table 1.
[11] Waste residue (g)pHTDS (mg / l)Conductivity (μS) 07.0925.1 57.33818.1 107.531431.2 207.692043.8 307.931431.2
[12] As a result, after dispersing in aqueous solution, pH ranges from 7.33 to 7.93, total dissolved solids (TDS) concentration ranges from 8 to 20 mg / l, and the conductivity of aqueous solution ranges from 18 μS to 43.8 μS. The values up to were shown.
[13] <Example 2>
[14] In order to examine the effect of jadeite waste residue on the coagulation efficiency of granite using water as a dispersion medium, the sedimentability was measured by mixing the ratio of jadeite residue to granite in a weight ratio of 30: 0 to 0:30. Is shown in Table 2.
[15] Granite residue (g)Jade residue (g)Packing density (g / cm3) 5 minutes10 minutes20 minutes30 minutes40 minutes50 minutes60 minutes 300NMNMNMNMNMNMNM 2820.961.21.251.251.251.251.25 2640.680.830.920.981.031.031.03 2460.650.790.870.940.950.970.98 2280.510.670.740.80.830.860.88 20120.60.650.730.810.820.840.86 10200.480.50.540.570.580.590.59 0300.40.420.430.440.450.450.45
[16] According to the results, when 30 g of the granite residue was dispersed in an aqueous solution, the sedimentability was poor to the extent that the packing density could not be measured (NM). In addition, the sedimentation of jade residue itself is superior to that of granite itself, but not so good. However, in the case of mixing jade residues in a certain ratio with respect to granite, the sedimentability shows the best value when jade residues are added in an amount of 6.7 wt% to 13 wt%.
[17] <Example 3>
[18] Water was used as a dispersion medium, and the mixed waste stone residue and granite residue were mixed and shaken for 1 hour at a rotational speed of 320 rpm. After 120 minutes, the turbidity and other physical properties of the supernatant were measured and the results of the flocculation were tested. Table 3 shows.
[19] Granite residue (g)Jade residue (g)Properties of the Supernatant Turbidity (NTU)Conductivity (μS)TDS (mg / l)Sulfuric acid consumption (ml) 03012187.1880.6 301013.52371260.65 30209.472601240.7 30308.872881360.7 300390.6201951.0
[20] When 30 g of granite residue is dispersed in an aqueous solution, sulfuric acid consumption used to measure alkalinity of the supernatant is maximized, and sulfuric acid consumption tends to gradually decrease when oxane is added. The smallest alkalinity is found to be the smallest. This tendency shows a similar trend in turbidity and conductivity. Among them, the best result was obtained when the weight ratio of oxane was 25% by weight.
[21] Particularly, the turbidity of the supernatant when the 30 g of granite residue was dispersed in water was very high at 390.6 NTU, but the turbidity of the supernatant was 8.87 when 30 to 50 wt% of jade residue was added to 30 g of the granite residue by weight. From NTU to 13.5NTU, it shows a reduction efficiency of about 98%, indicating that the effect is very good.
[22] From the above results, when the granite suspended matter is treated by using the waste jade residue generated in the jade processing process, the treatment efficiency is excellent and the alkalinity of the supernatant liquid is remarkably reduced, so that it can be treated by an environmentally friendly method. Therefore, by utilizing these technologies, sludge generated from the recycling process of inorganic waste including construction waste can be treated in an environmentally friendly manner, and it will be possible to prevent contamination of water resources including groundwater and river water.
