    Automatic analysis, monitoring and control system of temperature, moisture and oxygen in aerobic composting basin in aerobic composting tank
    [14] The present invention can automatically continuously measure the temperature, moisture content and oxygen in the aerobic composting tank which ferments high concentration organic waste in aerobic state to produce compost, and can monitor the measured data in real time and automatically control the driving equipment based on this. The present invention relates to a continuous automatic monitoring and control system.
    [15] Recycling methods of food waste mainly used in Korea include aerobic composting, sewage sludge treatment, dry and wet feed, among which are used for stabilization of organic wastes such as livestock manure as well as silk food waste. Aerobic composting is the most widely used method.
    [16] The aerobic composting method is a method of decomposing and stabilizing organic substances contained in organic waste by using microorganisms. An important factor is control of proper water content in the pretreatment stage, sufficient air supply and adequate agitation in the fermentation stage. .
    [17] Most of the aerobic composting facilities applied in Korea are failing to control water due to excessive air supply and rely mainly on empirical operation technology due to agitation of one or two times a day. Because of the very primitive level of measurement equipment for important factors such as water, moisture content, and oxygen, and the measurement method is one-off, it is difficult to continuously measure it, and thus its utility value is not fully exhibited.
    [18] In the case of existing aerobic composting facilities, samples were collected from composting tanks and analyzed in order to measure temperature and moisture content in the composting tanks. For sampling purposes, the risk of direct exposure to odors and harmful gases from composting tanks cannot be ruled out. In addition, in order to measure moisture content and oxygen concentration, expensive equipment is required, and even if the equipment is equipped, it is necessary to secure a professional manpower to operate the equipment. As a result of adoption, most installations will only be able to intermittently analyze or even not analyze only when necessary.
    [19] Unlike water treatment, aerobic composting, which has recently been in the limelight, requires additional processing and management to interpret the measured data. In addition, it is recognized that it is almost impossible to monitor remotely from the control room. As a result, they have not been able to effectively utilize the data secured, and have accumulated little or no data necessary for the operation secured over the years. Therefore, most facilities have to operate their facilities based on short experiences, and many fail.
    [20] On the other hand, in order to reflect the aerobic fermenter operation using the measured data, it is necessary to set some environmental factors, among which the most easy to control the air flow rate and the number of stirring times. Until now, these factors were passively controlled based on experience. Failure to control the airflow and agitation frequency may result in the production of waste, as organic material is not fully decomposed and thus loses its value as compost. Therefore, the accumulation of necessary data and know-how in the operation of aerobic composting facilities is important above all, and it is possible to optimize the composting facilities only when the facility is operated based on this.
    [21] Therefore, in the present invention, in the facility for composting various high-concentration organic wastes including food waste aerobics continuously by automatically measuring and monitoring the temperature, moisture content and oxygen concentration in the composting tank by controlling the air supply blower and fermentation stirrer based on this Its purpose is to provide a system that can be integratedly managed from the monitoring stage to the control stage.
    [22] An object of the present invention is to provide a module and a communication system which can continuously measure automatically in the data measurement step, thereby protecting the driver from harmful gases and enabling efficient data acquisition. In the monitoring phase, the received data is sorted and processed by factor, and the graphic processing is performed in a state necessary for operation.In addition, the web monitoring function is applied to accelerate the operation of the facility. By making it possible, the response to emergencies can be made more quickly and effectively.
    [23] In the present invention, it is possible to automatically control the air volume and the number of stirring using the data measured above, which can not only reduce the manpower and power costs required for the operation of aerobic composting facilities, but also changes the environmental conditions in the composting tank. It is aimed to maintain optimum fermentation state by appropriate response operation according to
    [24] The present invention for achieving the above object is a continuous automatic measurement and monitoring of temperature, water content, oxygen in the aerobic composting tank characterized in that the support module is installed in the fermentation stirrer installed in the aerobic composting tank to attach the measurement module By providing a control device.
