Description

  The present invention relates to an improvement of a coagulation aid for purifying contaminated water that is dropped into contaminated water generated in a waste treatment plant or the like to agglomerate contaminants contained in the contaminated water to purify the water quality. The present invention relates to a new application technique of a method for producing a coagulation aid for purifying contaminated water as a main component.

  As a method for purifying contaminated water, there is a conventional method for coagulating and precipitating pollutants by the action of a flocculant. Examples of such conventional contaminated water purification techniques include Patent Document 1 and Patent Document 2, for example. What is shown is known. These conventional flocculants are mainly composed of polyaluminum chloride or aluminum sulfate. As other types, mixed flocculants obtained by mixing mineral powder with flocculants mainly composed of polyaluminum chloride or aluminum sulfate are often used.

  The coagulant used as a means for purifying contaminated water uses chemical substances (for example, polyaluminum chloride, aluminum sulfate, or calcium sulfate), and a method of coagulating and separating by the action of these chemical substances is a treatment method. Each time, it is necessary to separate the flocculant from the treated water and dispose of it. In recent years, food processing factories and the like have tried to reduce the disposal cost by squeezing fruits and vegetables with a pressing vegetable squeezing machine to reduce the amount of waste made of processed materials. In this case, solids after squeezing fruits, vegetables, etc. can be incinerated as waste, but the current situation is that they are struggling with processing of squeezed juice (liquid content), such as expensive septic tanks Purification of contaminated water by bacteria. However, even when such contaminated water is purified by bacteria, there is a problem that the processing speed of water purification is slow. In addition, floating particles containing alkali metals such as arsenic, mercury, and cesium cannot be simultaneously removed with a general flocculant.

  The present invention has been made in view of the above-mentioned problems. The purpose of the present invention is to use an auxiliary agent for purification of contaminated water, and to effectively purify the contaminants in agglomeration and precipitation, while at the time of each treatment.

On the other hand, when the transmittance T is 95 or less, the process proceeds to step ST20, color measurement is performed by the measurement CCD color area sensor, and it is checked whether the blue marker determination value C is smaller than 1 or not. When the determination value C is smaller than 1, the process proceeds to step ST22, which is the next processing step. On the other hand, when the blue marker determination value C is not smaller than 1, it is determined that the coagulant auxiliary agent is excessive and quantitative input is performed. After changing the number of times to K = K−1 (step ST21), the process proceeds to step ST22.
