There is. Therefore, construction regulations (water quality regulation value, etc.) tend to be tightened year by year. In order to reduce the concentration of this polluted water to below the water quality regulation value, for example, a sedimentation pond was constructed on the downstream side of the construction site, and the polluted water mixed with the coagulant was flowed into the sedimentation pond from the inflow part of the sedimentation pond. Was there. By mixing this coagulant into polluted water,
Soil particles aggregate and settle in the sedimentation basin due to chemical reaction,
The filtered water is discharged from the outflow section of the settling basin. But,
If this coagulant is mixed into polluted water, the soil particles can be coagulated and settled, but since the coagulant is mixed in the water after this treatment, this coagulant must be removed. .
