Embodiment Construction
[0012] The present invention will be described in detail below in conjunction with the examples.
[0013] The sewage treatment agent is configured by the following parts by weight ratio, and is characterized in that: polyaluminum chloride 23; polyacrylamide 23; polyethyleneimine 10; bentonite 25.
[0014] The relative density of the polyferric trichloride is 1.450, acidic and easily soluble in water. Compared with the serious harm caused by aluminum salt flocculant residual aluminum to the human body and the biological toxicity of aluminum, as well as the poor coagulation effect and poor product stability of iron salt flocculant, this chemical composition has a wide range of applicable pH values. After treatment, the pH of the water does not decrease much, the chroma of the water does not increase, and the treatment effect is excellent. The effect is more pronounced when the treated water temperature is lower.
