Chemical treatment of industrial wastewater
Add a certain chemical substance to sewage, and use chemical reaction to separate and recover pollutants in sewage.
Add a certain chemical substance to sewage, and use chemical reaction to separate and recover pollutants in sewage. Commonly used methods include chemical precipitation, coagulation, neutralization, oxidation reduction (including electrolysis), etc.
Chemical method can be used-polyaluminum chloride flocculant, as an inorganic polymer flocculant, through the mechanism of compression of electric double layer, adsorption and neutralization, adsorption bridging, sedimentation net complement and other mechanisms to remove fine suspended particles and colloids in water Stabilization, aggregation, flocculation, coagulation, and precipitation can achieve the purification treatment effect. Because of its wide pH value and good adaptability, it is widely used in industrial wastewater treatment.
