in cement industry wastewater treatment? What is the advantage of using poly aluminum chloride in cement industry wastewater treatment? Our country is a country that is relatively poor in water resources. Due to its large area, daily drinking water in some places can not normally be satisfied at times. This requires us to be recycled in the daily industrial waste water to achieve the purpose of saving water, pollute the industrial use of polyaluminum chloride can be reused, or in line with national emission standards. It is mainly used for rotary kiln cooling, ground flushing and rinsing mills. If it is not treated and directly discharged into the surface water bodies, it can cause the siltation of the river channel, thus affecting the daily life of ordinary people. . To deal with this water quality mainly by adding coagulant, such as polyaluminum chloride, polyaluminum chloride, aluminum chloride, polyacrylamide, etc., through the coagulant hydrolyzate compression chamber diffusion layer to reach the colloid Detached and cohesive with each other; or strongly adsorbed bridging action of the polymer formed by the hydrolysis and polycondensation reaction of the coagulant, so that the cavity particles are adsorbed and adhered. According to the characteristics of the wastewater from cement production, after sufficient test and demonstration, the wastewater treatment of cement industry uses polyaluminum chloride as the flocculant to compress the electric double layer, reduce the Σ potential, and then add a small amount of polyacrylamide as a coagulant, which is best used Cationic polyacrylamide. By its macromolecular adsorption bridging function. Will destabilize the small particles coalescence into larger particles, increase the settlement rate, so as to achieve the goal of mud and water separation. Poly aluminum chloride (PAC)
