Where is the advantage of using polyaluminum chloride in cement industry wastewater treatment? Where is the advantage of using polyaluminum chloride in cement industry wastewater treatment? 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 body, it can cause siltation of the river channel, thus affecting people's normal daily life. . 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. Aimed at the characteristics of the wastewater from cement production, after full trial and demonstration, the wastewater treatment of cement industry uses polyaluminum chloride as the flocculant, compressing the electric double layer, reducing the Σ potential, and then adding a small amount of polyacrylamide as a coagulant, which is preferably used Cationic polyacrylamide. By virtue of its macromolecular adsorption bridging function, the detachment of fine particles into larger particles, increase the settlement rate, so as to achieve the goal of mud and water separation. The advantages of polyaluminum chloride used in cement industry wastewater treatment are as follows: 1. The flocs are formed rapidly and have high settling velocity and are more capable of processing than the traditional products such as aluminum sulfate. 2, consumption of water alkalinity lower than a variety of inorganic coagulant, which can not cast or less cast alkali. 3, to adapt to the source water PH5.0-9.0 range can be condensed. 4, corrosive, good operating conditions. 5, solubility better than aluminum sulfate. 6, the treatment of salt in the water increased less conducive to ion exchange treatment and high purity water. 7, Adaptability to source water temperature is better than inorganic coagulant such as aluminum sulfate. The use of Poly aluminum chloride coagulation and sedimentation process for cement production wastewater treatment and reuse is reasonable and feasible, it is worth learning from the relevant projects.
