Polyaluminum chloride phosphorus removal effect and coagulation is related to the pH value? Polyaluminum chloride phosphorus removal effect and coagulation is related to the pH value? With the growth of China's chemical industry, similar performance purifying agent is also coming out in strength, are based on the original purifying agent developed new products, take polyaluminium chloride, is based on the polymerization of chlorinated Iron and basic aluminum chloride basic performance upgrade developed, then what they have the same application performance? What is the improvement of the new product development effect? The following will be filtered by the source of water with everyone to understand. Inorganic flocculant polyaluminum chloride added to the water, the hydrolysis of polycore polycations, the role of the process can be combined with hydrogen phosphate, hydrogen phosphate and the occurrence of coordination reaction, the formation of a complex structure of macromolecular complexes , Reducing its water solubility, making it more agglomeration and coagulation settlement. At the same time, a large amount of hydroxide flocs formed in the coagulation process of PAC are precipitated and have strong adsorption capacity, and the phosphorus concentration in the wastewater can be reduced by floc adsorption. Therefore, it can be considered that the mechanism by which polyaluminum chloride can remove phosphorous from wastewater is mainly coordinated settlement and floc adsorption, which is consistent with the phenomenon that the removal rate increases with the dosage of coagulant. At the same time through the net catch and mechanical roll sweep mutual cohesion, eventually settling down, so as to achieve the purpose of coagulation phosphorus removal. Polyaluminum chloride removal effect is closely related to the coagulation pH, and the best phosphorus removal efficiency is obtained under the condition of pH 5.0 ~ 8.2. Its main mechanism of action with coordination sedimentation, floc adsorption, netting and mechanical roll sweep and so on. Polyaluminum chloride-containing flocs flocculation performance is better phosphorus in the dilution process is not easy to re-release of phosphorus. Compared with the two aluminum salts, the polyaluminum chloride-containing flocs flocculated slightly better than the polymerized ferric sulfate and crystalline aluminum trichloride. Therefore, the study on the mechanism of phosphorus removal, improve understanding of the mechanism of coagulant phosphorus removal has obvious practical significance.
