Polyaluminum in the sewage treatment coagulation mechanism depends on what factors? Polyaluminum in the sewage treatment coagulation mechanism depends on what factors? Filter water purification on coagulant in water treatment has done a lot of thought, polyaluminium coagulant in the treatment of domestic water, but also can be used as sewage treatment. Then polyaluminum chloride in the sewage treatment in what kind of coagulation mechanism, the following will be explained by the filter Li workers to explain the coagulation mechanism of polyaluminum chloride. In the treatment of polluted source water by polyaluminum chloride, the morphology distribution directly affects the coagulation and algae removal, turbidity removal efficiency, and residual aluminum concentration in the coagulation effluent. In the coagulation process, different forms of aluminum and iron hydrolysis process, and the role of particulate matter is different. Aluminum-iron medium polymers first interact with the particulate matter by means of adsorption neutralization, and then the molecular weight gradually increases under the effect of hydroxyl linking, finally forming a macro-flocs, during which some of the particles enter the flocs. Medium polymers in aqueous solution in a certain period of time to maintain its shape does not continue the stability of hydrolysis, thereby slowing the hydrolysis process, which makes medium-sized polymers have the full opportunity to absorb the role of particulate matter and electricity, and play bridge and network Catching and other mechanisms of action, it algae removal, turbidity efficiency higher, the formation of floc large, difficult to remain in the water. Therefore, it is the most advantageous component of decontamination. The monomer components in the coagulation process hydrolysis speed, and the formation of small size gel material, and its ability to form macro flocs is also lower than the medium polymer, easy to remain in the water, so that the coagulation precipitation of residual aluminum Increased concentration. Monomer composition mainly by compression double, floc adsorption removal of particulate matter, so its algae removal, turbidity removal efficiency. Therefore, the control of the hydrolysis process in the coagulation process to improve the coagulation effect is very favorable. Inorganic polymer coagulant is through the prepolymerization to control the hydrolysis process of coagulation. In the winter low temperature coagulation, hydrolysis is very slow, hydrolysis can be controlled by catalytic hydrolysis components, in order to improve the coagulation and decontamination efficiency, reduce residual aluminum concentration. In the conventional coagulation process, by adding other coagulants to reduce the monomer content in the coagulation process, increase the polymer content, in order to improve the coagulation efficiency and reduce residual aluminum concentration. For example, adding 20% ​​(silica to metal mole ratio) of activated silicic acid to algae coagulated with polyaluminum chloride not only increases the algaecide removal efficiency but also reduces the amount of residual aluminum in the coagulated effluent by 10% Quality Score). The reason for this is that the oxygen atoms of the polymeric silicates complex with the hydrogen atoms of the monomers or oligomers in the water to reduce the concentration of Ma; or to polymerize the silicate bridged monomer hydrolysates, thereby reducing the residual aluminum concentration in the water.
