Research Progress on Poly Silicate Aluminium Ferric Flocculant
摘要
Abstract
Polysilicate aluminum ferrite flocculant represents superior performance of sewage treatment. Reported in the literatures, as a new type of polymer inorganic flocculant, polysilicate aluminum ferrite flocculant shows great abilities of removing sewage turbidity, color and COD.The preparation method of poly aluminum silicate flocculant, flocculation process exist in the main mechanism of action and treatment effect are mainly described.The preparation methods include: compound method, copolymerization method, acid solution neutralization method.The mechanism of flocculation process includes the theory of compressive double layer, the role of adsorption and neutralization, adsorption bridging, net catching effect, synergistic action in a variety of mechanisms in the flocculation process, and then for water treatment better than other flocculants.The main influencing factors are Al /Fe /Si molar ratio, flocculant dosage, flocculant pH value and so on.Finally, the problems existing in the current research are briefly described.In the end, the paper pointed out the prospect and developing trends of Polysilicate aluminum ferrite flocculant.关键词
