The Experimental Study of Rural Domestic Sewage Treated with the Mixture of Diatomite and Coagulant

Abstract:

In this study, we treat rural domestic sewage with the mixture of diatomite and three kinds of coagulant. The result shows that with three mixtures, CODcr removal rate can be above 40%, and above 35% that of ammonia nitrogen. Compared with diatomite alone, the treatment effect has been significantly improved. We can come to a conclusion by the orthogonal experiment that the influencing factors on the effect of coagulant have following order: pH> dosage >stirring time, which means Ph plays an important role on the effect of coagulant.
