Study on Pre-oxidation and Enhanced Coagulation for Removal of Oscill atoria and Deodorization

Study was made on the treatment effect of algae-la den water and incu rred odor by using permanganate potassium composite (PPC) pre-oxidation in combi nation with pre-chlorination. Comparison was made on the treatment effect of the simple pre-chlorination; composite chemicals pre-oxidation, permanganate potass ium pre-oxidation, permanganate potassium pre-oxidation in combination with pre- chlorination, and simple coagulation. The results showed that simple coagulation and simple permanganate potassium pre-oxidation have less effect on removal of algae and its odor, simple pre-chlorination and permanganate potassium pre-oxida tion in combination with pre-chlorination have some effect on algae removal, how ever they not only fail to deodorize but also increase the odor; and PPC pre-oxi dation in combination with pre-chlorination has good effect both on algae remova l and deodorization. 
