摘要
研究了高锰酸钾复合药剂(PPC)预氧化与预氯化联用对含颤藻水样及由其引起嗅味的混凝处理效果,并与单纯预氯化、高锰酸钾预氧化、复合药剂预氧化、高锰酸钾预氧化与预氯化联用以及单纯混凝的处理效果进行了对比。结果表明,单纯混凝及单纯高锰酸钾预氧化对颤藻及其引起的嗅味去除效果很差;单纯预氯化及高锰酸钾预氧化与预氯化联用除藻效果尚可,但对嗅味不仅未去除反而有所增强;而PPC预氧化及其与预氯化联用除藻、除嗅味效果均较好,采用PPC预氧化与预氯化联用方式处理效果更佳。
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.
