2种典型预氧化工艺对混凝去除假鱼腥藻及其代谢嗅味物质2-MIB的影响机制
Effect of two typical pre-oxidation processes on removal of preudanabaena sp. and its metabolites 2-MIB during coagulation
摘要
Abstract
With preudanabaena sp., the common algae in raw water, as research object, the removal efficiency of preudanabaena sp. and the metabolized odor and taste compound, 2-MIB was studied by using Al3+coagula-tion. The results show that the optimal dosage of Al3+is 3 mg/L. Meanwhile, pre-oxidation with potassium per-manganate and sodium hypochlorite were applied in order to enhance the coagulation. It is observed that low concentrations of potassium permanganate has no significant effect on coagulation while the peroxidation ex-hibits negative impact on the coagulation when MnO4-is increased to 2 mg/L, and the pre-oxidation with sodi-um hypochlorite even leads to the release of intracellular 2-MIB. Three-dimensional fluorescence data indi-cates that pre-oxidation process leads the release of intracellular organisms by cell lysis, which will have ef-fect on the coagulation.关键词
