摘要
针对水厂出现藻污染和嗅味问题,通过二氧化氯预氧化进行去除藻污染和嗅味的试验研究,结果表明:二氧化氯预氧化的投加量为1.0mg/L时,就可基本完全去除藻污染,并有效控制藻毒素的释放;能够显著增加浊度、色度、藻类和有机物的去除率;能够抑制藻类在平流沉淀池中的再生长;游离二氧化氯稳定持续地氧化积累在滤池中的藻类及胞内物质,有效地解决了滤后藻毒素及致嗅物质升高问题。二氧化氯预氧化可以作为应急除藻、解决嗅味问题的有效措施,有推广应用价值。
For removing algae pollution and odor smell in waterworks, the experiment by utilizing chlorine dioxide pre-oxidation proved that at the dose of 1. 0mg/L, the algae could be almost removed and the MC-LR could be effectively controlled ; the removal of color, turbidity, odor and organics could be greatly improved; reproduction of algae in flat sedimentation could be restrained. Owing to free chlorine dioxide keep oxidizing the algae and the materials in cell accumulated in the filter tank, the MC and odors could be effectively controlled at low grade. The technology of chlorine dioxide preoxidation should be a feasible treatment method for removing algae and odor in emergency and worth promoting in future.
