摘　　要：用生物接触氧化法预处理富营养化太湖原水的研究结果表明 ,该工艺可有效去除原水中 85 .9%的细胞外藻毒素和 84 .0 %的总藻毒素 ,对细胞外Microcystin RR(M RR)和Microcystin LR(M LR)的去除率分别为 81.7%和 86 .7% ,对总M RR和M LR的去除率分别为 80 .5 %和 71.5 % ,从而可大量节省常规工艺的加药、加氯量 ,减轻滤池工作负荷 ,提高出厂水的卫生安全性。Study was made on the use of biological contact oxidation process for pretreatment of eutrophic water in Taihu Lake. The result showed that the process can effectively remove 85.9% of extracellular microcystins and 84.0% of total microcystins from raw water. The removal rate of extracellular Microcystin-RR (M-RR) and Micrecystin-LR (M-LR) can reach 81.7% and 86.7% respectively; the removal rate of total M-RR and total M-LR is 80.5% and 71.5% respectively, and thus saving a lot of chemical and chlorine dosage, reducing the working load of filter, and improving the safety of finished water.
