摘要: 构建阶式生物接触氧化反应器处理富营养化太湖水源水，对其净水效能进行研究。结果表明，在优化工况条件下，阶式生物氧化反应器的三阶对太湖水源水中DOC的累积去除率分别为34.4%、40.2%和47.5%，对BDOC的总去除率为68.4%，除生物降解外，填料拦截、生物吸附絮凝等物理、化学作用对去除原水中的DOC仍有重要作用。DOC分子量分级表明，太湖源水中含量最大的是分子量<500 Da的DOC，含量最小的是分子量在5 k~500 Da间的DOC。阶式生物接触氧化反应器对分子量<500 Da的DOC的去除率在60

Abstract: Cascade biological contact reactor(CBCR) was conducted to treat eutrophic Taihu Lake raw water，and the purification efficiency was studied. Results indicated that under optimized technological conditions，the three cascade of CBCR could get an accumulated removal rates of 34.4%，40.2%，47.5%，respectively to DOC，and 68.4% to BDOC. Filler interception，biofilm adsorption and bioflocculation also took an important role to DOC removal besides biological degradation. Distribution of DOC molecular weight(MW) showed that DOC with MW lower than 500 Dalton took the greatest part in Taihu Lake raw water，and DOC with MW between 5 k to 500 Dalton took the minimum part. The CBCR could remove DOC with low MW effectively.The removal rate of DOC with MW below 500 Dalton reached more than 60%.While the content of DOC with MW between 5 k to 500 Dalton doubled relative to raw warter.
