| 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〈500Da的DOC，含量最小的是分子量在5k～500Da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％以上，而出水中5k～500 Da区间的DOC含量相比原水增加近1倍。 |

| 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... |
