摘要
对已发生污泥膨胀的系统中投加Ｈ２Ｏ２，通过研究系统中污泥的ＳＶ、ＳＶＩ及ＣＯＤ去除率的变化，发现Ｈ２Ｏ２能明显控制丝状菌，６０ｍｇ／Ｌ为其最佳投加浓度，进行了连续进样研究，并与ＮаＣＩＯ，聚铝，ＦｅＣｌ３三种药剂对污泥膨胀的作用进行了技术经济对比．
The method which this paper used is adding depressors including dydrogen peroxides, sodium, hypochlorite, PAC and ferric choride to the bulking system. Sludge volume index and removal efficiency for COD are examined to determine the best concentration of the four depressors, and the effect of the four depressors is continously observed for 24 hours.
