摘　　要：投加低浓度H2O2可控制污水处理厂生物泡沫的产生,实验数据表明,投加低浓度H2O2能氧化部分生物残渣和消除生物代谢过程产生的毒素,并能改善菌胶团菌生活的微环境,促进菌胶团菌的生长。结果表明,在泡沫发生的敏感期间,预先投加低浓度的H2O2能较好地防止泡沫产生。Control of biological foaming by adding H2O2 in an activated sludge Sewage t reatment plant is introduced. The data show tha t adding low dosage of H2O2 is a ble to oxidize the toxin and residue of activated sludge. It can improve the liv ing environment of floc-forming bacteria and promote the normal growth velocity of f loc-forming bacteria.It is concluded that H2O2 addition can control the biol ogical foaming. 
