摘　　要：生物激活剂促进污染水体的自净取得了良好的修复效果。投加量为1mg／L时,COD、NH3-N的最终去除率比空白对照分别提高了21.3％、38.4％,密闭条件下投加3mg／L生物激活剂后,水样中的溶解氧有所提高;水样初始pH在6.5-10.0时COD去除效果明显;漕河泾、青春河、颐景园、文化园四个不同水质水体的修复效果差别明显,COD的最终去除率分别为40.3％、11.7％、1.5％、39.6％,NH3-N的最终去除率分别为31.9％、27.0％、58.5％、85.4％。Remediation of the self-purification accelerated by bio-stimulant for polluted waters had been achieved. Ultimate removal rates of COD and ammonia-nitrogen (NH3-N) increased by 21. 3% and 38. 4%, respectively than those of blank after adding 1mg/L bio-stimulant. Dissolved oxygen had increased after adding 3mg/L bio-stimulant than that of blank under the condition of seal. After adding bio-stimulant,removal of COD was obvious within 6. 5-10. 0 of initial pH values. Remediation results of four waters with different water qualities was different remarkably, and ultimate removal rates of COD were 40. 3%、 11. 7% 、1. 5%、39. 6% ,respectively and those of NH3-N were 31. 9% 、27. 0%、,58. 5% 、85. 4% ,espectively.
