摘　　要：应用高效微生物光合细菌、硝化细菌、复合细菌降解水中污染物。在投菌量100mg/L、第15天时对CODMn、浊度、NH3-N的去除率已达50%以上,能够使水中DO值由0.5mg/L左右提高到4.2mg/L左右,叶绿素a含量显著降低,该方法简单易行,运行成本较低。Some high effective microbes, photosynthetic bacteria, nitrifying bacteria,and corn-pound bacteria etc. were used,to degrade pollutants of water. The result of the experiment showed that CODM,. NH3-N. NTU removal rate reaches 50% and DO content arised from 0.5 to 4.2 mg/L and Chl-a is very low. Moreover,Using this method to treat polluted water is convenient and the cost is low.
