[Metho ] Base on ecological principles, ecological agro itch was esigne to apply in mo ifying the existe itches, enlarge its ecological cubage an make it have a higher removal efficiencies of pollutants in sewage water in Liangjia village on the northern lakeshore of Dianchi Lake. An its purifying effect was monitore an evaluate . [ Result] The average removal rates of TN, TP an COD by ecological itch with extrinsicmi croorganism were 70. 3%, 66. 6%, 73. 7% , respectively, correspon ingvalues were 48. 3%, 60. 6%, 58.0% respectively for ecological itches without extrinsic microorganism, an 30. 1%, 23. 8% an 18. 4% for the existe itch. [ Conclusion] The ecological agro itch not only ha a significant purify effect of sewage, also cost little a itional lan , coul be promote .
