Abstract：Three sewage treatment groups were set as microorganism group (Ⅰ) , plant group (Ⅱ) and plant synergistic with microorganism group (Ⅲ) .The concentrations of total nitrogen ( TN) , total phosphorus (TP) and chemical oxygen demand ( COD) were detected on the 4th, 8th, 12th and 16th day after treat-ments .The data were treated by SPSS .The results showed that the three treatment groups all reduced the con-centrations of TN , TP and COD significantly , which indicated that they all had good effects on treating sew-age .The group of plant synergistic with microorganism had the best effect .It could decrease the concentration of TN from 21.5607 mg/L to 5.2704 mg/L, TP from 6.1695 mg/L to 0.8279 mg/L and COD from 215.3 mg/L to 52.8 mg/L.
