| 摘 要： | 从生态学理论出发,以健全人工湿地生态系统为思路,通过引入爱胜蚯蚓使食物链"加环",强化水生动物环节,得出该工艺在0.3m3(/m·2d)的水力负荷下稳定运行后,处理农村生活污水的COD、TN和TP平均出水浓度分别为41.02mg/L、12.58mg/L和0.44mg/L,出水水质均低于国家城镇污水处理厂排放标准(GB18918-2002)一级排放A标准。同时蚯蚓对改善湿地内部溶解氧状况起到了一定的作用。 |

| Abstract: | Based on the ecology theory, the improved wetland ecosystem was studied, with addition of Eisenia foetida to the food chain and strengthening of link of aquatic animals. It concludedthat Eisenia foetida can improve the condition of DO in wetland. Under hydraulic load of 0.3m~3/(m~2·d), averageeffluent concentration of COD, TN and TP were 41.02mg/L, 12.58mg/L and 0.44mg/L respectively, with the effluent waterquality satisfactory to discharge standard for urban wastewater treatment plant of Grade I of GB18918-2002. |
