摘要: 本实验利用多级蚯蚓生态滤池对农村生活污水进行处理研究，分别考察了不同季节蚯蚓生态滤池对COD、TN、NH+4-N和TP的去除效果，同时利用PCR-DGGE技术对不同季节的微生物群落进行初步分析。结果表明，夏季COD、TN、NH+4-N和TP的平均去除率分别达到86.05%、89.02%、98.48%和99.1%；出水浓度17.86、4.96、0.605和0.047 mg/L。冬季COD、TN、NH+4-N和TP的平均去除率分别达到83.29%、93.26%、96.96%和92.7%；出水浓度22.68、2.63、1.02和0.37 mg/L。不同季节出水水质均达到了《城镇污水处理厂污染物排放标准》（GB18918-2002）一级A类标准。蚯蚓生态滤池内的微生物多样性冬季的要比夏季的丰富，且冬季滤池内微生物种类从上至下逐渐增加，符合污染物去除效率的变化。

Abstract: In this study， multi-stage earthworm ecology filter was used for sewage treatment in rural areas. The removal efficiencies of COD，TN，NH+4-N，TP and analyst microbial communities by PCR-DGGE in different seasons were investigated. The results showed that removal efficiencies(COD，TN，NH+4-N and TP) reached 86.05%，89.02%，98.48% and 99.1% in summer and 83.29%，93.26%，96.96% and 92.7% in winter. The effluent concentrations of COD，TN，NH+4-N and TP were 17.86 mg/L，4.96 mg/L，0.605 mg/L，0.047 mg/L and 22.68 mg/L，2.63 mg/L，1.02 mg/L and 0.37 mg/L in the two different seasons， which met the need of “Urban Sewage Treatment Plant Pollutant Discharge Standard” (GB18918-2002) Class A. Microbial diversity in winter was richer than that in summer and species increased gradually from top to bottom， because of the same change of pollutant removal efficiency.
