蚯蚓生态滤池对农村生活污水的深度净化效果
Study of earthworm ecology filter for rural sewage purification
摘要
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.关键词
