摘　　要：采用水解酸化-二段生物接触氧化及水生植物进行截污试验,研究了水力停留时间(HRT)、容积负荷、水生植物等对生活污水截污效果的影响。结果表明:当HRT为6 h时,水解酸化-二段生物接触氧化对COD、NH+4-N和TP的平均去除率分别为77.6%、60.52%、53.37%;COD、NH+4-N和TP的最佳容积负荷率分别为216,11.57,1.52 g/(m3·h);加入凤眼莲后(HRT=4 h),NH+4-N、TP去除率分别可达81.39%及53.78%,比加植物前分别提高28.94%及10%,出水水质达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级B排放标准。The paper employed hydrolysis acidification-two stage bio-contact oxidation and hydrophyte to research the pollutants intercept of sewage. The influence of hydraulic retention time（ HRT）,volume load,aquatic plants on the treatment efficiency was studied. The results indicated that the mean removal ratios of COD,NH4^＋- N,TP were 77. 6%,60. 52%,53. 37% respectively while HRT = 6 h,and the optimal volumetric loading rates were 216,11. 575,1. 52 g /（ m^3·h）respectively. The NH4^＋- N,TP removal ratios reached 81. 39% and 53. 78%,increasing 28. 94% and 10% than before,respectively,while the system ran with Eichhornia crassipes involved under HRT = 4 h. The effluent quality could reach the＂Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant＂GB 18918—2002 1B.
