摘　　要：以大型饮用水源生态净化工程为研究对象,分析了该工程不同季节、不同HRT下人工介质对微污染原水的净化效果。结果表明,人工介质对COD_(Mn)、NH_3-N、TN、TP和SS的平均去除率分别为7.2%、38.2%、16.8%、24.4%和34.4%,且去除效果随HRT的增加而有所增强;人工介质对污染物的去除效果因季节而异,COD_(Mn)各季节平均去除率表现为夏季>春季>秋季>冬季,对NH_3-N和TN各季节平均去除率表现为夏季>秋季>春季>冬季,对TP和SS各季节平均去除率均表现为冬季>秋季>夏季>春季。In a large ecological purification of drinking water source project as the research object, the effect of seasons and hydraulic retention time on purification of the slightly polluted raw water purification was investigated. The results show that, the average removal rate of artificial medium to CODMn, NH3 - N, TN, TP and SS were 7.2%, 38.2%,16.8%, 24.4% and 34.4%, respectively. And removal efficiency increased with the increase of the hydraulic retention time; Artificial medium on pollutants removal effect owing to the different season, average removal rate of CODMn in each season followed the order of summer 〉 spring 〉 autumn 〉 winter; average removal rate performance of NH3-N and TN follow the order of summer 〉 autumn 〉 spring 〉 winter; Each season average removal rate of TP and SS are shown as winter 〉 autumn 〉 summer 〉 spring.
