中文摘要：

以石佛寺人工湿地为研究背景，通过对湿地水质进行长期监测，来研究人工湿地对辽河水质的修复效果。结果表明：石佛寺表面流人工湿地对有机物、溶解氧与营养盐具有良好的修复效果。对CODMn、CODCr和BOD5的去除率最高可分别达到48．3％、66．5％和65．8％；部分时段湿地出口处DO比入口有所降低，但比建立人工湿地前DO浓度高，微生物对有机污染物的分解需要消耗溶解氧；在汛期对NH3-N、TN和TP的去除率最高可达78．1％、88．2％和72．0％。汛期出口水质基本达到Ⅲ类水质标准，符合《辽宁省水功能区划》石佛寺水库水质级别为Ⅲ类的要求。2012年水质状况良好，但部分去除率出现负值，说明要加强水生植物衰败后的管理，防止对水质的二次污染。

英文摘要：

This paper takes the Shifosi Constructed Wetland as a background through the long-term monitoring of the wetland water quality, to study the constructed wetland restoration effect of the Liaohe River water quality. The removal rate of CODMn, CODer and BOD5 can reach 48. 3%, 66.5% and 65.8%. Part-time wetland DO at the exit is lower than the entrance, but the concentration of DO is higher than the constructed wetland is not built, microbial decomposition of organic pollutants need the consumption of dissolved oxygen. The removal rate of NH3 --N, TN and TP can reach 78. 1%, 88. 2%and72.0% in flood season. The exit water quality basically reaches water quality standard of Grade Ⅲ, achieve the Liaoning Water Function Division standards of Grade Ⅲ on Shi fosi Reservoir water quality requirements. The water is of good quality in 2012, but part of removal rate appears negative, we should strengthen the management of decaying aquatic plants, to avoid its secondary pollution.
