在冬季低温环境下,通过保温措施和未保温湿地系统进行对比实验,对COD、NH3-N、TN等主要污染物和人工湿地出水水温的跟踪监测,检验了保温措施的效果.实验结果表明:在冬季,使用芦苇秸秆+薄膜保温措施的处理系统中,COD、TN、NH3-N的去除率分别为49.1％、54.8％和49.9％,均高于未保温系统出水污染物去除率.利用芦苇秸秆+薄膜保温的人工湿地出水水温高于未保温系统3～4℃,证明了芦苇秸秆+薄膜有效提高了人工湿地内的温度.“,”Through insulation measures and uninsulated wetland system,in the winter low temperature environment.comparison tests on three main pollutants and the water temperature were conducted among two different insulation measures.The test results indicate that COD,TN and NH3-Nremoval rate was 49.1％,54.8％ and 49.9％,respectively,based on reed stalks and thin-film method of insulation measures processing system.These removal rates were higher than uninsulated wetland system.Using reed straw and film insulation heat preservation system of artificial wetland,water temperature was higher approximately 3～4 ℃ than uninsulated wetland system,which proved that reed stalks and thin-film method has ability to improve artificial wetland efficiency.
