刘芬芬 %A 王德建 %A 张刚 %J 环境工程学报 %D 2012 %I %X Seasonal performances of anaerobic tank-integrated constructed wetland(AT-ICW) system for rural domestic sewage treatment were investigated.Results showed that the system in spring,summer,autumn played a great role on the removal efficiency of ammonium(NH+4-N),total phosphorus(TP),and average removal rates were 92.8%~97.0% and 56.4%~65.9%,respectively,in contrast the removal efficiency in winter was a little low,and the average removal rates were 67.1% and 42.5%,respectively.The NO-3-N removal ability of the system was poor and appeared the accumulation with the average cumulative rate of 71.5%~342.9% during four seasons.The system could effectively reduce total nitrogen(TN) by 57.3%~68.9% in spring and summer and relatively low by 24.5%~35.8% in autumn and winter.The COD removal effect of the system in summer was good with the average removal rate of 78.3%,by contrast,winter and spring remove effect is poorer by 37.8%~43.5%.The effluent can meet Class A level one of national discharge standard of pollutant for municipal wastewater treatment plant.The AT-ICW system is not only effective on pollutant removal but also low cost of operation,so it is suitable for rural decentralized sewage treatment. %K integrated constructed wetland %K domestic sewage %K treatment effect %K seasonal variation
