Abstract：In this study,the fly ash zeolitic enhanced sand biofilter project was carried out for rural domestic wastewater treatment for one year.The results showed that the mean removal rate of chemical oxygen demand (COD),ammonia nitrogen (NH4+-N),total nitrogen (TN) and total phosphorus (TP) of domestic wastewater was 96.08％,93.24％,83.71％ and 88.82％,respectively.Their average value of effluent was 15.29,2.02,5.74 and 0.34 mg/L respectively,which met the first grade A standard of Cities Sewage Treatment Plant Pollutant Discharged Standard.Numbers of insulation measures were used in this project,and the temperature of influent and effluent were both above 10℃,so it could operate normally in winter.The running cost of the project was low,which was only 0.30 yuan per ton water for one day.
