摘要
采用一种新型湿地系统装置对农村生活污水进行处理,总实验周期170 d,每个采样周期为7 d,采样频次5次,针对湿地系统及污水COD、NH_4^+-N、TP等指标进行测定。实验结果表明,湿地系统在经过45 d的启动期后可正式进入使用阶段,并在5月与6月对生活污水的处理效果为最佳。同时还发现温度和水中的溶解氧含量均为影响湿地系统去除COD、NH_4^+-N、TP的关键因素。
In this paper,a new wetland system was used to treat rural sewage.The total experimental period is170d,each sampling period is7continuous days and the sampling frequency is5times.The indexes,such as COD,NH4+-N and TP of wetland system and sewage were measured.The experimental results show that the wetland system can enter the operation stage after the start-up period of45d,and the treatment effect on domestic sewage is the best in May and June.We also found that the temperature and the dissolved oxygen content in water are the key factors that affect the removal of COD,NH4+-N and TP in wetland system.
