石家庄市西北湿地公园对生活污水的处理效果研究

Study on the Treatment Effect of Domestic Sewage in Shijiazhuang Northwest Wetland Park

通过2016年1月—10月份对比监测西北湿地公园人工湿地系统中进、出水的主要水质指标,化学需氧量(COD)、氨氮、总磷(P)、总氮,结果表明该人工湿地对生活污水有很好的净化作用。其中,COD、氨氮、总磷、总氮的平均去除效率分别达到了64.75%、63.62%、86.8%、74.54%,表明人工湿地系统对污水的净化起到了很好的作用。说明利用人工湿地系统去除城市生活污水中的污染物的可行性,处理方法符合目前水环境生态保护要求。

The main water quality indicators of the incoming and outgoing water(COD,ammonia nitrogen,total phosphorus,total nitrogen)in the wetland system of northwest wetland park were monitored from January to October in2016.The results showed that the constructed wetland had a good effect on the domestic sewage.The average removal efficiency of COD,ammonia nitrogen,total phosphorus and total nitrogen were64.75%,63.62%,86.8%and74.54%,respectively.The artificial wetland system has played a very good role in the purification of sewage.It shows the feasibility of using artificial wetland system to remove pollutants from municipal sewage,and the treatment method is in accordance with the current water environment ecological protection trend.
