塘西河人工湿地对再生水厂出水水质净化效果研究

Study on the Effect of Tangxihe Wetland Purification Recycled Water

为研究人工湿地对塘西河再生水厂排放水的净化效果,对湿地进出水水质进行监测。结果发现,湿地对水中的磷酸盐、硝酸盐均具有一定的净化效果,A区、B区磷酸盐、硝酸盐平均去除率分别为27.3%、40.93%和35.99%、41.47%。对于磷酸盐,B区去除效果要好于A区,这主要是B区配置有几种植物的结果;对于硝酸盐,A、B区净化效果无太大差异,说明植物配置还需要进一步优化。

To study the purification effect of artificial wetland on Tangxihe recycling plant drainage,the wetland water quality is monitored in this paper,and the result shows that wetland has some purification effect on phosphate and nitrate in water,the average removal rates of phosphate and nitrate at A area,B area are 27. 3%,40. 93% and 35. 99%,41. 47%,respectively. For phosphate,the removal rate at B area is higher than that at A area,this is mainly because that B area has several plants but A area has not. For nitrate,the purification effect has no too much difference at A,B area,this suggests that wetland plant need to be further optimized.
