垂直流人工湿地对景区污水磷的处理效果分析

Study on Scenic Domestic Wastewater Treatment for Phosphate in a Vertical Flow Constructed Wetland

对浙江舟山朱家尖垂直流人工湿地的磷酸盐净化效果进行了分析。结果表明,人工湿地在2011年3月～12月运行的10个月中,对污水中磷酸盐的去除率平均为32.22%±5.80%(平均值±SE),要比人工湿地运行的前两年(即2007～2008年)显著低得多,但出水水质基本达到城镇污水处理厂污染物排放标准Ⅲ类水质标准值(GB 18918-2002)。

The cleaning efficiency of wastewater of the operated vertical flow constructed wetland in Zhujiajian in Zhoushan city of Zhejiang Province and the problems in the treatment system were discussed and analyzed in the paper.Results suggested that from March 2011 to December 2011,the main pollutants of phosphate was removed at a rate of 32.22 %±5.80 %（mean ± SE）,which was lower than that in 2007 and 2008,i.e.,the first and second year after carried out the constructed wetland.However,the water quality in the year achieved the standard Ⅲ of the discharge standard of pollutants of municipal wastewater treatment plant（GB 18918-2002）.
