摘要
用下行流人工湿地处理生活污水,分析了系统对CODCr、TP、TN的处理效果,并将有无植物2种系统对污染物的去除效果进行对比。研究结果表明,下行流人工湿地对有机物、氮、磷都有很高的去除率;进水中TN和TP的浓度变化对出水中氮磷含量影响不大,系统对氮磷有一定的抗冲击能力;植物在污染物去除过程中起了重要的作用。
Down - flow constructed wetland is used to treat the sanitary wastewater. The removal rates of CODcr, TN and TP in the system are analyzed. The removal rates of pollu ＇tants in the two systems with and without plants are contrasted. It is found that the system can effectively remove CODc. TN and TP; the concentrations of TN and TP in the inflow almost doesn＇t affect the outflow and the plants react on the removal process of pollutants.
