摘　　要：本文主要研究不同水力负荷条件下,波形潜流人工湿地对低浓度生活污水中有机物、氮和磷的去除效果及其影响因素。低、中、高水力负荷分别为0·2、0·4、0·8m3/(m2·d),处理低浓度生活污水试验研究表明:水力负荷对CODCr和TP的去除率有一定的影响,都是随着水力负荷的增大而下降;对NH3-N和TN的去除效果几乎没有影响。It was studied the removal effect of organisms,N and P in domestic wastewater by a corrugated underflow wetland subjected to different hydraulic loadings.The low,medium and high hydraulic loadings were 0.2 m^3/(m^2·d),0.4 m^3/(m^2·d) and 0.8 m^3/(m^2·d) respectively.The results showed that hydraulic loading had a certain effect on the removal rate of COD_ Cr and TP,i.e.the removal rate was decreased with increase in hydraulic loading;it almost had no effect on the removal rate of NH_3-N and TN.
