摘　　要：在实验室内,建立两种人工岸坡,研究不同水力负荷对岸坡地表径流净化效果的影响。结果显示,在不同水力负荷下,两种岸坡对径流中氨氮、高锰酸盐指数均具有较高的净化效率(NH_(3)-N 85%以上、COD_(Mn)90%以上);随着水力负荷的不断增加,两种岸坡对氨氮、高锰酸盐指数的净化效率均逐渐下降。其中,氨氮受水力负荷影响较大,净化效率下降明显;高锰酸盐指数净化效率则无明显差异,缓坡对氨氮的净化效率略高于陡坡。相比较而言,缓坡对氨氮、高锰酸盐指数的净化效率比陡坡更稳定。Two artificial bank slopes established in the laboratory were used to study the effects of different hydraulic loads on the surface runoff purification effect of the bank slope.The results show that,under different hydraulic loads,both bank slopes have high purification efficiency for NH_(3)-N and COD_(Mn)(NH_(3)-N is more than 85%,and COD_(Mn)is more than 90%);with the increasing hydraulic load,the purification efficiency of NH_(3)-N and COD_(Mn)gradually decreases.NH_(3)-N is greatly affected by hydraulic load,and the purification efficiency decreases significantly.There is no significant difference in the purification efficiency of COD_(Mn)on both slopes.The purification efficiency of NH_(3)-N on gentle slope is slightly higher than that on steep slope.In comparison,the purification efficiency of NH_(3)-N and COD_(Mn)on gentle slope is more stable than on steep slope.
