摘　　要：采用盆栽试验模拟潜流型人工湿地,研究了土壤、蛭石、煤渣和碎石四种人工湿地基质不同组合净化养猪场污水的能力。结果表明:以上层蛭石土混合物、下层煤渣和碎石的组合处理效果最佳,14d内COD_(Cr)、NH_4^+-N、T-P的去除率分别达到了95．3％、90％、91．6％。试验前期,四种不同组合基质的COD_(Cr)、NH_4^+-N、T-P去处率有明显差异,但试验后期除T-P的去除率仍有明显差异外,COD_(Cr)和NH_4^+-N去除率已无明显差异。The ability of pollution purification by four kinds of substrate materials(soil,vermiculite,cinder and detritus)in pots as simulated subsurface constructed wetlands was studied.The results showed that the removal rates of CODcr,NH4_+^+—N and T—P were 95.3%,90%,91.6% after 14 days,respectively.The best combina- tion of filtering media was soil and vermiculite at the up layer,the cinder and detritus at the low layer.In the fore- part of experiment,there were significant differences between the four different combinations in the removal rate of COD_(Cr),NH_4^+—N and T—P.However,in the later part of experiment the differences became not significant, except in the removal rate of T—P.
