摘　　要：分别以活性炭水凝胶、二氧化硅水凝胶为载体制作人工水草,研究了该新型人工水草对磁湖污水的原位处理效果。结果表明,二氧化硅水凝胶人工水草可显著改善水体透明度,对COD、TN、NH4+-N、TP的吸附速率快,吸附容量可达7.80 mgCOD/g、0.74 mgTN/g、0.29 mgNH4+-N/g、0.036 mgTP/g,其净化能力明显优于活性炭水凝胶人工水草。经汞灯照射后,2种水凝胶人工水草对各污染物的去除率均有较大的提高,且二氧化硅水凝胶人工水草的再生能力更优。因此,二氧化硅水凝胶人工水草可应用于磁湖污水的原位修复。Two new kinds of artificial plants made of activated carbon hydrogel （ called APACH hereafter） and silica hydrogel（ called APSH hereafter ） were used to treat polluted water of Cihu lake .The results showed that the APSH significantly improved water clarity and adsorption rate for COD ,TN,NH4 ＋-N,TP.The ad-sorption capacity of APSH were up to 7.80 mgCOD/g,0.74 mgTN/g,0.29 mgNH4 ＋-N/g,0.036 mgTP/g, respectively,which was obviously better than that of APACH .Irradiated by mercury lamp,two artificial plants both greatly enhanced pollutants removal efficiency ,while the APSH regenerated better .Therefore,the artifi-cial plant with silica hydrogel could be used for in -situ remediation of polluted water of Cihu lake .
