酸雨对城市生活垃圾填埋场渗滤液性质的影响

Study on the leaching of pollutants from municipal refuses

取台州市新鲜生活垃圾作模拟酸雨淋溶试验,探讨在pH为4.0的模拟酸雨作用下垃圾溶出液中CODcr、油、重金属Cu、Zn、Ph、Ni、Hg等随降水时间及降水量的溶出情况,同时以pH为6.7为对照。在不同淋溶介质条件下,主要污染因子的淋溶释放一般符合Ct=C0tb模型。

By laboratory leaching experiments, under the acid rain effect with pH=4. 0 the leaching of CODcr,oil,Cu.Zn, Pb,Ni and Hg from municipal refuses from Taizhou were discussed, and the control was pH=6.7. The leachation of main pollutants generally accords with equation under great majority conditions:Ct=Cotb.
