摘要: 为有效地处理垃圾渗滤液这种污染物种类繁多的毒性废水,采用ICP-MS质谱仪对广州大田山垃圾渗滤液中的重金属进行分析,共测出46种金属元素,其中有10种被列入美国环保局优先控制污染物的黑名单.在这10种优先控制污染物中,铬、镍、锌、铜、铅的含量相对较高,其中铬、锌的含量甚至超过100 μg/L.采用同时好氧一厌氧生物反应器处理垃圾渗滤液,结果表明,有10种重金属的去除率超过70%,12种重金属的去除率在50%~69% 之间,浓度较高的铬、锌去除率均超过了60%.在所测出的lO种优先控制污染物中,铬、锌、砷、铅、硒的去除率均超过了60%.

Abstract:

In order to efi ciently treat landfill leachate,a sort of efluent containing complex pollutants,ICP -MS analysis was used to measure the heavy metals contained in the landfill leachate generated from Datianshan landrill in Guangzhou.46 kinds of heavy metals in the landfill leachate were detected,1 0 of which belong to the environ.mental priority pollutants considered by Environmental Protection Agency in USA. In these 1 0 priority pollutants,the mass concentrations of Cr,Ni,Zn,Cu and Pb are comparatively high,especially those of Cr and Zn.which are more than 1 00 μg/L. Moreover,a set of simultaneous aerobic.anaerobic bioreactor was used t()treat the landrill  leachate.The results demonstrate that 10 of the 46 pollutants have a removal rate of more than 70%, 12 of 50% ~69%,and the removal rates of Cr and Zn all exceed 60%.In addition, in the ten priority pollutants.the removal
rates of Cr,Zn,As,Pb and Se account for more than 60% .
