摘要
对大通采空塌陷天然湿地修复示范区处理化工垃圾渗滤液进行追踪研究,分析讨论了示范区内生物塘对垃圾渗滤液中COD、TN、TP、重金属、氯苯类化合物等污染物的去除效果。结果表明,生物塘对垃圾渗滤液中污染物的去除效果较佳,COD的去除率达到52.3%,BOD5/COD从0.08提高到0.17,TN、TP出水含量可达GB8978-1996中I类水标准,Cd、Cr、Cu、Ni这4种重金属的去除率在43.8%～100%,而对Pb的去除效果不明显,对氯苯类化合物去除率在80%～100%。
In this paper,the author has made a longitudinal study of the treatment of waste leachate by biological pond system in Datong District and tried to analyze and discuss the removal effect of pollutants such as COD,TN,TP,heavy metals and chlorobenzene compounds in water. The study showed that the removal effect was obvious except Pb,with the removal rate of COD reaching 52.3% and BOD5/COD values ranging from 0.08 to 0.17; the effluent concentration of TN and TP reached Rank I of GB 8978-1996,with the removal rates of Cd,Cr,Cu and Ni ranging from 43.8% to 100% and removal rates of chlorobenzene compounds from 80% to 100%.
