摘　　要：通过对南宁市城南填埋场渗沥液历年实测水量水质的研究,系统分析其区域性特征,并与广西区内及国内类似工程的渗沥液进行对比分析可知:渗沥液产生量计算时渗透系数宜取技术规范中的较大值,结果与实测值最为接近;渗沥液主要水质指标CODCr、BOD5、NH3-N等季节性波动较小,比区外同期渗沥液水质浓度均相对偏低。在此基础上,合理确定南宁市填埋场渗沥液处理升级改造工程的设计进水水量和水质。By studying on water quantity and quality of waste leachate from Nanning Chengnan Waste Sanitary Landfill Site for the past years, its regional characteristics were systematically analyzed, and the characteristics of waste leachate were compared with the other similar projects in China. The results showed that the calculated value of leachate output was closed to its measured value when permeability coefficient was taken larger value in technical code. Seasonal fluctuations of major water quality indexes of leachate from Guangxi were smaller, such as CODCr, BOD5, NH3-N, and they were lower than contemporaneous leachate from outside. And it was key to determine the design parameters of water quantity and quality for leachate treatment reconstruction project in waste landfill sites of Nanning.
