城市垃圾渗滤液污染控制技术综述

介绍了垃圾填埋场渗滤液的来源以及水质特点,结合国内外研究和应用实例,对垃圾渗滤液处理方式及处理技术进行了综述。比较了合并处理等三种垃圾渗滤液处理方式的优缺点,阐述了物化处理技术和生物处理技术在垃圾渗滤液处理中的应用。在此基础上,建议渗滤液处理应综合考虑水质水量、经济技术及环境等因素,优先考虑场内建设渗滤液处理系统,对于难处理的渗滤液可以考虑采用"预处理-生化处理-高效物化"联合工艺处理。

Review on Controlling Technology for Urban Landfill Leachate Pollution

The characteristics, origin and processing methods of landfill leachate were summarized. Combined with research and engineering, process technologies of landfill leachate were generalized. Advantages and disadvantages of three landfill leachate treatment methods were compared. Physical - chemical treatment technologies and biological treatment technology of leachate treatment were described. In selection of leachate treatment methods, the factors of water quality, economic technology and environment conditions should be considered. This study concluded that the processing system of ＂pre - treatment - biological treatment - physical - chemical treatment＂ can be considered when leachate was difficult to handle.
