垃圾渗滤液污水处理厂工艺流程设计优化探讨

Discussion on Optimal Design of Treatment Process of Waste Leachate Plant

不同类型的垃圾处理项目中产生的各类渗滤液都含有大量对环境和人类有严重危害性的物质,必须有效的处理才能达标排放或利用。而渗滤液污水污染物浓度高、水质成分复杂、含有大量有机污染物、氨氮含量高、水质差异大,处理难度大,没有普遍适用的工艺,每个渗滤液处理项目都需要根据项目具体情况确定合理可行的污水处理工艺。本文就垃圾渗滤液污水处理工艺设计进行探讨,为渗滤液的工艺设计提供借鉴和参考。

Massive leachate is produced by different waste disposal projects, and it contains a large number of substances which are seriously harmful to the environment and human beings. The leachate must be treated effectively to meet wastewater discharge standards or water reuse standards. In view of high concentration of pollutant, complex component, high concentration of organic contaminant, good biodegradability, high concentration ammoniacal nitrogen and large difference in water quality, so no process is universally applicable for the treatment of different types of leachate. Various factors should be considered comprehensively for process optimization. This paper discusses the design of waste leachate treatment process, and puts tbrward some proposals for reference.
