垃圾渗滤液主要来自于填埋场和焚烧厂渗滤液,但是随着垃圾分类的开展,湿垃圾厌氧发酵后的沼液以及垃圾中转站产生废水也成为垃圾渗滤液的主要来源之一.渗滤液水质成分十分复杂,所含污染物浓度高、处理难度大,且随着现在各项技术的不断发展,渗滤液处理技术形成了多元化的局面,本文介绍了四种不同来源的渗滤液水质特点及现有处理技术现状,给出了不同来源渗滤液处理技术的工艺流程,分析了不同工艺流程的特点及应用场景,同时结合"碳达峰、碳中和"背景,及垃圾分类的开展和填埋场渗滤液排放标准的修订,分析了渗滤液处理技术现状及未来发展的趋势.
Present Situation and Future Development Trend of Landfill Leachate Treatment Technology
The landfill leachate mainly comes from landfill and incinerator leachate,but with the development of garbage classification,the biogas liquid after anaerobic fermentation of wet garbage and the wastewater generated by garbage transfer stations have also become one of the main sources of garbage leachate.The leachate has high concentration of complex pollutants and great difficulty in treatment.With the continuous development of various technologies,the leachate treatment technology has formed a diversified situation.This paper introduces the water quality characteristics of four different sources of leachate and the current situation of existing treatment technology,gives the process flow of leachate treatment technology from different sources,and analyzes the characteristics and application scenarios of different process flows.At the same time,combined with the background of"carbon peak,carbon neutralization"and the development of garbage classification and the revision of leachate discharge standards in landfills,the current situation and future development trends of leachate treatment technology are analyzed.
