垃圾渗滤液处理与清洁焚烧技术

Landfill leachate treatment and clean incineration technology

目前,随着我国城镇化发展力度的不断加大以及国民经济持续的快速增长,每年生活垃圾的产量也随之增加,垃圾渗滤液也大量增加。垃圾渗滤液具有有机污染物浓度高、成分复杂、毒性大以及难以降解等特征,目前各个垃圾填埋场面临如何对其进行有效处理是重要环保难题之一。本文总结了垃圾渗滤液的来源及其危害,对Fenton法、IOC-A/O-UF/NF/RO组合工艺等五种垃圾渗滤液处理方法进行了总结分析,探讨了垃圾渗滤液焚烧污染物减排技术,提出了未来垃圾渗滤液处理技术建议。

At present,with the increasing development of urbanization in China and the continuous improvement of people’s living standards,the amount of domestic waste generated has been increasing year by year,and a large amount of waste leachate has been generated.Waste leachate is characterized by high concentration of organic pollutants,complex composition,high toxicity and difficulty in degradation.Currently,landfills are faced with the challenge of how to effectively treat it,which is one of the important environmental protection problems.This paper summarizes the sources of waste leachate and its hazards,summarizes and analyzes five waste leachate treatment methods such as Fenton method and IOC-A/OUF/NF/RO combination process,discusses the waste leachate incineration pollutant reduction technology,and puts forward future waste leachate treatment technology suggestions.
