高级氧化技术深度处理垃圾渗滤液工程实例

The Project of Advanced Oxidation Technology for Treating Landfill Leachate

垃圾渗滤液成分复杂,有机负荷高,水质水量变化大,且含有氨氮等对生物有毒的物质,属于极难处理的高浓度废水,生化处理的出水水质难以达到《生活垃圾填埋场污染控制标准》(GB16889-2008)的排放要求,需进一步深度处理。本文重点介绍了"化学氧化+曝气生物滤池(BAF)"深度处理工艺的原理、特点,并对其工程实例进行了讨论。该工艺具有投资运行成本低,处理效率高,无二次污染等特点,为垃圾渗滤液的低碳、高效处理提供了新方法和途径。

Landfill leachate is extremcly difficult to treat because of high and complex organic load, changes on water quality and quantity, ammonia and other toxic substances. The cffiuant quality is difficult to achieve ＂Solid Waste Landfill Pollution Control Standard＂ （GB16889-2008） only through biological treatment, mad it needs further advanccd treatment. This article focuses on the principle mad features of ＂chemical oxidation ＋ biological aerated filter （BAF）＂ technology. This technology shows the advantages of low investment cost, high efficiency, no secondary pollution. It provides a new way tbr low-carbon, efficient treatment of landfill leacbate.
