本文介绍了对垃圾渗滤液采用强化复合厌氧生物床反应器(ECAB) 好氧反应器(复合式SBR) 混凝后处理 超滤 纳滤的生物化集成处理的技术路线,工艺系统运行稳定,对有机物及总氮的去除效果良好,处理出水达到《生活垃圾填埋污染控制标准》(GB16889-1997)一级标准,且处理成本较低。文章并对存在的问题进行了分析。

Biochemical Treatment of Refuse Leachate——Technology Research on Comprehensive Treatment of Membrane Filtration

Because the quality of leachate is complex, the satisfactory processing effect can not be achieved by using physical chemistry or biochemistry processing method, therefore, research mainly focus on the integrated processing craft routes abroad and at home. At present, the processing craft routes are: the pretreatment anaerobic aerobic post-treatment. This topic key research integrated technology route is: Enhanced Compound Anaerobic Biological Bed (ECAB) SBR the coagulation post-processing membrane, the biochemistry and the transformation integration processing technical routes. The findings indicate, the system movement is stable, the organic matter and the total nitrogen removal shows good result. The internal filler has enhanced effect on ECAB and SBR; the membrane processing water has achieved the primary standard of "Contamination Control Standard on Domestic Refuse Landfill" (GB16889 - 1997); and the lower costs for leachate processing invested.
