强化生化法和双膜组合工艺处理垃圾渗滤液的应用

The Applied Study of Strengthen Biochemical-Membrane Technique in Landfill Leachate Treatment Project

摘要: 本文介绍了生化法+双膜工艺在垃圾渗滤液处理工程中的运行实例，结果表明，强化生化法能够很好地去除COD、NH3-N等，去除率分别达到76%和99.5%，从而减少对后续膜的污染。生化出水经过后续膜处理后，色度、SS、有机物进一步被去除，COD去除率达95%以上，色度去除率达99.4%，最终出水能稳定达到《生活垃圾填埋场污染物排放标准》(GB16889-2008)。生化与双膜组合工艺应用于垃圾渗滤液的处理具有较好的发展前景。

Abstract: This paper introduces the biochemical-membrane technique in landfill leachate treatment engi- neering examples. The results show that strengthened biochemical method is able to remove COD and NH3-N. The removal rate respectively reached 76% and 99.5%, which can avoid pollution on the subsequent membrane. The subsequent double membranes can further remove chromaticity, SS and organic matter. The removal rate of COD was above 95%, and the removal rate of the chromaticity reached 99.4%. The effluent can reach “life landfill pollutant discharge standard” (GB16889-2008). The biochemical-membrane technique in landfill leachate treatment project has better development prospects.
