Treatment of landfill leachate by using electron beam technology

Abstract

Abstract:

The raw liquid and the bio-treatment（MBR） effluent of landfill leachate were irradiated using electron beam（EB） technology. The effect of EB irradiation on the molecular weight，organic composition of pollutants in the landfill leachate，as well as the improvement of biodegradability were investigated. Results showed that EB irradiation coupled with the coagulation process achieved a good COD removal of landfill leachate. Furthermore，the macromolecular organic pollutants（molecular weight >100 ku） in the leachate solution could be destroyed while some small molecular weight organics（molecular weight，0.5-1 ku） would be polymerized during the EB irradiation. Additionally，EB irradiation could effectively remove macromolecular humus in the bio-treatment effluent of the leachate and transform them to small molecular weight organic compounds which would enhance the biodegradability of the landfill leachate.

Key words: electron beam, irradiation, landfill leachate, biodegradability

摘要：

采用电子束治污技术对垃圾渗滤液原液及生化MBR产水进行辐照处理，通过对比电子束辐照处理前后渗滤液中污染物分子质量、有机成分的变化，以及可生化性的改善，对辐照技术处理渗滤液的效果进行了考察。研究结果显示，电子束辐照耦合混凝工艺对垃圾渗滤液COD的去除具有较好的效果；电子束辐照在将渗滤液原液中大分子有机污染物（分子质量100 ku以上）破坏的同时，会促进部分较小分子质量有机物（分子质量0.5~1 ku）发生聚合；此外，电子束辐照可有效去除渗滤液生化MBR产水中的大分子腐殖质类物质，促进大分子有机物转化为小分子物质，并提升渗滤液的可生化性。
