膜生物反应器在垃圾渗滤液处理工程中的应用研究

Engineering application of membrane bioreactor in treatment of landfill leachate

介绍膜生物反应器的基本原理、优点、类型和影响因素,总结膜生物反应器在垃圾渗滤液处理工程中的应用现状及进展。工程应用实践表明,膜生物反应器固液分离效果好、污泥负荷高、可截留大分子难降解有机物、剩余污泥产量低、占地面积小、易于实现自动化,在垃圾渗滤液处理领域具有很好的应用前景。根据工程实际经验,针对膜生物反应器在渗滤液处理工程中的应用,提出工程设计和运行控制方面的建议。

this paper introduced principles and characters of membrane bioreactor and its application in treatment of landfill leachate. In such application, membrane bioreactor, small in size, less ex- cess sludge produced, capable of loading large amount of sludge, was good at solid - liquid separa- tion and intercepting large molecular, difficult - degraded organics. It had a bright prospect of engi- neering application in treatment of landfill leachate.
