保温生物介质氧化处理农村生活污水的应用研究进展

RESEARCH PROGRESS OF BIOLOGICAL INSULATION DIELECTRIC OXIDATION TREAMTNE METHOD IN THE APPLICATION OF RURAL DOMESTIC SEWAGE

保温生物介质氧化处理方法是一种高效、低耗、运行简便的分散式农村生活污水处理技术,其出水可达GB18918—2002《城镇污水处理厂污染物排放标准》一级A标准限值。介绍了保温生物介质氧化处理方法的工艺流程、系统结构以及优势,并详细概括了保温生物介质氧化处理方法的关键性问题:填料的选择和制备、水力负荷的选择、填料层厚度的选择以及剩余污泥等问题。

Biological insulation dielectric oxidation treatment method is a kind of highly efficient,low consumption,simple handing decentralized treatment technology for rural domestic sewage. And the effluent could reach the level A of the ＂Urban Sewage Treatment Plant Pollutant Discharge Standards＂（ GB 18918—2002）. This article introduced the process flow,the system structure and the advantages of biological insulation dielectric oxidation treatment method,and summarized the key issues of this technology,such as selection and preparation of the filler,hydraulic load,filler layer thickness and excess sludge.
