摘要
由于我国污水普遍存在C/N偏低问题,导致生物脱氮过程碳源不足使脱氮效果偏低,利用反硝化滤池进行深度脱氮成为国内外研究热点内容。在全面分析尾水深度处理背景和技术现状的基础上,概述了反硝化滤池工艺中核心滤料技术和研究现状,分析了天然纤维素材质滤料的优缺点,探讨了基于天然纤维素材质滤料的反硝化滤池脱氮效果提升急需解决的技术难题和基础理论,为天然纤维素材质滤料理论研究和反硝化滤池脱氮技术研发提供一定的参考。
The nitrogen removal efficiency was low due to insufficiency carbon source because the municipal wastewater has a low C/N ratio,the advancing nitrogen removal by using denitrifying filter was a hot issue in wastewater treatment fields.The paper analysed the background of the further treatment of effluent and technologies.We summarized the filters materials of the denitrifying filter and current situation,and investigated the characteristics of natural cellulose substances,discussed the technological problems and basic theories about enhancing nitrogen removal efficiency of denitrifying filters with natural cellulose substances.The studies can as references for investigating natural cellulose substances and denitrifying filters.
