纤毛状生物膜脱氮除磷工艺调试研究OA北大核心CSCDCSTPCD
Pilot-scale experiment on nitrogen and phosphorus removal by CNR process
纤毛状生物膜脱氮除磷工艺(CNR)是一种高效的生物脱氮除磷工艺.好氧池中纤毛状生物膜填料的添加,固化了大量世代时间长的硝化菌,提高了硝化反应速度,而且成功地解决了好氧段硝化菌与聚磷菌的泥龄矛盾.通过对天津某污水处理厂进行CNR工艺中试,得出结论如下:填料比表面积大,微生物附着量高达1 350～1 500g·m~(-2);填料容易挂膜、脱膜,无堵塞现象,更不需要反冲洗,维护管理简单;填料上形成的生物膜中,微生物体系稳定,种群丰富,微生物相包括钟虫(…查看全部>>
Cilium Nutrient Removal Process (CNR) is a novel technology that is effective for simultaneous nitrogen and phosphorus removal. The cilium-shaped media is fixed in aerobic tank and nitrobacteria with long generation time are attached to the media. Therefore, nitrification effect is strengthened greatly. Furthermore, the contradiction of sludge age between nitrohacteria and PAOs is resolved successfully. A pilot-scale experiment was carried out in a sewage tr…查看全部>>
