摘要
连续流砂反硝化过滤作为一种新型的脱氮污水深度处理工艺,具有集混凝、澄清、过滤及反硝化等功能为一体的连续自动清洗的优点,不仅能达到去除悬浮物(SS)和总磷(TP)的功能,在二沉池出水中进行反硝化脱氮中具有很好的生物脱氮功能。出水达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A类排放标准。
As a new type of treatment to remove nitrogen from municipal waste water, continuous sand filter with denitrification has its advantages of mixing, clarification and denitrification. Not only did it remove SS and TP, but also the nitrogen can be removed effectively from secondary effluent. After the processing, the main pollutant discharge target achieved 1A discharge standard of pollutants for municipal wastewater treatment plant （GB 18918-2002）.
