对保山市城区生活污水同步硝化反硝化脱氮的研究

摘要

由于传统的污水脱氮工艺普遍存在工艺流程长、占地面积大、基础投资高、需外加碳源等缺点,国内外众多学者相继开发了新型而且高效的脱氮工艺,这种新型技术在对生活污水中含有的硝酸盐类含氮类无机盐去除方面效果良好,具有能耗低、减少碳源的投加、产泥量少、占地面积小等优点,可大大降低运行费用,其实际应用前景十分广阔.对云南省保山市城区生活用水污染现状及其危害进行了研究,并对电极生物膜法同步硝化反硝化与传统生物脱氮工艺进行了描述和比较.%Due to the shortcomings of traditional wastewater denitrification processes, such as long process flow, large land occupation,high basic investment, and need for additional carbon sources, many scholars at home and abroad have developed new and efficient denitrification technologies. The new technology has good performance in treating nitrogen and inorganic salts containing domestic water. It has the advantages of low energy consumption,reduced carbon source dosage,less sludge produc-tion,and small floor space,and can greatly reduce the operating cost. The application prospect is very broad. The current status of domestic water pollution in Baoshan City,Yunnan Province,and its hazards were studied. Simultaneous nitrification and deni-trification using electrode biofilm method and traditional biological denitrification technology were described and compared.
