污水脱氮除磷工艺研究

Research of the Process of Nitrogen and Phosphorus Removal from Polluted Water

针对我国污水体的富营养化问题,研究污水脱氮除磷的影响因素。目前,传统的脱氮除磷处理设施不能满足日益严峻的环境排放要求,需要开发研究新的工艺,以提高污水的处理能力。UCT工艺作为一项新开发的工艺,在传统的A2/0工艺的基础上,克服了传统方法不能同时高效脱氮除磷的缺点,通过二次回流,使脱氮除磷率得以进一步提升。

In view of the eutrophication problem of polluted water body in China, This article studies the influencial factors of nitrogen and phosphorus removal from polluted water. NP mainly comes from the industries, such as sewage, industrial wastewater, mines, chemical fertilizer, etc. Its emission must be controlled before it gets into the environment. At present, the conventional denitrification and dephosphorization treatment facilities cannot meet the requirement of the increasingly strict environmental emission standard, therefore new technology need to be developed to improve the processing capacity of sewage. As a newly developed technology, based on the traditional A2/0 process, UCT process overcomes the shortage of traditional method which cannot efficiently remove the Nitrogen and Phosphorus at the same time. Through the secondary backflow, nitrogen and phosphorus removal rate has further raised.
