摘要
我国南方城市污水普遍存在低碳相对高氮磷特征,本文介绍了同时生物脱氮除磷的机理、对碳源的需求与竞争,以及一些针对此类污水生物脱氮除磷的改进工艺及其在实际运用中的效果,并对此类污水的处理方向进行了展望。
Municipal wastewater in most southern cities of China shares an identical characteristic of low carbon and high nitrogen-phosphorus concentration. This paper introduces the mechanism of simultaneous removal of nitrogen-phosphorus, as well as the requirements and competition of carbon sources. Some advanced processes concerning biological removal of nitrogen and phosphorus and their application effects were discussed. The future development of the technology was prospected.
