低碳源污水的脱氮除磷技术研究进展
|
摘要
随着社会经济的快速发展与人们生活水平的提高,用水量的增加使得污水处理厂中的有机物含量逐渐降低,而磷含量则较高,因而在污水脱氮除磷处理中,低碳源污水成为发展的瓶颈。COD含量的降低使得污水在采用生物法进行脱氮除磷处理时,微生物新陈代谢过程所需的碳源不足,进而对出水中氮磷含量造成影响,导致出水达不到相关标准。在碳源不足的前提下,污水排放氮、磷不达标会使污水排放问题更为突出,因此亟须开发高效经济的污水处理技术,旨在提高氮、磷去除率。
With the rapid development of social economy and the improvement of people 's living standards,the increase of water consumption makes the organic matter content in sewage treatment plant gradually reduce,while the phosphorus content is higher,so in the treatment of wastewater nitrogen and phosphorus removal,low carbon source sewage has become a bottleneck of development. With the decrease of COD content,the carbon source needed in the process of microbial metabolism is insufficient,which affects the nitrogen and phosphorus content in effluent and leads to the failure of effluent to meet the relevant standards. Under the premise of insufficient carbon source,the problem of sewage discharge will be more prominent if nitrogen and phosphorus are not up to the standard. Therefore,it is urgent to develop efficient and economical sewage treatment technology to improve the removal rate of nitrogen and phosphorus.
