摘要
阐述了城市污水处理中除磷的重要性和迫切性,而在普遍采用的生物除磷技术不能满足出水磷的排放标准时可考虑采用化学除磷技术。系统分析了化学除磷的原理、方法、工艺、研究进展及应用前景,并指出了现阶段化学除磷技术研究与发展的目标。
This paper expounded the significance and instancy of phosphorus removal from municipal wastewater, and the chemical technology of phosphorus removal could be utilized when the universally applied biological technology could not meet the phosphorus discharging requirements. The chemical principle, methods, project,new development and their applied prospect of phosphorus removal from wastewater were analyzed systematically. Also the aim was pointed out on chemical technology research and deveolopment of phosphorus removal from municipal wastewater nowadays.
