摘要
脱氮除磷是市政污水处理难度的集中体现,通过实例,对污水处理厂生化系统的脱氮除磷运行进行了分析评价,根据影响脱氮除磷的主要因素的分析,提出了工艺改进的办法,对利用传统方法进行脱氮除磷的污水处理厂提供了有益借鉴。
Municipal wastewater nitrogen and phosphorus removal are difficult to deal with. Nitrogen and phosphorus removal with chemical and biological system in sewage treatment plant was analyzed and evaluated by some examples. Then, improvement approach of the process was put forward by analyzing the main factors of nitrogen and phosphorus removal. The article provides a useful method for sewage treatment plants with traditional methods to remove nitrogen and phosphorus.
