摘要:

国内的某个以城市污水为循环冷却水补充水源的工程项目,夏季在运行过程中偶尔会出现澄清池出水呈现酸性的现象。经过分析、研究得出了造成这一现象的原因:澄清池入口处氨氮浓度偏高,污水深度处理中没有专门的氨氮脱除单元,并对这一现象所造成的后果进行了分析。曝气生物滤池在处理城市污水二级出水中的氨氮方面具有很大的优点,现在被广泛地应用到城市污水回用项目中脱除氨氮。

Abstract:

During the course of the project that municipal sewage is reused for recycling cooling water in domestic power plant running,occasionally the effluence of clarifier appears to be acidic in summer.The reason of this phenomenon has been analysed and studied.It indicates that the concentration of nitrogen at the entrance of clarifier was higher and there was not a special unit for nitrogen removal in the advanced wastewater treatment.Aerobic biological filter has a great advantage in removing nitrogen from the secondary treatment effluence of municipal sewage,and nowit has been widely used in the project of municipal wastewater reuse.

Key words: municipal effluent, advanced treatment, ammonia-nitrogen, reuse
