摘要
主要阐述了微孔曝气型Carrousel-2000氧化沟工艺除磷脱氮的优点、运行过程中存在的问题和相应的解决方法.采用该工艺处理后的出水指标:化学需氧量(CODCr)低于50 mg/L,总磷低于1 mg/L,氨氮低于5 mg/L,达到了GB18918-2002城镇污水处理厂污染物排放标准的一级标准.
The advantages of microporous aeration carrousel 2000 oxidation ditch process on nitrogen and phosphor removal are introduced in this paper. The problems in running the process and their corresponding solution are also described. The water quality after treatment is： chemical oxygen demand（CODer）value less than 50mg/L,total phosphorus value less than 1mg/L,ammonia nitrogen value less than 5mg/L, which can meet the first class of GB18918-2002 People＇s Republic China national standard for urban sewage treatment plant pollutant emission standards.
