摘要
改良型Carrousel 氧化沟耦合工艺处理低碳氮比的生活污水,是采用间歇曝气模式,氧化沟出口的溶解氧为2.0～3.0 mg/L,污泥浓度为 2 500～3 500 mg/L,污泥回流比为 80%～95%.在TN和氨氮常年超标的情况下,投加葡萄糖碳源,可以使该污水处理厂改良型Carrousel氧化沟工艺去除低碳氮比的生活污水中的氨氮、总氮、总磷、CODCr、BOD5 及酸碱度的效果很好,出水完全符合《城镇污水污水处理厂污染物排放标准》(GB 19918-2002)[1]的要求.
Abstract
The improved Carrousel oxidation ditch coupling process is used to treat low carbon to nitrogen ratio domestic sewage.Intermittent aeration mode is adopted,and the dissolved oxygen at the outlet of the oxidation ditch is 2.0～3.0 mg/L,sludge concentration is 2 500～3 500 mg/L,sludge reflux ratio is 80%～95%.When TN and ammonia nitrogen exceed the standard year-round,glucose carbon source is added.The improved Carrousel oxidation ditch of the sewage treatment plant removes ammonia nitrogen,total nitrogen,total phosphorus,CODCr from low carbon to nitrogen ratio domestic sewage The effects of BOD5 and pH are very good,and the effl uent fully meets the Class A Standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plants(GB 19918-2002).
