摘要
对于含有大量的BOD_5,COD,SS,NH_4-N、磷等污染物的某城市污水,采用设置厌氧、缺氧段的Carrousel氧化沟(即A^2/C氧化沟)工艺进行处理。运行结果表明,该工艺实现了无动力回流,流程简单,脱氮除磷效率高,处理出水达到了《城镇污水处理厂污染物排放标准》(GB 18918-2002)中的一级B标准。
In order to treat the municipal sewage containing lots of pollutants such as BOD_5,COD,SS,NH_4-N and phosphorus,the oxidation ditch(i.g.,A^2/C oxidation ditch) with the anaerobic and hypoxia segments is adopted.The operating results show that the use of the technology can achieve unpowered backflow and make the process simple,as well as improve the efficiency of nitrogen and phosphorus removal;the effluent treated with the technology can meet the first level B criteria of GB 18918-2002.
