武夷山市污水处理厂处理效果与技术更新

Treatment Effects and Renewing Technology of Wuyishan Wastewater Treatment Plant

采用接触氧化法与高效垂直流人工湿地相结合处理城市生活污水,武夷山市污水处理厂经过2a多的运行,结果表明,该工艺对COD、BOD、SS、TN和TP的去除率分别达到86%、90%、76%、69%和51%,出水水质指标优于《城镇污水处理厂污染物排放标准》(GB18918-2002)的一级B标准,该工艺采用前置接触氧化法,具有占地少、处理效率高和运行管理简单等特点。为提高工程处理效率、完善工程运行管理,二期工程设计对一期工程存在的缺陷和不足进行改进,力求达到最佳效果。

The contact oxidation method combining to high efficient vertical flow constructed wetland has been applied to treat urban domestic sewage in Wuyishan wastewater treatment plant for more than 2 years. The results show that the process has high removal rate of COD （86%） , BOD （90%） , SS （76%） , TN （69%） and TP （51% ）. The water quality after treatment can reach B of the first class standard of ＂ Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant＂ （GB18918 -2002）. The process occupied small land with high treatment efficiency and easy management. The second period project design will improve the shortcomings of the first project to realize the optimum results.
