摘要
鄂尔多斯市某污水处理厂采用曝气沉砂池+改良型卡鲁塞尔氧化沟+氯消毒工艺,原出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准。为使出水水质达到一级A标准,将改良型卡鲁塞尔氧化沟内现有的倒伞表面曝气改为底部曝气,增加氧化沟缺氧段池容,并新增中间提升泵房+高密度沉淀池+超滤的深度处理单元。污水处理厂提标改造后近一年的运行结果表明,出水水质稳定,各指标均满足设计标准。
A wastewater treatment plant in Ordos adopted the process of aerated grit chamber,modified Carrousel oxidation ditch and chlorine disinfection.The original effluent quality carried out the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).In order to improve the effluent quality to meet the first level A criteria,the existing surface aeration by inverted umbrella in the modified Carrousel oxidation ditch was changed to bottom aeration,which increased the tank capacity of the anoxic section of the oxidation ditch,and added the advanced treatment units of middle lift pump,Densadeg and ultrafiltration.The operation results of the sewage treatment plant for nearly a year after the transformation showed that the effluent quality was stable,and all the indexes met the design discharge standard.
