摘要
为满足流域综合整治需求,解决目前污水处理能力不足的问题,昆山市某镇在两个污水泵站建设移动式一体化处理设备,主体工艺采用多点进水、倒置AAO-MBR工艺对污水进行处理。采用BIOWIN软件对该工艺的运行效果进行模拟优化,并验证该工艺处理污水的能力。结果表明,BIOWIN软件能够很好地模拟倒置AAO-MBR工艺处理高浓度生活污水,使生活污水出水指标能够达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A排放标准。经过现场一年的运行,在进水COD_(Cr)≤400 mg/L、氨氮≤45 mg/L、TN≤50 mg/L、TP≤5 mg/L、水温≥10℃的情况下,系统运行平稳,出水指标全部达到GB 18918—2002一级A排放标准,并达到《地表水环境质量标准》Ⅳ类水质质量标准,该工艺处理污水的运行费用为1.258元/m^(3)。因此,倒置AAO-MBR工艺具有良好的处理生活污水的能力,并且运行费用较低。
In order to meet the needs of comprehensive remediation demand for river basin and solve the problem of insufficient sewage treatment capacity at present,a town in Kunshan City had built mobile integrated treatment equipment in two sewage pumping stations.The main process adopted multi-point influent and reversed AAO-MBR process.The BIOWIN software was used to simulate and optimize the operation effect of the process,and to verify the ability of the process to treat sewage.Results showed that the BIOWIN software could well simulate the reversed AAO-MBR process for the treatment of high concentration domestic sewage,so that the domestic sewage could meet the first class A criteria of Discharge Standard of Pollutant for Municipal Wastewater Treatment Plants(GB 18918-2002).After one year of yield operation,when the COD_(Cr)≤400 mg/L,ammonia nitrogen≤45 mg/L,TN≤50 mg/L,TP≤5 mg/L and water temperature≥10℃,the system could operation stable,all the effluent indices reached the first class A criteria of GB 18918-2002,and reached the water quality standard of classⅣof Environmental Quality Standard for Surface Water.The operation cost of sewage treatment by this process was 1.258 yuan/m3.Therefore,the reversed AAO-MBR process could treat domestic sewage well,and the operating cost was low.
