摘　　要：某污水处理厂原有主体工艺为改良式序列间歇反应器(MSBR),处理规模为20万m^(3)/d。由于水量增加、水质波动与冬季低温的影响,无法满足新排放标准的要求,需要进行升级改造。该工程实例根据计算确定填料体积以及好氧池、厌氧池容积,在污水处理厂原址基础上对MSBR池体构造进行重新布置,并配合设备的改造。将MSBR工艺改造为移动床生物膜反应器(MBBR)工艺,使出水氨氮、TN质量浓度由原来满足限值5(8)、15 mg/L升级到满足限值1.5(3)、10 mg/L。MBBR工艺在生物池内增加了大量填料,微生物浓度高、脱氮效果好,在无法增加占地的污水处理厂的升级改造中具有明显的优势。The original main process of a wastewater treatment plant(WWTP)is the MSBR process,with a treatment capacity of 200000 m^(3)/d.However,due to the increase in water volume,fluctuations in water quality,and low winter temperatures,it is unable to meet the requirements of the new discharge standards and needs to be upgraded and reconstructed.Based on the calculated volume of fillers and the capacity of aerobic and anaerobic tanks,this engineering example rearranges the structure of the MSBR tank on the basis of the original site of the WWTP,and cooperates with equipment renovation to transform the MSBR process into the MBBR process,upgrading the effluent mass concentration of ammonia nitrogen and TN from the original limit of 5(8),15 mg/L to meet the limit of 1.5(3),10 mg/L.The MBBR process has added a large amount of fillers in the biological tank,with high microbial concentration and good denitrification effect.It has obvious advantages in the upgrading and renovation of WWTPs that cannot increase land occupation.
