2023年第3期环保科技Vol.29No.3MBBR工艺在农村生活污水处理中的应用姚宁波周凯＇李东於胜洪²黄青飞'徐玉璐!骆靖宇?（1.安徽舜禹水务股份有限公司，合肥231131;2.苏州首创嘉净环保科技股份有限公司，江苏苏州215126）摘要：MBBR工艺具有抗冲击负荷能力强、处理效率高、泥龄长、剩余污泥少的优点，在农村生活污水治理中得到广泛应用。文章阐述了MBBR工艺的结构组成、工艺特点，介绍了MBBR工艺在农村污水处理中的实际运行效果。通过试验发现,MBBR工艺对有机物和NH，-N的去除效率高，COD的平均去除率为72%,NH，－N的平均去除率为97.2%，出水COD和NH，-N满足GB18918-2002一级A排放标准;MBBR工艺对TP的平均去除率为22.2%，去除能力有限，出水TP的稳定达标需辅以化学除磷手段;MBBR工艺对TN的去除率最高可达80%，碳源不足是TN去除效果差的重要限制因素。文章研究结果可为MBBR的工程推广应用提供数据参考和技术支撑。关键词：MBBR工艺；工艺特点；农村生活污水处理；去除效果中图分类号：X703ApplicationofMBBRprocessinruraldomesticsewagetreatmentYaoNingbo',ZhouKai',LiDong',YuShenghong”,HuangQingfei',XuYulu',LuoJingyu?(1.AnhuiShunyuWaterAffairsCo.,Ltd.,Hefei231131;2.SuzhouCapitalGreinworthEnvironmentalProtectionTechnologyCo.,Ltd.,Suzhou215126)Abstract:MBBRprocesshastheadvantagesofstrongresistancetoimpactload,hightreatmenteffi-ciency,longsludgeageandlessvolumeofexcesssludge,andiswidelyusedinruraldomesticsew-agetreatment.ThispaperexpoundsthestructureandcharacteristicsofMBBRprocess,andintro-ducestheactualoperationeffectofMBBRprocessinruralsewagetreatment.TheresultsshowthatMBBRprocesshasahighremovalefficiencyoforganicsandNH,-N.TheaverageremovalrateofCODis72%,andtheaverageremovalrateofNH,-Nis97.2%.EffluentCODandNH,-Nval-uescanmeetthefirstclassAemissionstandardofGB18918-2002;theaverageremovalrateofTPbyMBBRprocessis22.2%,andtheremovalcapacityislimited,andthestablestandardmeetingofTPineffluentshouldbesupplementedbychemicalphosphorusremoval.ThemaximumTNremovalrateofMBBRprocesscanreach80%,andthelackofcarbonsourceisanimportantlimitingfactorforthepoorTNremovaleffect.Theresultsofthispapercanprovidedatareferenceandtechnicalsupportfortheengineeringpromotionanda...
