啤酒废水改良Bardenpho工艺除磷脱氮技术研究_郭远凯

第32卷啤酒废水改良Bardenpho工艺除磷脱氮技术研究郭远凯，黎松强（嘉应学院化学系，广东梅州514015）摘要：Bardenpho工艺内循环和污泥均回流至A1池，使A1池和A2池均含有较多的NO3—N，对高氮的啤酒废水除磷效果有所影响。在Bardenpho工艺缺氧段前增设厌氧池，并分流70%回流污泥至缺氧池，保证了磷的有效释放及好氧段磷的吸收能力，提高了除磷效果。第二缺氧-好氧段延长污泥龄至10～16d，提高了脱氮处理效果。出水的氮磷水质均有明显提高（NH3—N2.15mg/L、TP2.40mg/L）。关键词：改良Bardenpho工艺；生物除磷脱氮；啤酒废水中图分类号：X172；TQ033文献标志码：A文章编号：1003-6504(2009)08-0120-03ImprovedBardenphoCraftforRemovalofPhosphorusandNitrogenfromBreweryWastewaterGUOYuan-kai，LISong-qiang（DepartmentofChemistry，JiayingUniversity，Meizhou514015，China）Abstract：InternalcycleandsludgefromBardenphoprocesswerebacktotankA1forcontainingmoreNO3-N，whichwillaffectphosphorusremovalofhighNbeerwastewater.Bardenphohypoxiaintheprocessofanaerobicbeforethenewpoolwilldistribute70%ofstreamingbacktohypoxiasludgepondforensuringtheeffectivereleaseofphosphorusandphosphorusabsorptionofaerobiccapacityandimprovetheeffectofphosphorusremoval.Thesecondhypoxia-aerobicsludgeextensionofageto10~16dwillenhancethetreatmenteffectofnitrogen.Theeffluentwaterqualitywasmarkedlyim
