摘　　要：为了高效培养AAO工艺菌种,实现城镇污水处理厂的快速投产,以广东省某污水处理厂为例,介绍了污泥培养驯化过程和经验。该污水处理厂设计规模为3×10^(4)m^(2)/d,采用AAO+磁混凝沉淀工艺。利用大粪和地脚粉作为碳源培养菌种,实现了短时间、低成本高效率的培养,培养驯化周期为30 d,吨水成本为0.171元,调试期间二沉池出水满足一级A标准。研究分析了污泥培养驯化中易发生的污泥絮体变小现象,提出了减少曝气量、增加外回流量降低二沉池负荷等解决措施,为同类污水处理厂调试和试运行提供参考。In order to cultivate efficient strains of AAO process and realize the rapid operation of urban wastewater treatment plant(WWTP),a WWTP in Guangdong province is taken as an example to the experiences of sludge cultivation and domestication.De-sign capacity of the WWTP is 3×10^(4)m^(2)/d,which adopts AAO+magnetic coagulation and sedimentation process.Dung and grand dust flour were used as carbon source culture strains to realize the cultivation in a short time,performed low cost and high efficiency.The cultivation domestication period was 30 d and the cost was 0.171 yuan/t.During the commissioning.the ffluent of the secondary sedimentation tank could meet the first grade A standard.Research analyzed the phenomenon of sludge flocs becoming smaller in sludge cultivation and domestication,and proposed solutions such as reducing aeration,increasing external reflux rate,and reducing the load of secondary sedimentation tanks,etc.,which can provide references for commissioning and trial operation of similar WWTPs.
