摘　　要：【目的】某污水处理厂设计处理规模为1.2×10^(5) m^(3)/d,设计出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准,现要求出水达到一级A标准。【方法】拟接入的某面板项目废水规模为2.5×10^(4) m^(3)/d,废水可生化性较差,经过方案比选采用臭氧高级氧化在厂外进行预处理后与生活污水混合后进入污水处理厂。综合考虑排放标准、提标改造要求和现状用地等因素,将污水处理厂现状“悬挂链式移动曝气工艺”改造为“厌氧/缺氧/好氧(AAO)+膜生物反应器(MBR)”工艺,同时结合实际进水碳氮比(C/N),适量投加碳源,满足提标要求,出水稳定达到一级A标准。【结果】生化+多相组合膜生物反应器(MP-MBR)工艺具有显著的生化处理效果和截留作用。此工程提标改造厂区未新增用地,建设周期远低于传统工艺。【结论】文章为厂区用地有限、出水水质要求高和要求不停产施工的类似污水处理厂的提标改造提供了参考。[Objective]The designed treatment capacity of a wastewater treatment plant(WWTP)is 1.2×10^(5) m^(3)/d.The design effluent quality implements the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002)classⅠgrade B standard,and the effluent is required to meet the classⅠgrade A standard.[Methods]The wastewater scale of the proposed panel project to be connected is 2.5×10^(4) m^(3)/d.The biodegradability is poor,and after scheme comparison,ozone advanced oxidation is used for pre-treatment outside the plant,and then mixed with domestic wastewater before entering WWTP.Taking into account factors such as discharge standards,upgrading requirements,and current land use,the current"suspended chain mobile aeration process"in WWTP will be transformed into an"AAO+membrane bioreactor(MBR)"process.At the same time,combined with the actual influent C/N ratio,carbon sources will be added appropriately to meet the upgrading requirements.[Results]The biochemical+multiphase membrane bioreactor(MP-MBR)process have significant biochemical treatment effects and retention effects.The upgrading and reconstruction of the factory area in this project had not added any new land,and the construction period is much lower than that of traditional processes.[Conclusion]The paper provides a reference for the renovation and reconstruction of similar WWTP with limited land use in the factory area,high requirements for effluent quality,and non-stop construction requirements.
