- 摘要:
- 以温州市南片污水厂为例，介绍了污水厂出水达到浙江省清洁排放标准的提标改造设计方案。通过在原有工艺基础上进行分流，1.5×104 m3/d的分流污水采用“改良Bardenpho+二沉池+高密度沉淀池”工艺，而后与2.5×104 m3/d原工艺出水合并进行4×104 m3/d 污水的“反硝化深床滤池+臭氧接触氧化+消毒”的深度处理。该工程采用由设计单位牵头的联合体总承包模式实施，有利于发挥设计龙头作用，整合优势资源，与施工单位互为裨益，保障工程顺利实施。
- Abstract:
- Taking Wenzhou Nanpian sewage treatment plant as an example, this work introduces the upgrading and reconstruction program, which aims to meet the clean discharge standard of Zhejiang Province. The 1.5×104 m3/d of sewage from the original sewage treatment plant is introduced to bio-chemical treatment tank equipped with improved Bardenpho process, secondary clarification and highsludge sedimentation. And then, converged the original process effluent(2.5×104 m3/d), the advanced treatment processes, including denitrifying deep-bed filtration, ozone oxidation treatment and disinfection are used to upgrade the quality for the total sewage flow (4×104 m3/d). The EPC mode led by design institute is applied to this project, which is more conducive for the design institute to play a leading role. The design institute and the construction company can work together to ensure the implementation of the project.
