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 highsludge 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.
