Analysis on key points of upgrading a semi-underground wastewater treatment plant
A wastewater treatment plant in Hefei province started upgrading and expansion projects in 2017.Due to the three-dimensional superposition of process units and the plane group layout of structures,the semi-underground wastewater treatment plant has a significant advantage in the design and construction of a small area,but it has become an obvious restriction factor in the technical transformation project.In the upgrading and renovation design of this project,based on the process accounting of existing facilities and the use of CFD fluid simulation and other technical measures,such as the transformation of the flow mode of the biochemical pond and the addition of the advanced treatment unit,the semi-underground wastewater treatment plant has achieved accu-rate transformation.Since the upgrading and renovation project was completed and put into opera-tion,the effluent quality of the project has steadily reached the assessment discharge standards and internal control water quality standards.
