This case introduces the Jiangning Science Park river sewage treatment project, which uses our factory's high-efficiency dissolved air flotation to treat river sewage. This equipment removes more than 90% of suspended solids and total phosphorus in the water body, and can reduce the COD value at the same time. After comprehensive treatment, it meets the fourth category of surface water environmental quality standards. Good results have been achieved.
This case mainly introduces the installation of dissolved air flotation (DAF) process facilities in the upgrade and renovation project of the x water plant to deal with the adverse effects of low-turbidity and high-algae raw water on the water treatment process. Taking this project case as an example, it introduces the raw water quality of the water plant, the problems existing in the original method and the selection of the renovation process, the design of the dissolved air flotation process, the selection of dissolved air flotation equipment and matters of concern, and the actual operation effect.
