This case study introduces how the Taizhou Jiangyan Biochemical Treatment Center Project uses our factory's high-efficiency dissolved air flotation to Reduce the content of organic matter and suspended solids in landfill leachate. After air flotation pretreatment, the concentration removal rate of suspended solids reaches more than 90%, and the grease removal rate reaches more than 95%, significantly reducing the burden of subsequent biochemical treatment.
Although automobile painting wastewater has high water quality complexity and is difficult to treat, it is necessary to classify, collect, and pre-treat wastewater according to quality as long as the characteristics of the wastewater are understood and appropriate treatment processes are adopted.
The wastewater generated during the coating production process of the enterprise has the characteristics of many types of pollutants, high concentration, complex composition, intermittent discharge of wastewater and irregular discharge time, poor biodegradability, etc. Reasonable selection of wastewater treatment methods and design of treatment processes that meet the requirements of the enterprise according to different process characteristics in accordance with local conditions can improve the treatment efficiency of wastewater, reduce treatment costs and shorten the treatment cycle.

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.
Nantong X Paper Co., Ltd. is located in Nantong City, Jiangsu Province. It is a papermaking company that uses recycled paper as raw material. During the production process, the daily discharge of wastewater is 8,000 to 10,000 m3. The recycled paper of the company is mainly made of waste newspapers, waste board paper and waste book and magazine paper.
