Case Study on the Application of a Sewage Treatment Plant in a County of Baoji City, Shaanxi Province

Project Name: Sewage Treatment Plant of a Certain County in Baoji, Shaanxi Province
Processing Capacity: 5,000 m³/d
Treatment Process: Bar Screen + MBR Process
Effluent Standard: Class A Standard specified in the "Integrated Wastewater Discharge Standard for the Yellow River Basin of Shaanxi Province" (DB61/224-2018)

The total processing capacity of the county's sewage treatment plant is 5,000 cubic meters per day, with a total land area of 5,788 square meters, approximately 0.58 hectares. Upon completion of the project, the sewage collection rate and treatment rate within the planned area are expected to reach 100%. This initiative will effectively address public welfare needs, enhance environmental protection efforts, improve urban development quality, and significantly contribute to the improvement of surface water quality in the region.

Online COD ammonia nitrogen total phosphorus total nitrogen analyzer

The county's sewage treatment plant has installed automatic analyzers for COD, ammonia nitrogen, total phosphorus and total nitrogen from BOQU at the inlet and outlet respectively. In the process technology, ORP, fluorescent dissolved oxygen, suspended solids, sludge concentration and other equipment are used. At the outlet, a pH meter is installed and a flowmeter is also equipped. To ensure that the drainage of sewage treatment plants meets the A standard stipulated in the "Integrated Wastewater Discharge Standard for the Yellow River Basin of Shaanxi Province" (DB61/224-2018), the sewage treatment process is comprehensively monitored and controlled to guarantee stable and reliable treatment effects, save resources and reduce costs, truly realizing the concept of "intelligent treatment and sustainable development".
