Overview
The Shandong wastewater treatment plant serves 182,200 people in Kuiwen District, Weifang, Shandong, China. It has a designed capacity of 1.00 unit and operates under China's national wastewater regulations.
The Shandong wastewater treatment plant is located in Kuiwen District, Weifang City, Shandong Province, China. It serves a population of 182,200, classifying it as a medium-to-large agglomeration under Chinese standards. The plant's designed capacity is 1.00, though the unit is unspecified. As a municipal facility, it plays a key role in managing wastewater from the urban area. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits based on the receiving water body's sensitivity. For plants serving over 100,000 people, advanced treatment is often required to meet Class 1A standards, especially in environmentally sensitive areas. Typical facilities in this region employ biological treatment with nutrient removal. The plant discharges treated effluent into local waterways that eventually drain into the Bohai Sea via the Xiaoqing River or other tributaries. The Bohai Sea is a semi-enclosed water body facing eutrophication and pollution challenges, making effective wastewater treatment critical for protecting marine ecosystems and coastal communities.
Environmental context
The plant's treated effluent flows into the Xiaoqing River system, which drains into Laizhou Bay and ultimately the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it vulnerable to nutrient pollution and algal blooms. Effective treatment at this plant helps reduce nitrogen and phosphorus loads, supporting the ecological health of downstream fisheries and coastal habitats.
