Overview
Shandong wastewater treatment plant serves Zhucheng, Shandong, China, with a population of 157,600. It operates under China's national wastewater standards, ensuring treated effluent meets environmental requirements.
The Shandong wastewater treatment plant is located in Zhucheng, a city in Shandong Province, China. Serving a population of approximately 157,600, it is a medium-to-large agglomeration facility that plays a key role in managing municipal wastewater in the region. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a facility of this scale, secondary treatment with nutrient removal is typically required to protect receiving waters. The plant discharges treated effluent into local waterways that eventually drain into the Bohai Sea via the Jiaolai River system. This coastal drainage makes nutrient control critical to prevent eutrophication in the Bohai Sea, a semi-enclosed water body sensitive to algal blooms.
Environmental context
The plant's treated effluent flows into the Jiaolai River basin, 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. Effective treatment at this plant helps reduce nitrogen and phosphorus loads that could otherwise contribute to eutrophication and hypoxia in coastal waters.
