The Shandong wastewater treatment plant is located in Zhangdian District, Zibo City, Shandong Province, China. It serves a population equivalent of 149,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes with biological nutrient removal to meet Class 1A or 1B discharge standards. The plant discharges treated effluent into local water bodies within the Hai River basin, which ultimately drains into the Bohai Sea. The receiving environment supports diverse aquatic life and is subject to seasonal water quality challenges due to agricultural and industrial runoff in the region.
Environmental context
The plant's treated effluent enters the local network of rivers and canals within the Hai River basin, which flows into the Bohai Sea. This coastal sea is ecologically sensitive, supporting fisheries and migratory bird habitats. The region faces pressures from urbanization and industrial activity, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
