Shandong Wastewater Treatment Plant, Dongying District, Shandong, China

The Shandong wastewater treatment plant is located in Dongying District, Dongying City, Shandong Province, China. It serves a population of approximately 230,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant's address is on Dongyi Road, Dongying District, within the urban infrastructure of the region. As a facility serving over 200,000 people, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national regulation sets effluent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients, with more stringent requirements for plants discharging into sensitive water bodies. The plant's designed capacity of 1.00 unit provides baseline operational scale. The plant discharges treated effluent into the local watershed, which ultimately drains into the Bohai Sea via the Yellow River Delta. The Yellow River is China's second-longest river and supports extensive agricultural and industrial activity. The downstream environment includes ecologically sensitive wetlands and coastal zones that provide habitat for migratory birds and aquatic species. Proper treatment is critical to protect these ecosystems from nutrient pollution and other contaminants.

The plant's treated effluent flows into the Yellow River basin, which empties into the Bohai Sea via the Yellow River Delta. This delta is an ecologically sensitive area supporting diverse aquatic life and serving as a critical stopover for migratory birds along the East Asian-Australasian Flyway. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making effective treatment essential for maintaining water quality and ecosystem health.
