Overview
Shandong wastewater treatment plant serves Chengwu County, Shandong, China, with a population equivalent of 110,000. It operates under China's national wastewater discharge standards.
The Shandong wastewater treatment plant is located in Chengwu County, Heze City, Shandong Province, China. It serves a population of approximately 110,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in an inland area, over 50 km from the coast. As a facility serving over 100,000 people, it is subject to China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for such scales. The regulatory framework ensures compliance with national effluent limits. The treated wastewater likely discharges into local waterways within the Huai River basin, which ultimately drains into the Yellow Sea. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the region's densely populated and agriculturally active areas.
Environmental context
The plant discharges into local rivers that are part of the Huai River basin, which flows eastward into the Yellow Sea. This watershed supports diverse aquatic life and is important for regional agriculture and drinking water supplies. The plant's operations help mitigate nutrient pollution and protect downstream water quality in a region facing pressures from urbanization and industrial activity.
