Overview
Shandong wastewater treatment plant serves Lingcheng District, Dezhou, Shandong, China, with a population equivalent of 130,000. The plant operates under China's national wastewater discharge standards.
The Shandong wastewater treatment plant is located in Lingcheng District, Dezhou City, Shandong Province, China. It serves a population equivalent of 130,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. The plant is expected to comply with these national standards, which set limits on biochemical oxygen demand, chemical oxygen demand, suspended solids, nitrogen, and phosphorus. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The downstream environment includes agricultural areas and the Bohai Sea, making nutrient control important for preventing eutrophication in coastal waters.
Environmental context
The plant's treated effluent flows into tributaries of the Yellow River, which discharges into the Bohai Sea. The Yellow River basin supports intensive agriculture and is ecologically sensitive to nutrient loading. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it vulnerable to algal blooms from excess nitrogen and phosphorus. Effective treatment at this plant helps protect both freshwater and marine ecosystems.
