Overview
Shandong wastewater treatment plant serves Changyi City in Shandong Province, China, with a designed capacity of 1.00 (units unspecified) and a population equivalent of 145,800.
The Shandong wastewater treatment plant is located in Changyi City, within the Kuiju subdistrict of Weifang, Shandong Province, China. It serves a population equivalent of 145,800, classifying it as a large agglomeration under typical regulatory frameworks. The plant's designed capacity is reported as 1. As a facility in China, the plant operates under national wastewater discharge standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For a plant of this scale, secondary treatment with nutrient removal is typically required, especially if discharging into sensitive water bodies. The plant's receiving water body is not explicitly named, but given its inland location (more than 50 km from the coast), it likely discharges into a local river or stream that flows into the Bohai Sea via the Wei River or other tributaries. The plant plays a key role in protecting local water quality and downstream ecosystems in the Shandong Peninsula region.
Environmental context
The plant is situated inland in Shandong Province, more than 50 km from the coast. Its treated effluent likely enters a local river system that drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea supports diverse marine life and is an important fishing ground, but it faces eutrophication pressures from agricultural and urban runoff. Proper treatment at this plant helps reduce nutrient and pollutant loads to the downstream watershed.
