Overview
Shandong wastewater treatment plant serves Shouguang City in Shandong Province, China, with a population equivalent of 89,000. The facility operates under China's national wastewater discharge standards.
The Shandong wastewater treatment plant is located in Shouguang City, part of Weifang Prefecture in Shandong Province, eastern China. It serves a population equivalent of approximately 89,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese municipal plant, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. Plants serving populations over 50,000 are typically required to achieve at least Class 1-B standards, with many in sensitive watersheds targeting Class 1-A. The regulatory framework ensures baseline treatment performance. The plant discharges into the local watershed within the Hai River basin, which ultimately drains into the Bohai Sea. The region is an important agricultural area, and the plant's effluent quality directly affects downstream water bodies used for irrigation and ecological support. Proper treatment helps protect the Bohai Sea from nutrient loading and pollution.
Environmental context
The plant's receiving water body is part of the Hai River system, which flows into the Bohai Sea, a semi-enclosed marginal sea with limited water exchange. The Bohai Sea faces eutrophication risks from agricultural runoff and municipal discharges. The plant's location in Shandong's agricultural heartland means its treated effluent supports local water reuse and helps maintain downstream aquatic habitats, including wetlands that provide migratory bird stopover sites.
