Overview
Hebei wastewater treatment plant serves Sanhe City in Hebei Province, China, with a population equivalent of 60,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Sanhe City, Langfang Prefecture, Hebei Province, China. It serves a population of approximately 60,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a plant serving 60,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant discharges treated effluent into local waterways that ultimately flow into the Hai River basin, which drains into the Bohai Sea. This coastal discharge area is ecologically sensitive, supporting fisheries and marine biodiversity, making effective treatment crucial for protecting downstream aquatic environments.
Environmental context
The plant's treated effluent enters the local river network within the Hai River basin, which flows eastward into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it vulnerable to nutrient pollution from upstream sources. The plant's discharge contributes to the overall nutrient load affecting coastal ecosystems, including fisheries and migratory bird habitats.
