Overview
The Hebei wastewater treatment plant serves Neiqiu County in Hebei Province, China, with a population equivalent of 32,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Neiqiu County, Hebei Province, China. It serves a population equivalent of 32,000, placing it in the medium-scale category for municipal wastewater treatment in the region. The plant is situated inland, approximately 50 kilometers from the coast, and its operations are part of the broader water management infrastructure in Hebei Province. As a municipal facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets limits on key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus. For a plant serving a population of this size, 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 treated effluent from the plant is discharged into local watercourses that ultimately drain into the Bohai Sea via the Hai River system. The Hai River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. The plant's performance is critical to reducing nutrient loads that can cause eutrophication in downstream coastal waters.
Environmental context
The plant discharges into the Hai River basin, which flows into the Bohai Sea. This coastal sea is semi-enclosed and experiences periodic algal blooms due to nutrient pollution from agricultural runoff and municipal discharges. The plant's nutrient removal performance is therefore important for protecting the marine ecosystem and supporting fisheries in the Bohai Sea.
