Overview
Hebei wastewater treatment plant serves Luquan District, Shijiazhuang, Hebei Province, China, with a population of 82,000. The plant operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Luquan District, Shijiazhuang, Hebei Province, China. It serves a population of approximately 82,000 people, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving populations of this scale, secondary biological 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's treated effluent likely discharges into local waterways that drain into the Hai River system, which flows into Bohai Bay. The Hai River basin is a heavily urbanized and industrialized region, making effective wastewater treatment critical for protecting downstream aquatic ecosystems and coastal water quality in the Bohai Sea.
Environmental context
The Hebei plant discharges into the Hai River basin, which flows through Hebei Province and Tianjin before emptying into Bohai Bay. The Hai River system supports diverse aquatic life and provides water for agriculture and industry, but faces challenges from urban runoff and industrial pollution. Effective treatment at this plant helps reduce nutrient and pollutant loads to the bay, which is ecologically sensitive due to its semi-enclosed nature and history of algal blooms.
Frequently asked questions
The Hebei wastewater treatment plant is located in Luquan District, Shijiazhuang, Hebei Province, China.
The plant serves approximately 82,000 people, classifying it as a medium-sized municipal wastewater treatment facility.
The plant treats wastewater that would otherwise enter local waterways in the Hai River basin, which flows into Bohai Bay. By treating the water, it helps protect the Hai River system and the coastal environment of Bohai Bay.
The plant operates under China's national standard GB 18918-2002, which sets discharge limits for pollutants. For plants serving around 82,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the sensitivity of the receiving water body.
For medium-sized agglomerations in China, the typical treatment process includes primary sedimentation followed by secondary biological treatment, often using activated sludge or biofilm reactors. Nutrient removal (nitrogen and phosphorus) is commonly incorporated to meet stringent discharge standards, especially when the effluent enters sensitive water bodies.
