Overview
The Hebei wastewater treatment plant serves Shijiazhuang, China, with a population equivalent of 70,000. It operates under China's national wastewater discharge standards, which mandate secondary treatment for urban plants of this scale.
The Hebei wastewater treatment plant is located in Shijiazhuang, the capital of Hebei Province in northern China. Serving a population equivalent of 70,000, the plant is part of the city's municipal wastewater infrastructure, handling domestic and industrial flows from the Chang'an District. Its location near the Hutuo River places it within the Hai River basin, a major water system in the region. China's wastewater treatment regulations, governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary biological treatment for urban plants serving agglomerations of this size. The standard also sets limits for nutrients and other pollutants, with stricter requirements for plants discharging into sensitive water bodies. Plants of this scale typically employ activated sludge or similar biological processes. The treated effluent from the plant is discharged into local waterways that eventually flow into the Hutuo River, a tributary of the Hai River system. The Hai River basin drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The plant plays a critical role in protecting the downstream aquatic environment from nutrient pollution and pathogens, supporting both ecological health and downstream water uses.
Environmental context
The plant discharges into the Hutuo River, a tributary of the Hai River system, which ultimately flows into the Bohai Sea. The Hai River basin is a densely populated and industrialized region facing significant water quality challenges from agricultural runoff and urban wastewater. The Bohai Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to eutrophication and algal blooms. Effective treatment at this plant helps reduce nutrient loads and protect the marine ecosystem.
Frequently asked questions
The Hebei wastewater treatment plant is located in the Chang'an District of Shijiazhuang, Hebei Province, China, near Xiangyang Street in Gaoying Town.
The plant serves a population equivalent of 70,000 people, making it a medium-sized municipal facility.
The plant protects the Hutuo River, a tributary of the Hai River system, which flows into the Bohai Sea. Its treatment reduces pollution in these water bodies.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for secondary treatment and nutrient removal.
For plants of this scale in China, secondary biological treatment (e. g. , activated sludge) is standard, often with additional nutrient removal to meet GB 18918-2002 standards.
