Overview
The Hebei wastewater treatment plant serves Qinhuangdao, China, with a designed capacity of 1.00 and a population of 30,000. It is located within 50 km of the coast, discharging treated effluent into the local watershed.
The Hebei wastewater treatment plant is located in the Haigang District of Qinhuangdao, a coastal city in Hebei Province, China. The facility serves a population of approximately 30,000 and has a designed capacity of 1.00, indicating a small to medium-scale municipal treatment operation. As a Chinese wastewater facility, the plant operates under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for effluent quality. For plants serving populations around 30,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea that supports diverse marine life and is an important fishing ground. The plant's proximity to the coast (within 50 km) underscores the need for effective nutrient removal to prevent eutrophication in coastal waters.
Environmental context
The Hebei plant discharges into the local watershed that flows into the Bohai Sea, a semi-enclosed sea with limited water exchange. The Bohai Sea supports diverse aquatic life, including fish and shellfish, and is an important migratory corridor for birds. Nutrient loading from coastal discharges can contribute to algal blooms and hypoxia, making advanced treatment crucial for protecting this sensitive marine environment.
Frequently asked questions
The Hebei wastewater treatment plant is located in the Haigang District of Qinhuangdao, Hebei Province, China, near the coast of the Bohai Sea.
The Hebei plant serves a population of approximately 30,000 people in the Qinhuangdao area.
The Hebei plant discharges treated effluent into the local watershed, which ultimately flows into the Bohai Sea. The plant is within 50 km of the coast, so its discharge can affect coastal water quality.
The Hebei plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards.
In China, wastewater treatment plants serving around 30,000 people are typically designed with secondary treatment processes such as activated sludge, often including biological nutrient removal to meet national discharge standards and protect sensitive coastal waters.
