Overview
Hebei wastewater treatment plant serves Zunhua City in Hebei Province, China, with a population of 136,000. It operates under China's national wastewater standards.
The Hebei wastewater treatment plant is located in Zunhua City, Tangshan, Hebei Province, China. It serves a population of approximately 136,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in an inland area, contributing to the region's water infrastructure. As a facility serving over 100,000 people, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This regulation sets effluent limits for key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus. Typical plants of this scale employ activated sludge processes or similar biological treatment methods. The plant discharges treated wastewater into local water bodies that eventually drain into the Bohai Sea via the Luan River system or other regional waterways. The receiving environment supports aquatic life and is part of the broader Hai River basin, which is ecologically significant for northern China. Proper treatment helps protect downstream water quality and ecosystem health.
Environmental context
The plant's treated effluent flows into local rivers within the Hai River basin, which ultimately drains into the Bohai Sea. This coastal sea supports diverse marine life and is an important fishing ground. The watershed faces pressures from industrial and agricultural runoff, making effective wastewater treatment critical for maintaining water quality and ecological balance in the region.
