Shanxi Wastewater Treatment Plant, Tianzhen County, Shanxi Province, China

The Shanxi wastewater treatment plant is located in Tianzhen County, Datong City, Shanxi Province, China. It serves a population of approximately 40,000 residents in the Yuzhen area. As an inland facility, it plays a key role in managing municipal wastewater for this part of northern China. Under China's national wastewater regulations, plants serving populations of this scale are typically required to meet secondary treatment standards, with some regions mandating tertiary treatment for sensitive water bodies. The plant operates within the framework of China's Water Pollution Prevention and Control Action Plan, which sets discharge limits and promotes advanced treatment technologies. The treated effluent from the plant is discharged into local rivers that eventually flow into the Hai River basin, which drains into the Bohai Sea. This watershed supports agricultural irrigation and provides water for downstream communities. Proper treatment is essential to protect water quality in this semi-arid region where water resources are scarce.

The plant discharges into local waterways that are part of the Hai River basin, which ultimately flows into the Bohai Sea. This region experiences a continental monsoon climate with dry winters and wet summers, making water quality management critical for both ecological health and human use. The downstream environment supports diverse aquatic life and provides water for irrigation, so effective treatment helps prevent eutrophication and contamination.
