Overview
Liaoning wastewater treatment plant serves Shenyang, Liaoning province, China, with a population of 214,700. The plant operates under China's national wastewater standards.
The Liaoning wastewater treatment plant is located in Shenyang, the capital of Liaoning province in northeastern China. It serves a population of 214,700, placing it in the category of a medium-to-large agglomeration under Chinese municipal wastewater classification. 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 and nutrients. For plants serving over 200,000 people, advanced treatment with nutrient removal is typically required to meet Class 1A standards, especially in sensitive watersheds. The plant's treated effluent likely discharges into the Hun River, a tributary of the Liao River, which flows into the Bohai Sea. The Liao River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is crucial to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant is located in the Liao River basin, with effluent likely entering the Hun River, a major tributary. The Liao River flows into the Bohai Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The basin supports diverse aquatic habitats and is important for migratory fish species. Effective wastewater treatment helps reduce algal blooms and maintain water quality in this ecologically valuable region.
