Overview
Liaoning wastewater treatment plant serves Linghai City in Liaoning Province, China, with a population equivalent of 126,000. The plant has a designed capacity of 1.00 (units unspecified) and is located inland, more than 50 km from the coast.
The Liaoning wastewater treatment plant is a municipal facility serving the city of Linghai (凌海市) in Liaoning Province, China. It is situated in the Jinzhou prefecture-level city area, within the broader Liaoning region. The plant serves a population equivalent of 126,000, placing it in the medium-to-large agglomeration category under typical Chinese wastewater management frameworks. As a Chinese wastewater treatment plant, it operates under the national regulatory framework, which includes the Water Pollution Prevention and Control Law and discharge standards such as GB 18918-2002. For plants serving populations over 100,000, secondary treatment with nutrient removal is generally required, especially for discharge into sensitive water bodies. The designed capacity is reported as 1. The plant discharges treated effluent into local waterways that ultimately drain into the Bohai Sea via the Liao River system. The receiving water body is part of an ecologically important coastal basin that supports fisheries and migratory bird habitats. The plant's performance is critical for protecting downstream water quality and the marine environment of the Bohai Sea.
Environmental context
The plant's treated effluent flows into the Liao River system, which drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea is ecologically significant, supporting diverse marine life and serving as a spawning ground for commercial fish species. The region's watershed is also important for migratory birds along the East Asian-Australasian Flyway. Protecting water quality in this basin is essential for maintaining the health of coastal ecosystems and the livelihoods dependent on them.
