Overview
Liaoning wastewater treatment plant serves Yingkou, Liaoning, China, with a designed capacity of 1.00 unit. It supports a population of 133,000 and is located within 50 km of the coast.
The Liaoning wastewater treatment plant is situated in the Yingkou High-tech Industrial Development Zone, Xishi District, Yingkou City, Liaoning Province, China. It serves a population of approximately 133,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1. Under China's national wastewater standards, plants serving over 100,000 people are typically required to implement advanced treatment to protect sensitive water bodies. The regulatory framework, including the Water Pollution Prevention and Control Law, mandates stringent effluent limits for such facilities. While the exact treatment level is unspecified, the plant likely operates with secondary or tertiary treatment to comply with local environmental requirements. The plant's discharge ultimately reaches the Bohai Sea via local rivers and coastal waters. The Bohai Sea is a semi-enclosed marginal sea that supports diverse marine life and is ecologically sensitive due to industrial and urban runoff. The plant's proximity to the coast (within 50 km) underscores the importance of effective nutrient removal to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant's treated effluent flows into the Liao River system, which drains into the Bohai Sea. The Bohai Sea is a critical marine habitat for fisheries and migratory species, but it faces challenges from nutrient pollution and algal blooms. Effective wastewater treatment is essential to minimize ecological impacts on this coastal environment.
