Overview
Nei Mongol wastewater treatment plant serves Chaoyang in Liaoning, China, with a population equivalent of 100,000. The facility operates under China's national wastewater discharge standards.
The Nei Mongol wastewater treatment plant is located in Yuhu Community, Jianping County, Chaoyang City, Liaoning Province, China. It serves a population equivalent of approximately 100,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment with nutrient removal in sensitive watersheds. The regulatory framework mandates compliance with effluent limits for COD, BOD, ammonia nitrogen, and total phosphorus. The plant discharges into the local water system within the Daling River basin, which flows through Liaoning Province before reaching the Bohai Sea. The receiving waters support agricultural irrigation and aquatic habitats, making effective treatment essential for downstream water quality and ecosystem health.
Environmental context
The plant's treated effluent enters the Daling River system, which drains into the Bohai Sea via the Liaodong Bay. The Daling River basin supports diverse aquatic life and is used for irrigation in the surrounding agricultural region. The Bohai Sea is a semi-enclosed water body with significant ecological and economic importance, including fisheries and mariculture, making nutrient and pollutant control critical for preventing eutrophication and protecting marine biodiversity.
