Overview
Guangdong wastewater treatment plant serves Jiangmen City, Guangdong Province, China, with a designed capacity of 1.00 and a population served of 253,000. It is located within 50 km of the coast, discharging into the Pearl River Delta system.
The Guangdong wastewater treatment plant is a municipal facility located in Jiangmen City, within the Pearl River Delta region of Guangdong Province, China. Serving a population of 253,000, it is classified as a large agglomeration under Chinese wastewater regulations, which mandate secondary treatment as a minimum standard for such scales. As a plant in China, it operates under the national Water Pollution Prevention and Control Law and the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). These regulations require advanced treatment (Class 1A or 1B) for plants discharging into sensitive water bodies, which is typical for facilities in the densely populated and industrialized Pearl River Delta. The plant's treated effluent is discharged into the local river network, which ultimately flows into the Pearl River Estuary and the South China Sea. This coastal discharge zone supports diverse marine life and is an important fishing ground, making effective nutrient removal critical to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant discharges into the Pearl River Delta, a complex network of rivers and estuaries that drains into the South China Sea. This region is ecologically sensitive, supporting diverse aquatic habitats and serving as a nursery for many fish species. The coastal waters are influenced by tidal flows and receive nutrient inputs from multiple urban and industrial sources, requiring stringent treatment to maintain water quality.
