Overview
Guangdong wastewater treatment plant serves Doumen District, Zhuhai, China, with a designed capacity of 1.00 and population served of 200,000. It is located within 50 km of the coast.
The Guangdong wastewater treatment plant is situated in Doumen District (斗门区), Zhuhai, Guangdong Province, China. It serves a population of approximately 200,000, placing it in the large agglomeration category under Chinese wastewater regulations. The plant's designed capacity is 1. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The plant likely employs biological treatment processes such as activated sludge or A2O to achieve compliance. The plant discharges treated effluent into local waterways that ultimately drain into the Pearl River Delta and the South China Sea. Its proximity to the coast (within 50 km) means effluent may influence coastal water quality, requiring advanced treatment to protect marine ecosystems. The plant plays a key role in managing wastewater from a densely populated urban area in one of China's most industrialized regions.
Environmental context
The plant's treated effluent flows into the Pearl River Delta, a complex network of rivers and estuaries that discharge into the South China Sea. This region supports diverse aquatic life, including fisheries and migratory species, and is ecologically sensitive due to high urban and industrial activity. The plant's coastal proximity underscores the importance of effective nutrient removal to prevent eutrophication and protect downstream marine habitats.
