Overview
Guangdong wastewater treatment plant serves 320,000 people in Chang'an, Dongguan, Guangdong, China. It has a designed capacity of 1.00 unit and is located within 50 km of the coast.
The Guangdong wastewater treatment plant is located in Chang'an, a town within Dongguan City, Guangdong Province, China. The facility serves a population of approximately 320,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated in the Pearl River Delta, a densely populated and industrialized region. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater treatment plants serving populations over 100,000. The designed capacity is recorded as 1.00, though the unit is unspecified. As a large-scale facility in a coastal province, it is subject to stringent effluent limits to protect downstream water quality. The plant discharges treated wastewater into the local water system, which ultimately drains into the Pearl River Estuary and the South China Sea. The Pearl River Delta is an ecologically sensitive region supporting diverse aquatic life and important fisheries. Proper treatment is critical to prevent eutrophication and protect marine habitats in the coastal waters.
Environmental context
The plant's treated effluent enters the local drainage network within the Pearl River Delta, flowing into the Pearl River Estuary and eventually the South China Sea. This coastal region supports important mangrove ecosystems, fish spawning grounds, and migratory bird habitats. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in the estuary, making advanced treatment essential for ecological health.
Frequently asked questions
The plant is located in Chang'an, Dongguan City, Guangdong Province, China, in the Pearl River Delta region.
The plant serves approximately 320,000 people, classifying it as a large urban agglomeration.
Treated wastewater is discharged into the local water system, which flows into the Pearl River Estuary and ultimately the South China Sea.
The plant operates under China's national wastewater discharge standards (GB 18918-2002), which mandate secondary treatment for facilities serving over 100,000 people, with stricter limits for sensitive coastal areas.
For large agglomerations in China, secondary biological treatment (e. g. , activated sludge) is standard, often with nutrient removal to meet Class 1A or 1B discharge standards, especially in coastal provinces like Guangdong.
