Overview
Guangdong wastewater treatment plant serves 350,000 people in Chenghai District, Shantou, Guangdong, China. It is located within 50 km of the coast, discharging into the South China Sea.
The Guangdong wastewater treatment plant is located in Chenghai District, Shantou City, Guangdong Province, China. It serves a population of 350,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in the Pearl River Delta region, a densely populated and economically vital area. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater. For a facility of this scale, advanced treatment may be expected to meet stringent effluent limits, especially given its proximity to sensitive coastal waters. The plant's treated effluent ultimately reaches the South China Sea via local waterways. This coastal discharge necessitates careful management to protect marine ecosystems, including coral reefs and fisheries. The plant plays a critical role in safeguarding water quality in the region, supporting both environmental health and human activities such as aquaculture and tourism.
Environmental context
The plant discharges into the South China Sea via the Han River system, which flows through Shantou and into the coastal waters. This area supports diverse marine life, including important fish spawning grounds and migratory species. The proximity to the coast increases the risk of nutrient pollution, which can lead to algal blooms and hypoxia. Effective treatment is essential to minimize ecological impacts on this productive marine environment.
Frequently asked questions
The plant is located in Chenghai District, Shantou City, Guangdong Province, China, near the coast of the South China Sea.
The plant serves approximately 350,000 people, classifying it as a large urban wastewater treatment facility.
Treated wastewater is discharged into local waterways that flow into the South China Sea, requiring careful management to protect coastal marine ecosystems.
China's national discharge standards, such as the GB 18918-2002, mandate secondary treatment for urban wastewater. Larger plants may require advanced treatment to meet stricter limits, especially in sensitive coastal areas.
For a plant of this size, secondary treatment is standard, but advanced treatment (tertiary) is increasingly common to reduce nutrients and protect receiving waters, particularly near the coast.
