Guangdong Wastewater Treatment Plant, Zhongshan, Guangdong Province, China

The Guangdong wastewater treatment plant is situated in Zhongshan City, Guangdong Province, China, serving a population of 64,000. The facility is part of the municipal infrastructure in the rapidly urbanizing Pearl River Delta region, an area known for its dense population and industrial activity. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a scale appropriate for a medium-sized agglomeration. China's regulatory framework, including the Water Pollution Prevention and Control Law, sets effluent limits for pollutants such as COD, ammonia nitrogen, and total phosphorus. The plant's treated effluent likely discharges into local waterways that flow into the Pearl River system, eventually reaching the South China Sea. The Pearl River Delta is ecologically significant, supporting diverse aquatic life and providing critical habitat for migratory fish species. The proximity to the coast (within 50 km) underscores the importance of effective treatment to protect marine water quality.

The plant is located in the Pearl River Delta, a major river system that drains into the South China Sea. The receiving waters support a rich ecosystem, including estuarine habitats and fisheries. Effective wastewater treatment is crucial to prevent eutrophication and protect downstream coastal environments, which are important for biodiversity and local livelihoods.
