Overview
Guangdong wastewater treatment plant serves Doumen District, Zhuhai, Guangdong, China, with a population of 180,000. The plant has a designed capacity of 1.00 cubic meters per day.
The Guangdong wastewater treatment plant is located in Doumen District, Zhuhai, Guangdong Province, China. It serves a population of approximately 180,000 people, classifying it as a large agglomeration under Chinese wastewater regulations. The facility is situated in the Pearl River Delta region, a densely populated and economically vital area. China's wastewater treatment standards are governed by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For large agglomerations like this one, secondary treatment with nutrient removal is typically required to protect receiving waters. The plant's designed capacity is 1. The treated effluent is discharged into local waterways that ultimately drain 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 coastal ecosystems.
Environmental context
The plant's discharge flows into the Pearl River system, which empties into the Pearl River Estuary and the South China Sea. This coastal region supports mangrove forests, seagrass beds, and important fish spawning grounds. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in the estuary, making effective treatment essential for maintaining water quality and biodiversity.
