Overview
The Guangdong wastewater treatment plant serves 78,000 people in Guangning County, Zhaoqing, Guangdong Province, China. It operates under China's national wastewater standards for municipal treatment.
The Guangdong wastewater treatment plant is located in Guangning County, within the city of Zhaoqing in Guangdong Province, China. It serves a population of approximately 78,000 people, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. As a plant serving a medium-sized urban population, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary biological treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes with anaerobic-anoxic-oxic (A2O) configurations to achieve the required effluent quality. The plant discharges treated effluent into local waterways that ultimately drain into the Pearl River Delta system, one of China's most ecologically and economically significant watersheds. The receiving waters support diverse aquatic life and are used for irrigation, fisheries, and industrial purposes downstream. Proper treatment is critical to prevent eutrophication and protect the sensitive estuarine environment of the Pearl River.
Environmental context
The plant's treated effluent flows into tributaries of the Bei River, a major branch of the Pearl River system. The Pearl River Delta is a densely populated and industrialized region where water quality management is crucial for both human use and ecological health. The downstream waters support important fisheries and migratory bird habitats, making nutrient removal and pathogen control essential for maintaining aquatic biodiversity and preventing algal blooms.
Frequently asked questions
The plant is located in Guangning County, Zhaoqing City, Guangdong Province, China.
The plant serves approximately 78,000 people, classifying it as a medium-sized municipal wastewater treatment facility.
The plant discharges into tributaries of the Bei River, which flows into the Pearl River system. This watershed is critical for water supply, fisheries, and ecological balance in the Pearl River Delta.
The plant operates under China's GB 18918-2002 standard, which sets discharge limits for pollutants like COD, BOD, ammonia, and phosphorus. Medium-sized plants like this are required to achieve secondary treatment with nutrient removal.
Plants of this scale in China commonly use activated sludge processes with biological nutrient removal, such as the A2O (anaerobic-anoxic-oxic) process, to meet the stringent effluent standards for sensitive water bodies.
