Overview
Guangdong wastewater treatment plant serves Liwan District, Guangzhou, with a population of 1,500,000. The plant has a designed capacity of 1.00 cubic meters per second, operating under China's national wastewater standards.
The Guangdong wastewater treatment plant is located in Liwan District, Guangzhou, Guangdong Province, China. It serves a large urban population of 1,500,000 people, making it a significant facility in the region's wastewater infrastructure. The plant is situated in the densely populated Pearl River Delta, an area with high industrial and residential water demand. With a designed capacity of 1.00 cubic meters per second, the plant is sized to handle substantial wastewater flows. Under China's national wastewater discharge standards (GB 18918-2002), large municipal plants like this are typically required to achieve secondary treatment or higher, with nutrient removal in sensitive areas. Facilities serving over 1 million people in China generally employ advanced treatment processes to meet stringent effluent limits. The plant discharges into the Pearl River system, which flows through Guangzhou and into the South China Sea. The Pearl River Delta is a vital economic and ecological region, supporting diverse aquatic life and providing water for agriculture and industry. Proper wastewater treatment is critical to protect downstream water quality and the health of the delta's ecosystems.
Environmental context
The plant's treated effluent enters the Pearl River network, which drains into the South China Sea via the Pearl River Delta. This delta is a highly productive estuarine environment that supports fisheries, migratory birds, and mangrove habitats. The region faces challenges from urban runoff and industrial pollution, making effective wastewater treatment essential for maintaining water quality and ecological balance in the downstream coastal waters.
