Overview
Guangdong wastewater treatment plant serves Pingshi Town, Lechang, Shaoguan, Guangdong, China, with a population of 64,000. It operates under China's national wastewater discharge standards.
The Guangdong wastewater treatment plant is located in Pingshi Town, Lechang City, Shaoguan, Guangdong Province, China. It serves a population of approximately 64,000 residents in this urban area of northern Guangdong. As a municipal plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for COD, BOD, ammonia nitrogen, and total phosphorus. For a plant serving a medium-sized agglomeration, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent is discharged into local waterways that ultimately flow into the Bei River system, a major tributary of the Pearl River. The Pearl River Delta downstream is an ecologically important region supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment helps protect downstream water quality and ecosystem health.
Environmental context
The plant discharges into the Bei River watershed, which flows southward into the Pearl River and then into the South China Sea. The Pearl River Delta is a densely populated and industrialized region where nutrient pollution from wastewater can contribute to eutrophication and harm aquatic ecosystems. Effective treatment at this plant helps reduce the load of organic pollutants and nutrients entering the river system, supporting the ecological health of downstream waters.
