Overview
Zhejiang wastewater treatment plant serves Yongjia County in Wenzhou, Zhejiang, China, with a population equivalent of 190,000 and a designed capacity of 1.00 (units unspecified).
The Zhejiang wastewater treatment plant is located in Yongjia County, part of Wenzhou city in Zhejiang Province, China. It serves a population equivalent of 190,000, placing it in the medium-to-large agglomeration category for Chinese wastewater infrastructure. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment, with many larger facilities implementing advanced treatment to meet stricter local discharge limits. The plant's designed capacity is reported as 1. This likely represents a standard measure such as 10,000 m³/day or similar. The plant discharges into the local water system within the Oujiang River basin, which flows into the East China Sea. The downstream environment includes the Wenzhou coastal area, supporting diverse aquatic life and important fisheries. Effective treatment is critical to protect water quality in this densely populated and economically active region.
Environmental context
The plant is located within the Oujiang River basin, which drains into the East China Sea near Wenzhou. The downstream environment includes coastal wetlands and estuarine habitats that support migratory birds and marine biodiversity. As the region experiences rapid urbanization, maintaining low nutrient and pollutant loads is essential to prevent eutrophication and protect downstream aquatic ecosystems.
Frequently asked questions
The plant is located on Yangguang Avenue in Yongjia County, Wenzhou, Zhejiang Province, China.
The plant serves a population equivalent of 190,000 people.
The plant has a designed capacity of 1.00, typically expressed in units such as 10,000 m³/day for Chinese facilities.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for COD, BOD, nitrogen, phosphorus, and other pollutants. Plants serving over 100,000 people are generally required to achieve at least Class I-A discharge standards.
For a plant of this scale in China, secondary biological treatment is standard, often with nutrient removal to meet Class I-A standards. Many facilities also incorporate advanced treatment processes like denitrification and phosphorus removal to protect sensitive downstream waters.
