Zhejiang Wastewater Treatment Plant, Jiaojiang District, Taizhou, Zhejiang Province, China

The Zhejiang wastewater treatment plant is located in the Jiaojiang District of Taizhou, a coastal city in Zhejiang Province, China. It serves a population of approximately 3,000 people, placing it in the small agglomeration category under Chinese wastewater regulations. The facility is situated near the Jiaojiang River, which flows into the East China Sea. Chinese wastewater treatment plants serving populations of this scale typically employ secondary biological treatment processes such as activated sludge or sequencing batch reactors. The plant has a designed capacity of 1.00 unit, though the exact unit of measurement is unspecified. Under China's national wastewater discharge standards (GB 18918-2002), small-scale plants are required to meet Class 1-B or Class 2 effluent limits depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into the Jiaojiang River, which flows through Taizhou and eventually reaches the East China Sea. The coastal location means the discharge may affect marine water quality, particularly in the sensitive coastal zone of Zhejiang Province. The region supports important fisheries and aquaculture, making proper treatment essential for protecting downstream ecosystems and human health.

The plant's discharge enters the Jiaojiang River, which flows through Taizhou and empties into the East China Sea. This coastal watershed supports diverse marine life and is important for local fisheries. The proximity to the coast means that treated effluent must meet stringent standards to protect the sensitive marine environment from nutrient pollution and other contaminants.
