Overview
Zhejiang wastewater treatment plant serves Shangyu District, Shaoxing, Zhejiang, China, with a population of 350,000. The facility has a designed capacity of 1.00 unit, reflecting its role in municipal wastewater management.
The Zhejiang wastewater treatment plant is located in Cao'e Street, Shangyu District, Shaoxing City, Zhejiang Province, China. It serves a population of approximately 350,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1.00, indicating its scale in handling municipal wastewater from the urban area. As a major treatment facility in Zhejiang Province, the plant operates under China's national wastewater discharge standards, which are aligned with the Water Pollution Prevention and Control Law. For large agglomerations like this, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B discharge standards, depending on the sensitivity of the receiving water body. Regulatory expectations for facilities of this size are stringent. The treated effluent is discharged into local water bodies that eventually flow into the Qiantang River estuary and Hangzhou Bay, part of the East China Sea. This coastal region supports diverse aquatic life and is an important ecological zone. The plant's operations are critical for protecting downstream water quality and maintaining the ecological health of the bay and adjacent marine environment.
Environmental context
The plant discharges into the local watershed, which drains into the Qiantang River and ultimately Hangzhou Bay in the East China Sea. This coastal area supports diverse marine life and is an important nursery ground for fish and shellfish. The region's water quality is influenced by urban runoff and industrial discharges, making effective wastewater treatment essential for preserving the ecological balance of the bay and protecting downstream habitats.
