Overview
Anhui wastewater treatment plant serves Huangshan City, Anhui Province, China, with a population equivalent of 180,000. It discharges treated effluent into local water bodies within the Xin'an River basin.
The Anhui wastewater treatment plant is located in Huangshan City (Tunxi District), Anhui Province, China. It serves a population of approximately 180,000 people, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated near the Xin'an River, a major watercourse in the region. As a large-scale municipal facility, the plant is expected to meet China's national discharge standards, which typically require secondary or advanced treatment for plants serving over 100,000 people. The regulatory framework in China, governed by the Ministry of Ecology and Environment, sets effluent limits for key pollutants to protect receiving water bodies. Plants of this scale often incorporate biological treatment and nutrient removal to comply with standards. The treated wastewater is discharged into the Xin'an River system, which flows through the mountainous terrain of southern Anhui before eventually reaching the East China Sea. The river supports diverse aquatic life and provides water for downstream communities. The plant plays a critical role in maintaining water quality in this ecologically sensitive watershed, which is also a popular tourist destination known for its scenic landscapes.
Environmental context
The plant discharges into the Xin'an River, a tributary of the Qiantang River, which ultimately flows into the East China Sea near Hangzhou Bay. The watershed supports a variety of freshwater species and is an important water source for agriculture and urban use downstream. The region's mountainous terrain and seasonal rainfall patterns influence runoff and dilution capacity, making consistent treatment essential to prevent nutrient loading and algal blooms in downstream waters.
