Shandong Wastewater Treatment Plant, Qingdao West Coast New Area

The Shandong wastewater treatment plant is located in Hongshiya Subdistrict, Qingdao West Coast New Area (Huangdao District), Qingdao City, Shandong Province, China. It serves a population of 26,400, placing it in the medium agglomeration category under Chinese wastewater regulations. China's wastewater treatment standards require secondary treatment for urban plants, with tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in 10,000 m³/day), and it operates under national discharge standards set by the Ministry of Ecology and Environment. The plant discharges into local rivers that flow into Jiaozhou Bay, a semi-enclosed sea area of the Yellow Sea. The bay supports diverse marine life and is an important ecological zone for fisheries and migratory birds.

The plant's treated effluent enters local watercourses that drain into Jiaozhou Bay, a coastal embayment connected to the Yellow Sea. Jiaozhou Bay is ecologically significant as a spawning ground for fish and a stopover for migratory waterbirds. The region's rapid urbanisation increases pressure on water quality, making effective treatment critical for maintaining the bay's ecological health.
