Shandong Wastewater Treatment Plant, Licang District, Qingdao | Coastal China Facility

The Shandong wastewater treatment plant is located in Licang District, Qingdao, Shandong Province, China. It serves a population of approximately 134,000 people, placing it in the medium-to-large agglomeration category under Chinese wastewater regulations. The plant's address is near the跨海大桥高架路 (Cross-Sea Bridge Expressway) in the Fushan Road subdistrict. As a municipal facility in China, the plant is expected to comply with the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants. For a plant of this scale, secondary treatment with nutrient removal is typically required, especially given its proximity to coastal waters. The designed capacity is reported as 1. The plant discharges treated wastewater into the local water system, which ultimately drains into the Yellow Sea via the Jiaozhou Bay. This coastal discharge point is ecologically significant as the Yellow Sea supports diverse marine life, including fisheries and migratory species. The plant's location within 50 km of the coast underscores the importance of effective treatment to protect marine water quality.

The plant's treated effluent flows into the Jiaozhou Bay, a semi-enclosed basin connected to the Yellow Sea. The Yellow Sea is a marginal sea of the Pacific Ocean, known for its high biodiversity and as a critical habitat for migratory birds along the East Asian-Australasian Flyway. The bay supports local fisheries and aquaculture, making nutrient and pollutant control essential to prevent eutrophication and maintain ecosystem health.
