Overview
Shandong wastewater treatment plant serves Penglai District, Yantai, Shandong, China, with a population of 20,000. It has a designed capacity of 1.00 unit and is located within 50 km of the coast.
The Shandong wastewater treatment plant is located in Penglai District, Yantai City, Shandong Province, China. It serves a population of approximately 20,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant is situated in the coastal region of the Bohai Sea, an area with significant ecological and economic importance. As a facility serving a medium-sized population, the plant is expected to meet secondary treatment standards under China's national wastewater discharge regulations (GB 18918-2002). It operates within China's regulatory framework for municipal wastewater treatment. The plant's treated effluent likely discharges into local water bodies that flow into the Bohai Sea, a semi-enclosed marginal sea with sensitive marine ecosystems. The Bohai Sea supports fisheries, aquaculture, and biodiversity, making proper wastewater treatment critical for protecting water quality and marine life. The plant's proximity to the coast underscores the importance of effective nutrient removal to prevent eutrophication and algal blooms.
Environmental context
The Shandong plant is located in the coastal region of the Bohai Sea, a semi-enclosed sea connected to the Yellow Sea. The Bohai Sea receives freshwater from several rivers, including the Yellow River, and supports diverse marine life, including fish, shellfish, and migratory birds. The area is ecologically sensitive due to its role as a spawning and nursery ground for commercial fisheries. Discharges from coastal plants can contribute to nutrient loading and hypoxia, making advanced treatment important for preserving water quality and ecosystem health.
