Overview
Shandong wastewater treatment plant serves Changyi City in Shandong Province, China, with a population equivalent of 140,000. The facility has a designed capacity of 1.00 unit and is located within 50 km of the coast.
The Shandong wastewater treatment plant is a municipal facility serving Changyi City in Shandong Province, China. It is designed to handle wastewater from a population equivalent of 140,000, placing it in the large agglomeration category under typical Chinese regulatory frameworks. The plant's location in the coastal province of Shandong underscores its importance in managing urban wastewater in a region with significant industrial and agricultural activity. As a large-scale plant, it is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law, which mandates advanced treatment for sensitive coastal areas. The designed capacity of 1. Plants of this scale typically employ biological treatment with nutrient removal to protect receiving waters. The plant's discharge ultimately flows into the Bohai Sea via local waterways, a semi-enclosed sea that is ecologically sensitive due to limited water exchange. The region supports diverse marine life and is an important fishing ground. Effective wastewater treatment is critical to prevent eutrophication and protect coastal ecosystems in this densely populated and economically vital area.
Environmental context
The plant discharges into local rivers that drain into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea is ecologically sensitive, supporting diverse marine species and serving as a critical spawning and nursery ground for fisheries. Nutrient loading from urban and industrial sources poses a risk of eutrophication, making advanced wastewater treatment essential for maintaining water quality and ecosystem health in this coastal environment.
