Overview
Shandong wastewater treatment plant serves Longkou City, Shandong Province, China, with a population equivalent of 250,000. 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 located in Longkou City, Yantai, Shandong Province, China. It serves a population equivalent of 250,000, placing it in the large agglomeration category. The facility is situated in the eastern coastal region of China, an area with significant industrial and urban development. As a large-scale plant in China, it operates under the national wastewater discharge standards (GB 18918-2002) and local environmental regulations. The plant's designed capacity is 1. For agglomerations of this size, Chinese regulations typically require secondary treatment with nutrient removal to protect sensitive water bodies. The plant's treated effluent likely discharges into the Bohai Sea via local rivers or coastal outfalls, given its proximity to the coast (within 50 km). The Bohai Sea is a semi-enclosed water body that receives substantial nutrient inputs from surrounding urban and agricultural areas, making effective wastewater treatment critical for controlling eutrophication and maintaining marine ecosystem health.
Environmental context
The plant is located in the coastal region of Shandong Province, within the drainage basin of the Bohai Sea. Treated wastewater likely flows through local rivers or directly into the Bohai Sea, a semi-enclosed sea with limited water exchange. The Bohai Sea supports important fisheries and aquaculture but faces challenges from nutrient pollution and harmful algal blooms. Effective treatment at this plant helps reduce nitrogen and phosphorus loads, protecting downstream marine habitats and coastal water quality.
Frequently asked questions
The Shandong wastewater treatment plant is located in Longkou City, Yantai, Shandong Province, China. Its address is Donglai Street, Longkou, Yantai, Shandong, 265700.
The plant serves a population equivalent of 250,000 people, classifying it as a large agglomeration under Chinese wastewater regulations.
The plant is located within 50 km of the coast, so treated wastewater likely discharges into the Bohai Sea via local rivers or coastal outfalls, following Chinese discharge standards.
The plant operates under China's national wastewater discharge standard GB 18918-2002 and local environmental protection regulations. Large agglomerations like this typically require secondary treatment with nutrient removal to protect sensitive coastal waters.
For a plant of this scale in China, standard treatment includes secondary biological treatment with nitrogen and phosphorus removal, often using activated sludge processes, to meet Class 1A or 1B discharge limits under GB 18918-2002.
