Overview
Shandong wastewater treatment plant serves Penglai District, Yantai, Shandong, China, with a population of 48,000. The facility has a designed capacity of 1.00 cubic meters per day and is located within 50 km of the coast.
The Shandong wastewater treatment plant is located in Beigou Town, Penglai District, Yantai City, Shandong Province, China. It serves a population of approximately 48,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. As a facility in China, the plant operates under national wastewater discharge standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For agglomerations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive coastal areas. The plant's proximity to the coast suggests it may be subject to stricter effluent limits to protect marine environments. The treated effluent from the plant likely discharges into local waterways that flow into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea supports diverse marine life and is an important fishing ground, but faces eutrophication risks from nutrient inputs. Proper treatment at this plant helps mitigate impacts on coastal water quality and ecosystems.
Environmental context
The plant is located within 50 km of the coast, with treated effluent likely entering local rivers or streams that drain into the Bohai Sea. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it vulnerable to nutrient pollution and algal blooms. Protecting this marine environment requires effective nutrient removal and compliance with discharge standards to safeguard fisheries and biodiversity.
Frequently asked questions
The plant is located in Beigou Town, Penglai District, Yantai City, Shandong Province, China.
The plant serves approximately 48,000 people, classifying it as a medium-sized municipal facility.
Treated effluent is likely discharged into local waterways that flow into the Bohai Sea, a coastal marine environment.
The plant operates under China's national discharge standard GB 18918-2002, which sets limits for pollutants like COD, BOD, nitrogen, and phosphorus. Coastal plants may face stricter requirements to protect marine ecosystems.
For medium-sized agglomerations in China, secondary biological treatment with nutrient removal is standard, especially in sensitive coastal areas. This helps reduce nitrogen and phosphorus loads to prevent eutrophication.
