Overview
Shandong wastewater treatment plant serves Qingzhou in Shandong province, China, with a population equivalent of 116,000. The facility discharges into local waterways under China's national wastewater standards.
The Shandong wastewater treatment plant is located in Qingzhou, a city in Weifang prefecture-level city within Shandong province, China. The facility serves a population equivalent of 116,000, placing it in the medium-to-large agglomeration category under Chinese wastewater management frameworks. As a plant serving over 100,000 people, it is subject to China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment as a minimum and often requires advanced treatment for sensitive receiving waters. The plant's design and operation align with national policies aimed at reducing pollution in major river basins. The treated effluent is discharged into the local watershed, which ultimately drains into the Bohai Sea via the Xiaoqing River system. This coastal discharge contributes to the ecological health of the Bohai Sea, a semi-enclosed water body that supports fisheries and marine biodiversity. The plant plays a key role in protecting downstream water quality in a region with intensive agriculture and industry.
Environmental context
The plant's effluent enters the Xiaoqing River, a tributary of the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient loading and pollution. The plant's treatment performance directly affects the ecological balance of this marine environment, which supports commercial fisheries and migratory bird habitats along the Yellow Sea-Bohai Gulf coast.
Frequently asked questions
The plant is located in Qingzhou, a city in Weifang prefecture, Shandong province, eastern China.
The plant serves a population equivalent of 116,000, classifying it as a medium-to-large agglomeration under Chinese wastewater standards.
The treated effluent is discharged into the Xiaoqing River, which flows into the Bohai Sea, a semi-enclosed sea on China's northeast coast.
The plant operates under China's national standard GB 18918-2002, which sets discharge limits for pollutants. Plants serving over 100,000 people typically require secondary or advanced treatment.
For agglomerations of this size, Chinese regulations mandate at least secondary biological treatment, and often tertiary treatment if the receiving water body is environmentally sensitive.
