Overview
Shandong wastewater treatment plant serves Laizhou City in Shandong Province, China, with a designed capacity of 1.00 and a population served of 190,000. It is located within 50 km of the coast, discharging into local water bodies.
The Shandong wastewater treatment plant is situated in Laizhou City, within Yantai Prefecture, Shandong Province, China. It serves a population of approximately 190,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1. As a large-scale municipal facility, the plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment as a minimum, with tertiary treatment required for sensitive receiving waters. Given its coastal proximity, the plant likely operates under stricter nutrient removal standards to protect marine environments. The plant's treated effluent is discharged into local waterways that ultimately drain into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea supports significant fisheries and aquaculture, making effective wastewater treatment critical to preventing eutrophication and maintaining water quality in this ecologically important region.
Environmental context
The plant's discharge enters the local river network, which flows into Laizhou Bay, part of the Bohai Sea. The Bohai Sea is a shallow, semi-enclosed basin with limited water exchange, making it vulnerable to nutrient pollution and algal blooms. The region supports diverse marine life, including commercial fish species and migratory birds, and is a key area for aquaculture. Effective treatment is essential to protect these ecological resources from excessive nutrient loads.
Frequently asked questions
The plant is located in Laizhou City, Yantai Prefecture, Shandong Province, China, near the coast of the Bohai Sea.
