Overview
Shandong wastewater treatment plant serves Haiyang, Shandong, China, with a population of 136,600. The plant 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 Haiyang, a coastal city in Shandong Province, China. It serves a population of approximately 136,600 people, placing it in the medium-to-large agglomeration category. The plant's designed capacity is 1. In China, wastewater treatment plants are regulated under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Plants serving populations over 100,000 typically require secondary treatment with nutrient removal, especially in sensitive coastal areas. The plant's proximity to the coast suggests that effluent quality must meet stringent limits to protect marine environments. The plant discharges into local waterways that ultimately flow into the Yellow Sea. The Yellow Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and migratory bird populations. Proper treatment is essential to prevent eutrophication and maintain water quality in this coastal ecosystem.
Environmental context
The plant's treated effluent likely enters local rivers or streams that drain into the Yellow Sea, a semi-enclosed sea with limited water exchange. The Yellow Sea supports diverse marine life, including important fish stocks and migratory birds. Nutrient pollution from wastewater can lead to algal blooms and hypoxia, making advanced treatment crucial for protecting this coastal environment.
Frequently asked questions
