Overview
The Liaoning wastewater treatment plant serves 150,000 people in Huludao, Liaoning Province, China. It has a designed capacity of 1.00 unit and is located within 50 km of the coast.
The Liaoning wastewater treatment plant is situated in Huludao, a coastal city in Liaoning Province, China. The facility serves a population of 150,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a large-scale municipal plant in China, it operates under the national wastewater discharge standards, which are aligned with the Water Pollution Prevention and Control Law. For plants serving over 100,000 people, advanced treatment is typically required to meet stringent effluent limits, especially in environmentally sensitive areas. Regulatory expectations for this population tier are high. The plant discharges treated wastewater into a local water body that ultimately drains into the Bohai Sea, a semi-enclosed sea with significant ecological importance. The Bohai Sea supports diverse marine life and is a critical fishing ground. The plant's proximity to the coast (within 50 km) underscores the importance of effective nutrient removal to prevent eutrophication and protect coastal ecosystems.
Environmental context
The plant's treated effluent flows into the local watershed, which drains into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea of the Pacific Ocean, known for its rich biodiversity and as a spawning ground for many fish species. The sea faces challenges from industrial and agricultural runoff, making effective wastewater treatment crucial for maintaining water quality and supporting marine life.
