Overview
Henan wastewater treatment plant serves Mengzhou City in Henan Province, China, with a population equivalent of 59,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Mengzhou City, within Jiaozuo Prefecture, Henan Province, China. It serves an estimated population of 59,000 people, placing it in the medium-scale category for municipal wastewater treatment in the region. The plant is situated near the city's eastern ring road, reflecting its role in managing urban wastewater from the local community. As a Chinese municipal wastewater treatment facility, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For agglomerations of this size, secondary biological treatment is typically required, with potential additional nutrient removal if the receiving water body is in a sensitive area. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with national standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Yellow River basin via the Qin River system. The Yellow River is a major waterway in northern China, supporting agriculture, industry, and ecosystems. The plant's operation contributes to protecting downstream water quality and reducing pollution loads to the river, which is ecologically significant for the region's biodiversity and water resources.
Environmental context
The Henan plant discharges into the Qin River, a tributary of the Yellow River, which flows through Henan Province and eventually reaches the Bohai Sea. The Yellow River basin is ecologically sensitive, supporting diverse aquatic life and providing water for irrigation and human consumption. The plant's treated effluent helps maintain water quality in this important river system, which faces challenges from agricultural runoff and industrial discharges.
