Overview
Henan wastewater treatment plant serves Pingyu County in Henan Province, China, with a population of 75,200. The plant operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Qinghe Subdistrict, Pingyu County, within the city of Zhumadian, Henan Province, China. It serves a population of approximately 75,200, classifying it as a medium-sized municipal facility. The plant is situated inland, away from coastal areas, and its operations are integral to local water management. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national standard sets effluent limits for various pollutants, and plants of this scale typically employ secondary biological treatment or advanced treatment to meet these requirements. The regulatory framework ensures that treated wastewater meets environmental protection goals. The plant discharges into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward into the Yellow Sea, supporting diverse aquatic ecosystems and providing water for agriculture and industry. The plant's performance is crucial for protecting downstream water quality and the ecological health of the Huai River basin.
Environmental context
The plant's treated effluent enters local streams that are part of the Huai River basin, one of China's major river systems. The Huai River flows through densely populated agricultural regions before reaching the Yellow Sea. The basin supports a variety of aquatic life and is important for irrigation and drinking water supplies. Effective wastewater treatment is essential to prevent nutrient pollution and maintain the ecological balance of this vital watershed.
