Overview
Henan wastewater treatment plant serves Linzhou City in Henan Province, China, with a population of 134,100. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Linzhou City, Henan Province, China, at Tianping Avenue in the Longshan subdistrict. It serves a population of approximately 134,100, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, away from coastal areas, and its treated effluent likely discharges into local rivers that ultimately flow into the Yellow River basin. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. The plant's operational context aligns with national requirements for urban wastewater treatment in Henan Province. The plant plays a critical role in protecting local water bodies and downstream ecosystems. Its treated effluent likely enters the Qi River or a tributary of the Hai River system, which flows through Henan and into the Bohai Sea. By reducing pollutant loads, the facility helps maintain water quality in the region's agricultural and urban waterways, supporting aquatic life and downstream water users.
Environmental context
The plant's treated wastewater likely discharges into the Qi River, a tributary of the Hai River system, which flows through Henan Province and ultimately reaches the Bohai Sea. This watershed supports diverse aquatic life and is used for irrigation and industrial water supply. The facility's nutrient removal is crucial to prevent eutrophication in downstream reservoirs and coastal zones.
