Overview
Shaanxi wastewater treatment plant serves Shangzhou District, Shangluo City, Shaanxi Province, China, with a population of 200,000. The plant operates under China's national wastewater discharge standards.
The Shaanxi wastewater treatment plant is located in Shangzhou District, Shangluo City, Shaanxi Province, China, along the G312 highway in Dazhaoyu Subdistrict. It serves a population of approximately 200,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. As a plant of this scale in China, it is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus. Treatment typically involves secondary biological processes, with possible tertiary treatment for nutrient removal in sensitive watersheds. The plant discharges treated effluent into local water bodies that ultimately drain into the Danjiang River, a tributary of the Han River, which flows into the Yangtze River basin. This downstream connection to the Yangtze underscores the plant's role in protecting water quality in one of China's most ecologically and economically significant river systems.
Environmental context
The plant's treated effluent enters local streams that feed into the Danjiang River, part of the Han River system, which flows into the Yangtze River. The Yangtze basin supports diverse aquatic life, including endemic fish species, and provides water for millions of people. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream ecosystems and drinking water sources.
