Overview
Guangxi wastewater treatment plant serves approximately 90,000 people in Dahua County, Guangxi, China. The facility operates under China's national wastewater discharge standards.
The Guangxi wastewater treatment plant is located in Dahua County, part of the Guangxi Zhuang Autonomous Region in southern China. The facility serves an estimated population of 90,000, placing it in the medium-to-large agglomeration category for the region. As a municipal wastewater treatment plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets effluent limits for key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus, with different grades depending on the receiving water body's sensitivity. Plants serving populations over 100,000 typically require Class I-A or I-B standards, while smaller plants may meet Class II standards. The plant's treated effluent likely discharges into a local river within the Pearl River basin, which flows southward through Guangxi and into the South China Sea. The surrounding area features karst topography and ecologically sensitive waterways that support diverse aquatic life and agricultural activities. Proper treatment is essential to protect downstream water quality and the region's unique freshwater ecosystems.
Environmental context
The plant's treated effluent likely enters a tributary of the Hongshui River, part of the larger Pearl River system that drains into the South China Sea. The local watershed features karst landscapes with interconnected underground rivers and ecologically sensitive surface waters. Downstream environments support diverse aquatic species and provide water for irrigation and domestic use. Effective wastewater treatment helps prevent eutrophication and protects the ecological integrity of these freshwater systems.
Frequently asked questions
The plant is located in Dahua County, which is part of the Guangxi Zhuang Autonomous Region in southern China. The specific address is in Dahua Yao Autonomous County, Hechi City.
The plant serves approximately 90,000 people, classifying it as a medium-to-large agglomeration in the Chinese wastewater treatment context.
The treated effluent is likely discharged into a local river within the Pearl River basin, which eventually flows into the South China Sea. The plant's location in a karst region suggests discharge into surface waters or possibly underground rivers.
The plant operates under China's national standard GB 18918-2002, which sets discharge limits for municipal wastewater treatment plants. Depending on the sensitivity of the receiving water, the plant may need to meet Class I-A, I-B, or Class II standards.
For plants serving around 90,000 people, secondary biological treatment is standard, often including activated sludge processes. Many plants also incorporate nutrient removal (nitrogen and phosphorus) to meet stricter effluent standards, especially if discharging into sensitive water bodies.
