News - Case Study on Water Treatment Plant Monitoring in a County of Zunyi City, Guizhou Province

The wastewater treatment plant located in a county of Zunyi City, Guizhou Province, employs an advanced wastewater treatment process. With a designed capacity of 0.5 million cubic meters per day, the facility currently achieves an initial daily treatment volume of 0.15 million cubic meters. The plant was upgraded from an original facility with a capacity of 1,500 m³/d, and now complies with Grade A discharge standards specified in the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" (GB 18918-2002). Upon full operation, this plant is expected to significantly improve the local aquatic environment and play a crucial role in water pollution control, protection of river water quality, and maintenance of ecological balance.

At the effluent outlet of the wastewater treatment plant, online monitoring instruments for COD, ammonia nitrogen, total phosphorus, and total nitrogen—along with industrial pH and dissolved oxygen meters—have been installed. These devices enable real-time monitoring of key operational parameters, providing timely data alerts and early warnings to ensure the stable and efficient performance of the treatment system. Furthermore, the integration of automated instrumentation enhances operational control and efficiency. Through data-driven process optimization, the system reduces reliance on manual labor, minimizes human error, and lowers operational costs. Real-time monitoring and feedback mechanisms also contribute to the prevention and prompt resolution of potential pollution incidents, thereby reducing environmental and safety risks.
