Application of digital twin in biological slow sand filtration technology in rural water supply projects
Under the new situation,China has vigorously promoted the application of digital twin technology in the manage-ment of rural water supply projects.Farmers in hilly and mountainous areas in southwest China live in scattered areas with diverse water sources.Biological slow sand filtration technology is widely used because of its simple structure and strong adaptability to water quality.However,problems in daily operation such as not timely maintenance and failure to accurately judge whether the water is up to standard pose a threat to water supply safety.Digital twin technology was adopted in biolog-ical slow sand filtration.Monitoring equipment was installed at key nodes to monitor the turbidity,filtration speed,water quality and other parameters of water supply.Wireless remote sensing terminals collected the monitoring data and transmit-ted them to the data analysis system.In case of real-time data exceeding the threshold,an alarm is issued to notify the water management personnel to conduct on-site inspections.The results of practice in the Shuitianba Township project in Zigui County showed that the smart transformation of the rural water supply project can change the traditional onsite manage-ment by people,reduce the work pressure of water managers,and ensure the quality of water supplied.Viewing from the effects,the application of digital twin in biological slow sand filtration was a beneficial attempt for smart water supply in ru-ral areas.
