Using intelligent water purification and ecological conservation system to improve environmental conservation benefits evaluation

This study introduces an innovative Intelligent Water Purification and Ecological Conservation (IWPEC) system, which integrates Internet of Things (IoT) technology, solar energy, and artificial floating island technology to address water pollution and ecological conservation. The experimental study was conducted at Qilin Lake in Nantou County, Taiwan, comparing the IWPEC system with traditional artificial floating islands in terms of water quality improvement, biodiversity enhancement, and microbial purification efficiency. Results showed that the IWPEC system achieved a 96 % reduction in total phosphorus (TP) and an 86 % reduction in ammonia nitrogen (NH3-N) and nitrite nitrogen (NOS-N), significantly outperforming the control group. Microbial purification efficiency was 1.37 times higher than that of the control, while biodiversity increased by 25 % during the day and 26 % at night. Additionally, the system's 24-hour real-time monitoring and automated operation allowed it to adapt to climatic and environmental changes. The findings demonstrate the versatility and scalability of the IWPEC system for water purification and ecological conservation, supporting the achievement of the United Nations Sustainable Development Goals (SDG 6: Clean Water and Sanitation, and SDG 13: Climate Action). Future research should explore the scalability of the IWPEC system in larger water bodies and assess its long-term performance and economic feasibility to promote sustainable water resource management.
