污水变清流 妙招润绿城

Core Insights - The article highlights the advancements in wastewater treatment technology and the ecological education initiatives at the Jiangnan Water Quality Purification Plant in Nanning, which is the largest of its kind in Guangxi, with a daily wastewater treatment capacity of 720,000 cubic meters, handling about 40% of the urban wastewater in Nanning [1][2]. Group 1: Wastewater Treatment Technology - The Jiangnan Water Quality Purification Plant employs a sophisticated multi-step process including coarse and fine screens, sedimentation tanks, and biological treatment, effectively filtering out large debris and organic matter to produce clear recycled water [2]. - The plant processes approximately 2 million tons of urban wastewater daily, converting it into reclaimed water suitable for various uses such as landscape irrigation, road cleaning, and agricultural irrigation [2]. - An upgrade is underway to introduce a new anaerobic/aerobic/anaerobic/oxidation process, which is expected to increase the plant's capacity to 740,000 cubic meters per day and improve water quality further [2][3]. Group 2: Environmental Education and Recognition - The Jiangnan Water Quality Purification Plant has been recognized as a national benchmark for green and low-carbon wastewater treatment, being the only project in Guangxi to achieve this status [3]. - The facility serves as an educational hub, offering a variety of programs and experiences related to water conservation and environmental awareness, attracting over 4,000 visitors annually [3]. - The plant integrates science education, cultural activities, and community engagement, making it a model for ecological education in Guangxi [3].
