一种饮用水安全保障新技术:微纳米气泡
A New Technology for Drinking Water Safety:Micro-Nano Bubbles
摘要
Abstract
[Objective]At present,the issues of water resource security and quality are becoming increasingly prominent.Especially against the backdrop of the accelerated urbanization process,ensuring the safety of drinking water is particularly important.The micro-nano bubbles(MNBs)technology(bubbles with diameters ranging from 0.001 μm to 100.000 μm are called MNBs),with its unique physicochemical properties and multi-mechanism synergy effects,has shown significant potential for pollution control and system optimization,and has gradually become an important means to ensure the safety of drinking water.[Methods]MNBs in water can be generated through various methods,such as mechanical shearing and ultrasonic cavitation,which can effectively produce a large amount of MNBs.The uniqueness of MNBs lies in its extremely high specific surface area in water(up to 3 000 m2/m3),extremely long lifespan(existence time can last for several weeks),and high mass transfer efficiency.In addition,MNBs can generate a large number of free radicals in water,especially the generation of hydroxyl radicals(·OH)is from 5 times to 10 times that of ozone,which gives them a significant advantage in the oxidation and decomposition of organic pollutants.This powerful oxidation capacity enables the MNBs technology to demonstrate unique application value in water quality improvement.[Results]In practical applications of water quality improvement,MNB technology is not isolated;it is often combined with traditional chlorine disinfection,ultraviolet disinfection,membrane filtration,and other technologies to form a synergistic effect.This combination not only reconfigures the treatment process of water treatment plants but also effectively inhibits the formation of biofilms in the distribution network,thereby improving the overall efficiency of the water supply system.Moreover,MNBs have the ability to dynamically regulate water quality,adjusting treatment strategies in real time according to changes in water quality,ensuring the safety and health of water quality.[Conclusion]In the process of promoting the transformation of water supply systems towards low-carbon and green,MNB technology is expected to become the core solution for drinking water safety.By reducing reliance on traditional chemical agents and lowering energy consumption in the water treatment process,this technology not only enhances the efficiency of water treatment but also has a positive impact on environmental protection,making significant contributions to achieving safe,healthy,and sustainable drinking water supply.关键词
