摘要
传统的废水处理技术面临着系统繁杂,运行费用高、易结垢和腐蚀等问题,因此需要采用一种一体化的多功能耦合系统,兼顾除盐、防垢等功能,用以除去废水中的污染物。电吸附技术是一种可实现水的净化、淡化的新型水处理技术,可在低能耗的前提下有效去除水中的杂质离子而不结垢。综述了电吸附理论的发展沿革、电吸附原理和双电层理论要点、电吸附结构及其工作流程等,介绍了几种主要的电吸附材料及其优缺点。基于日趋严格的环保要求,电吸附技术以其低能耗、低成本、无二次污染等优势,可望在电力行业得到较广泛的应用。
Traditional water treatment technology is still faced with many problems,such as complex system,high operating cost,easy scaling and corrosion.Therefore,it is necessary to adopt an integrated multi-functional coupling system,which can take into account the functions of desalination and anti-scaling to remove the pollutants in the wastewater.Electro-sorption technology is a new water treatment technology for water purification and desalination,which can effectively remove impurity ions from water without scaling under the premise of low energy consumption.In this paper,it was summarized the development history of electro-sorption theory,the principle of electro-sorption and the main points of electric double layer theory,the structure of electro-sorption and its working process,etc.At the same time,several main electro-sorption materials and their advantages and disadvantages were introduced.Based on increasingly strict environmental protection requirements,electro-sorption technology is expected to be widely used and developed in the power industry due to its technical advantages such as low energy consumption,low cost and no secondary pollution.
