贝壳在工业废水处理工艺应用的研究进展
Research Progress on Application of Shells in Industrial Waste water Treatment Process
摘要
Abstract
[Objective]With the vigorous development of the social economy,wastewater generated from industries such as smelting,mining,electroplating,leather making,printing,and dyeing is a serious challenge for environmental governance.Shell is a natural biomass of calcium carbonate,which has attracted widespread attention in the field of industrial wastewater treatment due to its unique organic-inorganic composite structure and physicochemical properties.[Methods]This paper reviews the pollution sources such as heavy metal ions and organic pollutant in industrial wastewater,elaborates on the mechanisms and main influencing factors of adsorption,photocatalytic degradation,chemical precipitation,and biodegradation process,and explores the application of shell materials in different treatment process.[Results]In addition,the high efficiency of shell as an adsorbent material for the removal of heavy metal ions and organic pollutant in industrial wastewater,the adaptability of shell-based carriers in photocatalytic degradation of organic pollutant,and the stability of shell-based carriers in chemical precipitation and biodegradation process is explored.Finally,the mechanism of physical and chemical modification to regulate the properties of shell-based materials is elaborated systematically.Combined with the analysis of reaction kinetics,adsorption isotherms,microstructure,and thermogravimetry,the reaction mechanisms of surface adsorption,ion exchange,and catalytic degradation are summarized,which is of great significance for exploring the process of shell resource utilization.[Conclusion]At present,the research on the removal of water pollutants by shells is still in the exploratory stage and has not yet formed an industrialized application technology system.The research on the secondary dissolution and recycling of heavy metal ions and organic pollutants in shell materials still needs more breakthroughs and development.关键词
