摘　　要：激光空化降解技术是一种先进的环境修复技术,是利用激光产生的高能量脉冲在液体介质中诱导空化现象,从而实现对有机污染物的有效降解。然而,该技术的实施效率受多种因素影响,包括激光的强度、脉冲宽度、介质性质等,这些因素共同决定了降解过程的效果与效率。文章详细探讨了激光空化降解技术的基本原理、技术优势与面临的挑战,提出了针对性的监测理论与方法,通过实验研究验证了激光参数以及有机污染物介质性质对激光空化降解效率的影响,并通过优化实验参数,提高了降解效率,为激光空化降解技术的应用提供了理论基础和实验支持。Laser cavitation degradation technology is an advanced environmental remediation technology,which uses the high energy pulse generated by laser to induce cavitation phenomenon in the liquid medium,so as to achieve effective degradation of organic pollutants.However,the implementation efficiency of this technology is affected by many factors,including the intensity of the laser,the pulse width and the nature of the medium,which together determine the effect and efficiency of the degradation process.In this paper,the basic principle,technical advantages and challenges of laser cavitation degradation technology are discussed in detail,and targeted monitoring theories and methods are proposed.Experimental studies have verified the influence of laser parameters and the properties of organic pollutant media on laser cavitation degradation efficiency,and the degradation efficiency is improved by optimizing experimental parameters.It provides theoretical basis and experimental support for the application of laser cavitation degradation technology.
