Water pollution, stemming from various contaminants including organic and pharmaceutical pollutants, poses a significant global challenge. Amidst the array of methods available for pollutant mitigation, the three-dimensional electrochemical approach emerges as a standout solution due to its environmental compatibility, cost-effectiveness, and rapid efficiency. This study delves into the efficacy of three-dimensional electrochemical processes in purging organic and pharmaceutical pollutants from aqueous media. Existing research indicates that the three-dimensional electrochemical process, particularly when employing particle electrodes, exhibits notable success in degrading organic and pharmaceutical pollutants. This achievement is largely attributed to the ample specific surface area of particle electrodes and the shortened mass transfer distance, which collectively enhance efficiency in comparison to traditional two-dimensional electrochemical methods. Moreover, this approach is lauded for its environmental friendliness and cost-effectiveness. However, it is imperative to note that the efficacy of the process is subject to various factors including temperature, pH levels, and current intensity. While the addition of oxidants can augment process efficiency, it also carries the risk of generating intermediate compounds that impede the reaction. In conclusion, the three-dimensional electrochemical method proves to be a viable and practical approach, provided that process conditions are meticulously considered and adhered to. Offering advantages from both environmental and economic perspectives, this method presents a promising alternative to conventional water and wastewater treatment techniques.
水污染源于各种污染物，包括有机污染物和药物污染物，是一个全球性的重大挑战。在现有的各种污染物减排方法中，三维电化学方法因其环境兼容性、成本效益和快速效率而成为一种突出的解决方案。本研究探讨了三维电化学工艺在净化水介质中有机和药物污染物方面的效果。现有研究表明，三维电化学工艺，特别是采用颗粒电极时，在降解有机和药物污染物方面取得了显著的成功。这主要归因于颗粒电极具有较大的比表面积和较短的传质距离，与传统二维电化学方法相比，其效率得到了显著提高。此外，这种方法还因其环境友好性和成本效益而受到赞誉。然而，必须指出的是，该过程的效率受到各种因素的影响，包括温度、pH 值和电流强度。虽然添加氧化剂可以提高处理效率，但也会产生阻碍反应的中间化合物的风险。总之，只要仔细考虑和遵守处理条件，三维电化学方法就是一种可行且实用的方法。从环境和经济的角度来看，该方法为传统的水和废水处理技术提供了一种很有前途的替代方法。
