曲久辉院士、赫尔曼院士等人撰文回顾汤院士环境水质学学术思想

我国著名环境工程学家、环境水质学学科创始人、中国工程院院士汤鸿霄先生于2022年12月16日因病在北京逝世。

汤鸿霄先生曾长期担任《环境科学学报》主编（1996-2015年），十分关心学报发展，对学报的发展壮大作出了不可磨灭的贡献。

为了表达对汤先生的深切缅怀，《环境科学学报》在汤先生逝世周年之际，出版了这本由国内外环境水质学及相关研究领域专家学者撰稿的《汤鸿霄环境水质学学术思想研讨专刊》。

主编曲久辉院士和汤先生的生前好友德国科学与工程院Hermann H. Hahn院士专门为专刊作序。

汤鸿霄先生的学术思想博大精深。专刊既有顶层设计，更有业界同行和先生弟子们的自由选题，客观地反映出先生学术思想的方向引领性、技术指导性和影响广泛性。专刊选题覆盖广泛、特色鲜明，是对先生学术思想的借鉴、继承和发扬。

首先，聚焦了水质安全与风险防控。汤先生是环境水质学的创始人，水质安全是专刊研讨的核心问题。这不仅体现在针对饮用水嗅味、消毒副产物、色度浊度等安全问题的关注上，也体现在利用混凝吸附、高级氧化、超声辐照等物化技术对污废水进行解毒降毒从而防范风险上。

第二，体现了系统治水的思想方法。汤先生早期研究即注重用水废水统筹，而且一直系统地致力于水质控制技术创新和环境水质过程理论创新。专刊系统地涵盖统筹了废水、污水、饮用水、雨水、水环境，传统污染物和新污染物，污染问题和气候变化，水污染、水环境、水生态乃至水经济等，体现了水的系统治理。

第三，体现了技术特色和创新发展。汤先生是化学水处理的国际领军科学家，利用物化技术进行强化预处理和深度处理，不仅对水质保障十分重要，而且面对减污降碳和微塑料等新污染物治理，物化水处理技术更加展现出其不可替代的作用，更需要创新发展，专刊很好地体现了这一特色和趋势。

汤先生学术思想历久弥新，在新时代依然闪耀着学术的光芒，值得不断学习研究和继承发扬。

感谢所有的作者对专刊的支持！特别感谢马军院士、王晓昌教授、孟晓光教授、郑怀礼教授、王建龙教授、韦朝海教授、杨敏研究员等专家为专刊供稿！

感谢特邀学术编辑杨敏研究员、王东升教授、刘锐平教授、祝贵兵研究员、石宝友研究员、胡勇有教授、宋永会研究员、王毅力教授、晏明全教授、冯成洪教授对专刊组稿审稿工作的大力支持和帮助！

谨以此专刊纪念我们敬爱的汤鸿霄先生！

Professor Hongxiao Tang, internationally respected and admired

Hongxiao Tang， much admired water scientist and loved teacher， member of the Chinese Academy of Engineering， as well as author of many impact generating publications， has passed away in his 91st year. The international community of scientists， not only of water scientists， has lost one of its foremost leaders and beacons. To many of the members of this community he was not only a beloved teacher to his numerous students but turned to be a mentor to a large community in the truest sense of the world.

Many of us were lucky to meet him in person and were deeply impressed by his command of his and our field， water， understanding， furthering and protecting this live-guaranteeing resource. By his traveling， which to him was not always easy， he met his former students， members of his world-wide network of colleagues and formed new contacts. These colleagues will in commemorative publications describe his specific areas of work， his significant contributions and his inspiring ideas in more detail. For me it suffices to say that Professor Tang─as we all called him in deep admiration and veneration， provided ideas for present and future work and helped to build bridges between neighboring disciplines， bridges between fields and also bridges over- not only - national or continental gulfs.

Professor Tang’s interest and later his contributions as well as his support to the international symposia series of the Gothenburg Symposia exemplified his broad field of scientific interest as well as his commitment to his science and the necessary technology transfer. The original thrust of those symposia was to get practitioners and scientists of water technology， in particular water treatment technology， together on a regular basis. And by this he not only disseminated knowledge， newly gained knowledge， but also raised interest on this frequently underestimated and overlooked field of water technology. Hongxiao Tang， due to his very successful own work on water chemicals in all their forms became a true frontman for these symposia. He gave substance and weight to a field of treatment that had been for a long time in the shadow of other technologies， those more biochemical treatment processes of water.

To us， who knew him， to us who learned from him， to us whom he inspired， we all owe him a continuation of his work as an outstanding teacher， as a bridge builder over many disciplines and as catalyst for technology transfer.
