摘要： 本文对木材净水器“神奇变身术”包含的碳化、亲水过程及其净水效果和原理进行了介绍。木材净水器能有效去除水中较大粒径(≥ 10 μm)的微塑料、有机染料、抗生素等污染物，且能实现对南京市玄武湖天然水样的净化。借助实物演示、宣传牌和视频展示、抽奖问答等环节实现了公众参与和趣味科普。以此，为化学科普教育提供了新的实践范例。

关键词: 木材, 碳化, 亲水性处理, 净水

Abstract: This paper elucidates the carbonization and hydrophilization processes involved in the “magic transformation” of wood into a water purifier, along with its purification efficacy and underlying mechanisms. The wood-based purifier effectively removes contaminants such as microplastics (≥ 10 μm), organic dyes, and antibiotics from water, demonstrating successful purification of natural water samples from Nanjing’s Xuanwu Lake. Through hands-on demonstrations, informational displays, video presentations, and interactive quiz sessions, this project achieved public engagement and delivered accessible science communication. The study presents a novel practical model for chemical science education.

Key words: Wood, Carbonization, Hydrophilic treatment, Water purification
