摘要
水资源短缺被认为是对人类活动目前和未来的威胁,因此净水技术在世界范围内受到了广泛关注。纳米技术近年来在废水处理的领域发展迅速,利用纳米材料独特的物理化学性质产生的催化氧化性、吸附性去除废水中的污染物,光催化纳米技术的应用越来越普遍。本文综述了光催化降解污染的原理,以及近年来光催化纳米材料处理富含重金属离子、有机化合物和无机化合物的各种工业废水的应用,期待开发更多高效光催化纳米材料和净水工艺。
Water scarcity is considered to be a current and future threat to human activities,and therefore water purification technologies have received a lot of attention worldwide.Nanotechnology has been developing rapidly in the field of wastewater treatment in recent years,and the application of photocatalytic nanotechnology is becoming more and more common by using the catalytic oxidative and adsorptive properties of nanomaterials arising from their unique physicochemical properties to remove pollutants from wastewater.The principles of photocatalytic degradation of pollution and the applications of photocatalyticnanomaterials for treating various industrial wastewaters rich in heavy metal ions,organic and inorganic compounds in recent yearswere reviewed,in anticipation of the development of more efficient photocatalyticnanomaterials and water purification processes.
