为了应对新的饮用水水质标准,传统的共沉积、离子交换、膜处理、电絮凝、吸附等技术取得了新的进展。通过回顾这些新技术采用的新材料及工艺研究的现状,分析了其处理含砷(Ⅲ)水质的局限性。新材料的稳定性、高选择性、廉价性是未来新技术研究与开发值得关注的重要研究方向。
To answer for the new water quality standard, new progress was made in traditional technologies including coprecipitation, ion exchange, membrane process, electrocoagulation and adsorption. By reviewing the new advances, limitation in treatment of water containing As( Ⅲ ) was analyzed. Stability of materials, higher selectivity and cost effectiveness should be mainly considered in future study.
