膜领域国家自然科学基金资助的印迹（2000-2019）：回顾与展望

 对2000-2019年国家自然科学基金（NSFC）资助的膜分离项目进行统计，并对获得资助的项目类别、项目名称、项目负责人、经费数额、依托单位、地区进行分析，结果表明：（1）NSFC在膜分离领域共资助项目920项，累计资助经费达54684万元，项目资助数量和经费均呈现逐年增长的趋势。（2）北京、江苏、天津、浙江和辽宁是我国5大膜分离研究区域。（3）超滤、纳滤、反渗透和正渗透等膜法水处理技术在2010年后的立项数及经费快速上升，而膜反应器领域增长较为缓慢。（4）从重点项目和重大项目来看，近些年研究方向主要集中于气体分离领域中氢气膜分离技术和二氧化碳膜分离技术、水处理膜领域中膜法饮用水处理和污水再生技术等研究。

Imprints funded by the National Natural Science Foundation of China in the field of membranes (2000-2019): Retrospect and Prospect

This paper makes a statistical analysis of the membrane separation projects funded by the National Natural Science Foundation of China (NSFC) from 2000 to 2019, including the types of the projects funded, the project names, the leading scholars of the projects, the amounts of funds, the supporting entities, and the regions of the related research groups. It is shown that during these 20 years:(1) the NSFC has funded 920 projects in the field of the membrane separation, with a total funding of 54,684 million yuan, and the number and the funding of the projects have shown an increasing trend year by year. (2) Beijing, Jiangsu, Tianjin, Zhejiang and Liaoning are the five major membrane separation research areas in China. (3) The number of projects and the funding for the membrane water treatment technologies, such as the ultrafiltration, the nanofiltration, the reverse osmosis and the forward osmosis, have increased rapidly after 2010, while the growth of the membrane reactors is relatively slow. (4) From the perspective of the key projects and the major projects, the research directions in recent years have mainly focused on the hydrogen membrane separation technology and the carbon dioxide membrane separation technology in the gas separation field, and on the drinking water treatment and the wastewater regeneration technology in the water treatment field.
