摘要
随着城市化进程加快,城市需水量日渐增加,资源型与水质型缺水城市越来越多。膜分离技术的发展使小系统局部循环利用水资源的模式成为可能,这种水资源利用方式延长了水资源的生命周期,能帮助城市从根本上解决水资源总量短缺的问题。通过延长水的生命周期来缓解城市水资源短缺是迫切而具有现实意义的举措。目前,膜技术的使用已给北京、山东、江苏等地带来明显的效益,在一定程度上缓解了水资源短缺问题。
With rapid urbanization, water demand is increasing day by day, and more and more cities are facing water shortage because of resource and water quality problems. The development of mem- brane separation technology makes the cyclic utilization mode of water resource locally in small system possible. This utilization mode extends the life-cycle of water resources and becomes a fundamental solu- tion to the water resources shortage. Easing urban water resources shortage by extending the life-cycle of water resources is an urgent action with practical significance. At present, the application of membrane technology has already brought obvious benefit to Beijing, Shandong and Jiangsu, and eased the water resources shortage problem to a certain extent.
