污水灌溉的现状与展望

Situation and Prospect of Sewage Irrigation in Agriculture

水污染问题是当前农业发展亟待解决的问题。利用污水进行污水回灌农田是一种低费用、低能耗的污水处理途径,也是保障水资源可持续利用的有效措施之一。本文在简要回顾国内外污水回用灌溉农田的历史和发展现状的基础上,总结了污水灌溉在理论研究、技术研究等方面取得的主要成果,并针对我国污水灌溉中存在的问题,指出了目前和未来该领域研究的重点,以期推动污水灌溉的规范化、科学化、健康化发展。

Water pollution has been a serious strain to agriculture production in China for a long time. Sewage irrigation is not only a low cost and low energy-consuming way in dealing with polluted water, but also an effective way for sustainable utilization of water resource. In this paper, the history and current situation of sewage irrigation in the world were reviewed and analyzed, the main achievements in theories and techniques of swage irrigation were summarized, the current and future research emphases were disclosed according to problems of swage irrigation in China. It is hoped to promote the development of swage irrigation in China in a standard, scientific and healthy way.
