摘　　要：新疆塔里木盆地地区在长期的地质作用和现代农业土地管理下,产生了大量的盐碱水,分布广、污染严重,对当地生态环境和经济发展不利。针对高矿化度、高离子系数的盐碱水,国内外已经取得规模化应用的淡化技术主要有多级闪蒸、低温多效蒸馏、反渗透、超滤、电渗析等,技术理论基础可靠,应用效果显著。解决现有技术的腐蚀问题,研发太阳能等清洁能源集成技术,拓展微咸水利用途径,是未来利用盐碱水的主要发展方向。Under the long-term geological effect and modern agricultural land management,Xinjiang Tarim Basin has produced a large number of saline-alkali water,which is widely distributed and seriously polluted,and is detrimental to the local ecological environment and economic development.For saline-alkali water with high salinity and high ionic coefficient,the desalination technologies that have been widely used in China and abroad mainly include multi-stage flash distillation,low-temperature multi-effect distillation,reverse osmosis,ultrafiltration and electrodialysis.The theoretical basis of the technology is reliable and the application effect is significant.Solving the corrosion problem of existing technologies,developing clean energy integration technologies such as solar energy and expanding the utilization way of brackish water are the main development directions of saline-alkali water utilization in the future.
