摘要
内蒙古自治区得天独厚的煤炭储量以及相对丰富的土地资源,使得煤化工项目在内蒙古自治区得到了前所未有的发展。同时内蒙古自治区有限的水资源和煤化工废水排放的最终去向,成为大型煤化工项目的发展瓶颈。本文以某大型煤化工项目的污水处理为例,对缺水地区大型煤化工项目污水的处理工艺和最终去向进行讨论,重点对提高生化系统处理效率的措施进行探讨。该项目采用A/O工艺和BAF工艺对污水进行生化处理,再利用超滤反渗透进行深度处理后,将出水回用于生产过程,是大型煤化工项目在环境保护和节约水资源的有效手段之一。
Inner Mongolia＇s coal reserves are unique and relatively abundant land resources makes the coal chemical projects in Inner Mongolia Autonomous Region has been an unprecedented development, while Inner Mongolia＇s scarce water resources and coal chemical discharges has become a serious constraint large-scale coal chemical projects bottleneck. In this paper, taking the sewage treatment of a large-scale coal chemical project for example, the author discusses sewage treatment process and the final destination of a large-scale coal chemical project in dry land, and the main purpose is to discuss how to improve the efficiency of the biological process. The project uses the A / 0 process and BAF process on biological sewage treatment, after depth treatment by ultra filtration and reverse osmosis, the water will be back in the production process, rather than outward emissions, it is conducive to environmental protection and conservation of water resources.
