粘胶纤维生产中回收芒硝的综合利用

对某黏胶纤维生产企业的废水进行分析及综合处理,从而开发出各种废气处理技术,以期以较低的设备投资,较少的原辅材料投入和运行成本,清除废水中的有害物质,使之变成可以重复利用的原料己经提到了黏胶纤维工厂的紧迫日程.通过工艺比较,最后得到最佳方案为从废水中回收芒硝,再用芒硝制备烧碱.国内外已有这个方向的研究,理论上和实验所改进的工艺设施都是可行的,操作简单、运行可靠、自动化程度高,且等于企业大范围治理、生产.实验在芒硝制烧碱过程中的关键是加入了碳酸氢钠,大大提高了烧碱的转化率.

Viscose fiber production in the recovery of the comprehensive utilization of Glauber's salt

Wastewater of a business analysis and integrated manner, in order to develop all kinds of exhaust gas treatment technology, with a view to a lower investment in equipment, raw and auxiliary materials, less investment and operating costs, removal of harmful substances in waste water to make it into a you can re-use of raw materials, the subject has been referred to the urgent agenda viscose fiber plant, through the process of comparison, the last to be the best option for the recovery from wastewater Glauber's salt, and then preparation of caustic soda, Glauber's salt. At home and abroad have done the previous research in this direction is theoretically feasible, and laboratory facilities, improving the process are feasible, simple operation, reliable operation and high degree of automation for a wide range of corporate governance, production is feasible. The experiment system of caustic soda in the process of Glauber's salt key point is the inclusion of sodium bicarbonate, sodium bicarbonate accession greatly improved the conversion rate of caustic soda.
