  • 摘要:我公司研发、生产的脱硫废水零排放新工艺,采用多种技术、工艺,减少废水外排对环境造成的污染,真正实现零排放。详情请致电:400-0319-806 。

           脱硫废水零排放新工艺包括脱硫废水的预处理技术、浓缩减量技术和固化处理技术。详细介绍了脱硫废水零排放甘肃11选5技术,并对目前脱硫废水零排放技术在研究和应用中存在的问题进行了探讨。 随着水处理技术的发展,燃煤电厂的绝大部分废水能够实现阶梯利用,但脱硫废水是电厂终端废水,悬浮物高、含盐量高、硬度高、腐蚀性强,难以直接回用。随着环保力度的加大,很多地方环保局要求电厂废水零排放。因此,采用适合的技术实现脱硫废水零排放是迫切和必要的。
