木质活性炭和颗粒活性炭滤水哪个较适合?

  木质活性炭和颗粒活性炭滤水哪个较适合?根据其外观,活性炭可分为颗粒碳(GAC)和粉状碳(PAC)。颗粒碳主要用于水的先进处理,处理方法一般是颗粒活性炭过滤床过滤。吸附饱和一段时间后,活性炭再生并再利用。粉主要用于水的预处理。例如,在凝结过程中将其添加到水中。有机物在水中被吸收后,与降水过程中的明花一起从水中去除。粉是一次性的,不会再生。与粉状碳相比,颗粒碳过滤具有稳定的处理效果和良好的排污质量。饱和活性炭可以以较低的运行成本再生和再利用。因此,颗粒碳吸附技术常用于水厂。颗粒碳的缺点是它只需要一个碳过滤器或过滤器,设备投资高于粉状碳。

  颗粒活性炭吸附是在常规处理的基础上,从水中去除有机污染物的有效、先进的水处理技术。早在20世纪50年代初,西欧和美国的一些地表水工厂就开始使用活性炭去除水中的色和气味。迄今为止,西欧绝大多数以地表水为水源的水厂仍然使用活性炭吸附来去除水中的微量有机污染物、颜色和气味。对于需要长期吸附操作的水厂,颗粒碳通常用于过滤,而粉状碳主要用于季节性配给场所。从20世纪70年代末到80年代初,我国一些水利工程采用了先进的颗粒活性炭吸附处理技术。
