1、喷淋洗涤塔结构与工作原理
喷淋洗涤塔主要由主筒体、上部喷淋盘、中部填料、下部喷淋盘、清理孔、视镜孔等组成,其工作原理是:在引风机的负压作用下,废气气流被吸入进风管道并送入塔体。塔的主体是一个圆形筒体,洗涤液(氢氧化钠溶液)从洗涤塔上部喷淋盘射入筒内,使整个筒体的填料与水混合形成雾状洗涤液水膜从上而下流动(填料在气流的作用下不停翻滚,使废气与洗涤液充分混合)。在负压的作用下废气在筒体内旋转上升,并始终与筒体内的洗涤液水膜发生摩擦,这样酸性气体被洗涤液水膜充分湿润、中和。在筒体底部设有清理孔便于进行筒体底部清理,而洗涤液则通过储液箱(水箱)在水泵的作用下不断循环,从而达到消除废气的效果。

2、活性炭的吸附
活性炭的吸附可分为物理吸附和化学吸附。

2.2 化学吸附
除了物理吸附之外,化学反应也经常发生在活性炭的表面。
活性炭不仅含碳,而且在其表面含有少量的化学结合、功能团形式的氧和氢,例如羧基、羟基、酚类、内脂类、醌类、醚类等。这些表面上含有地氧化物或络合物可以与被吸附的物质发生化学反应,从而与被吸附物质结合聚集到活性炭的表面。
活性炭的吸附正是上述二种吸附综合作用的结果。
专业的彩票投注平台 当活性炭在溶液中的吸附速度和解吸速度相等时,即单位时间内活性炭吸附的数量等于解吸的数量时,此时被吸附物质在溶液中的浓度和在活性炭表面的浓度均不再变化,而达到了平衡,则此时的动平衡称为活性炭吸附平衡,此时被吸附物质在溶液中的浓度称为平衡浓度。

无机废水主要含有重金属、重金属络合物、酸碱、氰化物、硫化物、卤素离子以及其他无机离子等。
有机废水含有常用的有机溶剂、有机酸、醚类、多氯联苯、有机磷化合物、酚类、石油类、油脂类物质。相比而言, 有机废水比无机废水污染的范围更广, 带来的危害更严重。
