工业废水通过前置输水单元进行收集后通过抽水管道9输送至喷射单元，喷射单元将工业废水喷射成一定厚度以及一定宽度的水幕8，此时电子加速器19产生的电子束1通过扫描钛窗4与辐照保护单元照射在水幕8上，废水周转单元接收到被辐照过的工业废水并输送至后置收集单元进行后序处理。
如图2和图3所示废水周转单元包括废水周转箱2、位于废水周转箱2上方的扫描窗口6以及与后置收集单元连通的出水口；辐照保护单元包括位于扫描窗口6的保护膜保持框71以及固定于保护膜保持框71内的保护膜72(如图7所示)；保护膜72采用钛箔或者耐辐射的隔离膜， 钛箔的厚度控制在0.02mm～0.05mm；隔离膜采用聚酰亚胺材料制作而成，其厚度控制在0.05mm～0.15mm。
前置输水单元包括用于收集工业废水的工业废水池17以及位于工业废水池17底部的输水口，输水口通过抽水管道9与喷射单元连通，同时在抽水管道9上设置可控水泵11以及流量控制器10用于控制工业废水的流速以及流量。该系统还包括一控制单元20，控制单元20与可控水泵11以及流量控制器10连接，实现自动控制，可以根据电子加速器19的辐照能量、束流大小控制工业废水的流速以及流量，提高工业废水的处理效果。

基于上述系统结构，在使用中，扫描钛窗4上的钛箔以及保护膜保持框71的保护膜72由于电子束1的辐射会发热，为了能够给其迅速降温，在扫描钛窗4与保护膜72之间通过冷却装置进行冷却，如图2和图3所示冷却装置包括冷却风道13、位于扫描钛窗4与保护膜72一侧的冷却风嘴14，冷却风嘴14直接将冷风吹在扫描钛窗4的钛箔以及保护膜72上；同时在扫描钛窗4与保护膜72另一侧设置弧形导风板15；冷风从冷却风道13通过冷却风嘴14吹在扫描钛窗4上的钛箔上，之后经过弧形导风板15导流到保护膜保持框71内的保护膜72上对其冷却，能够延长钛箔以及保护膜72的使用寿命。
该系统的控制单元20可以与生产主控制系统21进行匹配后集中控制；生产主控制系统21可以根据当前电子加速器19运行的能量、束流大小来发送指令控制可变口径的喷嘴3来调节出水口的大小，从而控制喷射的水幕8的厚度，控制可控水泵11调节喷嘴3出水流速，从而实现辐照废水处理时的水幕8厚度、流速跟随电子束1能量、束流的变化而调节，保证废水辐照处理的剂量吸收的一致性。
