description The invention discloses a treatment method for wastewater produced in a PCB production process. The treatment method is characterized by comprising the following steps: S1, pretreatment; S2, photocatalytic treatment; S3, filtering and impurity removal; and S4, nanofiltration membrane treatment. The treatment method for wastewater produced in the PCB production process disclosed by the invention can rapidly, efficiently and safely treat the wastewater produced in the PCB production process, is simple in treatment process, convenient to operate, free of secondary pollution, low in equipment investment and energy consumption, remarkable in wastewater treatment effect, high in efficiency and suitable for continuous large-scale production, and has high economic values and social values. 本发明公开了一种PCB生产过程中废水处理方法，其特征在于，包括如下步骤：步骤S1、预处理；步骤S2、光催化处理；步骤S3、过滤除杂；步骤S4、纳滤膜处理。本发明公开的PCB生产过程中废水处理方法，该处理方法能快捷、高效、安全地对PCB生产过程中废水进行处理，处理工艺简单，操作方便，不会产生二次污染，设备投入小，耗能低，废水处理效果显著，效率高，适合连续规模化生产，具有较高的经济价值和社会价值。
