Embodiment Construction
[0068] Please refer to Figure 1 to Figure 7 As shown, it shows the specific structure of a preferred embodiment of the present invention, including a pre-plating treatment device 10 , a collection tank 20 , a vibrating membrane ultrafiltration device (UF) 30 and an intermediate tank 40 .
[0069] Among them, such as figure 1 As shown, the electroplating pretreatment device 10 is used for surface decoration (such as polishing, rolling, embossing, etc.) A large amount of degreasing effluent, dewaxing effluent and cleaning effluent.
[0070] The collection pool 20 is used to collect the oil-removing sewage, wax-removing sewage and cleaning sewage output from the electroplating pretreatment device 10 , and the input port of the collection pool 20 communicates with the output port of the aforementioned electroplating pretreatment device 10 .
[0071] The vibrating membrane ultrafiltration device (UF) 30 is used to filter and separate the sewage output from the collection tank 20...
