On the outside of the cavity, a supplementing mechanism can allow the precipitant to enter the interior of the cavity from multiple directions and from the outside to the inside to mix with the waste liquid, thereby greatly improving the treatment efficiency of the waste liquid. The mixing mechanism can stir the mixed liquid to improve the treatment effect of the waste liquid. The mixed liquid is a mixed liquid of copper ion micro-etching waste liquid and a precipitant. The connecting mechanism is used to introduce the mixed liquid in the cavity into the filter box 16, and the solid particles in the mixed liquid are collected through the filter box 16.

[0024] In this embodiment, at least four groups of pre-loading tanks 4 are arranged on the middle section 1 of the container. The precipitant in the pre-loading tank 4 is transported through the discharge tank 5, and the precipitant is introduced into the pre-loading tank 4 through the loading pipe 11 to precipitate copper ions from the copper ion-containing micro-etching waste liquid.

[0025] See also Figures 1 to 4 The mixing mechanism includes a motor 6 fixedly mounted on the top of the container top section 3, an output end of the motor 6 extends to the interior of the container middle section 1 and is fixedly connected to a stirring rod 7, and stirring blades 8 are evenly mounted on the stirring rod 7.

When the standing is completed, the solenoid valve 13 is opened to allow the mixed liquid inside the cavity to flow into the first delivery pipe 12. The mixed liquid is a liquid formed by mixing the copper ion micro-etching waste liquid with the precipitant;

[0029] The delivery pump 14 is turned on. The delivery pump 14 pumps the mixed liquid in the first delivery pipe 12 from the first delivery pipe 12 into the second delivery pipe 15, and enters the interior of the filter box 16 through the second delivery pipe 15. After the mixed liquid enters the interior of the filter box 16, it comes to the inner side of the loading rack 21, and the solid particles in the mixed liquid are filtered through the filter screen 23 on the loading rack 21, so that the solid particles remain on the upper surface of the filter screen 23. In this device, the loading rack 21 and the filter screen 23 are set in two groups to achieve multi-layer filtration. The filtered mixed liquid is guided by the guide plate 20. Since the guide plate 20 is inclined and the end of the guide plate 20 extends to the inner side of the waste processing pipe 18, the cleaned mixed liquid remains in the waste processing pipe 18, so that the fixed particles are cleaned in the waste processing pipe 18.

[0030] This device has the advantages of simple operation and high processing efficiency: in the process of mixing the waste liquid with the precipitant, the precipitant can flow from the outside to the inside of the cavity in multiple directions and mix with the waste liquid, thereby improving the processing efficiency of the waste liquid. The waste liquid is filtered in two layers through the loading rack 21 and the filter screen 23, and then the solid particles in the liquid are collected through the waste processing pipe 18, which makes it more convenient to fix the particles after precipitation.
