7. The apparatus for treating waste liquid in PCB production process according to claim 1, wherein: six groups of stirring blades (4) are uniformly installed on the outer side of the connecting shaft (5), and stirring rods (16) are uniformly installed on the outer side of the rotating shaft (10).

8. The apparatus for treating waste liquid in PCB production process according to claim 1, wherein: transmission (6) include second belt pulley and second driving belt, connecting axle (5) and axis of rotation (10) are kept away from the one end of advancing feed bin (23) and are extended to the outside of transition bin (7) and all install the second belt pulley, and the outside of two sets of second belt pulleys is provided with second driving belt jointly.

9. The apparatus for treating waste liquid in PCB production process according to claim 1, wherein: three way connection (25) with drainage funnel (20) bottom intercommunication are installed to one side of feed inlet and discharge storehouse (23) bottom, valve (26) are all installed to two sets of outputs of three way connection (25), and the one end intercommunication that the top is close to feed inlet and discharge storehouse (23) in the output of a set of valve (26) and waste material discharge pipe (28).

10. A method for treating a waste liquid treatment device in a PCB production process according to any of claims 1-9, comprising the steps of:

1. firstly, when waste liquid is continuously poured into the feeding hopper (13), chemical agents with corresponding amount are continuously poured into the first cylindrical frame (103) at the same time, the control panel (17) controls the driving device (101) to drive the rotating rod (104) and the first cylindrical frame (103) to rotate at a constant speed, so that the waste liquid and the chemical agents are mixed with each other, and precipitates are gradually generated;

2. then, the first servo motor (8) is controlled to drive the connecting shaft (5) to rotate, the connecting shaft (5) drives the spiral stirring paddle (9) and the rotating shaft (10) to rotate through the transmission of the transmission device (6), so that the mixed liquid in the stirring bin (11) is stirred, and the stirred mixed liquid enters the transition bin (7);

3. in the process that the mixed liquid enters the interior of the precipitation bin (3), precipitates in the mixed liquid gradually sink into the four groups of blow-down funnels (14), then waste liquid for separating the precipitates gradually flows into the interior of the drainage funnel (20) through the water outlet (24), the waste liquid is filtered again by the rotating second filter screen (106), and finally the obtained treated waste liquid enters the three-way joint (25) from the bottom end of the drainage funnel (20);

4. at this time, a set of valves (26) away from the second servo motor (27) is opened, so that the treated waste liquid can be discharged, and the first filter screen (105) and the second filter screen (106) are cleaned periodically.
