[0029] An integrated multi-stage treatment device for industrial wastewater, the working process is as follows:

[0030] During operation, industrial wastewater enters the filter chamber II 22 through the water inlet I 21. After the wastewater enters, the filter chamber II 22 filters the larger garbage and particulate matter, and the filtered wastewater enters the filter chamber I 23. After the water in the filter chamber I 23 is full, the self-priming pump 25 on the top of the filter chamber I 23 starts to work and sucks the filtered wastewater into the stirring device 3. When there is too much garbage in the filter chamber II 22, the control valve on the slag discharge port I 27 at the bottom of the filter chamber I 23 is opened, and the electric push rod 24 pushes the scraper 26 to slide up and down in the filter chamber II 22 to discharge the garbage in the filter chamber II 22 and clean the garbage attached to the inner wall of the filter chamber II 22, so as to maintain The filter bin II 22 is unobstructed; when the filtered wastewater enters the stirring device 3, the flocculant is put into the raw material bin 33 through the feed port 314. When working, the output end of the motor I 31 drives the raw material bin 33 to rotate, thereby driving the stirring blade 37, the lead screw 38, the feed pipe 35, and the filter plate 36 to rotate together. A plurality of nozzles 310 are arranged on the feed pipe 35 and at the bottom of the stirring blade 37. The nozzles 310 on the feed pipe 35 are kept flush with the feed pipe 35 to ensure that the filter plate 36 does not interfere with each other when sliding up and down in the stirring bin 312. The flocculant enters the stirring bin 312 through the nozzle 310 and mixes with the wastewater in the stirring bin 312. The stirring of 37 accelerates the fusion of wastewater and flocculant, so that the wastewater can achieve solid-liquid separation as soon as possible. After the solid-liquid separation, the raw material bin 33 stops rotating, and the output end of the motor II 34 rotates the screw 38 to provide power for the filter plate 36, so that the filter plate 36 is guided by the feed pipe 35 and slides from top to bottom in the mixing bin 312. The filter plate 36 is provided with a number of fine holes, which can filter and separate the wastewater from the sediment, and filter the floating sediment in the wastewater to the bottom of the mixing bin 312, so that the wastewater does not need to enter the sedimentation tank for sedimentation, which shortens the sedimentation time.

After the separated wastewater enters the adsorption device 4, the control valve on the slag discharge port II 39 at the bottom of the stirring device 3 is opened to discharge the separated sediment; after the wastewater enters the adsorption device 4, the residual impurities in the wastewater are finally filtered through the activated carbon between the filter mesh I 41 and the filter mesh II 42.
