As shown in FIG. 8, the efficient antimony removal process for printing and dyeing wastewater, which adopts the treatment equipment, comprises the following process steps:

s1: firstly, respectively installing adsorbents 5 on filter plates 4 at different positions in a box body 1, and uniformly distributing the adsorbents at each part on the filter plates 4;

s2: then, pretreating the printing and dyeing wastewater to be treated by a three-stage sedimentation tank in advance, and pumping the treated wastewater into the box body 1 from the water inlet pipe 2 through a water pump;

s3: after the wastewater in the box body 1 flows from top to bottom, antimony in the wastewater is removed through the adsorbent 5 on the filter plate 4, and then the treated wastewater is discharged through the water outlet pipe 3 at the bottom end of the box body 1; when rivers are in box 1 inside from top to bottom flow, rivers can be more abundant with the adsorbent 5 contact reaction of higher frequency and different positions to improve the antimony removal efficiency of waste water, filter 4 can intercept the impurity in the waste water simultaneously, thereby further improved the treatment effect of waste water behind box 1.

The working principle is as follows: when the treatment equipment is used, the adsorbent 5 (such as iron sulfide) can be respectively arranged on the filter plates 4 at different positions in the box body 1 and uniformly distributed at each position on the filter plates 4, when water flows from top to bottom in the box body 1, the water flow can fully contact and react with the adsorbent 5 at different positions with higher frequency, so that the multi-stage antimony removal can be carried out on the wastewater, the antimony removal efficiency of the wastewater is improved, and meanwhile, the filter plates 4 can intercept impurities in the wastewater, so that the treatment effect of the wastewater after passing through the box body 1 is further improved; when the wastewater is subjected to antimony removal treatment, the motor 8 drives the inner net sleeve 6 and the outer net sleeve 7 to rotate, so that the adsorbent 5 in the inner cavity rotates and rolls in the wastewater, the contact reaction effect of the adsorbent 5 and the wastewater is further improved, and meanwhile, when the outer net sleeve 7 rotates, the outer net sleeve 7 can also rotate intercepted impurities to the side wall of the box body 1 and intensively collect the impurities at the included angle between the box body 1 and the side wall of the outer sheath under the limiting obstruction of the inner wall of the box body 1, so that the self-cleaning effect on the filter plate 4 is achieved, and the blocking condition of the filter plate 4 is reduced; when the adsorbent 5 between the arc-shaped net 10 and the inner net sleeve 6 needs to be replaced due to long-time work, the arc-shaped net 10 is only required to be rotated to the position right opposite to the material changing groove 11, the material changing groove 11 is opened by rotating the baffle plate 12, the adsorbent 5 in the arc-shaped net 10 flows out under the action of the arc-shaped surface of the guide block 13 by detaching the end part of the arc-shaped net 10, meanwhile, the unused adsorbent 5 is added between the arc-shaped net 10 and the inner net sleeve 6 again, and the adsorbent 5 is limited after the arc-shaped plate is rotated and installed, so that the adsorbent 5 in the box body 1 can be conveniently and quickly replaced; by arranging the position of the rotating connecting end of the arc-shaped net 10, when the arc-shaped net 10 moves to the material changing groove 11, the rotating point of the arc-shaped net is located at the position of the bottom baffle 12 of the two baffles 12, at the moment, the arc-shaped net 10 is opened, new adsorbent 5 is placed at the arc-shaped net 10, at the moment, when the arc-shaped net 10 is loosened, the arc-shaped net 10 can automatically rotate and reset under the action of the torsion spring, and the adsorbent 5 is automatically conveyed to a cavity between the arc-shaped net 10 and the inner net sleeve 6, so that the replacement work of the adsorbent 5 is more convenient; when more impurities in the included angle between the inner wall of the box body 1 and the arc-shaped sleeve need to be cleaned, the impurities in the included angle can be conveniently recovered only by opening the opening-closing door 15 at the discharge groove 14; when the discharge groove 14 is opened and impurities are recovered, in order to reduce the environmental pollution caused by the outflow of wastewater in the box body 1, the wastewater in the box body 1 needs to be discharged in advance, at this time, a blocking structure is arranged at the discharge groove 14, when the impurities are required to be recovered, the push rod 16 drives the blocking plate 17 and the sliding sleeve 18 to move downwards until the sliding plate 19 moves to the arc-shaped net 10 and the conical body is inserted into the net mouth of the arc-shaped net 10, then the arc-shaped net 10 is driven by the motor 8 to rotate anticlockwise, so that the arc-shaped net 10 can drive the sliding plate 19 to move synchronously by the matched conical body until the sliding plate 19 moves to the position attached to the inner wall of the box body 1, and at this time, the sliding plate 19, the blocking plate 17 and the inner wall of the box body 1 can form a closed chamber, so that when the impurities in the chamber are cleaned and discharged, the wastewater in the box body 1 cannot flow out at the same time, the impurities do not need to be emptied when the impurities are recovered, and the convenience of the box body 1 is further improved; the sliding plate 19 (which can be made of a deformable metal strip) can move to the concave part 22 under the matching of the arc-shaped net 10 and the conical body, and at the moment, the water pressure in the box body 1 can apply certain pressure to the sliding plate 19, so that the end part of the sliding plate 19 can strongly press the side wall of the concave part 22, and the condition that the wastewater in the box body 1 leaks from the position between the sliding plate 19 and the box body 1 when impurities are discharged is reduced; the conical block 21 can only rotate anticlockwise but cannot rotate clockwise by arranging the limiting strip 24 at the conical block 21, so that the conical block 21 can move under the driving of a net opening after being inserted into the net opening of the arc-shaped net 10, when the sliding plate 19 moves to a position close to the magnetic block 23, the magnetic block 23 can attract the sliding plate 19, the sliding plate 19 can be matched with the concave part 22 more quickly and efficiently, and meanwhile, the conical block 21 can swing anticlockwise under the action of the net opening of the arc-shaped net 10, so that the sliding plate can slide relative to the arc-shaped net 10, and the movement of the sliding plate 19 can be smoothly carried out; when the sliding plate 19 slides in the sliding sleeve 18 under the adsorption of the magnetic block 23, along with the increase of the space in the sliding sleeve 18, the sliding sleeve 18 can exhaust air to the sliding groove through the air pipe 28, so that the ejector pins 26 retract under the action of the air pressure in the sliding groove, and the ejector pins 26 are pulled out from the net opening of the arc-shaped net 10, thereby reducing the resistance when the sliding plate 19 and the arc-shaped net 10 move relatively.
