Secondly, by arranging the impeller 7 in the water inlet area 1-2, sediment and silt remained in the sewage can be deposited and accumulated in the water inlet area 1-2 within the area between the two blades 7-2 at the top of the impeller shaft 7-1 after the sewage enters the water inlet area 1-2 from the water inlet; after the impeller 7 rotates clockwise, sediment and sludge accumulated on the impeller 7 can enter the accommodating cavity 1-3 and are separated below the water inlet area 1-2 by the impeller 7, and finally fall into the water inlet sewage discharging channel 1-4, so that the sediment and sludge cleaning effect of the water inlet area 1-2 is sequentially achieved, and the sewage treatment efficiency of the equipment is improved.
Specifically, the filter layer 2, the first permeation reaction layer 3 and the second permeation reaction layer 4 are distributed at intervals, and the water treatment sewage channels 1-5 are arranged at the positions of the bottoms of the water treatment channels 1-1 corresponding to the intervals.

Wherein valves are arranged on the water inlet blow-down channel 1-4 and the water treatment blow-down channel 1-5, and the valves are used for controlling the opening/closing of the water inlet blow-down channel 1-4 and the water treatment blow-down channel 1-5.
Further, the surface of the filter layer 2 is provided with the blades 2-1 at equal intervals, the blades 2-1 are provided in four in the same number as the blades 7-2, and the four blades 2-1 are provided in a one-to-one correspondence with the four blades 7-2. The impeller shaft 7-1 is arranged in a direction parallel to the width of the main body 1, in which case two blades 7-2 are located at the top of the impeller shaft 7-1 and the other two blades 7-2 are located at the bottom of the impeller shaft 7-1. Four blades 2-1 are provided one on each side, top and bottom of the barrel structure 5. Of the two blades 7-2 located at the top of the impeller shaft 7-1, the outer ends of the downstream blades 7-2 are in contact with the plane of the upstream side of the lowermost blade 2-1, and the blades 2-1 located at the upper and lower sides of the filter layer 2 are in contact with the inner wall surfaces of the upper and lower sides of the water treatment channel 1-1.
Specifically, the contact of the blades 7-2 with the blades 2-1 blocks water, and the contact of the upper and lower blades 2-1 with the inner wall surface of the water treatment channel 1-1 blocks water, so that the sewage in the water inlet area 1-2 is restricted to permeate the filter layer 2.
Furthermore, the upper and lower sides of the water treatment channel 1-1 are provided with arc grooves 1-6 adapted to the arc track of the outer side of the blade 2-1. The downstream end of the circular arc groove 1-6 extends into the water treatment channel 1-1 along the circular arc track of the blade plate 2-1, and the blade plate 2-1 laterally downstream of the circumferential direction of the cylindrical structure 5 enters the circular arc groove 1-6 before the uppermost blade plate 2-1 leaves the circular arc groove 1-6 above from the upstream end of the circular arc groove 1-6 when the cylindrical structure 5 rotates counterclockwise. So as to achieve the purpose that the blades 2-1 are matched with the arc-shaped grooves to prevent sewage from avoiding the filter layer 2 and directly entering the first permeation reaction layer 3.
Further, the lowermost louver 2-1 of the filter layer 2 is located upstream of the issued circular arc groove 1-6, the lowermost louver 2-1 extends from the bottom end to downstream with the first circular arc portion 2-2 extending into the circular arc groove 1-6, and the upstream end of the lower circular arc groove 1-6 is located at the intersection point of the lower of the two intersection points of the circular arc track where the accommodating cavity 1-3 is located and the circular arc track where the outer end of the louver 2-1 is located, and the downstream end of the top opening of the accommodating cavity 1-3 coincides with the intersection point.
Specifically, the filter layer 2 and the impeller 7 have the process of synchronously performing reverse rotation under the state that the blades 7-2 are kept in contact with the impeller 2-1, and the critical position of separation of the blades 7-2 and the impeller 2-1 is the intersection point, so that the blades 7-2 are kept in contact with the impeller 2-1 all the time in the rotation process of the impeller 7 and the filter layer 2, and the impeller 2-1 is contacted with the arc grooves 1-6 below when the blades 7-2 are separated from the impeller 2-1, thereby ensuring that the effect of preventing sewage from avoiding the filter layer 2 and directly entering the first permeation reaction layer 3 is achieved in the whole process.
Further, the vane 7-2 has a second circular arc portion 7-3 of circular arc shape extending upstream from the outer end thereof, and the outer end of the second circular arc portion 7-3 is in surface contact with the filter layer 2 while the filter layer 2 rotates clockwise so that the lowermost vane plate 2-1 enters the circular arc-shaped groove. At this time, the second arc part 7-3 is matched with the filter layer 2, so that sediment and silt can be prevented from entering the arc grooves 1-6 below, and meanwhile, sewage can be prevented from directly crossing the filter layer 2.
Referring to fig. 3 to 8, in particular, the apparatus rotates the filter layer 2 and the impeller 7 clockwise in synchronization with each other during operation, so that the blades 7-2 and the vane plates 2-1 are switched to separated critical point positions. Then, the impeller 7 is made to be stationary and keeps the filter layer 2 to continue to rotate anticlockwise, when the next blade plate 2-1 rotates to the position between two intersection points of the arc where the outer surface of the first arc part 2-2 is located and the arc where the second arc part 7-3 is located, the first arc part 2-2 on the original blade plate 2-1 is still located in the issued arc groove 1-6, and at the moment, the filter layer 2 stops rotating. After that, the impeller 7 rotates until the second circular arc portion 7-3 on the upstream one of the blades 7-2 contacts the above-mentioned blade plate 2-1 corresponding to the one end of the blade 7-2. Finally, the filter layer 2 and the impeller 7 synchronously rotate reversely until the next blade plate 2-1 moves to the position where the original blade plate 2-1 is located, and in the process, the cooperation of the blade 7-2 and the blade plate 2-1 always keeps the blocking of sewage, so that the sewage is prevented from avoiding the filter layer 2 and directly entering the first permeation reaction layer 3. In this way, a single rotation of the filter layer 2 and the impeller 7 is achieved. And in the process both the filter layer 2 and the impeller 7 are rotated 90 deg..
In the above process, the next blade 2-1 rotates to a position between two intersecting points of the arc where the outer surface of the first arc portion 2-2 is located and the arc where the second arc portion 7-3 is located, until the second arc portion 7-3 on the upstream blade 7-2 corresponds to a process that one end of the blade 7-2 contacts with the blade 2-1, and in a process that sewage in the water inlet area 1-2 enters the circular arc groove 1-6 below, sediment and sludge carried in by the next blade 2-1 are discharged into the first water treatment sewage discharge 1-5 channel in the water treatment channel 1-1, so as to ensure that sediment and sludge cannot enter the first permeable reactive barrier 3.
Further, the upstream inner wall surface of the main body 1 is provided with a matching inclined surface 1-7 extending upwards from the upstream end of the accommodating cavity 1-3 along the plane parallel to the blade 7-2 above the impeller shaft 7-1 and positioned at the upstream, the inclined surface is provided with a sealing plate 8 with the top end connected with the main body 1 in a part of rotation in parallel, and the bottom end extends to the blade 7-2. During rotation of the impeller 7, the sealing plate 8 is pushed and swung once by the blades 7-2. The sealing plate 8 is used for preventing sediment and sludge from entering between the blades 7-2 and the inner wall of the upstream end of the solute cavity in the process of entering the water inlet zone 1-2 from the water inlet.
Specifically, the main body 1 is provided with a collecting cavity 1-8 positioned below the water treatment channel 1-1 and the accommodating cavity 1-3, and the accommodating cavity 1-3 and the water treatment channel 1-1 are communicated with the collecting cavity 1-8 through the water inlet and drainage channel 1-4 and the water treatment drainage channel 1-5 respectively. The collecting cavity 1-8 is used for receiving sediment and sludge discharged from the water inlet sewage disposal channel 1-4 and the water treatment sewage disposal channel 1-5 so as to facilitate centralized treatment of the sediment and sludge.
In conclusion, the non-ferrous metal mine acid wastewater in-situ cooperative treatment equipment has the functions of discharging sediment and silt and loosening fillers, so that the sewage treatment efficiency is guaranteed.
