The power transmission mechanism 3 comprises an annular fan or an air pump and a hydraulic station, wherein the annular fan provides a compressed air source for the aeration mechanism 16, the back flushing mechanism 14 and the slag removal air pipe. The hydraulic station provides hydraulic power for the lifting cylinder 19 and the water control hydraulic cylinder 31, so that the equipment can work stably and normally. The device can also replace a hydraulic station by using a pneumatic control system, and the air compressor is used for generating compressed air to push the air cylinder, so that water pollution caused by accidental leakage of hydraulic oil is avoided.
As shown in fig. 2, a drainage channel 5 is formed on the central axis of the water body purifying units 4, and an axial flow impeller 6 is arranged in the drainage channel 5; the end part of the drainage channel 5 is communicated with a drainage pipe 7, and a water control gate valve 8 is arranged in the drainage pipe 7. The axial flow impeller 6 mainly provides power for the circulating flow of the water body in the tank body 1, and under the pushing action of the axial flow impeller 6, the sewage to be treated in the environment can be sucked with extremely low energy consumption, so that the energy consumption is effectively reduced. The drainage channel 5 is a channel for water to flow out after purification, the drainage channel 5 is used as a main drainage pipe, the bottom end of the main drainage pipe is connected with a plurality of corresponding branch drainage pipes, and the four drainage pipes are respectively positioned in the east-west direction, so that the direction can be conveniently controlled.

As shown in fig. 2, the water purifying unit 4 comprises a water inlet cavity 10 communicated with an external water body and provided with a water inlet 9, a filling cavity 11 positioned above the water inlet cavity 10 and communicated with the water inlet cavity 10, and a clear water cavity 12 positioned above the filling cavity 11 and communicated with the filling cavity 11, wherein the clear water cavity 12 is communicated with the drainage channel 5; a slag removing mechanism 13 is arranged at the water inlet 9 of the water inlet cavity 10, and a back flushing mechanism 14 is arranged in the water inlet cavity 10; the filler cavity 11 is internally piled with a fixed biological film filler 15 and an aeration mechanism 16 corresponding to the back flushing mechanism 14, and the aeration mechanism 16 and the back flushing mechanism 14 are respectively connected with the power transmission mechanism 3.
The power transmission mechanism 3 is an annular fan or an air pump; the fixed type biological membrane 15 has high porosity, large specific surface area, high mechanical strength and high biological load. When the equipment works, the axial flow impeller 6 runs, sewage enters the water inlet cavity 10 through the slag removing mechanism 13, and larger impurities in the sewage are removed through the slag removing mechanism 13; after the sewage enters the water inlet cavity 10, the sewage continuously rises to enter the filling cavity 11, the aeration mechanism 16 in the filling cavity 11 aerates the water to enrich the water body with dissolved oxygen, so that aerobic bacteria on the filling material are greatly propagated, finally, a biological film taking the aerobic bacteria as a main body is formed, after the sewage containing organic pollutants contacts with the biological film, the organic pollutants are converted into harmless simple molecules through metabolism by the aerobic bacteria, and the organic matters are metabolized and purified by microorganisms, so that the sewage is purified. The evolved water body flows into the water discharge channel 5 through the clean water cavity 12, and is pushed to the water discharge pipe 7 through the axial flow impeller 6 so as to be discharged outwards. When the equipment works for a period of time, the biomembrane on the fixed biomembrane filling 15 has aging tendency or has a certain degree of blockage, the resistance of the fixed biomembrane filling 15 can be increased, at the moment, the fixed biomembrane filling 15 is backwashed through the backwashing mechanism 14, the annular fan supplies air to the backwashing mechanism 14, and the air-containing water with extremely high strength forcedly backflushes the biomembrane on the fixed biomembrane filling 15 upwards, so that the biomembrane is updated, and the sewage purification effect is improved.
After the equipment works for a period of time, slag may be blocked on the slag removing mechanism 13, in order to facilitate the slag removal on the slag removing mechanism 13, as shown in fig. 3, in the invention, the slag removing mechanism 13 comprises a grid 17 arranged at the water inlet 9, a slag remover 18 in matched connection with the grid 17, and a lifting cylinder 19 connected to the slag remover 18, wherein the lifting cylinder 19 is arranged along the axial direction of the tank body 1. The lifting cylinder 19 adopts a hydraulic cylinder and comprises a cylinder barrel and a piston rod, wherein the cylinder barrel is arranged at the upper end of the tank body 1, and the tail end of the piston rod is connected with the slag remover 18. The slag remover 18 can move up and down in the grille 17 under the driving action of the lifting cylinder 19, and can push slag blocked at the grille 17 outwards to remove the slag.
In order to improve the operability of the slag removing mechanism 13, as shown in fig. 4 to 5, in the present invention, the grid 17 includes a slag plate 20 having a cavity therein and being connected to the water inlet 9 of the tank 1 by bolts, and a grid gap 21 uniformly provided on the slag plate 20, and the slag remover 18 includes a fixing rod 22 axially penetrating the slag plate 20 and being connected to the lifting cylinder 19, a fixing plate 23 connected to the bottom end of the fixing rod 22, and slag removing protrusions 24 provided on the fixing plate 23, and the slag removing protrusions 24 correspond to the grid gap 21. The water enters the water inlet cavity 10 through the grid gap 21, and the larger impurities in the sewage are blocked through the filtering action of the grid gap 21, so that the sewage purifying effect is prevented from being influenced by the larger impurities entering the tank body 1. The fixed rod 22 in the slag remover 18 is connected with the piston rod in the lifting cylinder 19, and the telescopic action of the piston rod drives the lifting of the fixed rod 22, so that the slag removing convex block 24 moves up and down in the grid gap 21 to push slag in the grid gap 21 outwards, thereby improving the slag removing effect and the operability of slag removal.
In order to avoid the influence of displacement deviation of the slag remover 18 in the up-and-down movement process on the slag removing effect, in the invention, the two ends of the inside of the slag separation plate 20 are provided with guide slide bars 25, and the two ends of the fixed plate 23 of the slag remover 18 are provided with sleeves 26 which are matched and connected with the guide slide bars 25. The guide slide bar 25 is vertically arranged and plays a role in guiding and positioning in the matched connection of the slag remover 18 and the grille 7. The sleeve 26 is sleeved on the guide slide bar 25, the lifting cylinder 19 drives the slag remover 18 to move up and down along the guide slide bar 25 in the grid 17, and the movement is stable and reliable, so that the position deviation in the moving process is effectively avoided.
In order to enhance the backwashing effect on the fixed type biofilm packing 15 and the outward discharging effect on the slag at the slag removing mechanism 13, as shown in fig. 6, a valve 27 is hinged to the upper wall of the water inlet 9 of the tank 1, and the valve 27 is hinged to the end of the fixed rod 22 in the slag remover 18 through a connecting rod 28. The lifting cylinder 19 is a driving part, and the control of the movable opening and closing state is driven by the connecting rod 28 under the driving action of the lifting cylinder 19. In normal water intake, the piston rod of the lifting cylinder 19 is lifted upward, and the shutter 27 is opened. When back flushing operation is carried out, a piston rod in the lifting cylinder 19 descends to drive the fixing rod 22 to descend, so that the valve 27 is closed to block the water inlet 9, and air flow released by the back flushing mechanism 14 cannot leak outwards through the grid 17 and intensively rushes to the filling area. And the backwashing effect is improved. When the slag removing mechanism 13 performs slag removing operation, the lifting cylinder 19 drives the fixing rod 22 to move downwards, so that the slag remover 18 is at the lowest position, the valve 27 is closed at the moment, the water inlet 9 is blocked, the air flow is intensively flushed towards the grid gap 21, and the air flow is prevented from escaping from the valve to the inside of the water inlet cavity.
In order to facilitate the slag removal mechanism 13 to remove the removed slag and discharge the slag out of the tank 1, as shown in fig. 6, in the invention, a slag discharge air pipe 29 connected with the power transmission mechanism 3 is also communicated with the water inlet 9, and the slag discharge air pipe 29 corresponds to the grid 17. While the slag remover 18 moves up and down, the slag removing air pipe blows air into the gaps of the grille 17, which is helpful for removing slag outwards and discharging the slag out of the tank 1.
