Further, referring to fig. 3, fig. 4 and fig. 5, the lifting assembly 130 includes: guide rail 131, baffle 132, first half-shell 133a, second half-shell 133b, center post 134, drive 136a, and lifter 136 b.
The guide rail 131 is disposed along the height direction of the processing tank 110, and the uv assembly 120 is slidably coupled to the guide rail 131.
The number of the baffle plates 132 is two, the two baffle plates 132 are arranged in parallel and spaced apart from each other, and the baffle plates 132 are also arranged in the height direction of the treatment tank 110. The two baffles 132 have a gap therebetween for receiving the first half shell 133a, the second half shell 133b, and the center post 134.
The first half shell 133a and the second half shell 133b are both arc-shaped in cross section, and both extend along the length direction of the baffle 132. The inner arc walls of the first half-shell 133a and the second half-shell 133b are arranged oppositely, the outer arc walls of the first half-shell 133a and the second half-shell 133b are both provided with external threads 137, and the external threads 137 of the first half-shell 133a and the second half-shell 133b are matched and located on the same spiral line. Both the first half-shell 133a and the second half-shell 133b are slidable relative to the barrier 132 in the width direction of the treatment tank 110 so that both the first half-shell 133a and the second half-shell 133b can move toward and away from each other. The uv assembly 120 is provided with internal threads for mating with the external threads 137 of both the first half-shell 133a and the second half-shell 133 b.
The center post 134 is disposed between the first half-shell 133a and the second half-shell 133 b. A first connecting piece 135a is connected between the first half-shell 133a and the central column 134, and two ends of the first connecting piece 135a are respectively hinged with the first half-shell 133a and the central column 134. A second connector 135b is connected between the second half-shell 133b and the center post 134, and two ends of the second connector 135b are respectively hinged with the second half-shell 133b and the center post 134. The rotation axes of the hinges of the first and second connectors 135a and 135b are disposed perpendicular to the baffle 132.
The central post 134 penetrates through the top wall of the processing tank 110 and is driven by a driver 136a, and after the driver 136a drives the central post 134 to rotate, the central post 134 can drive the baffle 132, the first half-shell 133a and the second half-shell 133b to rotate together, so that the external threads 137 of the first half-shell 133a and the second half-shell 133b operate, thereby driving the uv assembly 120 to move along the guide rail 131.
The driver 136a is mounted on the lifting portion of the lifter 136b, and the lifter 136b is mounted on the top of the processing tank 110, and is used for lifting or lowering the driver 136a along the axial direction of the central column 134, that is, for controlling the driver 136a to move in the height direction of the processing tank 110. When the driver 136a is lowered to move the center post 134 into the processing tank 110 and the first connector 135a and the second connector 135b are perpendicular to the center post 134, the first half-shell 133a and the second half-shell 133b are smoothly pushed away from each other, at this time, the external threads 137 of the first half-shell 133a and the second half-shell 133b are just matched with the internal threads of the uv light assembly 120, and the driver 136a drives the center post 134, so that the uv light assembly 120 can be driven.
When the lifter 136b lifts the driver 136a, the driver 136a pulls the central post 134 upward, and the central post 134 pulls the first connector 135a and the second connector 135b upward, so that the first half shell 133a and the second half shell 133b are close to each other, and the external threads 137 of the first half shell 133a and the second half shell 133b are separated from the internal threads of the uv assembly 120, even if the central post 134 rotates, the uv assembly 120 cannot be driven.
Through the above design, the ultraviolet light assembly 120 may be driven along the guide rail 131, the ultraviolet light assembly 120 is driven to the bottom end of the guide rail 131, and then the driver 136a is lifted by the lifter 136b, so as to release the transmission fit relationship between the first half shell 133a and the second half shell 133b and the ultraviolet light assembly 120, and at this time, under the buoyancy of the sewage, the ultraviolet light assembly 120 returns to the upper end of the guide rail 131 along the guide rail 131 again. This achieves a reciprocating motion of the uv assembly 120. In the process of floating the uv assembly 120, the driver 136a may be temporarily stopped, and then started when the uv assembly 120 needs to be driven to the bottom end of the guide rail 131 again, which further saves energy.
The ultraviolet light assembly 120 performs reciprocating motion along the height direction of the treatment tank 110 and is also beneficial to improving the treatment effect on sewage, so that the ultraviolet light can irradiate the sewage in the whole treatment tank 110 more fully, and stir the sewage simultaneously, thereby avoiding the problem of insufficient local irradiation.

Thus, when the ultraviolet light assembly 120 is floated by sewage, or the central column 134 is driven by the driver 136a, the ultraviolet light assembly 120 is driven to the top end of the guide rail 131, so that the structural body 122 of the ultraviolet light assembly 120 is in contact with the first base 138, and the ultraviolet light assembly 120 is wirelessly charged for the lamp 123 to use.
Further, the number of the guide rails 131 is two, the two guide rails 131 are both cylindrical, and the first half shell 133a and the second half shell 133b are both located between the two guide rails 131, so as to improve the stability of the ultraviolet light assembly 120 during floating.
Through the improvement, the sewage treatment effect can be effectively improved by utilizing the mode of combining ultraviolet pretreatment and MBR membrane treatment, and the service life of the MBR membrane is prolonged. Under the condition of guaranteeing the sewage treatment effect, the maintenance cost of the equipment is reduced.
It should be noted that the driver 136a may be a motor equipped with a speed reduction mechanism, and the lifter 136b may be a cylinder assembly, without being limited thereto.
In conclusion, the novel MBR membrane sewage treatment system 1000 has higher sewage treatment capacity and better sewage treatment effect, the cleaning and maintenance frequency and cost of equipment are well controlled, and the use cost is reduced while the sewage treatment effect is ensured.
