[0025] A filter plate 3 and a filter assembly 27 are arranged in sequence from the water inlet pipe 22 to the water outlet pipe 23. The inner bottom surface of the box 1 is provided with a plug-in track 4, and the top of the box 1 is provided with a socket which is arranged vertically opposite to the plug-in track 4. The filter plate 3 is inserted from the socket so that the bottom of the filter plate 3 is placed on the plug-in track 4. Thus, the filter plate 3 can be conveniently replaced.

A brush plate 6 is mounted on the electric telescopic rod 5, and the brush plate 6 is in contact with the two filter surfaces of the filter plate 3. The brush plate 6 is driven by the electric telescopic rod 5 to move up and down so as to clean the filter holes on the filter plate 3.

[0026] A baffle 21 is arranged between the water inlet pipe 22 and the filter plate 3, and the width of the baffle 21 is equal to the inner width of the box 1. A first water quality detection probe 25 is arranged at the upper end of the baffle 21, and the first water quality detection probe 25 is arranged towards the water inlet pipe 22. A second water quality detection probe 26 is arranged on the inner wall surface of the box 1 where the water outlet pipe 23 is arranged.

The acid-base neutralizer medicine bin 7 and the oxidizing agent medicine bin 9 are respectively provided with a medicine feeding pipe 10. A control valve 8 is arranged on each medicine feeding pipe 10. A large amount of oxidizing agent and acid-base neutralizer is respectively arranged in the medicine bin 29.

[0028] The control center 11 and the driving mechanism 28 are mounted on the top of the box 1 in a sealed manner to prevent water and dust. The filter assembly 27 includes a driving mechanism 28 mounted on the box 1, a stirring shaft 17 connected to the power output end of the driving mechanism 28, and a purple light lamp 19 arranged correspondingly to the stirring shaft 17. The stirring shaft 17 and the purple light lamp 19 are located in the box 1. A plurality of stirring rods 18 are vertically connected to the stirring shaft 17 and are uniformly distributed in the axial direction of the stirring shaft 17. The plurality of stirring rods 18 can be located in the same vertical plane or staggered. The purple light lamp 19 is wrapped with a quartz cover 20 so as to isolate the purple light lamp 19 from the sewage, and the ultraviolet lamp tube can penetrate the quartz cover 20.

[0029] The driving mechanism 28 comprises the motor 12 and the planetary gear 13, the number of the stirring shafts 17 and the ultraviolet lamps 19 is multiple, one stirring shaft 17 and one ultraviolet lamp 19 are correspondingly connected on each pinion of the planetary gear 13, and the motor shaft of the motor 12 is connected with the sun gear of the planetary gear 13. In the embodiment, the number of the pinions is four, and four groups of the stirring shafts 17 and the ultraviolet lamps 19 are correspondingly arranged.

[0030] The control center 11 is electrically connected with the first water quality detection probe 25, the electric telescopic rod 5, the control valve 8, the ultraviolet lamp 19, the driving mechanism 28 and the second water quality detection probe 26 respectively. The first water quality detection probe 25 is used for detecting the pH value and the COD of the inlet water, the second water quality detection probe 26 is used for detecting the pH value and the COD of the outlet water, the detected data is fed back to the control center 11, the control center 11 compares the received data with the set data, if the comparison result is unqualified, the control valve 8 is started to open the acid-base neutralizer cartridge 7 and / or the oxidant cartridge 9 and / or adjust the opening intensity of the ultraviolet lamp 19, until the comparison result is qualified. The ultraviolet intensity and the dosing amount are controlled by the control center 11, which not only makes the degradation of organic matter more efficient, but also saves resources.

[0031] The photovoltaic panel 15 is installed on the upper end of the box body 1 through the support 14, and the storage battery 16 is arranged in the box body 1. The photovoltaic panel 15 and the storage battery 16 can provide power for the whole sewage purification equipment.

[0032] By starting the motor 12, the pinion in the planetary gear 13 is driven to rotate around the sun gear, so as to give the stirring shaft 17 the maximum stirring range. When the cross-shaped stirring shaft 17 formed by the stirring shaft 17 and the stirring rod 18 rotates, the sewage can be fully stirred, at the same time, the sewage is fully acted on by the ultraviolet lamp 19, and the oxidant fully contacts with the sewage, so that the organic matter in the sewage is completely oxidized.

[0033] The ultraviolet lamp distributed outside the stirring shaft 17 can cooperate with the immobilized catalyst to more effectively degrade the organic matter. When the concentration of the organic pollutants is large, the oxidant is activated by the ultraviolet light and the catalyst to produce active substances to rapidly degrade the organic pollutants.

[0034] The filter assembly 27 is an independently installable component, the number of the pinion, the stirring shaft 17 and the ultraviolet lamp 19 can be adjusted according to actual needs, and the filter assembly 27 is convenient to maintain and replace.

[0035] In use, the driving mechanism 28 is started to rotate the stirring shaft 17 and the ultraviolet light 19. The water inlet pipe 22 and the water outlet pipe 23 are connected with the pipeline respectively, and the sewage enters the box 1 from the water inlet pipe 22. First, the large particles in the sewage are blocked by the baffle 21. The filtered large-particle sewage flows to the filter plate 3 from the gap between the baffle 21 and the box 1, and at the same time, small-particle impurities are filtered by the filter plate 3. The filtered large-particle and small-particle impurities are deposited in the box 1. When the deposited sludge reaches a certain degree, the sewage purification device is closed, and the sludge discharge pipe 24 is opened to discharge the deposited sludge. An sewage pump can be connected outside the sludge discharge pipe 24. When the sewage enters from the water inlet pipe 22, the first water quality detection probe 25 is triggered, and the detected value is fed back to the control center 11. The control center 11 controls the control valve 8 and the ultraviolet light 19. Under the action of the stirring shaft 17, the sewage fully contacts with the reagent and the ultraviolet light when passing through the filter assembly 27, so that the oxidation of the organic matter in the sewage is more thorough. The ultraviolet light 19 not only has a sterilization effect, but also activates the oxidant.

[0036] After being used for a period of time, the electric telescopic rod 5 is started to clean the filter plate 3 by the up-down movement of the brush plate 6, so as to prevent the filter plate 3 from being blocked by impurities.

[0037] According to different actual needs of sewage treatment, the number of the stirring shaft 17, the stirring rod 18, the ultraviolet light 19 and the quartz cover 20 can be increased or decreased, and the area of the photovoltaic panel 15 and the capacity of the storage battery 16 can be increased or decreased, so that the sewage is efficiently treated, and resource waste is avoided.

[0038] In addition, a valve can be arranged on the water inlet pipe 22, and the water inlet speed can be controlled by the control center 11 to adjust the residence time of the sewage in the box 1.

[0039] According to needs, a water pump can be connected to the water outlet pipe 23.

[0040] The above only describes the embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
