[0020] See also Figure 1-Figure 8The top part of the locking bolt 10 is movably inserted into the inner side of the insertion hole 31, and the fastening pressure plate 23 is movably inserted into the inner side of the pressure plate insertion hole 32. The fixing bracket 26 is fixedly installed on the sewage treatment tank 4 through the locking bolt 10. The locking bolt 10 and the fastening pressure plate 23 pass through the insertion hole 31 and the pressure plate insertion hole 32 respectively, and then the locking bolt 10 is screwed close to the sewage treatment tank 4 by external force. The rotation of the locking bolt 10 drives the fastening pressure plate 23 to rotate until the bottom end of the fastening pressure plate 23 is close to the top of the fixing bracket 26. At this time, the fixing bracket 26 is fixed to the top of the sewage treatment tank 4 by the locking bolt 10, and the ceramic membrane 24 is located at the inner bottom end of the sewage treatment tank 4. The connecting pipe 25 at one end of the ceramic membrane 24 is fixedly installed at the end of the first branch pipe 14 away from the first delivery pipe 13. The sewage inside the sewage treatment tank 4 intercepts impurities on the outside of the ceramic membrane 24 through the ceramic membrane 24, and the clean water filtered by the ceramic membrane 24 enters The water flows into the water delivery hole 33 and is transported to the inside of the first branch pipe 14 through the connecting pipe 25. The connecting pipe 25 at the other end of the ceramic membrane 24 is fixedly installed at the end of the second branch pipe 20 away from the second main valve 19. The second water pump 17 transports the clean water in the backwash pool 6 to the second branch pipe 20 through the second delivery pipe 18. The second branch pipe 20 transports the clean water to the inside of the water delivery hole 33 through the connecting pipe 25. The clean water flows outward from the inside of the ceramic membrane 24 to wash away the dirt attached to the surface of the ceramic membrane 24, thereby realizing backwashing. The water delivery pipe 36 is fixedly installed on the top of the mounting plate 9, and the hollow floating tube 40 and the hollow floating ball 41 are both located inside the sewage treatment pool 4. The sewage inside the sewage treatment pool 4 applies buoyancy to the hollow floating tube 40 and the hollow floating ball 41. The lifting and lowering of the hollow floating tube 40 and the hollow floating ball 41 drive the lifting and lowering of the gate plate 42, thereby realizing the interception and discharge of the sewage inside the water delivery pipe 36.

[0021] Working principle: During use, the sewage to be treated is first poured into the sewage buffer tank 34 through the filter screen 35, and the filter screen 35 is used to complete the coarse filtration to intercept the larger particles of impurities, and then the valve 37 is opened. At this time, there is no water inside the sewage treatment tank 4, and the hollow float tube 40 and the hollow float ball 41 fall downward without the support of water until the bottom end of the plug 44 is close to the top of the auxiliary support ear 38. At this time, the sewage flows into the sewage treatment tank 4 through the water pipe 36. When the water surface of the sewage contacts the bottom ends of the hollow float ball 41 and the hollow float tube 40, the sewage pushes the hollow float tube 40 and the hollow float ball 41 upward under the action of buoyancy, and the movement of the hollow float tube 40 pushes the gate plate 42 to move upward. When the top end of the gate plate 42 is plugged into the inner side of the top end of the water pipe 36, the sewage inside the water pipe 36 is cut off, and then the filtration is started; Before starting the filtration, first open the first main valve 16 and all the first branch valves 15, close the second main valve 19 and all the second branch valves 21, and connect the end of the drain pipe 11 away from the clean water tank 5 to the clean water storage area, then start the first water pump 12, the sewage inside the sewage treatment tank 4 passes through the ceramic membrane 24 to intercept impurities on the outside of the ceramic membrane 24, the clean water filtered by the ceramic membrane 24 enters the water delivery hole 33 and is transported to the inside of the first branch pipe 14 through the connecting pipe 25, and then transported to the first delivery pipe 13 through the first branch pipe 14, the first water pump 12 transports the clean water inside the first delivery pipe 13 to the inside of the clean water tank 5, When the water inside the clean water tank 5 reaches the connecting pipe 7, the clean water inside the clean water tank 5 flows into the backwashing tank 6 through the connecting pipe 7. When the clean water in the backwashing tank 6 is equal to the clean water in the clean water tank 5, the water level rises to the drain pipe 11, and the clean water is transported to the clean water storage area through the drain pipe 11. When the sewage in the sewage treatment tank 4 is filtered and transported to the clean water tank 5, the water level inside the sewage treatment tank 4 drops, so that the supporting force of the hollow floating tube 40 and the hollow floating ball 41 is weakened and moves downward, thereby driving the gate plate 42 to move downward. When the top of the gate plate 42 is lower than the inner top of the water delivery pipe 36, the sewage flows into the sewage treatment tank 4 for replenishment; When the sewage filtration efficiency is reduced, backwashing is started, and the valve 37 is closed at this time. When the sewage inside the sewage treatment tank 4 is treated to the water surface at the top of the ceramic membrane 24, the valve on the sewage pipe 8 is opened, and then the first water pump 12 and the first main valve 16 are closed, the second main valve 19 and all the second branch valves 21 are opened, and the second water pump 17 is opened. The second water pump 17 transports the clean water inside the backwashing pool 6 to the second branch pipe 20 through the second delivery pipe 18, and the second branch pipe 20 transports the clean water to the inside of the water delivery hole 33 through the connecting pipe 25. The clean water flows outward from the inside of the ceramic membrane 24 to wash away the dirt attached to the surface of the ceramic membrane 24. The remaining sewage inside the sewage treatment tank 4 and the dirt fallen off the surface of the ceramic membrane 24 are discharged through the sewage pipe 8. When the backwashing is completed, the second water pump 17, the second main valve 19 and all the second branch valves 21 are closed, and then the valve 37 is opened to inject sewage into the sewage treatment tank 4 to continue filtering. When a ceramic membrane 24 is damaged, and it is observed through the connecting pipe 25 that the filtered water has a high turbidity or is blocked and cannot be filtered, the first branch valve 15 and the second branch valve 21 at both ends of the ceramic membrane 24 are closed, and the two connecting pipes 25 at both ends of the ceramic membrane 24 are removed from the first branch pipe 14 and the second branch pipe 20 respectively, and then the locking bolt 10 is twisted away from the sewage treatment tank 4 by external force, and the rotation of the locking bolt 10 drives the fastening pressure plate 23 to rotate. When the fastening pressure plate 23 rotates to the top of the pressure plate socket 32, the fixing bracket 26 is pulled upward by external force, and the movement of the fixing bracket 26 drives the ceramic membrane 24 to move upward. After the ceramic membrane filtration device 3 is taken out, the lower arc plate 30 and The caps 29 at both ends of the ceramic membrane 24 are then replaced with a new ceramic membrane 24 for installation. After the installation is completed, the ceramic membrane filtration device 3 is put back in place, and the fixing bracket 26 is pulled by external force to place the ceramic membrane 24 inside the sewage treatment tank 4. The locking bolt 10 and the fastening pressure plate 23 are respectively passed through the plug hole 31 and the pressure plate plug hole 32, and then the locking bolt 10 is screwed close to the sewage treatment tank 4 by external force. The rotation of the locking bolt 10 drives the fastening pressure plate 23 to rotate until the bottom end of the fastening pressure plate 23 is close to the top of the fixing bracket 26, and then the two connecting pipes 25 at both ends of the ceramic membrane 24 are respectively installed on the first branch pipe 14 and the second branch pipe 20, and the first branch valve 15 is opened to complete the replacement.
