DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer to Figures 1-7 The utility model provides the following technical scheme: multi-zone collaborative type grid ecological sewage purification equipment, including purification tank 1 and the sewage inlet 7 and sewage outlet 8 connected at the both ends of purification tank 1, the inside installation of purification tank 1 has partition 2, purification tank 1 is divided into anaerobic zone 3, anoxic zone 4 and aerobic zone 5 by partition 2, the right side of purification tank 1 located in aerobic zone 5 is connected with clean water zone 6, the surface of partition 2 is through and is provided with flow guide groove 9, the inside of anaerobic zone 3, anoxic zone 4 and aerobic zone 5 is filled with filter material 10, the top of purification tank 1 is connected with sealing cover 11, and sealing cover 11 is connected with observation window 12 on the surface.

[0028] ​In the preferred embodiment, the anaerobic zone 3 is divided into six areas by the partition 2, the anoxic zone 4 and the aerobic zone 5 are each divided into three areas by the partition 2, and the flow guide groove 9 is arranged in a high-low distribution manner.

[0029] In the preferred embodiment, the anaerobic zone 3, the anoxic zone 4 and the aerobic zone 5 are connected by the flow guide groove 9, and the clear water zone 6 is connected to the aerobic zone 5 by the flow guide groove 9.

[0030] In the preferred embodiment, the filter material 10 is a straight plate honeycomb mesh filler.

[0031] In the preferred embodiment, when the ecological wastewater purification equipment is in use, wastewater first enters from the wastewater inlet 7 and then flows to the anaerobic zone 3. In the anaerobic zone 3, the wastewater fills the six areas in turn along the high distribution flow guide groove 9. Specifically, after the anaerobic zone 1 is filled with wastewater, the wastewater flows to the anaerobic zone 2 along the flow guide groove 9 at the high position of the partition 2; after the anaerobic zone 2 is filled with wastewater, the wastewater flows to the anaerobic zone 3 along the flow guide groove 9 at the low position of the partition 2; and so on, until the wastewater flows from the anaerobic zone 6 to the anoxic zone 4. Then, the wastewater flows from the three areas of the anoxic zone 4 to the three areas of the aerobic zone 5, and continues to flow along the three areas of the aerobic zone 5, and finally reaches the clear water zone 6 for storage. Or, the wastewater is discharged from the wastewater outlet 8 on one side of the clear water zone 6.

[0032] In this process, the wastewater enters and fills each of the twelve grid areas of the anaerobic zone 1 to the anaerobic zone 6, the anoxic zone 4 and the aerobic zone 5 in turn, forming a multi-zone collaborative operation. At the same time, the design of the twelve grid areas increases the specific surface area of the box, ensuring uniform water flow. The water inlet and outlet of each grid are provided with a flow guide groove 9, which not only increases the solid surface area on which active bacteria can survive, but also effectively prevents the occurrence of short circuit phenomenon.

[0033] In addition, increasing the solid surface area on which active bacteria can survive can also avoid the formation of active sludge after the death of active bacteria, thereby preventing problems such as sludge sedimentation and sludge bulking, and ensuring that the suspended solids in the effluent do not exceed the standard and the water quality is clear. In the whole process, water relies on natural flow of liquid level, without the need for additional power. When the clear water does not have the condition of external discharge, the clear water zone 6 can also be used for storage.

[0034] In summary, the multi-zone collaborative grid ecological wastewater purification equipment avoids the problem that the water quality of the effluent is affected by insufficient treatment time.

[0035] It is worth noting that the connection of the observation window 12 on the sealing cover 11 allows for convenient observation of water quality at any time. The filter material 10 is a straight plate honeycomb mesh filler, which can be supported in the grid for a long time without collapse, increasing the loading bacteria specific surface area. At the same time, it also solves the problem that the filter material 10 is damaged and deposited at the bottom of the box after a long time, causing blockage and being difficult to clean, and the treatment effect is reduced due to the lack of contact with wastewater.

[0036] Example Two

[0037] Please refer to Figures 1-7 The four-corner outer wall of the sealing cover 11 is provided with a fixing block 13, the bottom end of the fixing block 13 is connected with a rotating rod 14, the surface of the rotating rod 14 is sleeved with a spring 15, one end of the spring 15 is connected with the bottom end of the fixing block 13, and the end of the rotating rod 14 is provided with a limiting block 17.

[0038] In the preferred embodiment, the limiting block 17 is integrally connected with the rotating rod 14, the limiting block 17 is rotatably connected with the fixing block 13 through the rotating rod 14, and the limiting block 17 is in the shape of a rectangle.

[0039] In the preferred embodiment, the outer side wall of the purification tank 1 is provided with a supporting block 16, and the surface of the supporting block 16 is provided with a through hole which is matched with the limiting block 17.

[0040] In the embodiment, the filter material 10 is easy to be blocked during the sewage treatment process. In order to replace the blocked filter material 10, the following steps are taken: first, rotate the limiting block 17 so that it is matched with the through hole on the supporting block 16, so that the limiting block 17 can be smoothly removed from the bottom end of the supporting block 16. Then, pull the sealing cover 11 upwards so that it is separated from the purification tank 1, thereby exposing the inside of the purification tank 1, facilitating the disassembly and replacement of the filter material 10. When fixing the sealing cover 11, the limiting block 17 is passed through the supporting block 16 and placed at the bottom end thereof, then the limiting block 17 is rotated to drive the rotating rod 14 to rotate in the fixing block 13, and at the same time, the limiting block 17 is misaligned with the through hole. Finally, the elasticity of the spring 15 is utilized to make the limiting block 17 tightly fit with the bottom end of the supporting block 16, thereby fixing the sealing cover 11, solving the problem that the filter material 10 is blocked and difficult to be treated after a long time.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
