[0001] The invention relates to the technical field of sewage, in particular to a garbage leachate membrane concentration deep treatment device and a treatment method thereof. Background Art

[0002] Membrane wastewater treatment refers to filtering water sources by selecting a membrane with a certain permeability. This process is a physical filtration process. During the entire filtration process, particles smaller than the membrane pore size can still pass through the membrane pores and enter the filtered water source.

[0003] At the same time, since the membrane filtration process is a physical filtration process, the tiny organic matter and particulate matter in the sewage are not filtered out, and a further filtration process is required, namely activated carbon filtration. Activated carbon can effectively remove residual chlorine, organic matter, odor and impurities in the water.

[0004] When using activated carbon, the water flow needs to maintain a certain flow rate. A flow rate that is too slow will cause the pores in the activated carbon to be clogged, and thus lose the filtering effect. A flow rate that is too fast will result in incomplete filtration of the water flow, and thus cause the water quality after filtration to deteriorate. Summary of the invention

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1

[0030] See also Figure 1-Figure 7 , A landfill leachate membrane concentration deep treatment device comprises a membrane treatment unit 1 and an activated carbon treatment unit 2. The membrane treatment unit 1 comprises a sewage pipe 11, in which a membrane group 12 is arranged. Sewage is introduced into the upper end of the sewage pipe 11 and flows out from the lower end of the sewage pipe 11 after being filtered by the module 12. The module 12 filters out particles larger than the membrane pores.

[0031] The activated carbon treatment unit 2 includes a mounting frame 26, which is divided into an upper mounting plate 262 and a lower mounting plate 263. An access port 21 is provided on the upper mounting plate 262, and the access port 21 is connected to the lower end of the sewage pipe 11, so that the sewage in the sewage pipe 11 filtered by the module 12 is passed into the activated carbon treatment unit 2 from the access port 21. A rotating chamber 211 is provided on the cross-section of the access port 21, and an adjusting plate 23 is rotatably arranged in the rotating chamber 211. The adjusting plate 23 can rotate to enter the access port 21 from one end of the cross section of the access port 21, so as to adjust the size of the access port 21, and the flow rate of the sewage flowing out of the access port 21 is adjusted by adjusting the diameter of the access port 21.

[0032] The activated carbon treatment unit 2 also includes a carbon storage part 22, a speed measuring unit 24, a drying unit 25 and a vibration device 27. The carbon storage part 22 is a circular barrel body, and a plurality of carbon storage chambers 221 are evenly distributed on the circular barrel body. Each carbon storage chamber 221 is independently isolated from each other. Mesh plates 222 are arranged on the upper and lower end surfaces of the carbon storage chamber 221. Activated carbon is loaded in the carbon storage chamber 221. The upper and lower ends of the carbon storage part 22 are limited by the upper mounting plate 262 and the lower mounting plate 263, and the carbon storage part 22 is rotatably arranged on the upper mounting plate 262 and the lower mounting plate 263. A power unit is arranged on the mounting frame 26. The power unit can drive the carbon storage part 22 to rotate at a uniform speed on the mounting frame 26, so that the carbon storage chambers 221 at different positions of the ring circulate at a uniform speed through the bottom of the access port 21.

[0033] The function of the regulating plate 23 is to maintain the flow rate of sewage flowing into the carbon storage chamber 221 below the inlet 21 within a set range. If the size of the carbon storage space below does not change, the initial speed of sewage flowing into the carbon storage space from the inlet 21 will meet the requirements. However, the flow rate will slow down after entering the carbon storage space, which will cause the pores in the activated carbon to be clogged and the filtering effect to be lost. Therefore, when the regulating plate rotates, the number of carbon storage chambers 221 that need to be connected to the inlet 21 is also reduced accordingly, thereby reducing the flow rate of sewage flowing into the carbon storage chamber 221 to meet the set requirements.

[0034] The carbon storage portion 22 rotates clockwise, and the adjustment plate 23 rotates counterclockwise when the opening of the control inlet 21 is reduced. The speed measuring unit 24 is arranged on the initial end of the inlet 21, so that when the inlet 21 is reduced, the speed measuring unit 24 can always measure the water flow speed of the sewage flowing through, and when the inlet 21 is reduced, the carbon storage chamber 221 entering the bottom of the inlet 21 is all new, so that the activated carbon can work efficiently and ensure the deep treatment result of the sewage.

[0035] In the initial state, the adjustment plate 23 is in a semi-extended state, so that the access port 21 is in a semi-open state. When the water pressure and / or flow rate of the sewage flowing into the sewage pipe 11 decreases, the sewage passing through the module 12 is reduced, thereby reducing the sewage flow through the access port 21, so that the flow rate detected by the speed measuring unit 24 is slowed down. At this time, the hollow unit of the treatment device controls the adjustment plate 23 to rotate counterclockwise, so that the opening of the access port 21 is reduced, thereby accelerating the flow rate of the sewage flowing out of the access port 21 and maintaining it within the set range.

[0036] When the water pressure and / or flow rate of the sewage flowing into the sewage pipe 11 increases, the amount of sewage passing through the module 12 increases, thereby reducing the flow of sewage through the inlet 21, and increasing the flow rate detected by the speed measuring unit 24. At this time, the hollow unit control adjustment plate 23 of the treatment device rotates clockwise, increasing the opening of the inlet 21, and slowing down the flow rate of the sewage flowing out of the inlet 21, so that it is maintained within the set range, thereby ensuring that the activated carbon can work efficiently.

[0037] A drying unit 25 is provided on the mounting frame 26, and the drying unit 25 includes a warm air pipe 251 and a warm air cover 252 for supplying warm air. A drying hole is provided on the upper mounting plate 262, and an ash outlet 261 corresponding to the drying hole is provided on the lower mounting plate 263. The warm air cover 252 is provided on the drying hole, and the warm air pipe 251 is connected with the warm air cover 252, so that the warm air can enter the carbon storage chamber 221 passing under the drying hole, and flow out downward from the ash outlet 261 after passing through the carbon storage chamber 221, so as to achieve the drying operation of the activated carbon passing through the carbon storage chamber 22. At the same time, since the activated carbon contains active substances, the drying temperature cannot be too high, so that the drying temperature is maintained between 30°C and 130°C.

[0038] The vibration device 27 is arranged in the ash dropping hole 261. The vibration device 27 is an electric vibrator. When it is not vibrating, it does not contact the mesh plate 222. When the vibrator is powered on to vibrate, the vibrator vibrates and then touches the mesh plate 222, causing the mesh plate 222 to vibrate together, thereby vibrating the activated carbon inside. Since the drying process is also being carried out at this time, the vibration accelerates the outflow of water in the activated carbon, accelerates the drying process, and at the same time makes the organic matter and impurities adsorbed on the activated carbon fall downward, thereby restoring a certain adsorption capacity of the activated carbon, regenerating the activated carbon immediately, and increasing the service life of the activated carbon.

[0039] Each carbon storage chamber 221 is provided with a water flow detector for recording the time when water flows through. The carbon storage portion 22 rotates at a uniform speed. When the carbon storage chamber 221 enters below the drying hole, the central control unit controls the vibration frequency of the vibration device 27 and the flow rate of the warm air pipe 251 according to the water flow time. The longer the water flow time, the faster the vibration frequency of the vibration device 27, and the faster the flow rate of the warm air in the warm air pipe 251, thereby accurately regenerating the activated carbon in each carbon storage chamber 221, so that the adsorption capacity of the carbon storage chamber 221 that subsequently circulates into the inlet 21 remains basically consistent.

[0040] Its working principle or usage is as follows: Sewage is introduced into the upper end of the water pipe 11, and flows out from the lower end of the sewage pipe 11 after being filtered by the module 12. The module 12 filters out particles larger than the membrane pores. The filtered sewage enters the activated carbon treatment unit 2 from the lower end of the sewage pipe 11 for deep sewage treatment.

[0041] The sewage enters the carbon storage part 22 which rotates at a uniform speed below through the inlet 21. The sewage passes through the carbon storage cavity 221 and is discharged from below after being adsorbed by the internal activated carbon, thus completing the deep treatment.

[0042] The activated carbon treatment unit 2 is also provided with a drying unit 25 and a vibration device 27. Through the coordinated operation of the two, the activated carbon in the carbon storage chamber 221 can recover a certain adsorption capacity, so that the activated carbon can be regenerated and the service life of the activated carbon can be increased.

[0043] Since the water pressure and flow rate of the sewage flowing into the sewage pipe 11 will change, which will in turn affect the adsorption capacity of the activated carbon, it is necessary to adjust the size of the inlet 21 and the number of corresponding carbon storage chambers 221 below through the adjustment plate 23, thereby controlling the flow rate of the sewage flowing into the corresponding carbon storage chamber 221.

[0044] However, due to the change in the size of the access port 21, the usage time of each carbon storage chamber 221 on the carbon storage part 22 will be different, and the water flow time is recorded by the water flow detector. When the carbon storage chamber 221 moves to the drying unit 25 and the vibration device 27 area, the cleaning degree of the activated carbon in the carbon storage chamber 221 is adjusted by changing the vibration frequency of the vibration device 27 and the flow rate of the warm air pipe 251, so that the carbon storage chamber 221 with a long working time is cleaned with high intensity, and the carbon storage chamber 221 with a short working time is cleaned with low intensity, so that each carbon storage chamber 221 can be restored to a basically consistent adsorption capacity, thereby improving the stability of the entire sewage deep treatment. Example 2

[0045] See also Figure 1-Figure 7 , compared with Example 1, the difference lies in the operation mode of the carbon storage unit 22, the drying unit 25 and the vibration device 27, and the rest are the same.

[0046] The carbon storage part 22 rotates one or several carbon storage chambers 221 at set intervals, so that the carbon storage part 22 rotates only after a certain period of time and is in a prohibited state for the rest of the time, so that the activated carbon can perform adsorption operations better.

[0047] At the same time, after the carbon storage chamber 221 rotates one or several angles of the carbon storage chamber 221, the drying unit 25 and the vibration device 27 start to work, and the central control unit controls the working time of the drying unit 25 and the vibration device 27 according to the water flow time in each carbon storage chamber 221, so that the longer the water flow time, the longer the working time of the drying unit 25 and the vibration device 27, and the shorter the water flow time, the shorter the working time of the drying unit 25 and the vibration device 27. After the working time is reached, the drying unit 25 and the vibration device 27 stop working.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
