Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment mechanism based on a high-salinity wastewater treatment system. Background Art

[0002] In the field of high-salt wastewater treatment, evaporation and crystallization technology evaporates the water in the wastewater by heating, thereby separating the salt from the water. Prior to this, the wastewater usually needs to be pre-treated to remove or reduce the impurity ions in the high-salt wastewater, and then enter the evaporation raw water tank for subsequent evaporation and crystallization treatment. Among them, the wastewater is de-siliconized and de-hardened in the coagulation sedimentation tank, and the muddy water is initially separated. The separated sewage usually also contains a certain amount of suspended solid particles, so it needs to be filtered. However, after a period of operation, the traditional sewage filter will accumulate a large amount of sludge that cannot be easily discharged. At this time, it needs to be shut down for manual flushing, which reduces the sewage filtration efficiency of the system.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and beneficial technical effect of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the present invention, not for limiting the present invention.

[0031] It should also be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0032] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0033] In an embodiment of the present invention, a sewage treatment mechanism 100 based on a high-salt wastewater treatment system is provided to treat sewage treated in a coagulation sedimentation tank 200 and collected in a water production tank 300, thereby improving the quality of the sewage for subsequent evaporation and crystallization treatment.

[0034] like Figure 1-Figure 2 As shown, the sewage treatment mechanism 100 based on the high-salt wastewater treatment system includes: a main water inlet pipeline 10, a filter water inlet pump 20, a fiber ball filter 30, a fiber ball filter water inlet or forward wash water inlet pipeline 40, a fiber ball filter water production pipeline 50, a fiber ball filter backwash water inlet pipeline 60, and a fiber ball filter backwash sewage discharge pipeline 70.

[0035] Specifically, one end of the main water inlet pipeline 10 is used to connect with the water production tank 300, and is provided with a main water inlet electric switch valve 11. The filter water inlet pump 20 is arranged in the main water inlet pipeline 10. The main water inlet electric switch valve 11 is used to realize the remote or automatic control on and off of the main water inlet pipeline 10, that is, the main water inlet electric switch valve 11 can be remotely opened in the control room, and then the filter water inlet pump 20 can be remotely started. At the same time, an automatic operation program can be written, and the filter water inlet pump 20 can be automatically started after the main water inlet electric switch valve 11 is automatically opened for a few seconds.

[0036] It should be noted that other electric switch valves also play a similar role as above, which is used to remotely or automatically control the opening and closing of the corresponding pipelines, and ultimately achieve the purpose of remotely or automatically controlling the operation of the drive pump. Among them, some pipelines in the figure do not show the corresponding drive pump structure, but they exist in the actual structure.

[0037] The fiber ball filter 30 includes a water inlet and outlet branch 31 at the top of the fiber ball filter and a water inlet and outlet branch 32 at the bottom of the fiber ball filter. It should be noted that the specific structure and filtering principle of the fiber ball filter 30 can refer to the prior art and will not be repeated here.

[0038] The two ends of the fiber ball filter water inlet or forward wash water inlet pipeline 40 are respectively connected to the fiber ball filter top water inlet and outlet branch 31 and the main water inlet pipeline 10, and are provided with a fiber ball filter water inlet or forward wash water inlet electric switch valve 41. Therefore, the sewage in the water production tank 300 can enter the fiber ball filter 30 through the main water inlet pipeline 10, the fiber ball filter water inlet or forward wash water inlet pipeline 40, and the fiber ball filter top water inlet and outlet branch 31 in sequence.

[0039] One end of the fiber ball filter water production pipeline 50 is connected to the fiber ball filter bottom water inlet and outlet branch 32, and is provided with a fiber ball filter water production electric switch valve 51. After the sewage is filtered in the fiber ball filter 30, the obtained water is discharged through the fiber ball filter bottom water inlet and outlet branch 32.

[0040] One end of the fiber ball filter backwash water inlet pipeline 60 is connected to the main water inlet pipeline 10, and the other end is connected to the fiber ball filter bottom water inlet and outlet branch 32, and the connection position is located between the fiber ball filter 30 and the fiber ball filter water production electric switch valve 51. The fiber ball filter backwash water inlet pipeline 60 is provided with a fiber ball filter backwash water inlet electric switch valve 61.

[0041] One end of the fiber ball filter backwash drainage pipeline 70 is connected to the water inlet and outlet branch 31 at the top of the fiber ball filter, and is provided with a fiber ball filter backwash drainage electric switch valve 71.

[0042] One end of the fiber ball filter forward wash and sewage discharge pipeline 90 is connected to the fiber ball filter bottom water inlet and outlet branch 32, and is provided with a fiber ball filter forward wash and sewage discharge electric switch valve 91.

[0043] Specifically, Figure 1 As shown, the normal water inlet process is: open the total water inlet electric switch valve 11, the fiber ball filter water inlet or forward wash water inlet electric switch valve 41 and the fiber ball filter water production electric switch valve 51, close the fiber ball filter backwash water inlet electric switch valve 61, the fiber ball filter backwash sewage discharge electric switch valve 71 and the fiber ball filter forward wash electric sewage discharge valve 91; the filter water inlet pump 20 drives the sewage in the water production tank 300 to pass through the total water inlet pipeline 10, the fiber ball filter water inlet or forward wash water inlet pipeline 40, the fiber ball filter top water inlet and outlet branch 31, the fiber ball filter 30 inside, the fiber ball filter bottom water inlet and outlet branch 32, the fiber ball filter water production pipeline 50, and the obtained water production enters the subsequent evaporation raw water tank from the fiber ball filter water production pipeline 50 for evaporation and crystallization treatment. Among them, the whole process is water inlet from the top and goes down, so that the fiber balls in the fiber ball filter 30 are compacted, and the fiber ball filter layer has the best filtering effect at this time.

[0044] like Figure 2 As shown, the backwash process: open the main water inlet electric switch valve 11, the fiber ball filter backwash water inlet electric switch valve 61 and the fiber ball filter backwash sewage discharge electric switch valve 71, close the fiber ball filter water inlet or forward wash water inlet electric switch valve 41, the fiber ball filter water production electric switch valve 51 and the fiber ball filter forward wash electric sewage discharge valve 91; the filter water inlet pump 20 drives the sewage in the water production tank 300 to pass through the main water inlet pipeline 10, the fiber ball filter backwash water inlet pipeline 60, the fiber ball filter bottom water inlet and outlet branch 32, the inside of the fiber ball filter 30, the fiber ball filter top water inlet and outlet branch 31, and the fiber ball filter backwash sewage discharge pipeline 70 in sequence, and discharge sludge and other impurities along with the sewage from the fiber ball filter backwash sewage discharge pipeline 70. Among them, sewage is changed to enter from the bottom and exit from the top, with water entering from the bottom (actually entering from the fiber ball filter water production pipeline 50, and the fiber ball filter water production electric switch valve 51 is in a closed state, but at this time the water in the fiber ball filter water production pipeline 50 can only enter the fiber ball filter 30 from the water inlet and outlet branch 32 at the bottom of the fiber ball filter), and the compacted fiber ball filter layer can be dispersed, so that impurities such as sludge can be dispersed, thereby cleaning the inside of the fiber ball filter 30, facilitating the next round of normal water intake process.

[0045] like Figure 3As shown, the forward washing process: close the fiber ball filter backwash water inlet electric switch valve 61, the fiber ball filter backwash sewage discharge electric switch valve 71 and the fiber ball filter water production electric switch valve 51, open the main water inlet electric switch valve 11, the fiber ball filter forward wash water inlet electric switch valve 41 and the fiber ball filter forward wash sewage discharge electric switch valve 91; the filter water inlet pump 20 drives the sewage in the water production tank 300 to pass through the main water inlet pipeline 10, the fiber ball filter forward wash water inlet pipeline 40, the fiber ball filter top water inlet and outlet branch 31, the fiber ball filter 30 inside, the fiber ball filter bottom water inlet and outlet branch 32, and the fiber ball filter forward wash sewage discharge pipeline 90 in sequence, and discharge the sludge and other impurities from the fiber ball filter forward wash sewage discharge pipeline 90 along with the sewage, so as to completely discharge the sludge flushed out during the above-mentioned backwashing process (backwashing is to discharge sewage from the top, and the sludge flushed out cannot be completely discharged), so as to avoid the impurities that are not discharged from affecting the subsequent water quality.

[0046] Furthermore, the mechanism also includes an aeration pipeline 80. A vortex air pump 81 is provided at one end of the aeration pipeline 80, and the other end is connected to a predetermined position of the fiber ball filter backwash water inlet pipeline 60. The vortex air pump 81 is used to transport air into the fiber ball filter backwash water inlet pipeline 60 through the aeration pipeline 80, so as to perform an air-water backwash process in which raw water and aeration are performed simultaneously in the fiber ball filter 30. The aeration pipeline 80 is also provided with an aeration electric switch valve 82.

[0047] It should be noted that if Figure 1-Figure 3 As shown, the use of this mechanism also includes a complete backwash and forward wash process: first carry out the above-mentioned backwash process with only raw water, flush with water, and after the above process is completed, perform the air-water backwash process with raw water and aeration at the same time, and finally perform the forward wash process again to completely drain the sludge flushed out during the above backwash process (backwashing is to discharge sewage from the top, and the sludge flushed out cannot be completely drained). The process can be carried out automatically, and the action time of the electric switch valve can be set to execute a certain flushing time.

[0048] Furthermore, the mechanism also includes a fiber ball filter filtration bypass 101. The two ends of the fiber ball filter filtration bypass 101 are respectively connected to the fiber ball filter water inlet or forward wash water inlet pipeline 40 and the fiber ball filter water production pipeline 50, so as to be arranged in parallel with the fiber ball filter 30. The fiber ball filter filtration bypass 101 is provided with a fiber ball filter filtration bypass electric switch valve 102. When the fiber ball filter 30 operates normally, the fiber ball filter filtration bypass electric switch valve 102 is closed. When the water production effect of the front-end reaction sedimentation tank is good and there is no need to use the fiber ball filter 30 for filtration again, or in other special circumstances (such as only sewage transfer is required), the fiber ball filter filtration bypass electric switch valve 102 will be opened and the fiber ball filter water inlet or forward wash water inlet electric switch valve 41 will be closed, so as to perform bypass operation.

[0049] In one embodiment, the end of the main water inlet pipeline 10 away from the water production tank 300 is also connected to a water pipe 103. The water pipe 103 is provided with a water branch pipe valve 104, and is used to supply water to a reserved water point. The reserved water point can be a drug dissolving device, etc., that is, this part of the sewage will flow back to the coagulation sedimentation tank 200 through the drug dissolving device of the drug dosing system. The water branch pipe valve 104 is used to control the on and off of the water pipe 103.

[0050] In one embodiment, the mechanism further includes a filter pump return line 105. One end of the filter pump return line 105 is connected to the end of the main water inlet line 10, and the other end is connected to the water production tank 300 or the front end of the main water inlet line 10, thereby forming a similar "parallel" structure with the filter water inlet pump 20. Part of the sewage pumped out by the filter water inlet pump 20 can be returned to the water production tank 300 or the front end of the main water inlet line 10 through the filter pump return line 105, thereby preventing the filter water inlet pump 20 from being blocked, thereby increasing the service life of the filter water inlet pump 20.

[0051] It should be noted that in order to make it easier for readers to distinguish the sewage flow direction of the normal water inlet process and the backwash process, some pipeline lines related to the backwash process in the attached figure are displayed with dotted lines, but this is not a specific limitation.

[0052] In summary, the sewage treatment mechanism 100 based on the high-salt wastewater treatment system provided by the present invention performs normal filtration of the sewage raw water through the water inlet process, and the sewage enters from the top and exits from the bottom to compact the fiber balls inside to achieve the best filtering effect; then the inside of the filter is flushed through the backwash and forward wash processes. During the backwash process, the sewage enters from the bottom and exits from the top to disperse the compacted fiber ball filter layer to disperse impurities such as sludge. The forward wash process can completely discharge the impurities and sludge dispersed during the backwash process to avoid the impurities that have not been discharged affecting the subsequent water quality. After the above process is executed, the automatic cleaning of the fiber balls is realized, and the subsequent filtering effect is guaranteed. The pipeline structure design is simple and exquisite, and the automatic switching of the water inlet process and the backwash and forward wash processes can be achieved through the remote control of the electric switch valve.

[0053] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
