Description

Technical Field

[0001] The invention relates to the technical field related to wastewater treatment, and in particular to a silane coating wastewater treatment process. Background Art

[0002] In the silane coating process, the prepared silane coating liquid first undergoes a self-hydrolysis reaction of silane molecules to generate corresponding silanols and organic alcohols. After that, dehydration condensation occurs between silanol molecules to generate long-chain macromolecular silanols similar to polymers. The macromolecular silanol adheres to the treated surface through hydrogen bonding, and then forms a stable chemical bond with the surface after heating and other treatments to complete the coating. In the silane coating process, wastewater will be generated due to waste liquid from silane coupling agent replacement and surface cleaning water after silane coating. The main pollutants in this type of wastewater are various silane coupling agent monomers, condensed macromolecular silanes, and corresponding organic alcohol byproducts produced by silane hydrolysis.

[0003] The current silane coating wastewater treatment process mainly includes pretreatment (removing larger suspended solids and impurities through grids and sedimentation tanks), pH adjustment, coagulation and sedimentation, oxidation treatment, biochemical treatment, membrane separation, reuse (after the deeply treated water reaches the reuse water quality standard, it is reused in the initial cleaning link of the production process) and other steps. In the oxidation process, the iron-carbon micro-electrolysis process is often used to electrolyze the wastewater without electricity, using the potential difference generated by the iron-carbon filler itself, so as to achieve the purpose of degrading organic pollutants. However, in the actual treatment of silane wastewater, there are still the following deficiencies:

[0004] First, the iron-carbon filler needs to be backwashed regularly to avoid the decrease in treatment efficiency caused by the packing compaction. However, during the flushing process, the normal operation of the reaction pool needs to be stopped and it can only be used normally after the treatment is completed.

[0005] Secondly, as the running time increases, the iron-carbon filler will be continuously consumed and needs to be replaced. When replacing the filler, the normal operation of the reaction pool also needs to be stopped and it can be used normally only after the replacement is completed. Summary of the invention

DETAILED DESCRIPTION

[0049] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0050] Example: Figure 1-6 As shown, a silane coating wastewater treatment process of the present invention comprises the following specific steps:

[0051] S1: Pretreatment, using the screen to intercept larger suspended solids, using the sedimentation tank to precipitate the suspended solids in the wastewater, and then the wastewater enters the regulating tank to adjust the pH value, and the wastewater flowing out of the regulating tank enters the sedimentation tank for precipitation;

[0052] S2: oxidation, using an oxidant to oxidize the pretreated water, oxidizing the silane into a water-soluble substance, and then performing a micro-electrolysis treatment using a micro-electrolysis treatment device after precipitation treatment;

[0053] S3: Biochemical treatment, using aerobic microorganisms to degrade organic matter;

[0054] S4: Filtration treatment, using a reverse osmosis membrane to filter the water obtained after biochemical treatment to obtain recycled water;

[0055] The micro-electrolysis treatment device used in the above treatment method includes a treatment pool 1, which is composed of an outer pool body 11 and a treatment chamber 12 fixed in the outer pool body 11, and an aeration component is provided in the outer pool body 11;

[0056] The reaction structure disposed in the processing chamber 12 is composed of a filler 6 filled with iron-carbon micro-electrolysis filler and a supporting mechanism 9 for supporting the filler 6;

[0057] A driving mechanism 3 for driving a supporting mechanism 9;

[0058] The support assembly 2 disposed in the outer tank body 11 is used to support the bearing mechanism 9;

[0059] A stepped platform 4 provided on one side of the treatment tank 1 and a flushing tank 5 for washing the iron-carbon micro-electrolysis filler;

[0060] A discharge pipe 7 is provided below the treatment tank 1 , and a drainage mechanism 8 is connected to the discharge pipe 7 .

[0061] Among them, Figure 6-7 and Figure 9-11 As shown, the bearing mechanism 9 includes a bearing frame 91 and a plurality of anti-stripping groups arranged on one side of the bearing frame 91. Both ends of the bearing frame 91 are provided with guide rods 1 94. A plurality of guide rods 2 93 are arranged side by side between the two guide rods 1 94. Guide channels 95 are provided on the upper and lower sides of the guide rods 1 94 and the guide rods 2 93. A connecting hole 96 is also provided on the guide rods 2 93.

[0062] The anti-slip module includes an anti-slip plate 97, a connecting seat 98 installed on one side of the supporting frame 91, and an anti-slip component 99 provided on the other side of the supporting frame 91 for fixing the anti-slip plate 97. One end of the anti-slip plate 97 is connected to the connecting seat 98 by an adjusting bolt 981, and a matching hole is provided at the other end of the anti-slip plate 97. The anti-slip component 99 includes a connecting seat 2 993 installed on the other side of the supporting frame 91, a support rod 997 installed in the connecting seat 2 993, and a pressing member 991 slidably provided outside the connecting seat 2 993. The pressing member 991 is provided with a screw thread that can pass through the connecting seat 2 993. A matching column 992 of a matching hole, a limit block 998 is provided at one end of the support rod 997, a T-shaped sliding plate 995 connected to the pressing piece 991 is provided on the outer sliding sleeve of the support rod 997, a connecting spring 996 is also provided on the outside of the support rod 997, and both ends of the connecting spring 996 are respectively connected to the limit block 998 and the T-shaped sliding plate 995, and one end of the connecting seat 2 993 is provided with a socket 999 for accommodating the matching column 992 to be inserted; the guide rod 1 94 has a guide channel 95 on each of the upper and lower sides, and the guide rod 2 93 has two guide channels 95 on each of the upper and lower sides; the adjusting bolt 981 adopts a handle bolt.

[0063] By means of the sliding cooperation between the guide bar 63 and the guide channel 95, the loader 6 is loaded into the bearing frame 91. The guide rod 1 94 and the guide rod 2 93 can not only cooperate with the bearing frame 91 to support the loader 6, but also separate the loaders 6, which is beneficial for the operator to adjust the number of loaders 6. After loosening the adjustment bolt 981, the pressing piece 991 is pulled, and the pressing piece 991 brings the matching column 992 out of the insertion hole 999. At the same time, the pressing piece 991 brings the T-shaped sliding plate 995 to move toward the limit block 998 and squeeze the connecting spring 996. After leaving an accommodating space between 1 and the connecting seat 2 993 for screwing in the anti-slip plate 97, screw the anti-slip plate 97 into the accommodating space so that the matching hole is aligned with the insertion hole 999, and then remove the force pulling the pressing member 991. The pressing member 991 is tightly pressed against the anti-slip plate 97 due to the elastic force of the connecting spring 996, and the matching column 992 is also inserted into the insertion hole 999 after passing through the matching hole. Finally, tighten the adjusting bolt 981 to further fix the anti-slip plate 97. The fixed anti-slip plate 97 can effectively prevent the loader 6 from sliding out of the supporting frame 91 when the supporting frame 91 rotates.

[0064] Specifically, a limiting hole groove coaxial with the insertion hole 999 and matching with the matching column 992 is opened on one side of the limiting block 998, and the matching column 992 is limited by the limiting hole groove.

[0065] Specifically, a sliding groove 994 that slidably cooperates with the T-shaped sliding plate 995 is provided at the bottom of the second connecting seat 993. The sliding groove 994 is provided to expose the T-shaped sliding plate 995, which is beneficial to the connection between the T-shaped sliding plate 995 and the pressing member 991.

[0066] Specifically, among them, Figure 8 As shown, the loader 6 is composed of a loading frame 61 and a mesh plate 62 for sealing the loading frame 61. Two guide bars 63 arranged face to face are arranged on both sides of the loading frame 61. The guide bars 63 slide in cooperation with the guide channels 95. A handle 64 is symmetrically arranged at one end of the loading frame 61. The mesh plate 62 can facilitate the contact between the filler and the wastewater. The handle 64 is conducive to the loading and unloading of the loader 6. Too much filler cannot be placed in the loader 6. A maximum of 80% of the filler can be loaded.

[0067] Among them, Figure 7 As shown, one side of the supporting frame 91 is connected to an arc-shaped connecting member 92 via a connecting column, and both sides of the arc-shaped connecting member 92 are smoothly connected to connecting parts 921, and a plurality of connecting through holes are provided on the connecting part 921. The arc-shaped connecting member 92 can fit more closely with the surface of the driving shaft 32, thereby making the connection more stable, and the connecting part 921 matches with the mounting flange 34, which can facilitate the installation of the supporting frame 91.

[0068] Among them, Figure 6 and Figure 7 As shown, the driving mechanism 3 includes a driving shaft 32 rotatably connected to the outer pool body 11, a reducer 33 arranged outside the outer pool body 11, and a stepper motor 31 connected to the input end of the reducer 33. One end of the driving shaft 32 passes through the outer pool body 11 and is connected to the output end of the reducer 33. Two symmetrically distributed mounting flanges 34 are provided on the outer wall of the driving shaft 32. The mounting flange 34 is penetrated by a mounting screw that can pass through the connecting through hole. The mounting flange 34 is connected to the connecting portion 921 through the cooperation of the mounting screw and the nut.

[0069] The driving shaft 32 is driven by the stepper motor 31 and the reducer 33. The driving shaft 32 drives the supporting frame 91 with the help of the arc-shaped connecting piece 92 to change the position of the supporting frame 91 loaded with the loader 6. The supporting frame 91 located in the processing chamber 12 is transferred to the outside of the processing tank 1 with the loader 6. The supporting frame 91 located outside the processing chamber 12 transfers the loader 6 filled with new filler or flushed filler to the processing chamber 12 to continue the micro-electrolysis treatment. The operator can remove the loader 6 that has been transferred outside the processing tank 1 to flush or replace the filler without stopping the processing tank. During the reaction, the driving mechanism 3 can rotate with the supporting frame 91 within the range of 0 to 90 degrees to shake the filler in the loader 6, thereby effectively avoiding the filler from becoming compacted.

[0070] Among them, Figure 3-Figure 5As shown, the support assembly 2 includes a driving motor 21 installed outside the outer pool body 11, a bidirectional lead screw 25 rotatably arranged in the outer pool body 11, two guide rods 22 fixedly installed in the outer pool body 11, and two L-shaped support bodies 24 for supporting the supporting frame 91. One end of the bidirectional lead screw 25 passes through the outer pool body 11 and is connected to the output shaft of the driving motor 21. A nut slide is provided on the bidirectional lead screw 25, and a support plate 23 for supporting the L-shaped support body 24 is fixedly connected to the outer shell of the nut slide. A guide through hole for accommodating the guide rod 22 to pass through is opened on the support plate 23. A buffer spring 26 is provided on the outer shell of the guide rod 22, and both ends of the buffer spring 26 are connected to the support plate 23.

[0071] The load-bearing frame 91 is supported by the L-shaped support body 24 to reduce the burden on the drive shaft 32. The bidirectional screw 25 is driven by the driving motor 21, and the nut slide drives the L-shaped support body 24 with the help of the support plate 23 to change the position of the L-shaped support body 24 to avoid the L-shaped support body 24 hindering the rotation of the load-bearing frame 91.

[0072] Specifically, a long sliding hole that slides with the L-shaped support body 24 is opened on the side panel of the processing chamber 12, and a sealing ring is arranged between the long sliding hole and the L-shaped support body 24. The arranged sealing ring improves the sealing performance and reduces the probability of wastewater entering the space between the inner wall of the outer tank body 11 and the outer wall of the processing chamber 12.

[0073] Among them, Figure 3 , Figure 4 and Fig.12 As shown, mounting holes 15 are provided at the four top corners of the bottom plate of the outer pool body 11 and the processing chamber 12, and the four mounting holes 15 are distributed in a rectangular shape; the mounting holes 15 are used to install the drain pipe 82, and the mounting holes 15 are sealed to the drain pipe 82 to prevent wastewater from flowing out from the gap between the mounting holes 15 and the drain pipe 82.

[0074] The drainage mechanism 8 is composed of a lifter 81 installed on the outer wall of the outer pool body 11, two drainage pipes 82 installed in the installation hole 15, and a T-shaped connecting pipe 84 connected to the drainage pipe 82. The piston rod of the lifter 81 is connected to a lifting bracket 87. The T-shaped connecting pipe 84 is located between the two drainage pipes 82. The T-shaped connecting pipe 84 is also connected to the discharge pipe 7 through a pipeline. A sealing plug 83 is provided in the drainage pipe 82. A connecting rod 85 connected to the lifting bracket 87 is provided at the bottom of the sealing plug 83. A partition 86 is also provided in the drainage pipe 82. A sliding through hole is opened on the partition 86 to slide with the connecting rod 85. In order to improve the sealing performance, a sealing rubber ring can also be provided at the connection between the connecting rod 85 and the sliding through hole to reduce the probability of wastewater leakage.

[0075] The drain pipe 82 is blocked by the sealing plug 83 to prevent untreated wastewater from entering the drain pipe 82, so that the reaction is more complete. After the reaction is completed, the lifting bracket 87 is driven by the lifter 81, and the sealing plug 83 is moved downward with the help of the connecting rod 85, so that the drain pipe 82 and the T-shaped connecting pipe 84 are connected to the processing chamber 12, so that the treated water can be discharged through the discharge pipe 7 after flowing through the drain pipe 82 and the T-shaped connecting pipe 84.

[0076] Among them, Figure 3-5 As shown, the aeration assembly includes an aeration pipeline 14 installed in the outer tank body 11, a connecting pipe penetrating the bottom plate of the processing chamber 12, and an aeration head 13 arranged in the processing chamber 12. The air inlet end of the aeration pipeline 14 penetrates the outer tank body 11 and extends to the outside thereof. Both ends of the connecting pipe are respectively connected to the aeration head 13 and the aeration pipeline 14. The air inlet end of the aeration pipeline 14 is connected to an aeration device (such as an aeration pump). The aeration device is started, and aeration operation is performed with the help of the aeration pipeline 14 and the aeration head 13. Aeration provides sufficient oxygen for the sewage, promotes the galvanic cell effect reaction, and at the same time, aeration has the effect of stirring and impacting the wastewater. The shear force of aeration can also timely update the surface of the iron-carbon filler, thereby improving the mass transfer efficiency of the sewage and the iron-carbon filler.

[0077] During operation, the stepper motor 31 and the reducer 33 drive the driving shaft 32, and the driving shaft 32 drives the carrying frame 91 with the aid of the arc-shaped connecting piece 92, so that the carrying frame 91 rotates with the loader 6 within the range of 0 to 90 degrees to shake the stuffing in the loader 6, thereby effectively avoiding the stuffing from hardening. When the stuffing needs to be flushed or replaced, the driving mechanism 3 is also used to drive the carrying frame 91, change the position of the carrying frame 91 loaded with the loader 6, and make the carrying frame 91 located in the processing chamber 12 with the stuffing rotate. The filler 6 is transferred to the outside of the treatment tank 1, and the carrying frame 91 located outside the treatment chamber 12 transfers the filler 6 filled with new filler or flushed filler into the treatment chamber 12 to continue the micro-electrolysis treatment. After that, the operator can climb to the top of the platform with the help of the steps on the step platform 4, and after the anti-dropping assembly 99 releases the restriction of the anti-dropping plate 97 on the filler 6, the filler 6 is pulled out of the carrying frame 91, and then the filler 6 is placed in the flushing tank 5 to flush the filler, or replace the filler;

[0078] After the carrying frame 91 is moved into the processing chamber 12, the bidirectional lead screw 25 is driven by the driving motor 21, and the nut slide uses the support plate 23 to drive the L-shaped support body 24 close to the carrying frame 91, and the L-shaped support body 24 is used to support the carrying frame 91.
