DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a wastewater treatment device for an agarose enzymatic degradation process, comprising a water storage buffer tank 1, a sedimentation tank 2 and a water pump 4, wherein the water storage buffer tank 1 is connected with a water inlet pipe 3, and the inner cavity of the sedimentation tank 2 is vertically and sequentially provided with a first partition 5, a second partition 6 and a third partition 7 to separate the sedimentation tank 2 into a first sedimentation bin, a second sedimentation bin, a third sedimentation bin and a fourth sedimentation bin, the water inlet of the water pump 4 is connected with the drain outlet of the water storage buffer tank 1, and the water outlet is connected with a water pipe extending into the first sedimentation bin.

[0021] After the sewage discharged from the test area is collected in the main pipeline, it is controlled by a valve and does not enter the sewage pipeline, but enters the water inlet pipe 3, and is discharged into the water storage buffer tank 1 through the water inlet pipe 3 for storage. A water level sensor may be provided in the water storage buffer tank 1, and the equipment is equipped with a control system. When it is detected that the water storage volume reaches a certain amount, the control system controls the water pump 4 to work and discharge the sewage into the first sedimentation bin for sedimentation treatment.

[0022] The water storage buffer tank 1 is an open box structure, and the color, smell and temperature of the sewage can be observed.

[0023] Overflow ports are respectively provided on the first partition plate 5, the second partition plate 6 and the third partition plate 7, and the heights of the multiple overflow ports are gradually reduced. A drainage pipe 8 is connected to the middle and upper part of the side wall of the fourth sedimentation bin.

[0024] The height of the plurality of overflow ports is gradually reduced to prevent the supernatant in the subsequent settling bin from flowing back into the preceding settling bin. The height of the drain pipe 8 is lower than the height of the lowest overflow port.

[0025] After the sewage is discharged into the first sedimentation tank, the temperature of the original sewage is reduced, and the agarose in the sewage can be precipitated as solids and naturally settle to the bottom. After the sewage level reaches a certain height, the upper clear liquid flows from the overflow port into the second sedimentation tank for secondary sedimentation. At this time, the sewage temperature is further reduced, and solids continue to precipitate. This is repeated, and finally, after four sedimentations, the wastewater without solids is discharged from the drain pipe 8 and discharged into the municipal sewage network.

[0026] The bottom of the side walls of the first sedimentation bin, the second sedimentation bin, the third sedimentation bin and the fourth sedimentation bin are all provided with sewage outlets 9, and sealing covers are provided on the sewage outlets 9. The sewage outlets 9 are closed during normal treatment, and can be opened after use to allow the precipitated fixed matter to flow out with the sewage in the lower layer.

[0027] The sewage and residues settled at the bottom of each sedimentation tank will be regularly collected and treated through the sewage outlet.

[0028] The cleaning assembly includes a top plate 11, a fixing rod 12, a collecting net bucket 13 and a scraper 17. The top plate 11 is detachably arranged on the top of the first partition 5. There are two fixing rods 12, which are fixedly connected to the bottom of the top plate 11 at intervals and extend downward to the first sedimentation bin and are close to the surface of the first partition 5. The collecting net bucket 13 is fixedly connected between the bottom ends of the two fixing rods 12 and is located below the filter screen 16. The scraper 17 is fixedly connected to the inner edge of the collecting net bucket 13 and is in contact with the surface of the first partition 5. The outer surface of the scraper 17 is a slope.

[0029] The sewage may contain floating pollutants, so a filter screen 16 is provided in the overflow port of the first partition plate 5 to intercept and filter the floating objects.

[0030] After a period of use, floating objects will adhere to the surface of the filter 16 on one side of the first sedimentation bin, causing the filter 16 to be blocked, affecting the normal filtering effect. Therefore, a cleaning component is provided to clean the filter 16 regularly.

[0031] The top plate 11 is snapped onto the top of the first partition 5 to fix the entire assembly. Two fixing rods 12 extend downward along the surface of the first partition 5 on one side of the first sedimentation bin. The two fixing rods 12 are respectively located on both sides of the filter screen 16 and do not affect normal water flow.

[0032] When installed in place, the collecting net bucket 13 and the scraper 17 are located below the filter screen 16. The cross section of the collecting net bucket 13 is a triangle or cone with a larger upper part and a smaller lower part, and the side is an inclined surface, which does not affect normal sedimentation and drainage.

[0033] The cross-section of the scraper 17 is a right triangle, one right-angled side is fixedly connected to the top of the collecting net bucket 13 on one side of the surface of the first partition 5, and the other right-angled side moves along the surface of the first partition 5. The pollutants on the surface of the filter screen 16 are scraped and cleaned through the beveled portion of the upper edge. At the same time, the beveled edge of the scraper 17 can guide the scraped pollutants to flow into the collecting net bucket 13.

[0034] The collecting net hopper 13 is made of a mesh material, which allows water to flow through and blocks and intercepts pollutants.

[0035] When the filter screen 16 needs to be cleaned, the top plate 11 is pulled upward, driving the fixing rod 12, the collecting net bucket 13 and the scraper 17 to move upward against the side of the first partition plate 5, and the pollutants are scraped off the filter screen 16 by the upper surface of the scraper 17 and fall into the collecting net bucket 13, and are taken out for cleaning.

[0036] After the cleaning is completed, the top plate 11 is held to move the fixing rod 12, the collecting net bucket 13 and the scraper 17 downward along the side of the first partition 5, so that the top plate 11 is snapped to the top of the first partition 5 for positioning, and the installation is completed.

[0037] In order to keep the scraper 17 always in contact with the surface of the filter screen 16 during the lifting and cleaning process, a limiting track can be set on the side of the first partition plate 5 to guide and limit the fixing rod 12 to ensure the installation and cleaning effect of the device.

[0038] A positioning block 14 is fixedly connected to the top of the first partition plate 5 , a positioning hole matched with the positioning block 14 is opened on the top plate 11 , and a handle 15 is fixedly connected to the top of the top plate 11 .

[0039] When the top plate 11 is installed downwardly in place, the positioning block 14 is inserted into the positioning hole to position and fix the top plate 11, thereby fixing the entire cleaning assembly, and the handle 15 is convenient for lifting the device.

[0040] It also includes an ultraviolet lamp car 10, and the lamp body of the ultraviolet lamp car 10 is located above the sedimentation box 2.

[0041] The top of the sedimentation tank 2 is open so that ultraviolet rays can irradiate the sewage. The ultraviolet lamp vehicle 10 can be set up above the sedimentation tank 2. It is equipped with an ultraviolet wavelength emitter with a wavelength of 253.7nm, which can effectively kill microorganisms in the tank. Personnel need to leave the site during work, and it is usually started at night to facilitate the discharge of the sewage after the microbial indicators in the sewage meet the standards the next day.

[0042] The bottoms of the inner cavities of the first sedimentation bin, the second sedimentation bin, the third sedimentation bin and the fourth sedimentation bin are respectively inclined and sunken toward the sewage outlet 9. When sewage is discharged through the sewage outlet 9, the sewage and solids in the lower layer can flow out of the sewage outlet 9 completely to avoid residue, and each sedimentation bin can be rinsed with clean water to ensure thorough cleaning.

[0043] In this equipment, after the sewage flows into the first sedimentation bin, it is initially cooled down, and the agarose in the water is not separated out to form solids and settles down. The upper clear liquid flows into the next sedimentation bin layer by layer from the overflow port. After multiple layers of sedimentation, the agarose in the water is completely precipitated and settled at the bottom of each sedimentation bin. Finally, the wastewater without fixed matter is discharged after being disinfected by ultraviolet light to kill microorganisms. The cleaning sewage is completely precipitated by natural cooling and sedimentation, so that the agarose dissolved at high temperature is precipitated from the water at low temperature. No acid, alkali, metal salt, neutralizer or organic solvent is added, and the sewage is less harmful.
