[0002] With the increase of environmental awareness and the importance of environmental protection, sewage treatment has received more and more attention. Sewage treatment processes are often diverse, among which oxidation treatment of sewage is one of the commonly used treatment methods. For example, a mixed gas of oxygen and ozone is filled into the sewage, oxidized, and then introduced into the sedimentation chamber for sufficient oxidation, sedimentation and separation. After that, the separated water is pumped out to the next treatment process through a water pump. However, when extracting water, it is easy to disturb the water body and cause the diffusion of impurities, so that the extracted water quality does not meet the standard. However, if a filter is set up for filtration and isolation, the filtration efficiency will be affected due to rapid clogging of sludge.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the implementation mode of the utility model clearer, the technical scheme in the implementation mode of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation mode of the utility model. Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Depend on Figures 1 to 3As shown, an embodiment of the utility model provides a sludge separation device of a sewage oxidation device, including an oxidation device 1, wherein the oxidation device 1 includes a water inlet cylinder 2, and an oxidation chamber 3 is arranged at one end of the water inlet cylinder 2 close to the water inlet, wherein the oxidation chamber 3 is provided with a device or air pipe (not shown in the figure) for introducing oxidation gas into the sewage, and there are many oxidation methods, which will not be elaborated here. Preferably, a primary sedimentation chamber 4 and a secondary sedimentation chamber 5 are also provided in the water inlet cylinder 2; it also includes a first pump 6, a second pump 7 and a transfer cylinder 8; the input end of the second pump 7 is connected to the secondary sedimentation chamber 5, and the output end is connected to the inside of the transfer cylinder 8; the input end of the first pump 6 is connected to the inside of the transfer cylinder 8, and the output end is connected to the primary sedimentation chamber 4; a detector 24 for detecting the concentration of suspended solids in the internal water quality is provided on the transfer cylinder 8; the primary sedimentation chamber 4 is connected to the oxidation chamber 3, and a partition 9 is provided between the secondary sedimentation chamber 5 and the primary sedimentation chamber 4, and a through hole 10 is provided at the center position of the partition 9; a separation filter 11 is also provided in the secondary sedimentation chamber 5, and the open end of the separation filter 11 is connected to the through hole 10; a cleaning door 12 is provided at the end of the secondary sedimentation chamber 5 away from the water inlet, and the cleaning door 12 can be connected to the outside after opening, so as to facilitate cleaning of the interior. After being oxidized by the oxidation chamber 3, the sewage will enter the primary sedimentation chamber 4 with a large water flow fluctuation. At this time, as the water level in the primary sedimentation chamber 4 rises, the water flow gradually slows down, and most of the sludge is deposited in the primary sedimentation chamber 4. The sewage with smaller suspended matter enters the separation filter 11 in the secondary sedimentation chamber 5 from the through hole 10, and the impurity concentration is further reduced under the filtration of the separation filter 11. Since most of the impurity deposition has been completed in the primary sedimentation chamber 4, the separation filter 11 needs to filter less impurities and less sediment. The filtration efficiency will only be reduced after long-term use. At this time, the filtration efficiency can be restored by simply opening the cleaning door 12 and removing the separation filter 11 for cleaning. Furthermore, when the first pump 6 draws the water in the secondary sedimentation chamber 5 into the transfer drum 8, the detector 24 detects the concentration of suspended solids in the water body. If it does not meet the standard, it can be pumped into the primary sedimentation chamber 4 by the second pump 7 for re-deposition, wherein the primary sedimentation chamber 4 is also provided with a reflux pipe 17, and a second control valve 16 is connected between the input end of the reflux pipe 17 and the output end of the first pump 6 to control the reflux; the output end of the reflux pipe 17 extends to the lower part of the primary sedimentation chamber 4, which will not affect the higher water level concentration, so as to perform reflux sedimentation. When the standard is met, the water in the transfer drum 8 flows to the water outlet drum below, and other treatment processes can be carried out.

[0022] Furthermore, when the detector 24 detects that the filter does not meet the standard, it also indicates that the filtering efficiency of the separation filter 11 is low and needs to be cleaned or repaired and maintained.

[0023] Furthermore, a sewage outlet 13 is provided at the bottom of the primary sedimentation chamber 4; a high-pressure spray head 14 is also provided in the primary sedimentation chamber 4, and a first control valve 15 is connected between the input end of the high-pressure spray head 14 and the output end of the first pump 6. When it is necessary to clean the first sedimentation chamber, the sewage outlet 13 is opened and the high-pressure spray head 14 is used to flush the side wall and the bottom of the first sedimentation chamber, thereby flushing away the sludge from the sewage outlet 13.

[0024] Preferably, the separation filter screen 11 is cylindrical, which can greatly increase the area of ​​the filter screen 21 and improve the filtering efficiency.

[0025] Preferably, a support frame 18 is further provided in the secondary sedimentation chamber 5, one end of the support frame 18 is fixedly connected to the partition 9, and the other end is fixedly provided on the inner wall of the secondary sedimentation chamber 5 away from the partition 9; the separation filter 11 is slidably connected to the support frame 18. The support frame 18 can not only stably support the separation filter 11 so that it can filter stably, but also the sliding installation of the separation filter 11 can make the installation and removal of the separation filter 11 faster, so that it can be quickly cleaned and maintained.

[0026] Furthermore, the support frame 18 includes a plurality of support rods 19, which are arranged at intervals on the outer peripheral side of the separation filter 11. Correspondingly, the separation filter 11 includes a frame 20 and a filter 21, and the frame 20 ensures the structural strength of the separation filter 11, and the frame 20 is slidably connected with the support rods 19 for support, installation and disassembly.

[0027] Preferably, the partition plate 9 is provided with an annular groove 22, a sealing ring is provided in the annular groove 22, and the opening end of the separation filter 11 is adapted to be plugged into the annular groove 22. During installation, by inserting the opening end of the separation filter 11 into the annular groove 22, it is ensured that the water at the through hole 10 can enter the separation filter 11, and will not directly leak into the secondary sedimentation chamber 5.

[0028] Preferably, a support frame 23 is fixedly provided at the inner end of the cleaning door 12. By providing the support frame 23, when the cleaning door 12 is closed, the frame 20 at the end of the separation filter 11 is abutted by the bottom frame, and the separation filter 11 is tightly abutted in the annular groove 22, thereby ensuring the stability and "sealing" effect of the separation filter 11 after installation.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
