Description

[0001] This application is a divisional application of the invention application with the application date of September 3, 2024, the Chinese application number of 2024112248656, and the invention name of "A kind of anti-blocking self-cleaning sewage ceramic membrane bioreactor". Technical Field

[0002] The invention relates to the technical field of sewage treatment, and in particular to a ceramic membrane bioreactor. Background Art

[0003] The sewage treatment process usually includes a series of physical, chemical and biological reactions, the purpose of which is to remove pollutants from the water and make it reach the standard for safe discharge or reuse. The main one is biological treatment, which uses microorganisms to decompose organic matter in sewage, which is usually achieved through the activated sludge method or biofilm method. In the activated sludge method, microorganisms are multiplied in large numbers in the aeration tank, consuming organic matter and converting it into carbon dioxide, water and cellular substances. In the biofilm method, microorganisms are cultivated on the filler to form a biofilm. When the sewage flows through, the microorganisms on the biofilm adsorb and decompose the organic matter.

[0004] Among them, ceramic membrane wastewater treatment is an advanced wastewater treatment method that combines biological treatment and membrane separation technology. Combined with biological treatment technology, such as membrane bioreactor (MBR), ceramic membrane can provide an efficient solid-liquid separation environment, increase the biomass in the bioreactor, and improve wastewater treatment efficiency; however, as the wastewater is filtered, the ceramic membrane may capture and accumulate suspended particles, organic matter, inorganic salts and other impurities. If these substances are not cleaned in time, they may clog the membrane pores, and when treating liquids containing microorganisms, microorganisms may grow on the surface or inside the membrane to form a biofilm, resulting in a decrease in membrane flux and a decrease in the operating performance of the reactor;

[0064] The material changing component 71 switches the operation state according to the actual operation requirements;

[0065] First, the circulation pump 7111 is started, and the circulation pump 7111 performs negative pressure suction. At this time, the first electric valve 717 on the second input pipe 716 is in a closed state; the second electric valve 7110 at the upper end of the second output pipe 715 is in a closed state, and then the filler in the sewage will be connected to the sewage to be extracted and discharged downward through the bottom end of the second output pipe 715, and the filler will be collected by the collection net frame 72, while the sewage will pass through the collection net frame 72 and automatically introduced into the reaction chamber 43, so as to realize the extraction of the loaded filler;

[0066] When replacing, open the sealing cover 712, inject new load filler into the material changing barrel 711, and then seal the material changing barrel 711 again. At this time, the first electric valve 717 on the input pipe 1 714 is in a closed state, and the second electric valve 7110 at the lower end of the output pipe 2 715 is in a closed state. At this time, the sewage can be extracted through the suction pipe 719 and then injected into the material changing barrel 711. Under the action of water pressure, the new filler is pressed into the load room 9 to complete the injection of the new filler.

[0067] In this embodiment, the bearing assembly 81 includes a download plate 811, a spring 812, a support sheet 813, a guide member 814, and a pull rod 815. The bottom of the filter assembly 83 is equipped with the download plate 811. The download plate 811 is evenly distributed with guide openings 8111, and the guide openings 8111 correspond to the filter assembly 83. The guide openings 8111 are clamped with the guide member 814, and the pull rod 815 is installed through the guide member 814. The support sheet 813 is fixedly installed at the bottom of the pull rod 815, and the spring 812 is sleeved on the pull rod 815 between the guide member 814 and the support sheet 813.

[0068] The guide assembly 82 includes an upper loading plate 821, an outer rod 822, an inner rod 823, a connecting plate 824, and a scraper 825.

[0069] The downloading plate 811 and the loading plate 821 cooperate with each other to complete the loading operation of the filter assembly 83;

[0070] During this period, when the filter assembly 83 is separated, it needs to be lifted and lowered first. When rising, the download plate 811 and the upper loading plate 821 rise synchronously. Since the area of ​​the download plate 811 is larger than that of the upper loading plate 821, the positioning joint 86 on the download plate 811 will rise synchronously with the rise until the positioning joint 86 and the positioning plate 87 are docked, and the positioning plate 87 is used to limit the download plate 811. However, the upper loading plate 821 continues to rise, and the pull rod 815 will squeeze the spring 812 through the supporting piece 813 as it rises, causing the spring 812 to enter a compressed state, so that the filter assembly 83 is separated from each other. When the filter assembly 83 is misaligned, the guide member 814 will perform auxiliary guidance in the guide port 8111, so that the lower half of the filter assembly 83 will be completely exposed, waiting for the flushing operation;

[0071] When lifting, the outer sleeve rod 822 and the inner sleeve rod 823 are telescoped to avoid interference;

[0072] When misaligned, the upper loading plate 821 will synchronously drive the outer sleeve rod 822 and the inner sleeve rod 823 to move, and the connecting plate 824 and the scraper plate 825 will move synchronously, and the scraper plate 825 will be used to scrape the dirt on the bottom surface of the reaction chamber 43, causing the dirt to be scraped into the collection tank 45 and wait for extraction.

[0073] In this embodiment, the filter assembly 83 includes a lower shell 831, a first ceramic filter membrane 832, a lower docking piece 833, an upper shell 834, a second ceramic filter membrane 835, a second water inlet 23, and an upper docking piece 837. The lower shell 831 is docked with the top of the download plate 811, and the second water inlet 23 that runs through the download plate 811 is docked with the bottom of the lower shell 831. The lower docking piece 833 is fixedly installed on the top of the lower shell 831, and the upper docking piece 837 is docked with the lower docking piece 833.

The top of the clean water branch pipe 841 is docked with the clean water main pipe 842.

[0075] The second ceramic filter membrane 835 and the first ceramic filter membrane 832 are mounted together through their respective housings, and the sewage enters the second ceramic filter membrane 835 and the first ceramic filter membrane 832 through the second water inlet 23 for filtration and purification. After passing through the second ceramic filter membrane 835 and the first ceramic filter membrane 832, the sewage is dialyzed, and the purified water enters the gap between the membrane and the housing, and is discharged through the clean water branch pipe 841 and the clean water main pipe 842, and the clean water main pipe 842 is installed and connected to an external water pump;

[0076] The sewage will be circulated and discharged through the sewage outlet 844. The sewage outlet 844 is connected to a pump through a pipeline. The pump then introduces the extracted sewage into the reaction chamber 43 again to achieve a cyclic operation.

[0077] When the second ceramic filter membrane 835 is separated from the first ceramic filter membrane 832, the lower docking piece 833 and the upper docking piece 837 are separated. When backwashing is performed, the first flushing joint 104 and the second flushing joint 105 are respectively docked with the lower shell 831 and the upper shell 834 to perform backwashing operations;

[0078] The one-way water injection port 845 is a water injection port, and a one-way water inlet valve is arranged on the water injection port. When filtering sewage, the one-way water injection port 845 on the liquid guiding square tube 843 can only allow one-way water inlet and cannot allow drainage.
