Definitions
- the UASB (Upflow Anaerobic Sludge Bed) method is known as a high-speed anaerobic wastewater treatment method.
- This method is an anaerobic microorganism treatment method in which an anaerobic filamentous methane bacterium is entangled and a granulated, self-granulated microbial mass called granules having a diameter of about 1 to 5 mm and excellent sedimentation is held in a treatment apparatus.
- a feature of the UASB method is that the concentration of microorganisms is maintained at a high concentration by the microbial mass to enhance the treatment efficiency.
- a microbial mass such as granules is held in the lower layer portion of the reactor vessel to form a sludge bed, and the waste water is introduced into the sludge bed from the lower portion by an external pump and included in the wastewater.
- Biological treatment of organic substances, nitrogen compounds, etc. The biological treatment of wastewater generates various gases such as methane, carbon dioxide and nitrogen from the sludge bed. When the generated gas adheres to the microbial mass as bubbles, the microbial mass lifts the microbial mass and ascends in the reactor vessel. Bubbles and bubble-adhering microbial masses generated from the sludge bed rise along the lower surface of the spiral plate.
- the rising air bubbles 10 do not adhere to the microbial mass 11 and do not rise again, and the sedimentation can be improved. That is, the air bubbles 10 and the microbial mass 11 from which the air bubbles 10 are separated are moved opposite to each other across the spiral plate 3 as the air bubbles 10 and the moving direction 13 of the air bubbles attached microbial mass 12 and the moving direction 14 of the microbial mass 11 Because there is no contact.
- the width of the baffle plate 15 attached to the spiral plate 3 is the same as that of the spiral plate 3 and is installed without a gap between the column 2 and the reactor vessel 1.
- the free end of the baffle plate 15 may be in the form of a saw, and the air bubbles 10 and the bubble-adhering microorganism mass 12 stored at one end by the baffle plate 15 are improved little by little by improving the microorganism mass 11 over the baffle plate 15. Can also be suppressed. It is desirable that the above-mentioned phenomenon (the phenomenon that the air bubbles 10 and the bubble-adhering microorganism mass 12 exceed the baffle plate 15) occur in a chained manner and can be achieved by adjusting the storage amount of the baffle plate 15.
