Description
Technical Field

Background
The MABR (Membrane Aerated Biofilm Reactor) membrane aeration biological membrane reactor is a sewage treatment device utilizing the synergistic effect between an oxygen selective ventilation membrane and an attached growth biological membrane, and adopts the ventilation membrane to transfer oxygen to the biological membrane attached to the surface of the membrane, and simultaneously, matrixes such as ammonia nitrogen, organic matters and the like are diffused into the biological membrane from sewage, while the MABR membrane reactor is in an integral anoxic large environment, and the aerobic biological membrane (taking nitrifying bacteria as dominant bacteria) grown by the MABR membrane and denitrifying bacteria growing in suspension in the external and anoxic environments realize synchronous nitrification and denitrification to strengthen the removal of ammonia nitrogen and total nitrogen in the sewage. When sewage flows around the MABR membrane, pollutants in the water body enter the biological membrane under the actions of concentration difference driving, microorganism adsorption and the like, and are utilized by microorganisms through biological metabolism and proliferation, so that the pollutants in the water body are assimilated into microbial cells and fixed on the biological membrane or decomposed into inorganic metabolites, and the water body is purified and recycled.
Existing MABR component forms and characteristics: (1) The membrane component which adopts the hollow fiber membrane as a core element has smaller membrane wire diameter, usually about 1 mm; because the membrane wires are soft and have certain toughness, the membrane wires are generally vertically arranged, and one curtain of membrane is formed by glue sealing and arranging dozens or even hundreds of membrane wires at two ends. Compressed air is fed from the bottom of the membrane wire, oxygen in the air is permeated through micropores of the membrane wire in a bubble-free aeration mode to supply oxygen for microorganisms, and tail gas is intensively discharged into the air from the upper end of the membrane wire. However, the hollow fiber membrane component has the problems of high production cost and easy broken membrane wires. (2) The membrane component adopting the heavy ion microporous membrane as the core element has the advantages that the diameter of the membrane tube is larger (6 mm), the membrane tube in the component is horizontally and transversely arranged, the toughness is stronger, the wire breakage condition is not easy to occur, oxygen in the air is permeated through micropores of the heavy ion microporous membrane tube in a bubble-free aeration mode to supply oxygen for microorganisms, and tail gas is intensively discharged into the air from the other end of the membrane tube.

Therefore, the conventional heavy ion microporous membrane MABR component has insufficient number of biofilm microorganisms attached to the membrane tube, and sewage and the biofilm cannot be fully contacted, so that the pollutant removal efficiency in the sewage is difficult to further improve; because the membrane tubes of the conventional heavy ion microporous membrane assembly are horizontally and transversely arranged, when the bottom of the membrane assembly is not purged, mud is easy to accumulate on the upper side of the membrane tubes, oxygen in air in the membrane tubes is influenced to dissolve into water from micropores, the distance between the upper layer and the lower layer of the membrane tubes is too close (generally less than 10 mm), and when an abnormal condition occurs, the abnormal occurrence position cannot be judged. And a portion of the inner membrane tubes are substantially less exposed to contaminants than biofilm growth, resulting in an undesirable efficiency.
(2) High operation and maintenance cost
The conventional heavy ion microporous membrane component is characterized in that the front and rear surfaces are filled with membrane tube glue, 200-300 membrane tubes are uniformly filled and sealed, if one or more membrane tubes are broken or damaged, the membrane tubes cannot be independently taken out for replacement, the component is difficult to overhaul and maintain, and the whole replacement of the membrane component clearly greatly increases the operation and maintenance cost.
