The PMABR/TMABR technology of the invention is mainly different from the prior MABR technology in that:
1) the PMABR/TMABR technology is structurally different from the traditional MABR technology, the integration of the PMABR/TMABR technology is stronger, only one reactor is needed for the PMABR/TMABR, and the PMABR/TMABR technology does not need to be matched with other biochemical process sections, so that the design flow is simplified, and the engineering investment is saved; which must be combined with other conventional biochemical processing stages.
2) Compared with the prior MABR technology which adopts an organic hollow fiber membrane as a membrane material and the PMABR/TMABR technology which adopts a ceramic membrane as a membrane material, the ceramic membrane has longer service life and prolongs the membrane replacement period.
3) And for better film formation, the surface of the adopted ceramic membrane is subjected to tetrafluoro modification hydrophobic treatment, and a layer of tetrafluoro coating is coated on the surface of the ceramic membrane after the ceramic membrane is fired and formed.
