Nekaj ​​nesporazumov v zvezi s postopkom MBR ③

Čas: 2020-07-19 Zadetkov: 90

Ali resnično razumete tehnologijo MBR? Ali ste seznanjeni s tem, kako ga uporabljati?



V zadnjih letih so postopek MBR ljudje zelo uporabljali. Postopek MBR se lahko uporablja v številnih aplikacijah, kot so ponovna uporaba obnovljene vode, izboljšanje okoljskih standardov in disperzijsko čiščenje odpadnih voda. Kot vsi vemo, je razlog, da ima postopek MBR tako široko uporabo, predvsem zaradi njegovih izjemnih prednosti, kot so velika obremenitev, dolga starost blata, visoka učinkovitost zapiranja in majhen odtis.


Ta članek vas bo še naprej seznanjal z nesporazumi glede uporabe postopka MBR pri čiščenju odpadnih vod.

 

Misunderstanding 3: MBR process does not require sludge discharge

 

Correct interpretation: Due to the excellent retention effect of membrane filtration, the activated sludge in the MBR process can reach a higher concentration, and the separation of hydraulic retention time and sludge age can be achieved without considering the effect of sludge concentration on the effluent.

 

However, this advantage only enhances the biochemical play space, does not affect the effluent and cannot be used as a reason to support sludge discharge. The problem of sludge discharge still needs to be returned to activated sludge.

 

If the sludge is not discharged, the activated sludge will have aging problems, which will affect the biochemical performance and affect the aeration.

 

Therefore, the MBR process in the project can indeed reduce sludge, but sludge is also required.
