Di derbarê Pêvajoya MBR de Hin Têgihiştin

Time: 2020-07-19 Hits: 90

Do you really understand MBR technology? Are you familiar with how to use it?



Di van salên dawî de, pêvajoya MBR ji hêla mirovan ve pir tête bikar anîn. Pêvajoya MBR dikare di gelek serîlêdanan de were bikar anîn wek mînak ji nû ve karanîna ava vegerandî, baştirkirina pîvanên jîngehê, û dermankirina belavkirina ava şile. Wekî ku em hemî dizanin, sedema ku pêvajoya MBR gelek karanînên berbelav heye bi taybetî ji ber avantajên wê yên berbiçav ên wekî barkirina bilind, temenê gulê dirêj, karîgeriya bilind a vemirandinê û şopa piçûk e.


Ev gotar dê di derheqê sepandina pêvajoya MBR-ê de di dermankirina kanalîzasyonê de ji we re bi têgihîştinan bide nasandin berdewam bike.

 

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.



In the next article, we will continue to introduce the misunderstandings of the MBR process.
