Xi nuqqas ta 'ftehim dwar il-Proċess MBR ③

Ħin: 2020-07-19 Viżti: 70

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



F'dawn l-aħħar snin, il-proċess MBR intuża ħafna min-nies. Il-proċess MBR jista 'jintuża f'ħafna applikazzjonijiet bħal użu mill-ġdid ta' ilma rkuprat, titjib ta 'standards ambjentali, u trattament ta' tixrid ta 'ilma mormi. Kif nafu lkoll, ir-raġuni għaliex il-proċess MBR għandu użi tant mifruxa huwa prinċipalment minħabba l-vantaġġi eċċellenti tagħha bħal tagħbija għolja, età twila ta 'tajn, effiċjenza għolja ta' għeluq, u impronta żgħira.


Dan l-artikolu ser ikompli jintroduċi inti għal nuqqas ta 'ftehim dwar l-applikazzjoni tal-proċess MBR fit-trattament tad-drenaġġ.

 

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.
