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



Ni awọn ọdun aipẹ, ilana MBR ti ni lilo pupọ nipasẹ awọn eniyan. Ilana MBR le ṣee lo ni ọpọlọpọ awọn ohun elo bii atunlo omi ti a gba pada, ilọsiwaju ti awọn iṣedede ayika, ati itọju pipinka ti omi apanirun. Gẹgẹbi gbogbo wa ṣe mọ, idi idi ti ilana MBR ni ọpọlọpọ awọn lilo ibigbogbo ni o kun nitori awọn anfani titayọ rẹ gẹgẹbi fifuye giga, ọjọ pẹtẹ pẹ, ṣiṣe giga ti pipade, ati ifẹsẹtẹ kekere.


Nkan yii yoo tẹsiwaju lati ṣafihan fun ọ si awọn aiyede nipa ohun elo ti ilana MBR ni itọju omi omi.

 

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.
