Kèk Malantandi sou Pwosesis MBR ③

Tan: 2020 07--19 Frape: 90

Èske ou reyèlman konprann teknoloji MBR? Èske ou abitye avèk kouman yo sèvi ak li?



Nan dènye ane yo, pwosesis MBR la te lajman itilize pa moun. Pwosesis MBR la ka itilize nan anpil aplikasyon tankou réutilisation de dlo récupérées, amelyorasyon de normes anviwònman, ak dispèsyon tretman Des. Kòm nou tout konnen, rezon an pou kisa pwosesis la MBR gen anpil itilizasyon toupatou se sitou akòz avantaj eksepsyonèl li yo tankou chaj segondè, laj labou long, efikasite segondè nan fèmen, ak anprint ti.


Atik sa a ap kontinye entwodui ou nan Malantandi sou aplikasyon an nan pwosesis la MBR nan tretman dlo ize.

 

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.
