Na u hlile u utloisisa theknoloji ea MBR? Na u tloaetse mokhoa oa ho e sebelisa?



Lilemong tsa morao tjena, ts'ebetso ea MBR e sebelisitsoe haholo ke batho. Ts'ebetso ea MBR e ka sebelisoa lits'ebetsong tse ngata joalo ka tšebeliso ea metsi a bokelletsoeng, ntlafatso ea maemo a tikoloho le kalafo ea metsi a litšila. Joalokaha bohle re tseba, lebaka leo ka lona ts'ebetso ea MBR e nang le ts'ebeliso e mengata hakana e bakoa haholo ke melemo ea eona e ikhethang joalo ka mojaro o moholo, nako e telele ea seretse, ts'ebetso e kholo ea shutoff, le bolo e nyane ea maoto.


Sengoloa sena se tla tsoela pele ho u tsebisa ho se utloisisane mabapi le ts'ebeliso ea ts'ebetso ea MBR kalafong ea metsi a litšila.

 


Misunderstanding 2: Once MBR is used, the effluent quality can be guaranteed.

 

Correct interpretation: The MBR process is essentially a combination of activated sludge method and membrane filtration. It is based on the traditional activated sludge method and replaces the secondary settling tank with membrane filtration.

 

Through this technology, it can bring the advantages of good interception effect and high sludge concentration. But this does not mean that once the MBR process is used, all sewage can be treated.

 

For the removal of pollutants, membrane filtration has a very obvious effect on SS, while the removal of organic matter still depends on the biodegradability of activated sludge and organic matter.

 

For sewage with poor biodegradability, MBR technology has limited effect. For wastewater that has been fully biochemically treated at the front end, the role of MBR technology is also limited.



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