Algúns malentendidos sobre o proceso MBR ②

Equipo: 2020-07-10 Accesos: 108

De verdade entendes a tecnoloxía MBR? Coñeces como usalo?



Nos últimos anos, o proceso MBR foi moi utilizado pola xente. O proceso MBR pode usarse en moitas aplicacións como a reutilización de augas recuperadas, a mellora dos estándares ambientais e o tratamento de dispersión das augas residuais. Como todos sabemos, a razón pola que o proceso MBR ten tantos usos xeneralizados débese principalmente ás súas excepcionais vantaxes como alta carga, longa idade de barro, alta eficiencia de apagado e pequena pegada.


Este artigo seguirá introducíndolle malentendidos sobre a aplicación do proceso MBR no tratamento de augas residuais.

 


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.
