Guon misferstannen oer it MBR-proses ②

Time: 2020-07-10 hits: 108

Begripe jo echt MBR-technology? Binne jo bekend hoe't jo it brûke?



De lêste jierren is it MBR-proses breed brûkt troch minsken. It MBR-proses kin brûkt wurde yn in protte tapassingen lykas werbrûk fan weromwûn wetter, ferbettering fan miljeunormen, en fersprieding fan ôffalwetter. Lykas wy allegear witte is de reden wêrom't it MBR-proses safolle wiidferspraat gebrûk hat, benammen te tankjen oan syn opfallende foardielen lykas hege lading, lange modderleeftyd, hege effisjinsje fan ôfsluting, en lytse foetôfdruk.


Dit artikel sil jo trochgean mei yntroduksje fan misferstannen oer de tapassing fan it MBR-proses yn behanneling fan ôffalwetter.

 


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.
