Le bior\u00e9acteur \u00e0 membrane (BRM) est une technologie de traitement de l'eau qui utilise un processus de s\u00e9paration par membrane pour remplacer le r\u00e9servoir de s\u00e9dimentation secondaire dans le processus traditionnel des boues activ\u00e9es. Dans la technologie traditionnelle de traitement biologique des eaux us\u00e9es, la s\u00e9paration des boues et de l'eau est g\u00e9n\u00e9ralement r\u00e9alis\u00e9e par gravit\u00e9 dans le r\u00e9servoir de s\u00e9dimentation secondaire, et l'effet de s\u00e9paration d\u00e9pend de la capacit\u00e9 de d\u00e9cantation des boues activ\u00e9es. La performance de d\u00e9cantation des boues d\u00e9pend des conditions de fonctionnement du bassin d'a\u00e9ration, et l'am\u00e9lioration de la performance de d\u00e9cantation des boues n\u00e9cessite un contr\u00f4le strict des conditions de fonctionnement du bassin d'a\u00e9ration, ce qui limite l'applicabilit\u00e9 de ce proc\u00e9d\u00e9. En raison des exigences de s\u00e9paration solide-liquide du bassin de s\u00e9dimentation secondaire, la concentration des boues ne peut \u00eatre \u00e9lev\u00e9e, ce qui limite le taux de r\u00e9action biochimique. La contradiction entre l'augmentation de la charge volum\u00e9trique et la r\u00e9duction de la charge de boues peut facilement conduire \u00e0 l'expansion des boues, ce qui se traduit par une qualit\u00e9 d'effluent inf\u00e9rieure \u00e0 la norme.
\nLa technologie MBR combine les deux, am\u00e9liorant consid\u00e9rablement l'efficacit\u00e9 de la s\u00e9paration solide-liquide et augmentant le taux des r\u00e9actions biochimiques. En m\u00eame temps, en r\u00e9duisant la valeur F\/M, la quantit\u00e9 de boue g\u00e9n\u00e9r\u00e9e est fortement r\u00e9duite, ce qui r\u00e9sout fondamentalement bon nombre des contraintes des proc\u00e9d\u00e9s traditionnels \u00e0 boues activ\u00e9es. Les BRM peuvent \u00eatre divis\u00e9s en deux formes : externes et immerg\u00e9es.<\/p>","protected":false},"excerpt":{"rendered":"
