Vue d'ensemble :<\/strong> Le bior\u00e9acteur \u00e0 membrane MBR est un nouveau type de syst\u00e8me de traitement des eaux us\u00e9es qui combine la technologie de s\u00e9paration par membrane et la technologie de traitement biologique. En rempla\u00e7ant la technologie traditionnelle de traitement biologique par des composants membranaires dans le r\u00e9servoir de s\u00e9dimentation secondaire \u00e0 la fin, on maintient une concentration \u00e9lev\u00e9e de boues activ\u00e9es dans le bior\u00e9acteur, ce qui augmente la charge organique du traitement biologique, r\u00e9duisant ainsi l'empreinte des installations de traitement des eaux us\u00e9es, et on r\u00e9duit la quantit\u00e9 de boues r\u00e9siduelles en maintenant une faible charge de boues.La concentration de boues activ\u00e9es (MLSS) dans le syst\u00e8me de bior\u00e9acteur \u00e0 membrane peut \u00eatre augment\u00e9e jusqu'\u00e0 8000-10.000mg\/L, voire plus : L'\u00e2ge des boues (SRT) peut \u00eatre port\u00e9 \u00e0 plus de 30 jours.<\/p>\n

Processus technique<\/strong>
\nDans l'\u00e9tat anoxique du bassin A, les micro-organismes d\u00e9nitrifiants utilisent le nitrate comme source d'ammoniac pour restaurer et lib\u00e9rer l'azote mol\u00e9culaire (Nz) ou l'oxyde nitreux (NzO) afin de r\u00e9aliser la d\u00e9nitrification, tandis que la mati\u00e8re organique source de carbone se d\u00e9grade en substances acides, c'est-\u00e0-dire que le processus de d\u00e9nitrification est achev\u00e9. Dans l'\u00e9tat a\u00e9robie du bassin O, les bact\u00e9ries oxydant le nitrite convertissent l'azote ammoniacal des eaux us\u00e9es en nitrite, tandis que les bact\u00e9ries nitrifiantes convertissent le nitrite en nitrate, et la mati\u00e8re organique source de carbone s'oxyde en COz, c'est-\u00e0-dire que le processus de nitrification est achev\u00e9.<\/p>\n
