Voici quelques moyens d'optimisation courants :<br \/>\n1. Contr\u00f4le de l'environnement de l'oxyg\u00e8ne<br \/>\nR\u00e9aliser une distribution raisonnable de la zone a\u00e9robie, de la zone anoxique et de la zone ana\u00e9robie afin d'assurer le micro-environnement n\u00e9cessaire au processus d'\u00e9limination biologique de l'azote et du phosphore. Ajuster la quantit\u00e9 d'a\u00e9ration pour contr\u00f4ler le niveau d'oxyg\u00e8ne dissous (OD) dans la zone a\u00e9robie afin de promouvoir la r\u00e9action de nitrification. Assurer un temps de s\u00e9jour suffisant dans la zone anoxique pour faciliter la r\u00e9action de d\u00e9nitrification.<br \/>\n2. Contr\u00f4le de l'\u00e2ge des boues (SRT)<br \/>\nUne prolongation appropri\u00e9e de l'\u00e2ge des boues facilite la croissance des bact\u00e9ries nitrifiantes et le processus de nitrification. Pour l'\u00e9limination du phosphore, il est n\u00e9cessaire d'\u00e9quilibrer l'\u00e2ge des boues afin de maintenir un nombre suffisant de micro-organismes polym\u00e9risant le phosphore.<br \/>\n3. L'\u00e9quilibre nutritionnel<br \/>\nVeiller \u00e0 ce que les sources de carbone, d'azote et de phosphore soient suffisantes et \u00e9quilibr\u00e9es pour r\u00e9pondre aux besoins de l'\u00e9limination microbienne de l'azote et du phosphore. Ajuster le dosage des sources de carbone externes, telles que le m\u00e9thanol et l'acide ac\u00e9tique, en fonction de la qualit\u00e9 de l'eau influente afin de favoriser le processus de d\u00e9nitrification.<br \/>\n4. Strat\u00e9gie de retour et de d\u00e9charge<br \/>\nOptimiser la recirculation interne et le flux de retour des boues pour am\u00e9liorer l'efficacit\u00e9 de l'\u00e9limination des nitrates et des phosphates. Contr\u00f4ler l'\u00e9vacuation des boues pour maintenir l'\u00e9quilibre microbien dans le syst\u00e8me.<br \/>\n5. Pr\u00e9traitement \u00e0 l'entr\u00e9e<br \/>\n\u00c9liminer les mati\u00e8res en suspension et certains nutriments de l'eau influente par des m\u00e9thodes physiques ou chimiques (par exemple, s\u00e9dimentation, flottation) afin de r\u00e9duire la charge sur le syst\u00e8me biochimique.<br \/>\n6. Inoculation et s\u00e9lection des micro-organismes<br \/>\nInoculer des souches microbiennes pour une \u00e9limination efficace de l'azote et du phosphore afin d'am\u00e9liorer la capacit\u00e9 de traitement du syst\u00e8me. Favoriser la croissance de micro-organismes fonctionnels sp\u00e9cifiques par s\u00e9lection ou r\u00e9gulation biologique.<br \/>\n7. Contr\u00f4le de la concentration des boues<br \/>\nMaintenir une concentration ad\u00e9quate des boues (MLSS) afin d'am\u00e9liorer l'efficacit\u00e9 du traitement du syst\u00e8me.<br \/>\n8. Suivi et analyse<br \/>\nContr\u00f4ler r\u00e9guli\u00e8rement les indicateurs tels que l'azote et le phosphore, ainsi que les param\u00e8tres importants tels que le pH, l'OD, la temp\u00e9rature, etc. afin d'ajuster la strat\u00e9gie d'exploitation \u00e0 temps. Inspection miroir des boues pour observer les changements dans la phase microbienne afin d'\u00e9valuer le fonctionnement du syst\u00e8me.<br \/>\n9. Optimiser le d\u00e9roulement du processus<br \/>\nEnvisager l'adoption de proc\u00e9d\u00e9s de traitement avanc\u00e9s tels que le r\u00e9acteur discontinu s\u00e9quentiel (SBR), le foss\u00e9 d'oxydation, le bior\u00e9acteur \u00e0 membrane (MBR), etc. pour am\u00e9liorer l'effet de l'\u00e9limination de l'azote et du phosphore.<br \/>\n10. Faire face aux fluctuations de la charge d'eau d'alimentation<br \/>\nEn cas de fluctuation de la charge de l'eau d'alimentation, prendre les mesures correspondantes, telles que la dilution de l'eau d'alimentation \u00e0 forte charge, afin de prot\u00e9ger les micro-organismes de l'impact. Gr\u00e2ce \u00e0 l'application compl\u00e8te des moyens d'optimisation susmentionn\u00e9s, l'effet d'\u00e9limination de l'azote et du phosphore du syst\u00e8me biochimique peut \u00eatre consid\u00e9rablement am\u00e9lior\u00e9 pour parvenir \u00e0 un traitement plus efficace des eaux us\u00e9es.<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>L'am\u00e9lioration des syst\u00e8mes biochimiques affecte directement l'\u00e9limination de l'azote et du phosphore L'am\u00e9lioration de l'\u00e9limination de l'azote et du phosphore par le syst\u00e8me biochimique est l'un des principaux objectifs du traitement des eaux us\u00e9es.
