Actuellement, les proc\u00e9d\u00e9s les plus couramment utilis\u00e9s pour traiter les eaux us\u00e9es laiti\u00e8res sont l'oxydation biologique par contact, le traitement a\u00e9robie autonome, le traitement ana\u00e9robie + a\u00e9robie, et le proc\u00e9d\u00e9 SBR et ses versions am\u00e9lior\u00e9es.<\/p>\n\n\n\n
1. Oxydation biologique par contact : Cette m\u00e9thode consiste \u00e0 charger un mat\u00e9riau d'emballage dans un bior\u00e9acteur. Les micro-organismes adh\u00e8rent au mat\u00e9riau d'emballage, formant un biofilm \u00e0 sa surface, et purifient les eaux us\u00e9es par contact avec le biofilm. En raison de la DCO \u00e9lev\u00e9e des eaux us\u00e9es laiti\u00e8res, un processus d'oxydation par contact en deux \u00e9tapes est g\u00e9n\u00e9ralement utilis\u00e9. Cependant, cette m\u00e9thode n\u00e9cessite une grande quantit\u00e9 de mat\u00e9riaux d'emballage pour les grandes stations d'\u00e9puration, ce qui n'est pas pratique pour le transport et le chargement, et entra\u00eene des rejets de boues importants.<\/p>\n\n\n\n
2. Proc\u00e9d\u00e9 SBR et versions am\u00e9lior\u00e9es : Le proc\u00e9d\u00e9 SBR (Sequencing Batch Reactor) est largement utilis\u00e9. Le proc\u00e9d\u00e9 CASS est une am\u00e9lioration de la m\u00e9thode SBR, \u00e0 savoir le proc\u00e9d\u00e9 \u00e0 boues activ\u00e9es circulantes. Son fonctionnement consiste en trois \u00e9tapes : entr\u00e9e-a\u00e9ration-recirculation.<\/p>\n\n\n\n
3. M\u00e9thodes de traitement a\u00e9robie : Elles comprennent les processus de boues activ\u00e9es, les filtres biologiques et l'oxydation par contact.<\/p>\n\n\n\n
4. M\u00e9thode de traitement ana\u00e9robie-\u00e9robie : En fonction de la concentration et des caract\u00e9ristiques de traitement des polluants dans les diff\u00e9rentes eaux us\u00e9es, une combinaison appropri\u00e9e de processus ana\u00e9robies et a\u00e9robies est adopt\u00e9e. Au stade de l'hydrolyse ana\u00e9robie et de la production d'acide, les mati\u00e8res organiques r\u00e9calcitrantes peuvent \u00eatre d\u00e9compos\u00e9es en mati\u00e8res organiques \u00e0 mol\u00e9cules d'eau facilement d\u00e9gradables. La charge volum\u00e9trique \u00e9lev\u00e9e et la faible consommation d'\u00e9nergie du r\u00e9acteur ana\u00e9robie r\u00e9duisent consid\u00e9rablement la charge organique. Ensuite, les avantages du bior\u00e9acteur a\u00e9robie dans le traitement des eaux us\u00e9es organiques concentr\u00e9es sont utilis\u00e9s pour s'assurer que l'eau trait\u00e9e r\u00e9pond aux normes de rejet.<\/p>","protected":false},"excerpt":{"rendered":"
Currently, the most commonly used processes for treating dairy wastewater include biological contact oxidation, stand-alone aerobic treatment, anaerobic + aerobic treatment, and the SBR process and its improved versions. 1.
