1. Elle pr\u00e9sente une forte concentration de mati\u00e8res organiques, beaucoup de solides en suspension et une couleur fonc\u00e9e. Elle contient une grande quantit\u00e9 d'excr\u00e9ments d'animaux, ce qui entra\u00eene une tr\u00e8s forte concentration de NH3-N, ainsi qu'un grand nombre de bact\u00e9ries pathog\u00e8nes.<\/p>\n\n\n\n
2. Les polluants pr\u00e9sents dans les eaux us\u00e9es existent principalement sous la forme d'hydrates de carbone solides et dissous, ce qui fait que les eaux us\u00e9es pr\u00e9sentent des niveaux \u00e9lev\u00e9s de DBO5, de DCOcr, de MES et de couleur. En m\u00eame temps, les eaux us\u00e9es ont une bonne biod\u00e9gradabilit\u00e9 et contiennent une grande quantit\u00e9 de nutriments tels que l'azote et le phosphore.<\/p>\n\n\n\n
3. Le r\u00e9sidu solide dans les eaux us\u00e9es est principalement constitu\u00e9 de mati\u00e8re organique, ce qui n\u00e9cessite un pr\u00e9traitement intensif et une s\u00e9paration solide-liquide afin de r\u00e9duire la charge sur les processus de traitement ult\u00e9rieurs.<\/p>\n\n\n\n
4. Les eaux us\u00e9es de l'aquaculture pr\u00e9sentent les \"trois hauts\" typiques : forte concentration de mati\u00e8res organiques (DCO pouvant atteindre 3 000 \u00e0 12 000 mg\/l), forte concentration d'azote ammoniacal (800 \u00e0 2 200 mg\/l), forte teneur en mati\u00e8res en suspension (MES d\u00e9passant les normes de plusieurs dizaines de fois), couleur intense et niveaux \u00e9lev\u00e9s de bact\u00e9ries, d'azote ammoniacal et de phosphore organique.<\/p>","protected":false},"excerpt":{"rendered":"
