Il est n\u00e9cessaire de s\u00e9lectionner une combinaison appropri\u00e9e de technologies en fonction des caract\u00e9ristiques de la qualit\u00e9 de l'eau. Les m\u00e9thodes suivantes sont courantes et efficaces :<\/p>\n\n\n\n
1. M\u00e9thode d'oxydation chimique<\/p>\n\n\n\n
1.1 Oxydation de Fenton : Utilise la r\u00e9action du Fe\u00b2\u207a avec H\u2082O\u2082 pour g\u00e9n\u00e9rer des radicaux hydroxyles (-OH), qui peuvent d\u00e9grader efficacement les mati\u00e8res organiques r\u00e9fractaires (telles que les eaux us\u00e9es chimiques et pharmaceutiques).<\/p>\n\n\n\n
1.2 Oxydation \u00e0 l'ozone : Am\u00e9lioration de l'efficacit\u00e9 gr\u00e2ce aux mol\u00e9cules d'ozone ou au couplage UV\/H\u2082O\u2082, convient aux eaux us\u00e9es organiques \u00e0 forte concentration, mais le co\u00fbt de l'\u00e9quipement est relativement \u00e9lev\u00e9.<\/p>\n\n\n\n
2. Technologie de traitement biologique<\/p>\n\n\n\n
2.1 Processus combin\u00e9 ana\u00e9robie-a\u00e9robie (tel que UASB + MBR) : La section ana\u00e9robie d\u00e9grade la DCO mol\u00e9culaire de grande taille et la section a\u00e9robie \u00e9limine les polluants r\u00e9siduels.<\/p>\n\n\n\n
2.2 Adsorption sur charbon actif : Il a un taux d'\u00e9limination \u00e9lev\u00e9 pour la DCO \u00e0 faible concentration (<100 mg\/L) et peut \u00eatre recycl\u00e9 ; le charbon actif charg\u00e9 en m\u00e9taux peut catalyser l'oxydation de mani\u00e8re synergique.<\/p>\n\n\n\n
3. Technologie de s\u00e9paration physique<\/p>\n\n\n\n
3.1 S\u00e9paration membranaire (ultrafiltration + osmose inverse) : filtration et dessalement en profondeur, adapt\u00e9s aux besoins de r\u00e9utilisation des eaux us\u00e9es de l'industrie \u00e9lectronique ; la technologie des membranes dynamiques est moins co\u00fbteuse.<\/p>\n\n\n\n
4. Processus combin\u00e9<\/p>\n\n\n\n
4.1 DCO \u00e0 forte concentration (lixiviat de d\u00e9charge, par exemple) : acidification ana\u00e9robie \u2192 nitrification raccourcie - oxydation ana\u00e9robie de l'ammonium \u2192 oxydation Fenton \u2192 adsorption sur charbon actif.<\/p>","protected":false},"excerpt":{"rendered":"
