Le traitement des eaux us\u00e9es des verreries adopte principalement un processus combin\u00e9 de \u201cpr\u00e9traitement + traitement principal + traitement avanc\u00e9 + r\u00e9utilisation\u201d pour parvenir \u00e0 un rejet conforme ou \u00e0 une r\u00e9utilisation des ressources, comme indiqu\u00e9 ci-dessous :<\/p>\n\n\n\n
1. Pr\u00e9traitement<\/p>\n\n\n\n
1.1 D\u00e9grilleur\/criblage : \u00c9limine les grosses particules d'impuret\u00e9s<\/p>\n\n\n\n
1.2 R\u00e9servoir d'\u00e9galisation : \u00c9quilibre la qualit\u00e9 et la quantit\u00e9 de l'eau<\/p>\n\n\n\n
1.3 R\u00e9servoir de s\u00e9dimentation : \u00c9limine dans un premier temps les solides en suspension<\/p>\n\n\n\n
1.4 S\u00e9parateur d'huile (en cas d'eaux us\u00e9es huileuses) : S\u00e9pare les substances huileuses<\/p>\n\n\n\n
2. Traitement principal<\/p>\n\n\n\n
2.1 Coagulation et s\u00e9dimentation : Ajout de chlorure de polyaluminium (PAC) et de polyacrylamide (PAM) pour \u00e9liminer les solides en suspension et les collo\u00efdes.<\/p>\n\n\n\n
2.2 Pr\u00e9cipitation chimique :<\/p>\n\n\n\n
2.3 D\u00e9fluoruration : Ajout de lait de chaux pour g\u00e9n\u00e9rer un pr\u00e9cipit\u00e9 de fluorure de calcium (CaF\u2082).<\/p>\n\n\n\n
2.4 \u00c9limination des m\u00e9taux lourds : Ajustement du pH pour pr\u00e9cipiter les hydroxydes de m\u00e9taux lourds ou ajout d'agents ch\u00e9lateurs.<\/p>\n\n\n\n
2.5 Flottation \u00e0 l'air (adapt\u00e9e aux mati\u00e8res huileuses et aux solides fins en suspension) : Am\u00e9liore l'efficacit\u00e9 de l'\u00e9limination<\/p>\n\n\n\n
3. Traitement avanc\u00e9<\/p>\n\n\n\n
3.1 Traitement biologique : Si la mati\u00e8re organique est \u00e9lev\u00e9e (DCO > 500 mg\/L), hydrolyse acidification + 3.1 Oxydation par contact ou bior\u00e9acteur \u00e0 membrane MBR<\/p>\n\n\n\n
3.2 Oxydation avanc\u00e9e (par exemple, ozone, Fenton) : D\u00e9gradation de la mati\u00e8re organique r\u00e9calcitrante<\/p>\n\n\n\n
3.3 S\u00e9paration membranaire : L'ultrafiltration (UF) + l'osmose inverse (RO) garantissent le respect des normes de r\u00e9utilisation des effluents.<\/p>\n\n\n\n
4. R\u00e9utilisation et r\u00e9cup\u00e9ration des ressources<\/p>\n\n\n\n
4.1 Les effluents peuvent \u00eatre utilis\u00e9s pour le nettoyage des mati\u00e8res premi\u00e8res, la r\u00e9alimentation en eau de refroidissement, etc., avec un taux de r\u00e9utilisation de 80%-90%.<\/p>\n\n\n\n
4.2 Apr\u00e8s d\u00e9shydratation, les boues sont \u00e9limin\u00e9es dans une d\u00e9charge s\u00fbre ou utilis\u00e9es pour la r\u00e9cup\u00e9ration des ressources, en fonction de leur composition.<\/p>","protected":false},"excerpt":{"rendered":"
