Eaux usées de l'industrie du papier

Décharge standard, réutilisation de l'eau récupérée et rejet d'effluent nul

1. En ce qui concerne le traitement des eaux usées dans les usines de papier, les eaux usées en pâte sont les eaux usées les plus difficiles à traiter dans l'industrie du papier. Les polluants organiques et les sels inorganiques ont une teneur élevée, une composition complexe, une dureté élevée, des coûts élevés. Le staff technique deJIUWUTravailler avec des experts de l'Institut de la science et de la technologie des membranes de l'Université de Nanjing Tech et développer avec succès la technologie des membranes en tant que noyau du processus de rejet d'effluent nul ou zld (zéro décharge liquide).

2. L'utilisation du processus de prétraitement, d'intégration de membrane, de cristallisation par évaporation et d'autres processus connexes transforme les déchets en précieux et permet le recyclage des eaux usées. Le projet constitue une percée technologique majeure dans le domaine du traitement des eaux usées des pâtes et papiers.

Arrière-plan de l'application

Les prix de l'eau industrielle continuent d'augmenter
Limite de prise d'eau industrielle
Augmentation des normes de qualité de l'eau d'émission (COD, TOC, etc.)
Exigences d'application pour la protection de l'environnement et le taux de réutilisation de l'eau, etc.
Forte demande d'eau douce
Grande quantité de décharge d'eaux usées
La composition des eaux usées est complexe et la teneur en polluants organiques et en sels inorganiques est élevée.

Avantage de base du paquet de processus

Recherche et développement indépendant, Global First
Transformez les déchets en trésor et réalisez 100% réutilisation complète des eaux usées
Plusieurs projets de démonstration de 10,000 tonnes
Réutiliser l'eau, le sel et la boue sèche
La qualité de l'eau de l'eau produite est bonne et répond aux exigences de réutilisation productive.
Zld (zéro décharge liquide)

Cas

Jiangsu Jiuwu Hitech Co., Ltd a réalisé le plus grand projet de rejet de liquide zéro dans l'industrie de la pâte à papier. Le projet est situé au japonais Oji Paper Co., Ltd. (OJI PAPER) en Chine, à l'échelle de 40000m3/jour de fabrication du papier, eaux usées de pâte. Les principaux procédés comprennent le biofiltre couplé à l'ozone (élimination de la DCO), le système de membrane intégré deUf technoloGy et osmose inverse, système de concentration d'électrodialyse (EDR), système de cristallisation par évaporation MVR. Grâce au système de traitement avancé mentionné ci-dessus, la réalisation du recyclage des eaux usées et zéro rejet de liquide. L'eau propre est fournie au système de dessalement de la centrale électrique et au système d'eau de production, les déchets de sel sont fournis au Bureau des transports pour faire de l'agent de fonte des neiges et des matières premières chimiques. Le projet, qui est le plus grand projet de rejet zéro liquide au monde dans l'industrie de la pâte à papier, fonctionne de manière stable depuis plus de 3 ans.
