Les principales diff\u00e9rences entre le traitement de l'eau potable et le traitement des eaux us\u00e9es r\u00e9sident dans les cibles de traitement, les objectifs et les flux de processus :<\/p>\n\n\n\n
1. Diff\u00e9rences dans les objectifs de traitement<\/p>\n\n\n\n
Le traitement de l'eau potable cible les sources d'eau naturelles (telles que les eaux de surface et les eaux souterraines) et vise \u00e0 \u00e9liminer les mati\u00e8res en suspension, les micro-organismes et les substances nocives afin de garantir que la qualit\u00e9 de l'eau r\u00e9ponde aux normes en mati\u00e8re d'eau potable.<\/p>\n\n\n\n
L'\u00e9puration des eaux us\u00e9es traite les eaux us\u00e9es contamin\u00e9es (eaux us\u00e9es domestiques et industrielles), dans le but d'\u00e9liminer les polluants (tels que la DCO, la DBO et les MES) afin d'assurer la conformit\u00e9 avec les normes de rejet ou la r\u00e9utilisation.<\/p>\n\n\n\n
2. Diff\u00e9rences dans les objectifs de traitement<\/p>\n\n\n\n
Le traitement de l'eau potable doit r\u00e9pondre aux normes d'hygi\u00e8ne de l'eau potable domestique, telles que la turbidit\u00e9 \u2264 1 NTU, le chlore r\u00e9siduel 0,2-1,0 mg\/L et la num\u00e9ration bact\u00e9rienne totale \u2264 100 UFC\/mL.<\/p>\n\n\n\n
Le traitement des eaux us\u00e9es respecte les normes de rejet des polluants, telles que DBO5 \u2264 10 mg\/L, DCO \u2264 50 mg\/L et MES \u2264 10 mg\/L.<\/p>\n\n\n\n
3. Diff\u00e9rences dans le d\u00e9roulement du processus<\/p>\n\n\n\n
Traitement de l'eau potable : coagulation - s\u00e9dimentation - filtration - d\u00e9sinfection (chlore\/ozone\/lumi\u00e8re ultraviolette) - et \u00e9ventuellement traitement avanc\u00e9 suppl\u00e9mentaire (charbon actif\/traitement par membrane). Traitement des eaux us\u00e9es : D\u00e9grilleur - dessableur - d\u00e9canteur primaire - traitement biologique (boues activ\u00e9es\/biofilm) \u2192 d\u00e9canteur secondaire - d\u00e9sinfection.<\/p>\n\n\n\n
4. Diff\u00e9rences dans l'utilisation des effluents :<\/p>\n\n\n\n
Apr\u00e8s le traitement de l'eau potable, elle entre directement dans le r\u00e9seau municipal d'approvisionnement en eau.<\/p>\n\n\n\n
Les effluents du traitement des eaux us\u00e9es sont principalement utilis\u00e9s pour les rejets dans l'environnement, la r\u00e9utilisation industrielle ou l'utilisation de l'eau pour l'am\u00e9nagement paysager.<\/p>\n\n\n\n
5. Indicateurs et param\u00e8tres cl\u00e9s :<\/p>\n\n\n\n
Indicateurs cl\u00e9s de l'eau potable : turbidit\u00e9, chlore r\u00e9siduel, num\u00e9ration bact\u00e9rienne totale et bact\u00e9ries coliformes.<\/p>\n\n\n\n
Indicateurs cl\u00e9s des eaux us\u00e9es : DBO5, DCO, MES, phosphore total et ammoniac total.<\/p>","protected":false},"excerpt":{"rendered":"
The core differences between drinking water treatment and wastewater treatment lie in their treatment targets, objectives, and process flows: 1. Differences in Treatment Targets Drinking water treatment targets natural water sources (such as surface water and groundwater), aiming to remove suspended solids, microorganisms, and harmful substances to ensure water quality meets drinking water standards.
