1. Laveur de tamis : utilis\u00e9 pour intercepter les grosses particules flottantes (telles que les d\u00e9chets de plastique et de papier) dans les eaux us\u00e9es, afin d'\u00e9viter le colmatage des \u00e9quipements ult\u00e9rieurs et d'assurer le fonctionnement normal du syst\u00e8me de traitement.<\/p>\n\n\n\n
2. Bac \u00e0 sable : Il \u00e9limine les graviers et les mati\u00e8res inorganiques des eaux us\u00e9es par s\u00e9paration gravitaire, r\u00e9duisant ainsi la charge sur le traitement ult\u00e9rieur. Les types les plus courants sont l'\u00e9coulement horizontal et l'a\u00e9ration.<\/p>\n\n\n\n
3. Dispositif d'a\u00e9ration : Il favorise la d\u00e9gradation de la mati\u00e8re organique par les micro-organismes pr\u00e9sents dans les eaux us\u00e9es, acc\u00e9l\u00e8re la croissance des boues activ\u00e9es gr\u00e2ce \u00e0 l'oxyg\u00e9nation et r\u00e9gule la concentration d'oxyg\u00e8ne dissous (g\u00e9n\u00e9ralement comprise entre 2 et 4 mg\/L).<\/p>\n\n\n\n
4. Clarificateur secondaire : R\u00e9alise la s\u00e9paration des boues et de l'eau et maintient la stabilit\u00e9 du syst\u00e8me de boues activ\u00e9es par le retour des boues. Le taux de retour est g\u00e9n\u00e9ralement de 30%-100%.<\/p>\n\n\n\n
5. D\u00e9shydrateur de boues : R\u00e9duit la teneur en humidit\u00e9 des boues \u00e0 un niveau inf\u00e9rieur \u00e0 80%. L'\u00e9quipement courant comprend des filtres-presses \u00e0 bande et des filtres-presses \u00e0 plaques et \u00e0 cadres pour faciliter l'\u00e9limination ult\u00e9rieure.<\/p>\n\n\n\n
6. Dispositif de d\u00e9sinfection : Il d\u00e9truit les agents pathog\u00e8nes pr\u00e9sents dans l'eau (tels que les bact\u00e9ries et les virus) afin de garantir que l'effluent satisfait aux normes de rejet. La d\u00e9sinfection au chlore, la d\u00e9sinfection \u00e0 l'ozone, etc. sont couramment utilis\u00e9es.<\/p>","protected":false},"excerpt":{"rendered":"
1. Screen Scrubber: Used to intercept large floating particles (such as plastic and paper scraps) in sewage, preventing clogging of subsequent equipment and ensuring the normal operation of the treatment system. 2. Grit Chamber: Removes grit and inorganic matter from sewage through gravity separation, reducing the load on subsequent treatment. Common types include horizontal flow…<\/p>","protected":false},"author":1,"featured_media":2123,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"footnotes":""},"categories":[1,32],"tags":[615,614,613,616,617],"class_list":["post-2148","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-categorized","category-waste-water-treatment-news","tag-aeration-device","tag-grit-chamber","tag-screen-scrubber","tag-secondary-clarifier","tag-sludge-dewaterer"],"_links":{"self":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2148","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/comments?post=2148"}],"version-history":[{"count":1,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2148\/revisions"}],"predecessor-version":[{"id":2149,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2148\/revisions\/2149"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media\/2123"}],"wp:attachment":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media?parent=2148"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/categories?post=2148"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/tags?post=2148"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
