Les m\u00e9thodes de traitement comprennent : le processus des boues activ\u00e9es, la technologie bio-am\u00e9lior\u00e9e, l'oxydation de l'eau supercritique, etc. Ces m\u00e9thodes visent \u00e0 r\u00e9duire la production d'eaux us\u00e9es \u00e0 la source, pour finalement atteindre z\u00e9ro, ce qui est connu sous le nom de technologie de r\u00e9duction des eaux us\u00e9es par cok\u00e9faction. Ces m\u00e9thodes visent \u00e0 r\u00e9duire la production d'eaux us\u00e9es \u00e0 la source, pour finalement l'annuler :<\/p>\n\n\n\n
1. Eau de s\u00e9paration du benz\u00e8ne brut :<\/p>\n\n\n\n
M\u00e9thode de traitement : distillation \u00e0 pression n\u00e9gative. Cette m\u00e9thode permet d'abaisser le point d'\u00e9bullition du benz\u00e8ne et d'\u00e9conomiser de la chaleur, mais elle utilise \u00e9galement de l'huile chaude en circulation pour le chauffage, ce qui r\u00e9duit la production d'eaux us\u00e9es.<\/p>\n\n\n\n
2. Eaux us\u00e9es d'extinction :<\/p>\n\n\n\n
M\u00e9thode de traitement : technologie de trempe \u00e0 sec. Un gaz inerte est utilis\u00e9 \u00e0 la place de l'eau pour refroidir le coke chauff\u00e9 \u00e0 blanc, ce qui permet de r\u00e9duire la consommation d'eau de 0,5 t\/tonne de coke.<\/p>\n\n\n\n
3. Eaux us\u00e9es de sulfate d'ammonium :<\/p>\n\n\n\n
M\u00e9thode de traitement : r\u00e9cup\u00e9ration et utilisation des condensats issus du processus de refroidissement final des gaz de cokerie. L'eau douce r\u00e9approvisionn\u00e9e dans le processus de sulfate d'ammonium existe finalement sous forme d'eau ammoniacale r\u00e9siduelle. L'utilisation du condensat provenant du processus de refroidissement final du gaz de cokerie pour remplacer la r\u00e9alimentation en eau douce \u00e0 l'ext\u00e9rieur du saturateur peut r\u00e9duire la charge de l'\u00e9limination de l'eau ammoniacale r\u00e9siduelle provenant du gaz de cokerie.<\/p>\n\n\n\n
4. Eaux us\u00e9es de strippage de l'hydrog\u00e8ne :<\/p>\n\n\n\n
M\u00e9thode de traitement : technologie de stripage de l'ammoniac \u00e0 l'huile de transfert de chaleur. En utilisant de l'huile de transfert de chaleur \u00e0 environ 270\u2103, une partie des eaux us\u00e9es rejet\u00e9es par la tour de stripage de l'ammoniac est chauff\u00e9e en vapeur pour le stripage de l'ammoniac, rempla\u00e7ant le stripage direct de l'ammoniac \u00e0 la vapeur et r\u00e9duisant la consommation d'eau de 0,3t\/tonne de coke.<\/p>","protected":false},"excerpt":{"rendered":"
Treatment methods include: activated sludge process, bio-enhanced technology, supercritical water oxidation, etc. These methods aim to reduce wastewater generation at its source, eventually reaching zero, which is known as coking wastewater reduction technology. Specifically: 1. Crude benzene separation water: Treatment method: negative pressure distillation. This lowers the boiling point of benzene, saving heat; however, it…<\/p>","protected":false},"author":1,"featured_media":2132,"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":[97,729,728],"class_list":["post-2237","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-categorized","category-waste-water-treatment-news","tag-activated-sludge-process","tag-quenching-wastewater","tag-reduce-wastewater-generation"],"_links":{"self":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2237","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=2237"}],"version-history":[{"count":1,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2237\/revisions"}],"predecessor-version":[{"id":2238,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2237\/revisions\/2238"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media\/2132"}],"wp:attachment":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media?parent=2237"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/categories?post=2237"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/tags?post=2237"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
