Les eaux us\u00e9es domestiques comprennent principalement les eaux us\u00e9es produites par les m\u00e9nages, les entreprises et les installations urbaines, et contiennent les \u00e9l\u00e9ments suivants :<\/p>\n\n\n\n
1) Polluants organiques<\/p>\n\n\n\n
Il s'agit notamment des prot\u00e9ines, des graisses, des hydrates de carbone (tels que la cellulose, l'amidon et les sucres) et de l'ur\u00e9e, qui sont susceptibles de produire des odeurs naus\u00e9abondes dans des conditions ana\u00e9robies.<\/p>\n\n\n\n
2) Polluants inorganiques<\/p>\n\n\n\n
Il s'agit d'\u00e9l\u00e9ments tels que l'azote, le phosphore et le soufre (tels que les chlorures, les sulfates et les phosphates), ainsi que de min\u00e9raux tels que le calcium et le magn\u00e9sium.<\/p>\n\n\n\n
3) Micro-organismes pathog\u00e8nes<\/p>\n\n\n\n
Il s'agit notamment de bact\u00e9ries, de virus et d'\u0153ufs de parasites, qui peuvent propager des maladies.<\/p>\n\n\n\n
4) Mati\u00e8res en suspension et s\u00e9diments<\/p>\n\n\n\n
Environ 40% de polluants existent sous forme de mati\u00e8res insolubles, y compris le limon et les fibres, dont certaines se d\u00e9posent au fond de l'eau ou restent en suspension dans l'eau.<\/p>\n\n\n\n
5) R\u00e9sidus de d\u00e9tergents<\/p>\n\n\n\n
Les d\u00e9tergents contenant du phosphore peuvent entra\u00eener des niveaux excessifs de phosphore dans les masses d'eau, augmentant ainsi le risque d'eutrophisation.<\/p>","protected":false},"excerpt":{"rendered":"
Domestic sewage primarily consists of wastewater generated by households, businesses, and urban facilities, and contains the following components: 1) Organic pollutants These include proteins, fats, carbohydrates (such as cellulose, starch, and sugars), and urea, which are prone to producing foul odors under anaerobic conditions. 2) Inorganic pollutants These include elements such as nitrogen, phosphorus, and…<\/p>","protected":false},"author":1,"featured_media":2028,"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,"_kad_post_classname":"","footnotes":""},"categories":[1,32],"tags":[512,527],"class_list":["post-2106","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-categorized","category-waste-water-treatment-news","tag-domestic-sewage","tag-primarily-consists"],"_links":{"self":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2106","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=2106"}],"version-history":[{"count":1,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2106\/revisions"}],"predecessor-version":[{"id":2107,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2106\/revisions\/2107"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media\/2028"}],"wp:attachment":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media?parent=2106"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/categories?post=2106"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/tags?post=2106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
