Kuchiza madzi a malasha

Madzi amatope a malasha ndi madzi a mchira wa mafakitale omwe amapangidwa ndi kukonzekera kwa malasha konyowa, komwe kumakhala ndi tinthu tambiri ta malasha ndipo ndi imodzi mwazinthu zomwe zimaipitsa migodi ya malasha. Madzi a ntchofu ndi njira yovuta ya polydisperse. Zimapangidwa ndi tinthu tating'onoting'ono tosiyanasiyana, mawonekedwe, makulidwe ndi lithofacies wosakanikirana mosiyanasiyana.

gwero:

Madzi a matope a malasha akhoza kugawidwa m'magulu awiri: imodzi imapangidwa ndi kutsuka malasha aiwisi ndi zaka zazifupi za geological ndi phulusa lapamwamba ndi zonyansa; ina imapangidwa panthawi yotsuka ndi nthawi yayitali ya geological ndi malasha abwino kwambiri opangira malasha aiwisi.

mawonekedwe:

Mapangidwe a mchere wa malasha ndi ovuta

Kukula kwa tinthu tating'ono ndi phulusa la matope a malasha kumakhudza kwambiri magwiridwe antchito a flocculation ndi sedimentation.

Wokhazikika mwachilengedwe, wovuta kunyamula

Zimaphatikizapo madera osiyanasiyana, zimafuna ndalama zambiri, ndipo zimakhala zovuta kuziyendetsa

kuvulaza:

Zolimba zotayidwa m'madzi ochapira malasha zimawononga madzi komanso zimakhudza kukula kwa nyama ndi zomera.

Kutsuka Malasha Madzi Otayira Otsalira Chemical Pollution Environment

Kuipitsa Zinthu Zotsalira M'madzi Ochapira Malasha

Chifukwa cha zovuta komanso kusiyanasiyana kwa madzi a matope, njira zochiritsira ndi zotsatira za madzi a matope ndizosiyana. Njira zodziwika bwino zochizira madzi amatope makamaka zimaphatikizira njira yachilengedwe ya sedimentation, gravity concentration sedimentation njira ndi coagulation sedimentation.

njira yachilengedwe yamvula

M'mbuyomu, malo opangira malasha nthawi zambiri amathira madzi amatope mwachindunji mu thanki ya matope kuti kukhale mvula yachilengedwe, ndipo madzi oyeretsedwawo amawagwiritsanso ntchito. Njirayi sikutanthauza kuwonjezera kwa mankhwala, kuchepetsa ndalama zopangira. Ndi chitukuko cha sayansi ndi luso lamakono komanso kusintha kwa makina a migodi ya malasha, zomwe zili mu malasha osankhidwa bwino zimawonjezeka, zomwe zimabweretsa zovuta pokonza madzi a matope. Nthawi zambiri zimatenga masiku kapena miyezi kuti tinthu tambirimbiri tikhazikike m'madzi amatope. Nthawi zambiri, madzi amatope a malasha okhala ndi kukula kwakukulu kwa tinthu, ndende yotsika, komanso kuuma kwakukulu ndikosavuta kugwa mwachilengedwe, pomwe zomwe zili ndi tinthu tating'onoting'ono ndi mchere wadongo ndizambiri, ndipo kugwa kwachilengedwe kumakhala kovuta.

ndende ya mphamvu yokoka

Pakalipano, zomera zambiri zokonzekera malasha zimagwiritsa ntchito njira yokoka ya matope kuti zithetse madzi amatope, ndipo njira yochepetsera mphamvu yokoka nthawi zambiri imagwiritsa ntchito njira ya thickener. Madzi onse amatope amalowa mu thickener kuti akhazikike, kusefukira kwake kumagwiritsidwa ntchito ngati madzi ozungulira, ndipo pansi pake amachepetsedwa ndiyeno kuyandama, ndipo ma tailings oyandama amatha kutulutsidwa kunja kwa chomera kuti atayike kapena kusungunuka ndi kusungunuka. Poyerekeza ndi mvula zachilengedwe, mphamvu yokoka ndende mpweya njira ali lalikulu processing mphamvu ndi mkulu dzuwa. Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi zonenepa, zosindikizira zosefera, ndi zosefera.

njira ya coagulation sedimentation

Malasha otsika kwambiri m'dziko langa ndi okwera kwambiri, ndipo ambiri mwa malasha otsika kwambiri ndi malasha amatope ambiri. Chotsatira cha malasha chimakhala ndi madzi ambiri komanso tinthu tating'onoting'ono, zomwe zimapangitsa kuti zikhale zovuta kukhazikika. Coagulation nthawi zambiri amagwiritsidwa ntchito m'mafakitale opangira malasha kuti athetse madzi amatope, ndiye kuti, powonjezera mankhwala kuti akhazikitse ndikulekanitsa zolimba zolimba m'madzi amatope ngati tinthu tating'onoting'ono kapena tinthu tating'onoting'ono totayirira, yomwe ndi imodzi mwazinthu zazikulu zofotokozera zakuya. madzi amatope. . Chithandizo cha coagulation ndi ma inorganic coagulants amatchedwa coagulation, ndipo chithandizo cha coagulation ndi mankhwala a polima amatchedwa flocculation. The ophatikizana ntchito coagulant ndi flocculant akhoza kusintha zotsatira za malasha matope madzi mankhwala. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo ma inorganic flocculants, ma polymer flocculants, ndi ma microbial flocculants.
