Amanzi e-slime yamalahle ngamanzi omsila wezimboni akhiqizwa ukulungiswa kwamalahle okumanzi, aqukethe inani elikhulu lezinhlayiya ze-slime yamalahle futhi angomunye wemithombo eyinhloko yokungcola kwezimayini zamalahle. Amanzi e-mucus ayisistimu eyinkimbinkimbi ye-polydisperse. Yakhiwa yizinhlayiya ezinobukhulu obuhlukene, izimo, ubuningi kanye nama-lithofacies axutshwe ngezilinganiso ezahlukene.
umthombo:
Amanzi odaka lwemayini yamalahle angahlukaniswa ngezigaba ezimbili: eyodwa ikhiqizwa ngokugeza amalahle angaphekiwe aneminyaka emifushane ye-geological kanye nokuqukethwe okuphezulu komlotha nokungcola; enye ikhiqizwa ngesikhathi senqubo yokuwasha eneminyaka emide ye-geological kanye namalahle asezingeni elingcono okukhiqizwa kwamalahle angaphekiwe.
isici:
Ukwakheka kwamaminerali kwe-slime yamalahle kuyinkimbinkimbi kakhulu
Usayizi wezinhlayiya kanye nokuqukethwe komlotha we-slime yamalahle kunethonya elikhulu ekusebenzeni kwe-flocculation kanye ne-sedimentation.
Izinzile ngokwemvelo, kunzima ukuyiphatha
Kuhilela izindawo eziningi ezahlukene, kudinga utshalomali olukhulu, futhi kunzima ukuphatha
ukulimala:
Izinto eziqinile ezilenga emanzini angcolile okugeza amalahle zingcolisa umzimba wamanzi futhi zithinta ukukhula kwezilwane nezitshalo
Ukugeza Amalahle Izinsalela Zamanzi Angcolile Indawo Yokungcola Kwamakhemikhali
Ukungcoliswa Kwezinto Ezisele Zamakhemikhali Emanzini Angcolile Okuhlanza Amalahle
Ngenxa yobunzima nokuhlukahluka kohlelo lwamanzi e-slime, izindlela zokwelapha kanye nemiphumela yamanzi e-slime zihlukile. Izindlela zokwelapha amanzi e-slime ezivamile zifaka phakathi indlela yemvelo yokuthungwa, indlela yokuthungwa kwe-gravity concentration kanye nendlela yokuthungwa kwe-coagulation sedimentation.
indlela yemvelo yokuna kwemvula
Esikhathini esidlule, izitshalo zokulungiselela amalahle zazikhipha amanzi e-slime ngqo ethangini le-slime sedimentation ukuze kube nemvula yemvelo, futhi amanzi acacisiwe aphinde asetshenziswe. Le ndlela ayidingi ukwengezwa kwamakhemikhali, okunciphisa izindleko zokukhiqiza. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthukiswa kwemishini yokumba amalahle, okuqukethwe kwamalahle amahle kumalahle aluhlaza akhethiwe kuyanda, okuletha ubunzima ekwelapheni amanzi e-slime. Ngokuvamile kuthatha izinsuku noma izinyanga ukuthi inani elikhulu lezinhlayiya ezinhle lihlale ngokuphelele emanzini e-slime. Ngokuvamile, amanzi e-slime amalahle anobukhulu obukhulu bezinhlayiya, ukuhlushwa okuphansi, kanye nobunzima obukhulu kulula ukuwakhipha ngokwemvelo, kuyilapho okuqukethwe kwezinhlayiya ezinhle namaminerali obumba kukhulu, kanti imvula yemvelo inzima.
ukuhlushwa kwamandla adonsela phansi
Njengamanje, izitshalo eziningi zokulungiselela amalahle zisebenzisa indlela yokudonsa amanzi adonsela phansi ukuze ziphathe amanzi e-slime, kanti indlela yokudonsa amanzi adonsela phansi ivame ukusebenzisa inqubo yokudonsa amanzi. Wonke amanzi e-slime angena ku-thickener ukuze agxile, ukugcwala kwamanzi kusetshenziswa njengamanzi ajikelezayo, bese ukugeleza kwamanzi kuyancishiswa bese kuba yi-flotation, bese ama-flotation tailings angakhishwa ngaphandle kwesitshalo ukuze alahlwe noma ajiyile futhi aphathwe nge-sedimentation. Uma kuqhathaniswa nemvula yemvelo, indlela yokudonsa amanzi adonsela phansi inamandla amakhulu okucubungula kanye nokusebenza kahle okuphezulu. Imishini evame ukusetshenziswa ifaka phakathi ama-thickeners, imishini yokuhlunga, kanye nezihlungi.
indlela yokujiya kwe-sedimentation
Okuqukethwe kwamalahle ashintshashintshayo ezweni lakithi kuphakeme kakhulu, futhi iningi lamalahle ashintshashintshayo aphansi ngamalahle aluhlaza anodaka oluningi. I-slime yamalahle ephumayo inokuqukethwe kwamanzi amaningi kanye nezinhlayiya ezincane, okwenza kube nzima ukuzinza. I-coagulation ivame ukusetshenziswa ezitshalweni zokulungiselela amalahle ukwelapha amanzi e-slime, okungukuthi, ngokungeza amakhemikhali ukuze ahlale futhi ahlukanise izinto eziqinile ezilengisiwe emanzini e-slime ngesimo sezinhlayiya ezinkulu noma ama-floc akhululekile, okungenye yezindlela eziyinhloko zokucacisa ngokujulile amanzi e-slime. . Ukwelashwa kwe-coagulation ngama-coagulants angaphili kubizwa ngokuthi i-coagulation, kanti ukwelashwa kwe-coagulation ngama-polymer compounds kubizwa ngokuthi i-flocculation. Ukusetshenziswa okuhlangene kwe-coagulant kanye ne-flocculant kungathuthukisa umphumela wokwelashwa kwamanzi e-slime yamalahle. Izinto ezisetshenziswa kakhulu zifaka phakathi ama-flocculants angaphili, ama-polymer flocculants, kanye nama-microbial flocculants.
