Amanzi e-slime wamalahle amanzi omsila wezimboni akhiqizwa ukulungiswa kwamalahle okumanzi, aqukethe izinhlayiya eziningi ze-slime yamalahle futhi ingenye yemithombo eyinhloko yokungcoliswa kwezimayini zamalahle. Amanzi ama-mucus uhlelo oluyinkimbinkimbi lwe-polydisperse. Yakhiwa izinhlayiya ezinobukhulu obuhlukahlukene, ubujamo, ukuminyana kanye nama-lithofacies axutshwe ngezilinganiso ezahlukene.
umthombo:
Amanzi anodaka emayini yamalahle angahlukaniswa abe izigaba ezimbili: eyodwa ikhiqizwa ngokugeza amalahle aluhlaza anesikhathi esifushane sokwakheka komhlaba kanye nomlotha omningi nokungcola; enye ikhiqizwa ngesikhathi sokuwashwa ngeminyaka ende ye-geological kanye nekhwalithi engcono yamalahle okukhiqizwa kwamalahle aluhlaza.
isici:
Ukwakheka kwamaminerali kwe-slime yamalahle kuyinkimbinkimbi
Usayizi wezinhlayiya kanye nokuqukethwe komlotha we-slime yamalahle kunethonya elikhulu ekusebenzeni kwe-flocculation nokusebenza kwe-sedimentation.
Izinzile ngokwemvelo, kunzima ukuphatha
Kubandakanya izinhlobonhlobo zezindawo, kudinga ukutshalwa kwezimali okukhulu, futhi kunzima ukukuphatha
umonakalo:
Izinto eziqinile ezilengisiwe emanzini angcolile okugeza amalahle zingcolisa umzimba wamanzi futhi zibe nomthelela ekukhuleni kwezilwane nezitshalo
Ukuwashwa Kwamalahle Kwezinsalela Zamanzi Angcolile Imvelo Yokungcoliswa Kwemvelo
Ukungcoliswa Kwezinto Zamakhemikhali Ezinsalela Emanzini Angcolile Okuwashwa Amalahle
Ngenxa yobunzima kanye nokuhlukahluka kwesistimu yamanzi e-slime, izindlela zokwelashwa kanye nemiphumela yamanzi e-slime zihlukile. Izindlela ezijwayelekile zokwelapha amanzi e-slime ikakhulukazi zifaka indlela yemvelo ye-sedimentation, indlela ye-gravity concentration sedimentation kanye nendlela ye-coagulation sedimentation.
indlela yemvelo yemvula
Esikhathini esedlule, izitshalo zokulungisa amalahle zazikhipha amanzi e-slime ngqo ethangini le-slime sedimentation ukuze kunemvula yemvelo, futhi amanzi acacisiwe ayephinde asetshenziswe. Le ndlela ayidingi ukungezwa kwamakhemikhali, ukunciphisa izindleko zokukhiqiza. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokwenza ngcono kwemishini yezimayini zamalahle, okuqukethwe kwamalahle acolekileyo endaweni ekhethiwe kuyakhula, okuletha ubunzima ekwelashweni kwamanzi e-slime. Ngokuvamile kuthatha izinsuku noma ngisho izinyanga ukuthi inqwaba yezinhlayiya ezinhle zihlale ngokuphelele emanzini e-slime. Ngokuvamile, amanzi e-slime wamalahle anosayizi omkhulu wezinhlayiyana, ukugxila okuphansi, nobulukhuni obuphezulu kulula ukudlidliza ngokwemvelo, kuyilapho okuqukethwe kwezinhlayiya ezinhle namaminerali obumba kukhulu, futhi imvula yemvelo inzima.
ukugxila kwamandla adonsela phansi
Njengamanje, izitshalo eziningi zokulungiselela amalahle zisebenzisa indlela yokugxilisa amandla adonsela phansi ukwelapha amanzi e-slime, futhi indlela yokugxilisa amandla adonsela phansi ngokuvamile isebenzisa inqubo yokuqina. Wonke amanzi e-slime angena ku-thickener ukuze agxilise, ukuchichima kusetshenziswa njengamanzi ajikelezayo, futhi ukugeleza okungaphansi kuyahlanjululwa bese ku-flotation, futhi ama-tailings e-flotation angakhishwa ngaphandle kwesitshalo ukuze alahlwe noma ahlanganiswe nokwelashwa kwe-sedimentation. Uma kuqhathaniswa nemvula yemvelo, indlela yokumisa ukugxilisa amandla adonsela phansi inomthamo omkhulu wokucubungula nokusebenza kahle okuphezulu. Imishini esetshenziswa kakhulu ihlanganisa ama-thickeners, izihlungi, nezihlungi.
indlela ye-coagulation sedimentation
Okuqukethwe kwamalahle e-metamorphic aphansi ezweni lami kuphezulu uma kuqhathaniswa, futhi iningi lamalahle e-metamorphic aphansi amalahle anodaka oluphezulu. I-slime yamalahle ewumphumela inokuqukethwe okuphezulu kwamanzi kanye nezinhlayiya ezinhle, okwenza kube nzima ukuzinza. I-coagulation ivame ukusetshenziswa ezitshalweni zokulungiselela amalahle ukwelapha amanzi e-slime, okungukuthi, ngokungeza amakhemikhali ukuze axazulule futhi ahlukanise izinto eziqinile ezimisiwe emanzini e-slime ngendlela yezinhlayiya ezinkulu noma ama-flocs avulekile, okungenye yezindlela eziyinhloko zokucacisa ngokujulile amanzi e-slime. . Ukwelashwa kwe-coagulation ngama-coagulants we-inorganic kubizwa ngokuthi i-coagulation, futhi ukwelashwa kokuhlanganisa ngezinhlanganisela ze-polymer kubizwa ngokuthi i-flocculation. Ukusetshenziswa okuhlangene kwe-coagulant kanye ne-flocculant kungathuthukisa umphumela wokwelashwa kwamanzi e-slime yamalahle. Ama-ejenti asetshenziswa kakhulu afaka ama-inorganic flocculants, ama-polymer flocculants, nama-microbial flocculants.
