Ka mālama ʻana i ka wai palapū lanahu

ʻO ka wai palaki lanahu ka wai huelo ʻoihana i hana ʻia e ka hoʻomākaukau ʻana i ka lanahu pulu, nona ka nui o nā ʻāpana palaki lanahu a ʻo ia kekahi o nā kumu haumia nui o nā lua lanahu. He ʻōnaehana polydisperse paʻakikī ka wai Mucus. Hana ʻia ia me nā ʻāpana o nā nui like ʻole, nā ʻano, nā densities a me nā lithofacies i hui pū ʻia i nā ʻāpana like ʻole.

kumu:

Hiki ke hoʻokaʻawale ʻia ka wai slurry o ka mine lanahu i ʻelua mau ʻāpana: hana ʻia kekahi ma ka holoi ʻana i ka lanahu maka me kahi makahiki geological pōkole a me ka lehu kiʻekiʻe a me ka haumia; hana ʻia kekahi i ka wā holoi me kahi makahiki geological lōʻihi a me ka lanahu maikaʻi o ka hana lanahu maka.

hiʻohiʻona:

He paʻakikī ka hoʻohuihui mineral o ka slime lanahu

He mana koʻikoʻi ka nui o ka ʻāpana a me ka nui o ka lehu o ka slime lanahu i ka hana flocculation a me ka sedimentation

Paʻa ke ʻano, paʻakikī ke lawelawe

He ākea nā wahi e pili ana, koi i kahi hoʻopukapuka kālā nui, a he paʻakikī ke hoʻokele

pōʻino:

Hoʻohaumia nā mea paʻa i hoʻoheheʻe ʻia i loko o ka wai hoʻomaʻemaʻe lanahu i ke kino wai a hoʻopilikia i ka ulu ʻana o nā holoholona a me nā mea kanu.

Ka holoi ʻana i ka lanahu, ke koena o ka wai ʻino, ka haumia kemika, ke kaiapuni

Ka haumia o nā mea kemika koena i loko o ka wai holoi lanahu

Ma muli o ka paʻakikī a me ke ʻano like ʻole o ka ʻōnaehana wai slime, ʻokoʻa nā ʻano hana a me nā hopena o ka wai slime. ʻO nā ʻano hana mālama wai slime maʻamau e komo pū me ke ʻano sedimentation kūlohelohe, ke ʻano sedimentation concentration gravity a me ke ʻano sedimentation coagulation.

ke ʻano hoʻohā kūlohelohe

I ka wā ma mua, ua hoʻokuʻu pinepine nā hale hana hoʻomākaukau lanahu i ka wai slime i loko o ka pahu sedimentation slime no ka ua kūlohelohe, a ua hana hou ʻia ka wai i hoʻomaʻemaʻe ʻia. ʻAʻole koi kēia ʻano hana i ka hoʻohui ʻana i nā kemika, e hōʻemi ana i nā kumukūʻai hana. Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana a me ka hoʻomaikaʻi ʻana o ka mīkini ʻeli lanahu, piʻi ka nui o ka lanahu maikaʻi i loko o ka lanahu maka i koho ʻia, kahi e lawe mai ai i nā pilikia i ka mālama ʻana i ka wai slime. He mau lā a he mau mahina paha no ka nui o nā ʻāpana maikaʻi e noho piha i loko o ka wai slime. Ma ke ʻano laulā, ʻo ka wai slime lanahu me ka nui o nā ʻāpana, ka haʻahaʻa o ka noʻonoʻo, a me ka paʻakikī kiʻekiʻe e maʻalahi ke hoʻoheheʻe maoli ʻia, ʻoiai he nui ka nui o nā ʻāpana maikaʻi a me nā minelala lepo, a he paʻakikī ka ua kūlohelohe.

ka nui o ke kaumaha

I kēia manawa, hoʻohana ka hapa nui o nā hale hana hoʻomākaukau lanahu i ke ʻano sedimentation concentration gravity e mālama ai i ka wai slime, a hoʻohana pinepine ke ʻano sedimentation concentration gravity i ke kaʻina hana thickener. Komo nā wai slime āpau i loko o ka thickener e hoʻopili, hoʻohana ʻia ka overflow e like me ka wai e kaʻapuni ana, a hoʻoheheʻe ʻia ke kahe ma lalo a laila flotation, a hiki ke hoʻokuʻu ʻia nā tailings flotation ma waho o ka hale hana no ka hoʻolei ʻana a i ʻole ka coagulation a me ka mālama sedimentation. Ke hoʻohālikelike ʻia me ka ua kūlohelohe, loaʻa i ke ʻano precipitation concentration ka mana hana nui a me ka pono kiʻekiʻe. ʻO nā lako hana maʻamau e komo pū me nā thickeners, nā mīkini kaomi kānana, a me nā kānana.

ke ʻano hoʻoheheʻe coagulation

ʻOi aku ka kiʻekiʻe o ka nui o ka lanahu metamorphic haʻahaʻa ma koʻu ʻāina, a ʻo ka hapa nui o ka lanahu metamorphic haʻahaʻa he lanahu maka lepo kiʻekiʻe. ʻO ka slime lanahu hopena he nui ka wai a me nā ʻāpana liʻiliʻi, e paʻakikī ai ke noho. Hoʻohana pinepine ʻia ka coagulation i nā hale hana hoʻomākaukau lanahu e mālama i ka wai slime, ʻo ia hoʻi, ma ka hoʻohui ʻana i nā kemika e noho a hoʻokaʻawale i nā mea paʻa i hoʻokuʻu ʻia i loko o ka wai slime ma ke ʻano o nā ʻāpana nui a i ʻole nā ​​​​flocs wehe, ʻo ia kekahi o nā ala nui o ka hoʻomālamalama hohonu ʻana o ka wai slime. . ʻO ka mālama ʻana i ka coagulation me nā coagulants inorganic ua kapa ʻia ʻo coagulation, a ʻo ka mālama ʻana i ka coagulation me nā hui polymer ua kapa ʻia ʻo flocculation. ʻO ka hoʻohana pū ʻana o ka coagulant a me ka flocculant hiki ke hoʻomaikaʻi i ka hopena o ka mālama ʻana i ka wai slime lanahu. ʻO nā mea hana i hoʻohana pinepine ʻia e komo pū me nā flocculants inorganic, nā flocculants polymer, a me nā flocculants microbial.
