Mvura yemarasha inogadzirwa nemarasha imvura inobuda mumashure inogadzirwa nekugadzira marasha akanyorova, ine huwandu hwakawanda hwezvimedu zvemarasha uye ndeimwe yenzvimbo huru dzekusvibisa migodhi yemarasha. Mvura yemucus isystem yakaoma ye polydisperse. Inoumbwa nezvimedu zvehukuru hwakasiyana, maumbirwo, huwandu uye lithofacies zvakasanganiswa muhuwandu hwakasiyana.
manyuko:
Mvura inotsvedza yemugodhi wemarasha inogona kukamurwa kuita zvikamu zviviri: imwe inogadzirwa nekusuka marasha asina kucheneswa ane makore mapfupi enzvimbo uye dota rakawanda uye kusvibiswa; imwe inogadzirwa panguva yekusuka nezera renzvimbo uye marasha emhando yepamusoro ekugadzirwa kwemarasha asina kucheneswa.
chinhu:
Kuumbwa kwezvicherwa zvemarasha kwakaoma kunzwisisa
Saizi yezvidimbu uye huwandu hwedota riri mumarasha ane marasha zvine simba guru pakushanda kwe flocculation uye sedimentation.
Yakagadzikana muzvisikwa, yakaoma kubata
Inosanganisira nzvimbo dzakasiyana-siyana, inoda mari yakawanda, uye yakaoma kuitarisira
kukuvadza:
Zvinhu zvakasimba zvakasungirirwa mumvura yakasviba inosuka marasha zvinosvibisa mvura uye zvinokanganisa kukura kwemhuka nezvirimwa.
Kushambidza Marasha Kusvina Masara Emvura Yakasviba Kusvibiswa Kwemakemikari Nzvimbo
Kusvibiswa kweMakemikoro Akasara muMarasha Ekuwacha Mvura Yakasviba
Nekuda kwekuoma uye kusiyana kwehurongwa hwemvura yeslime, nzira dzekurapa uye mhedzisiro yemvura yeslime dzakasiyana. Nzira dzakajairika dzekurapa mvura yeslime dzinosanganisira nzira ye sedimentation yechisikigo, nzira ye gravity sedimentation uye nzira ye coagulation sedimentation.
nzira yekunaya kwemvura yechisikigo
Kare, mafekitori ekugadzira marasha ainyanya kuburitsa mvura yeslime zvakananga mutangi reslime sedimentation kuti mvura ipinde, uye mvura yakacheneswa yaidzokororwa. Nzira iyi haidi kuwedzerwa makemikari, zvichideredza mari yekugadzira. Nekuvandudzwa kwesainzi netekinoroji uye kuvandudzwa kwemichina yekuchera marasha, huwandu hwemarasha akanaka mumarasha asina kuchekwa hunowedzera, izvo zvinounza matambudziko pakurapa mvura yeslime. Kazhinji zvinotora mazuva kana mwedzi kuti huwandu hwakawanda hwezvinhu zvakanaka zvigare zvakakwana mumvura yeslime. Kazhinji, mvura yeslime yemarasha ine saizi huru, huwandu hushoma, uye kuomarara kwakanyanya kuri nyore kudonha zvakasikwa, nepo huwandu hwezvinhu zvakanaka uye zvicherwa zvevhu zvakakura, uye mvura yemusango yakaoma.
kuwanda kwegiravhiti
Parizvino, makambani mazhinji ekugadzira marasha anoshandisa nzira yegravity concentration sedimentation kurapa mvura yeslime, uye nzira yegravity concentration sedimentation inowanzo shandisa nzira ye thickener. Mvura yese yeslime inopinda mu thickener kuti irambe yakasimba, overflow inoshandiswa semvura inotenderera, uye underflow inoderedzwa yozobva yadonha, uye flotation tailings inogona kuburitswa kunze kweplant kuti iraswe kana kuvharika uye kugadziriswa kwesedimentation. Kana ichienzaniswa ne natural precipitation, nzira yegravity concentration precipitation ine kugona kukuru kwekugadzirisa uye inoshanda zvakanyanya. Midziyo inowanzoshandiswa inosanganisira thickeners, filter presses, uye filters.
nzira yekuvharira sedimentation
Huremu hwemarasha asina kuchinja hushoma munyika yangu hwakanyanya, uye marasha mazhinji asina kuchinja hushoma ane marasha asina kuchena akawanda. Marasha anobuda anobuda ane mvura yakawanda uye zvidimbu zvidiki, zvichiita kuti zviome kugadzikana. Kubatana kunowanzo shandiswa mumafekitori ekugadzirira marasha kurapa mvura ine slime, ndiko kuti, nekuwedzera makemikari kuti agadzikane uye kuparadzanisa zvinhu zvakasimba mumvura ine slime muchimiro chezvidimbu zvakakura kana zvidimbu zvakakurisa, inova imwe yenzira huru yekujekesa zvakadzama mvura ine slime. . Kubatana kwemarasha ne inorganic coagulants kunonzi coagulation, uye kusanganiswa kwe coagulation ne polymer compounds kunonzi flocculation. Kushandiswa pamwe chete kwe coagulant ne flocculant kunogona kuvandudza mhedzisiro yekurapa mvura ine slime yemarasha. Mishonga inowanzoshandiswa inosanganisira inorganic flocculants, polymer flocculants, uye microbial flocculants.
