Mvura yemarasha ndiyo mvura yemuswe weindasitiri inogadzirwa nekunyorova kwemarasha kugadzirira, iyo ine huwandu hukuru hwemarasha slime zvimedu uye ndiyo imwe yeakanyanya kusvibisa masosi emigodhi yemarasha. Mucus mvura yakaoma polydisperse system. Iyo inoumbwa nezvidimbu zvehukuru hwakasiyana, maumbirwo, densities uye lithofacies zvakasanganiswa muzvikamu zvakasiyana.
kwakabva:
Coal mine slurry water inogona kupatsanurwa muzvikamu zviviri: imwe inogadzirwa nekusuka marasha mambishi nezera diki re geological uye yakakwirira madota nekusachena zviri mukati; imwe yacho inogadzirwa panguva yekugezeswa nezera rakareba re geological uye zvirinani marasha ekugadzirwa kwemarasha.
chimiro:
Iyo mineral composition yemarasha slime yakaoma
Iyo particle size uye madota emukati emarasha slime ane simba guru pane flocculation uye sedimentation kuita.
Yakagadzikana muzvisikwa, yakaoma kubata
Inosanganisira nzvimbo dzakasiyana-siyana, inoda mari yakawanda, uye yakaoma kutarisira
kukuvadza:
Zvimedu zvakaturikwa mumvura yekugezesa marasha zvinosvibisa muviri wemvura uye zvinokanganisa kukura kwemhuka nemiti.
Marasha Kuwachisa Mvura Yakasviba Residue Chemical Pollution Environment
Kusvibiswa Kwezvakasara Kemikari Zvinhu muMarasha Ekugeza Mvura Yakasviba
Pamusana pekuoma uye kusiyana-siyana kweslime water system, nzira dzekurapa nemigumisiro yemvura yemvura yakasiyana. Nzira dzakajairwa dzekuchenesa mvura yeslime dzinonyanya zvinosanganisira nzira yekuisa sedimentation, gravity concentration sedimentation nzira uye coagulation sedimentation nzira.
Natural precipitation method
Munguva yakapfuura, marasha ekugadzira marasha ainyanya kuburitsa mvura ine slime yakananga mukati me slime sedimentation tangi yekunaya kwechisikigo, uye mvura yakajekeswa yaishandiswazve. Iyi nzira haidi kuwedzerwa kwemakemikari, kuderedza mari yekugadzira. Nekuvandudzwa kwesainzi uye tekinoroji uye nekuvandudzwa kwemigodhi yemarasha, zviri mukati memarasha akanaka akasarudzwa anowedzera, izvo zvinounza kuomerwa pakurapwa kwemvura yemarara. Zvinowanzotora mazuva kana mwedzi kuti nhamba huru yezvimedu zvakanaka zvigadzikane zvachose mumvura ine marara. Kazhinji kutaura, mvura yemarasha ine hukuru hukuru, kudzika kwakadzika, uye kuomarara kwakanyanya kuri nyore kunaya nemasikirwo, nepo zviri mukati mezvimedu zvakanaka uye zvicherwa zvevhu zvakakura, uye kunaya kwechisikigo kwakaoma.
kusangana kwesimba rinokwevera zvinhu pasi
Parizvino, zvidyarwa zvakawanda zvekugadzira marasha zvinoshandisa nzira yegiravhiti yekuisa sedimentation kurapa mvura ine slime, uye iyo gravity concentration sedimentation nzira inowanzoshandisa iyo thickener process. Yese mvura yetsvina inopinda mukati memukobvu kuti iomese, iwo mafashama anoshandiswa semvura inotenderera, uye iyo inoyerera inonatswa uye yobva yayangarara, uye mitsara inoyerera inogona kuburitswa kunze kwechirimwa kuti iraswe kana coagulation uye sedimentation kurapwa. Kana ichienzaniswa nekunaya kwechisikigo, iyo gravity concentration yekunaya nzira ine yakakura kugadzirisa kugona uye kugona kwakanyanya. Midziyo inowanzoshandiswa inosanganisira thickeners, filter presses, uye mafirita.
coagulation sedimentation nzira
Zvemukati metamorphic marasha akaderera munyika yangu zvakati wandei, uye mazhinji epasi metamorphic marasha akakwira madhaka mbishi marasha. Iyo inokonzeresa marasha slime ine yakakwira mvura yemukati uye zvimedu zvakanaka, zvichiita kuti zviome kugadzirisa. Coagulation inowanzo shandiswa mukugadzira marasha zvidyarwa kurapa mvura ine slime, kureva, nekuwedzera makemikari kuti agadzike uye aparadzanise yakaturikwa yakasimba mumvura ine slime muchimiro chezvimedu zvakakura kana zvakasununguka flocs, inova imwe yenzira huru yekujekesa zvakadzama. mvura yetsvina. . Iyo coagulation kurapwa neinorganic coagulants inonzi coagulation, uye iyo coagulation kurapwa nemapolymer komisheni inonzi flocculation. Iko kusanganiswa kushandiswa kwecoagulant uye flocculant kunogona kuvandudza mhedzisiro yemarasha slime kurapwa kwemvura. Zvinowanzoshandiswa zvinosanganisira inorganic flocculants, polymer flocculants, uye microbial flocculants.
