Nzira yekuparadzanisa mafuta-mvura:
1. Sefa nzira
Iyo nzira yekusefa ndeyekupfuudza mvura yakaraswa kuburikidza nemudziyo une maperforations kana kuburikidza nesefa layer inoumbwa neimwe granular medium, uye kushandisa kupindira kwayo, kuongorora, kudhumhana kweinertial uye mamwe mabasa ekubvisa zvakamiswa solids nemafuta mumvura ine tsvina uye. zvimwe zvinhu zvinokuvadza.
2. Gravity kupatsanura nzira
Kupatsanurwa kwegiravhiti ndiyo yakajairika nzira yekurapa, iyo inoshandisa density mutsauko pakati pemafuta nemvura uye kusapindirana kwemafuta nemvura kuparadzanisa madonhwe emafuta, zvakamiswa zvakaomeswa uye mvura mune inomira kana kuyerera.Madonhwe emafuta anoparadzirwa mumvura zvishoma nezvishoma anoyangarara uye akaturikidzana pasi pechiito chebuoyancy.Kumhanya kunoyangarara kwemadonhwe emafuta kunoenderana nehukuru hwemadonhwe emafuta, mutsauko wehutsi pakati peoiri nemvura, mamiriro ekuyerera uye viscosity yemvura.Hukama huri pakati pavo hunogona kutsanangurwa nemitemo yakaita saStokes naNewton.
3. Centrifugal separation
Centrifugal separation method ndeyekutenderedza chigaba chine mafuta tsvina ine mafuta nekumhanya kukuru kuita centrifugal force field.Nekuda kwekusiyana kwakasiyana kwezvimedu zvakasimba, madonhwe emafuta uye tsvina yemvura, simba recentrifugal rinogamuchirwa rakasiyanawo, kuitira kuti ribvise zvimedu zvakasimba uye madonhwe emafuta kubva mumvura yakasviba.
4. Flotation nzira
Flotation nzira, inozivikanwawo semhepo flotation nzira, ndiyo tekinoroji yekurapa mvura iri kuongororwa uye kusimudzirwa nguva dzose kumba nekune dzimwe nyika.Iyo nzira ndeyekupinza mhepo kana imwe gasi mumvura kuti ibudise mabhuru emhepo akanaka, kuitira kuti mamwe madonhwe emafuta akarembera akarembera uye zvimedu zvakasimba zviri mumvura zvinonamirwa kumabhuru emhepo, uye zvinoyangarara pamusoro pemvura pamwe chete nemabhuru emhepo. gadzira scum (ine mafuta-ine furo layer), wobva washandisa yakakodzera Iyo mafuta skimmer inonyudza mafuta.
5. Biological oxidation nzira
Biological oxidation inzira yekuchenesa mvura yetsvina nekushandisa biochemical action yemicroorganisms.Oiri ihydrocarbon organic matter inogona kuputswa kuita kabhoni dhaikisaidhi nemvura nemabasa ehupenyu akadai semetabolism nemamicroorganisms.Izvo zvinokonzerwa nehupenyu mumvura yakasvibiswa yemafuta inonyanya kunyungudutswa uye emulsified state, uye BOD5 yakakwirira, iyo inobatsira kune biological oxidation.
6. Chemical nzira
Nzira yemakemikari, iyo inozivikanwawo semakemikari nzira, inzira yekuwedzera makemikari kushandura zvinosvibisa mumvura yakasvibiswa kuita zvinhu zvisingakuvadzi nemakemikari chiito, kuitira kuti mvura yakasvibiswa icheneswe.Inowanzo shandiswa makemikari nzira ndeye neutralization, kunaya, coagulation, redox uye zvichingodaro.Coagulation inonyanya kushandiswa kune ine mafuta tsvina.Iyo coagulation nzira ndeyekuwedzera imwe chikamu che flocculant kune ine mafuta tsvina yemvura.Mushure me hydrolysis mumvura, micelle yakachajiswa zvakanaka uye mafuta emulsified anochajiswa anogadzirwa kuti agadzire kusasikwa kwemagetsi, zvidimbu zvemafuta zvakaunganidzwa, saizi yechikamu inova yakakura, uye flocculation inoumbwa panguva imwe chete.Chinhu chakaita semafuta chinoshambadza madonhwe emafuta akatsetseka, uye chobva chapatsanura oiri nemvura nenzira yekunyungudika kana kuyerera kwemhepo.
