Sei Uchifanira Kusarudza Polyaluminium Chloride Yekurapa Mvura?

Kurapa mvura chikamu chakakosha chekuchengetedzwa kwezvakatipoteredza nehutano hweveruzhinji, uye chinangwa chayo ndechekuona kuti mvura yakachena uye inosangana nezvinodiwa zvekushandiswa kwakasiyana-siyana. Pakati penzira dzakawanda dzekurapa mvura,polyaluminum chloride(PAC) inosarudzwa zvakanyanya nekuda kwehunhu hwayo hwakasiyana uye kushanda kwayo zvakanaka pakugwinya.

Kushanda zvakanaka kwekudzivirira kupwanyika kwemvura: PAC ine simba rakanaka rekudzivirira kupwanyika kwemvura uye inogona kubvisa tsvina yakaita sezvinhu zvakanyungudutswa, macolloid nezvimwe zvinhu zvisinganyunguduke mumvura uye inovandudza kunaka kwemvura.

Maitiro ekubatanidza PAC

Maitiro e polyaluminium chloride (PAC) se coagulant anosanganisira kudzvanywa kwe electric double layer, charge neutralization uye net trapping. Kudzvanywa kwe double electric layer zvinoreva kuti mushure mekuwedzera PAC mumvura, aruminiyamu ions uye chloride ions zvinoumba adsorption layer pamusoro pe colloidal particles, nokudaro zvichidzvanya double electric layer pamusoro pe colloidal particles, zvichiita kuti dzisagadzikana uye dziungane; adsorption bridging ndiyo ma cation ari muma PAC molecules anokwezvana uye negative charges pamusoro pe colloidal particles, zvichigadzira chimiro che "bridge" kuti chibatanidze akawanda colloidal particles; netting effect iri kuburikidza ne adsorption uye bridge effect yema PAC molecules ne colloidal particles, iyo inosunga colloidal particles. Yakabatwa mu network yema coagulant molecules.

Kushandiswa kwemishonga yemvura yePolyaluminum chloride

Kana ichienzaniswa ne inorganic flocculants, yakavandudza zvakanyanya mhedzisiro yekubvisa ruvara rwemadhayi. Maitiro ayo ekushanda ndeekuti PAC inogona kukurudzira mamorekuru edhayi kuti aumbe maflocs akapfava kuburikidza nekudzvanywa kana kuderedzwa kwe electric double layer.

Kana PAM ikashandiswa pamwe chete nePAC, mamorekuru e anionic organic polymer anogona kushandisa bridging effect yemaketani avo marefu emolecular kugadzira mafloc akakora nekubatsirana kwe destabilizing agent. Maitiro aya anobatsira kuvandudza settlement effect uye anoita kuti ma heavy metal ions ave nyore kubvisa. Pamusoro pezvo, huwandu hwakawanda hwema amide groups ari mumaketani edivi ema anionic polyacrylamide molecules hunogona kuumba ionic bonds ne -SON muma dye molecules. Kuumbwa kwechemical bond iyi kunoderedza kunyungudika kwe organic flocculant mumvura, nokudaro zvichikurudzira kuumbwa nekukurumidza uye kunaya kwe flocs. Iyi deep binding mechanism inoita kuti zviomere ma heavy metal ions kutiza, zvichivandudza kushanda uye mhedzisiro yekurapa.

Panyaya yekubvisa phosphorus, kushanda kwepolyaluminum chloride hakugoni kufuratirwa. Kana ikaiswa mumvura yakasviba ine phosphorus, inogona hydrolyze kugadzira maion esimbi ealuminium matatu. Ion iyi inobatanidza nemaphosphate anonyungudika mumvura yakasviba, ichishandura yekupedzisira kuita phosphate precipitates isinganyungudike. Maitiro aya ekushandura anobvisa maion ephosphate mumvura yakasviba uye anoderedza kukanganisa kwakaipa kwephosphorus mumvura.

Pamusoro pekuita zvakananga nephosphate, kuomeswa kwepolyaluminum chloride kunoitawo basa guru mukubvisa phosphorus. Inogona kuunza kunyungudika uye kubatana nekudzvanya charge layer pamusoro pe phosphate ions. Maitiro aya anoita kuti phosphates nezvimwe zvinosvibisa organic mumvura yakasviba zvikurumidze kuomeswa kuita ma clumps, zvichiita kuti zvive nyore kugadzirisa.

Zvinonyanya kukosha ndezvekuti, kune zvinhu zvakapfava zvakasungirirwa zvakagadzirwa mushure mekuwedzera phosphorus removal agent, PAC inoshandisa nzira yayo yekubata mambure uye simba rakasimba rekudzivirira kutsvaira kuti isimudzire kukura zvishoma nezvishoma uye kukora kwezvinhu izvi zvakasungirirwa, uye zvobva zvabatana, zvounganidzwa, uye zvoita zvidimbu zvikuru. Zvinhu izvi zvinozogara pasi, uye kuburikidza nekuparadzaniswa kwemvura yakasimba, mvura inoyerera inogona kuburitswa, nokudaro ichibvisa phosphorus zvakanaka. Iyi nhevedzano yemaitiro akaomarara emuviri nemakemikari inoita kuti mvura yakasviba ishande zvakanaka uye igare zvakanaka, ichipa vimbiso yakasimba yekuchengetedzwa kwezvakatipoteredza uye kushandiswazve kwezviwanikwa zvemvura.
