Ndeapi mapolymer anoshandiswa seFlocculants?

Danho guru mukugadzirisa mvura yakasviba kuomeswa nekugadzika kwezvinhu zvakasungirirwa, maitiro anonyanya kushandiswa pamakemikari anonzi flocculants. Muizvi, mapolymer anoita basa rakakosha, saka PAM, polyamines. Chinyorwa chino chichaongorora zvakajairika.zvinhu zvinogadzira polymer, kushandiswa kwemapolymers semaflocculant mukurapa mvura yakasviba, uye mabasa ari shure kwawo.

Ndezvipi zvinhu zvinoshandiswa zvakanyanya zve polymer flocculants?

Mapolymer flocculant anoshandiswa zvakanyanya anosanganisira cationic polymers, anionic polymers uye nonionic polymers. Mapolymers aya anogona kuwanikwa nenzira dzakasiyana dzekugadzira uye ane cationic uye branched structures dzakasiyana. Mukushanda kwakakosha, zvakakosha kusarudza mapolymer flocculant akakodzera zvichienderana nemamiriro chaiwo emvura yakasviba kuti uwane mhedzisiro yakanaka yekurapa. PAM, polyDADMAC, inoshandiswa zvakanyanya mukurapa mvura yakasviba mumaindasitiri. Polyacrylamide ndiyo flocculant inonyanya kushandiswa pasi rose. Mapolymers aya anonyungudika mumvura akagadzirwa uye anogona kugadzirwa kuti ashandiswe zvakasiyana nehukuru hwakasiyana hwemamorekuru, viscosities, charge degrees dzakasiyana, mafomu akasiyana senge particles, emulsions, nezvimwewo. PolyDADMAC inoshandiswa zvakanyanya mumvura yepombi, flocculation yemvura isina kubikwa, sludge dehydration, indasitiri yemapepa uye indasitiri yekudhinda nekudhaya.

Kushandisa flocculants mukurapa mvura yakasviba

Chinangwa chikuru chekuchenesa mvura yakasviba ndechekubvisa tsvina yakaita sezvinhu zvakanyungudutswa, zvinhu zvakanyungudutswa uye zvinhu zvakasanganiswa mumvura kuti mvura ive nani. Mukuita uku, zvinhu zvakasanganiswa nemvura zvinoita basa rakakosha. Nekushandisa zvinhu zvakasanganiswa nemvura, zvinhu zvidiki uye zvinhu zvakasanganiswa mumvura zvinogona kukonzera kuungana kuita zvinhu zvikuru, izvo zvinogona kubviswa zviri nyore ne sedimentation kana sefiltration. Izvi hazvingogone kuvandudza kunaka kwemvura chete, asiwo zvinovandudza kushanda zvakanaka kwemishonga uye kuderedza mari yekurapa.

Sei maPolymer achigona kugadzira maflocculant?

Mapolymer anogona kushandiswa semaflocculant kunyanya nekuda kwehuremu hwawo hwakawanda hwemamorekuru uye chimiro chawo chine matavi akawanda. Hunhu uhwu hunobvumira polymer kuti inyatsopinda muzvinhu zvidiki, zvichiita kuti mafloc akakura anogona kugara nekukurumidza. Pamusoro pezvo, mapolymer anogona kubvisa electrostatic repulsion pakati pezvikamu kuburikidza ne charge neutralization, zvichibvumira zvikamu kuti zviswedere pedyo uye zviungane pamwe chete.

Maitiro ekushanda kwemapolymers mukurapa mvura yakasviba

Maitiro ekushanda kwemapolymer semaflocculant anogona kukamurwa kuita matanho matatu: kudzikamisa charge, kudzikamisa flocculation uye kubata mambure. Kutanga, polymer inobvisa kudzoserwa kwemagetsi pakati pezvikamu kuburikidza nekudzikamisa charge, zvichiita kuti zvikamu zviswedere pedyo. Polymer inobva yabatanidza zvikamu izvi pamwe chete kuti zvigadzire mafloc makuru kuburikidza nekudzikamisa flocculation. Pakupedzisira, mafloc aya anounganidzwa zvakare uye anogadzikwa mumvura kuburikidza nekushanda kwemambure.

Zvinhu zvinokanganisa kushanda zvakanaka kwemaPolymers pakuchenesa mvura yakasviba

Kune zvinhu zvakawanda zvinokanganisa kushanda zvakanaka kwekugadzirisa mvura yakasviba nepolymer, zvinosanganisira mhando yepolymer, chiyero, pH, tembiricha, kumhanya kwekumutsa, nezvimwewo. Pakati pazvo, mhando yepolymer uye chiyero ndechimwe chezvinhu zvakakosha. Mhando dzakasiyana dzepolymer dzine hunhu hwakasiyana hwekuchaja uye kugoverwa kwehuremu hwemamorekuru, saka zvakakosha kusarudza mhando yepolymer yakakodzera uye chiyero chemvura yakasviba yakasiyana kuti uwane mhedzisiro yakanaka yekurapa. Pamusoro pezvo, zvinhu zvakaita se pH, tembiricha, uye kumhanya kwekumutsa zvichakanganisawo kushanda zvakanaka kwekurapa, uye mamiriro akakodzera anofanirwa kutsanangurwa kuburikidza nekuyedza.

Mapolymers anoita basa rakakosha semaflocculant mukurapa mvura yakasviba. Kunzwisisa kwakadzama mashandiro anoita zvinhu uye zvinhu zvinopesvedzera mapolymers kunogona kupa rutsigiro rwakakosha rwedzidziso uye gwara rinoshanda rekugadzirisa maitiro ekurapa mvura yakasviba uye kuvandudza kushanda zvakanaka kwekurapa. Mune ramangwana, nekuvandudzwa kuri kuramba kuchiitwa kwezvinodiwa zvekuchengetedza zvakatipoteredza uye kufambira mberi kwesainzi netekinoroji, zvinotendwa kuti kushandiswa kwemapolymers mukurapa mvura yakasviba kuchave kwakakura uye kwakadzama.
