Zeziphi iipolymers ezisetyenziswa njenge-flocculants?

Inqanaba elibalulekileyo kwinkqubo yokucocwa kwamanzi amdaka kukuzinza nokuxinana kwezinto eziqinileyo ezixhonyiweyo, inkqubo exhomekeke kakhulu kwiikhemikhali ezibizwa ngokubaii-flocculantsKule nto, iipolymers zidlala indima ebalulekileyo, ngoko ke i-PAM, iipolyamines. Eli nqaku liza kujonga kwiipolymer flocculants eziqhelekileyo, ukusetyenziswa kweepolymers njengeeflocculants kunyango lwamanzi amdaka, kunye nemisebenzi esemva kwazo.

Zeziphi ezisetyenziswa rhoqoii-flocculants ze-polymer?

Ii-polymer flocculants ezisetyenziswa rhoqo ziquka ii-cationic polymers, ii-anionic polymers kunye nee-nonionic polymers. Ezi polymers zinokufunyanwa ngeendlela ezahlukeneyo zokwenziwa kwaye zinezakhiwo ezahlukeneyo ze-cationic kunye namasebe. Kwizicelo ezisebenzayo, kuyimfuneko ukukhetha ii-polymer flocculants ezifanelekileyo ngokweemeko ezithile zamanzi amdaka ukuze kufunyanwe isiphumo esihle sonyango. I-PAM, i-polyDADMAC, isetyenziswa kakhulu kunyango lwamanzi amdaka kwimizi-mveliso. I-Polyacrylamide yeyona flocculant isetyenziswa kakhulu kwihlabathi. Ezi polymers zinyibilikayo emanzini zenziwe ngendlela yokwenziwa kwaye zinokwenziwa ngokwezifiso kwizicelo ezithile ngobunzima obahlukeneyo beemolekyuli, i-viscosities, amazinga ahlukeneyo okuhlawula, iintlobo ezahlukeneyo ezifana namasuntswana, ii-emulsions, njl. I-PolyDADMAC isetyenziswa kakhulu emanzini epompo, ukuqunjelwa kwamanzi aluhlaza, ukuphelelwa ngamanzi kodaka, ishishini lephepha kunye nomzi-mveliso wokuprinta nokudaya.

Ukusetyenziswa kweii-flocculants kunyango lwamanzi amdaka

Injongo ephambili yonyango lwamanzi amdaka kukususa ukungcola okufana nezinto eziqinileyo ezixotyulweyo, izinto eziphilayo ezinyibilikisiweyo kunye namasuntswana e-colloidal emanzini ukuphucula umgangatho wamanzi. Kule nkqubo, ii-flocculants zidlala indima ebalulekileyo. Ngokusebenzisa ii-flocculants, amasuntswana amancinci kunye nezinto ze-colloidal emanzini zinokubangela ukuba zihlangane zibe zii-floc ezinkulu, ezinokususwa ngokulula ngokutsalwa okanye ukuhluzwa. Oku akunakuphucula umgangatho wamanzi kuphela, kodwa kukwaphucula nokusebenza kakuhle konyango kunye nokunciphisa iindleko zonyango.

Kutheni iiPolymers zinokwenza ii-flocculants?

Iipolymers zingasetyenziswa njengee-flocculants ngenxa yobunzima bazo obukhulu beemolekyuli kunye nolwakhiwo olunamasebe amaninzi. Ezi mpawu zivumela ipolymer ukuba inamathele ngcono kwi-particle matter, yenze ii-floc ezinkulu ezinokuzinza ngokukhawuleza. Ukongeza, iipolymers zinokuphelisa ukugxojwa kwe-electrostatic phakathi kwee-particles ngokusebenzisa i-charge neutralization, okuvumela ii-particles ukuba zisondele kwaye zihlangane kunye.

Indlela yokusebenza kweepolymers kunyango lwamanzi amdaka

Indlela esebenza ngayo iipolymers njengee-flocculants inokwahlulwa ibe ngamanyathelo amathathu: ukunganyatheli kwetshaja, ukunyenyisa i-flocculation kunye nokubamba i-net. Okokuqala, i-polymer isusa ukugxothwa kwe-electrostatic phakathi kwee-particles ngokusebenzisa ukunganyatheli kwetshaja, ivumela ii-particles ukuba zisondele. Emva koko i-polymer idibanisa ii-particles ukuze zenze ii-floc ezinkulu ngokusebenzisa ukunyenyisa i-flocculation. Ekugqibeleni, ezi floc zihlanganiswa ngakumbi kwaye zihlale emanzini ngokusebenzisa intshukumo yokutshaya ii-net.

Izinto ezichaphazela ukusebenza kakuhle kweePolymers ekuphatheni amanzi amdaka

Kukho izinto ezininzi ezichaphazela ukusebenza kakuhle konyango lwamanzi amdaka nge-polymer, kubandakanya uhlobo lwe-polymer, idosi, ixabiso le-pH, ubushushu, isantya sokuxukuxa, njl. Phakathi kwazo, uhlobo lwe-polymer kunye nedosi zezinye zezinto ezibaluleke kakhulu. Iintlobo ezahlukeneyo ze-polymers zineempawu ezahlukeneyo zokutshaja kunye nokusasazwa kobunzima be-molecular, ngoko ke kuyimfuneko ukukhetha uhlobo lwe-polymer olufanelekileyo kunye nedosi yamanzi amdaka ahlukeneyo ukuze kufezekiswe isiphumo esihle sonyango. Ukongeza, izinto ezifana nexabiso le-pH, ubushushu, kunye nesantya sokuxukuxa nazo ziya kuchaphazela ukusebenza kakuhle konyango, kwaye iimeko ezifanelekileyo kufuneka zichongwe ngokusebenzisa iimvavanyo.

Iipolymers zidlala indima ebalulekileyo njengee-flocculants kunyango lwamanzi amdaka. Ukuqonda okunzulu kwendlela yokusebenza kunye nezinto ezichaphazela iipolymers kunokubonelela ngenkxaso ebalulekileyo yethiyori kunye nesikhokelo esisebenzayo sokuphucula iinkqubo zonyango lwamanzi amdaka kunye nokuphucula ukusebenza kakuhle konyango. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kweemfuno zokhuseleko lokusingqongileyo kunye nokuqhubela phambili okuqhubekayo kwesayensi kunye netekhnoloji, kukholelwa ukuba ukusetyenziswa kweepolymers kunyango lwamanzi amdaka kuya kuba kubanzi ngakumbi nangakumbi.
