Kokubili kufakwe emiyalweni yokusebenzisa
Kuyini i-flocculation? Ngemva kokufaka i-coagulant emanzini angavuthiwe, ixubana ngokuphelele nomzimba wamanzi, iningi lokungcola kwe-colloid emanzini lilahlekelwa ukuqina, futhi izinhlayiya ze-colloid ezingazinzile ziyashayisana bese zihlangana echibini le-flocculation, bese zakha i-floc engasuswa ngendlela yemvula.
Izici ezithonya i-flocculation
Inqubo yokukhula kwe-floc inqubo yokuxhumana nokushayisana kwezinhlayiya ezincane.
Ikhwalithi yomphumela we-flocculation incike ezintweni ezimbili ezilandelayo:
1 ikhono lama-polymer complexes akhiwe yi-coagulant hydrolysis ukwakha ibhuloho lohlaka lwe-adsorption, elinqunywa yizakhiwo zama-coagulants
2 amathuba okushayisana kwezinhlayiya ezincane nokuthi ungazilawula kanjani ukuze kushayisane ngendlela efanele nephumelelayo. Imikhakha yobunjiniyela bokwelashwa kwamanzi ikholelwa ukuthi ukuze kwandiswe amathuba okushayisana, i-gradient yesivinini kumele yandiswe, futhi ukusetshenziswa kwamandla emzimbeni wamanzi kumele kwandiswe ngokwandisa i-gradient yesivinini, okungukuthi, ukwandisa ijubane lokugeleza kwechibi lokugeleza (isengezo: uma izinhlayiya zihlangana futhi zikhula ngokushesha kakhulu ekugelezeni, zizobhujiswa. Kunezinkinga ezimbili: ukukhula kwe-floc oku-1 ngokushesha kakhulu amandla ayo ayancipha, enkambisweni yokugeleza ehlangatshezwayo ukucheba okunamandla kuzokwenza ibhuloho lohlaka lokumunca linqunywe, ibhuloho lohlaka lokumunca elinqunyiwe kunzima ukuqhubeka likhuphuke, ngakho-ke inqubo yokumunca nayo iyinqubo elinganiselwe, ngokukhula kwe-floc, ijubane lokugeleza kufanele lincishiswe, ukuze i-floc eyakhiwe ingabi lula ukuphuka; 2 ukukhula kwe-floc okusheshayo kakhulu kuzokwenza indawo ethile yobuso be-floc yamanzi incishiswe kakhulu, okunye ukusabela akuphelele izinhlayiya ezincane ezilahlekile izimo zokusabela, lezi zinhlayiya ezincane kanye namathuba okushayisana kwezinhlayiya ezinkulu ancishiswe kakhulu, kunzima ukukhula futhi, lezi zinhlayiya azikwazi kuphela ngenxa Uma ithangi lokuthungwa ligcinwe, kunzima futhi ukuligcina njengesihlungi.)
Engeza izidingo
Esigabeni sokuqala sokusabela kokwengeza i-coagulant, kuyadingeka ukwandisa amathuba okuxhumana nendle ngangokunokwenzeka, ukwandisa izinga lokuxuba noma lokugeleza. Kuye ngokushayisana kokugeleza kwamanzi nepuleti lokugoqa kanye nokugeleza kwamanzi phakathi kwepuleti lokugoqa ukwandisa isivinini, ukuze ithuba lokushayisana kwezinhlayiya zamanzi lande, ukuze ukuminyana kwe-floc. Futhi ekuphenduleni kwangemva kwesikhathi, ukuze kuncishiswe i-gradient yesivinini, kungathola umphumela we-flocculation ongcono kanye nokwehla kwemvula.
Ukwengeza imishini: isitsha semithi, ithangi lokugcina imithi, isixubho sokulinganisa, iphampu yokulinganisa kanye nemishini yokulinganisa. Ihlonyiswe ngokusebenzisa izindlela
I-PAC, ukuhlushwa kokusabalalisa kwe-PAM (kukhishwe esikhwameni sokupakisha izidakamizwa bese kwengezwa ethangini lokuncibilikisa) Ukuhlushwa kokusabalalisa kwe-PAC kanye ne-PAM Ngokusho kokuhlangenwe nakho: Ukuhlushwa kwedamu lokuncibilikisa le-PAC okungu-5%-10%, ukuhlushwa kwe-PAM okungu-0.1%-0.3%, idatha engenhla ilingana nekhwalithi, okungukuthi, amanzi angama-cubic angu-PAC angu-50-100kg, i-PAM 1-3kg. Lokhu kuhlushwa kuphakeme kakhulu, umthamo wokuncibilikisa we-PAM unqunyelwe, kudingeka uvuselele ngokugcwele isivinini esiphakathi ukuze uncibilikise ngokuphelele. Ehlobo, ukuhlushwa kokusabalalisa kwe-PAM kungandiswa kahle kube ngu-0.3-0.5%. Thatha ukuhlushwa kokusabalalisa kwe-PAC okungu-10%, ukuhlushwa kokusabalalisa kwe-PAM okungu-0.5%, bese kuthi wonke amanzi angama-cubic ancibilikisiwe e-PAC100kg, i-PAM5kg, lungisa ukugeleza kwephampu yemitha yokugeleza ye-diaphragm, ngokusho kokubala kwe-cubic meter engu-1 / amahora angama-24, okungukuthi, i-Q = amalitha angu-42 / ihora, ingafinyelela umphumela omuhle kakhulu wokuhlanza indle. Isilinganiso se-PAC, i-PAM se-sewage treatment agent (encibilikisiwe emanzini okuqala) Isilinganiso se-sewage treatment agent ngokuvamile yi-PAC 50-100ppm, i-PAM 2-5ppm, iyunithi ye-ppm iyisigidi esisodwa, ngakho-ke iguqulwa ibe amagremu angu-50-100 e-PAC ngethani lendle, amagremu angu-2-5 e-PAM, kunconywa ukuthi ngokuvamile ngokusho kwalesi sivivinyo sesilinganiso. Uma umthamo wokwelapha indle wansuku zonke ungamamitha ayi-cubic angu-2000, ukuhlushwa kwesilinganiso se-PAC ngokusho kwe-50ppm, ukuhlushwa kwesilinganiso se-PAM ngokusho kwesibalo se-2ppm, khona-ke umthamo we-PAC wansuku zonke ungama-100kg, umthamo we-PAM ungama-4kg. Isilinganiso esingenhla sibalwa ngokusho kokuhlangenwe nakho okuvamile, umthamo othize kanye nokuhlushwa kwesilinganiso kudingeka kusekelwe ekuhlolweni okuthile kwekhwalithi yamanzi. Bala inani elibekiwe kumitha yokugeleza kwepompo yokulinganisa.
Ngemva kokufaka i-ejenti emanzini angcolile noma odakeni, kufanele ixutshwe ngempumelelo. Isikhathi sokuxuba ngokuvamile siyimizuzwana eyi-10-30, ngokuvamile kungabi ngaphezu kwemizuzu emi-2. Umthamo othize we-ejenti kanye nokuhlushwa kwezinhlayiya ze-colloidal, izinto eziqinile ezilengisiwe emanzini angcolile noma odakeni, uhlobo kanye nemishini yokwelapha kunobudlelwano obuhle, umthamo wokwelapha odakeni kwabanye, umthamo ongcono kakhulu utholakala ngenani elikhulu lokuhlola. Ngokusho kokuhlushwa komthamo ongcono kakhulu (ppm1 ukwengeza ukuhlushwa) kanye nokugeleza kwamanzi (t/h) kanye nokucushwa kokuhlushwa kwesisombululo (ukuhlushwa kokulungiselela i-ppm2), kungabalwa enanini lokubonisa i-flowmeter yepompo yokulinganisa (LPM). Inani lokubonisa le-flowmeter yepompo yokulinganisa (LPM) = ukugeleza kwamanzi (t/h)/60×PPM1 ukwengeza ukuhlushwa / ukuhlushwa kokulungiselela i-PPM2.
Qaphela: i-ppm iyisigidi esisodwa; inani lamayunithi e-flowmeter yephampu yokulinganisa, i-LPM ngamalitha/umzuzu; i-GPM ngamagaloni/umzuzu
