一.Ukwethulwa komgomo wohlelo lokusebenza

Phakathi nenqubo yokudweba, izinga lokumboza likapende lingama-40 kuya ku-60% kuphela, futhi ngaphezu kwengxenye kapende usakazekela emoyeni ukuze kwakhe inkungu yesifutho, engcolisa kakhulu umoya nendawo ezungezile. Ukuze kuvikelwe ngempumelelo indawo ezungezile nokuhlanza indawo yokwakha, uhlelo lwamanzi ajikelezayo lwedokodo lokufafaza elimanzi ngokuvamile lisetshenziswa embonini yokudweba ukuze kubanjwe inkungu yopende efakwe ngokweqile. Ukuze kugcinwe ukusebenza kwedokodo lokufutha, kuthuthukiswe indawo yokusebenza yokudweba, nokwenza uhlelo lokuhlanza lusebenze ngokujwayelekile, inani elincane lezinto zamakhemikhali kufanele lengezwe futhi ligcinwe emanzini ajikelezayo, aziwa ngokujwayelekile ngokuthi ama-coagulants enkungu yepende. Ingakwazi ukuxhumana nezinhlayiya zikapende ezibanjwe ngamanzi, bese isabela ngayo futhi iyenze ingasebenzi futhi i-distick, iqoqe i-flocculant enosayizi othile wezinhlayiyana, okuthiwa i-paint slag, futhi ihlukaniswe namanzi, ukuze umjikelezo wamanzi usetshenziswe. isikhathi eside. Ama-coagulant enkungu kapende ikakhulukazi ahlanganisa uhlobo oluqinile lokuhlakazeka kwe-alkali, uhlobo lwe-condensation adsorption, uhlobo lokufingqa lenkungu kapende osekelwe emanzini, njll. Izinhlobo ezingenhla zemikhiqizo zingenza upende u-disticke futhi untante ngezindlela ezilandelayo: yenza inkungu kapende ibe ne-saponification, isuse ukubukeka kwayo. , khiqiza insipho ye-alkali engancibiliki emanzini, ehlakazeke emanzini; Ngesikhathi esifanayo, inkungu kapende ifinyezwa ngokunciphisa ukushajwa kongqimba lwangaphandle lwenkungu kapende. Izinhlayiya ezijiyile ziboshelwa ku-flocculant ngokungqubuzana, bese i-polymer flocculant iyakhangiswa futhi iboshwe ukuze yakhe i-flocculant enkulu.

二.Ungawahlulela kanjani kahle umphumela we-flocculant yenkungu kapende

Umthelela we-coagulant yenkungu kapende ngokuvamile wahlulelwa kusuka ku-slag, amanzi, igwebu, iphunga nokunye.
(1) I-slag yopende: I-viscosity kufanele ibe yincane ngangokunokwenzeka, futhi isilinganiso sokubukeka esibanzi kufanele okungenani sibe ngu-3 kuya ku-4 (i-slag kapende iyi-granular noma isihlabathi esihle).
(2) Amanzi: kudivayisi ye-Eisenmann side flow slagging, ngaphambi kokwengeza i-ejenti B, upende kufanele ube amanzi axubekile ahlakazeke kakhulu, futhi amanzi ngemva kokwengeza i-ejenti B kufanele acace ngangokunokwenzeka, futhi isilinganiso sekhwalithi yamanzi kufanele. okungenani ibe yibanga lesi-3 (ithuthuke kancane).
(3) Igwebu: ukuphakama kwegwebu echibini kufanele kube okufanelekile, futhi akufanele kube ngaphezu kokuphakama kwegwebu elikhiqizwe ngamanzi aqukethe imithi kuphela ngaphansi kwezimo ezifanayo. Igwebu liphezulu kakhulu, libonisa ukuthi umphumela wokuhlukanisa upende namanzi awumuhle.
(4) Iphunga: Phakathi nesikhathi esibekiwe sokusebenza, akukho phunga elingathandeki elisobala okufanele likhiqizwe, okubonisa ukuthi uhlelo lwamanzi lunezingozi ezibangelwa amagciwane anjengesikhunta namabhaktheriya, futhi kungase kubangelwe ukuhlukana kabi kopende namanzi, kodwa ukusetshenziswa kwaso. ama-coagulants enkungu kapende ngeke akhiqize iphunga elicasulayo, futhi ama-coagulant amaningi enkungu kapende anezelwa kuma-antibacterial agents.

三.Izici ezithonya umphumela we-flocculant yenkungu kapende

(1) Izinhlobo zikapende. Nakuba kungekho ukuhlobana okutholakele phakathi kohlobo lwe-resin nomphumela wokusetshenziswa, kuyaziwa ukuthi ama-coagulant enkungu kapende azwela ku-polarity ye-resin. I-coagulant yenkungu kapende ye-polarity ehlukene kanye ne-hydrophilicity kufanele isetshenziswe ngokulandelanayo kumapende we-polarity ehlukene.

(2) PH inani noma i-alkalinity. Kuye kwaziwa ukuthi i-alkalinity efanele noma i-pH inomthelela ekukhipheni upende. Inani le-pH liphezulu kakhulu, upende ucekelwa phansi ngenxa yezinhlayiya ezizinzile ezihlakazekile emanzini okunzima ukuntanta, okuphansi kakhulu akunakubhujiswa ngokuphelele. Ukulawula okujwayelekile kungu-9.0, futhi ukulawula kubaluleke kakhulu ekusebenzeni kwamanzi ajikelezayo.

(3) inqubo yedokodo likapende kanye nenqubo yokupenda yangemva kokwelashwa kwe-slag. Inqubo yegumbi lokupenda isifutho evame ukusetshenziswa kakhulu ihlanganisa uhlobo lokuwasha, uhlobo lwekhethini lamanzi, ikhethini lamanzi - uhlobo lokugeza, uhlobo lwe-swirl yamanzi, uhlobo lwe-Venturi nezinye izinhlobo, kanye nezindlela ezivame ukusetshenziswa zokususa i-slag ngokuyinhloko zihlanganisa ipuleti le-scraper, uhlobo lwe-centrifugal, njll. Inqubo yegumbi lokupenda lokufafaza, izinga lokugeleza kwamanzi elijikelezayo, isivinini, kanye nendlela yokususa i-slag izothinta umphumela wokusetshenziswa.

(4) izici ze-hydrochemical. Ukungcola emanzini, njengokuqina, kuzothinta ubukhulu bezinhlayiya zokusabalalisa upende, ngaleyo ndlela kuthinte ukulahlekelwa kwe-viscosity, ngakho-ke ukuqina kufanele kube kuncane ngangokunokwenzeka. Ukungcola okwethulwa enqubweni yokupenda isifutho, njengezincibilikisi, ikakhulukazi izincibilikisi ezingezona e-polar, kunganciphisa kakhulu amandla okumunca amanzi ukuze kupende inkungu.

(5) Umthamo kanye nendlela yokulinganisa ye-coagulant yenkungu kapende. Uma isilinganiso sincane kakhulu, umphumela wokufingqa awulungile, futhi uma mkhulu kakhulu, unomphumela wokuhlakazeka futhi awukhiqizi ukufingqa. Izinqubo ezihlukene zokumunca upende wedokodo lesifutho zidinga izindlela ezihlukile zokudosa ezifanele, ezidinga ukuhlolwa futhi zinqunywe ekusetshenzisweni kwangempela.

(6) Izinto ezibangelwa amagciwane. Ukuhlushwa kwezinto eziphilayo emanzini ajikelezayo kuphezulu kakhulu, futhi izimo zokusebenza zamanzi ajikelezayo zifanelekile ukukhiqizwa nokukhula kwama-microorganisms. Uma kungalawulwa ngokucophelela, ukuzalaniswa kwama-microorganisms kuzoba nomthelela omubi ekusetshenzisweni kwe-coagulant yenkungu yepende. Ama-bactericidal noma ama-bacteriostatic agents kufanele afakwe njalo lapho izinga lokushisa liphezulu.
