Khopolo ea chlorine e setseng
Residual chlorine ke palo ea chlorine e fumanehang e setseng ka metsing ka mor'a hore metsi a hloekisoe le ho tšeloa likokoana-hloko.
Karolo ena ea chlorine e eketsoa nakong ea ts'ebetso ea ho hloekisa metsi ho bolaea libaktheria, likokoana-hloko, lintho tse phelang le lintho tse sa tloaelehang ka metsing. Masala a chlorine ke sesupo sa bohlokoa sa phello ea ho thibela likokoana-hloko ea libaka tsa metsi. Masala a chlorine a ka aroloa ka mekhahlelo e 'meli, e leng masala a chlorine a mahala le masala a chlorine a kopaneng. Masala a chlorine a mahala haholo-holo a kenyelletsa chlorine ea mahala ka mokhoa oa Cl2, HOCl, OCl-, joalo-joalo; Masala a chlorine a kopantsoeng ke chloramine e hlahisoang ka mor'a karabelo ea chlorine e sa lefelloeng le lintho tsa ammonium, joalo ka NH2Cl, NHCl2, NCl3, joalo-joalo. e kopantsoeng le chlorine e setseng.
Palo ea masala a chlorine hangata e lekantsoe ka limiligrama ho litara. Palo ea masala a chlorine e lokela ho ba e loketseng, eseng holimo haholo kapa tlase haholo. Klorine e setseng e phahame haholo e tla etsa hore metsi a nkhe monko, ha chlorine e setseng e le tlase haholo e ka etsa hore metsi a lahleheloe ke bokhoni ba 'ona ba ho boloka likokoana-hloko le ho fokotsa polokeho ea bohloeki ea phepelo ea metsi. Ka hona, kalafong ea metsi a pompo, boemo ba masala a chlorine hangata bo hlahlojoa le ho lokisoa ho netefatsa polokeho le boleng ba boleng ba metsi.
Karolo ea chlorine ho phekoleng likhoerekhoere tsa litoropong
1. Karolo ea chlorine disinfection
Chlorination ke mokhoa o sebelisoang hangata oa ho bolaea likokoana-hloko bakeng sa ho hloekisa likhoerekhoere tsa litoropo. Mesebetsi ea eona ea mantlha ke e latelang:
1. Phello e ntle ea disinfection
Ka ho hloekisa likhoerekhoere, chlorine e ka bolaea boholo ba libaktheria le likokoana-hloko. Chlorine inactivates microorganisms ka ho oxidizing liprotheine tsa tsona le nucleic acid. Ho phaella moo, chlorine e ka bolaea mahe le li-cysts tsa likokoana-hloko tse ling.
2. Phello ea oxidizing boleng ba metsi
Ho eketsa chlorine ho ka boela ha etsa oxidize organic matter ka metsing, ho etsa hore lintho tse phelang li bole hore e be inorganic acid, carbon dioxide le lintho tse ling. Chlorine e kopana le lintho tse phelang metsing ho hlahisa li-oxidants tse kang hypochlorous acid le chlorine monoxide, e leng tsona tse bolisang lintho tse phelang.
3. Thibela ho hōla ha baktheria
Ho eketsa chlorine e lekaneng ho ka thibela kholo ea likokoana-hloko tse ling, ho fokotsa bongata ba seretse ka tanka ea ho arabela, le ho fokotsa bothata le litšenyehelo tsa phekolo e latelang.
2. Melemo le Mefokolo ea Khlorine Disinfection
1. Melemo
(1) Tšusumetso e ntle ea ho bolaea likokoana-hloko: Tekanyo e nepahetseng ea chlorine e ka bolaea boholo ba libaktheria le livaerase.
(2) Dosing e bonolo: Thepa ea chlorine dosing e na le sebopeho se bonolo ebile e bonolo ho e hlokomela.
(3) Theko e tlase: Theko ea thepa ea ho fana ka chlorine e tlase ebile e bonolo ho e reka.
2. Mefokolo
(1) Chlorine e hlahisa lintho tse kotsi tse kang hypochloronitrile: Ha chlorine e kopana le lintho tse phelang tse nang le naetrojene, ho hlahisoa lintho tse kotsi tse kang hypochloronitrile, tse tla baka tšilafalo ea tikoloho.
(2) Bothata ba masala a chlorine: Lihlahisoa tse ling tsa chlorine ha li fetohe 'me li tla lula metsing, tse amang tšebeliso ea metsi e latelang kapa mathata a tikoloho.
3. Litaba tse hlokang ho eloa hloko ha u eketsa chlorine
1. Khatiso ea chlorine
Haeba mahloriso a chlorine a le tlase haholo, phello ea ho thibela likokoana-hloko e ke ke ea finyelloa 'me likhoerekhoere li ke ke tsa phekoloa ka katleho; haeba motsoako oa chlorine o phahame haholo, karolo e setseng ea chlorine metsing e tla ba e phahameng, e bakang kotsi 'meleng oa motho.
2. Nako ea ente ea chlorine
Nako ea ente ea chlorine e lokela ho khethoa nakong ea ho qetela ea tsamaiso ea tsamaiso ea likhoerekhoere ho thibela likhoerekhoere hore li se ke tsa lahleheloa ke chlorine kapa ho hlahisa lihlahisoa tse ling tsa ho belisoa ka mekhoa e meng, kahoo li ama phello ea ho thibela likokoana-hloko.
3. Khetho ea lihlahisoa tsa chlorine
Lihlahisoa tse fapaneng tsa chlorine li na le litheko le litšoantšiso tse fapaneng 'marakeng, mme khetho ea lihlahisoa e lokela ho ipapisa le maemo a itseng.
Ka bokhutšoanyane, ho eketsa chlorine ke e 'ngoe ea mekhoa e sebetsang ea ho hloekisa likhoerekhoere tsa litoropo le ho thibela likokoana-hloko. Ts'ebetsong ea ho hloekisa likhoerekhoere, tšebeliso e utloahalang le ente ea chlorine e ka netefatsa polokeho ea boleng ba metsi ka nepo le ho ntlafatsa ts'ebetso ea ho hloekisa likhoerekhoere. Leha ho le joalo, ho boetse ho na le lintlha tse ling tsa tekheniki le litaba tsa ts'ireletso ea tikoloho tse hlokang ho eloa hloko ha u eketsa chlorine.
Hobaneng ha chlorine e eketsoa kalafo ea metsi:
Mokhahlelong oa mokelikeli oa limela tsa ho hloekisa metsi a pompo le likhoerekhoere, mokhoa oa ho thibela likokoana-hloko oa chlorine o sebelisoa haholo ho bolaea libaktheria le likokoana-hloko ka metsing. Phekolong ea metsi a pholileng a potolohang indastering, ho sebelisoa chlorine sterilization le ts'ebetso ea ho tlosa algae, hobane nakong ea ts'ebetso ea ho potoloha ha metsi a pholileng, ka lebaka la mouoane oa karolo ea metsi, limatlafatsi tse metsing li tsepame, libaktheria le likokoana-hloko tse ling. e tla ata ka bongata, 'me ho bonolo ho etsa slime Litšila, seretse se feteletseng le litšila li ka baka tšitiso ea liphaephe le ho bola.
Haeba karolo e setseng ea chlorine metsing a pompo e phahame haholo, likotsi tse ka sehloohong ke tsena:
1. E halefisa haholo ebile e kotsi tsamaisong ea ho hema.
2. E sebetsana habonolo le lintho tse phelang metsing ho hlahisa lik'hemik'hale tse kang chloroform le chloroform.
3. Joaloka lihlahisoa tse tala tsa tlhahiso, e ka 'na ea e-ba le liphello tse mpe. Ka mohlala, ha e sebelisoa ho hlahisa lihlahisoa tsa veine ea raese, e na le phello ea baktheria tomosong nakong ea ho belisoa 'me e ama boleng ba veine. Hobane chlorine hangata e sebelisoa ho hloekisa metsi a pompo, 'me chlorine e setseng e tla hlahisa lik'hemik'hale tse kang chloroform nakong ea ho futhumatsa. Ho noa nako e telele ho tla baka kotsi e kholo 'meleng oa motho. Haholo-holo lilemong tsa morao tjena, tšilafalo ea mehloli ea metsi e se e le mpe le ho feta, e leng se lebisang ka ho toba keketseho ea masala a chlorine metsing a pompo.
Mekhoa ea ho lekanya bakeng sa chlorine e setseng ke efe?
1. DPD colorimetry
.
Molao-motheo: Tlas'a maemo a pH 6.2 ~ 6.5, ClO2 e qala ho sebetsana le DPD mohatong oa 1 ho hlahisa motsoako o mofubelu, empa chelete e bonahala e fihla feela ho karolo ea bohlano ea kakaretso ea eona e fumanehang ea chlorine (e lekanang le ho fokotsa ClO2 ho chlorite ion) e le 'ngoe. Haeba sampole ea metsi e e-na le asiti ka boteng ba iodide, chlorite le chlorate le tsona li arabela, 'me ha li se na lehlakore ka ho eketsoa ha bicarbonate,' mala o hlahisoang o lumellana le kakaretso e fumanehang ea chlorine ea ClO2. Tšitiso ea chlorine ea mahala e ka laoloa ka ho eketsa glycine. Motheo ke hore glycine e ka fetola hang-hang chlorine ea mahala hore e be chlorinated aminoacetic acid, empa ha e na phello ho ClO2.
2. Mokhoa oa electrode o koahetsoeng
Molao-motheo: Electrode e qoelisoa ka kamoreng ea electrolyte, 'me kamore ea electrolyte e kopana le metsi ka lera la porous hydrophilic. Hypochlorous acid e kenella ka har'a sekoti sa electrolyte ka lera la porous hydrophilic, e etsang hore e be hona joale holim'a electrode. Boholo ba hona joale bo itšetlehile ka lebelo leo asiti ea hypochlorous e kenang ka har'a sekoti sa electrolyte. Sekhahla sa phallo se lekana le masala a chlorine mothapong. Lekanya boholo ba hona joale. Bongata ba chlorine e setseng ka tharollo bo ka khethoa.
.
3. Mokhoa oa kamehla oa li-electrode tsa motlakase (mokhoa oa electrode o se nang membrane)
.
Molao-motheo: Monyetla o tsitsitseng o bolokiloe pakeng tsa li-electrode tsa tekanyo le litšupiso, 'me likarolo tse fapaneng tse lekantsoeng li tla hlahisa matla a fapaneng a hona joale ka bokhoni bona. E na le li-electrode tse peli tsa platinum le electrode ea referense ho theha tsamaiso ea tekanyo ea microcurrent. Ho electrode ea ho lekanya, limolek'hule tsa chlorine kapa hypochlorite lia jeoa, 'me matla a hona joale a hlahisoang a amana le ho bokellana ha chlorine e setseng ka metsing.
Sesebelisoa sa ho metha sa chlorine sa Lianhua sa LH-P3CLO se sebelisa mokhoa oa ho lemoha oa DPD, o bonolo ho sebetsa mme o ka hlahisa litholoana kapele. U hloka feela ho eketsa li-reagents tse 2 le sampole e lokelang ho lekoa, 'me u ka fumana liphetho tsa papiso ea mebala. Lethathamo la litekanyo le pharaletseng, litlhoko li bonolo, 'me liphello li nepahetse.
