01 Kalafo ea mantlha
Karolo ea kalafo ea mochini (ea boemo ba pele) e kenyelletsa meaho e kang li-grilles, li-grit chambers, litanka tsa mantlha tsa sedimentation, joalo-joalo, ho tlosa likaroloana tse mahoashe le lintho tse tiileng tse emisitsoeng.Molao-motheo oa phekolo ke ho finyella karohano e tiileng-metsi ka mekhoa ea 'mele le ho arola litšila tse tsoang ho likhoerekhoere, e leng mokhoa o tloaelehileng oa ho hloekisa likhoerekhoere.
Phekolo ea mochini (ea mantlha) ke morero o hlokahalang bakeng sa lits'ebetso tsohle tsa likhoerekhoere (le hoja mekhoa e meng ka linako tse ling e tlohela tanka ea mantlha ea sedimentation), 'me litekanyetso tse tloaelehileng tsa ho tlosoa ha BOD5 le SS kalafo ea mantlha ea likhoerekhoere tsa litoropo ke 25% le 50%, ka ho latellana. .
Litsing tsa phepelo ea likhoerekhoere tsa phosphorus le naetrojene, liphaposi tsa grit tse nang le moea o motlakase hangata ha li khothalletsoe ho qoba ho tlosoa ha lintho tsa tlhaho tse senyehileng ka potlako;ha litšoaneleho tsa boleng ba metsi a likhoerekhoere tse tala li sa lokele ho tlosoa ha phosphorus le naetrojene, ho hlophisoa ha sedimentation ea mantlha le ho hlophisoa Mokhoa o hloka ho hlahlojoa ka hloko le ho nahanoa ho latela ts'ebetso ea morao-rao ea litšobotsi tsa boleng ba metsi, e le ho etsa bonnete ba. le ho ntlafatsa boleng ba metsi a nang le tšusumetso ea mekhoa ea ho latella joalo ka ho tlosoa ha phosphorus le ho tlosoa ha metsi.
02 Kalafo ea bobeli
Tlhokomelo ea lik'hemik'hale tsa likhoerekhoere ke ea kalafo ea bobeli, ka sepheo sa mantlha sa ho tlosa lintho tse tiileng tse kentsoeng tse ke keng tsa qoelisoa le lintho tse qhibilihang tse qhibilihang.Sebopeho sa eona sa ts'ebetso se fapane, se ka aroloa ka mokhoa oa sludge o kentsoeng, mokhoa oa AB, mokhoa oa A / O, Mokhoa oa A2 / O, mokhoa oa SBR, mokhoa oa ho ntša oxidation, mokhoa oa ho tsitsisa letamo, mokhoa oa CASS, mokhoa oa phekolo ea mobu le mekhoa e meng ea phekolo.Hajoale, boholo ba lits'ebetso tsa likhoerekhoere tsa litoropo li sebelisa mokhoa oa seretse o kentsoeng.
Molao-motheo oa phekolo ea likokoana-hloko ke ho phethela ho bola ha lintho tse phelang le ho qaptjoa ha lintho tse phelang ka ts'ebetso ea likokoana-hloko, haholo-holo ketso ea likokoana-hloko, le ho fetola litšila tse phelang hore e be lihlahisoa tse se nang kotsi tsa khase (CO2), lihlahisoa tsa metsi (metsi) le lihlahisoa tse nang le manyolo. .Sehlahisoa se tiileng (sehlopha sa likokoana-hloko kapa seretse sa likokoana-hloko);litšila tse feteletseng tsa likokoana-hloko li aroloa ho tloha ho tiileng le mokelikeli ka har'a tanka ea sedimentation le ho tlosoa likhoerekhoere tse hloekisitsoeng.the
03 Phekolo ea thuto e phahameng
Phekolo ea thuto e phahameng ke phekolo e tsoetseng pele ea metsi, e leng mokhoa oa ho hloekisa metsi a litšila ka mor'a phekolo ea bobeli, 'me ke mokhoa o phahameng ka ho fetisisa oa ho hloekisa metsi a likhoerekhoere.Hajoale, ha ho na limela tse ngata tsa likhoerekhoere naheng ea rona tse kentsoeng ts'ebetsong e sebetsang.
E hlakisa le ho senya metsi ka mor'a phekolo ea bobeli, e tlosa litšila tse setseng ka metsing ka ho sebelisa carbon adsorption kapa reverse osmosis, 'me e bolaea likokoana-hloko ka ozone kapa chlorine ho bolaea libaktheria le likokoana-hloko, ebe e romela metsi a hloekisitsoeng ka har'a Metsing a sebelisoa e le mehloli ea metsi bakeng sa matloana a hoholang, ho fafatsa literata, ho nosetsa mabanta a matala, metsi a liindasteri le ho thibela mollo.
Ho ka bonoa hore karolo ea ts'ebetso ea ts'ebetso ea likhoerekhoere ke feela ka phetoho ea biodegradation le karohano ea metsi a tiileng, ha a ntse a hloekisa likhoerekhoere le ho ruisa litšila ka har'a seretse, ho kenyelletsa le seretse se ka sehloohong se hlahisoang karolong ea mantlha ea kalafo, The tse setseng activated sludge. e hlahisoang karolong ea bobeli ea phekolo le seretse sa lik'hemik'hale se hlahisoang kalafo ea thuto e phahameng.
Hobane li-sludges tsena li na le palo e kholo ea lintho tse phelang le likokoana-hloko, 'me li senyeha habonolo le ho nkha, ho bonolo ho baka tšilafalo ea bobeli,' me mosebetsi oa ho felisa tšilafalo ha o e-s'o phethoe.Sludge e tlameha ho lahloa ka nepo ka ho fokotsa molumo o itseng, ho fokotsa molumo, ho tsitsisa le kalafo e se nang kotsi.Katleho ea ho hloekisa le ho lahla litšila li na le phello ea bohlokoa setsing sa likhoerekhoere 'me se tlameha ho nkoa ka botebo.
Haeba seretse se sa phekoloe, seretse se tla tlameha ho ntšoa ka mokelikeli o hloekisitsoeng, 'me phello ea tlhoekiso ea semela sa likhoerekhoere e tla felisoa.Ka hona, ts'ebetsong ea 'nete ea kopo, kalafo ea likhoerekhoere ts'ebetsong ea likhoerekhoere le eona e bohlokoa haholo.
04 Mokhoa oa ho ntša monko o monate
Har'a bona, mekhoa ea 'mele haholo-holo e kenyelletsa mokhoa oa dilution, mokhoa oa adsorption, joalo-joalo;mekhoa ea lik'hemik'hale e kenyelletsa mokhoa oa ho monya, mokhoa oa ho chesa, joalo-joalo;shaoara joalo-joalo.
Kamano lipakeng tsa tlhoekiso ea metsi le tlhahlobo ea boleng ba metsi
Ka kakaretso, lisebelisoa tsa tlhahlobo ea boleng ba metsi li tla sebelisoa ts'ebetsong ea ho hloekisa metsi a litšila, e le hore re ka tseba boemo bo itseng ba boleng ba metsi le ho bona hore na bo lumellana le maemo!
Teko ea boleng ba metsi ke ntho e hlokahalang kalafong ea metsi.Mabapi le boemo ba hona joale, metsi a mangata a sebelisoa bophelong le indastering, 'me metsi a litšila bophelong le likhoerekhoere tlhahiso ea indasteri le tsona lia eketseha.Haeba metsi a tsoa ka ho toba ntle le ho tsoa, a ke ke a silafatsa tikoloho feela, empa hape a tla senya haholo tsamaiso ea tikoloho ea tikoloho.Ka hona, ho tlameha ho be le tlhokomeliso ea ho ntša likhoerekhoere le tlhahlobo.Mafapha a amehang a hlalositse matšoao a bohlokoa a ho tsoa bakeng sa tlhoekiso ea metsi.Ke feela ka mor'a ho hlahlojoa le ho netefatsa hore litekanyetso li finyelloa li ka lokolloa.Ho lemoha likhoerekhoere ho kenyelletsa matšoao a mangata, joalo ka pH, lintho tse tiileng tse emisitsoeng, turbidity, tlhokeho ea oksijene ea lik'hemik'hale(COD), tlhokeho ea oksijene ea biochemical(BOD), phosphorus kaofela, naetrojene kaofela, joalo-joalo. standard re ka etsa bonnete ba phello ea ho hloekisa metsi, ho finyella morero oa tšireletso ea tikoloho.
