32% okuqukethwe:lokhu kwenziwa ngokumisa isifutho, kuhlukile kweminye imikhiqizo, lokhu kubukeka kwePAC kumhlophe, ukuhlanzeka okuphezulu kwe-polyaluminium chloride engeyona ayoni, ikakhulukazi esetshenziswa embonini yamakhemikhali emihle kanye nokukhiqizwa kwezimonyo, kungokwebanga lokudla.

I-Polyacrylamide:ebizwa ngokuthi i-PA M, eyaziwa ngokuthi i-flocculant noma i-coagulant

Isimiso:I-PAM ye-molecular chain kanye nesigaba esihlakazekile ngokusebenzisa izinhlobonhlobo zemishini, ngokomzimba, amakhemikhali neminye imiphumela, isigaba esihlakazekile esixhunywe ndawonye, ​​​​sakha inethiwekhi, ngaleyo ndlela sithuthukise indima.

Ukusebenza:I-PAM iyimpushana emhlophe, encibilika emanzini, cishe ayincibiliki ku-benzene, ether, lipids, acetone nezinye izinyibilikisi zemvelo ezijwayelekile, i-polyacrylamide isixazululo samanzi sicishe sikhanye obala, siyimpahla engeyona ingozi, engeyona eyingozi, engagqwali, eqinile. I-PAM ine-hygroscopicity, i-hygroscopicity iyanda ngokunyuka kwe-ionic degree.

Umfanekiso womkhiqizo

Ukuhlukaniswa okuvamile

I-PAM ngokwezici zayo zeqembu elihlukanisayo ihlukaniswe i-anionic polyacrylamide, i-cationic polyacrylamide ne-polyacrylamide engeyona ionic.I-polyacrylamide ye-Ionic.

I-Cationic PAM:udaka olucushiwe olukhiqizwa indlela ye-biochemical

I-Anionic PAM:indle nodaka olunecala elihle, njengemboni yensimbi, imboni ye-electroplating, i-metallurgy, ukugeza amalahle, ukususwa kothuli nezinye indle, kunomthelela ongcono

I-Nonionic PAM:ngoba i-cationic ne-anionic inomphumela omuhle, kodwa inani leyunithi libiza kakhulu, ngokuvamile alivamile ukusetshenziswa

Kokubili kwengezwe ukuze kusetshenziswe imiyalelo

Iyini i-flocculation?Ngemva kokwengeza i-coagulant emanzini aluhlaza, exube ngokugcwele namanzi, ukungcola okuningi okusemanzini alahlekelwa ukuzinza, futhi izinhlayiya ze-colloid ezingaqinile ziyashayisana futhi zijiyane ku-flocculation pool, bese kwakheka i-floc engasuswa ngendlela yemvula.

Izici ezinomthelela we-flocculation

Inqubo yokukhula kwe-floc yinqubo yokuthintana nokushayisana kwezinhlayiya ezincane.

Ikhwalithi yomphumela we-flocculation incike ezintweni ezimbili ezilandelayo:

1 ikhono le-polymer complexes elakhiwe yi-coagulant hydrolysis ukwakha ibhuloho le-adsorption frame, elinqunywa izakhiwo zama-coagulants.

2 amathuba okushayisana kwezinhlayiya ezincane kanye nendlela yokulawula ukungqubuzana okunengqondo nokusebenzayo.Imikhakha yobunjiniyela bokwelashwa kwamanzi ikholelwa ukuthi ukuze kwandiswe amathuba okushayisana, isivinini kufanele sinyuswe, futhi ukusetshenziswa kwamandla emanzini kufanele kukhuliswe. ukwanda ngokukhuphula isivinini se-speed gradient, okungukuthi, ukwandisa isivinini sokugeleza kwe-flocculation pool (i-addendum: uma izinhlayiya zihlangana futhi zikhula ngokushesha kakhulu ekugelezeni, zizobhujiswa. Kunezinkinga ezimbili: ukukhula kwe-floc oku-1 ngokushesha kakhulu amandla ayo buthaka, enqubweni yokugeleza okuhlangene nokugunda okuqinile kuzokwenza ibhuloho lohlaka lwe-adsorption linqanyulwe, ibhuloho elinqunyiwe lohlaka lwe-adsorption kunzima ukuqhubeka, ngakho-ke inqubo ye-flocculation nayo iyinqubo elinganiselwe, ngokukhula kwe-floc, ukugeleza kwesivinini kufanele. kuncishiswe, ukuze floc kwakheka akulula ukuba ephukile 2 ezinye floc ukukhula fast too uzokwenza amanzi floc ethize surface endaweni ziyancipha, abanye ukusabela akuyona ephelele izinhlayiya ezincane elahlekile izimo zokusabela, lezi zinhlayiya ezincane kanye nezinhlayiya ezinkulu ukungqubuzana; Amathuba ancipha kakhulu, kunzima ukukhula futhi, lezi zinhlayiya azikwazi nje kuphela ethangini le-sedimentation eligciniwe, futhi kunzima ukuligcina isihlungi.)

Engeza izidingo

Esigabeni sokuqala sokusabela kokwengeza i-coagulant, kuyadingeka ukwandisa ithuba lokuxhumana ne-sewage ngangokunokwenzeka, ukwandisa izinga lokuxutshwa noma lokugeleza. ipuleti eligoqayo ukuze kukhuliswe isivinini, ukuze ithuba lokungqubuzana kwezinhlayiya zamanzi likhule, ukuze i-floc condensation.Futhi ekuphenduleni sekwephuzile, ukuze kuncishiswe isivinini, ingathola ukugeleza okungcono, umphumela wezulu.

Ingeza okokusebenza:isitsha sezidakamizwa, ithange lokugcina izidakamizwa, isivunguvungu sokudosa, iphampu yokudosa kanye nemishini yokukala.Ihlonyiswe ngokusetshenziswa kwezindlela

I-PAC, i-PAM yokugxilisa yokukhipha izidakamizwa (ekhishwe esikhwameni sokupakisha izidakamizwa futhi yengezwa ethangini lokuhlakaza)I-PAC ne-PAM yokusatshalaliswa kwe-PAM Ngokwesipiliyoni: I-PAC dissolution pool concentration ka-5% -10%, i-PAM concentration ka-0.1% -0.3%, i- idatha engaphezulu ngokulingana nekhwalithi, okungukuthi, wonke amanzi ayi-cubic PAC 50-100kg, PAM 1-3kg.Lokhu kuhlushwa kuphakeme kakhulu, umthamo wokuhlakazeka we-PAM unomkhawulo, udinga ukunyakazisa ngokugcwele isivinini esiphakathi nendawo ukuze incibilike ngokuphelele. Ukugxiliswa kwe-PAM kokuncibilika kunganyuswa ngokufanelekile kuye ku-0.3-0.5%.Thatha ukugxiliswa kwe-PAC kokuchithwa kuka-10%, ukugxiliswa kwe-PAM kokuqedwa kuka-0.5%, bese kuthi wonke amanzi ayi-cubic ancibilike PAC100kg, PAM5kg, lungisa ukugeleza kwepompo lemitha yokugeleza kwe-diaphragm, ngokuya ngemitha eyi-cubic meter. / 24 amahora wokubala, okungukuthi, Q = 42 amalitha / ihora, kungafinyelela ekahle ukwelashwa indle flocculation umphumela.I-PAC, i-PAM isikali somenzeli wokuhlanza indle (encibilikiswe emanzini okuqala)Isilinganiso se-ejenti yokuhlanza indle ngokuvamile siyi-PAC 50-100ppm, PAM 2-5ppm, iyunithi ye-ppm iyisigidi esisodwa, ngakho siguqulelwa ku-50-100 amagremu we-PAC ngethani lokukhucululwa kwendle, 2-5 amagremu we-PAM, kunconywa ukuthi ngokuvamile ngokwalokhu kuhlolwa komthamo. 100kg, umthamo we-PAM ngu-4kg. Umthamo ongenhla ubalwa ngokuvumelana nolwazi olujwayelekile, umthamo othize kanye nokugxiliswa komthamo kudingeka kusekelwe ekuhloleni okuthile kwekhwalithi yamanzi.Bala inani elimisiwe kumitha yokugeleza kwephampu yedosi

Ngemuva kokungeza i-ejenti emanzini angcolile noma ama-sludge, kufanele ihlanganiswe ngokuphumelelayo.Isikhathi sokuxuba ngokuvamile siyimizuzwana eyi-10-30, ngokuvamile ayidluli imizuzu emi-2.Umthamo othize we-ejenti kanye nokugcwala kwezinhlayiya ze-colloidal, okuqinile okumisiwe kundle noma udaka, imvelo nemishini yokwelapha inobudlelwano obukhulu, umthamo wokwelapha udaka kwabanye, umthamo ongcono kakhulu utholakala ngenani elikhulu lokuhlola. ukugxiliswa komthamo okungcono kakhulu (ppm1 ukwengeza ukugxilisa ingqondo) nokugeleza kwamanzi (t/h) kanye nokucushwa kokugxiliswa kwesisombululo (ukugxila kokulungiswa kwe-ppm2), kungabalwa ngevelu yokubonisa iphampu ye-dosing flowmeter (LPM). dosing futha flowmeter (LPM) = ukugeleza kwamanzi (t/h)/60×PPM1 ukwengeza ukugxila /PPM2 ukulungiselela ukugxila.

Qaphela: i-ppm yisigidi; umthamo wephampu flowmeter value amayunithi, LPM litha/umzuzu;GPM ingamagalani/umzuzu
