Indle kamasipala
Ekwelapheni indle yasekhaya, i-polyacrylamide ingakhuthaza ukuhlanganiswa okusheshayo nokuxazululwa kwezinhlayiya ze-turbidity ezimisiwe ukuze kuzuzwe umphumela wokuhlukaniswa nokucaciswa nge-neutralization kagesi kanye ne-adsorption bridging yayo.Isetshenziselwa ikakhulukazi ukuhlaliswa kwe-flocculation engxenyeni engaphambili kanye nokukhipha amanzi e-sludge engxenyeni engemuva yesitshalo sokuhlanza indle.
Amanzi angcolile ezimbonini
Lapho ungeza i-polyacrylamide emanzini ezinhlayiya ze-turbidity ezimisiwe, ingakhuthaza ukuhlanganisa okusheshayo nokuxazululwa kwezinhlayiya ze-turbidity ezimisiwe ngokusebenzisa i-neutralization kagesi kanye nomphumela wokuvala i-adsorption we-polymer ngokwayo, futhi uzuze umphumela wokuhlukaniswa nokucaciswa, ukuze kuthuthukiswe ukusebenza kahle kanye nokunciphisa izindleko zokusebenza.
Imboni yokunyathelisa nokudaya izindwangu
Njenge-ejenti yokulinganisa kanye ne-ejenti yokuqedela yendwangu yokwelashwa ngemva kokwelashwa, i-polyacrylamide ingakhiqiza ungqimba oluthambile, oluvikela imibimbi kanye nokuvikela isikhutha.Ngempahla yayo eqinile ye-hygroscopic, inganciphisa izinga lokuphuka lokuphotha kwentambo.Iphinde ivimbele ugesi omile kanye nokuncipha kwelangabi kwendwangu.Uma isetshenziswa njengezisizi zokuphrinta nokudaya, ingathuthukisa ukushesha kokunamathela nokukhanya komkhiqizo;Ingasetshenziswa futhi njenge-non-silicon polymer stabilizer yokuhlanza.Ngaphezu kwalokho, ingasetshenziswa futhi ekuhlanzeni okuphumelelayo kokuphrinta kwendwangu kanye nokudaya amanzi angcolile.
Imboni yokwenza amaphepha
I-Polyacrylamide isetshenziswa kabanzi njengosizo lokugcina, usizo lokuhlunga kanye ne-disperant ekwenzeni iphepha.Umsebenzi wawo ukuthuthukisa ikhwalithi yephepha, ukuthuthukisa ukusebenza kokuphelelwa amandla kwamanzi kwe-slurry, ukuthuthukisa izinga lokugcinwa kwemicu emihle nama-fillers, ukunciphisa ukusetshenziswa kwezinto zokusetshenziswa kanye nokungcoliswa kwemvelo.Umphumela wokusetshenziswa kwayo ekwenzeni iphepha uncike esilinganisweni sesisindo samangqamuzana, izakhiwo ze-ionic, amandla e-ionic kanye nomsebenzi wamanye ama-copolymers.I-Nonionic PAM isetshenziselwa ikakhulukazi ukuthuthukisa impahla yokuhlunga ye-pulp, ukwandisa amandla ephepha elomile, ukuthuthukisa izinga lokugcinwa kwe-fiber kanye nokugcwalisa;I-Anionic copolymer isetshenziswa kakhulu njenge-ejenti yokuqinisa eyomile nemanzi kanye ne-ejenti ehlala ephepheni.I-cationic copolymer isetshenziselwa ikakhulukazi ukwelapha amanzi angcolile okwenza amaphepha kanye nosizo lokuhlunga, futhi iphinde ibe nomthelela omuhle ekuthuthukiseni izinga lokugcinwa kwesigcwalisi.Ngaphezu kwalokho, i-PAM iphinde isetshenziswe ekwelapheni kwamanzi angcolile ngamaphepha kanye nokubuyiswa kwe-fiber.
Imboni yamalahle
Amanzi angcolile okugeza amalahle, amanzi e-slime esitshalo sokulungiselela amalahle, amanzi angcolile okugeza isizinda samandla amalahle emhlabathini, njll., ayingxube yamanzi nempushana yamalahle ecolekileyo, izici zayo eziyinhloko ukuxubeka okuphezulu, usayizi wezinhlayiyana ezincane zezinhlayiya eziqinile, ingaphezulu lezinhlayiya eziqinile ishajwa kabi kakhulu, amandla anyanyekayo phakathi kokushaja okufanayo enza lezi zinhlayiya zihlale zihlakazekile emanzini, zithinteke amandla adonsela phansi kanye nokunyakaza kweBrownian;Ngenxa yokuxhumana phakathi kwe-interface yezinhlayiya eziqinile emanzini we-slime wamalahle, izakhiwo zamanzi angcolile okugeza amalahle ziyinkimbinkimbi kakhulu, ezingenazo izakhiwo zokumiswa kuphela, kodwa futhi zinezakhiwo ze-colloidal.Ukuze wenze amanzi e-slime amalahle ahle ngokushesha ku-concentrator, uqinisekise ukukhiqizwa kwamanzi okugeza okufanelekile kanye nesihlungi sokucindezela amalahle, futhi wenze ukukhiqiza kusebenze kahle futhi ukonga, kuyadingeka ukukhetha i-flocculant efanele ukuqinisa ukuphathwa kwe-slime yamalahle. amanzi.Uchungechunge lwe-ejenti ye-polymer flocculation dehydrating eyenzelwe ukuchithwa kwe-slime yamalahle endaweni yokuwasha amalahle inokusebenza kahle okuphezulu kokukhipha amanzi futhi kulula ukuyisebenzisa.
Izimboni zikagesi neze-electroplating
Inqubo evamile yokwelapha ukulungisa inani le-pH lamanzi angcolile nge-sulfuric acid liye ku-2 ~ 3 ethangini lokuqala lokusabela, bese wengeza i-ejenti yokunciphisa, ulungise inani le-pH nge-NaOH noma i-Ca(OH)2 ukuya ku-7 ~ 8 ekuphenduleni okulandelayo. ithangi ukukhiqiza imvula engu-Cr(OH)3, bese wengeza i-coagulant ukuze ususe imvula engu-Cr(OH)3.
Isitshalo sokwenza insimbi
Ngokuyinhloko isetshenziselwa ukuhlanza amanzi angcolile kusukela kugesi we-flue we-oxygen evuthela isiguquli, okuvame ukubizwa ngokuthi amanzi angcolile okukhipha uthuli we-converter.Ukwelashwa kwamanzi angcolile okususwa kothuli lwesiguquli esigayweni sensimbi kufanele kugxile ekwelapheni okuqinile okumisiwe, ibhalansi yokushisa kanye nokuzinza kwekhwalithi yamanzi.I-coagulation kanye nokwelashwa kwemvula yento emisiwe idinga ukususa ukungcola okumisiwe kwezinhlayiya ezinkulu, bese ifaka ithangi le-sedimentation.Engeza isilawuli se-PH kanye ne-polyacrylamide emgodini ovulekile wethangi le-sedimentation ukuze uzuze ukugeleza okuvamile kanye ne-sedimentation yento emisiwe nesikali ethangini le-sedimentation, bese wengeza inhibitor yesikali emanzini angcolile ethangi le-sedimentation.Ngale ndlela, ayixazululi kuphela inkinga yokucaciswa kwamanzi angcolile, kodwa futhi ixazulula inkinga yokuzinza kwamanzi, ukuze kuzuzwe umphumela ongcono wokwelapha.I-PAC yengezwa endle, futhi i-polymer ihambisa indaba emisiwe emanzini ibe yi-floc encane.Lapho indle wanezela polyacrylamide PAM, ngokusebenzisa ezihlukahlukene isibopho ukubambisana, ukuze ibe amandla aqinile okubopha of floc emikhulu, ukuze kwezulu.Ngokwalo mkhuba, inhlanganisela ye-PAC ne-PAM inomphumela ongcono.
Isitshalo samakhemikhali
I-chrominance ephezulu kanye nokuqukethwe okungcolile kwamanzi angcolile kubangelwa ikakhulukazi ukusabela kwempahla eluhlaza okungaphelele noma inani elikhulu le-solvent medium esetshenziswa ekukhiqizeni kungena ohlelweni lwamanzi angcolile.Ziningi izinto ezibolayo, ukubola kwe-biodegradable, izinto ezinobuthi eziningi neziyingozi, kanye nezingxenye zekhwalithi yamanzi eziyinkimbinkimbi.Izinto ezisetshenziswayo zokusabela ngokuvamile ziyizinto ezincibilikayo noma izinhlanganisela ngesakhiwo sendandatho, okwandisa ubunzima bokwelashwa kwamanzi angcolile.Ukukhetha uhlobo olufanele lwe-polyacrylamide lungafinyelela umphumela ongcono wokwelashwa.
Imboni kagwayi
Ngemuva kwe-sludge dehydration, ukukhethwa kwe-polyacrylamide flocculant kunzima, ububanzi bokushintshwa kwekhwalithi yamanzi bukhulu kakhulu, abasebenzi bezobuchwepheshe kufanele banake ukuguqulwa kwekhwalithi yamanzi futhi benze ukukhetha okufanelekile kokuhlolwa kwe-ejenti ye-sludge dehydrating, umthwalo wokusebenza futhi kukhulu, ukukhethwa okuvamile kwe-cationic polyacrylamide, izidingo zesisindo samangqamuzana ziphakeme kakhulu, uma isivinini sokusabela kwezidakamizwa sishesha, ukusebenziseka kuyoba ngcono kunezidingo zemishini.
Bkabusha
Ukwelashwa ngokuvamile kwamukelwa ubuchwepheshe bokwelapha be-aerobic, obufana nendlela yodaka olucushiwe, indlela yokuhlunga yebhayoloji enomthwalo omkhulu kanye nendlela ye-oxidation yokuxhumana.Kusukela esimweni samanje, kungafundwa ukuthi i-flocculant esetshenziswa i-brewery jikelele ngokuvamile isebenzisa i-cationic polyacrylamide eqinile, imfuneko yesisindo samangqamuzana ingaphezu kwezigidi ezingu-9, umphumela uvelele kakhulu, umthamo ungaphansi, izindleko ziphansi kakhulu. , futhi okuqukethwe kwamanzi ekhekhe lodaka elicindezelwe isisefo nakho kuphansi kakhulu.
Imboni yokukhiqiza imithi
Izindlela zokwelapha ngokuvamile zimi kanje: ukwelashwa ngokomzimba namakhemikhali, ukwelashwa kwamakhemikhali, ukwelashwa kwamakhemikhali kanye nokuhlanganiswa kwezindlela ezihlukahlukene, njll. Indlela yokwelapha ngayinye inezinzuzo zayo kanye nokubi.Njengamanje, indlela yokwelapha ikhwalithi yamanzi isetshenziswa kabanzi enqubweni yokwelashwa kwamanzi angcolile emithi kanye nokwelashwa ngemva kokwelashwa, njenge-aluminium sulfate kanye ne-polyferric sulfate esetshenziswa emanzini angcolile emithi yamaShayina, njll. Ukhiye wokwelashwa okuhlangene okusebenzayo usekukhethweni okufanele. kanye nokwengezwa kwama-coagulants amahle kakhulu.
Imboni yokudla
Indlela yendabuko iwukuhlala ngokomzimba kanye nokuvutshelwa kwamakhemikhali ezinto eziphilayo, enqubweni yokwelashwa kwamakhemikhali ezinto eziphilayo ukusebenzisa i-polymer flocculant, ukwenza ukwelashwa kokukhipha amanzi ngodaka.I-polymer flocculants esetshenziswe kulesi sigaba ngokuvamile yimikhiqizo ye-cationic polyacrylamide ene-ionic degree ephakeme kakhulu nesisindo samangqamuzana.
