Amanzi amdaka kamasipala
Kunyango lwamanzi amdaka asekhaya, i-polyacrylamide inokukhuthaza i-agglutination ekhawulezileyo kunye nokuhlaliswa kwamasuntswana e-turbidity ukuphumeza umphumo wokwahlula kunye nokucaciswa ngokungathathi hlangothi kombane kunye ne-adsorption bridging yayo.Isetyenziselwa ikakhulu ukuhlalisa i-flocculation kwicandelo langaphambili kunye nokucocwa kodaka kwindawo yangasemva yeplanti yokucoca ilindle.
Amanzi alahlwayo kwimizi-mveliso
Xa ukongeza i-polyacrylamide emanzini amasuntswana e-turbidity emisiwe, inokukhuthaza ukuhlanganiswa okukhawulezileyo kunye nokuhlaliswa kwamasuntswana e-turbidity ngokusebenzisa i-neutralization yombane kunye nesiphumo sokuvala i-adsorption yepolymer ngokwayo, kwaye ifezekise isiphumo sokwahlula kunye nokucaciswa, ukuze kuphuculwe ukusebenza kakuhle kunye nokunciphisa iindleko zokusebenza.
Umzi-mveliso wokuprinta kunye nokudaya
Njenge-arhente yokulinganisa kunye ne-ejenti yokugqiba kwilaphu emva konyango, i-polyacrylamide inokuvelisa umaleko okhuselayo othambileyo, ongenamibimbi kunye nokungunda.Ngepropathi eyomeleleyo yehygroscopic, inokunciphisa izinga lokuqhawuka komsonto.Ikwathintela umbane ongatshintshiyo kunye nokuncipha komlilo welaphu.Xa isetyenziswa njengezinto ezincedisayo zokuprinta kunye nokudaya, inokwandisa ukunamathela ngokukhawuleza kunye nokukhanya kwemveliso;Isenokusetyenziswa njenge-non-silicon polymer stabilizer yokucoca.Ukongeza, inokusetyenziselwa ukucocwa okusebenzayo kokuprintwa kwelaphu kunye nokudaya amanzi amdaka.
Ishishini lokwenza amaphepha
I-Polyacrylamide isetyenziswa ngokubanzi njengoncedo lokugcina, uncedo lokucoca kunye ne-dispersant ekwenzeni iphepha.Umsebenzi walo kukuphucula umgangatho wephepha, ukuphucula ukusebenza kwe-dehydration ye-slurry, ukuphucula izinga lokugcinwa kweefayili ezintle kunye nezizaliso, ukunciphisa ukusetyenziswa kwezinto eziluhlaza kunye nokungcola kwendalo.Umphumo wokusetyenziswa kwawo ekwenzeni iphepha kuxhomekeke kumlinganiselo wobunzima bemolekyuli, iimpawu ze-ionic, amandla e-ionic kunye nomsebenzi wezinye ii-copolymers.I-PAM ye-Nonionic isetyenziselwa kakhulu ukuphucula ipropati yokucoca i-pulp, ukwandisa amandla ephepha elomileyo, ukuphucula izinga lokugcinwa kwefiber kunye nokuzalisa;I-Anionic copolymer isetyenziswa kakhulu njenge-ejenti eyomileyo nemanzi kunye ne-agent ehlala ephepheni.I-cationic copolymer isetyenziselwa kakhulu unyango lwamanzi amdaka ephepha kunye ne-filtration aid, kwaye nayo inefuthe elihle ekuphuculeni izinga lokugcinwa kwefayili.Ukongeza, i-PAM iphinda isetyenziswe ekwenzeni unyango lwamanzi amdaka kunye nokubuyiswa kwefiber.
Ishishini lamalahle
Amanzi amdaka okuhlamba amalahle, iplanti yokulungiselela amalahle amanzi amdaka, umzi-mveliso wamalahle ohlamba amanzi amdaka emhlabeni, njl.njl., ngumxube wamanzi kunye nomgubo wamalahle ocolekileyo, iimpawu zawo eziphambili kukudumba okuphezulu, ubungakanani bamasuntswana aqinileyo, umphezulu wamasuntswana aqinileyo. ihlawulwe kakubi ngakumbi, amandla okuhlambalaza phakathi kwentlawulo efanayo yenza la maqhekeza ahlala ehlakazekile emanzini, echatshazelwa yi-gravity kunye ne-Brownian motion;Ngenxa yokusebenzisana phakathi kojongano lwamasuntswana aqinileyo kumanzi amalahle e-slime, iipropathi zamanzi amdaka okuhlamba amalahle zintsonkothile, ezingenazo iipropathi zokunqunyanyiswa kuphela, kodwa zineempawu ze-colloidal.Ukuze wenze amanzi e-slime amalahle aqhube ngokukhawuleza kwi-concentrator, qinisekisa ukuba amanzi okuhlamba afanelekileyo kunye noxinzelelo lwe-slime yokucoca amalahle, kwaye wenze imveliso isebenze ngokufanelekileyo kunye noqoqosho, kuyimfuneko ukukhetha i-flocculant efanelekileyo ukomeleza unyango lwe-slime yamalahle. amanzi.Uthotho lwe-agent ye-polymer flocculation dehydrating ephuhliselwe ukugxothwa kwe-slime yamalahle kwindawo yokuhlamba amalahle inokusebenza okuphezulu kokukhupha amanzi kwaye kulula ukuyisebenzisa.
Amashishini e-elektroniki kunye ne-electroplating
Inkqubo yonyango eqhelekileyo kukulungelelanisa ixabiso le-pH lamanzi amdaka nge-asidi ye-sulfuric ukuya kwi-2 ~ 3 kwi-tank yokuqala yokusabela, emva koko udibanise i-agent yokunciphisa, ulungelelanise ixabiso le-pH kunye ne-NaOH okanye i-Ca (OH) 2 ukuya kwi-7 ~ 8 kwimpendulo elandelayo. itanki ukuvelisa i-Cr(OH)3 yemvula, kwaye emva koko wongeze i-coagulant ukususa i-Cr(OH)3 yemvula.
Isixhobo sokwenza intsimbi
Ikakhulu isetyenziselwa ukuhlambulula amanzi amdaka avela kwirhasi ye-flue ye-oxygen blowing converter, edla ngokubizwa ngokuba ngamanzi amdaka okususa uthuli lomguquli.Ukunyangwa kokuguqulwa kothuli lokususa amanzi amdaka kwintsimbi yensimbi kufuneka kugxininise kunyango lwezinto eziqinileyo ezimisiweyo, ibhalansi yobushushu kunye nokuzinza komgangatho wamanzi.Ukunyangwa kwe-coagulation kunye nemvula yezinto ezimisiweyo kufuneka zisuse ukungcola okumisiweyo kwamaqhekeza amakhulu, kwaye emva koko ungene kwi-sedimentation tank.Yongeza isilawuli se-PH kunye ne-polyacrylamide kumsele ovulekileyo wetanki yentlenga ukufikelela kwi-flocculation eqhelekileyo kunye nentlenga yento enqunyanyisiweyo kunye nesikali kwitanki yentlenga, kwaye wongeze isikali sokuthintela kumanzi amdaka etanki yentlenga.Ngale ndlela, ayisombululi kuphela ingxaki yokucaciswa kwamanzi amdaka, kodwa iphinda isombulule ingxaki yokuzinza kwamanzi, ukuze kufumaneke umphumo ongcono wonyango.I-PAC yongezwa kwi-lindle, kwaye i-polymer flocculates into emisiwe emanzini ibe yi-floc encinci.Xa ugutyulo longeza i-polyacrylamide PAM, ngokusebenzisa iintlobo ngeentlobo zentsebenziswano yebhondi, ukuze ibe yinto ebophelelayo eyomeleleyo yefloc enkulu, ukuze imvula.Ngokwenkqubo, indibaniselwano yePAC kunye nePAM inesiphumo esingcono.
Isityalo semichiza
I-chrominance ephezulu kunye nesiqulatho esingcolisekileyo samanzi amdaka sibangelwa ikakhulu kukungagqibekanga kwemathiriyeli ekrwada okanye isixa esikhulu sesixhobo sokunyibilikisa esisetyenziswa kwimveliso engena kwinkqubo yamanzi amdaka.Zininzi izinto ezingonakaliswa ngebhayoloji, ukungonakaliswa kakuhle kwezinto eziphilayo, izinto eziyityhefu ezininzi neziyingozi, kunye namalungu antsonkothileyo omgangatho wamanzi.I-reaction ekrwada idla ngokuba zizinto ezinyibilikayo okanye iikhompawundi ezinesakhiwo sendandatho, ezandisa ubunzima bokucocwa kwamanzi amdaka.Ukukhetha uhlobo olufanelekileyo lwepolyacrylamide lunokufikelela kwisiphumo esingcono sonyango.
Umzi-mveliso wecuba
Ngasemva kwe-sludge dehydration, ukhetho lwe-polyacrylamide flocculant lunzima, uluhlu lokutshintsha komgangatho wamanzi lukhulu kakhulu, abasebenzi bobugcisa kufuneka banikele ingqalelo kutshintsho lomgangatho wamanzi kwaye benze ukhetho olufanelekileyo lokuvavanya i-agent ye-sludge, umthwalo womsebenzi kwakhona enkulu ngokwentelekiso, ukhetho jikelele cationic Polyacrylamide, iimfuno ubunzima molekyuli ziphezulu ngokwentelekiso, ukuba isantya yokusabela ichiza ngokukhawuleza, ukusetyenziswa kuya kuba ngcono kuneemfuno izixhobo.
Brewery
Unyango ngokuqhelekileyo lwamkelwa itekhnoloji yonyango lwe-aerobic, olufana ne-activated sludge method, umthwalo ophezulu we-biological filtration method kunye nendlela yokudibanisa i-oxidation.Ukusuka kwimeko yangoku, kunokufundwa ukuba i-flocculant esetyenziswa yi-brewery jikelele isebenzisa i-cationic polyacrylamide eqinile, imfuno yobunzima bemolekyuli ingaphezulu kwe-9 yezigidi, umphumo ubonakala kakhulu, umthamo ungaphantsi, iindleko ziphantsi. , kwaye umthamo wamanzi wekeyiki yodaka ecinezelwe sisihluzo nawo uphantsi.
Iplanti yokuvelisa amayeza
Iindlela zonyango ngokubanzi ngolu hlobo lulandelayo: unyango lomzimba kunye neekhemikhali, unyango lwekhemikhali, unyango lwe-biochemical kunye nokudibanisa iindlela ezahlukeneyo, njl. Indlela nganye yonyango ineenzuzo kunye nokungona kwayo.Okwangoku, indlela yokucoca umgangatho wamanzi isetyenziswa ngokubanzi kwinkqubo yokunyangwa kwamanzi amdaka amayeza kunye nasemva kokunyanga, njenge-aluminium sulfate kunye ne-polyferric sulfate esetyenziswa kumanzi amdaka amayeza aseTshayina, njl njl. kunye nokongezwa kweecoagulants ezigqwesileyo.
Umzi-mveliso wokutya
Indlela yesiNtu kukuhlaliswa komzimba kunye nokuvutshelwa kwe-biochemical, kwinkqubo yonyango lwe-biochemical ukusebenzisa i-polymer flocculant, yenza unyango lokukhupha amanzi.I-polymer flocculants esetyenziswe kweli candelo ngokubanzi ziimveliso ze-cationic Polyacrylamide ezineqondo eliphezulu le-ionic kunye nobunzima bemolekyuli.
