Kwintsimi yoshishino, ukusetyenziswa okudityanisiweyo kwe-polyaluminium chloride (PAC) kunye ne-polyacrylamide (PAM) ukunyanga amanzi amdaka kunye nenkunkuma efanayo yenze ikhonkco lobuchwepheshe obuqolileyo, kodwa indlela yokusebenza kwayo edibeneyo ayicaci, kwaye umlinganiselo wedosi kwiimeko ezahlukeneyo zokusebenza kwi imimandla eyahlukeneyo nayo yahlukile.
Eli phepha lihlalutya ngokubanzi inani elikhulu loncwadi olufanelekileyo ekhaya naphesheya, lishwankathela inkqubo edityanisiweyo yePAC nePAC, kwaye lenza amanani-nkcazo abanzi ngezigqibo ezahlukeneyo ezinobungqina ngokudityaniswa nefuthe lokwenyani lePAC nePAM kumashishini ahlukeneyo, enentsingiselo ebalulekileyo. kuphando olongezelelweyo kwiinkalo ezinxulumeneyo.
1. Umzekelo wophando lwesicelo sasekhaya se-pac-pam
Umphumo we-crosslinking we-PAC kunye ne-PAM isetyenziswe kuzo zonke iindlela zobomi, kodwa i-dosage kunye neendlela ezixhasayo zonyango zihluke kwiimeko ezahlukeneyo zokusebenza kunye neendawo zonyango.
1.1 ilindle lasekhaya kunye nodaka lukamasipala
UZhao Yueyang (2013) kunye nabanye bavavanya i-coagulation effect ye-PAM njenge-coagulant aid kwi-PAC kunye ne-PAFC ngokusebenzisa indlela yovavanyo lwangaphakathi.Uvavanyo lufumanise ukuba isiphumo sokudityaniswa kwePAC emva komanyano lwePAM lwandiswe kakhulu.
U-Wang Mutong (2010) kunye nabanye bafunda umphumo wonyango we-PAC + PA kwi-lindle yasekhaya edolophini, kwaye bafunda ukususwa kwe-COD ngokufanelekileyo kunye nezinye izibonakaliso ngokusebenzisa iimvavanyo ze-orthogonal.
Lin yingzi (2014) et al.Ufunde impembelelo yokudibanisa eyongeziweyo yePAC kunye ne-PAM kwi-algae kwindawo yokucoca amanzi.UYang Hongmei (2017) et al.Ufunde umphumo wokonyango wokusetyenziswa okudibeneyo kumanzi amdaka e-kimchi, kwaye kuqwalaselwe ukuba ixabiso le-pH elilungileyo laliyi-6.
UFu peiqian (2008) et al.Uphonononge isiphumo se-flocculant ehlanganisiweyo esetyenziselwa ukusetyenziswa kwakhona kwamanzi.Ngokulinganisa imiphumo yokususwa kwezinto ezingcolileyo ezifana ne-turbidity, i-TP, i-COD kunye ne-phosphate kwiisampuli zamanzi, kufunyenwe ukuba i-flocculant edibeneyo inefuthe elihle lokususa kuzo zonke iintlobo zokungcola.
I-Cao Longtian (2012) kunye nabanye bamkela indlela yokudibanisa i-composite ukusombulula iingxaki zesantya sokuphendula ngokucothayo, i-flocs yokukhanya kunye nobunzima bokutshona kwinkqubo yokucoca amanzi e-Northeast China ngenxa yobushushu obuphantsi ebusika.
U-Liu Hao (2015) et al.Ufunde umphumo wokonyango we-composite flocculant kwi-sedimentation enzima kunye nokunciphisa ukuchithwa kwe-turbidity ekumisweni kwamanzi amdaka asekhaya, kwaye wafumanisa ukuba ukongeza inani elithile le-PAM flocculate ngelixa ukongeza i-PAM kunye ne-PAC kunokukhuthaza umphumo wokugqibela wonyango.
1.2 ukuprinta kunye nokudaya amanzi amdaka kunye namanzi amdaka okwenza amaphepha
Zhang Lanhe (2015) et al.Ufunde isiphumo solungelelwaniso lwe-chitosan (CTS) kunye ne-coagulant kunyango lwamanzi amdaka enziwe ngamaphepha, kwaye wafumanisa ukuba kungcono ukongeza i-chitosan.
Amazinga okususwa kwe-COD kunye ne-turbidity anyuswe nge-13.2% kunye ne-5.9%.
U-Xie Lin (2010) wafunda umphumo wePAC kunye ne-PAM edibeneyo yonyango lwamanzi amdaka ephepha.
U-Liu Zhiqiang (2013) kunye nabanye basebenzisa i-PAC kunye ne-PAC edibeneyo i-flocculant edibeneyo kunye ne-ultrasonic ukunyanga ukuprinta kunye nokudaya amanzi amdaka.Kwagqitywa ukuba xa ixabiso le-pH liphakathi kwe-11 kunye ne-13, i-PAC yongezwa kuqala kwaye ixutywe imizuzu emi-2, kwaye emva koko iPAC yongezwa kwaye ixutywe imizuzu emi-3, umphumo wonyango wawungcono.
UZhou Danni (2016) kunye nabanye bafunda umphumo wonyango we-PAC + PAM kumanzi amdaka asekhaya, xa kuthelekiswa nefuthe lonyango lwe-biological accelerator kunye ne-antidote ye-biological, kwaye bafumanisa ukuba i-PAC + PAM yayingcono kunendlela yonyango lwe-biological kwimpembelelo yokususwa kweoli, kodwa I-PAC + PAM yayingcono kakhulu kunendlela yonyango lwebhayoloji kwityhefu yomgangatho wamanzi.
Wang Zhizhi (2014) et al.Ufunde indlela yonyango yokunyanga amanzi amdaka aphakathi kwe-PAC + PAM njengenxalenye yendlela.Xa i-dosage yePAC i-250 mg / L, i-dosage ye-PAM yi-0.7 mg / L, kwaye ixabiso le-pH liphantse lingathathi hlangothi, izinga lokususa i-COD lifikelela kuma-68%.
UZuo Weiyuan (2018) kunye nabanye bafunda kwaye bathelekisa umphumo odibeneyo we-flocculation we-Fe3O4 / PAC / PAM.Uvavanyo lubonisa ukuba xa umlinganiselo wezo zintathu yi-1: 2: 1, umphumo wonyango wokuprinta kunye nokudaya amanzi amdaka ngowona ungcono.
LV sining (2010) et al.Ufunde umphumo wonyango wePAC + PAM indibaniselwano kumanzi amdaka aphakathi.Uphando lubonisa ukuba i-composite flocculation effect iyona nto ingcono kwi-acidic environment (pH 5).Idosi yePAC yi-1200 mg / L, idosi ye-PAM yi-120 mg / L, kwaye izinga lokususa ikhowudi lingaphezulu kwe-60%.
1.3 amanzi amdaka ekhemikhali yamalahle kunye nokucokisa amanzi amdaka
UYang Lei (2013) et al.Ufunde i-coagulation effect ye-PAC + PAM kushishino lwamalahle kunyango lwamanzi amdaka, uthelekisa i-turbidity eshiyekileyo phantsi komlinganiselo ohlukeneyo, kwaye wanika idosi ehlengahlengisiweyo ye-PAM ngokuhambelana ne-turbidity yokuqala eyahlukileyo.
UFang Xiaoling (2014) kunye nabanye bathelekisa umphumo we-coagulation wePAC + Chi kunye nePAC + PAM kumanzi amdaka okucoca.Baye bagqiba ekubeni i-PAC + Chi yayinempembelelo engcono ye-flocculation kunye nokusebenza okuphezulu kokususa i-COD.Iziphumo zovavanyo zibonise ukuba elona xesha lokuvuselelayo laliyi-10 min kwaye elona xabiso liphezulu le-pH laliyi-7.
UDeng Lei (2017) et al.Ufunde impembelelo ye-flocculation ye-PAC + PAM kwi-drilling fluid emdaka, kwaye izinga lokususa i-COD lifikelele ngaphezu kwe-80%.
Wu Jinhua (2017) et al.Ufunde ngonyango lwamanzi amdaka ekhemikhali yamalahle ngokujiya.I-PAC yi-2 g / L kunye ne-PAM yi-1 mg / L. uvavanyo lubonisa ukuba ixabiso elihle le-pH liyi-8.
UGuo Jinling (2009) et al.Ufunde umphumo wokucoca amanzi we-composite flocculation kwaye waqwalasela ukuba umphumo wokususa wawungcono xa idosi ye-PAC yayingu-24 mg / L kunye ne-PAM yi-0.3 mg / L.
ULin Lu (2015) et al.Ufunde impembelelo ye-flocculation ye-pac-pam indibaniselwano kwi-oyile e-emulsified equkethe amanzi amdaka phantsi kweemeko ezahlukeneyo, kwaye uthelekise umphumo we-flocculant enye.Idosi yokugqibela yile: PAC 30 mg / L, pam6 mg / L, ubushushu be-ambient 40 ℃, ixabiso le-pH elingathathi hlangothi kunye nexesha lentlenga elingaphezu kwe-30 min.Ngaphantsi kwezona meko zilungileyo, ukusebenza kakuhle kokususa i-COD kufikelela malunga ne-85%.
2 isiphelo kunye neengcebiso
Ukudibanisa i-polyaluminium chloride (PAC) kunye ne-polyacrylamide (PAM) isetyenziswe ngokubanzi kuzo zonke iinkalo zobomi.Inamandla amakhulu kummandla wamanzi amdaka kunye nonyango lwe-sludge, kwaye ixabiso layo lemizi-mveliso lifuna ukuphononongwa ngakumbi.
Indlela yokudibanisa ye-PAC kunye ne-PAM ikakhulu ixhomekeke kwi-ductility egqwesileyo ye-PAM ye-macromolecular chain, idibaniswe ne-Al3 + kwi-PAC kunye ne-O kwi-PAM ukwenza isakhiwo sothungelwano esizinzile.Isakhiwo sothungelwano sinokuzinza imvulophu obunye ubumdaka obunje ngamasuntswana aqinileyo kunye namathontsi e-oyile, ngoko ke inesiphumo esihle sonyango lwamanzi amdaka aneentlobo ezininzi zokungcola, ngakumbi ukuhlalisana kweoli kunye namanzi.
Kwangaxeshanye, indibaniselwano yePAC kunye nePAM nayo ineziphene.Umxholo wamanzi we-flocculate eyenziweyo uphezulu, kwaye isakhiwo sayo sangaphakathi esizinzile sikhokelela kwiimfuno eziphezulu zonyango lwesibini.Ke ngoko, uphuhliso olongezelelweyo lwePAC ludityaniswe nePAM lusajongene nobunzima kunye nemingeni.
