Uqwalaselo lwamanqanaba okusetyenziswa kwe-anionic polyacrylamide

I-Anionic polyacrylamide isetyenziswa kakhulu ekuqiniseni ukutyibilika kwamanzi amdaka, ineempawu ze-polymer electrolyte kwi-neutral kunye ne-alkaline medium, inovelwano kwi-electrolytes zetyuwa, kwaye ii-ion zesinyithi ezibiza kakhulu zinokudityaniswa zibe yi-gel enganyibilikiyo, esetyenziselwa kakhulu imveliso yamanzi yasekhaya, unyango lwamanzi amdaka kwimizi-mveliso nasezidolophini, kwaye ingasetyenziselwa nokuphelelwa ngamanzi kodaka olungaphiliyo.

Iindawo ezintathu eziphambili zokusetyenziswa kwe-anionic polyacrylamide:

Kwishishini lokuvelisa i-cast kunye nesinyithi, isetyenziselwa ukucoca amanzi okuhlamba igesi kwisithando esivulekileyo, ukucacisa amanzi amdaka kwizityalo ze-powder metallurgy kunye nezityalo zokuqhotsa, ukucocwa kwee-electrolytes kunye nokucacisa ulwelo lwenkunkuma ye-electroplating.

Kwimigodi, isetyenziselwa ukucacisa amanzi okuhlamba amalahle kunye neentsalela zerhasi, ukuhluzwa kwamalahle okucocekileyo, ukuphelelwa ngamanzi (i-slag), ukucaciswa kwentsalela zerhasi, ukuqiniswa kunye nokucoca intsalela, ukunyibilika kwe-potassium alkali eshushu kunye nokulungiswa kolwelo, ukucaciswa kwentsalela zerhasi ye-fluorite kunye ne-barite, i-brine eluhlaza yokucubungula ityuwa, ukucaciswa kokuphelelwa ngamanzi kwerhasi kunye nonyango lwamanzi okubuyisela imigodi ye-phosphate.

Kwindlela yokucoca amanzi amdaka asezidolophini nakwezoshishino, isetyenziselwa ukuphucula ukususwa kwezinto eziqinileyo ezixhonyiweyo, i-BOD kunye ne-phosphate emanzini amdaka. Ngokudibanisa i-0.25mg/L ye-hydrolyzed polyacrylamide kwi-primary water sedimentation tank, amazinga okususwa kwezinto ezixhonyiweyo kunye ne-BOD anokwandiswa ukuya kwi-66% kunye ne-23%, ngokulandelelana. Ngokudibanisa i-0.3mg/L ye-anionic polyacrylamide kwi-secondary water waste treatment sedimentation tank, izinga lokususwa kwezinto ezixhonyiweyo kunye ne-BOD linokwandiswa ukuya kwi-87% kunye ne-91%, ngokulandelelana, kwaye isiphumo sokususwa kwe-phosphorus sinokunyuswa ukusuka kwi-35% ukuya kwi-91%. Ekulungiseni amanzi okusela kunye namanzi amdaka asekhaya, isetyenziselwa ukucacisa umphezulu, ukucacisa amanzi amdaka ahlanjwayo kunye nokulungiswa kwe-filtrate.

Ukunyibilika kokulungiselela i-anionic polyacrylamide kuqaliswa:

1, esetyenziswa kwiindawo zokuhlala amanzi amdaka, umlinganiselo ocetyiswayo woxinzelelo lwe-0.1%

2, qala ngokufafaza umgubo ngokulinganayo emanzini epompo, uze uxube ngesantya esiphakathi se-40-60 RPM ukuze i-polymer inyibilike ngokupheleleyo emanzini ngaphambi kokuba yongezwe.

3, Ngexesha lovavanyo, thatha amanzi amdaka ayi-100ml, yongeza isisombululo se-polyacrylamide esiyi-10%, uze uvuselele kancinci, sebenzisa isirinji ukongeza kancinci isisombululo se-PAM, i-0.5ml ngalo lonke ixesha, ngokobukhulu bentyatyambo ye-alum evelisiweyo kunye nokuba ikufutshane kwe-flocculant, ukucaca kwe-supernitant, izinga lokutsalwa kwenkunkuma, idosi yokumisela iarhente efanelekileyo.
