Uqwalaselo loqwalaselo izicelo anionic polyacrylamide

I-Anionic polyacrylamide isetyenziselwa ukuqinisa i-flocculation ye-lindle, ineempawu ze-polymer electrolyte kwindawo engathathi hlangothi kunye ne-alkaline, evakalelwa kwi-electrolyte yetyuwa, kunye nexabiso eliphezulu ion yesinyithi inokudityaniswa kwijeli enganyibilikiyo, esetyenziselwa imveliso yasekhaya. amanzi, ukucocwa kogutyulo lwemizi-mveliso kunye nogutyulo lwasezidolophini, kwaye ingasetyenziselwa ukuphelelwa ngamanzi emzimbeni ngodaka.

Iindawo ezintathu eziphambili zesicelo se-anionic polyacrylamide:

Kwishishini lokwenziwa kwesinyithi kunye nesinyithi, isetyenziselwa ukucocwa kwamanzi okuhlamba igesi kwiziko elivulekileyo lomlilo, ukucaciswa kwamanzi amdaka kwizityalo zesinyithi kunye nezityalo zokukha, ukucocwa kwe-electrolytes kunye nokucaciswa kolwelo lwenkunkuma ye-electroplating.

Kwimigodi, isetyenziselwa ukucaciswa kwamanzi okuhlamba amalahle kunye neetailings ezidadayo, ukuhluzwa kwamalahle acocekileyo, iitailings (slag) dehydration, flotation tailings clarification, concentrate thickening and filtration, potassium alkali hot melt kunye flotation processing ukucaciswa kolwelo, ifluorite kunye ne barite flotation tailings. , i-brine ekrwada yokucutshungulwa kwetyuwa, ingcaciso yokuphelelwa ngamanzi emzimbeni ngodaka kunye nonyango lwamanzi lokubuyisela umgodi wephosphate.

Kumanzi amdaka asezidolophini nakwimizi-mveliso, asetyenziselwa ukuphucula ukususwa kwezinto eziqinileyo ezimisiweyo, iBOD kunye nephosphate kumanzi amdaka.Ngokudibanisa i-0.25mg / L i-hydrolyzed polyacrylamide kwi-tank ye-sedimentation yokuqala yamanzi amdaka, amazinga okususwa kwezinto ezimisiweyo kunye ne-BOD inokunyuswa ukuya kwi-66% kunye ne-23%, ngokulandelanayo.Ngokungongeza i-0.3mg / L i-anionic polyacrylamide kwi-tank ye-sedimentation yokucoca amanzi amdaka yesibini, izinga lokususwa kwezinto ezimisiweyo kunye ne-BOD zinokunyuswa ukuya kwi-87% kunye ne-91%, ngokulandelanayo, kunye nesiphumo sokususwa kwe-phosphorus sinokunyuswa ukusuka kwi-35% ukuya kwi-91%. .Kunyango lwamanzi okusela kunye namanzi amdaka asekhaya, asetyenziselwa ukucaciswa komhlaba, ukucaciswa kwamanzi amdaka agungxulwayo kunye nohlengahlengiso lokucoca.

Ukunyibilika kolungiselelo lwe-anionic polyacrylamide lwaziswa:

I-1, esetyenziselwa ukuhlaliswa kwamanzi amdaka, umlinganiselo ocetyiswayo womlinganiselo we-0.1%

I-2, kuqala ngokulinganayo ufefe umgubo emanzini ompompo, kwaye ugxobhoze ngesantya esiphakathi kwe-40-60 RPM ukwenza i-polymer inyibilike ngokupheleleyo emanzini ngaphambi kokuba ifakwe.

3, Ngexesha lovavanyo, thatha i-100ml yamanzi amdaka, yongeza i-10% yesisombululo se-polyacrylamide, kwaye ngokukhawuleza ushukumise, sebenzisa isirinji ukongeza kancinci isisombululo se-PAM, i-0.5ml ngexesha ngalinye, ngokobungakanani bentyatyambo ye-alum eyenziwe kunye nokusondela kwe-flocculant, ukucaca kwe-supernitant, isantya se-sedimentation, i-dosage yokumisela i-arhente efanelekileyo.
