Iiflocculants zePolyacrylamide zisebenza kakhulu ekususeni amanzi kwidaka nasekuhlaliseni amanzi amdaka. Abanye abathengi baxela ukuba i-polyacrylamide pam esetyenziswa ekususeni amanzi kwidaka iya kudibana neengxaki ezinjalo nezinye. Namhlanje, ndiza kuhlalutya iingxaki ezininzi eziqhelekileyo kuye wonke umntu.
1. Isiphumo se-flocculation se-polyacrylamide asilungile, kwaye yintoni isizathu sokuba ingenakucinezelwa kwi-sludge? Ukuba isiphumo se-flocculation asilungile, kufuneka siqale sisuse iingxaki zomgangatho wemveliso ye-flocculant ngokwayo, nokuba i-cationic polyacrylamide iyahlangabezana nomgangatho wobunzima be-ionic molecular, kunye nesiphumo sokucocwa kwamanzi semveliso engahlangabezani nomgangatho. Ngokuqinisekileyo ayilunganga. Kule meko, ukutshintsha i-PAM ngenqanaba le-ion elifanelekileyo kunokusombulula ingxaki.
2. Ndingenza ntoni ukuba ubungakanani be-polyacrylamide bukhulu kakhulu?
Isixa esikhulu sithetha ukuba umxholo wesalathisi semveliso awanelanga, kwaye kukho umsantsa phakathi kwezalathisi ezifunekayo kwi-polyacrylamide kunye ne-sludge flocculation. Ngeli xesha, kufuneka ukhethe uhlobo kwakhona, ukhethe imodeli efanelekileyo ye-PAM kunye nesixa sokongeza ukuze uvavanye, kwaye ufumane ixabiso lokusetyenziswa elingabizi kakhulu. Ngokubanzi, kucetyiswa ukuba uxinzelelo olunyibilikisiweyo lwe-polyacrylamide lube yi-1-1000 ukuya kwi-2-2000, kwaye ukhetho oluncinci lovavanyo lwenziwa ngokweli xinzelelo, kwaye iziphumo ezifunyenweyo zifanelekile ngakumbi.
3. Ndingenza ntoni ukuba i-viscosity ye-sludge emva kokusebenzisa i-polyacrylamide ekususeni amanzi kwi-sludge iphezulu?
Le meko ibangelwa kukongezwa kakhulu kwe-polyacrylamide okanye imveliso engafanelekanga kunye nodaka. Ukuba i-viscosity yodaka iyancipha emva kokunciphisa ubungakanani bokongeza, ngoko ke yingxaki yobungakanani bokongeza. Ukuba ubungakanani bokongeza buncitshisiwe, isiphumo asifumaneki kwaye udaka alunakucinezelwa, ngoko ke yingxaki yokukhetha imveliso.
4. I-Polyacrylamide yongezwa kwi-slidge, kwaye umxholo wamanzi wekhekhe lodaka elilandelayo uphezulu kakhulu, ndingenza ntoni ukuba ikhekhe lodaka alomi ngokwaneleyo?
Kwimeko enjalo, qala ujonge izixhobo zokuphelisa amanzi emzimbeni. Umatshini webhanti kufuneka ujonge ukuba ukunwebeka kwelaphu lokucoca akwanelanga na, ukuba amanzi angena njani kwilaphu lokucoca kwaye ukuba ilaphu lokucoca kufuneka litshintshwe na; ipleyiti kunye nefreyimu yesihluzo kufuneka zijonge ukuba ixesha loxinzelelo lwesihluzo lanele na, nokuba uxinzelelo lwesihluzo lufanelekile na; i-centrifuge kufuneka ijonge ukuba ukhetho lwearhente yokuphelisa amanzi emzimbeni lufanelekile na. Izixhobo zokuphelisa amanzi emzimbeni ezihlanganisiweyo zigxile ekujongeni ukuba ubunzima bemolekyuli ye-polyacrylamide buphezulu kakhulu na, kwaye iimveliso ezine-viscosity ephezulu kakhulu azilungelanga ukucinezela udaka!
Kusekho iingxaki ezininzi eziqhelekileyo ze-polyacrylamide ekususeni amanzi kwi-sludge. Ezi zingentla zezona ngxaki zixhaphakileyo kunye nezisombululo ezishwankathelwe kwinani elikhulu lokulungisa iimpazamo kwindawo. Ukuba unemibuzo malunga nokucinezelwa kwe-cationic polyacrylamide sludge okanye ukutsalwa kwenkunkuma, konke Ungasithumelela i-imeyile, masithethe ngokusetyenziswa kwe-polyacrylamide ekususeni amanzi kwi-sludge!
