Iiflocculants zePolyacrylamide zisebenza kakhulu ekugxothweni kodaka kunye nokulungiswa kwelindle. Abanye abathengi baxela ukuba i-polyacrylamide pam esetyenziswa ekugxothweni kodaka iya kudibana nezinye iingxaki. Namhlanje, ndiza kuhlalutya iingxaki ezininzi eziqhelekileyo kumntu wonke. :
1. Impembelelo ye-flocculation ye-polyacrylamide ayilungile, kwaye yintoni isizathu sokuba ingacinezeleki kwi-sludge? Ukuba umphumo we-flocculation awulungile, kufuneka siqale sisuse iingxaki zomgangatho wemveliso ye-flocculant ngokwayo, nokuba i-cationic polyacrylamide idibana ne-ionic ye-molecular weight standard, kunye ne-sludge dewatering effect yemveliso engahambelani nomgangatho Ngokuqinisekileyo ayilunganga. . Kule meko, ukutshintsha i-PAM kunye nenqanaba le-ion elifanelekileyo kunokusombulula ingxaki.
2. Ndingenza ntoni ukuba isixa sepolyacrylamide sikhulu kakhulu?
Isixa esikhulu sithetha ukuba umxholo wesalathiso wemveliso awanelanga, kwaye kukho umsantsa phakathi kwezalathisi ezifunekayo kwi-polyacrylamide kunye ne-sludge flocculation. Ngeli xesha, kufuneka ukhethe uhlobo kwakhona, khetha imodeli efanelekileyo ye-PAM kunye nemali yokongeza ukuvavanya, kwaye ufumane ukusetyenziswa kwezoqoqosho. iindleko. Ngokuqhelekileyo, kucetyiswa ukuba i-concentration edibeneyo ye-polyacrylamide i-1-000 ukuya kumawaka amabini, kunye nokukhethwa kovavanyo oluncinci lwenziwa ngokuhambelana nolu luhlu, kwaye iziphumo ezifunyenweyo zinengqiqo.
3.Yintoni endimele ndiyenze ukuba i-viscosity ye-sludge emva kokusebenzisa i-polyacrylamide kwi-sludge dewatering iphezulu?
Le meko ibangelwa ukongezwa ngokugqithiseleyo kwe-polyacrylamide okanye imveliso engafanelekanga kunye ne-sludge. Ukuba i-viscosity ye-sludge iyancipha emva kokunciphisa inani elongezelelweyo, ngoko ke yingxaki yemali eyongezelelweyo. Ukuba inani elongezelelweyo liyancitshiswa, umphumo awufezeki kwaye i-sludge ayikwazi ukucinezelwa, ngoko ke yingxaki yokukhethwa kwemveliso.
4. I-Polyacrylamide yongezwa kwi-sludge, kwaye umthamo wamanzi wekhekhe lodaka olulandelayo uphezulu kakhulu, yintoni endimele ndiyenze ukuba ikhekhe lodaka alomile ngokwaneleyo?
Kule meko, jonga kuqala izixhobo zokuchithwa kwamanzi. Umatshini webhanti kufuneka ujonge ukuba ukolulwa kwelaphu lokucoca akwanelanga, ukungenwa kwamanzi kwelaphu lokucoca kunye nokuba ilaphu lokucoca kufuneka litshintshwe; ipleyiti kunye nesakhelo sokucoca ukucoca kufuneka kukhangelwe ukuba ixesha loxinzelelo lokucoca lanele, Ingaba uxinzelelo lwesihluzi lufanelekile; i-centrifuge idinga ukujonga ukuba ngaba ukukhethwa kwe-agent ye-dehydrating ifanelekile. I-Screw egciniweyo kunye ne-decanter dehydration igxininise ekujongeni ukuba ubunzima be-molecular polyacrylamide buphezulu kakhulu, kwaye iimveliso ezine-viscosity ephezulu kakhulu azihambisani nokucofa udaka!
Kusekho iingxaki ezininzi eziqhelekileyo zepolyacrylamide ekugxothweni kodaka. Ezi zingasentla zezona ngxaki zixhaphakileyo kunye nezisombululo ezishwankathelweyo kwinani elikhulu lolungiso lweempazamo kwisiza. Ukuba unemibuzo malunga ne-cationic polyacrylamide sludge pressing or sedimentation, yonke Ungathumela i-imeyile kuthi, makhe sixoxe ngokusetyenziswa kwe-polyacrylamide kwi-sludge dewatering!
Iphinde yashicilelwa kwi-Qingyuan Wan Muchun yoqobo.
