Ukuze kukhutshelwe okanye kuphinde kusetyenziswe aManzi amdaka emva koNyango, iintlobo ngeentlobo zeMichiza kufuneka zisetyenziswe kwinkqubo yokuCocwa koGutyulo.Namhlanje,PAM (Polyacrylamide) ababoneleliuya kukuxelela malunga neeflocculants:
I-Flocculant: Ngamanye amaxesha ikwabizwa ngokuba yi-coagulant, inokusetyenziswa njengendlela yokuqinisa ukwahlula okuqinileyo-olwelwelo, kwaye inokusetyenziswa kwitanki yokumisa ephambili, itanki yokumisa okwesibini, itanki ye-flotation, unyango oluphezulu okanye unyango oluphambili kunye namanye amakhonkco enkqubo.
I-Flocculants isetyenziswe njengendlela yokomeleza ukuhlukana okuqinileyo-olwelwelo kwintsimi yokucoca ukungcola.Zingasetyenziselwa ukomeleza intlenge yokuqala yelindle, unyango lweflotation kunye nesedimentation yesibini emva kwenkqubo yodaka olusebenzayo, kwaye ingasetyenziselwa unyango oluphezulu okanye unyango oluphezulu lwelindle.Xa isetyenziselwa ukulungiswa kwemeko ngaphambi kokuphelelwa ngamanzi emzimbeni kwe-sludge engaphezulu, i-flocculants kunye ne-coagulants iba yi-sludge conditioners okanye i-dehydrating agents.
Xa usebenzisa i-flocculants yendabuko, indlela yokongeza i-coagulant aids ingasetyenziselwa ukuphucula umphumo we-flocculation.Umzekelo, ukusebenzisa i-asilicic acid esebenzayo njenge-coagulant yoncedo lwe-inorganic flocculants njenge-ferrous sulfate kunye ne-aluminium sulfate kwaye ukongeza ngokulandelelana kunokufikelela kwi-flocculation efanelekileyo.Ke ngoko, ngokwemiqathango ye-layman, i-IPF ye-polymer flocculant ye-inorganic ilungiswe ngokudibanisa i-coagulant aid kunye ne-flocculant kwaye yongezwa kunye ukwenza lula umsebenzi womsebenzisi.
Ukunyangwa kwe-coagulation ngokuqhelekileyo kubekwe phambi kwendawo yokwahlula okuqinileyo-ulwelo, kwaye kudityaniswe nendawo yokwahlula, kunokususa ngokufanelekileyo izinto eziqinileyo ezimisiweyo kunye ne-colloidal kunye nobungakanani bamasuntswana e-1nm ukuya kwi-100μm kumanzi akrwada, ukunciphisa i-effluent turbidity kunye neCODCr, kwaye ingasetyenziselwa ukulungiswa kwangaphambili kweenkqubo zokucocwa kwamanzi amdaka.Unyango, unyango oluphezulu, lungasetyenziselwa unyango lwe-sludge eseleyo.Ukunyangwa kwe-coagulation kunokususa ngokufanelekileyo ii-microorganisms kunye neebhaktheriya ze-pathogenic emanzini, kunye nokususa ioli e-emulsified, i-chroma, i-ion yensimbi enzima kunye nezinye izinto ezingcolileyo kwi-lindle.Izinga lokususwa kwe-phosphorus equlethwe kugutyulo linokuba phezulu ukuya kuma-90% xa i-coagulation sedimentation isetyenziselwa ukunyanga i-phosphorus.~95%, yeyona ndlela inexabiso eliphantsi nesebenzayo yokususa iphosphorus.
Kwinkqubo yokucocwa kwamanzi amdaka, ezinye ii-agent ziya kusetyenziswa.Namhlanje, iPAM Manufacturerwazisa enye kuphela kuzo.Usayaqonda?Nika ingqalelo kwiYuncang kwaye uphendule ulwazi oluninzi lokunyanga ilindle kuwe!
