Li-flocculants tsa Polyacrylamide li sebetsa hantle haholo ho hloekisoa ha litšila le likhoerekhoere. Bareki ba bang ba tlaleha hore polyacrylamide pam e sebelisitsoeng ho ntša metsi a litšila e tla kopana le mathata a joalo le a mang. Kajeno, ke tla sekaseka mathata a 'maloa a tloaelehileng bakeng sa motho e mong le e mong. :
1. Phello ea flocculation ea polyacrylamide ha e ntle, 'me ke lebaka lefe le etsang hore e se ke ea hatelloa ka har'a seretse? Haeba phello ea flocculation ha e ntle, re tlameha ho qala ho felisa mathata a boleng ba sehlahisoa sa flocculant ka boeona, hore na cationic polyacrylamide e kopana le ionic molek'hule ea boima ba limolek'hule, le phello ea sludge dewatering ea sehlahisoa se sa kopane le maemo Ho hang ha ho molemo. . Tabeng ena, ho nkela PAM sebaka ka boemo bo loketseng ba ion ho ka rarolla bothata.
2. Ke lokela ho etsa'ng haeba palo ea polyacrylamide e kholo haholo?
Chelete e kholo e bolela hore index ea sehlahisoa ha ea lekana, 'me ho na le lekhalo pakeng tsa li-index tse hlokahalang bakeng sa polyacrylamide le sludge flocculation. Ka nako ena, o hloka ho khetha mofuta hape, khetha mofuta o nepahetseng oa PAM le palo ea tlatsetso ho leka, 'me u fumane tšebeliso ea chelete e ngata. litšenyehelo. Ka kakaretso, ho kgothaletswa hore motsoako o qhibilihisitsoeng oa polyacrylamide ke sekete ho isa ho tse likete tse peli, 'me khetho e nyenyane ea teko e etsoa ho ea ka mahloriso ana,' me liphello tse fumanoeng li utloahala haholoanyane.
3.Ke lokela ho etsa'ng haeba viscosity ea sludge ka mor'a ho sebelisa polyacrylamide ka sludge dewatering e phahame?
Boemo bona bo bakoa ke ho eketsoa ho feteletseng ha polyacrylamide kapa sehlahisoa se sa lokelang le seretse. Haeba viscosity ea sludge e fokotseha ka mor'a ho fokotsa palo ea tlatsetso, joale ke bothata ba palo ea tlatsetso. Haeba chelete ea tlatsetso e fokotsehile, phello ha e finyelloe 'me seretse se ke ke sa hatelloa, joale ke bothata ba khetho ea sehlahisoa.
4. Polyacrylamide e eketsoa ho seretse, 'me metsi a kaka ea seretse se latelang a phahame haholo, ke lokela ho etsa'ng haeba kuku ea seretse e sa ome ka ho lekaneng?
Tabeng ena, qala ka ho hlahloba lisebelisoa tsa dehydration. Mochini oa lebanta o lokela ho hlahloba hore na ho otlolla ha lesela la filthara ha hoa lekana, ho kenella ha metsi a lesela la filthara le hore na lesela la filthara le hloka ho nkeloa sebaka; mochine oa khatiso oa poleiti le foreimi o hloka ho hlahloba hore na nako ea khatello ea filthara e lekane, Hore na khatello ea filthara e loketse; centrifuge e hloka ho hlahloba hore na khetho ea moemeli oa dehydrating e nepahetse. Thepa ea stacked screw le decanter dehydration e shebana le ho hlahloba hore na boima ba limolek'hule tsa polyacrylamide bo phahame haholo, mme lihlahisoa tse nang le viscosity e phahameng haholo ha li lumelle ho hatella seretse!
Ho ntse ho e-na le mathata a mangata a tloaelehileng a polyacrylamide tabeng ea ho ntša metsi a litšila. Tse ka holimo ke mathata le litharollo tse atileng haholo tse akaretsoang ka palo e kholo ea debugging sebakeng sa marang-rang. Haeba u na le lipotso mabapi le cationic Polyacrylamide sludge tobetsa kapa sedimentation, kaofela O ka romela lengolo-tsoibila ho rona, a re buisaneng ka tšebeliso ea polyacrylamide ka dewatering ea seretse!
