Mosebetsi oa PAC ke ofe tabeng ea ho hloekisa metsi?

Mosebetsi

Ketso ea PAC e finyelloa ka likarolo tse 'ne tsa sehlahisoa sa eona sa hydrolysis se hatelitsoeng, ho se nke lehlakore ha motlakase, ho ts'oara marang-rang, le borokho ba adsorption.

E potlakisa le ho sefa ntho e ka tšelisoang ke oxidizer ho baka COD, ka hona ho fokotsa COD, le pula e nang le li-particulate matter.PAC ke sehlahisoa se bolokehileng, se bolokang tikoloho, le se sebetsang hantle sa ho hloekisa metsi a litšila.Ho ke ke ha feela ka katleho ho fokotsa mahloriso a lintho tse phelang, liminerale le likokoana-hloko ka likhoerekhoere, empa hape ka fokotsa chromaticity le turbidity ea likhoerekhoere, ka katleho fokotsa tšilafalo, ntlafatsa monko oa likhoerekhoere, fokotsa acidity le alkalinity ea likhoerekhoere, e le ho ntlafatsa ka katleho tšilafalo ea likhoerekhoere.PAC ke tlatsetso e sebetsang bakeng sa ho hloekisa likhoerekhoere, e nang le karolo ea bohlokoa ho hloekisa likhoerekhoere.

Litšobotsi

PAC ke inorganic polymer coagulant.E ka senya likaroloana tse emisitsoeng hantle le li-ion tsa colloidal metsing, aggregate, flocculate, coagulate le precipitate ka compression ea double layer, adsorption le motlakase neutralization, adsorption le bridging, le precipitate net catching, joalo-joalo, e le ho fihlela tlhoekiso le phello ea kalafo. Ha e bapisoa le li-coagulants tse ling, PAC e na le melemo e latelang: E ​​na le mefuta e mengata ea lisebelisoa le ho ikamahanya le mefuta e mengata ea metsi.E na le mefuta e mengata e fapaneng ea boleng bo loketseng ba PH (5-9), 'me boleng ba PH le alkalinity ea metsi a hloekisitsoeng li nyane.Ha thempereichara ea metsi e le tlase, e ntse e khona ho boloka boemo ba pula bo tsitsitse.Alkalinity ea eona e phahame ho feta matsoai a mang a aluminium le tšepe, 'me e na le phello e fokolang ea khoholeho ea thepa.

Kopo

PAC ke mofuta o mocha oa macromolecule coagulant e sebetsang hantle haholo.E sebelisoa haholo ka metsi a nooang, tlhoekiso ea metsi a indasteri, ts'ebetso ea likhoerekhoere tsa masepala tse litšila tsa indasteri.Ho ka lebisa ho popeho e potlakileng ea mohlape ka boholo bo boholo le pula e potlakileng.E na le maemo a fapaneng a ho ikamahanya le metsi a mocheso o fapaneng le ho qhibiliha ho hotle.PAC e senya hanyenyane 'me e loketse bakeng sa dosing ea othomathike ebile e loketse ts'ebetso.

Qetello

PAC ke coagulant ea bohlokoa tšimong ea tlhoekiso ea metsi.E na le phello e sebetsang ea tlhoekiso mochesong o tlase, moferefere o tlase le metsi a phahameng a turbidity.Leha ho le joalo, kaha monoma ea eona e sebetsana le lintho tse phelang ho hlahisa lintho tse kotsi bophelong ba batho, ho bohlokoa ho netefatsa bohloeki ba PAC tlhoekisong ea metsi.
