In Ukucocwa kwamanzi amdaka kwimizi-mveliso, kuya kubakho amasuntswana amancinci amaninzi amisiweyo kumanzi amdaka.Ukususa ezi ngqungquthela kwaye wenze amanzi acace kwaye asetyenziswe kwakhona, kuyimfuneko ukusebenzisaIzongezo zeMichiza zaManzi -Iiflocculants (PAM) ukwenza la masuntswana amisiweyo Ubumdaka bujiyane bube ziimolekyuli ezinkulu kwaye buhlale phantsi.
Iincinci ze-colloid emanzini zincinci, kwaye umphezulu we-hydrated kwaye uhlawuliswe ukuze uzinze.Emva kokuba i-flocculant ifakwe emanzini, i-hydrolyzed ibe yi-colloid ehlawulisiweyo kunye neeoni zayo ezijikelezayo ukuze zenze i-micelles kunye nesakhiwo sombane esiphindwe kabini.
Indlela yokuvuselela ngokukhawuleza emva kwe-dosing yamkelwe ukukhuthaza ithuba kunye nenani lokungqubana phakathi kweengqungquthela zokungcola kwe-colloidal emanzini kunye ne-micelles eyenziwe yi-hydrolysis ye-flocculant.Iingqungquthela ezingcolileyo emanzini ziqala zilahlekelwa ukuzinza kwazo phantsi kwesenzo se-flocculant, emva koko zidibanise kunye zibe ngamaqhekeza amakhulu, zize zihlale phantsi okanye zijikeleze kwindawo yokwahlula.
Imveliso ye-GT ye-velocity gradient G eveliswa ngokuvuselela kunye nexesha elishukumisayo i-T inokumela ngokungathanga ngqo inani elipheleleyo lokungqubana kwamasuntswana kulo lonke ixesha lokusabela, kunye nesiphumo sokusabela kwe-coagulation sinokulawulwa ngokutshintsha ixabiso le-GT.Ngokuqhelekileyo, ixabiso le-GT lilawulwa phakathi kwe-104 kunye ne-105. Ukuqwalasela impembelelo yoxinzelelo lwe-particle yokungcola kwi-collision, ixabiso le-GTC linokusetyenziswa njengeparamitha yokulawula ukubonakalisa umphumo we-coagulation, apho i-C ibonisa ukuxinwa kobuninzi beengqungquthela zokungcola. amanzi amdaka, kwaye kuyacetyiswa ukuba ixabiso le-GTC libe phakathi kwe-100 okanye njalo.
Inkqubo yokwenza ukuba i-flocculant isasazeke ngokukhawuleza emanzini kwaye idibanise ngokulinganayo kunye nawo onke amanzi amdaka ibizwa ngokuba ngumxube.Iingqungquthela ezingcolileyo emanzini zisebenzisana ne-flocculant, kunye neendlela ezifana nokunyanzeliswa kombane ophindwe kabini kunye nokungathathi hlangothi kombane, ukuzinza kulahlekile okanye kuncitshiswe, kwaye inkqubo yokwenza i-microflocs ibizwa ngokuba yi-coagulation.Inkqubo yeagglomeration kunye nokwakheka kwee-micro flocs ezikhula zibe yiflocs ezinkulu ngokusebenzisa iindlela ezifana ne-adsorption bridging kunye ne-sediment net capture phantsi kokuphazamiseka kwezinto ezivalayo kunye nokuhamba kwamanzi kubizwa ngokuba yi-flocculation.Ukuxuba, ukujija kunye ne-flocculation ngokudibeneyo kuthiwa yi-coagulation.Inkqubo yokuxuba ngokubanzi igqitywe kwi-tank yokuxuba, kwaye i-coagulation kunye ne-flocculation iqhutyelwa kwitanki yokusabela.
Malunga nokusetyenziswa kwePolyacrylamidekunye flocculation yayo, ungaqhagamshelana neUkwenziwa kweMichiza yamanziukufunda ngakumbi
