In I-Industrial Wastewater Treatment, kuzoba nezinhlayiya ezincane eziningi ezimisiwe emanzini angcolile.Ukuze ususe lezi zinhlayiya futhi wenze amanzi acace futhi asetshenziswe kabusha, kuyadingeka ukusebenzisaIzengezo Zamakhemikhali Zamanzi -Ama-Flocculants (PAM) ukwenza lezi zinhlayiya ezimisiwe Ukungcola kuminyene kube ama-molecule amakhulu futhi kuhlale phansi.
Izinhlayiya ze-colloid emanzini zincane, futhi indawo engaphezulu ifakwe amanzi futhi ishajwe ukuze izinze.Ngemuva kokuthi i-flocculant yengezwe emanzini, i-hydrolyzed ibe yi-colloid ekhokhisiwe kanye nama-ion ayo azungezile ukuze enze ama-micelles anesakhiwo sesendlalelo esiphindwe kabili kagesi.
Indlela yokunyakazisa ngokushesha ngemva kokudosa iyamukelwa ukukhuthaza ithuba kanye nenani lokushayisana phakathi kwezinhlayiya zokungcola kwe-colloidal emanzini kanye nama-micelles akhiwe yi-hydrolysis ye-flocculant.Izinhlayiya zokungcola emanzini kuqala zilahlekelwa ukuzinza kwazo ngaphansi kwesenzo se-flocculant, bese zihlangana zibe yizinhlayiya ezinkulu, bese zihlala phansi noma zintanta phezulu endaweni yokuhlukanisa.
Umkhiqizo we-GT we-velocity gradient G okhiqizwe ngokunyakazisa kanye nesikhathi esinyakazayo sika-T singamela ngokungaqondile ingqikithi yenani lokungqubuzana kwezinhlayiyana kuso sonke isikhathi sokusabela, futhi umphumela wokusabela kokuhlangana ungalawulwa ngokushintsha inani le-GT.Ngokuvamile, inani le-GT lilawulwa phakathi kuka-104 no-105. Uma kucatshangelwa umthelela wokugxiliswa kwezinhlayiyana zokungcola ekungqubuzaneni, inani le-GTC lingasetshenziswa njengepharamitha yokulawula ukuze ibonise umphumela wokuhlangana, lapho u-C umele ukugxiliswa kwenqwaba yezinhlayiya zokungcola indle, futhi kunconywa ukuthi inani le-GTC libe phakathi kwe-100 noma ngaphezulu.
Inqubo yokwenza ukuthi i-flocculant isakaze ngokushesha emanzini futhi ixubane ngokulinganayo nawo wonke amanzi angcolile ibizwa ngokuthi ukuxuba.Izinhlayiya zokungcola emanzini zisebenzisana ne-flocculant, futhi ngokusebenzisa izindlela ezifana nokucindezelwa kwesendlalelo esiphindwe kabili kagesi kanye ne-neutralization kagesi, ukuzinza kulahlekile noma kuncishisiwe, futhi inqubo yokwenza ama-micro flocs ibizwa ngokuthi i-coagulation.Inqubo ye-agglomeration kanye nokwakheka kwama-micro flocs akhula abe ama-flocs amakhulu ngokusebenzisa izindlela ezifana ne-adsorption bridging kanye ne-sediment net capture ngaphansi kokuyaluza kwezinto ezivala amabhuloho nokugeleza kwamanzi kubizwa ngokuthi i-flocculation.Ukuxuba, ukuhlangana kanye ne-flocculation kubizwa ngokuhlanganyela ngokuthi i-coagulation.Inqubo yokuxuba ngokuvamile iqedwa ku-tank yokuxuba, futhi ukuhlangana nokuhamba kwe-flocculation kwenziwa ethangini lokusabela.
Mayelana nokusetshenziswa kweI-Polyacrylamidefuthi flocculation yayo, ungaxhumanaUkukhiqiza Amakhemikhali Amanziukufunda okwengeziwe
