In Industrial Wastewater Treatment, pachava nezvakawanda zvakaturikwa zvimedu zvidiki mumvura yetsvina.Kubvisa zvimedu izvi uye kuita kuti mvura ijeke uye ishandiswe zvakare, inofanirwa kushandisaMvura Yemakemikari Additives -Flocculants (PAM) kuita zvidimbu zvakaturikwa izvi Zvitsvina zvidzikame kuita mamorekuru makuru uye agadzikane.
Iyo colloid particles mumvura idiki, uye pamusoro payo ine hydrated uye inochajiswa kuti igadzikane.Mushure mekunge iyo flocculant yawedzerwa kumvura, inoiswa hydrolyzed kuita colloid yakachajiwa uye maion ayo akatenderedza kuita micelles nemagetsi kaviri layer.
Iyo nzira yekukurumidza kusimudzira mushure mekuita dosing inogamuchirwa kusimudzira mukana uye nhamba yekudhumhana pakati peiyo colloidal tsvina particles mumvura uye micelles inoumbwa ne hydrolysis ye flocculant.Zvimedu zvisina kuchena zviri mumvura zvinotanga kurasikirwa nekugadzikana pasi pechiito cheiyo flocculant, yobva yabatana muzvikamu zvakakura, uye yobva yagara pasi kana kuyangarara kumusoro munzvimbo yekuparadzanisa.
Chigadzirwa GT chevelocity gradient G inogadzirwa nekukurudzira uye nguva inosimudzira T inogona kumiririra zvisina kunanga huwandu hwese hwekudhumhana kwechikamu panguva yese yekuita, uye iyo coagulation reaction mhedzisiro inogona kudzorwa nekuchinja kukosha kweGT.Kazhinji, kukosha kweGT kunodzorwa pakati pe104 ne105. Tichifunga nezvesimba rekusachena kwechikamu chechikamu pakudhumhana, iyo GTC kukosha inogona kushandiswa seyekudzora parameter kuratidza coagulation mhedzisiro, apo C inomiririra kuwanda kwehuwandu hwekusachena zvidimbu mu. iyo tsvina, uye zvinokurudzirwa kuti kukosha kweGTC kuve pakati pe100 kana zvakadaro.
Iyo nzira yekukurudzira iyo flocculant kuti ipararire nekukurumidza mumvura uye kusanganisa zvakaenzana nemvura yese yetsvina inonzi kusanganisa.Izvo zvimedu zvisina kuchena zviri mumvura zvinopindirana ne flocculant, uye kuburikidza nemaitiro akadai sekumanikidza kwemagetsi kaviri layer uye magetsi neutralization, kugadzikana kunorasika kana kuderedzwa, uye nzira yekugadzira micro flocs inonzi coagulation.Maitiro ekusangana uye kuumbwa kwemadiki flocs anokura kuita flocs hombe kuburikidza nenzira dzakaita seadsorption bridging uye sediment net kubatwa pasi pekusuduruka kwezvinhu zvekuvharisa uye kuyerera kwemvura kunonzi flocculation.Kusanganisa, coagulation uye flocculation zvakabatanidzwa zvinonzi coagulation.Iyo yekusanganisa maitiro anowanzo kupedzwa musanganiswa tangi, uye coagulation uye flocculation inoitwa mune reaction tank.
Nezve kushandiswa kwePolyacrylamideuye flocculation yayo, unogona kubata iyoMvura Kugadzirwa Kwemakemikarikudzidza zvakawanda
