In Kurapa Mvura Yakasviba Yemaindasitiri, pachava nezvidimbu zvidiki zvakawanda zvakasungirirwa mumvura yakasviba. Kuti ubvise zvidimbu izvi uye kuti mvura ichene uye ishandiswezve, zvakakosha kushandisaZvinowedzerwa zveMakemikari emvura -Flocculants (PAM) kuita kuti zvidimbu izvi zvakasungirirwa. Kusachena kunoungana kuita mamorekuru akakura uye kunogadzikana.
Zvidimbu zvecolloid mumvura zvidiki, uye pamusoro payo panonyoroveswa mvura uye kuchajiwa kuti zvigadzikane. Mushure mekunge flocculant yawedzerwa mumvura, inonyungudutswa kuita colloid yakachajiwa uye maion ayo akaipoteredza kuti igadzire micelles ine chimiro chemagetsi chakapetwa kaviri.
Nzira yekukurunga nekukurumidza mushure mekuyedza inoshandiswa kukurudzira mukana uye huwandu hwekusangana pakati pezvikamu zvisina kuchena zvecolloidal mumvura uye micelles inoumbwa nehydrolysis yeflocculant. Zvikamu zvisina kuchena mumvura zvinotanga zvarasikirwa nekugadzikana kwazvo pasi pekushanda kweflocculant, zvobva zvabatana kuita zvikamu zvikuru, zvobva zvagara pasi kana kukwira muchikamu chekuparadzanisa.
Chigadzirwa cheGT che velocity gradient G chinogadzirwa nekukurunga nenguva yekukurunga T chinogona kuratidza huwandu hwese hwe particle collisions munguva yese yekukurunga, uye coagulation reaction effect inogona kudzorwa nekushandura GT value. Kazhinji, GT value inodzorwa pakati pe104 ne105. Tichifunga nezvesimba re uncleanness particle concentration pakukurunga, GTC value inogona kushandiswa se control parameter kuratidza coagulation effect, apo C inomiririra mass concentration ye uncleanness particles mu sewage, uye zvinokurudzirwa kuti GTC value ive pakati pe100 kana kupfuura.
Maitiro ekuita kuti flocculant ipinde mumvura nekukurumidza uye isanganiswe zvakaenzana nemvura yese yakasviba anonzi kusanganisa. Zvidimbu zvisina kuchena mumvura zvinosangana neflocculant, uye kuburikidza nenzira dzakadai sekudzvanywa kwe electric double layer uye electrical neutralization, kugadzikana kunorasika kana kuderera, uye maitiro ekugadzira micro flocs anonzi coagulation. Maitiro ekubatana uye kuumbwa kwe micro flocs inokura kuita ma flocs makuru kuburikidza nenzira dzakadai se adsorption bridging uye sediment net capture pasi pekumutswa kwezvinhu zvinobatanidza uye kuyerera kwemvura kunonzi flocculation. Kusanganisa, kusanganisa uye kusanganisa zvinonzi coagulation. Maitiro ekubatanidza anowanzoitwa mu mixing tank, uye coagulation uye flocculation zvinoitwa mu reaction tank.
