Qhov Tseem Ceeb Qhov txawv - Coagulation vs Flocculation hauv Kev Kho Dej
Kev kho dej yog ib qho tseem ceeb uas muaj ntau yam sib txawv. Txij li thaum kev kho dej yog ib txoj kev rhiab heev thiab tseem ceeb nws yuav tsum muaj cov txheej txheem ntawm lub cev thiab tshuaj. Restoration ntawm dej zoo yog paub tseeb thaum lub sij hawm kho dej. Coagulation thiab flocculation cov kauj ruam yog ib qho tseem ceeb hauv cov ntsiab lus ntawm kev kho dej vim nws tso cai rau kev sib cais ntawm cov khoom uas raug tshem tawm hauv dej kom zoo. Hauv kev coagulation, cov txheej txheem suav nrog kev siv cov coagulant uas muaj peev xwm ua kom tsis muaj zog ntawm cov khoom siv uas tsis muaj teeb meem thaum flocculation cuam tshuam nrog cov txheej txheem destabilization zoo sib xws uas tau ua tiav los ntawm kev sib xyaw ntawm lub cev thiab los ntawm kev ntxiv cov organic polymers. Qhov sib txawv tseem ceeb ntawm coagulation thiab flocculation hauv kev kho dej yog tias cov coagulation yog cov txheej txheem tshuaj thaum flocculation yog lub cev txheej txheem.
Coagulation yog dab tsi?
Coagulation, hauv cov ntsiab lus yooj yim, yog hu ua curdling lossis clotting. Hauv cov tshuaj lom neeg, nws tuaj yeem piav qhia raws li tus txheej txheem los ntawm kev ua kom tsis muaj zog ntawm cov khoom uas tsis tau daws. Qhov no yog ib kauj ruam tseem ceeb hauv ntau cov txheej txheem biochemical sib txawv. Txawm li cas los xij, coagulation yog siv feem ntau thaum cov txheej txheem kho dej. Coagulation tuaj yeem ua tiav yooj yim los ntawm kev ntxiv cov coagulant rau nruab nrab. Qhov no ua rau lub clumping ntawm hais. Nyob rau hauv kev hwm rau chemistry ntawm cov txheej txheem no, ntxiv ib coagulant destabilizes particle tus nqi. Qhov no ua tiav los ntawm kev ntxiv cov coagulant uas muaj qhov sib txawv ntawm cov khoom raug tshem tawm.
Qhov no cuam tshuam tus nqi ntawm cov khoom sib txawv uas tsis muaj kev cuam tshuam uas suav nrog av nplaum thiab lwm yam khoom siv hauv cov dej uas ua rau cov dej turbidity. Coagulants muaj xws li inorganic ntsev ntawm txhuas los yog hlau. Piv txwv yog aluminium sulfate, aluminium chloride, alum thiab ferric sulfate. Cov ntsev no muaj peev xwm hydrolyze cov khoom rau insoluble precipitates uas entraps cov khoom ua ke.

Thaum cov coagulants tau ntxiv thiab cov nqi ntawm cov khoom nruab nrab, nws tso cai rau cov khoom sib cuam tshuam nrog ib leeg thiab lo ua ke. Cov khoom sib xyaw ua ke no hu ua microflocs. Tab sis cov khoom no tsis pom ntawm qhov muag liab qab. Cov kauj ruam no yog ua raws li flocculation.
Flocculation yog dab tsi?
Flocculation cuam tshuam nrog kev tsim cov flocs. Qhov no feem ntau yog ua tiav los ntawm cov txheej txheem ntawm lub cev thiab kev siv tshuab uas koom nrog cov coagulated clumps uas twb muaj lawm los koom ua ke. Qhov no tshwm sim nyob rau hauv tsim ntawm loj pawg ntawm flocs uas pib tshwm sim raws li ib tug huab thiab ces hloov mus rau hauv ib tug precipitate. Flocculation yog ib kauj ruam tseem ceeb hauv cov txheej txheem kho dej uas ib txwm ua raws cov kauj ruam coagulation.
Thaum lub sijhawm flocculation txheej txheem, cov tshuaj uas yog coagulated twb yog tov maj mam. Qhov no tso cai rau qhov nce ntawm qhov loj ntawm cov coagulated clumps uas yog submicroscopic microflocs mus rau theem uas lawv tshwm sim raws li pom cov khoom tshem tawm. Yog li ntawd, cov pawg loj lossis cov nag lossis daus loj tuaj yeem yooj yim sib cais thiab tshem tawm ntawm qhov nruab nrab. Cov txheej txheem sib xyaw qeeb ntawm flocculation tso cai rau kev sib cuag ntawm microflocs nrog ib leeg uas ua rau kev sib tsoo ntawm microfloc.
Cov kev sib tsoo no ua rau muaj kev sib txuas ntawm microflocs thiab ua rau tsim cov khoom loj dua uas pom. Thaum sib tov txuas ntxiv, qhov loj ntawm floc maj mam nce. Cov txheej txheem no yog pab los ntawm kev sib ntxiv ntawm cov organic polymers uas muaj qhov hnyav molecular. Cov no kuj raug hu ua coagulant pab. Qhov sib ntxiv ntawm cov organic polymers ua rau muaj kev sib txawv. Qhov no tso cai rau kev txuas thiab ntxiv dag zog rau floc uas ua rau kom qhov hnyav ntawm floc thaum tseem nce tus nqi ntawm kev daws teeb meem.

Flocculation ua tiav thaum lub floc nce mus txog nws qhov zoo tshaj plaws lub zog thiab loj. Qhov no feem ntau yuav siv sij hawm ib teev nyob ntawm qhov loj ntawm qhov nruab nrab. Thaum flocculation tiav lawm, cov dej tsim nyog tau txais kev sib cais.
Dab tsi zoo sib xws ntawm Coagulation thiab Flocculation hauv Kev Kho Dej?
- Coagulation thiab flocculation yog ob kauj ruam tseem ceeb thiab tseem ceeb hauv kev haus dej haus thiab dej khib nyiab.
- Ob txheej txheem koom nrog kev sib koom ua ke ntawm cov khoom sib txawv ua ke.
