Hauv kev kho dej khib nyiab, pH yog qhov tseem ceeb tshaj plaws uas cuam tshuam ncaj qha rau kev ua haujlwm ntawmFlocculants.Kab lus no qhia txog qhov cuam tshuam ntawm pH, alkalinity, kub, impurity particle loj, thiab hom flocculant ntawm flocculation efficiency.
Kev cuam tshuam ntawm pH
Cov pH ntawm cov dej khib nyiab yog ze ze rau kev xaiv, ntau npaum li cas, thiab coagulation-sedimentation efficiency ntawm flocculants.Cov kev tshawb fawb qhia tias thaum pH qis dua 4, coagulation efficiency yog qhov tsis zoo.Qhov no tej zaum yuav yog vim tsis muaj pH stabilizing colloidal hais nyob rau hauv cov dej khib nyiab, ua rau nws nyuaj rau flocculants kom zoo coagulate lawv.Thaum pH nyob nruab nrab ntawm 6.5 thiab 7.5, coagulation efficiency ho txhim kho vim hais tias qhov instability ntawm colloidal hais nyob rau hauv no pH ntau txhim khu kev txiav txim ntawm flocculants.Txawm li cas los xij, thaum pH siab tshaj 8, coagulation efficiency deteriorates ho, tej zaum vim hais tias lub siab pH hloov cov ion tshuav nyiaj li cas nyob rau hauv cov dej khib nyiab, adversely cuam tshuam flocculants.
Thaum pH qis dhau lawm, PAC tsis tuaj yeem tsim cov flocs zoo, thiab cov pab pawg anionic ntawm APAM yuav raug nruab nrab, ua rau nws tsis muaj txiaj ntsig.Thaum pH siab dhau lawm, PAC precipitates sai heev, ua rau cov kev ua haujlwm tsis zoo, thiab CPAM yog nquag hydrolysis thiab ua tsis tau zoo.
Lub luag haujlwm ntawm Alkalinity
Lub alkalinity ntawm dej phwj buffers pH.Thaum cov dej phwj tuaj alkalinity tsis txaus, feem ntau nws yog ib qho tsim nyog yuav tsum tau ntxiv nrog cov tshuaj xws li txiv qaub kom tswj pH stability pab PAC qhov zoo tshaj plaws flocculation nyhuv.Hloov pauv, thaum pH ntawm cov dej siab dhau lawm, cov kua qaub yuav tsum tau muab ntxiv kom qis pH kom tsis muaj zog, ua kom cov txiaj ntsig ntawm flocculants.
Kev cuam tshuam ntawm qhov kub thiab txias
Cov dej khib nyiab kuj yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau kev ua haujlwm ntawm flocculation.Thaum qhov kub thiab txias, cov dej khib nyiab nthuav tawm cov viscosity siab, txo qhov zaus ntawm kev sib tsoo ntawm colloidal hais thiab impurities hauv dej, cuam tshuam kev sib nrig sib adhesion ntawm flocculants.Yog li ntawd, txawm hais tias qhov ntau npaum li cas ntawm flocculants, flocculation tseem qeeb, ua rau cov qauv xoob thiab cov khoom zoo uas nyuaj rau tshem tawm hauv qhov kub thiab txias.
Kev cuam tshuam ntawm impurity Particle loj
Qhov loj thiab kev faib tawm ntawm impurity hais hauv cov dej khib nyiab kuj tseem cuam tshuam rau kev ua haujlwm ntawm flocculation.Cov khoom tsis sib xws lossis ntau qhov me me tuaj yeem ua rau tsis zoo flocculation zoo vim hais tias me me impurity hais feem ntau nyuaj rau aggregate zoo los ntawm flocculants.Hauv cov xwm txheej zoo li no, reflux sedimentation lossis ntxiv qhov tsim nyog ntawm flocculant tuaj yeem txhim kho flocculation zoo.
Kev xaiv ntawm Flocculant Hom
Xaiv qhov tsim nyog hom flocculant yog qhov tseem ceeb rau kev txhim kho cov dej khib nyiab zoo.Ntau hom flocculants, xws li inorganic flocculants, polymer flocculants, thiab activated silica gel, muaj lawv qhov zoo nyob rau hauv ntau lub sijhawm.Piv txwv li, thaum tshem tawm cov khib nyiab hauv cov dej khib nyiab muaj nyob rau hauv daim ntawv colloidal, inorganic flocculants feem ntau siv tau zoo dua.Thaum soj ntsuam nrog cov khoom me me, qhov sib ntxiv ntawm cov khoom siv polymer flocculants lossis activated silica gel li coagulants yuav tsim nyog.Feem ntau, kev sib xyaw ua ke ntawm inorganic thiab polymer flocculants tuaj yeem txhim kho flocculation zoo thiab nthuav dav ntawm daim ntawv thov.
Cov yam ntxwv xws li pH tus nqi, alkalinity, kub, impurity particle loj, thiab flocculant hom dej khib nyiab sib koom ua ke cuam tshuam cov txiaj ntsig ntawm flocculants hauv kev kho dej khib nyiab.Kev nkag siab tob tob thiab kev tswj hwm ntawm cov xwm txheej no yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm ntawm cov dej khib nyiab.Peb yog koj tus neeg muab kev ntseeg siab ntawm cov tshuaj flocculant, nrog rau ntau hom flocculants, xws li PAM, PAC, thiab lwm yam. Ntawm peb lub vev xaib official koj tuaj yeem yooj yim tshawb xyuas peb cov khoom siv ntau yam.Yog tias koj muaj lus nug lossis xav tau kev pab, thov koj xav tiv tauj peb!
