Polyacrylamide - Lub luag haujlwm ntawm Cov Dej Phwj Flocculants

Yuav kom tso tawm lossis rov siv cov dej phwj tuaj tom qab kho, yuav tsum siv ntau yam tshuaj lom neeg hauv cov txheej txheem kho dej phwj tuaj. Niaj hnub no,Cov neeg muag khoom PAM (Polyacrylamide)yuav qhia koj txog cov flocculants:

Cov khoom ua kom cov dej khovQee zaum kuj hu ua coagulant, nws tuaj yeem siv los ua ib txoj hauv kev los txhawb kev sib cais ntawm cov khoom khov thiab kua, thiab nws tuaj yeem siv rau hauv lub tank thawj zaug, lub tank thib ob, lub tank flotation, kev kho mob thib peb lossis kev kho mob siab heev thiab lwm yam kev sib txuas.

Cov tshuaj flocculants siv los ua ib txoj hauv kev los txhawb kev sib cais cov khoom khov thiab kua hauv kev kho dej phwj tuaj. Lawv tuaj yeem siv los txhawb kev tso dej phwj thawj zaug, kev kho dej phwj tuaj thiab kev tso dej thib ob tom qab cov txheej txheem ua kom cov sludge ua haujlwm, thiab kuj tseem siv tau rau kev kho dej phwj theem peb lossis kev kho dej phwj siab. Thaum siv rau kev kho ua ntej ua kom cov sludge ntau dhau qhuav, cov tshuaj flocculants thiab coagulants ua cov tshuaj kho sludge lossis cov neeg sawv cev dehydrating.

Thaum siv cov tshuaj flocculants ib txwm muaj, txoj kev ntxiv cov tshuaj pab coagulant tuaj yeem siv los txhim kho cov nyhuv flocculation. Piv txwv li, siv cov kua qaub ua kom muaj zog ua cov tshuaj pab coagulant rau cov inorganic flocculants xws li ferrous sulfate thiab aluminium sulfate thiab ntxiv lawv ua ntu zus tuaj yeem ua tiav cov flocculation zoo. Yog li ntawd, hauv cov lus yooj yim, cov inorganic polymer flocculant IPF tau npaj los ntawm kev sib xyaw cov tshuaj pab coagulant thiab cov flocculant thiab tom qab ntawd ntxiv ua ke kom yooj yim rau tus neeg siv ua haujlwm.

Kev kho mob coagulation feem ntau yog muab tso rau pem hauv ntej ntawm qhov chaw sib cais cov khoom khov-kua, thiab ua ke nrog qhov chaw sib cais, nws tuaj yeem tshem tawm cov khoom khov thiab cov khoom colloidal nrog qhov loj me ntawm 1nm txog 100μm hauv cov dej nyoos, txo cov dej khib nyiab turbidity thiab CODCr, thiab tuaj yeem siv rau hauv kev kho ua ntej ntawm cov txheej txheem kho dej phwj tuaj. Kev kho mob, kev kho mob siab heev, kuj tuaj yeem siv rau kev kho cov sludge seem. Kev kho mob coagulation kuj tseem tuaj yeem tshem tawm cov kab mob me me thiab cov kab mob pathogenic hauv dej, thiab tshem tawm cov roj emulsified, chroma, cov hlau hnyav ions thiab lwm yam pa phem hauv cov dej phwj tuaj yeem siab txog 90% thaum coagulation sedimentation siv los kho phosphorus. ~ 95%, yog txoj hauv kev pheej yig tshaj plaws thiab ua haujlwm zoo tshaj plaws ntawm kev tshem tawm phosphorus.

Hauv cov txheej txheem ntawm kev kho dej phwj tuaj, lwm cov neeg sawv cev yuav raug siv. Niaj hnub no, tusChaw Tsim Khoom PAMtsuas yog qhia ib qho ntawm lawv xwb. Koj puas tseem nkag siab? Ua tib zoo mloog Yuncang thiab teb ntau yam kev paub txog kev kho dej phwj rau koj!
