Hydraulic cov xwm txheej thiab Alum tsim nyob rau hauv peb theem ntawm cov txheej txheem kev sib cais.
1. Cov txheej txheem hws: Nws yog cov txheej txheem uas cov kua yog txhaj rau hauv lub taub hau lub taub hau thiab cov dej nyoos tau nplua cov paj hauv lub sijhawm luv luv. Nyob rau lub sijhawm no, cov dej dej yuav tsum muaj cov tawv tawv ntau dua, uas yuav tsum muaj cov dej ntws los ua cov dej khov nqaim. Nyob rau hauv beaker sim, nws raug nquahu kom do sai ({1}} rpm) rau} s, feem ntau tsis ntau tshaj 2min.
2. Flocculation Stage: Nws yog cov txheej txheem ntawm Alum kev loj hlob thiab coarsing, uas yuav tsum muaj lub sijhawm muaj kev nyuaj thiab muaj kev nyob zoo ({1}} min). Nyob rau hauv tom qab theem tom qab, muaj ntau tus neeg Alum tuaj yeem pom kom sib sau thiab cov dab dej maj mam los ua cov txheej ntshiab txheej txheej. Lub beaker sim tau muab do ntawm 150 rpm li ntawm 6 feeb, thiab tom qab ntawd nplawm ntawm 60 rpm li 4 feeb kom txog thaum nws raug tshem tawm.
3. Kev sib hais theem: Nws yog qhov teeb tsa kev daws teeb meem ntawm flocculant hauv kev teeb tsa tank, uas yuav tsum tau qeeb dej ntws. Txhawm rau txhim kho kev ua tau zoo, tsim lub raj (phaj) teeb tsa tank yog feem ntau saws (nws yog qhov zoo tshaj plaws kom cais cov nplaim taws los ntawm huab cua flotation). Coob tus ntawm cov coarse alum paj yog thaiv los ntawm cov raj inclined (phaj) phab ntsa thiab muab tso rau hauv qab ntawm lub pas dej. Cov dej sab saud yog cov dej kom meej. Cov kev ntxhibas nyob hauv qab tseem tsis tau hloov pauv hauv cov theem tom qab. Lub beaker sim yuav tsum tau do ntawm 20-30 rpm rau 5 feeb, thiab tom qab ntawd hais daws rau 10 feeb los ntsuas qhov tseem ceeb.
4. Ntxiv rau kev xaiv, feem ntau yog kev xaiv tsim nyog ntawm cov txheej txheej txheej thiab cov kev txwv lim, nws yog qhov tseem ceeb los txhim kho cov dej ua tau zoo.
5. Cov khoom no siv nyob rau hauv kev kho ntawm kev tiv thaiv ib puag ncig thiab kev siv dej nyab xeeb, thiab kev siv txheej txheem yog kwv yees tib yam li ntawm cov dej cog. Cov dej nyoos nrog chroma, cov cim siab thiab lub raum yog qhov zoo heev nrog cov cuam tshuam zoo.
6. Rau cov lag luam siv tshuaj lom neeg sib xyaw ua ke cov qauv, cov khoom qub tsis tas yuav tau hloov kho, thiab cov khoom lag luam tuaj yeem siv tau los ntawm kev ntxiv cov alum dissterving tank.
7. Cov khoom yuav tsum tau muab cia rau hauv ib qhuav, noo-pov thawj thiab qhov chaw pov thawj kub (<80oC, do not damage the package, the product can be stored for a long time).
8. Cov khoom lag luam no yuav tsum tau ua ntej siv, thiab cov khoom tsis muaj zog thiab cov chaw siv tshuaj yuav tsum yog ua los ntawm cov khoom siv corrosion-resistant cov ntaub ntawv.
