Aluminium Sulfate siv hauv cov dej phwj tuaj phosphorus tshem tawm

Aluminium sulfate feem ntau yog siv los ua purifier rau turbid dej.Nws cov nyhuv siv tau zoo heev, vim tias muaj ntau cov dej phwj tuaj nrog cov ntsiab lus phosphorus siab, uas yuav ua rau muaj kuab paug hauv dej.Txhawm rau kom tsis txhob muaj kuab paug, ntau lub lag luam tam sim no Nws yuav siv los tshem tawm phosphorus hauv cov dej phwj tuaj, yog li nws cov txiaj ntsig zoo li cas, cia peb saib cov kev sim hauv qab no.

1. Ntxiv

Ntxiv 25% concentration ntawm kev daws rau cov dej phwj tuaj kho, ntxiv mus tas li li ntawm ib hlis, thiab kuaj cov nyhuv ntawm qhov sib ntxiv, cov phosphorus cov ntsiab lus ntawm cov dej phwj tuaj tsis kho, thiab cov ntsiab lus phosphorus tom qab tsuas yog microbial phosphorus tshem tawm kev kho mob yuav nce 25. % Cov ntsiab lus phosphorus ntawm cov dej tso tawm tom qab kev kho mob ntawm cov tshuaj nrog ib tug siab concentration yog nqa tawm, thiab ib tug series ntawm kev sib piv cov kev ntsuam xyuas tau nqa tawm.Raws li cov txiaj ntsig kev sim, peb tuaj yeem paub tias tsuas yog siv txoj kev microbial los tshem tawm phosphorus hauv cov txheej txheem dej phwj tuaj, cov ntsiab lus phosphorus hauv cov dej kho kuj tseem yuav txo qis vim qhov tshwm sim ntawm hysteresis.Cov ntsiab lus phosphorus siab dua li niaj hnub no, thiab cov nyhuv tshem tawm phosphorus tsis yog qhov tseem ceeb, tab sis ntxiv aluminium sulfate ua cov dej nag tuaj yeem tshem tawm feem ntau ntawm phosphorus hauv cov dej phwj tuaj, ua rau tsis muaj peev xwm tshem tawm cov phosphorus microbial.Nws tuaj yeem hais tias kev tshem tawm cov tshuaj microbial phosphorus Ib qho muaj zog ntxiv rau txoj kev, nws tuaj yeem hais tias nws yog ib qho tseem ceeb heev hauv kev tshem tawm cov phosphorus dej phwj.Nws tuaj yeem tshem tawm cov phosphorus sai sai hauv lub sijhawm luv luv, thiab nws daws cov teeb meem tom qab ntawm txoj kev microbial.

2. Txiav txim siab qhov concentration ntawm cov tshuaj

Txhawm rau txiav txim siab qhov tsim nyog concentration ntawm cov tshuaj raws li phosphorus precipitating tus neeg sawv cev, peb tau ua cov kev sim thiab kev sib piv ntawm cov nag lossis daus los ntawm 15% concentration tov, 25% concentration tov, thiab 30% concentration tov.Nws tuaj yeem xaus lus tias kev daws ntawm 15% concentration Kev kho cov dej phwj tuaj nrog cov ntsiab lus phosphorus siab yog qee zaum tsis pom tseeb, tab sis kev daws teeb meem nrog 25% tuaj yeem tshem tawm feem ntau ntawm cov phosphorus hauv cov kav dej, thiab kev ua haujlwm ntawm kev daws nrog ib qho concentration ntawm 30% yog qhov pib zoo ib yam li ntawm 25%, yog li xaiv 25% % concentration daws yog tsim nyog rau phosphorus tshem tawm precipitant.

3. Kev lees paub ntawm phosphorus tshem tawm stability

Txhawm rau ua pov thawj tias nws cov phosphorus tshem tawm cov nyhuv yog qhov ruaj khov, peb tau ntxiv 25% kev daws rau cov kav dej phwj tuaj kuaj cov phosphorus tshem tawm cov nyhuv ntev.Thaum kho, cov nyhuv tshem tawm phosphorus yog qhov tseem ceeb thiab ruaj khov dua.Kev saib xyuas mus sij hawm ntev ntawm cov ntsiab lus phosphorus hauv cov dej uas raug ntes thiab tso tawm tag nrho ua raws li lub teb chaws theem nrab cov dej phwj tuaj tawm tus qauv, thiab nws yog qhov zoo heev los siv rau kev tshem tawm phosphorus.

Hauv cov kev sim saum toj no, peb tuaj yeem pom tias cov txiaj ntsig ntawm kev kho dej phwj zoo tib yam yog qhov tsis zoo, thiab cov txiaj ntsig ntawm kev siv txhuas sulfate los kho phosphorus hauv cov dej phwj tuaj yog qhov zoo heev, tab sis kev ruaj ntseg zoo heev, thiab txoj kev kho mob kuj yooj yim heev. .
