Lub luag haujlwm ntawm calcium chloride hauv kev kho dej phwj

Ua ntej, txoj kev dej phwj tuaj kev kho mob yog suav nrog kev kho mob lub cev thiab tshuaj lom neeg. Lub cev lub cev yog siv ntau yam ntawm cov roj lim nrog cov qauv kev sib txawv, yog li cov qauv ntawm cov khoom siv lim, yog li qhov loj dua hauv cov khoom siv tsis tuaj yeem dhau mus, thiab tom qab ntawd tau txais cov dej huv ntxiv. Ib qho ntxiv, lub cev txoj kev kuj tseem suav nrog cov txheej txheem nag dej, uas yog kom cia cov dej ntws tawm ntawm sab nraud, lossis cov kev ua kom loj dua nrog cov ua kom loj dua rau hauv qab, thiab tom qab ntawd tau txais. Cov qauv siv tshuaj yog siv tshuaj rau ntau yam tshuaj tsis zoo rau cov dej hauv dej, lossis cov khoom siv tshuaj lom neeg nyob hauv dej, koj tuaj yeem siv txoj kev lim dej kom tshem tawm cov impurities.

Calcium chloride, muaj tshuaj lom neeg siv hauv kev kho dej phwj tuaj, yog cov ntsev nyob hauv cov ntsev tsim ntawm cov tshuaj chlorine thiab calcium, yog cov ionic haride. Chloride ions muaj peev xwm sterilize dej, tua cov kab mob phom sij, thiab txo cov kab mob uas tsis zoo. Calcium ions tuaj yeem hloov cov khoom lag luam hlau, cais thiab tshem tawm cov hlau hnyav, thiab ua kom muaj kev tiv thaiv kab mob calcium hnyav, uas muaj cov txiaj ntsig zoo thiab muaj txiaj ntsig zoo.

Hauv qab no yog los qhia lub luag haujlwm tshwj xeeb ntawm calcium chloride hauv dej phwj tuaj kho:

1. Calloride yaj hauv dej tom qab chloride ion muaj cov nyhuv ntawm kom tsis muaj menyuam.

2. Calcium ions tuaj yeem hloov cov khoom lag luam hlau hauv lub effluent, tshwj xeeb tshaj yog nyob rau hauv kev kho dej kom muaj hlau hlau. Txhawm rau txo cov kev puas tsuaj ntawm cov tshuaj lom neeg lom zem rau cov khoom siv roj ntsha, calcium tshuaj kom tshem tawm cov tshuaj lom thiab cov tshuaj phem, uas ua si lub luag haujlwm tseem ceeb. Yog tias cov tshuaj no tau siv nyob rau hauv seem effluent, chloride ions ua si ntawm lub luag haujlwm txaws. Calcium ions tsim calcium hydroxide precipipitated thiab tau raug tshem tawm los ntawm nag lossis daus.

3. P Neutralization thiab pre-txoj cai ntawm acidic dej phwj yeeb nkab hlau los txuas lub neej pabcuam ntawm cov cab cab no.

Txheej txheem kev thov tshwj xeeb: Tom qab cov dej khib nyiab tau sau rau hauv lub tank tswj tank, cov dej khib nyiab tau tsa mus rau lub tshuab nqus dej ua ke los ntawm kev nqa cov twj tso kua mis. Lub TOWMULULULATIVULULULULATIVULATIC tau muab faib ua ob qho txheej txheem ntawm cov kev sib xyaw qeeb thiab ua kom sib xyaw nrawm nrawm, tag nrho ntawm plaub theem ntawm cov tshuaj tiv thaiv. Hauv kev sib xyaw ceev ceev tank, sodium hydroxide tau ntxiv rau cov kua dej dosing kom haum lub phua rau hauv lub tank rau 8, thiab caldicle polyaluminium chloride thiab calcium chloride ntxiv rau tib lub sijhawm. By adding flocculant polyacrylamide in the slow mixing tank, the formed calcium chloride particles coagulate with each other to form larger granular floc; Tom qab flocculation, lub effluent ntws mus rau hauv tenimentation tank, los ntawm kev sib cais ntawm cov khoom ua kua ntawm cov kua tawb, thiab tom qab ntawd ntws mus rau hauv cov kev sib cais theem nrab. Tom qab sib cais theem nrab thiab dej nag los ntawm cov hnab lim dej tom qab dhau los ntawm cov roj ntsha hauv qab ntawm cov pa roj ntsha ntawm cov roj ntsha ntawm cov roj ntsha ntawm cov roj ntsha ua ke, thiab tom qab ntawd tus nqi b f f fluoride, thiab tom qab ntawd tus nqi b f f fluoride, thiab tom qab ntawd tus nqi b f f fluoride, thiab tom qab ntawd tus nqi py tau hloov kho thiab tawm. Cov dej tsis tsim nyog tau tso tawm rau hauv lub thawv txias thiab tom qab kho.
