1.} ultrourtration tu tej yam
Thaum lub sijhawm ua haujlwm ntawm ultrafiltration system, nws yuav cuam tshuam los ntawm ntau yam kuab paug hauv lub cev muaj zog, yog li ua rau muaj kuab paug, yog ua rau cov pa phem, thiab inorganic scale .
Lub hom phiaj ntawm pretreatment yog kom txo cov tshuaj no uas ua rau muaj kev ua haujlwm ultrafiltration lwm yam .
Tom qab ultrafiltration membrane system yog kuab paug, muaj kev ua yeeb yam zoo tshaj plaws yog: nce transmerized ntawm dej zoo .
Tshuaj Tu yog txhais tau tias kev daws cov kuab lom ntxhua khaub ncaws kom tiav rau kev xaiv tshuaj lom neeg ua ntej, nws yog li ntawd, nws yuav tsum tau xaiv cov pa phem ntxiv rau cov tshuaj lom neeg uas tsim nyog siv tshuaj lom neeg tsim nyog thiab reagents .
Lub sijhawm tu yog qhov ua tau zoo rov qab ntawm ultrafiltration system Cheebtsam ntawm ultrafiltration membrane Cheebtsam yog li nram no:
(1) Tus qauv transmembrane siab qhov sib txawv nce los ntawm 1 bar;
(2) Cov qauv dej ua rau cov khoom tau tsawg dua li 25%;
(3) Lub transmembrane siab qhov sib txawv nce mus rau 2 bar;
(4) Kev tu huv si yuav tsum tau ua tsawg kawg ib xyoos ib zaug, txwv tsis pub ua kom pom kev ua haujlwm ntawm membrane feem yuav txo qis .
2.}}}} tu txoj kev
Tshuaj Tu yog qhov ua tau zoo rau tshem tawm cov angurants thiab txo cov pa roj ntsha uas txuas nrog thiab txo cov kev ua haujlwm hollwmic
(1) Qhib kev ntxuav cov tshuaj ntxuav kom zoo, thiab tom qab ntawd qhib cov tshuaj tu tshuaj tu tshuaj Inlet Valve.
(2) Pib lub twj tso kua mis tu kom pib siv tshuaj ntxuav membrane, thiab tom qab ntawd qhib cov tshuaj lom neeg tu kom dhau los ntawm daim nyias nyias.
(3) Cig raws li lub sijhawm ntawm .
(4) nres cov tshuaj ntxuav cov twj tso kua mis .
(5) Daj cov tshuaj tu thiab tom qab ntawd yaug cov kav dej thiab cov membbrrane txawv nrog lim dej {}}
(6) Ntxiv rau citric acid, hydrochloric acid (siab tshaj plaws ntawm 1}} 0 mol / l) thiab oxalic acid (siab tshaj plaws 1.0 wt%) kuj tseem siv tau.
Saib xyuas cov hom tshwj xeeb, kev xav thiab ncig xyuas cov tshuaj tiv thaiv tshuaj lom neeg tej zaum yuav raug puas tsuaj lossis tsis muaj kev puas tsuaj lossis lub neej ua kom luv.
Txhawm rau kom tau txais cov nyhuv huv, kev tu kom sov yuav tsum nyob hauv thaj tsam ntawm 20-40 degree.
Rau cov kev taug kev txaus tus nqi ntawm daim nyias nyias ib ce, xa mus rau daim ntawv nyeem cov phau ntawv qhia ntawm txhua qhov chaw tsim khoom .
