Kev saib xyuas ntawm MBR membrane system Tom qab MBR system tau siv rau lub sijhawm, vim tias cov kab mob sib xyaw ua ke ntawm daim nyias nyias kom ua rau lub siab sib txawv ntawm daim nyias nyias, cov txheej txheem membrane yuav tsum tau muab ntxuav thiab khaws cia. Thawj qhov siab sib txawv ntawm daim nyias nyias yog li ntawm 10KPa, thiab MBR membrane modules tau lim rau ib lub sijhawm. Tom qab ntawd, thaum lub siab sib txawv ntawm daim nyias nyias yog 20 KPa siab tshaj qhov pib theem, nws yog ib qho tsim nyog yuav tau ua tshuaj ntxuav. Thaum qhov sib txawv ntawm qhov sib txawv ntawm transmembrane mus txog 35kPa, kev kho kho yuav tsum tau ua. Thaum lub membrane flux tsis tuaj yeem rov qab los ntawm kev kho dua tshiab, kev tu tshuaj tua kab mob yuav tsum raug txiav txim siab. Kev tu tshuaj hauv online ntawm MBR tuaj yeem ua rau MBR system khiav ruaj khov. Nyob rau tib lub sijhawm, tom qab 2 xyoos, cov dej ntws ntawm cov txheej txheem membrane yog li ntawm 90-95% ntawm thawj thawj lub xeev.
MBR system online tshuaj ntxuav tu cov kauj ruam:Txhawm rau kom ntseeg tau tias cov dej tsim tau zoo ntawm MBR membrane, cov membrane yuav tsum tau ntxuav tsis tu ncua hauv online. Yog tias qhov sib txawv ntawm qhov sib txawv ntawm transmembrane nce mus txog lossis ntau dua 35 kPa, cov nyhuv rov qab yuav cuam tshuam zoo heev. Txoj kev tshuaj xyuas hauv online tau pom zoo yog: kev tu tu ib zaug ib lub lim tiam, kho dua tshiab ib hlis ib zaug, thiab khaws tsawg kawg ib zaug txhua rau lub hlis.
1. Hom thiab zaus ntawm tshuaj ntxuav
Feem ntau siv cov tshuaj ua kua yog sodium hypochlorite, citric acid, thiab oxalic acid daws.
① Kev tu tu: ib zaug ib lub lim tiam, 500 ~ 1500 mg / L sodium hypochlorite aqueous tov, qhov concentration ntawm cov tshuaj yog ua raws li qhov xav tau ntawm engineering;
② Restorative tu: ib hlis ib zaug, 2000-3000 mg/L sodium hypochlorite aqueous tov;
③ Pickling voj voog: ib zaug txhua rau lub hlis lossis raws li cov pa phem tshwj xeeb ntawm daim nyias nyias, 1 mus rau 2% (feem ntau) ntawm citric acid lossis oxalic acid daws.
2. Kev noj tshuaj
Tus nqi ntawm cov tshuaj siv ib square meter ntawm daim nyias nyias cheeb tsam yog 2 mus rau 4 L, ntxiv rau tus nqi yuav tsum tausau lub raj xa tshuaj.
3.Online tshuaj ntxuav cov kauj ruam
① Nres lim thiab aeration: thawj zaug tua lub twj tso kua mis thiab kaw cov dej ntau lawmpneumatic valve rau txoj kev hauv tsev uas yuav tsum tau ntxuav. Tom qab 1 mus rau 2 feeb, kaw lub aeration. Nws yuav tsum tau lees paub rau ntawm qhov chaw tias aeration tau raug kaw tag nrho. Cov dej nkag thiab rov qab ntawm txoj kev hauv tsev kuj raug kaw, thiab tom qab ntawd lub valve ntawm cov kav dej tshuaj tau qhib;
② Ntxiv cov tshuaj tov tshuaj: Nyob rau hauv cov cheeb tsam uas tsis tshua muaj dej kub, koj yuav tsum xav txog cov cua sov tudaws kom tsim nyog. Ua kom qhov kub thiab txias tuaj yeem txhim kho cov nyhuv tu. Qhov pom zoontxuav cov tshuaj kub yog 25 ~ 35degree. Qhib cov kua tshuaj txhaj tshuaj thiab txhaj cov kuatshuaj kho mob; ntxiv cov tshuaj ua kua hauv peb pawg, txhua qhov ntxiv ib feem peb ntawm cov tshuaj. Ntxiv txoj kev: dosing rau 5 feeb nyob rau sab saum toj ntawm daim ntawv thiab so rau 5 feeb; Tom qab ntawd, ua qhov koob thib ob, ntxiv Do cov tshuaj rau 5 feeb thiab sawv ntsug li 5 feeb; ua qhov kev txhaj tshuaj thib peb, ua cov tshuaj rau 5 feeb, thiab tom qab ntawd kaw txoj kev hauv tsev kho mob valve;
③ Tom qab noj tshuaj tiav lawm, cia nws sawv ntsug li 1 mus rau 1.5 teev, thiab tom qab ntawd npliag aerate (tsuas yog aeration tsis muaj.ua dej) tom qab 0.5 mus rau 1 teev, qhib txoj hauv kev rau cov dej ntws thiab rov qab, thiab rov ua kom cov dej ntau lawm rau lub xeev tsis siv neeg.
