1. Cov txheej txheem piav qhia Cov dej nyoos yog cov dej zoo, nrog cov ntsiab lus tshem tawm siab thiab siab tawv. Txhawm rau ua kom cov dej tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm thim rov qab osmosis inflow, lub tshuab lim tau nruab nrog cov xuab zeb zoo quartz sab hauv kom tshem tawm cov khib nyiab thiab sediment hauv dej. Thiab lwm yam impurities. Ntxiv scale inhibitor system tuaj yeem ntxiv nplai inhibitor txhua lub sijhawm los txo cov kev xav ntawm hardness ion scaling hauv dej thiab tiv thaiv cov qauv dej ntau. Lub tshuab lim dej yog nruab nrog lub tshuab lim dej honeycomb-qhov txhab nrog qhov tseeb ntawm 5 microns txhawm rau tshem tawm cov khoom tawv tawv hauv dej thiab tiv thaiv qhov chaw ntawm daim nyias nyias los ntawm khawb. Cov khoom siv rov qab osmosis yog qhov tseem ceeb desalination ib feem ntawm cov khoom siv. Ib-theem rov qab osmosis tuaj yeem tshem tawm 98% ntawm ntsev ions hauv dej, thiab cov dej ntws tawm ntawm theem ob rov qab osmosis ua tau raws li cov neeg siv khoom xav tau.
2. Mechanical lim ua haujlwm
- Exhaust: Qhib lub valve sab sauv thiab lub sab sauv inlet kom xa dej mus rau hauv lub lim mus rau sab sauv valve rau cov dej tsis tu ncua.
- Kev ntxuav kom zoo: Qhib lub qhov tso dej qis thiab lub qhov dej nkag sab sauv kom cov dej hla ntawm cov txheej lim los ntawm sab saum toj mus rau hauv qab. Lub inlet ntws tus nqi yog 10t / h. Nws yuav siv li 10-20 feeb kom txog thaum cov kua dej ntshiab thiab pob tshab.
- Kev Ua Haujlwm: Qhib lub qhov hluav taws xob dej kom xa dej mus rau cov khoom siv hauv qab.
- Backwashing: Tom qab cov khoom siv tau khiav mus rau ib lub sijhawm, vim yog cov av nyob hauv qab, lim ncuav qab zib yog tsim rau ntawm qhov chaw. Thaum lub siab sib txawv ntawm qhov nkag thiab qhov hluav taws xob ntawm lub lim yog ntau dua 0.05-0.08MPa, rov qab yuav tsum tau ua kom cov dej ntws zoo. Qhib lub qhov dej ntws sab saud, rov qab ntxuav lub valve, hla lub valve, yaug nrog 10t / h ntws, li 20-30 feeb, kom txog thaum cov dej ntshiab. Nco tseg: Tom qab rov qab ntxuav, cov cuab yeej ntxuav tom ntej yuav tsum tau nqa tawm ua ntej nws tuaj yeem muab tso rau hauv kev ua haujlwm.
3. Softener switching cleaning Lub hauv paus ntsiab lus ua haujlwm ntawm lub softener yog ion pauv. Cov yam ntxwv ntawm cov ion exchanger yog cov resin yuav tsum tau regenerated nquag. Ua tib zoo saib cov teeb meem hauv qab no thaum siv:
- Thaum lub hardness ntawm cov dej effluent zoo tshaj tus qauv (hardness yuav tsum ≤0.03mmol / L), nws yuav tsum tau nres thiab regenerated; 2. Txoj kev cationic resin regeneration yog muab cov cob rau hauv dej ntsev li ob teev, cia cov dej ntsev kom qhuav, thiab tom qab ntawd siv. Cov dej huv recoils, koj tuaj yeem siv txuas ntxiv;
4. Ntxiv antiscalant system Lub metering twj tso kua mis thiab lub siab-siab twj tso kua mis pib thiab nres tib lub sij hawm, thiab txav synchronously. Tus nplai inhibitor yog MDC150 tsim hauv Tebchaws Meskas. Qhov ntau npaum li cas ntawm cov nplai inhibitor: Raws li qhov nyuaj ntawm cov dej nyoos, tom qab muab xam, qhov ntau npaum li cas ntawm cov tshuaj tua kab mob yog 3-4 grams ib ton ntawm cov dej nyoos. Kev noj cov dej ntawm qhov system yog 10t / h, thiab qhov ntau npaum li cas hauv ib teev yog 30-40 grams. Kev teeb tsa ntawm cov nplai inhibitor: ntxiv 90 litres dej rau hauv lub tank tshuaj, maj mam ntxiv 10 kg ntawm nplai inhibitor, thiab sib tov zoo. Kho lub metering twj tso kua mis ntau rau qhov sib thooj. Nco tseg: Qhov tsawg kawg nkaus concentration ntawm scale inhibitor yuav tsum tsis pub tsawg tshaj 10%.
5. qhov precision lim Lub precision lim muaj qhov pom tseeb ntawm 5μm. Txhawm rau tswj xyuas qhov tseeb, lub kaw lus tsis muaj cov kav dej rov qab. Cov ntsiab lus lim hauv cov lim dej feem ntau siv sijhawm li 2-3 lub hlis, thiab tuaj yeem txuas ntxiv mus rau 5-6 lub hlis raws li qhov ntim dej kho. Qee zaum txhawm rau tswj cov dej ntws tawm, cov khoom lim tuaj yeem hloov ua ntej.
6. Rov qab osmosis tu Reverse osmosis membrane cov ntsiab lus yog nquag scaling vim lub tsub zuj zuj ntawm impurities nyob rau hauv cov dej rau lub sij hawm ntev, ua rau ib tug txo nyob rau hauv dej ntau lawm thiab ib tug txo nyob rau hauv desalination tus nqi. Lub sijhawm no, cov txheej txheem membrane yuav tsum tau muab tshuaj ntxuav.
Thaum cov cuab yeej muaj ib qho ntawm cov xwm txheej hauv qab no, nws yuav tsum tau ntxuav:
- Cov khoom lag luam dej ntws poob mus rau 10-15% ntawm tus nqi ib txwm nyob hauv ib txwm muaj siab;
- Txhawm rau tswj hwm cov khoom lag luam ib txwm muaj dej ntws, cov khoom noj dej siab tom qab kho qhov kub thiab txias tau nce 10-15%; 3. Cov khoom siv dej zoo tau raug txo los ntawm 10-15%; ntsev permeability tau nce 10-15%; 4. Kev khiav hauj lwm siab tau nce 10- 15%. 15% yog '; 5. Lub siab sib txawv ntawm RO seem tau nce ntau.
7. Cia txoj kev ntawm daim nyias nyias:
Lub sij hawm luv luv yog tsim rau cov txheej txheem rov qab osmosis uas tau raug kaw rau 5-30 hnub.
Nyob rau lub sijhawm no, cov txheej txheem membrane tseem raug ntsia rau hauv cov hlab ntsha siab ntawm qhov system.
- Tshem tawm qhov rov qab osmosis system nrog dej pub, thiab xyuam xim kom tshem tawm cov pa tawm ntawm qhov system;
- Tom qab cov hlab ntsha siab thiab cov kav dej muaj feem xyuam nrog cov dej, kaw cov qhov cuam tshuam los tiv thaiv cov roj nkag mus rau hauv lub cev;
- Txhua 5 hnub Yaug ib zaug raws li tau piav qhia saum toj no.
Kev tiv thaiv kev tiv thaiv mus ntev
- Ntxuav cov membrane ntsiab hauv qhov system;
- Npaj cov kua sterilizing nrog rov qab osmosis ua dej, thiab yaug lub rov qab osmosis system nrog cov kua sterilizing;
- Tom qab sau cov txheej txheem rov qab osmosis nrog cov kua sterilizing, kaw cov valve uas cuam tshuam kom cov kua ua kom tsis muaj menyuam hauv lub cev. Lub sijhawm no, xyuas kom meej tias lub kaw lus tau sau tag nrho;
- Yog tias qhov ntsuas kub ntawm lub cev qis dua 27 degrees, nws yuav tsum tau ua nrog cov kua ua kom tsis muaj menyuam tshiab txhua 30 hnub; Yog tias qhov kub siab tshaj 27 degrees, nws yuav tsum tau ua txhua 30 hnub. Hloov cov tshuaj sterilizing txhua 15 hnub;
- Ua ntej rov qab osmosis system rov qab siv dua, yaug lub kaw lus nrog cov dej tsis tshua muaj siab rau ib teev, thiab tom qab ntawd yaug lub kaw lus nrog cov dej siab siab rau 5-10 feeb; Txawm hais tias tsis muaj qhov tsis tshua muaj siab los yog lub zog siab, lub kaw lus cov khoom siv dej Txhua qhov dej ntws yuav tsum qhib tag nrho. Ua ntej lub kaw lus rov ua haujlwm li qub, xyuas thiab paub meej tias cov khoom siv dej tsis muaj cov tshuaj fungicides
