Rov qab osmosis (RO) concentrated dej rov siv dua

Rov qab osmosis (RO)concentrated dej rov siv dua

Txawm hais tias nws yog kev npaj cov dej ntshiab lossis cov dej khib nyiab rov qab siv dua, thaum siv cov thev naus laus zis rov qab osmosis (RO), nws yuav tsum tau ua ib feem ntawm cov dej muaj zog. Vim yog lub hauv paus ntsiab lus ntawm kev rov qab osmosis, cov dej concentrated hauv qhov no feem ntau muaj cov yam ntxwv ntawm salinity siab, siab silica, siab organic teeb meem, siab hardness thiab lwm yam. Raws li cov yam ntxwv zoo li no, peb feem ntau yuav tsum xaiv qee qhov kev ntsuas rau cov dej ntshiab raws li qhov xwm txheej tshwj xeeb, txhawm rau kom tsis txhob nkim cov khoom siv dej thiab tau txais lub hom phiaj ntawm kev txo nqi thiab nce kev ua haujlwm.

Ua ntej, cov txheej txheem kev kho dej ntau rau kev npaj dej ntshiab:

① Kev tso tawm ncaj qha rau sab nraud (tag nrho cov paug tawm sab nraud): feem ntau hauv cov khoom siv dej ntshiab me me, cov dej kais dej raws li cov dej nyoos, cov dej concentrated ncaj qha peb theem ntawm paug.

Cov laj thawj tseem ceeb: cov dej tsis zoo yog qhov zoo, cov ntsuas dej muaj zog tuaj yeem ua tau raws li cov qauv tso tawm; Tus nqi ntws yog me me thiab tsis muaj kev lag luam tus nqi ntawm kev siv tshuaj kho mob thib ob (piv nrog tus nqi ntawm cov dej nyoos)

Lus Cim: Qee zaum, cov dej ntshiab tuaj yeem muab sib xyaw nrog cov dej nyoos uas zoo dua qub (txo cov concentration ntawm cov ntsuas tshwj xeeb) kom ua tau raws li cov qauv kev tso tawm tertiary. Lub kaw lus tseem tuaj yeem txo cov concentration ntawm cov dej concentrated los ntawm kev txo tus nqi rov qab.

② Recycling (ib feem sau thiab kev kho mob): feem ntau nyob rau hauv nruab nrab cov khoom siv los yog tej yaam num, system rov qab yuav tsum muaj siab, concentrated dej tom qab pretreatment los yog ROR ntaus ntawv, mus rau hauv lub ntsiab system, recycling, txhim kho tag nrho cov nqi rov qab. Ib qho kev faib ua feem ntawm cov dej concentrated (nrog rau tag nrho cov dej ntshiab) tau sau thiab kho, thiab tsis tuaj yeem tso tawm ncaj qha.

Cov laj thawj tseem ceeb: qhov kev rov qab los ntawm qhov system yog siab, ib txoj kev rov qab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua kom rov zoo tag nrho; Kev tiv thaiv ib puag ncig yuav tsum muaj siab, yuav tsum muaj feem ntau ntawm cov peev txheej dej. Kev rov ua dua tshiab ntawm cov dej concentrated ua rau kom cov ntsev thiab lwm yam ntsuas tsis tu ncua, thiab cov dej muaj zog ruaj khov (super concentrated water) yuav tsum tau tso tawm tsis tu ncua kom ua tiav cov haujlwm ruaj khov. Cov ntsuas ntawm qhov no ntawm cov dej concentrated feem ntau dhau ntawm peb theem kev tso tawm cov qauv thiab yuav tsum tau sau thiab kho.

Concentrated water pretreatment: Raws li plaub tus yam ntxwv ntawm cov dej concentrated, ua ke nrog cov xwm txheej tiag tiag, kev siv tshuab pom, softening thiab lwm yam kev ntsuas tau ua, kom cov dej pre-kho concentrated tuaj yeem ua tau raws li cov qauv dej zoo ntawm cov dej nyoos, nkag mus. lub tank qub (pas dej), thiab rov siv dua.

ROR ntaus ntawv: Tom qab kev kho kom zoo ntawm cov dej ntshiab, cov cuab yeej RO ntxiv yog siv rau kev kho mob, thiab cov dej huv uas tsim tawm (uas yuav tsis ua raws li tus qauv dej zoo ntawm cov dej ntshiab) nkag mus rau hauv lub tank qub rau rov siv dua. Lub super concentrated dej tsim los ntawm ROR ntaus ntawv tsis tuaj yeem tso tawm ncaj qha thiab yuav tsum tau sau thiab kho.

Concentrated water pretreatment: Raws li plaub tus yam ntxwv ntawm cov dej concentrated, ua ke nrog cov xwm txheej tiag tiag, kev siv tshuab pom, softening thiab lwm yam kev ntsuas tau ua, kom cov dej pre-kho concentrated tuaj yeem ua tau raws li cov qauv dej zoo ntawm cov dej nyoos, nkag mus. lub tank qub (pas dej), thiab rov siv dua.

ROR ntaus ntawv: Tom qab kev kho kom zoo ntawm cov dej concentrated, ntxivRO ntaus ntawvyog siv rau kev kho mob, thiab cov dej purified generated (uas tej zaum yuav tsis tau raws li tus qauv dej zoo ntawm cov dej ntshiab) nkag mus rau hauv lub tank qub rau rov siv dua. Cov dej muaj zog heev uas tsim los ntawm ROR cov cuab yeej tsis tuaj yeem tso tawm ncaj qha thiab yuav tsum tau sau thiab kho.

Qhia luv luv txog qhov zoo thiab qhov tsis zoo ntawm txhua txoj kev kho hauv kev kho dej khib nyiab

Cov dej rov qab siv dua: ultrafiltration + thim rov qab osmosis (UF + RO), cov txheej txheem rov qab zoo ntawm 50%, cov dej uas muaj zog ntxiv xav tau kev kho mob ntxiv.

Tsawg kub evaporator: tsis tshua muaj kub lub tshuab nqus tsev kho mob, kev ua haujlwm me me, feem ntau 200L / H-- 3000L / H ua lub peev xwm. Cov neeg ua haujlwm tu, electroplating khib nyiab, txiav cov dej khib nyiab thiab lwm yam khoom siv ua kua khib nyiab, qhov kev ua haujlwm kub yog li 30℃.

MVR evaporator: Kev sib xyaw ua ke ntawm qhov kub thiab txias evaporation thev naus laus zis, kev ua haujlwm nruab nrab, kev ua haujlwm dav dav tshaj 0.5T / H. Feem ntau nyob rau hauv tshuaj, khoom noj, ntawv, tshuaj, seawater desalination thiab lwm yam teb, qhov dav ua hauj lwm kub ntawm 70-90℃.

Multi-effect evaporator: Ib txwm muaj qhov kub thiab txias evaporator, los ntawm kev siv ntau lub zog los txhim kho kev siv hluav taws xob zoo ntawm lub zog, nrog cov evaporator thiab condenser ob feem, qhov system ruaj khov, kev siv zog siab, yuav tsum tau nruab nrog chav kaw lus ( muaj cov khoom siv hluav taws xob sib cais).

Outsourcing kev kho mob: Cov dej khib nyiab sib txawv, thaj av sib txawv, cov nqi kho mob sib txawv, thiab cov nqi tsev ib tuj nyob ntawm ntau pua txog txhiab.

Los ntawm kev xaiv ntau yam ntawm cov txheej txheem saum toj no, nws tuaj yeem siv ib leeg lossis ua ke kom ua tiav lub hom phiaj ntawm kev txo nqi thiab nce kev ua haujlwm.
