Daim ntawv thov ntawm ultrafiltration membrane tshuab hauv kev tiv thaiv ib puag ncig thiab kev kho dej phwj tuaj

Kev siv cov tshuab ultrafiltration membrane hauv kev kho dej haus

Nrog rau kev nce qib ntawm cov txheej txheem hauv nroog tsis tu ncua, cov pej xeem hauv nroog tau dhau los ua ntau thiab ntau dua, cov peev txheej hauv nroog thiab cov dej hauv tsev tau maj mam dhau los ua ib qho laj thawj tseem ceeb rau kev txwv kev loj hlob hauv nroog. Nrog rau kev nce ntxiv ntawm cov pej xeem hauv nroog, kev siv dej txhua hnub hauv lub nroog txuas ntxiv nce ntxiv, thiab cov dej khib nyiab txhua hnub ntawm lub nroog kuj qhia txog kev loj hlob tsis tu ncua. Yog li ntawd, yuav ua li cas txhawm rau txhim kho kev siv cov khoom siv dej hauv nroog thiab txo cov pa phem ntawm cov pov tseg thiab cov dej ntws tau dhau los ua qhov teeb meem tseem ceeb uas yuav tsum tau daws sai. Tsis tas li ntawd, cov peev txheej dej tshiab tsis tshua muaj tsawg thiab tib neeg qhov kev thov rau dej purity tau nce siab dua. Nws yog ib qho tsim nyog yuav tsum xav kom cov ntsiab lus ntawm cov khoom tsis zoo hauv cov khoom siv dej, uas yog, impurities, qis dua, uas ua rau muaj kev xav tau ntau dua rau kev lim dej huv thiab kev siv thev naus laus zis. Ultrafiltration membrane tshuab muaj cov yam ntxwv ntawm physicochemical thiab kev sib cais, kub tsis kam thiab tshuaj tsis kam, thiab pH ruaj khov. Yog li ntawd, nws muaj qhov tshwj xeeb ntawm daim ntawv thov zoo hauv kev kho dej hauv nroog, uas tuaj yeem tshem tawm cov organic tshuaj, tshem tawm cov khoom tsis zoo hauv cov dej haus, thiab ntxiv kom muaj kev nyab xeeb ntawm cov dej haus hauv nroog.

Daim ntawv thov ntawm ultrafiltration membrane tshuab hauv seawater desalination

Lub ntiaj teb cov dej tshiab tsis tshua muaj, tab sis cov peev txheej dej npog txog 71% ntawm lub ntiaj teb tag nrho, uas yog, lub ntiaj teb cov dej hiav txwv siv tsis tau muaj nplua nuj heev. Yog li ntawd, desalination yog ib qho kev ntsuas tseem ceeb los daws qhov tsis txaus ntawm tib neeg cov dej tshiab. Cov txheej txheem ntawm seawater desalination yog txheej txheem nyuaj thiab ntev. Nws yog ib qho kev tshawb nrhiav mus sij hawm ntev los ua kom huv cov dej hiav txwv uas tsis tuaj yeem siv ncaj qha mus rau hauv cov dej tshiab uas tuaj yeem siv ncaj qha. Nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, seawater desalination tshuab tau maj mam loj hlob thiab txhim kho. Piv txwv li, kev siv tshuab electro-osmosis tuaj yeem ua tiav ib zaug desalination ntawm seawater, tab sis lub zog noj ntawm seawater desalination yog qhov loj heev. Ultrafiltration membrane tshuab muaj cov yam ntxwv sib cais zoo, uas tuaj yeem tswj tau qhov teeb meem rov qab osmosis hauv cov txheej txheem ntawm seawater desalination, yog li txhim kho kev ua haujlwm ntawm seawater desalination thiab txo lub zog noj seawater desalination. Yog li ntawd, ultrafiltration membrane tshuab muaj dav daim ntawv thov kev cia siab nyob rau hauv yav tom ntej seawater desalination kev kho mob.

Nrog kev txuas ntxiv mus tob zuj zus ntawm cov txheej txheem hauv nroog, kev tso tawm txhua hnub ntawm cov dej phwj tuaj hauv nroog tau nce zuj zus. Yuav ua li cas rov qab siv cov dej phwj hauv nroog yog qhov teeb meem ceev uas yuav tsum tau daws. Raws li peb txhua tus paub, cov dej phwj hauv nroog tsis yog tsuas yog tso tawm ntau ntau xwb, tab sis kuj tseem muaj cov khoom muaj roj, cov organic teeb meem thiab ntau cov kab mob pathogenic hauv lub cev dej, uas ua rau muaj kev hem thawj loj rau thaj chaw ib puag ncig ecological thiab kev noj qab haus huv ntawm cov neeg nyob hauv. Yog hais tias ib tug loj npaum li cas ntawm cov dej phwj hauv tsev yog ncaj qha tawm mus rau hauv lub ecological ib puag ncig, nws yuav ua phem rau lub ecological ib puag ncig nyob ib ncig ntawm lub nroog, yog li ntawd nws yuav tsum tau tso tawm tom qab kev kho dej phwj. Ultrafiltration membrane tshuab muaj zog physicochemical thiab kev sib cais cov yam ntxwv, thiab tuaj yeem cais cov organic thiab cov kab mob hauv dej. Lub tshuab ultrafiltration membrane yog siv los lim tag nrho cov phosphorus, tag nrho cov nitrogen, chloride ions, tshuaj oxygen xav tau, tag nrho cov yaj ions, thiab lwm yam hauv cov dej hauv nroog, kom lawv txhua tus ua tau raws li cov qauv hauv nroog dej.
