Daim ntawv thov ntawm ultrafiltration hauv purification ntawm tsoos suav tshuaj
Lub pretreatment ntawm cov tshuaj ua kua yog ib tug tseem ceeb txheej txheem ua ntej lub membrane sib cais cov khoom ntawm tsoos suav tshuaj. Vim hais tias cov extract ntawm tsoos suav tshuaj feem ntau muaj ntau cov khib nyiab thiab impurities nrog siab txheeb ze molecular hnyav, raws li zoo raws li colloids uas yog ib qho yooj yim ua rau membrane muaj kuab paug, ncaj qha ultrafiltration sib cais ntawm cov tshuaj tov yuav ua rau daim nyias nyias thiab txo cov kev pab cuam lub neej. daim nyias nyias. Yog li ntawd, cov tshuaj npaj yuav tsum tau pretreated ua ntej ultrafiltration. Cov txheej txheem kev kho mob feem ntau yog: ua ntej, kev sib cais centrifugal thiab flocculation sedimentation yog siv los tshem tawm cov khib nyiab loj xws li cov khoom tsis huv, thiab tom qab ntawd microfiltration yog siv los tshem tawm cov kab mob, colloids thiab lwm yam khoom. Vim muaj cov ntsiab lus siab ntawm colloid thiab lwm yam viscous tshuaj nyob rau hauv cov tshuaj suav tshuaj, daim nyias nyias muaj kuab heev. Yog li ntawd, Zui nws yog qhov zoo dua los siv cov ntaub ntawv membrane nrog fouling tsis kam, xws li polyacrylonitrile, sulfonated polysulfone membrane, thiab lwm yam.
Extraction zoo ib feem (ib feem) ntawm tsoos suav tshuaj
Cov khoom ntawm cov tshuaj suav tshuaj yog qhov nyuaj, thiab muaj qee qhov sib txawv ntawm qhov hnyav molecular ntawm txhua yam. Yog tias cov khoom siv ultrafiltration membrane uas tsim nyog qhov pore loj raug xaiv, cov khoom no tuaj yeem sib cais raws li qhov loj me me los ntawm kev tshuaj ntsuam xyuas ntawm daim nyias nyias. Xav txog cov khoom siv hauv paus ntawm kev sib cais, lub hom phiaj ntawm kev sib cais thiab cov khoom siv tuaj yeem siv rau kev sib cais, daim ntawv no tham txog cov teeb meem kev tshawb fawb thiab kev ua haujlwm ntawm kev sib cais ntawm cov txheej txheem ntawm cov tshuaj suav tshuaj, thiab muab tso rau pem hauv ntej tus txheej txheem tsim qauv ntawm daim nyias nyias nyias. technology ntawm tsoos suav tshuaj thiab lub tswv yim ntawm membrane pollution tiv thaiv thiab tswj.
Nyob rau hauv xyoo tas los no, muaj ntau cov lus ceeb toom txog kev kho mob ntawm cov tshuaj suav tshuaj suav tshuaj los ntawm ultrafiltration technology. Kev sib xyaw ntawm ultrafiltration thev naus laus zis thiab kev kho tshuaj suav tshuaj suav tshuaj yog qhov tsim nyog los txhim kho qhov zoo ntawm cov tshuaj suav tshuaj npaj thiab txhawb kev hloov kho tshiab ntawm cov tshuaj suav tshuaj. Cov haujlwm tshawb fawb tshwj xeeb tuaj yeem muab faib ua peb yam: (1) tshawb nrhiav daim ntawv thov ntawm ultrafiltration hauv kev rho tawm cov khoom zoo ntawm cov tshuaj suav tshuaj [8-10]; (2) Kawm txog cov txheej txheem thev naus laus zis ntawm ultrafiltration hauv kev kho cov tshuaj suav tshuaj suav tshuaj [11]; (3) Industrialization ntawm ultrafiltration txheej txheem thiab nws cov teeb meem cuam tshuam. Cov txheej txheem ultrafiltration ntawm xya tus neeg sawv cev ntawm cov tshuaj suav tshuaj (Danshen Decoction, simiaoyong'an decoction, Huanglian Jiedu Decoction, ginseng Shengmai Decoction, Lizhong decoction, Astragalus Decoction thiab leech Decoction) tau kawm los ntawm kev siv polyacrylonitrile membrane nrog cuam tshuam tus nqi ntawm 10000um. Nws tau pom tias qhov kev hloov pauv ntawm cov txheeb ze flux ntawm xya lub tshuab tau zoo ib yam, thiab Danshen Decoction, simiaoyong'an decoction, Huanglian Jiedu Decoction Cov kev rov qab los ntawm cov khoom nquag hauv plaub lub tshuab ntawm Lizhong Decoction tau ntau dua 60 feem pua, uas. tau ntau dua qhov ntawd tom qab dej cawv nag lossis daus. Cov kua qaub mucopolysaccharide ntawm Stichopus japonicus tau purified los ntawm ultrafiltration membrane nrog ib qho hnyav molecular ntawm 8000um, thiab qhov tsis kam lees yog 97.2 feem pua. Qhov hnyav molecular ntawm Ginkgo biloba flavone (SPE) yog purified los ntawm ultrafiltration los ntawm crude membrane ntawm Ginkgo biloba (SPE) mus rau 2.39 feem pua ntawm polyether sulfone (GBS).
