Anthu ambiri ali ndi kusamvetsetsana pang'ono paza membrane, apa tikufotokozera zamalingaliro olakwika awa, tiyeni tiwone ngati muli nawo!

Kusamvetsetsa 1: Njira yoyeretsera madzi ya ma membrane ndiyovuta kugwira ntchito

Zofunikira zowongolera zokha pamakina ochizira madzi a nembanemba ndizokwera kwambiri kuposa zamachitidwe ochiritsira achilengedwe. Ogwiritsa ntchito ambiri amakhulupirira molakwika kuti njira yochizira madzi ya membrane ndiyovuta kugwira ntchito.

M'malo mwake, kugwiritsa ntchito kachipangizo kamadzi kamene kamakhala kodziwikiratu, ndipo ntchito yoyambira ndi kuyimitsa, madontho ndi kutsuka pa intaneti zonse zimachitika ndi dongosolo la PLC. Itha kukhala yosasamalidwa, kuyang'anira ndi kugawa nthawi zonse pamanja, kukonza ndi kuyeretsa nthawi ndi nthawi ndikofunikira, ndipo kwenikweni palibe antchito owonjezera omwe amafunikira.

Kuyeretsa ndi kukonza kansalu kokhazikika kumatha kuchitika tsiku limodzi la maphunziro, zomwe ndizovuta kwambiri kuposa biochemical system yomwe imafuna luso lapamwamba la ogwira ntchito.

Kusamvetsetsa 2: Ndalama zambiri, sizingakwanitse kugwiritsa ntchito

Anthu ena amaganiza kuti ndalama zogulira kamodzi kokha ndi ndalama zolowa m'malo ndizokwera kwambiri, motero sangakwanitse kugwiritsa ntchito. M'malo mwake, ndikukula mwachangu kwa opanga ma membrane am'nyumba, mtengo wa membrane ukutsika nthawi zonse.

Kugwiritsa ntchito nembanemba ya MBR kumatha kupulumutsa mtengo wa zomangamanga ndi malo, kuchepetsa kuchuluka kwa zinyalala ndi kutayira zinyalala, ndizotsika mtengo ndipo ndi chisankho chabwino. Kwa UF membrane ndi RO system, phindu lazachuma lomwe limabwera chifukwa chobwezeretsanso madzi oyipa ndizochulukirapo kuposa ndalama zomwe zimagwiritsidwa ntchito pazida.

Kusamvetsetsa 3: Membrane ndi yofooka komanso yosavuta kusweka

Chifukwa chosowa chidziwitso, makina a nembanemba omwe amapangidwa ndikupangidwa ndi makampani ena opanga uinjiniya ali ndi vuto la kuthyoka kwa ulusi ndi kuwotcha ma module etc., ndipo ogwiritsa ntchito amakhulupirira molakwika kuti zinthu za nembanemba ndizovuta kuzisamalira. M'malo mwake, vuto limachokera ku kapangidwe kake komanso kachitidwe ka membrane.

Ndi kapangidwe koyenera kachipatala koyambirira komanso chitetezo chachitetezo, nembanemba yapamwamba kwambiri ya PVDF imatha kugwiritsidwa ntchito kwa zaka zopitilira 5, ikagwiritsidwa ntchito limodzi ndi nembanemba ya RO, moyo wautumiki wa nembanemba wa RO utha kukulitsidwa bwino. .

Kusamvetsetsa 4: Mtundu/ kuchuluka kwa nembanemba ndikofunikira kwambiri kuposa kapangidwe ka membrane

Mabizinesi ena akakhazikitsa kachipangizo ka membrane, amalabadira kwambiri zopangidwa kuchokera kunja, ndipo samamvetsetsa kufunikira kwa kapangidwe kake.

Masiku ano, magwiridwe antchito a nembanemba yapanyumba ya ultrafiltration yafika kapena kupitilira mulingo wapamwamba wapadziko lonse lapansi, chi?erengero cha magwiridwe antchito ndichokwera kwambiri kuposa nembanemba zochokera kunja. Muzochitika zenizeni, zovuta zamakina a membrane zimachokera ku kapangidwe ka engineering.

Pamene njira ya UF + RO kapena MBR + RO yakhazikitsidwa, kusagwira bwino ntchito kwa dongosolo la RO nthawi zambiri kumakhudzana ndi malo osakwanira a MBR kapena UF membrane kapena mapangidwe osayenera, zomwe zimapangitsa kuti madzi alowetsedwe kwambiri a RO system. .

Kusamvetsetsa 5: Ukadaulo wa Membrane ndi wamphamvu zonse

Membrane ndondomeko ali ndi makhalidwe otsika turbidity wa utsi, decolorization, desalination ndi kufewetsa, etc. Komabe, pochiza madzi zinyalala mafakitale, nembanemba luso nthawi zambiri ayenera pamodzi ndi chikhalidwe physicochemical ndi biochemical mankhwala njira, kuti bwino kusewera ubwino. chithandizo chapamwamba cha membrane.

Kuphatikiza apo, kuyeretsa madzi a nembanemba nthawi zambiri kumakhala ndi vuto la kutulutsa madzi mokhazikika, komanso kumafunikira thandizo kuchokera kuukadaulo wina, kotero sikuli wamphamvu zonse.

Kusamvetsetsa 6: Kuchuluka kwa membrane, kumakhala bwino

Munjira zina, kuchulukitsa kuchuluka kwa nembanemba kumatha kupititsa patsogolo chitetezo chamadzi pamakina a membrane ndikuchepetsa mtengo wogwirira ntchito.

Komabe, pamene chiwerengero cha nembanemba chikuwonjezeka pamwamba pa mtengo wabwino kwambiri, kuchuluka kwa madzi kufalikira pa nembanemba ya unit kumachepa, ndipo kuthamanga kwa madzi osefedwa pamtunda kumakhala kotsika kwambiri kuposa mtengo wofunikira, zonyansa pamtunda wa membrane sangathe. kuchotsedwa, zomwe zimabweretsa kuwonjezereka kwa kuipitsa ndi kutsekeka kwa nembanemba, ndipo kupanga madzi kumachepa.

Kuonjezera apo, ngati chiwerengero cha nembanemba chikuwonjezeka, kuchuluka kwa madzi osamba kumawonjezeka. Ngati kusamba mpope ndi kuchuluka kwa wothinikizidwa mpweya sangathe kukwaniritsa chofunika kuchuluka kwa madzi ochapira pa unit nembanemba dera dera, zidzakhala zovuta kutsuka bwinobwino, nembanemba kuipitsa kumawonjezeka, ndi ntchito kupanga madzi amakhudzidwa, zomwe ndi zofunika kwambiri kwa MBR kapena UF. nembanemba.

Kupatula apo, kuchuluka kwa nembanemba kuchulukirachulukira, kusungitsa ndalama kamodzi kokha komanso kutsika kwamtengo wamagetsi kumachulukirachulukira.
