Kushandiswa kwepamusoro-inoshanda reverse osmosis membrane zvinhu mukurapwa kwetsvina

RO membrane yekuparadzanisa tekinoroji

RO membrane yekuparadzanisa tekinoroji inoshandisa iyo static pressure mutsauko pane iyo membrane sesimba rekutyaira. Mamorekuru madiki, akadai semamorekuru emvura, anokunda iyo osmotic kudzvanywa kuti ipfuure nepakati pe RO membrane, nekudaro achivaparadzanisa kubva kutsvina. Kumanikidza kwekushanda kunowanzo kuve pakati pe1.5 uye 10.5 MPa, uye sisitimu inogona kuchengetedza mamorekuru madiki e1 kusvika 10A.

Mukurapa kwemvura, RO, sechishandiso chakakosha, inogona kubvisa zvinopfuura 97% yezvakanyunguduka inorganic matter, 99% ye organic matter ine hama molecular uremu hwe300 kana pamusoro, kupfuura 99% yezvikamu zvakasiyana zvinosanganisira mabhakitiriya, uye 95% yeSiO2 mumvura.

Iyo hombe yepamusha yekushandisa nzvimbo ye reverse osmosis membranes inoramba yakakura-yakakura boiler yekudyisa mvura, inoteverwa neakasiyana maindasitiri emvura yakachena uye misika yemvura yekunwa. Membrane application yasvikawo pachiyero chakakosha mumagetsi, semiconductor, mishonga, yekurapa, chikafu, chinwiwa, doro, makemikari, kuchengetedza kwezvakatipoteredza, metallurgy, uye maindasitiri emachira. Zvishandiso zvenguva yemberi zvinosanganisa kugezwa kwemvura yetsvina yemagetsi inotonhodza mvura, hombe-yakakura yemvura yegungwa kubvisa salination, brackish water desalination, uye hukuru hwakakura hwemanisiparati nemaindasitiri emarara.

Kushandiswa kweRO membrane mukurapwa kwetsvina

1Kushandiswa mukugadziriswa kwemvura yakasviba yakawanda-munyu

(1) Kugadziriswa kwemvura yakasviba yakakwira-mineralization, inomiririrwa nemvura yemugodhi, inoratidzirwa nemunyu wakanyanya, kunyanya kubuda kwemvura yepasi, ine avhareji yemunyu inodarika 1000 mg/L. Izvo zvinokonzerwa nehupenyu hweSS ine huwandu hukuru hweCa2+Mg2+K+, Cl-, SO42-, HCO3 uye HCO3- isingasviki 1.5 mg/L. Kune nzvimbo dzemigodhi dzine kushomeka kwakanyanya kwemvura, kushandiswa kwereverse osmosis tekinoroji yekurapa kwakadzama kwekugadzira uye mvura yemumba kwakasimudzirwa zvakanyanya.

Kushandisa mineral water se pretreatment agent, flocculation, sedimentation, uye kukurumidza kusefa kwakawedzerwa kubvisa yakawanda yeSSS mumvura, zvichiita kuti reverse osmosis inlet turbidity isingasviki 1 NTU. Mushure mekudzoreredza kurapwa kweosmosis, mwero wekubvisa turbidity wakasvika 100%, uine desanation rate ye96%.

(2) Metallurgical wastewater treatment

Indasitiri yesimbi, indasitiri ine zviwanikwa, inotora mvura yakawanda uye inosvibisa zvakanyanya, inotora 14% yehuwandu hwemvura inoshandiswa neChina. Simbi indasitiri tsvina mvura inoshandiswa zvakanyanya muindasitiri yesimbi. Mvura yetsvina ine yakaomesesa kuumbwa uye inochinja zvakanyanya mumhando dzakasiyana siyana, kunyanya yakakwirira yeCa2+, Mg2+, Fe2+, Mn2+, SO42-, F, uye SiO2. Kutadza kufanobvisa iyo yakakwira-simbi inoburitsa iripo pane reverse osmosis membrane inogona kutungamira kune yakakomba inorganic kusvibiswa.

Kumvura yetsvina kubva muchirimwa chesimbi ichirapwa chechipiri chebiochemical, kufefetera kunotanga kuitwa mutangi remhepo kuti oxidize Fe2+ kusvika Fe3+. Panguva imwe cheteyo, NaClO inowedzerwa kuwedzera Fe2+ oxidation kugona uye kushanda kwebhakitiriya. Mukaka weLime unowedzerwa kugadzirisa pH, uchiteverwa nekuyerera nePAM nePAC. Sedimentation, kukurumidza kusefa, uye activated kabhoni adsorption zvinobva zvashandiswa kubvisa organic matter, residual chlorine, uye heavy metal ions. Kutevera kurapwa kweUF, tsvina inobatwa neinoderedza. Scale inhibitors uye asidhi inopinda muRO system.

2 Kushandiswa mukurapa refractory organic wastewater

Kudhinda uye kudhaya mvura yetsvina uye petrochemical tsvina yemvura, kudhinda uye kudhayira mvura yetsvina, kuwedzera kune yakawanda dhayi, slurries, inorganic munyu, acids uye alkalis, ine hunhu hunosvika 4000 nguva yeruvara, hukuru hwemvura, yakakwira yezvinhu zvinosvibisa organic, hutano hwemvura hwakasiyana-siyana, kushaikwa kwemvura kunobva kune yakadzika biodegrad sedimentation yenzvimbo dzinoraswa ivhu, uye zvinosvibisa zvinonyanya kubva mukuora kwehutachiona hwemarara uye kudonha kwemvura. Hunhu hwemvura hwakaoma, uye COD yakakwirira zvikuru kupfuura yetsvina yemuguta. Pamusoro pezvo, iyo leachate inewo akasiyana maion simbi, akadai seFe2+, Cd2+, Cr3+, Cu2+, Zn2+, uye Fe2+ concentration panguva yekuvirisa.

Kunyangwe iyo A/O-matanho maviri ebiochemical kurapwa maitiro akashandiswa zvakanyanya kune organic kushatisa uye denitrification mumarara emarara, kuita kwemvura hakuna kugadzikana. Nokudaro, zvichibva pamagetsi ekusefa, kushandiswa kwe ultrafiltration membranes uye A / O kugadzira chirongwa cheMBR chakavandudza kubviswa kwehuwandu hwehupenyu mumararamiro emarara.

Iyo tsvina, mushure mekuparadzaniswa kwedhaka kuburikidza ne ultrafiltration membranes, inopinda nanofiltration (NFN) system. NF inogona kunyatsoparadzanisa organic matter ine molecular weight ye 200m kusvika 2000m uye inogonawo kushandiswa kuparadzanisa imwe yepamusoro-yakakosha organic matter kubva mumvura inogadzirwa neMBR. Tsvagiridzo yakaitwa pamusoro pezvinhu zvesimbi ions uye iyo MBR+NF+RO matatu-layer membrane composite kurapwa maitiro. Mibairo inoratidza kuti hurongwa uhwu hunoshanda nemazvo, uye mhando yetsvina inosangana nezviyero zvekudzora kusvibiswa kwemarara emarara.

Panguva yekushanda, kana tsvina yeNF ikasangana nezvinodiwa pakubuda, inogona kubudiswa zvakananga. Zvikasadaro, inogona kurapwa zvakare uchishandisa inotevera RO system. Tsvagiridzo yeAr/O-MBR+NF+RO nzira yekurapa leachate yemarara yakaratidza kuti kuwedzerwa kweiyo activated kabhoni kuA/O reactor haingonatsiridze kubviswa kweiyo organic matter uye inorema simbi asi zvakare inoderedza membrane foiling.

3 Kushandiswa mukurapa kwemhando yepamusoro kudzokorodza zvakare

China yakagadzirawo zvidyarwa zvakakura zvakadzokororwa mvura muBeijing, Tianjin, Hebei, Shandong nedzimwe nzvimbo. Pakati pazvo, zviteshi zvakakura zvakadzokororwa zvekudzoreredza mvura zvinoshandisa "UF (MF) + RO" kaviri membrane process kubata marudzi maviri etsvina yemumaguta mumvura yakasvibira, ichigadzira mvura yemhando yepamusoro yakadzokororwa, iyo inoshandiswa sechikamu chemvura yekubikira magetsi emagetsi emagetsi uye chimwe chikamu chinoshandiswa senzizi dzenzvimbo uye mvura yemumba yakasiyana.

Chigadzirwa chemuno chekuchenesa mvura yetsvina chinoshandisa MBR yakasanganiswa nereverse osmosis kurapa tsvina yemunisiparati kuti ishandiswezve. Mvura yakawana mazinga eTOC

Kuti ikwidze zvakazara zvakanakira reverse osmosis tekinoroji, kuderedza kusvibiswa kwemembrane, uye mitengo yakaderera yekurapa mvura, kambani yedu yakagadzira akateedzana maitiro akasanganiswa akagadzirirwa hunhu hwemvura. Nzira dzechinyakare dzekurapa mvura, dzakaita senge coagulation uye sedimentation, high-concentration, uye high-efficiency filtration, dzinowanzo shandiswa kubvisa SS. NaClO, lime mukaka, uye manganese mafirita ejecha anoshandiswa kuderedza RO, manganese munyu, calcium munyu, uye silica munyu mune inofurira Sargassum aeration uye oxidation system. O3 oxidation inoshandiswa kurapa recalcitrant A/O organic nyaya. MBR, UF, uye NF anoshandiswa kuchengetedza yakanaka SS uye madiki organic mamorekuru. High-valent ions inosanganiswa neUF + RO kana MBR + RO mbiri-membrane masisitimu, kana kunyange MBR + NF + RO katatu-membrane masisitimu, kuve nechokwadi chekushanda kwakagadzikana kwehurongwa uye kuve nechokwadi chekurapa kweRO kwerecalcitrant organic wastewater.
