Mushure meiyo reverse osmosis sisitimu yemvura yekupedzisira, michina yave ichishanda kwenguva yakati rebei, dzimwe nguva mhedzisiro yekurapa ichaderedzwa zvakanyanya, uye iyo yakagadzirirwa kugona kwemidziyo haisvikike. Chikonzero chechiitiko ichi chinonyanya kuenderana nemamiriro ekushanda emidziyo, dhizaini yekusarudza, kuisirwa uye kuvaka, manejimendi ekushanda, uye kuita kwechigadzirwa che reverse osmosis michina yekusefa membranes. Izvi zvinotevera zvinonyatso suma zvikonzero zvinokanganisa kugona kugadzirisa kweiyo reverse osmosis system yemuchina wemvura weultrapure.
1. RO Membrane Performance
Iyo anti-fouling uye hydrophilicity ye membrane ye reverse osmosis midziyo ine yakakura kukanganisa pakuyerera. Mushure menguva yekushanda, simba rekugadzirisa richaderedzwa. Kuti ugadzirise dambudziko iri, iwe unofanirwa kutanga wasarudza yakakodzera sefa membrane. Semuenzaniso, muUF maitiro, unogona kusarudza kushandisa yakasimbiswa PVDF membrane ine yakasimba anti-kusvibiswa uye yakanaka yekuchenesa kudzoreredza kuve nechokwadi chekuchenesa maitiro. Kune iyo MBR sisitimu, inodiwa A isingaperi hydrophilic uye isina-shinda yeMBR membrane ine yemukati lining inoshandiswa kuve nechokwadi chekugadzirwa kwemvura uye kunaka kwemvura.
2. Nzvimbo Yekushanda
Kana tembiricha yemvura inopinza yakadzikira pane tembiricha yekugadzira (kazhinji nekuda kwekushanduka kwemwaka), zvinokonzeresa kuburitsa kwe membrane kuderera; shanduko mumhando uye kuwanda kwezvinosvibisa mumhando yemvura uye viscosity yemuviri wemvura ichaitawo kuti mvura ye membrane ive yakaderera pane inotarisirwa. Kuti ugadzirise matambudziko aya, zvinodikanwa kuti utarise huwandu hwekuchinja kweyakadzikira tembiricha yemvura uye mhando yemvura mukati megore pakutanga kweiyo membrane system dhizaini, uye kusiya imwe nzvimbo yekuchengetedza pakusarudza iyo membrane nzvimbo.
3. Sarudzo Dhizaini
Iyo isina kukwana yekuchengetedza muganho weyakasarudzwa reverse osmosis membrane, overestimation yekugadzira mvura inoyerera ye membrane, nezvimwewo, ichaita kuti membrane itadze kusvika kune yakagadziriswa. Kunyangwe iri MBR membrane, UF membrane kana R0 membrane, yakakwana membrane nzvimbo inofanirwa kuve nechokwadi.
4. Kuiswa uye Kuvaka
Mukugadzira uye nekuisa iyo membrane system ye reverse osmosis zvishandiso, kutadza kuchenesa marara nekufamba kwenguva kunozokonzeresa kusvibiswa kwakanyanya kwasara, izvo zvinokanganisa kugadzirwa kwemvura kwe membrane, kunyanya welding slag, inopinza kana filaments, nezvimwewo, izvo zvinokonzeresa membrane filaments uye membrane mumatambudziko akaomarara. Chidimbu chatyoka. Kune MBR membrane, zvakakosha kuchenesa tsvina mudziva usati wapinda mumvura; yeUF neRO masisitimu, tanga wapuruzira pombi yekumberi, shandisa iyo pre-sefa, wozopinda mumvura.
5. Operation Management
Kuwedzerwa kwakaringana kwemakemikari, kunyanya scale inhibitors, kwakakosha zvikuru kuRO system. Mukuwedzera, maererano nemamiriro ekushanda, zvakakosha kushambidza munguva kana kutora mishonga yekugeza kudzorera kushanda kwe membrane.
Chikonzero nei reverse osmosis system isingaburitse mvura
Kazhinji, iyo reverse osmosis membrane yemidziyo yemvura yekupedzisira inozovharika zvishoma nezvishoma panguva yekushandiswa, uye kugadzirwa kwemvura kuchaita kudiki uye kudiki. Kazhinji, reverse osmosis membrane inoda kutsiviwa mukati megore. Mukushandiswa, michina yekuchenesa mvura yakajairika inofanirwa kurasa mvura yetsvina Vamwe vashandisi vanogona kuona mvura yetsvina ichiraswa vonzwa kuparara, votora matanho ekuvharisa kubuda kwetsvina kana kuderedza kubuda kwetsvina. Maitiro akadai anokonzeresa zvakananga kuti reverse osmosis membrane kurasikirwa nemhedzisiro yayo. Kune vakapfuma, zvinokurudzirwa kugadzirisa mvura yetsvina zvichienderana nemhando yemvura yemuno uye zvinokurudzirwa nemugadziri wemidziyo yekuchenesa mvura. Usagadzirise kubuda kwetsvina pakuda.
1. Muchina haubudisi mvura, mvura inopinza solenoid valve yakakuvadzwa, uye hapana mvura yakachena kana tsvina.
2. Iyo yekumberi sefa element yakavharwa, uye ona kana firimu rekudzivirira rabvarurwa uye rakatsiviwa.
3. Iyo RO reverse osmosis membrane sefa element yakavharika, tanga wageza, kana sukurudza isiri iyo, tsiva iyo sefa element.
4. Kana pombi yemvura yakatyoka kana kuti gokora repombi rakavharika, tarisa zvakare uye uise pombi kuti uone kuyerera kwakanaka.
5. Kubuda kwemhepo kana mvura mubhakiti rekuchengetedza mvura, kuwedzera mhepo yemukati kana kutsiva bhakiti rekuchengetedza mvura.
6. Tarisa uone kana paine pombi dzemapombi uye kuvharika kwetepi pamubatanidzwa wega wega. Tarisa iyo sefa element majoini uye tarisa kana paine mbishi zvinhu tepi yakabatwa uye yakavharwa.
