1. Tlhaloso ea ts'ebetso Metsi a tala ke metsi a seliba, a nang le lintho tse tiileng tse emisitsoeng le boima bo phahameng. E le ho etsa hore metsi a kenang a finyelle litlhoko tsa reverse osmosis phallo, mochine oa mochine o kenngoa ka lehlabathe le letle la quartz ka hare ho tlosa lintho tse tiileng le sediment ka metsing. Le litšila tse ling. Ho kenyelletsa scale inhibitor system e ka eketsa scale inhibitor ka nako leha e le efe ho fokotsa tšekamelo ea ho thatafala ha ion ka metsing le ho thibela sebopeho sa metsi a mangata. Sefefo se nepahetseng se na le sesefe sa leqeba la mahe a linotši ka nepo ea li-micron tse 5 ho tsoela pele ho tlosa likaroloana tse thata ka metsing le ho thibela bokaholimo ba lera ho ngoauoa. Sesebelisoa sa reverse osmosis ke karolo ea mantlha ea ho ntša letsoai metsing. The single-stage reverse osmosis e ka tlosa 98% ea li-ion tsa letsoai metsing, 'me metsi a tsoang mothating oa bobeli oa reverse osmosis a fihlela litlhoko tsa basebelisi.
2. Ts'ebetso ea filthara ea mochini
- Exhaust: Bula valve e ka holimo ea ho ntša metsi le valve e ka holimo ea ho kenya metsi ho romela metsi ka har'a filthara ho ea holimo bakeng sa ho kena ha metsi ho tsoelang pele.
- Ho hlatsoa hamonate: Bula valve e ka tlaase ea drain le valve ea ho kena ka holimo ho etsa hore metsi a fete ka har'a lesela la sefe ho tloha holimo ho ea tlaase. Sekhahla sa phallo e kenang ke 10t/h. Ho nka metsotso e ka bang 10-20 ho fihlela drainage e hlakile ebile e hlakile.
- Tshebetso: Bula valve ea ho ntša metsi ho romela metsi ho thepa e tlaase.
- Ho hlatsoa ka morao: Ka mor'a hore thepa e sebetse ka nako e itseng, ka lebaka la litšila tse koaletsoeng, likuku tsa filthara li thehoa holim'a metsi. Ha phapang ea khatello pakeng tsa ho kena le ho tsoa ha filthara e le kholo ho feta 0.05-0.08MPa, ho hlatsoa mokokotlo ho lokela ho etsoa ho netefatsa hore metsi a phalla hantle. Bula valve e ka holimo ea drain, valve ea backwash, valve ea bypass, e phalla ka 10t / h, hoo e ka bang metsotso ea 20-30, ho fihlela metsi a hlakile. Tlhokomeliso: Kamora ho hlatsuoa ka morao, lisebelisoa tsa ho hlatsoa pele li tlameha ho etsoa pele li ka qala ho sebetsa.
3. Softener switching Cleaning Molao-motheo oa ho sebetsa oa softener ke phapanyetsano ea ion. Tšobotsi ea ion exchanger ke hore resin e lokela ho tsosolosoa khafetsa. Ela hloko lintlha tse latelang ha u sebelisa:
- Ha boima ba boleng ba metsi a litšila bo feta tekanyo (tlhoko ea boima ≤0.03mmol / L), e tlameha ho emisoa le ho tsosolosoa; 2. Mokhoa oa ho tsosolosa resin ea cationic ke ho kenya resin metsing a letsoai ka lihora tse ka bang peli, tlohela metsi a letsoai a omelle, ebe oe sebelisa. Metsi a hloekileng a theoha, o ka tsoela pele ho a sebelisa;
4. Ho eketsa tsamaiso ea antiscant Pompo ea metering le pompo ea khatello e phahameng e qala le ho emisa ka nako e le 'ngoe,' me e tsamaee ka synchronously. The scale inhibitor ke MDC150 e hlahisoang United States. Tekanyetso ea scale inhibitor: Ho ea ka boima ba metsi a tala, ka mor'a ho bala, tekanyo ea antiscaant ke 3-4 grams ka tone ea metsi a tala. Ho noa metsi a tsamaiso ke 10t / h, 'me tekanyo ea hora ke 30-40 dikgerama. Ho hlophisoa ha scale inhibitor: eketsa lilithara tse 90 tsa metsi ka tanka ea lik'hemik'hale, ebe butle-butle eketsa 10 kg ea scale inhibitor, 'me u kopanye hantle. Fetola sebaka sa pompo ea metering ho sekala se lumellanang. Tlhokomeliso: Tekanyetso e tlase ea scale inhibitor ha ea lokela ho ba ka tlase ho 10%.
5. Sesepa se nepahetseng Sesefa se nepahetseng se na le ho nepahala ha 5μm. E le ho boloka ho nepahala ha filtration, tsamaiso ha e na pipeline ea backwash. Sesefa se sefang se nepahetseng hangata se nka likhoeli tse 2-3, 'me se ka eketsoa ho isa likhoeling tse 5-6 ho latela bophahamo ba metsi a 'nete. Ka linako tse ling e le ho boloka phallo ea metsi, karolo ea filthara e ka nkeloa sebaka esale pele.
6. Reverse osmosis hloekisa Reverse osmosis lera lintho tse le tšekamelo ea ho scaling ka lebaka la ho bokella litšila ka metsing nako e telele, ho fella ka ho fokotseha ha tlhahiso ea metsi le ho fokotseha ha desalination lebelo. Nakong ena, karolo ea membrane e hloka ho hloekisoa ka lik'hemik'hale.
Ha thepa e na le e 'ngoe ea maemo a latelang, e tlameha ho hloekisoa:
- Sekhahla sa phallo ea metsi a sehlahisoa se theohela ho 10-15% ea boleng bo tloaelehileng tlas'a khatello e tloaelehileng;
- E le ho boloka tekanyo e tloaelehileng ea ho phalla ha metsi a sehlahisoa, khatello ea metsi a fepa ka mor'a hore ho lokisoe mocheso o eketsehile ka 10-15%; 3. Boleng ba metsi a sehlahisoa bo fokotsehile ka 10-15%; ho kenella ha letsoai ho eketsehile ka 10-15%; 4. Khatello ea ts'ebetso e eketsehile ka 10- 15%. 15%; 5. Phapang ea khatello pakeng tsa likarolo tsa RO e eketsehile haholo.
7. Mokhoa oa ho boloka oa membrane element:
Polokelo ea nako e khuts'oane e loketse lits'ebetso tsa reverse osmosis tse koetsoeng ka matsatsi a 5-30.
Ka nako ena, membrane element e ntse e kentsoe ka har'a sekepe sa khatello ea sistimi.
- Hlakola tsamaiso ea reverse osmosis ka metsi a fepa, 'me u ele hloko ho tlosa khase ka ho feletseng tsamaisong;
- Ka mor'a hore sekepe sa khatello le liphaephe tse amanang le tsona li tlatsoe ka metsi, koala li-valve tse amehang ho thibela khase ho kena tsamaisong;
- Matsatsi a mang le a mang a 5 Hlatsoa hang joalo ka ha ho hlalositsoe ka holimo.
Tšireletso ea nako e telele ea ho tima
- Ho hloekisa likarolo tsa lera tsamaisong;
- Lokisetsa mokelikeli o thibelang likokoana-hloko ka metsi a hlahisoeng a reverse osmosis, 'me u hlatsoe tsamaiso ea reverse osmosis ka mokelikeli o thibelang likokoana-hloko;
- Kamora ho tlatsa sistimi ea reverse osmosis ka mokelikeli o thibelang likokoana-hloko, koala li-valve tse amehang Boloka mokelikeli o thibelang likokoana-hloko ka har'a sistimi. Ka nako ena, etsa bonnete ba hore tsamaiso e tletse ka ho feletseng;
- Haeba mocheso oa sistimi o le ka tlase ho likhato tse 27, o lokela ho sebetsoa ka mokelikeli o mocha oa ho hloekisa ka matsatsi a mang le a mang a 30; Haeba mocheso o phahame ho feta likhato tse 27, o lokela ho sebelisoa matsatsi a mang le a mang a 30. Fetola tharollo ea sterilizing ka matsatsi a mang le a mang a 15;
- Pele tsamaiso ea reverse osmosis e sebelisoa hape, hlatsoa sisteme ka metsi a fepeloang ka khatello e tlase bakeng sa hora e le 'ngoe, ebe o hlatsoa sistimi ka metsi a phepelo ea khatello e phahameng bakeng sa metsotso e 5-10; ho sa tsotelehe khatello e tlase kapa khatello e phahameng ea khatello, metsi a sehlahisoa sa sistimi Li-valve tsohle tsa drain li lokela ho buleha ka botlalo. Pele tsamaiso e qala ts'ebetso e tloaelehileng, hlahloba 'me u netefatse hore metsi a sehlahisoa ha a na li-fungicides
