1. Tsanangudzo yemaitiro Mvura yakasvibira imvura yemugodhi, ine yakaturikwa yakakwira yakaomeswa uye kuoma kwakanyanya.Kuti iite kuti mvura iri kuuya isangane nezvinodiwa zve reverse osmosis inflow, muchina sefa inoiswa ine yakanaka quartz jecha mukati kuti ibvise yakaturikwa yakaoma uye sediment mumvura.Nemamwe matsvina.Kuwedzera chiyero inhibitor system inogona kuwedzera scale inhibitor chero nguva kudzikisa tsika yekuomarara ion kuyera mumvura uye kudzivirira kudzika kwemvura chimiro.Sefa yehuchi chaiyo inoiswa sefa yehuchi-maronda ine hutsanana hwemamicrons mashanu kuti iwedzere kubvisa zvidimbu zvakaoma mumvura uye kudzivirira pamusoro pemembrane kuti isakwekwe.Iyo reverse osmosis mudziyo ndiyo yakakosha desalination chikamu chemidziyo.Iyo single-stage reverse osmosis inogona kubvisa 98% yemunyu ions mumvura, uye kusvibiswa kwechipiri-danho reverse osmosis kunosangana nezvinodiwa nemushandisi.
2. Mechanical filter operation
- Exhaust: Vhura vharuvhu yekuyerera yepamusoro uye yekumusoro inlet valve kutumira mvura musefa kune yekumusoro discharge valve kuti irambe ichipinda mvura.
- Positive washing: Vhura vharuvhu yekudonhedza yezasi uye yekumusoro inlet valve kuti mvura ipfuure nepasefa layer kubva kumusoro ichienda pasi.Chiyero chekuyerera kwemukati i10t/h.Zvinotora anenge 10-20 maminitsi kusvikira mvura yakachena uye yakajeka.
- Kushanda: Vhura vharuvhu yekuburitsa mvura kutumira mvura kumidziyo yepasi.
- Backwashing: Mushure mekunge midziyo yave ichimhanya kwenguva yakati, nekuda kwetsvina yakabatwa, mafirita makeke anoumbwa pamusoro.Kana mutsauko wekumanikidza pakati pekupinda nekubuda kwesefa wakakura kupfuura 0.05-0.08MPa, kugezeswa kumashure kunofanirwa kuitwa kuti ive nechokwadi chekuyerera kwemvura.Vhura iyo yekumusoro yekudhonza valve, backwash valve, bypass valve, flush ne 10t / h kuyerera, anenge 20-30 maminitsi, kusvikira mvura yakachena.Ongorora: Mushure mekugezeswa kumashure, yekumberi yekugezesa midziyo inofanirwa kuitwa isati yaiswa mukushanda.
3. Softener switching cleaning Nheyo yekushanda yekunyorovesa ndeye ion exchange.Hunhu hweiyo ion exchanger ndeyekuti resin inofanira kuvandudzwa kazhinji.Chenjerera kune zvinotevera nyaya paunenge uchishandisa:
- Kana kuoma kwehutano hwemvura yakasvibiswa kupfuura chiyero (chinodiwa chekuoma ≤0.03mmol / L), inofanira kumira uye kuvandudzwa;2. Iyo cationic resin regeneration nzira ndeyekunyudza resin mumvura yemunyu kwemaawa anenge maviri, rega mvura yemunyu iome, uye woishandisa.Mvura yakachena inodzokera, unogona kuramba uchiishandisa;
4. Kuwedzera antiscalant system Iyo metering pump uye yepamusoro-pressure pombi inotanga uye inomira panguva imwe chete, uye kufamba synchronously.Scale inhibitor iMDC150 yakagadzirwa muUnited States.The dosage of scale inhibitor: Zvinoenderana nekuoma kwemvura mbishi, mushure mekuverenga, muyero weiyo antiscalant ndeye 3-4 magiramu patani yemvura mbishi.Mvura yekudyara yehurongwa ndeye 10t / h, uye muyero paawa ndeye 30-40 gramu.Kugadziriswa kwechiyero inhibitor: wedzera 90 malita emvura kune tangi remakemikari, wobva wawedzera zvishoma nezvishoma 10 kg ye scale inhibitor, uye sanganisa zvakanaka.Gadzirisa metering pombi renji kune chiyero chinoenderana.Ongorora: Iyo yakaderera yekumisikidzwa kwe scale inhibitor haifanire kunge iri pasi pe10%.
5. Sefa chaiyo Sefa yechokwadi ine kukwenenzvera kwe5μm.Kuti uchengetedze kurongeka kwefiltration, iyo system haina pombi yekudzosera kumashure.Iyo sefa chinhu mune chaiyo sefa inowanzogara kwemwedzi 2-3, uye inogona kuwedzerwa kusvika kumwedzi 5-6 zvichienderana nehuwandu hwekurapa kwemvura.Dzimwe nguva kuitira kuchengetedza kuyerera kwemvura, iyo sefa chinhu chinogona kutsiviwa pachine nguva.
6. Reverse osmosis kuchenesa Reverse osmosis membrane zvinhu zvinowanzoita scaling nekuda kwekuunganidza kwetsvina mumvura kwenguva yakareba, zvichiita kuti kuderera kwekugadzirwa kwemvura uye kuderera kwehuwandu hwe desalination.Panguva ino, membrane element inoda kucheneswa nemakemikari.
Kana iyo midziyo iine imwe yeanotevera mamiriro, inofanirwa kucheneswa:
- Chigadzirwa chekuyerera kwemvura inodonha kusvika 10-15% yeyakajairika kukosha pasi pekumanikidzwa kwakajairika;
- Kuti uchengetedze yakajairika chigadzirwa mvura inoyerera mwero, kudzvinyirirwa kwemvura yekudyisa mushure mekugadzirisa tembiricha yakawedzera ne10-15%;3. Chigadzirwa chemvura yemhando yakaderedzwa ne10-15%;iyo munyu permeability yakawedzera ne10-15%;4. Kumanikidzwa kwekushanda kwakawedzerwa ne10- 15%.15%;5. Kusiyana kwekumanikidzwa pakati pezvikamu zveRO kwakawedzera zvakanyanya.
7. Nzira yekuchengetedza ye membrane element:
Yenguva pfupi yekuchengetedza inokodzera reverse osmosis masisitimu ayo akavharwa kwemazuva 5-30.
Panguva ino, membrane element ichiri kuiswa mumudziyo wekumanikidza weiyo system.
- Shamba iyo reverse osmosis system nemvura yekudyisa, uye teerera kuti ubvise zvachose gasi kubva muhurongwa;
- Mushure mekunge mudziyo wekumanikidza uye mapaipi ane hukama akazadzwa nemvura, vhara mavharuvhu akakodzera kudzivirira gasi kupinda muhurongwa;
- Ese mazuva mashanu Shamba kamwe chete sezvatsanangurwa pamusoro.
Yenguva refu deactivation kudzivirira
- Kuchenesa membrane zvinhu muhurongwa;
- Gadzirira mvura inouraya ine reverse osmosis inogadzirwa mvura, uye geza reverse osmosis system nemvura inouraya;
- Mushure mekuzadza reverse osmosis system nemvura inouraya, vhara mavharuvhu akakodzera Chengetedza mvura inouraya muhurongwa.Panguva ino, ita shuwa kuti iyo system yakazadzwa zvachose;
- Kana tembiricha yehurongwa yakadzikira kupfuura 27 madhigirii, inofanirwa kushandirwa nemvura itsva inouraya mazuva makumi matatu ega ega;kana tembiricha yakakwira kupfuura 27 madhigirii, inofanirwa kushandirwa mazuva makumi matatu ega ega.Tsiva mushonga westerilizing mazuva gumi nemashanu ega ega;
- Isati yaiswa reverse osmosis system zvakare, geza sisitimu nemvura yakaderera-yekudyisa kweawa imwe, wobva wagezesa sisitimu yacho nemvura yekudzvinyirirwa yakakura kwemaminetsi mashanu-10;pasinei ne-low-pressure kana high-pressure flushing, mvura yechigadzirwa chemvura Yese mavharuvhu emvura anofanira kunge akazaruka zvakakwana.Isati yatangazve kushanda kwakajairika, tarisa uye simbisa kuti mvura yechigadzirwa haina chero fungicides
