Momwe mungagwiritsire ntchito nembanemba yatsopano ya RO reverse osmosis molondola?

• Mfundo zaukadaulo zogwiritsa ntchito nembanemba yatsopano ya RO reverse osmosis:
  Choyamba, tsukani mchenga wa quartz ndi chipolopolo cha kokonati chokhala ndi carbon, ndikutsuka mchenga wa quartz watsopano ndi chipolopolo cha kokonati chokhala ndi carbon kwa nthawi yaitali.
  2. Yang'anani ngati pali klorini yotsalira, ngati chlorine yotsalayo ikupitirira muyezo, thetsani vuto la klorini yotsalayo ndipo pitirirani ku sitepe yotsatira ya RO reverse osmosis nembanemba.
  3. Pambuyo pa filimu yatsopanoyi, thirirani madzi ndikuthira filimuyo kwa maola 1 ~ 2, chifukwa ndi filimu yowuma, filimu yowonongeka imakhala yonyowa kwambiri kuti filimuyo isawonongeke chifukwa cha kuthamanga kwambiri.
  4. Kenaka yambani mpope wothamanga kwambiri, kupanikizika kuyenera kuwonjezeka pang'onopang'ono, kuchokera pa 2 kg mpaka 8 ~ 10 kg, mlingo wa desalination wa nembanemba watsopano uli bwino.
  5. Klorini yotsalira imayendetsedwa pansi pa 0.003.
  6. Tsegulani valavu yowonongeka yamadzi musanayambe kupopera mpweya wothamanga kwambiri, ndipo pang'onopang'ono musinthe valve yamadzi yowonongeka pambuyo potsegula pampu yamagetsi kuti muzitha kuwongolera kuchira kwa nembanemba imodzi ndi pafupifupi 15%.
  7. Madzi opangidwa mu theka loyamba la ola ayenera kukhetsedwa, chifukwa pali madzi otetezera mu membrane kuti asasokoneze kukoma kwa madzi.
  8. Dziwani PH mtengo wamadzi okhudzidwa, pamwamba pa 6.5.

• Kodi mungaweruze bwanji kuti nembanemba ya reverse osmosis iyenera kutsukidwa?

Zinthu zosinthika za osmosis zimatha kugwiritsidwa ntchito pafupifupi zaka 2-3. Ngati mukufuna kukulitsa moyo wautumiki, mutha kuyeretsa zinthu zam'mbuyo za osmosis, zomwe nthawi zambiri zimagawidwa m'njira ziwiri: kutulutsa thupi komanso kutulutsa mankhwala. Zinthu zosinthika za osmosis zimatha kugwiritsidwa ntchito pafupifupi zaka 2-3. Ngati mukufuna kukulitsa moyo wautumiki, mutha kuyeretsa zinthu zam'mbuyo za osmosis, zomwe nthawi zambiri zimagawidwa m'njira ziwiri: kutulutsa thupi komanso kutulutsa mankhwala.

Kuyeretsa kwa nembanemba ya reverse osmosis

Monga lamulo, ngati reverse osmosis unit imatsukidwa miyezi itatu iliyonse kapena kupitilira apo. Ngati amatsukidwa kamodzi pa miyezi 1-3, m'pofunika kusintha mmene ntchito ndi kusintha zotsatira pretreatment.

Weruzani mkhalidwe woyeretsa:

(1) Kupanga madzi abwino okhazikika kwatsika ndi 10%.

(2) Kuchuluka kwa mchere wokhazikika kwawonjezeka ndi 10%.

(3) Pofuna kusunga madzi abwino othamanga madzi abwino, kusiyana kwapakati pakati pa madzi odyetsa ndi madzi osungunuka kumawonjezeka ndi 10% pambuyo pa kutentha kwa kutentha.

(4) Chipangizo chamkati chimakhala ndi zowononga kwambiri komanso sikelo.

(5) Chida cha RO chisanayambe kutsekedwa kwa nthawi yaitali.

(6) Kukonza chizolowezi cha zida za RO.

Zoipitsa

Zoipitsa zodziwika bwino m'magulu a reverse osmosis membrane makamaka ndi CaCO3, CaSO4, BaSO4, SrSO4, ma oxides achitsulo, ma depositi a silicon, organic matter ndi biological slime. Pamene ma scale inhibitor dosing system kapena acid addition system ikalephera, CaCO3 ikhoza kuikidwa mu membrane, ndipo kuyeretsa mankhwala kuyenera kugwiritsidwa ntchito poyeretsa cyclic kapena kuviika usiku wonse.

Kupanga

Zowononga zosiyanasiyana zimayambitsa kuwonongeka kwa nembanemba, ndipo zoipitsa zosiyanasiyana zimagwiritsa ntchito njira zosiyanasiyana zoyeretsera.

Zida zoyeretsera

Nthawi zambiri amapangidwa ndi pampu yoyeretsera, bokosi lokonzekera mankhwala, fyuluta yachitetezo ya 5-20um, chotenthetsera, mavavu amapaipi ogwirizana ndi zida zowongolera.

Njira zoyeretsera zimaphatikizapo kulowetsedwa kosasunthika komanso kuyeretsa mozungulira. Kulowetsedwa kosasunthika kumanyowetsedwa mumadzi oyeretsera, ndipo nthawiyo imakhala pafupifupi 1-15h kutengera kuchuluka kwa kuipitsa. Njira zoyeretsera pa cyclic ndi:

1. Pompani madzi abwino kuchokera mubokosi lokonzekera mu chotengera chokakamiza ndikuchichotsa kwa mphindi zingapo.

2. Konzani njira yoyeretsera ndi madzi abwino mubokosi lokonzekera.

3. Yendetsani chotengera choponderezedwa ndi madzi oyeretsera kwa ola limodzi kapena kufikira nthawi yoyikidwiratu. Mlingo woyeretsa ukhoza kutsimikiziridwa molingana ndi tebulo ili m'munsimu, ndipo kuipitsidwa kukakhala koopsa, kuyeretsa kungathe kuwonjezereka mpaka 150% ya utomoni patebulo. Pakadali pano, kutsika kwamphamvu yoyeretsa ndikwambiri, ndipo kuwongolera konseko sikupitilira (0.10-0.14MPa)/root film element kapena 0.4MPa/root film assembly. Kumayambiriro kwa kutsukidwa kwa mankhwala, 50% ya mtengo wotuluka mu mita ingagwiritsidwe ntchito kutsanulira njira yoyeretsera yotenthetsera mu chotengera chopondereza kuti chiwongolere kupanikizika, kuti athe kuthana ndi kutsika kwapakati pakati pa cholowera ndi madzi otulutsira popanda madzi abwino kutuluka. Pofuna kupewa kusungunuka kwa njira yoyeretsera, valavu yotulutsa madzi yowonongeka ikhoza kutsegulidwa kuti ikhetse madzi osonkhanitsidwa kuchokera ku dongosolo musanayambe kuyeretsa. Dongosolo la reverse osmosis litha kutsukidwa m'magawo. Mayendedwe oyeretsera ndi ofanana ndi momwe akuthamangira, ndipo kuyeretsa m'mbuyo sikuloledwa, apo ayi kungayambitse mpukutu wa filimuyo ndikuwononga filimuyo.

4. Pambuyo poyeretsa mkombero, sambani bokosi lokonzekera ndi madzi abwino.

5. Muzimutsuka chotengera chopondereza ndi madzi abwino.

6. Mukatsuka, yendetsani reverse osmosis system ndi valavu yotulutsa madzi abwino yotsegula mpaka madzi abwino atakhala oyera, opanda thovu, kapena opanda madzi oyeretsera, omwe nthawi zambiri amatenga mphindi 15-30.

Reverse osmosis membrane m'malo

Pambuyo pakugwira ntchito kwanthawi zonse kwa zida za reverse osmosis kwakanthawi, zinthu zam'mbuyo za osmosis zimayipitsidwa ndi zolimba zoyimitsidwa kapena mchere wosasungunuka womwe ungakhalepo m'madzi odyetsa, ndipo zotsatirazi ziziwoneka:

1. Kulemera kwa nembanemba zinthu za reverse osmosis zida chawonjezeka;
2. Mlingo wochotsa membrane wa RO unakula kapena kuchepa kwambiri;
3. Pakupanikizika kwanthawi zonse, kutulutsa madzi kwa zida za reverse osmosis kudachepa kwambiri.
4. Kuti mukwaniritse zokolola zamadzi, mphamvu yogwiritsira ntchito iyenera kukonzedwa;
5. Kutsika kwamphamvu pakati pa madzi okhudzidwa ndi madzi okhazikika a zida za reverse osmosis kumawonjezeka;
6. Chotsani chinthu cha nembanemba mu chotengera chokakamiza, tsanulirani madzi kumbali yolowera ya chinthu chowongoka cha nembanemba, ngati madzi sangathe kuyenda kudzera mu membrane, amasefukira kuchokera kumapeto kwa nkhope, kuwonetsa kuti njira yolowera yolowera yatsekedwa.
