Mfundo zazikuluzikulu zoyika zida ziwiri zosinthira madzi osmosis ......

1. Mafotokozedwe a ndondomeko Madzi aiwisi ndi madzi abwino, okhala ndi zolimba zokhazikika komanso zolimba kwambiri. Kuti madzi omwe akubwera akwaniritse zofunikira za reverse osmosis kulowa, makina fyuluta imayikidwa ndi mchenga wabwino wa quartz mkati kuti achotse zolimba zoyimitsidwa ndi dothi m'madzi. Ndi zonyansa zina. Kuwonjezera ma scale inhibitor system amatha kuwonjezera ma scale inhibitor nthawi iliyonse kuti achepetse chizolowezi cha kuuma ion makulitsidwe m'madzi ndikuletsa madzi kuti asamangidwe. Zosefera zolondola zimakhala ndi zosefera za chilonda cha zisa zomwe zili ndi ma microns 5 kuti zichotse zolimba m'madzi ndikuletsa pamwamba pa nembanemba kuti zisakandidwe. Chipangizo cha reverse osmosis ndiye gawo lalikulu lochotsa mchere pazida. The single-stage reverse osmosis imatha kuchotsa 98% ya ayoni amchere m'madzi, ndipo kutayira kwa gawo lachiwiri reverse osmosis kumakwaniritsa zofunikira za ogwiritsa ntchito.

2. Mawotchi fyuluta ntchito

1. Kutulutsa mpweya: Tsegulani valavu yotulutsira pamwamba ndi valavu yapamwamba yolowera kuti mutumize madzi mu fyuluta ku valavu yapamwamba yotulutsa madzi kuti mulowetse madzi mosalekeza.
2. Kutsuka kwabwino: Tsegulani valavu yokhetsera m'munsi ndi valavu yakumtunda kuti madzi adutse pagawo losefera kuchokera pamwamba mpaka pansi. Mphamvu yolowera ndi 10t/h. Zimatenga pafupifupi mphindi 10-20 mpaka ngalande ikhale yoyera komanso yowonekera.
3. Ntchito: Tsegulani valavu yotulutsira madzi kuti mutumize madzi ku zida zapansi.
4. Kubwerera m'mbuyo: Zida zitakhala zikugwira ntchito kwa nthawi yayitali, chifukwa cha dothi lomwe latsekeredwa, makeke osefera amapangidwa pamwamba. Pamene kusiyana kwapakati pakati pa cholowera ndi chotuluka cha fyuluta ndi chachikulu kuposa 0.05-0.08MPa, kuchapa kumbuyo kuyenera kuchitidwa kuti madzi aziyenda bwino. Tsegulani valavu yakumtunda, valavu ya backwash, valavu yodutsa, sungani ndi kutuluka kwa 10t / h, pafupifupi mphindi 20-30, mpaka madzi amveka bwino. Zindikirani: Pambuyo pochapa msana, zida zochapira kutsogolo ziyenera kuchitidwa zisanayambe kugwira ntchito.

3. Kusintha kwa Softener Mfundo yogwiritsira ntchito chofewa ndi kusinthana kwa ion. Makhalidwe a ion exchanger ndikuti utomoni uyenera kusinthidwa pafupipafupi. Samalani kuzinthu zotsatirazi mukamagwiritsa ntchito:

1. Pamene kuuma kwa khalidwe la madzi otayira kupitirira muyezo (kuuma kofunika ≤0.03mmol / L), kuyenera kuyimitsidwa ndikusinthidwa; 2. Njira yotsitsimutsa cationic resin ndikuthira utomoni m'madzi amchere kwa maola awiri, mulole madzi amchere aume, ndiyeno mugwiritse ntchito. Madzi oyera amatha kuyambiranso, mutha kupitiliza kugwiritsa ntchito;

4. Kuonjezera antiscant system Pampu ya metering ndi pampu yothamanga kwambiri imayamba ndikuyimitsa nthawi imodzi, ndikusuntha synchronously. Scale inhibitor ndi MDC150 yopangidwa ku United States. Mlingo wa scale inhibitor: Malingana ndi kuuma kwa madzi osaphika, mutatha kuwerengera, mlingo wa antiscaant ndi 3-4 magalamu pa tani imodzi ya madzi osaphika. Kumwa madzi kwadongosolo ndi 10t / h, ndipo mlingo pa ola ndi 30-40 magalamu. Kukonzekera kwa scale inhibitor: onjezerani malita 90 a madzi mu thanki ya mankhwala, kenaka yonjezerani pang'onopang'ono 10 kg ya scale inhibitor, ndikusakaniza bwino. Sinthani mtundu wa mpope wa metering kukhala sikelo yofananira. Zindikirani: Kuchuluka kwa scale inhibitor kuyenera kukhala kosachepera 10%.

5. Fyuluta yolondola Sefa yolondola imakhala ndi kusefera kwa 5μm. Pofuna kusunga kulondola kwa kusefera, makinawa alibe payipi ya backwash. Zosefera zomwe zili muzosefera zolondola nthawi zambiri zimatha kwa miyezi 2-3, ndipo zimatha kukulitsidwa mpaka miyezi 5-6 malinga ndi kuchuluka kwenikweni kwamankhwala amadzi. Nthawi zina kuti madzi asamayende bwino, fyulutayo imatha kusinthidwa pasadakhale.

6. Reverse osmosis kuyeretsa Reverse osmosis nembanemba zinthu sachedwa makulitsidwe chifukwa cha kudzikundikira zonyansa m'madzi kwa nthawi yaitali, kuchititsa kuchepa kwa madzi kupanga ndi kuchepa kwa desalination mlingo. Panthawi imeneyi, chinthu cha membrane chiyenera kutsukidwa ndi mankhwala.

Chidacho chikakhala ndi chimodzi mwazinthu izi, chikuyenera kutsukidwa:

1. Kuchuluka kwa madzi opangira mankhwala kumatsika mpaka 10-15% ya mtengo wamba pansi pa kupanikizika kwabwino;
2. Pofuna kusunga madzi abwinobwino, kuthamanga kwa madzi odyetsa pambuyo pakuwongolera kutentha kwawonjezeka ndi 10-15%; 3. Madzi amadzimadzi achepetsedwa ndi 10-15%; kuchuluka kwa mchere kumawonjezeka ndi 10-15%; 4. Kuthamanga kwa ntchito kwawonjezeka ndi 10- 15%. 15%; 5. Kusiyana kwapakati pakati pa magawo a RO kwawonjezeka kwambiri.

7. Njira yosungira ya membrane element:

Kusungirako kwakanthawi kochepa ndi koyenera kumakina a reverse osmosis omwe atsekedwa kwa masiku 5-30.

Panthawiyi, chinthu cha membrane chimayikidwabe mu chotengera chokakamiza cha dongosolo.

1. Sambani reverse osmosis dongosolo ndi madzi chakudya, ndipo tcherani khutu kuchotsa kwathunthu mpweya dongosolo;
2. Pambuyo pa chotengera choponderezedwa ndi mapaipi okhudzana ndi madzi, kutseka ma valve oyenerera kuti gasi asalowe mu dongosolo;
3. Masiku 5 aliwonse Muzimutsuka kamodzi monga tafotokozera pamwambapa.

Kutetezedwa kwa nthawi yayitali

1. Kuyeretsa zinthu za nembanemba mu dongosolo;
2. Konzani madzi owumitsa ndi reverse osmosis opangidwa ndi madzi, ndikutsuka reverse osmosis system ndi madzi ophera;
3. Mukadzaza reverse osmosis system ndi madzi owumitsa, tsekani ma valve oyenerera Sungani madzi owumitsa mu dongosolo. Panthawiyi, onetsetsani kuti dongosolo ladzaza kwathunthu;
4. Ngati kutentha kwa dongosolo kuli kochepa kuposa madigiri 27, kuyenera kuyendetsedwa ndi madzi atsopano ophera tizilombo masiku 30 aliwonse; Ngati kutentha kuli kopitilira madigiri 27, iyenera kuyendetsedwa masiku 30 aliwonse. Bwezerani njira yothetsera sterilizing masiku 15 aliwonse;
5. Musanayambe kugwiritsa ntchito reverse osmosis system, tsitsani madzi owonjezera otsika kwa ola limodzi, kenako tsitsani makinawo ndi madzi opatsa mphamvu kwambiri kwa mphindi 5-10; mosasamala kanthu za kutsika kwapansi kapena kuthamanga kwapamwamba, madzi opangira madzi Ma valve onse okhetsa ayenera kukhala otseguka. Dongosololi lisanayambirenso ntchito yabwinobwino, yang'anani ndikutsimikizira kuti madzi amtunduwu alibe fungicides
