1. Kev kho ua ntej ntawm cov resin tshiab:
Vim muaj ntau yam xws li kev thauj mus los thiab kev khaws cia, nws yooj yim rau cov resin tshiab kom lub cev qhuav dej. Nws tuaj yeem kuaj pom ntawm qhov muag liab qab thiab hnov. Nyob rau hauv cov xwm txheej zoo li no, txhawm rau kom tsis txhob muaj cov resin los ntawm kev sib cuag nrog dej thiab lwm cov kua dej rov ua dua tshiab thiab ua rau cov khoom pov tseg tsis tsim nyog, nws yog ib qho tsim nyog yuav tsum tau tsau cov khoom no hauv 8% dej ntsev rau li 16 teev ( stirring nquag thaum soaking ). , kom cov resin tuaj yeem nthuav dav thiab yaug nrog dej huv kom txog thaum tsis muaj ntsev tsw ntxhiab ua ntej siv. Yog tias tsis muaj qhov tshwm sim zoo li no, cov resin tsis tas yuav tsum tau kho ua ntej.
2. Resin filling:
Resin filling qhov siab ntawm cov khoom siv hauv tsev sib xyaw yog 5 (6) 00mm rau cation resin thiab 10 (2) 00mm rau anion resin. Hauv cov xwm txheej tsis zoo (xws li thaum cation resin yog sodium hom thiab anion resin yog hom tshuaj chlorine), qhov siab ntawm cation resin yuav tsum tsis txhob siab tshaj qhov nruab nrab qhov hluav taws xob, tab sis yuav tsum tsis txhob qis dua 5cm. Qhov sib piv ntawm Yin Yang resin yog 2: 1 (los yog 1.5: 1). Cation exchange resin nyob rau hauv qab thiab anion txauv resin nyob rau sab saum toj.
3. Resin flushing:
Tom qab cov resin loaded rau hauv lub exchanger, rov qab ntxuav lub resin txheej nrog dej huv kom txog thaum lub effluent yog ntshiab, tsw, thiab tsis muaj zoo resin hais. Siv cov tshuaj 4-5% HCl uas yog kwv yees li ob zaug ntawm qhov ntim ntawm cov resin, dhau los ntawm cov txheej txheem resin ntawm tus nqi ntws ntawm 2m / h. Tom qab muab tso rau hauv tag nrho, tsau rau 4-8 teev, ntws cov kua qaub, thiab yaug nrog dej huv kom txog thaum cov dej ntws tawm nruab nrab, nrog cov dej ntws ntws ntawm 10-20 m / h. Siv cov tshuaj 2-5% NaOH uas yog kwv yees li ob npaug ntawm qhov ntim ntawm cov resin, qhia thiab tsau nws siv txoj kev ntxiv HCl tov raws li tau piav qhia saum toj no. Tshem tawm cov tshuaj alkaline thiab yaug nrog dej huv kom txog thaum cov kua dej tsis zoo. Cov dej ntws ntws ntws zoo ib yam li saum toj no. Yog tias cov kua qaub thiab alkali tuaj yeem rov ua dua 2-3 zaug, cov nyhuv yuav zoo dua.
4. Yin Yang cob sib tov:
Tom qab dej ntws tawm, qhib lub qhov dej hauv qab thiab sab sauv tawm, pib lub twj tso kua mis nruab nrab (rov qab ua kom cov txheej txheej resin loosen), thiab thaum cov dej ntim hauv kem tawm mus rau {{0}}mm saum toj no. resin txheej, kaw qhov nruab nrab twj tso kua mis thiab inlet valve; 2. Qhib qhov me me ntawm qhov tso pa tawm, qhib thiab tswj qhov ntim ntawm qhov nqus ntawm lub valve (kev siv lub siab yog 0.1-0.15Mpa), saib xyuas lub suab nrov thiab sib xyaw ntawm cov resin nyob rau sab sauv thiab sab tsom iav , kom cov xim ntawm lub sab sauv thiab qis resins zoo ib yam. Lub sij hawm noj yog feem ntau 10-15 feeb; 3. Tom qab sib tov, kaw lub qhov nqus dej thiab tso pa tawm, tom qab ntawd qhib lub valve sab saud, lub twj tso kua mis nruab nrab, thiab cov pa tawm qis qis (kom cov resin tuaj yeem kho sai sai thiab tiv thaiv cov resin los ntawm cov txheej txheem rov ua dua thaum lub sijhawm ua haujlwm). Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los tiv thaiv cov resin tawm ntawm cov dej saum npoo av, txwv tsis pub cov npuas yuav raug tsim los ntawm cov resins, uas yuav cuam tshuam rau cov effluent zoo ntawm lub txaj sib xyaw (yog tias qhov sib xyaw ua haujlwm tsis zoo, kev sib xyaw ua haujlwm. tuaj yeem rov ua dua).
