Resin pretreatment:
Kev lag luam qib resins yog residual inert cov kuab tshuaj, yog li ua ntej siv, raws li qhov xav tau ntawm daim ntawv thov daim teb, kom ua tiav qhov sib txawv qhov tob pretreatment: nyob rau hauv lub extractor, ntxiv 10-20 cm siab tshaj li resin txheej ntawm ethanol soaked rau {{ 1}} teev, thiab tom qab ntawd muab cov kua ntxuav, rau ib txheej txheem rho tawm. Siv tib txoj kev los ntxuav ntau zaus kom txog thaum lub qhov hluav taws xob ntxuav cov kua dej ntxiv 3 zaug ntawm cov dej hauv lub raj kuaj tsis pom huab, thiab tom qab ntawd yaug nrog dej huv kom txog thaum tsis muaj qhov pom tseeb ethanol tsw, koj tuaj yeem siv rau kev siv dav dav. siv.
Resin enhanced regeneration kev kho mob:
Thaum cov resin feem ntau siv rau qee lub sijhawm, lub peev xwm adsorption txo qis heev lossis muaj kuab paug hnyav, nws yuav tsum tau ntxiv dag zog rau kev kho dua tshiab, txoj kev yog ntxiv 3-5% hydrochloric acid tov 10-20 cm. siab tshaj cov txheej resin rau soak rau 2-4 teev, thiab tom qab ntawd yaug nrog tib qhov concentration 5-7 zaug ntawm qhov ntim ntawm hydrochloric acid tov, thiab tom qab ntawd yaug nrog dej ntshiab. Kom txog rau thaum PH tus nqi ntawm lub qhov hluav taws xob ntxhua khaub ncaws yog nruab nrab, ces tsau rau hauv 5% sodium hydroxide tov raws li cov txheej txheem saum toj no rau 2-4 teev, thiab yaug nrog tib txoj kev kom txog thaum 5-7 zaus ntawm sodium hydroxide tov, thiab tom qab ntawd yaug nrog dej kom txog thaum tus nqi PH effluent nruab nrab, koj tuaj yeem muab rov qab siv dua. Resin reinforcement regeneration yuav tsum tau ua raws li qib ntawm kev ua qias tuaj, raws li qhov tsim nyog, qhov concentration thiab ntau npaum li cas ntawm cov kua qaub thiab alkali, tab sis kuj raws li cov ntaub ntawv siv tiag tiag los tshawb txog txoj cai tsim dua tshiab, sau cov kev paub dhau los, tsim cov txheej txheem rov tsim dua tshiab, thiab txuas ntxiv mus. kev pab cuam lub neej ntawm cov resin.
