Nuclear dej phwj tsis sib npaug ntawm cov pov tseg nuclear, dej, dej phwj hauv nuclear muaj kev phom sij ntau dua, suav nrog tritium, suav nrog 64 hom hluav taws xob nuclear. Tom qab cov dej tsis huv nuclear nkag mus rau hauv Marine ib puag ncig, nws yog thawj zaug thauj los ntawm dej hiav txwv tam sim no thiab yuav kis mus rau cov dej hiav txwv sib txawv.
Tsis tas li ntawd, nws tseem yuav kis tau los ntawm Marine ecosystem, xws li kev nthuav tawm ntawm cov khoom noj khoom haus, thiab tseem tuaj yeem nkag mus rau tib neeg lub cev los ntawm kev noj cov nqaij nruab deg, yog li coj qee yam cuam tshuam rau Marine ecosystem lossis tib neeg kev noj qab haus huv. Raws li kev soj ntsuam yav dhau los ntawm Fukushima nuclear kev sib tsoo, feem ntau ntawm kev sib kis yuav mus rau sab hnub tuaj thiab tom qab ntawd hla dej hiav txwv Pacific.
Ib feem me me ntawm cov pa phem no yuav nkag mus rau sab qab teb sab hnub poob mus rau sab hnub poob Pac ific membrane dej. Vim hais tias cov khoom siv hluav taws xob hauv cov dej khib nyiab nuclear yog cov xov tooj cua muaj zog thiab lawv lub cev muaj zog ruaj khov, kev kho tam sim no ntawm cov dej khib nyiab nuclear yog tsom rau cov khoom siv hluav taws xob los ntawm cov txheej txheem tshwj xeeb, thiab tom qab ntawd tso cov kua pov tseg uas ua tau raws li cov qauv siv hluav taws xob.
Tam sim no, kev siv dav siv hauv kev kho dej khib nyiab nuclear feem ntau suav nrog cov hauv qab no:
(1)Txoj kev los nag: Txoj kev nag lossis daus yog ntxiv tus neeg ua haujlwm nag lossis daus rau cov dej khib nyiab nuclear, thiab cov tshuaj tiv thaiv nag lossis daus ntawm cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv hluav taws xob hauv cov neeg ua dej nag yog siv los ua kom tiav lub hom phiaj ntawm kev txo cov ntsiab lus ntawm cov khoom siv hluav taws xob hauv cov dej khib nyiab nuclear. Tam sim no, feem ntau siv cov precipitants feem ntau suav nrog txhuas thiab hlau precipitants, txiv qaub soda precipitants thiab phosphate precipitants.
(2)Txoj kev adsorption: Txoj kev adsorption yog ib txoj hauv kev siv cov adsorbents rau adsorb radioactive cov ntsiab lus, uas yog ib txoj kev kho lub cev. Vim yog cov qauv tsim pore thiab thaj chaw loj tshwj xeeb, cov adsorbent muaj peev xwm adsorption muaj zog. Tam sim no, feem ntau siv adsorbents yog activated carbon, zeolite thiab lwm yam.
(3)Txoj kev sib pauv ion: Lub hauv paus ntsiab lus ntawm kev sib pauv ion yog siv ion exchangers los ua ion pauv nrog cov dej khib nyiab nuclear, thiaj li tshem tawm cov hluav taws xob ion pauv hauv cov dej khib nyiab. Cov hluav taws xob ions uas muaj nyob rau hauv cov dej khib nyiab nuclear feem ntau yog cations, yog li cov pab pawg muaj txiaj ntsig zoo hauv cov ion exchanger tuaj yeem sib pauv nrog cov xov tooj cua cations, thiab cov hluav taws xob ions tuaj yeem hloov pauv mus rau hauv lub exchanger. Feem ntau siv ion exchangers tau muab faib ua cov organic thiab inorganic ion exchangers ob pawg, cov organic ion exchangers feem ntau yog ntau yam ion pauv resins, inorganic ion exchangers yog dag zeolite, vermiculite thiab lwm yam.
