Nuclear sewage haina kuenzana nemarara enyukireya, mvura, tsvina yenyukireya inokuvadza zvakanyanya, kusanganisira tritium, kusanganisira 64 marudzi enyukireya radioactive zvinhu. Mushure mekunge mvura yakasvibiswa yenyukireya yapinda munharaunda yeMarine, inotanga kutakurwa nemhepo yegungwa uye inopararira kumakungwa akasiyana.
Pamusoro pezvo, icharamba ichifambiswa kuburikidza neMarine ecosystem, sekuparadzirwa kwecheni yechikafu, uye inogona zvakare kupinda mumuviri wemunhu kuburikidza nekudyiwa kweveruzhinji chikafu chemugungwa, nekudaro zvichiunza zvimwe zvinokanganisa paMarine ecosystem kana hutano hwevanhu. Zvinoenderana nekutarisa kwakapfuura kwetsaona yenyukireya yeFukushima, kusvibiswa kwakawanda kuchaenda kumabvazuva uyezve kuyambuka Pacific Ocean.
Chikamu chidiki chezvinosvibisa izvi chichapinda kumaodzanyemba kwakadziva kumadokero kuburikidza neWest Pac iic membrane mvura. Nekuda kwekuti zvinhu zvine radioactive mumvura yetsvina yenyukireya zvine mwaranzi zvine mwaranzi uye zvimiro zvadzo zvakadzikama zvakanyanya, mabatirwo azvino emvura yakaraswa yenyukireya ndeyekutarisisa zvinhu zvine radioactive kuburikidza nehunyanzvi nzira dzehunyanzvi, uyezve kuburitsa tsvina inosangana neradioactivity standard.
Parizvino, nzira dzinoshandiswa zvakanyanya dzenyukireya dzekuchenesa mvura dzinosanganisira dzinotevera:
(1)Kunaya kwemvura: Iyo nzira yekunaya ndeyekuwedzera mvura inonaya kumvura yetsvina yenyukireya, uye kupindirana kwekunaya kwemakemikari anoumbwa uye zvinhu zvine radioactive mune inonaya mvura inoshandiswa kuzadzisa chinangwa chekudzikisa zviri mukati meradioactive element mumvura ine tsvina yenyukireya. Parizvino, anowanzo shandiswa maindasitiri precipitants anonyanya kusanganisira aluminium uye iron precipitants, lime soda precipitants uye phosphate precipitants.
(2)Adsorption nzira: Adsorption nzira inzira yekushandisa adsorbents adsorb radioactive zvinhu, inova yemuviri kurapa nzira. Nekuda kweiyo yakagadziridzwa pore chimiro uye yakakura chaiyo nzvimbo, iyo adsorbent ine yakasimba adsorption kugona. Parizvino, adsorbents anowanzo shandiswa ari activated kabhoni, zeolite uye zvichingodaro.
(3)Ion kuchinjanisa nzira: Iyo musimboti weiyoni yekutsinhana nzira ndeye kushandisa ion exchangers kuita ion kuchinjana nemvura yenyukireya tsvina, kuitira kubvisa radioactive ion exchange mumvura yenyukireya tsvina. Iwo maion eradioactive ari mumvura yetsvina yenyukireya anowanzo cations, saka mapoka anochajirwa zvakanaka ari muioni exchanger anogona kuchinjana nemaayoni eradioactive, uye maion eradioactive anogona kuchinjana kuita exchanger. Anowanzo shandiswa ion exchangers akakamurwa kuita organic uye inorganic ion exchangers mapoka maviri, organic ion exchangers anonyanya akasiyana ion exchange resin, inorganic ion exchangers ndeye artificial zeolite, vermiculite zvichingodaro.
