Ka wehe ʻana i ka haumia
ʻO nā huahana ʻoihana o ka resin exchange ion pinepine ka hapa o ka polymer haʻahaʻa a me ka monomer reactive ʻole, a me nā impurities inorganic e like me ka hao, kēpau a me ke keleawe. Ke hoʻopili ka resin me ka wai, ʻakika, alkali a i ʻole nā haʻina ʻē aʻe, e hoʻoili ʻia nā mea i luna i loko o ka hopena, e hoʻololi ana i ka maikaʻi o ka wai effluent. No laila, pono e hana i ka kēpau hou ma mua o ka hoʻohana. ʻO ka maʻamau, hoʻohana ʻia ka wai e hoʻonui i ke kēpau, a laila, hiki ke wehe ʻia nā impurities inorganic (ʻo ka nui o nā hui hao) e 4-5% dilute hydrochloric acid, a hiki ke hoʻoneʻe ʻia nā impurities ʻupena e 2-4% dilute sodium hydroxide hoʻonā. Inā hoʻohana ʻia ia i ka hoʻomākaukau lāʻau lapaʻau, pono e pulu i ka ethanol.
Mālama Hana Hoʻolālā Periodic
I ka hoʻohana ʻana o ka kēpau, pono e pale i ka hoʻopili ʻana me ka hoʻohaumia o ka aila, microorganism moleola ʻokanika, oxidant ikaika a me nā metala ʻē aʻe (e like me ka hao, keleawe, a me nā mea ʻē aʻe) i mea e hōʻalo ai i ka hōʻemi ʻana i ka hiki ke hoʻololi i ka ion a i ʻole ka nalo ʻana i ka hana. No laila, pono e hoʻohana i ka kēpau me ka pololei ʻole e like me ke kūlana. Hiki ke hoʻoholo i ke ʻano hoʻouluulu e like me ke kūlana haumia a me nā kūlana. ʻO ka maʻamau, maʻalahi ka haumia o ke kēpau e haumia e Fe i ka palupalu ʻana e ka immersive acid hydrochloric, a laila hoʻokahe mālie, maʻalahi ka resion anion e haumia e nā meaola. Hiki ke pulu a holoi ʻia paha me 10% NaCl + 2-5% NaOH i ka hopena hoʻohuihui. Inā pono, hiki ke pulu i 1% hydrogen peroxide solution no kekahi mau minuke. ʻO nā mea ʻē aʻe, hiki iā ia ke hoʻohana i ka lāʻau acid-base alternate treatment, ka hoʻomaʻemaʻe bleaching, ka mālama ʻana i ka waiʻona a me nā ʻano sterilization like ʻole.
ʻO New Resin Pretreatment
Pretreatment o ke kēpau hou: i nā huahana ʻoihana o resin exchange resin, aia kekahi mau liʻiliʻi o nā oligomers a me nā monomers i komo ʻole i ka hopena, a loaʻa pū kekahi i nā haumia inorganic e like me ka hao, kēpau a me ke keleawe. Ke hoʻopili ka resin i ka wai, waikawa, alkali a i ʻole nā haʻina ʻē aʻe, e hoʻohuli ʻia nā mea i luna i loko o ka hopena, e hoʻopili ai i ka maikaʻi o ka effluent. No laila, pono e mālama mua ʻia ka resin hou ma mua o ka hoʻohana. ʻO ka maʻamau, e hoʻonui ka kēpau me ka wai, a laila hiki ke hemo i nā impurities inorganic (ʻo ka hapa nui o nā hui hao) e 4-5% dilute hydrochloric acid, a hiki ke hoʻoneʻe ʻia nā impurities ʻupena e 2-4% dilute sodium hydroxide solution e holoi i kahi kūlike ʻole.
