ʻenehana mālama wai Microelectrolysis

I ka holomua ʻana o ka noiʻi, ua lilo ka ʻenehana no ka mālama ʻana i ka wai ʻino ʻoihana me ka hoʻohana ʻana i ka microelectrolysis hao-kalapona i mea oʻo. Ke piʻi nei ka ʻenehana Microelectrolysis i ka kaulana i ka mālama ʻana i ka wai ʻino ʻoihana recalcitrant a ua loaʻa ka hoʻohana ākea i ka hana ʻenekinia.

He maʻalahi loa ke kumumanaʻo o ka microelectrolysis; hoʻohana ia i ka pala o nā metala e hana i nā cell electrochemical no ka mālama ʻana i ka wai ʻino. Hoʻohana kēia ʻano hana i nā ʻōpala hao ʻōpala ma ke ʻano he mea maka, ʻaʻole pono e hoʻohana i nā kumuwaiwai uila, a no laila, hoʻokomo ia i ka manaʻo o ka "mālama ʻana i ka ʻōpala me ka ʻōpala." Ma ke ʻano kikoʻī, ma ke kolamu electrolytic o loko o ke kaʻina hana microelectrolysis, hoʻohana pinepine ʻia nā mea e like me nā ʻōpala hao ʻōpala a me ke kalapona i hoʻāla ʻia e like me nā mea hoʻopiha. Ma o nā hopena kemika, hoʻoulu ʻia nā ion Fe2+ hoʻemi ikaika, hiki ke hoʻemi i kekahi mau ʻāpana i loko o ka wai ʻino nona nā waiwai oxidative.

Eia kekahi, hiki ke hoʻohana ʻia ʻo Fe(OH)2 no ka coagulation i ka mālama ʻana i ka wai, a he hiki ke adsorption ke kalapona i hoʻāla ʻia, e wehe pono ana i nā hui organik a me nā microorganism. No laila, pili ka microelectrolysis i ka hana ʻana o kahi au uila nāwaliwali ma o kahi cell electrochemical iron-carbon, kahi e hoʻoulu ai i ka ulu ʻana a me ka metabolism o nā microorganism. ʻO ka pōmaikaʻi nui o ke ʻano mālama wai electrolysis kūloko ʻaʻole ia e hoʻopau i ka ikehu a hiki i ka manawa like ke wehe i nā mea haumia like ʻole a me ke kala mai ka wai hoʻoneʻe ʻoiai e hoʻomaikaʻi ana i ka biodegradability o nā mea recalcitrant. Hoʻohana pinepine ʻia ka ʻenehana mālama wai Microelectrolysis ma ke ʻano he pretreatment a i ʻole ke ʻano hoʻohui me nā ʻano hana mālama wai ʻē aʻe e hoʻonui i ka mālama ʻana a me ka biodegradability o ka wai hoʻoneʻe. Eia nō naʻe, he mau hemahema nō hoʻi, me ka drawback nui ʻo ia ka lohi o ka pane ʻana, ka pale ʻana o ka reactor, a me nā pilikia i ka mālama ʻana i ka wai hoʻoneʻe kiʻekiʻe.

I ka wā mua, ua hoʻohana ʻia ka ʻenehana microelectrolysis hao-kalapona i ka mālama ʻana i ka hoʻoluʻu ʻana a me ka paʻi ʻana i ka wai hoʻoneʻe, a loaʻa nā hopena maikaʻi. Eia kekahi, ua hana ʻia nā noiʻi nui a me nā noi ʻana i ka mālama ʻana i ka wai hoʻoneʻe waiwai organik mai ka hana pepa, nā lāʻau lapaʻau, ka coking, ka wai hoʻoneʻe organik salinity kiʻekiʻe, ka electroplating, nā petrochemicals, ka wai hoʻoneʻe i loaʻa ka pesticide, a me ka wai hoʻoneʻe i loaʻa ka arsenic a me ka cyanide. I ka mālama ʻana i ka wai hoʻoneʻe organik, ʻaʻole wale ka microelectrolysis e wehe i nā hui organik akā e hōʻemi pū i ka COD a hoʻonui i ka biodegradability. Hoʻomaʻalahi ia i ka wehe ʻana i nā hui oxidative i loko o nā hui organik ma o ka adsorption, coagulation, chelation, a me ka electro-deposition, e hana ana i nā kūlana maikaʻi no ka mālama hou ʻana.

Ma nā noi hana, ua hōʻike ka microelectrolysis hao-kalapona i nā pono koʻikoʻi a me nā manaʻolana hoʻohiki. Eia nō naʻe, ʻo nā pilikia e like me ke kāpili ʻana a me ka hoʻoponopono pH e kaupalena i ka hoʻomohala hou ʻana o kēia kaʻina hana. Pono nā loea kaiapuni e hana i nā noiʻi hou aku e hana i nā kūlana ʻoi aku ka maikaʻi no ka hoʻohana ʻana i ka ʻenehana microelectrolysis hao-kalapona i ka mālama ʻana i ka wai ʻino ʻoihana nui.
