Ke holomua nei ka noiʻi ʻana, ua ulu nui ka ʻenehana no ka mālama ʻana i ka wai ʻino ʻoihana me ka hao-carbon microelectrolysis. Ke ulu nui nei ka ʻenehana Microelectrolysis i ka mālama ʻana i ka wai ʻōpala ʻoihana recalcitrant a ua loaʻa ka noi ākea i ka hana ʻenekinia.
ʻO ke kumu o ka microelectrolysis he mea maʻalahi; hoʻohana ʻo ia i ka ʻino o nā metala e hana i nā cell electrochemical no ka mālama ʻana i ka wai. Ke hoʻohana nei kēia ʻano hana i nā ʻōpala hao ʻōpala ma ke ʻano he kumu waiwai, ʻaʻole koi i ka ʻai ʻana i nā kumuwaiwai uila, a no laila, hoʻokomo ʻia ka manaʻo o "ka mālama ʻana i ka ʻōpala me ka ʻōpala." ʻO ke kikoʻī, i loko o ke kolamu electrolytic i loko o ke kaʻina microelectrolysis, hoʻohana pinepine ʻia nā mea e like me nā ʻōpala hao a me nā kalapona i hoʻāla ʻia e like me nā mea hoʻopiha. Ma o nā hopena kemika, hana ʻia nā ion Fe2+ hoʻemi ikaika, hiki ke hōʻemi i kekahi mau mea i loko o ka wai ʻōpala i loaʻa nā waiwai oxidative.
Eia hou, hiki ke hoʻohana ʻia ʻo Fe(OH)2 no ka coagulation i ka mālama ʻana i ka wai, a loaʻa ka carbon activated i nā mana adsorption, me ka wehe pono ʻana i nā pūhui organik a me nā microorganisms. No laila, ʻo ka microelectrolysis e pili ana i ka hoʻokumu ʻana i kahi au uila nāwaliwali ma o ka hao-carbon electrochemical cell, kahi e hoʻoulu ai i ka ulu a me ka metabolism o nā microorganisms. ʻO ka pōmaikaʻi koʻikoʻi o ka hana mālama wai electrolysis kūloko ʻaʻole ia e hoʻopau i ka ikehu a hiki i ka manawa like ke wehe i nā mea haumia a me ka waihoʻoluʻu mai ka wai ʻino i ka wā e hoʻomaikaʻi ai i ka biodegradability o nā mea recalcitrant. Hoʻohana maʻamau ka ʻenehana mālama wai microelectrolysis ma ke ʻano he pretreatment a i ʻole ke ʻano hoʻohui i hui pū ʻia me nā ʻenehana mālama wai ʻē aʻe e hoʻomaikaʻi ai i ka mālama ʻana a me ka biodegradability o ka wai ʻino. Eia nō naʻe, loaʻa iā ia nā pōʻino, ʻo ka drawback nui ʻo ia ka lohi o ka pane ʻana, ka hoʻopaʻa ʻana o ka reactor, a me nā pilikia i ka mālama ʻana i ka wai ʻino nui.
I ka hoʻomaka ʻana, ua hoʻohana ʻia ka ʻenehana microelectrolysis hao-carbon i ka mālama ʻana i ka waihoʻoluʻu a me ka paʻi ʻana i ka wai ʻino, e loaʻa ana nā hopena maikaʻi. Hoʻohui ʻia, ua mālama ʻia ka noiʻi nui a me ka noi ʻana i ka mālama ʻana i ka wai ʻōpala waiwai nui mai ka hana pepa, lāʻau lapaʻau, coking, high-salinity organic wastewater, electroplating, petrochemicals, pesticide-containing wastewater, a me ka wai ʻōpala i loaʻa i ka arsenic a me ka cyanide. I ka mālama ʻana i ka wai ʻōpala organik, ʻaʻole wehe wale ka microelectrolysis i nā pūhui organik akā e hōʻemi ana hoʻi i ka COD a hoʻonui i ka biodegradability. Hoʻomaʻamaʻa ia i ka wehe ʻana o nā pūʻulu oxidative i loko o nā pūhui organik ma o adsorption, coagulation, chelation, a me electro-deposition, e hana ana i nā kūlana kūpono no ka mālama hou ʻana.
Ma nā noi kūpono, ua hōʻike ka iron-carbon microelectrolysis i nā pōmaikaʻi nui a me nā manaʻo hoʻohiki. Eia nō naʻe, ʻo nā pilikia e like me ka clogging a me ka hoʻoponopono pH e kaupalena i ka hoʻomohala hou ʻana o kēia kaʻina hana. Pono nā ʻoihana kaiapuni e hana hou i ka noiʻi ʻana e hana i nā kūlana maikaʻi aʻe no ka hoʻohana ʻana i ka ʻenehana microelectrolysis hao-carbon i ka mālama ʻana i ka wai ʻino ʻoihana nui.
