ʻEkolu kumu nui:
1. Keʻano kemika
ʻO ka ʻōlelo maʻalahi, ʻo ia ka hoʻohui ʻana i nā mea hana kemika i ka wai ʻino e ʻae i ka lepo i loko e hana a hiki ke wehe.
ʻO ke ʻano coagulation：TʻO ke kumu hana o ke ʻano coagulation ʻo ia ka hoʻohui ʻana i nā mea hana kemika i ka wai, e hoʻohui ai i nā ʻāpana liʻiliʻi i hoʻokuʻu ʻia a hana i nā flocs nui aʻe, a laila noho i lalo e ka umekaumaha. Hiki i kēia ʻano hana ke hoʻopau pono i ka chromaticity, bacteria, a me kekahi mea olaola mai ka wai. Eia nō naʻe, ua kaupalena ʻia kona hopena lapaʻau i nā mea i hoʻoheheʻe ʻia i ka wai, a ua maʻalahi ka hopena o ka mālama ʻana e ka fluctuations o ka wai wela a me ka waiwai pH.
ʻO ke ʻano hoʻokahe:Ue hīmeni i nā mea ʻokiʻoki (e like me ka chlorine, ozone) e hoʻoheheʻe i nā mea ʻawaʻawa i mea ʻino ʻole. He hopena maikaʻi ka Ozone a ʻaʻohe pollution lua, akā kiʻekiʻe ke kumukūʻai; Hoʻohana mau ʻia ka Chlorine a kūpono no ka mālama ʻana i ka wai ʻino i loaʻa ka phenol a me ka cyanide; He pōʻino iki ka hopena o ka ea a hoʻohana mau ʻia i ka wai ʻino kahi e maʻalahi ai nā mea haumia.
Ke ʻano uila: Hoʻohana ʻia ka uila e ʻae i nā mea haumia e hana ma ka ʻili electrode no ka wehe ʻana, a i kekahi manawa hoʻohui ʻia ka sodium chloride e hoʻomaikaʻi i ka hopena. He hopena maikaʻi kēia ʻano hana, akā ʻike ʻia kona mau hemahema: ma kekahi ʻaoʻao, hoʻopau nui ia i ka uila a loaʻa nā kumukūʻai kiʻekiʻe; Ma ka ʻaoʻao ʻē aʻe, hiki mai kekahi mau ʻaoʻao ʻaoʻao i ka wā o ke kaʻina hana, e alakaʻi ana i ka pollution lua.
2. Ka Hana Kino
E hoʻokaʻawale i nā haumia paʻa mai ka wai ma o nā ʻano kino.
Hoʻohana ke ʻano kānana i ka media kānana me nā micropores (e like me nā kānana microporous) e hoʻopaʻa i nā mea paʻa i ka wai.
ʻO ke kānāwai sedimentation ʻo ia ka hoʻohana ʻana i ka umekaumaha e ʻae ai i nā ʻāpana kaumaha i hoʻokuʻu ʻia i loko o ka ʻōpala e noho maoli i lalo o ka wai.
Hoʻokomo ʻia ke ʻano o ka lele ʻana o ka ea i ka nui o nā ʻōpū liʻiliʻi i loko o ka wai, e hoʻopili ai lākou i nā ʻāpana haumia a hana i kahi kino lana me ka haʻahaʻa haʻahaʻa ma mua o ka wai. A laila, piʻi aʻe i ka ʻili o ka wai ma o ka buoyancy a hoʻoneʻe ʻia e nā mea ʻōpala.
He maʻalahi a maʻalahi kēia mau ʻano hana, akā ʻaʻole hiki iā lākou ke wehe i nā mea haumia i hoʻoheheʻe ʻia i ka wai a loaʻa nā palena i kā lākou hoʻohana.
3. Photocatalytic oxidation 'enehana
Ma ka hoʻohana ʻana i nā kukui ultraviolet a me nā mea hoʻokahe (e like me ka hydrogen peroxide), hiki ke hoʻopau loa i nā mea haumia (e like me nā polychlorinated biphenyls).
Aia kekahi ʻano i kapa ʻia ʻo 'photocatalytic Fenton', hiki iā ia ke hana wikiwiki i ka nui o nā mea hana a me ka hoʻoheheʻe maikaʻi ʻana i nā mea ola ma lalo o ka hana hui o nā kukui a me nā ion hao.
ʻO kekahi ala ʻē aʻe, ʻo ia ka hoʻohui ʻana i nā mea semiconductor photosensitive (e like me ka titanium dioxide), ka mea e hoʻohua ai i nā radical manuahi e hoʻoheheʻe nui ʻia ma lalo o ka mālamalama māmā, e hoʻoheheʻe loa i nā mea haumia i nā mea ʻino ʻole e like me ke kalapona a me ka wai. Loaʻa i kēia ala ka mana nui no ka mālama ʻana i nā mea haumia recalcitrant.
