Ko te Electrocoagulation (EC) he tukanga e whakamahi ana i te iahiko hiko hei tango i ngā poke mai i te wai para. Kei roto ko te whakamahinga o te pūhiko hiko dc hei whakarewa i ngā irahiko patunga tapu, kātahi ka tukuna ngā iona konganuku e whakakotahi ana me ngā poke. Kua rongonui tēnei tikanga nā tōna whai huatanga, tōna āhua pai ki te taiao, me tōna whānuitanga ki te rongoā i ngā momo wai para.
Ngā Mātāpono o te Whakakorikori Hiko
I roto i te electrocoagulation, ka tukuna he iahiko mā roto i ngā irahiko whakarewa kua rumakina ki roto i te wai para. Ka rewa te anode (irahiko pai), ka tukuna ngā katione whakarewa pērā i te konumohe, te rino rānei ki roto i te wai. Ka tauhohe ēnei katote whakarewa ki ngā poke i roto i te wai, ka hanga he hauwaiwai kore-rewa ka kohikohi, ā, ka taea te tango ngāwari. Ka whakaputa te cathode (irahiko kino) i te hau hauwai, e āwhina ana ki te whakatere i ngā matūriki kua rewa ki te mata hei tango.
Ka taea te whakarāpopoto i te tukanga whānui i roto i ngā mahi e whai ake nei:
Te hikohiko: ka tukuna he hiko hiko DC ki ngā irahiko, ka memeha te anode, ka tukuna ngā katote konganuku.
Te Whakapūpū: Ka whakakorea e ngā katote konganuku kua tukuna ngā utu o ngā matūriki iri me ngā poke rewa, ka hua ake ai te hanganga o ngā mea whakahiato nui ake.
Te Whakarewatanga: Ka piri ngā mirumiru hau hauwai e puta mai ana i te katote ki ngā mea whakahiato, ka mānu ai ki te mata.
Te Wehewehenga: Ka tangohia te paru e mānu ana mā te tango wai, ko te paru kua tau ka kohia mai i te raro.
Ngā Painga o te Pūnaha Hiko DC i roto i te Whakakorikori Hiko
Whai huatanga: mā te hiko hiko ā-auau ka taea te whakahaere tika i te iahiko me te ngaohiko e whakamahia ana, ka arotau i te whakarewanga o ngā irahiko me te whakarite kia pai te whakapūmau i ngā poke.
Ngāwari noa iho: He tino māmā te whakatakotoranga mō te electrocoagulation mā te whakamahi i te pūnaha hiko DC, kei roto ko te pūnaha hiko, ngā irahiko, me te rūma tauhohenga.
He Ātaahua ki te Taiao: Kāore i rite ki te whakapūnga matū, kāore e hiahiatia he tāpiri matū o waho mō te whakapūnga hiko, ka whakaiti i te tūponotanga o te parahanga tuarua.
Ngā Āhuatanga maha: Ka taea e te EC te rongoā i te whānuitanga o ngā poke, tae atu ki ngā konganuku taumaha, ngā matū waro, ngā totoka i whakatārewatia, tae atu ki ngā mate urutā.
Ngā Whakamahinga o te Whakakorikori Hiko i roto i te Maimoatanga Wai Para
Wai Para Ahumahi: He tino whai hua te electrocoagulation ki te rongoā i ngā wai para ahumahi kei roto ngā konganuku taumaha, ngā tae, ngā hinu, me ētahi atu poke matatini. Ka whai hua ngā ahumahi pēnei i ngā kakahu, te whakakikorua hiko, me ngā rongoā i te kaha o te EC ki te tango i ngā matū paitini me te whakaiti i te hiahia hāora matū (COD).
Wai Para o te Tāone: Ka taea te whakamahi i te EC hei tikanga maimoatanga tuatahi, tuarua rānei mō te wai para o te tāone, hei āwhina i te tango i ngā totoka i whakatārewatia, ngā phosphates, me ngā pathogens. Ka whakarei ake i te kounga whānui o te wai kua tukatukahia, kia pai ai mō te tuku, te whakamahi anō rānei.
Te Rerenga Ahuwhenua: Ka taea e te EC te rongoā i ngā rerenga ahuwhenua kei roto ngā patupatu, ngā maniua, me ngā mea rauropi. Ka āwhina tēnei tono ki te whakaiti i te pānga o ngā mahi ahuwhenua ki ngā wai tata.
Maimoatanga Wai Ua: Ka taea te whakamahi i te EC ki ngā wai e rere ana hei tango i ngā paru, ngā konganuku taumaha, me ētahi atu poke, kia kore ai e uru ki ngā wai tūturu.
Ngā Tawhā Whakahaere me te Arotautanga
Ko te whai huatanga o te electrocoagulation e whakawhirinaki ana ki ētahi tawhā mahi, tae atu ki:
Te Kiato o te Au: Ka pā te nui o te au e whakamahia ana mō ia wāhanga horahanga o te irahiko ki te tere o te tukunga katote whakarewa me te whai huatanga whānui o te tukanga. Ka taea e ngā kiato o te au teitei ake te whakanui ake i te whai huatanga o te maimoatanga engari ka arahi pea ki te nui ake o te whakapaunga pūngao me te pakaru o te irahiko.
Rauemi Irahiko: Ko te whiriwhiri i te rauemi irahiko (ko te konumohe, ko te rino rānei) ka pā ki te momo me te whai huatanga o te whakapūtātanga. Ka whiriwhiria ngā rauemi rerekē i runga i ngā poke motuhake kei roto i te wai para.
pH: Ka pā te pH o te wai para ki te wairewatanga me te hanganga o ngā hauwaiwai whakarewa. Mā ngā taumata pH tino pai ka whakarite kia pai te whakapūmautanga me te pumau o ngā matū kua hangaia.
Whirihoranga Irahiko: Ka pā te whakaritenga me te mokowā o ngā irahiko ki te tohatoha o te papa hiko me te ōritetanga o te tukanga maimoatanga. Mā te whirihoranga tika ka whakarei ake i te whakapā i waenga i ngā katote whakarewa me ngā poke.
Wā Tauhohenga: Ka pā te roa o te whakapūngao hiko ki te nui o te tango i ngā poke. Mā te wā tauhohenga rawaka ka taea te whakapūngao me te wehenga o ngā poke.
Ngā Wero me ngā Aronga o te Ao
Ahakoa ōna painga, he maha ngā wero kei mua i te electrocoagulation:
Te Whakapaunga Irahiko: Nā te āhua patunga tapu o te anode ka āta whakamahia, ka hiahiatia he whakakapinga, he whakahoutanga rānei i ia wā.
Te Whakapaunga Pūngao: Ahakoa e taea ai e te pūtake hiko DC te whakahaere tika, ka nui te whakapaunga pūngao, inā koa mō ngā mahi tauine nui.
Te Whakahaere Para: Ka puta te para i roto i te tukanga e tika ana kia whakahaerea tika, kia whakakorea hoki, ā, ka nui ake ngā utu whakahaere.
Ko te whāinga o ngā rangahau me ngā whanaketanga ā muri ake nei ko te whakatika i ēnei wero mā te:
Te Whakapai Ake i ngā Rauemi Irahiko: Te whakawhanake i ngā rauemi irahiko pakari ake, whai hua ake hoki hei whakaiti i te whakapaunga me te whakarei ake i te mahi.
Te Arotau i te Pūngao Hiko: Te whakamahi i ngā tikanga pūngao matatau, pērā i te hiko DC pāorooro, hei whakaiti i te whakapaunga pūngao me te whakapai ake i te whai huatanga o te maimoatanga.
Te Whakapai Ake i te Whakahaerenga o te Para: Te auaha i ngā tikanga mō te whakaiti me te whakanui i te uara o te para, pērā i te huri i te para hei hua taha whai hua.
Hei whakamutunga, he mea nui te hiko DC i roto i te electrocoagulation mō te maimoatanga wai para, e tuku ana i tētahi otinga whai hua, pai mō te taiao, me te maha o ngā whakamahinga mō te tango i ngā poke. Me ngā whanaketanga me ngā whakapainga tonu, kua rite te electrocoagulation hei tikanga whai hua me te pumau ake mō te aro atu ki ngā wero maimoatanga wai para o te ao.
