Tirohanga WhānuiKo te wai para hanga pepa e ahu mai ana i ngā tukanga whakaputa e rua, arā, te whakapūpū me te hanga pepa i roto i te umanga hanga pepa. Ko te whakapūpū he wehewehe i ngā muka mai i ngā rauemi mata o te tipu, te hanga pūpū, kātahi ka whakamakuku. Ka puta he nui o te wai para hanga pepa i tēnei tukanga; ko te hanga pepa he whakawaiwai, he hanga āhua, he pēhi, he whakamaroke i te pūpū hei hanga pepa. He ngāwari hoki tēnei tukanga ki te whakaputa wai para hanga pepa. Ko te wai para matua e puta ana i roto i te tukanga whakapūpū he wai pango me te wai whero, ā, ko te hanga pepa he wai mā te nuinga.
Ngā Āhuatanga Matua 1. He nui te wai para. 2. He nui ngā totoka iri i roto i te wai para, ko te nuinga he mangumangu, he muka, he whakakī me ngā tāpiringa. 3. He teitei te SS, te COD, te BOD me ētahi atu poke i roto i te wai para, he teitei ake te ihirangi COD i te BOD, ā, he pouri ake te tae.
Mahere maimoatanga me te otinga raruraru.1. Tikanga maimoatanga Ko te tikanga maimoatanga o nāianei e whakamahi ana i te huinga o te tukanga whakapūmau me te whakatō.
Te tukanga maimoatanga me te rere: Whai muri i te urunga o te wai para ki te pūnaha maimoatanga wai para, ka haere tuatahi mā te whatanga para hei tango i ngā paru nui ake, ka tomo ki te puna whatunga hei whakataurite, ka tomo ki te tāke whakapūmau, ka puta he tauhohenga whakapūmau mā te tāpiri i te polyaluminum chloride me te polyacrylamide. Whai muri i te urunga ki te whakapūmau, ka tangohia te SS me tetahi wāhanga o te BOD me te COD i roto i te wai para. Ka tomo te wai para ki te maimoatanga matū rua-wāhanga anaerobic me te aerobic hei tango i te nuinga o te BOD me te COD i roto i te wai. Whai muri i te tāke whakapūmau tuarua, kāore te COD me te chromaticity o te wai para e tutuki i ngā paerewa tukunga ā-motu. Ka whakamahia te whakapūmau matū hei whakapai ake i te maimoatanga kia taea ai e te wai para te tutuki i ngā paerewa tukunga, kia taea ai rānei te tutuki i ngā paerewa tukunga.
Ngā Raru me ngā Otinga Noa 1) Ka hipa te COD i te paerewa. Whai muri i te tukatuka i te wai para mā te maimoatanga matū koiora anaerobic me te aerobic, kāore te COD o te wai para e tutuki i ngā paerewa tukunga. Otinga: Whakamahia te kaihoko whakararu COD tino whai hua SCOD mō te maimoatanga. Tāpirihia ki te wai i roto i tētahi ōwehenga ka tauhohe mō te 30 meneti.
2) Ko te tae me te COD e hipa ana i te paerewa. Whai muri i te tukatuka i te wai para mā te maimoatanga matū koiora anaerobic me te aerobic, kāore te COD o te wai para e tutuki i ngā paerewa tukunga. Otinga: Tāpirihia te tango tae flocculation tino whai hua, whakaranua ki te tango tae tino whai hua, ā, hei whakamutunga, whakamahia te polyacrylamide mō te flocculation me te precipitation, te wehenga totoka-wai.
3) Te nui rawa o te hauota haukini Kāore e taea e te hauota haukini waipara te whakatutuki i ngā whakaritenga tukunga o nāianei. Otinga: Tāpirihia te tango hauota haukini, whakaohokia, whakapūhau rānei, ka whakaranu, ka tauhohe mō te 6 meneti. I roto i te mira pepa, ko te hauota haukini waipara he tata ki te 40ppm, ā, ko te paerewa tukunga hauota haukini ā-rohe kei raro iho i te 15ppm, kāore e taea te whakatutuki i ngā whakaritenga tukunga kua whakaritea e ngā ture tiaki taiao.
Whakamutunga Me arotahi te maimoatanga wai parahanga pepa ki te whakapai ake i te auau wai hangarua, te whakaiti i te kai me te tuku wai parahanga, ā, i te wa ano, me tūhuratia ngā tikanga maimoatanga wai parahanga pono, ōhanga me te whai hua ka taea te whakamahi katoa i ngā rauemi whai hua i roto i te wai parahanga. Hei tauira: ka taea e te tikanga whakapūmau te whakahoki mai i ngā totoka muka i roto i te wai mā, me te tere whakaora tae atu ki te 95%, ā, ka taea te whakamahi anō i te wai mārama; ka taea e te tikanga maimoatanga wai parahanga tahunga te whakahoki mai i te konutai hauwai, te konutai whanariki, te konutai whanariki me ētahi atu tote konutai i honoa ki ngā mea rauropi i roto i te wai pango. Ka whakatikatika te tikanga maimoatanga wai parahanga whakakore i te uara pH o te wai parahanga; ka taea e te whakatōtōtanga whakapūmau, te whakapūmau rānei te tango i ngā matūriki nui o te SS i roto i te wai parahanga; ka taea e te tikanga matū matū te tango i te tae; ka taea e te tikanga maimoatanga koiora te tango i te BOD me te COD, he pai ake mō te wai parahanga pepa kraft. Hei tāpiri, kei reira anō hoki ngā tikanga maimoatanga wai parahanga hanga pepa e whakamahia ana i te kāinga me tāwāhi.
