I. Papamuri o te kaupapa
He umanga tukatuka kai rahi-waenga e arotahi ana ki te tukatuka kai parai me te mīti, ā, he nui te wai para hinu nui e puta ana i roto i te tukanga whakaputa, kei roto hoki ngā poke pēnei i ngā toenga kai, ngā hinu kararehe me ngā hinu tipu me ngā pūmua. He tino rerekē te kounga o te wai para, he nui te hinu, ā, he ngāwari te tuku tika ki te aukati i ngā paipa me te whakatō wai. E ai ki te tātaitanga tauine whakaputa o te umanga, ko te tukunga wai para he 2.5m³/h. Hei whakatutuki i ngā whakaritenga o te tiaki taiao me te whakatutuki i te whanaketanga pumau, me hanga e ngā umanga he huinga pūnaha maimoatanga wai para whai hua me te pumau me te tapuwae kia iti ai te tapuwae kia eke ai te wai para ki te paerewa me te whakaiti i te tukunga paru.
II. Ngā tino take mamae o ngā kiritaki
He uaua te whakatau i te nui o te hinu: ko te nui o te hinu i roto i te wai para he ≥80mg/L, ā, he iti te pānga o te tukanga maimoatanga tikanga ki te wehenga o te hinu kua whakaemulhia, ka ngāwari ai te aukati i ngā wae maimoatanga o muri mai, te iti o te whai huatanga, me te nui o ngā utu tiaki.
Kāore i te rawaka te kaha tukatuka o ngā taputapu taketake: kāore e taea e ngā taputapu māmā o nāianei te whakatutuki i te hiahia tukunga o te 2.5m³/h, ā, he nui te rerekētanga o te kounga o te wai para, ka hua ake te mōrearea o te hipa i te paerewa tiaki taiao.
E rua ngā herenga o te wāhi me te tuku para: he iti noa te rohe e kapi ana i te tipu, e hiahia ana ki tētahi pūnaha maimoatanga kiato, kia whai hua hoki, ā, e whakatau ana i te raruraru o te tuku para kia kore ai e parahanga tuarua.
3. Ngā otinga ritenga
E ai ki ngā āhuatanga o te wai para hinu nui me ngā hiahia tuturu o ngā kiritaki, ka hangaia te tukanga maimoatanga whakauru o te "maimoatanga mua + te taunga toto + te tātari pēhanga diaphragm me te whakamaroke", ā, ka arotauhia te inenga rongoā me te whakamaroke paru kia tutuki ai te tango hinu whai hua me te mahi pumau.
1. Te rere o te tukanga
I te wāhanga o mua i te maimoatanga, ka haere tuatahi te wai para mā te whatunga miihini hei tango i ngā matūriki nunui o te toenga kai, kātahi ka uru ki te mahanga hinu whakatairanga, ā, ka whakamahia te mātāpono wehenga ā-papa hei tango i te paru hinu (tere tango ≥60%), ka whakaiti nui i te kawenga maimoatanga i muri mai.
Wāhanga whakapūpū me te whakapūpū: Whai muri i te maimoatanga o mua, ka tomo te wai para ki te tāke tauhohenga whakapūpū, ā, ka tāpirihia te PAC (polyaluminum chloride) me te PAM (polyacrylamide) mā te papu ine tika. Ka whakangaromia e te PAC te āhua whakapūpū o te hinu, ka whakatairangahia e te PAM te whakapūpū o ngā whakapūpū, ka hangaia he whakapūpū kei roto he hinu e ngāwari ana te whakapūpū, ā, ka tutuki te wehenga whai hua o te hinu, te wai me ngā wāhanga totoka e toru.
Te wāhanga wehenga totoka-wai me te whakamaroke: i muri i te whakapūmau, ka rere te wai para ki roto i te tāke whakapūmau hei wehe i te paru me te wai, ā, ka tukuna te wai para ki te paerewa. Ka pupuhihia te paru hinuhinu i raro ki roto i te mīhini tātari diaphragm, ā, ka whakaitihia te makuku o te paru ki raro iho i te 60% mā te whakaputanga diaphragm pēhanga teitei me te whakamaroke, ka hanga he keke paru totoka hei kawe me te whakakorenga ki waho. Ka whakahokia te tātari o te tātari pēhanga ki te wāhanga maimoatanga o mua hei whakatutuki i te maimoatanga kati o te wai para i roto i te tukanga katoa.
2. Ngā taputapu matua me ngā tawhā whakahaere
Kei te uho o te pūnaha tukatuka he taputapu tauhohenga matū kua whakauruhia me te kaha tukatuka o te 2.5m³/h, me te mīhini tātari diaphragm 30㎡.
Te horopeta PAC: 50-80mg /L, te horopeta PAM: 3-5mg /L, kia rite ki te whakarerekētanga wā-tūturu o te kounga wai whai mana, kia pai ai te pānga maimoatanga;
Kei te pūnaha he pūnaha whakahaere atamai hei whakatutuki i te mahi aunoa o te horopeta rongoā, te whakamaroke paru me ētahi atu hononga, me te whakaiti i te kaha o te mahi ā-ringa.
IV. Te pānga o te whakatinanatanga o te kaupapa
He pumau te kounga o te parapara, ā, e tutuki ana i te paerewa: i muri i te whakamahinga o te pūnaha, ka whakaitihia te nui o te hinu o te parapara ki raro iho i te 5mg/L, ā, ko ētahi atu tohu e hangai ana ki ngā paerewa tukunga ā-rohe;
He mea whakamiharo te pānga whakaiti paru: ka whakaitihia e te mīhini tātari diaphragm te nui o te makuku o te paru ki raro iho i te 60%, ā, ka whakaitihia te rahinga paru mā te 70% pea, ka tino whakaitihia te utu whakakorenga;
He ngāwari te whakahaere me te tiaki: he iti te wāhi e hipokina ana e te hoahoa whakauru, he nui te aunoatanga, he iti te mahi tiaki o ia rā, he pumau, he pono hoki te mahi mō te wā roa.
V. Whakarāpopototanga o te take
Mā te tukanga tukatuka mua kua whakauruhia, te whakatōtō totoka me te whakamaroke i te diaphragm pehanga teitei, ka whakatauhia e tēnei take ngā uauatanga o te maimoatanga wai para hinu nui i roto i ngā umanga tukatuka kai. He tino whai hua, he pumau, he kiato hoki te pūnaha, e kore e whakarite noa kia eke te wai para ki te paerewa, engari ka tutuki hoki te whakaiti me te tuku rauemi o te paru, ka whakarato ki ngā kiritaki he otinga tiaki taiao ōhanga me te whai hua.
