He mea tino kitea te uaua o ngā wāhanga wai para o te tāone. Ka puta he paru miraka i te hinu e haria ana e te wai para o ngā wharekai, ka puta he kikorangi-kakariki te pahuka e puta mai ana i ngā hopi horoi, ā, he parauri pouri te nuinga o te wā i roto i te wai para. Nā tēnei pūnaha whakauru maha-tae, ka nui ake ngā whakaritenga mō te ngā mea whakakore tae wai para: me whai mahi maha pērā i te tango i ngā matū, te tango i te huka me te whakaiti i te waikura i te wā kotahi. E whakaatu ana te pūrongo whakamātautau o tētahi tipu maimoatanga para i Nanjing ka taea e te whānuitanga o te rerekētanga o te tae o tōna waikura te eke ki te 50-300 nekehanga, ā, he uaua tonu te whakaū i te tae o te waikura e tukatukahia ana e ngā waikura tango tae tuku iho i raro i te 30 nekehanga.
Ngā mea whakakore tae waipara hou kua tutuki i a rātou tētahi peke mahi nui mā te hoahoa hanganga ngota. Mā te whakamahi i te polymer dicyandiamide-formaldehyde kua whakarerekētia hei tauira, ka hangaia he pānga tahi e ngā rōpū amine me te hydroxyl i runga i tōna mekameka ngota: ka hopukina e te rōpū amine ngā tae anionic mā te mahi hiko-pūmau, ā, ka honoa te rōpū hydroxyl ki ngā katote konganuku hei whakakore i te tae konganuku. E whakaatu ana ngā raraunga tono tūturu kua piki ake te tere tango chromaticity o te wai para o te tāone ki te neke atu i te 92%, ā, kua piki ake te tere whakatōtō konumohe mā te 25%. He mea nui ake ko tēnei whakakore tae wai para ka taea tonu te pupuri i te mahi teitei i raro i ngā āhuatanga pāmahana iti.
Mai i te tirohanga a te pūnaha maimoatanga wai katoa, he maha ngā whakapainga ka kawea mai e te taputapu whakakore tae waipara hou. Mō te whai huatanga o te maimoatanga, whai muri i te whakamahinga o te taputapu whakakore tae waipara hiato i roto i tētahi tipu wai kua whakahokia mai, i whakapotoa te wā pupuri o te tāke whakaranu tere mai i te 3 meneti ki te 90 hēkona; mō te utu whakahaere, i whakaitihia te utu o ngā matū mō ia tana wai mā te 18% pea, ā, i whakaitihia te putanga paru mā te 15%; mō te atawhai taiao, i raro iho i te 0.1 mg/L te nui o te monomer toenga, he iti iho i te paerewa ahumahi. Ina koa i te wā e tukatuka ana i te paru whatunga waipara whakakotahi, he pai tōna kaha tiaki mō ngā ru chromatic ohorere i puta mai i te ua nui.
E toru ngā ara auaha e arotahi ana ngā rangahau o nāianei: ka taea e ngā kaiwhakakore tae waipara photocatalytic te memeha i muri i te maimoatanga hei karo i te parahanga tuarua; ka taea e ngā kaiwhakakore tae waipara aro-pāmahana te whakarite aunoa i te āhua o te ngota i runga i te pāmahana o te wai; me ngā mea whakarei-koiorangā mea whakakore tae wai para whakauru i ngā āheinga pirau huakita. Kei te akiaki tonu ēnei auahatanga i te maimoatanga wai para o ngā tāone ki tētahi huarahi whai hua ake, ā, matomato ake hoki.
