I te wā e tukatukahia ana te māpere me ētahi atu rauemi kōhatu, he nui te paura kōhatu me te wai whakamatao kei roto i te wai para e puta mai ana. Mēnā ka tukuna tika atu ēnei wai para, ehara i te mea ka maumauria noa ngā rauemi wai, engari ka poke kino hoki te taiao. Hei whakaoti i tēnei raruraru, ka whakamahia e tētahi umanga tukatuka kōhatu te tikanga matū mō te whakatō, me te whakakotahitanga o te polyaluminium chloride (PAC) me te polyacrylamide (PAM), me te whakakotahitanga o tetaputapu pēhi tātari, kia whai hua ai te maimoatanga me te hangarua o te paru para, me te waihanga anō hoki i ngā hua ōhanga tāpiri.
1, Ngā āhuatanga me ngā uauatanga o te maimoatanga o te waipara
Ko ngā āhuatanga o te wai para o te tukatuka māpere he nui te kukū o ngā totoka iri me te hanganga matatini. He uaua ki te whakatau i ngā matūriki angiangi o te paura kōhatu mā te taiao, ā, kei roto i te wai whakamatao ngā matū maha pērā i ngā matū horoi, ngā aukati waikura, me ētahi atu, e whakapiki ana i te uaua o te maimoatanga wai para. Ki te kore e tukatukahia pai, ka ārai ngā totoka iri i roto i te wai para i ngā paipa, ā, ka poke te oneone me ngā wai i roto i te wai whakamatao.
2、 Rere tukatuka pēhi tātari
Kua tāutahia e te umanga ngā mīhini tātari tino whai hua ki roto i te pūnaha maimoatanga paru. Tuatahi, tāpirihia te polyaluminium chloride me te polyacrylamide ki roto i ngā peere inenga kua whakaratohia me te mīhini tātari, ka whakarewahia, ka whakaohokia kia rite ki te ōwehenga. Ka whakahaeretia tika te rongoā rewa e te papu inenga hei tuku ki te tāke whakaranu o te mīhini tātari. I roto i te tāke whakaranu, ka whakaranua pai ngā matū ki te paru, ā, ka tere te puta o ngā tauhohenga totoka me te flocculation. Muri iho, ka uru te wai whakaranu ki te rūma tātari o te mīhini tātari, ā, i raro i te pēhanga, ka tukuna te wai mā te kakahu tātari, i te wā e mau ana te paru ki roto i te rūma tātari. Whai muri i te wā tātari pēhanga, ka hangaia he keke paru he iti te makuku, ka tutuki ai te wehenga pai o te totoka me te wai.
Hei whakarāpopototanga, ko te whakamahinga o te tikanga matū whakatītaha, me te polyaluminum chloride me te polyacrylamide, me ngā taputapu pēhi tātari hei rongoā i te wai para māpere he otinga whai hua, he ohanga, he hoa taiao hoki, he uara whakatairanga pai hoki.
