Pūhaumāota Polydiallyldimethylammonium(PolyDADMAC) he mea whakamahi whānuitia hei whakapūkara i te polymer cationic, ā, he mea nui tana mahi i roto i te ao o te maimoatanga wai. Ko te PDADMAC te mea e whakamahia whānuitia ana hei whakapūkara, ā, i ētahi wā ka whakaranua ki ngā algaecides. Ka whakamāramahia e tēnei tuhinga ngā painga me te uara tono mahi a te PolyDADMAC mai i ngā āhuatanga o tana tikanga mahi, ngā horopaki tono me ngā rautaki motuhake hei whakapai ake i te whai huatanga o te maimoatanga wai.
Ngā āhuatanga taketake o PolyDADMAC
He pūhui ngota ngota teitei te PolyDADMAC, he nui ngā rōpū kationika i roto i tōna hanganga ngota ngota, ā, ka taea e ia te mimiti i ngā matūriki me ngā korori i roto i te wai. Ko ōna āhuatanga matua ko:
1. Te kaha o te kationitangaKa taea e ia te whakakore wawe i ngā matūriki e iri ana i roto i te wai me te utu kino.
2. He pai te wairewatanga ki te waiHe ngāwari te waimeha ki te wai, ā, he watea hoki mō te tono ki te wāhi mahi.
3. Te pumau matūKa taea e ia te pupuri i te mahi whakapūkara tino pai i roto i ngā awhe pH rerekē, te taiao whakahāora me te taiao kutikuti miihini teitei. He kaha te ātete o te PDADMAC ki te haurehu.
4. He iti te paitiniE tutuki ana i ngā paerewa tiaki taiao, ā, he pai mō te maimoatanga wai inu.
Te tikanga mahi a PolyDADMAC i roto i te maimoatanga wai
Ka whakararuraru i ngā matūriki iri me ngā matū wai wai kua utua kinotia i roto i te wai, ā, ka whakapūpū i a rātou mā te whakakore hiko me te hononga mimiti. He pānga nui tōna ki te tango i ngā tae me te tango i ngā mea rauropi.
PolyDADMACka whakapai ake i te whai huatanga o te maimoatanga wai mā roto i ngā tikanga e whai ake nei:
1. Te whakakore i te utu
Ko ngā matūriki me ngā korori e iri ana i roto i te wai he maha ngā utu kino, ka puta ai te ātete i waenga i ngā matūriki, ā, ka uaua ai te taunga. Ka taea e ngā rōpū kationika o te PolyDADMAC te whakakore wawe i ngā utu kino, te whakaiti i te ātete hiko i waenga i ngā matūriki, me te whakatairanga i te whakapūmau matūriki.
2. Pānga hono
Mā te hanganga ngota ngota mekameka roa o te PolyDADMAC matotoru-teitei ka taea e ia te hanga i tētahi "piriti" i waenga i ngā matūriki maha, ka whakakotahi i ngā matūriki iti hei putunga nui ake, ā, ka pai ake te whai huatanga o te whakapūtātanga.
3. Te whakapakari i te pānga hopu kupenga
Ka taea e te PolyDADMAC te whakapakari i te "hanganga kupenga" i hangaia e te matū whakakōkī kore-waro i roto i te maimoatanga wai hei hopu i ngā mea angiangi kua tautau, inā koa i roto i te wai paru nui, i te wai poke rawa rānei.
Ngā horopaki tono o PolyDADMAC
1. Te maimoatanga wai inu
Ka whakamahia te PolyDADMAC hei whakapūkara wai hei tango i te paru, ngā matūriki iri me ngā mea rauropi mai i te wai inu. I taua wā anō, nā te iti o te paitini me ōna āhuatanga tiaki taiao, ka taea e ia te tutuki i ngā paerewa haumaru wai inu.
2. Te tukatuka wai para
I roto i te maimoatanga wai para o ngā tāone me ngā ahumahi, ka whakamahia te PolyDADMAC hei whakapai ake i te mahi whakamaroke paru, hei whakaiti i te nui o te makuku o te keke paru, me te whakaiti nui i ngā utu whakahaere.
3. Te purenga wai ahumahi
I roto i ngā ahumahi hiko, matū hinu me ētahi atu ahumahi, ka whakamahia te PolyDADMAC mō te purenga o te wai ahumahi pēnei i te wai whakamatao me te wai kohua hei whakaiti i ngā mōrearea o te tauine me te waikura.
4. Te hanga pepa me te umanga kakahu
E whakamahia ana te PolyDADMAC hei āwhina pupuri me te tātari hei whakapai ake i te tere pupuri o ngā muka me ngā whakakī i roto i te tukanga hanga pepa, me te whakaiti anō hoki i te nui o ngā mea kua tautau i roto i te wai para.
Ngā rautaki hei whakapai ake i te whai huatanga o te maimoatanga wai me te PolyDADMAC
1. Te arotau i te whakahaere inenga
He hononga tata te horopeta o te PolyDADMAC ki te kukū, te tohatoha rahi o te matūriki me ngā āhuatanga poke o ngā matūriki iri i roto i te wai. Mā te arotau i te horopeta mā te whakamātautau ipu ka taea te whakanui ake i tōna pānga rere me te karo i te horopeta nui rawa e arahi ana ki te pikinga o ngā utu, ki te parahanga tuarua rānei o te wai.
2. Pānga honohono me ngā mea whakapūkara kore-ora
Mā te whakamahi i te PolyDADMAC me ngā mea whakapūkara kore-waro (pērā i te polyaluminium chloride me te konumohe sulfate) ka tino whakarei ake i te pānga whakapūkara. I muri i te whakakorenga a te PolyDADMAC i te kawenga mata o ngā matūriki, ka hangaia e ngā mea whakapūkara kore-waro he ngārara nui ake mā te mimiti me te whakatō.
3. Whakapai ake i te taumata aunoa o ngā tukanga maimoatanga wai
Mā te āwhina o ngā pūnaha whakahaere aunoa, ka taea te aroturuki me te whakarerekē i te horopeta o te PolyDADMAC i te wā tūturu hei whakatau i ngā huringa o te whai huatanga o te maimoatanga i puta mai i ngā piki me ngā heke o te kounga wai.
4. Whakapai ake i ngā āhuatanga whakaoho
I muri i te tāpiri i te PolyDADMAC, mā te kaha me te wā e tika ana te whakaoho ka taea te whakapai ake i tōna marara me te whai huatanga o te whakapūpū. Tērā pea ka pakaru ngā pūpū i te whakaoho nui rawa, engari mā te kore whakaoho ka whakaiti i te pānga whakaranu.
5. Whakatikatikahia te uara pH
Ka tino pai te mahi a te PolyDADMAC i raro i ngā āhuatanga kūpapa ki ngā āhuatanga kawakore ngoikore. Mēnā ka rongoatia te wai tino waikawa, tino kawakore rānei, mā te whakarerekē i te pH o te wai ka pai ake te pānga o te rere o te wai.
Ngā Painga o PolyDADMAC
1. Teitei o te whai huatangaTe hanganga tere o ngā putunga hei whakapai ake i te whai huatanga o te wehenga totoka-wai.
2. Whānuitanga o ngā tonoE pā ana ki ngā momo āhuatanga wai, inā koa te wai he nui te paru me te nui o te ihirangi rauropi.
3. Te tiaki taiaoHe iti te paitini me te pirau-ora, e rite ana ki ngā whakaritenga tiaki taiao.
Hei mea tino whai huamea whakapūkara, he nui ngā painga o te PolyDADMAC ki te whakamahinga i roto i te mara o te maimoatanga wai nā te kaha o te cationicity, te wairewa pai ki te wai, me te whānui o te whakamahinga. Mā te arotautanga tukanga me ngā rautaki whakahaere whaitake, ka taea te whakapai ake i te whai huatanga o te maimoatanga i roto i te purenga o te wai inu, te wai para me te wai ahumahi.
