Ngā kukū whirihoranga mō ngā tono polyacrylamide anionic

Ko te polyacrylamide anionic te nuinga e whakamahia ana mō te whakapakari i te rere o te wai para, he āhuatanga rite ki te electrolyte polymer i roto i te reo kūpapa me te kawakore, he tairongo ki ngā electrolyte tote, ā, ka taea te hono i ngā katote konganuku utu nui ki roto i te gel kore-rewa, e whakamahia ana mō te wai whakaputa kāinga, te maimoatanga wai para ahumahi me te tāone, ā, ka taea hoki te whakamahi mō te whakamaroke paru kore-waro.

E toru ngā wāhanga matua o te polyacrylamide anionic:

I roto i te umanga whakarewa me te hanga whakarewa, ka whakamahia mō te purenga o te wai horoi hau i roto i te oumu tuwhera, te whakamārama i te wai para i roto i ngā tipu whakarewa paura me ngā tipu pikika, te purenga o ngā electrolytes me te whakamārama i te wai para hiko.

I roto i te mahi keri, e whakamahia ana mō te whakamārama i te wai horoi waro me ngā paru whakapūngā, te tātari waro ma, te whakamaroke i ngā paru (para), te whakamārama i ngā paru whakapūngā, te whakamātotoru me te tātari kukū, te whakamārama i te wai tukatuka rewa wera me te whakapūngā pāhare pākawa waro, te whakamārama i ngā paru whakapūngā fluorite me te barite, te wai tote mata mō te tukatuka tote, te whakamārama i te whakamaroke paru me te maimoatanga wai whakaora maina phosphate.

I roto i te maimoatanga wai para o ngā tāone me ngā ahumahi, ka whakamahia hei whakapai ake i te tango i ngā totoka iri, te BOD me te phosphate i roto i te wai para. Mā te tāpiri i te 0.25mg/L polyacrylamide hydrolyzed ki te tāke whakapūmau wai para tuatahi, ka taea te whakanui ake i ngā tere tango o te mea iri me te BOD ki te 66% me te 23%. Mā te tāpiri i te 0.3mg/L polyacrylamide anionic ki te tāke whakapūmau maimoatanga wai para tuarua, ka taea te whakanui ake i te tere tango o te mea iri me te BOD ki te 87% me te 91%, ā, ka taea te whakanui ake i te pānga tango phosphorus mai i te 35% ki te 91%. I roto i te maimoatanga o te wai inu me te wai para o te whare, ka whakamahia hei whakamārama i te mata, hei whakamārama i te wai para horoi me te whakatikatika i te tātari.

Ka whakaurua te wairewatanga o te whakaritenga polyacrylamide anionic:

1, e whakamahia ana i roto i te whakataunga parakaingaki, ko te kukū ōwehenga kua tūtohutia he 0.1%

2, tuatahi, tauhiuhia te paura ki te wai puna kia ōrite, ka whakaoho i te tere reo o te 40-60 RPM kia memeha rawa te pūmua i roto i te wai i mua i te tāpiri.

3, I te wā o te whakamātautau, tangohia te 100ml o te wai para, tāpirihia he 10% o te otinga polyacrylamide, ka whakaoho mārire, whakamahia he pūwero hei tāpiri mārire i te otinga PAM, 0.5ml i ia wā, kia rite ki te rahi o te pua konumohe i hangaia me te tata o te flocculant, te mārama o te supernitant, te tere o te whakapūmau, te inenga hei whakatau i te kaihoko tika.
