Coagulants - he aha te mea tenei? Hea a he aha coagulants whakamahia

Ko te whakamahi o te wai pokekore whakapiki i te hauora me te tangata mate, haunga ora te tinana iho, mā te whakamahi i ona ake whenua rāhui. Iwi mō ngā rau tau noho tata awa me ngā roto, te whakamahi i aua puna i hoatu ora ki te taiao. i mohio kua nuinga u'i i tahito ra pehea ki te pure wai mo nga hiahia o tangata mā te haere i te reira i roto i te papa o te paru me te onepu. I aua ra, kihai i iwi whakamahi coagulants (tenei taonga, whakaputaina nei e te maimoatanga tuatahi o te wai ora-hoatu tenei ra).

Taua wai ma rerekē

I roto i te ao hou te whakaaro reira e, i pā atu, iwi kia whakamahi i roto i to ratou mau utuafare e toru ngā momo o te wai:

• pato wai kua haere e te paerewa horoi pokepoke maha, me te tātari i roto i ngā tāngata whai motuhake;
• whare, tamărûhia mua ki te ārai i te hanganga tauine i roto i taputapu whakawera whakamahia mō te horoi me te horoi;
• inu, Kei te whakamahia anake hoki ingestion me te tunu kai.

fare wai mania whakarato pūnaha supply wai tāone. Hoki whaiaro kāinga-pou-maimoatanga te whakamahi i ngā whiriwhiringa, ko te hanganga o te pūnaha, ka mohio te whaitake o te tahi mau kohuke (pērā i shungite). I tua atu, i reira he coagulants, ringihia te wai mo te whakamahi kāinga.

Eaha te tupu ki te wai i mua i tomo i te putorino

I mua i te whakatau me te filtration hua he maimoatanga taratara tuatahi o te wai te tikanga mo te supply ki ngā pūnaha supply wai tāone. Tuatahi, i roto i te ipu motuhake hohoro te ranu wai me te coagulant (he matū motuhake). A, no te coagulant heke te repulsion hiko o te matūriki rewa i roto i te wai ko, piri tahi ratou. whakahaere tenei a hohoro ake te horoi i roto i te whakatau, me te filtration.

Ko te tukanga i roto i te kotahi tank kia muri e pā ana ki te kotahi meneti. Ki te he wā wa iti e kore e whakarato i te taurite hiahiatia o te ranu te taonga ki te wai. I roa taunekeneke kia whatiia floccules i hanga (te hohenga ka slipshiesja matūriki ke). I muri haere i roto i te maha o ngā tāke i reira coagulants mō te wai i konatunatua ki taua mea ki te auau āta whakaiti, i raro te wai te ki parataiao.

He aha te mea he kupu ataahua "flocculation"

Coagulants - he tauhohenga matū. Ehara i te katoa e kino ana ki te matū tangata e taea te ahu i roto i te filtration mua i roto i te wa poto. kei roto i te āhua rewa etahi o ratou. Ki te he hakari i te wai hydrosols ranei poke, nga coagulants hoki maimoatanga wai i te wa o te pāhekoheko ki a ratou te hanga i te hohenga rewakore i roto i te puka o te slurry. Ko te tukanga o te hanganga o matūriki pai agglomerated, te "puranga" nui me huaina flocculation. Te rahi o te matūriki hou e taea e ki runga ki te maha mitamano.

O te akoranga, ka taea e koe pure wai i ngā poke filtration mua, engari e rave rahi tau e tangohia ai, a roto i te meka titauhia whakainu i nga ra i roto i rahinga nui. Ki ko nohopuku nui te tukanga horoi i roto i te mihini e tapiritia coagulants. te whakaiti i tenei te tuku tikanga o te wai i katoa o ngā matū kino ki te 30-45 meneti. Ki te noho tere o nga pa, me nga pa e taea ki te whakamahi i tura'i te wai i te whakamarie o to ratou mau fare.

Eaha te tupu i te tipu parakaingaki

I roto i te wai, ara mārama i te para, te tikanga kei te nui nui o poke. I roto ia ratou Ko te rauemi e whai ake nei:

• gypsum me te kotakota;
• onepu me te paru kamaka;
• yl me te köurarangi;
• waihā konganuku paku wairewa;
• huakita;
• matū rewa;
• ngā whakatārewatanga.

matūriki taimaha, me te nui ki te papatipu motuhake tiketike tika tere taka ki te raro o te noho, mo te 1-2 meneti. Kōkiri i te tukanga parataiao (hohenga hanganga) o matūriki pai, e taea muri ake ki te rua tau e, te wai i honoa coagulants. Tenei pūhaumāota ferric, alumina ngāwhā, rino pūkawa, gidroksosulfaty hydroxychloride me te konumohe, he ranunga o te rino, me te konumohe tai, opacifiers paru, rerekē whakatārewatanga flocculating me brighteners.

Hoki purenga me te māramatanga o te wai i roto i te pūnaha o te whakatau poutū i runga i te 1 rita o 50 ki te 100 ml kaiwhakahohe. Rahi me Katahi tahi i te mahi o ngā matū matūriki colloidal hohenga, e atu ngāwari wehea e whakatau me te filtration.
