Water purenga i konganuku taimaha: tikanga me ngā taputapu

Water purenga i konganuku taimaha, kahore he feaa, he he take nui ki te whiwhi rite-ki-te whakamahi, ma, me te mahaki ki te inu te tangata. Na roto i te konganuku taimaha he āhuatanga matū e whai āhuatanga konganuku me te kupu riro i te taimaha ngota nui.

Kua i ratou i te tino kaha te paheketanga i runga i kaiao tangata me te kararehe mahi, a ka whai hoki i te taonga o te piki i roto i whēkau me te kopa, me te meinga kino tūnguru ki te hauora. Ko reira he mea nui ki te whakatū i ngā tipu maimoatanga whiriwhiringa wai i rino, parahi, mata, nika, konutea, konukurahina, mēkuri, cadmium me te hiriwa.

Ko te hiahia mo te taua te tātari tika ki te meka e no te mea o te whakamahi whānui o te wai mō te ngā ahumahi kukū o enei konganuku he tiketike rawa i roto i te kararehe. Pollutants i ngā hanganga rerekē me ngā āhuatanga, e te tikanga e hoki ia o ratou momo he tika ki te huihui ki ngā tikanga me ngā pūrere.

Water purenga i konganuku taimaha i roto i te puka o ngā katote whakaputaina e te tikanga matū me te heke ki te huringa i roto i te pH o te reo ki te taumata e hiahiatia ana. Ki runga ki pa te uara PH o 9.0-10.5 riro rewakore tetahi konganuku me te hohenga e nekehia atu e tino noa.

Tīpakonga o ngā matū, whakaputaina nei e te maimoatanga ahumahi wai tei runga i te āhuatanga e whai ake nei:

- te viivii ore e hiahiatia ana;

- kukū o te parakino;

- aroaro ngaro o poke ranei.

Kia whakamaoritia taonga insolubilizing, taahiraa wehe ratou, maha te whakamahi i mahara whakatau o te whakarewa. whakamana mahi te ki precipitating whakamahi ipu motuhake i nei e whakatahia te matūriki whakatakotoria mo te dewatering me te whakamaroke. Plus, tenei tikanga ko tona tapatahi, me te kino - he tūtohutanga tiketike ki te aroaro o te pūhui no rapae e taea pokanoa ki te tukanga waipara. kia tenei hopi, hauwai waikuratei teretere ranei.

Tikanga, i roto i te wai, kiriuhi purea kukū maitai e kore nui 1 mg ia rita, me i te tahi atu taha o te tātari e hāngai ratou i roto i te puranga gelatinous.

Kei te whakaaro te reira i tenei purenga wai i konganuku taimaha te ki hei te whai hua tino me whaihua. Ko tōna kounga tiketike e tika ana ki te āhuatanga motuhake o kiriuhi, pērā i:

1. Ko te selectivity tiketike, i roto i te kupu atu, te kaha mo te wehenga o matū o mau huru rerekē. Ko te rehea me whitinga roto semipermeable iho te wai anake, tino wetekina i poke. kohikohi Tata i te tahi atu taha o te membrane.

2. Ko te koranu i te mea tino te pakitara wehewehe whakarewa kaha me te ātete ki te whakaeke matū.

3. Ko rite whai hua te membrane me tino whakatinana i te tikanga o te mahi puta noa i te wā o te whakamahi. Ko te painga o te tikanga, ko te e kua takoto te poke whakarewa i runga i te mata tātari me te Toke ona kōputaputa, me i roto i ngā huarahi maha e nekehia i mea membrane.

Tirohia o taua purenga, ko te rerewai whakamuri. āhuatanga i tēnei tikanga i roto i taua i te otinga o (te wai poke) tono pēhanga e nui tona ake. Ko te āhuatanga o te tukanga ngā nga whakaritenga kounga tiketike o te rauemi o e horoi tāutanga, me te whīwhiwhi o te tango i apa kukū.

nui nui o te wai ki te kukū iti o konganuku taimaha he tika ki te pure i te utu katote. Ka rite ki mohiotia te, e hāngai ana ona hangarau kei runga i te whakamahi o resins utu katote mō katote whakarewa e kohikohi mata. Tautuhinga mō ēnei mahi tukua ki te mau tonu i te kāpia mo te maha o nga tau, ki te kahore hoki ratou Shade.

Heoi, ko te tikanga horoi tino tino ko te mahia hangarau tino matatini o te maimoatanga huringa ki ultrafiltration. Heoi, kei te whakamahia tenei tikanga anake hoki iahiko me te hiko ahumahi, te wai ururua nei kei te ōrau nui o rongoā ururua me te helanitami kukū. Hoki taua mahi mā te whakamahi i reactors motuhake.
