He aha e ti'a ia tatou ki te mohio te pH wai?

Ka rite ki tatou katoa mahara i te kura te matū akoranga, te pH - he wae o te hauwai katote mahi He rite ki te kōaro taupū kōaro o te hauwai katote mahi. Ko te kupu, te wai he pH rite ki te 7, me te e 10 ^-7 kiore ia rita o ngā katote hauwai, me te wai o te pH 6 - 10 ^-6 kiore ia rita. kia rerekē ngā uara tauine te pH i roto i te whānui mai i te 0 ki te 14.

I roto i te whānui, whakaaro wai ki te pH o iti iho i te 7 ki te kia waikawa, ki te pH nui ake i 7 - kawakore. Ko te whānuitanga noa o te pH mō ngā pūnaha wai mata takoto i roto i te whānui i 6.5 ki te 8.5, me hoki ngā pūnaha raro - i te 6 ki te 8.5.

Uara Water pH (H ₂ 0) he rite ki te 7 i te 25 ° C, engari i roto i te whakapā ki te hāorarua waro i roto i te huru, te hünuku tenei taurite ki te pH - e pā ana ki 5.2. tino tūtohutia hoki o whakapā tata ki hau kōhauhau, pH, me te pāmahana o te wai ki te kia rite hohoro whakamatauria rite taea. I muri i pH o te wai e kore ko te mehua o te pūmautanga o te tauhohenga waikawa kawakore ranei me e kore e hoatu i te pikitia tino o te āhuatanga te take mō te whāiti te supply wai ranei.

wai ngohengohe

I roto i te whānui, i te wai ki te pH iti (iti iho i te 6.5) he waikawa, ha'iriiri e, me te ngohengohe. Ko te kupu, kia tomo wai te katote whakarewa pērā i te rino, konupora, parahi, mata, me te konutea i te aquifer, paipa wai me te taiepa. Na reira, ko te wai ki te pH iti kia:

• Kei roto ngā taumata teitei o konganuku paitini;
• arahi ki kino taimi halá, ki putorino whakarewa;
• whai konganuku ranei reka kawa;
• rinena peitatanga;
• i te āhuatanga "puru-matomato" poke anga me manga.

Ko te ara matua ki te whakaoti i te raruraru o te wai pH iti ko te whakamahi o te neutralizer. whakaorangia ana te reira i te otinga ki te wai ki te aukati i tauhohe ki te wai supply motu wai ranei waikura -hiko. He pūtahuri angamaheni - matū pungarehu houra. Neutralization o enei tikanga faarahi te ihirangi konutai i roto i te wai.

wai pakeke

Water ki te pH i runga 8.5 he mārō. e kore e tohu te reira i te mōrearea hauora, engari ka taea e meinga raruraru rerehua. Enei raruraru ngā:

• Hanganga o te "tauine" toenga ranei i runga i putorino me huaki.
• reka kawakore i roto i te wai, e taea te hanga kawa reka kawhe.
• hanganga Tauine i runga i rihi, mīhini horoi, puna kaukau.
• Uaua i roto i te whiwhi i te pahuka o te hopi, me teretere, me te hanganga o te putunga rewakore i runga i kakahu, me te pera i runga i. D.
• Ko te hekenga i roto i te tōtika o te hatete hiko wai.

Ka rite ki te tikanga, enei raruraru puta ina pae te pakeke i 100 ki te 200 mg CaCO ₃ / rita, i te mea ōrite ki te 12 karamu ia kārani. kia tamărûhia Water i te whakamahi o te utu katote i te tua o te pungarehu, ranunga houra-kotakota ranei, engari ake i nga tukanga e rua te ihirangi konutai i roto i te wai.

wai inu PH

hiahiatia aro tupato ki te mana pH te i ngā wāhanga katoa o te maimoatanga wai ki te whakarite te kounga pai, me te disinfection wai. Ahakoa te tikanga e kore pānga tika i runga i kiritaki te pH o te wai, ko reira tetahi o te tino nui ngā tawhā kounga te wai whakahaere. Hoki te disinfection whai hua ki te tohu māota pH kia pai kia iti iho i te 8. PH pūnaha tohatoha kokoru wai me te mana kia ki te whakaiti te waikura o nga putorino. Kore ki te rave i te reira kia arahi ki te paru o te wai inu, me ona paanga kino i runga i te reka, kakara, me te ahua.

Ka rerekē te pH tino arotau mō ngā rauemi rerekē i runga i te hanganga o te wai, me te āhua o te rauemi hanga whakamahia i roto i te pūnaha tohatoha rānei, engari te nuinga o reira takoto i roto i te awhe 6.5-9.5. kia hua i mehema poka noa, breakdowns i ngā tipu maimoatanga uara pH Extreme.

Ko te taumata pai o te pH ionized wai mo te wā roa-kohi tangata he i waenganui i 8.5 me 9.5 (a kore ake atu i te 10.0) ki te uara ORP pai o e pā ana ki 200mV-300mV (me te i roto i tetahi take e kore runga ake i 400mV).

PH o te wai i roto i te poka

Ka rite ki ahau whakahuatia i runga ake, pH - nui āhuatanga e kore anake te wai inu engari ano mo te harotoroto, pera hoki te disinfection o te wai kei te tonu whakamahia chlorination te nuinga, te whakamahi i māota me te disinfection tōtika kaha tei runga i te uara tuatahi o te pH wai.

Māota Ko te kaihoko ringihia matua ki te ārai i te whanaketanga o mate i roto i harotoroto tūmatanui, engari tauhohe hoki māota ki matū organic i roto i te wai me ngā puka e-hua o te disinfection (PDP): mea organic - he pärönaki o matū humic i hanga e te pāhekoheko o te wai ki te werawera, mimi, makawe, pūtau kiri me toenga o ngā hua tiaki whaiaro e taka ki roto ki te wai i kaikauhoe. taea ana te ruri tirotiro PDI rite te moni o pūhui halogenated katoa. Ētahi PPD ake i te mōrea o te whakawhanake i huangō, e carcinogenic irritating ki kanohi, me te kiri ranei.

Ko te ingoa whānui māota o te waikawa chlorous, e ngā tauhohe te hau māota ki te wai. Rewa i roto i te wai, ngā momo waikawa o te pēhau me he uara pKa o 7.5.

Ko nui atu whai hua atu i pēhau, patu huakita, cysts, pua, me te huaketo tautauā waikawa Chlorous. Ko te kupu, ki te kei te uara pH o te puna kaukau i te taumata raro o te whānuitanga te whakarite, e hiahiatia ana moni iti o māota mo te tohu ano o te disinfection, a na reira kua hanga e i roto i te wai iti pea PDP mōrearea. Ka rite ki whakaaturia e maha rangahau, ko te taumata pH paetahi o te wai i roto i te poka wai i roto i te whānui i 7.5 ki te 8.0. Na roto i te whakaiti i te pH ki 1-0.5 wae tika (ki runga, ki te 7,0-6,5) tino nui haere ngā taumata o PDI, e ano hoki gennotoksichny.

Methods mō te faaotiraa o pH

He taupū kōaro te tauine pH, e te tikanga e ia hua heke ranei e 1 ira tohu te huringa i te take o 10. Hei tauira, he otinga ki te pH o 11 ki te 10 ngā wā atu kawakore atu i te otinga ki te pH o 10. He maha ngā tikanga me pehea ki te whakatau i te pH o te wai .

Whakatau i o pH te whakamahi i takai whakamātautau

takai Test Ko te pepa tohu waikawa, te huri te tae aro ki rerekē i roto i te pH. Ka taea te hokona ratou i roto i mōkai toa, rite ratou e maha whakamahia ki te whakatau i te pH o te wai i roto i te kākahi (ara he tātāu iti o tenei tohu kia hua i roto i te mate o te ika).

I roto i te whakapā ki te wai ka huri i te tae o te tïrau whakamātautau. E anake koe ki whakarite te tae hua ki te tauira tūtohi tae i runga i te mōkihi, me te whiwhi i te uara motuhake. Tenei tikanga mō te whakatau pH he tere, ohie, ngāwari, engari kua he hapa tika nui.

pepa tohu waikawa "Rottinger"

Hokona takai pH i roto i te toa taputapu hauora i roto i to koutou pa. I muri te tātari ngā whakamātautau ph (mai i Chinese cheap me mutu Tatimana utu), ka haere matou ki te mutunga e te hapa iti i roto i te whakaaturanga i homai e takai ph Tiamana "Rottinger". Ko te mōkihi, ko te tauine tohu o te 1 ki te 14 (te whānuitanga e wātea ana mōrahi!) A 80 takai ph, i te mea nui hoki te wa roa. Ki te taea te whanganga enei takai ph wai e kore anake, engari te pH hoki fluids koiora pēnei i huware, mimi, me te pera i runga i. Mai he utu tino (e pā ana ki 3000rub), a mo ki a ratou i ki te hoko rongoā papare mo whakatika, te pepa tohu waikawa "Rottinger", te utu o e kore e nui ake 250-350 moni mita ph pai., E mahi rite te taputapu faufaa i roto i te whakatau i te taumata ph pū.

Whakatau i o pH te whakamahi i pH-mita

I roto i te kirihou karaihe ranei kapu kohia tauira wai (20-30 ml). horoia te pūrere pūoko te ki te nui te iti o te wai māturu, a ka rumakina i roto i te otinga tahi me te pūoko pāmahana. Ko te āwhata o te pūrere whakaatu koe i te pH tangohia o te otinga whakamātautau. kia whanau te reira i roto i te ngakau e pā te tika o te inenga whakatika auau o te pūrere, hoki e whakamahi rongoā paerewa ki te pH rahinga mohiotia. he tika, ohie, nohopuku tenei tikanga o te whakatau pH, engari titau utu rauemi nui whakaritea ki te mua, me nga pūkenga māmā o te mahi ki te taputapu taiwhanga me rongoā matū.

Ko te kupu, ko te pH wai - ko te wā e kore e tika i te akoranga matū kura, engari ano hoki i te tohu o te kounga wai, e me te mana i roto i te tikanga ki te karo i te raruraru taputapu me te hauora.
