Flotators Industrial mō te purenga o te wai ururua: te momo o te pūrere, te parau tumu whakahaere

I teie mahana, he take taiao i te tepu upoko i tata hui katoa o kāwanatanga o te ao. Ko te kahore ngaro kua meinga e te taiao te karakia hou o te rautau 21. 2017 whakapuakina te tau o te tiaki taiao i roto i Russia, a reira mātauranga taiao - tetahi o nga mahi mo tenei tau.

He aha e hiahia ahau ki te pure wai?

O te katoa kararehe o te Ao Ocean, anake 3% - he wai hou, o nei 68% - ko reira te kōpaka (e kore e tika ana mō te inu), 30% - puna raro (maha i oneone poke) me 2 anake% - kua hurihia puna wai. Mai i te pikitia ao o te ao, ko reira mārama e te wātea o te wai hou - e kore te mea he akiaki tika, engari ko reira ētahi wā he papai.

wai Waste hangaia i roto i nga mahi ōhanga o hinonga, i roto i te nui o täoke i roto i ngä nohanga rawa i te whakaaetia me ngā ture. Tikanga, Ko reira he konganuku taimaha (rino, nika, parahi, mata, mēkuri, cadmium, etc)., Te hinu kohuke, totoka whakatārewatia, konumohe, surfactants waihanga (surfactants waihanga, ko katoa e huka mo te tangata ke). Enei matū tomo nga roto, whakapōrearea i te mahi noa o biogeocoenoses moana, rereke te oneone, whakapataritari te tupu o te ngä pükohu puru-matomato, he paitini ki kararehe. He paitini ki te tangata ano hoki enei täoke.

O te mahi ohaoha tangata i roto i ngā whare fare noho me nga whare tūmataiti hua hoki nui o pollutants. I roto i te whānui, i enei surfactants me ururua organic, engari taka ki roto ki te poka, me te whakarewa tai.

He aha te mea he skimmer pūmua mō maimoatanga puunaha?

Skimmer - he pūrere mō te tango o poke pai i te tikanga te wai physico-matū. Āhua e korero ana, te huarahi ko tetahi o te kōwae tukatuka matua i roto i nga hangarau toi me te maimoatanga puunaha. E te reira wahi i runga i te skimmer seperation matua o solutes me te maimoatanga wai ki runga ki tohu paerewa.

kia tikanga flotators Industrial kia hoki tipu nui, a mo te motokā, rere i roto i te rahi me te rauemi.

Ko te whāinga matua, ko te ki te tohatoha i te skimmer me maunu i te wai rewa roto nga pollutants e whakaahua ana ia ratou ki te puka rewa. I roto i te taputapu, tukua rangi te ki te whakarei ake pānga horoi.

Ko te parau tumu whakahaere o te skimmer mō maimoatanga puunaha

hāngai ana te parau tumu o te mahi kei te i runga i te skimmer ki kia horoia te haere i roto i te reo o mirumiru rangi mo te whakaaro o te pahuka i hanganga. huaina ana tēnei pahuka i te flotoshlam, kua nekehia nei ka whakaritea ki te pūrere dewatering motuhake. Ki mirumiru horo, ka kawea atu i te contamination, te tua mua o matū motuhake - coagulants me flocculants. Ēnei rauemi i adhesiveness nui, i.e. te āwhina ratou täoke ki agglomerate ki ia atu, me te ki te mirumiru rangi, hanga pera-ka karanga te flocculi.

Pounamu, haere i te pupuha te pupuha taputapu tokonaki maha ranei, tutaki ki te täoke tāpiapia. kawea te tukanga taua i roto i rite te roa rite kore e te wai tae te pānga horoi e hiahiatia ana.

matatini o te tukanga, ko te ki te whakarite tika i te horopeta o coagulant me flocculant kia ko tiketike nui hoki te adhesion o te mirumiru te kaha adhesion, engari kihai i nga tawerewere hua rawa nui taimaha, kia rite kore ki te tūkino i te mirumiru rangi.

He ara iahiko kei te skimmer mō maimoatanga puunaha

Technology, Ngae te skimmer rite te wae tukatuka matua ngā tonu te tipu matū me te taputapu mō te hanga mirumiru hau. Kaiwhakahohe Ko te pāmu tank ki tauhohenga (coagulants, flocculants, alkali ki te whakarite te pH) me te piere mo te ranu i te kaiwhakahohe ki te wai.

Ka rite ki te pūrere mō te whakaputa mirumiru hau rite te tikanga whakamahia saturator e tohu ana i te ruma rangi Mixing ki te wai ki te waihanga i tētahi ranunga wai-rangi. I tua atu, ko napravlyayuetsya i skimmer tenei ranunga. rite rawa pūrere carbonation te ki te papu kaha mō te rere rangi.

e kore te Skimmer whakamahia anake, kua whakaurua tonu te reira i roto i te kaupapa purenga wai katoa. te tikanga ngā o te tuatahi atamira parataiao, maimoatanga tinana-matū (Coagulator skimmer ranei) me te muri horoi aunoa i runga i te whiriwhiringa Whakaoti ara iahiko.

I roto i te mau parau te tahi atu, e kore e taea e te skimmer whakarato te purenga katoa, he tika he kōpuku kotahi, tono preprocessing me te pou i tenei. Tomo ki roto ki te onepu skimmer atu poke pokepoke, ranei arahi ki te kore pūrere. Ano, e kore e taea e tenei pūrere whakarato disinfection me horoi tino o ngā hua hinu. Na reira, i muri i te tāutanga tika UV me sorption (ranei te pūkaha) whiriwhiringa.

hāngai ana hoahoa schematic te i runga i te tukanga tēnei waka. Tēnei waka - mirumiru tenei maimoatanga puunaha o rangi i roto i te tikanga ki te tango matū wairewa, ka emulsified. tukua Water te ki te wae tukatuka matua. He hoki i roto i te pēhanga aratau (depressurized ranei) rite i mua kaiwhakahohe tukua i roto i te piere. Hoki e whangai nga mirumiru rangi flotator mā pūrere carbonation. I roto i te skimmer mō te purenga wai puta tauhohenga puunaha maimoatanga me mirumiru rangi, puta te nuinga koropupū i te puka o te flocculation flotoshlama. nekehia atu supernatant Flotoshlam te i te mata wai e te nekeneke kota i roto i te maramara tautopenga.

Ko te tino ātete ki te kolevaniyam pūkaha tenei Koinei, Heoi ki te mata kei te haere i te reira āta i roto i te tikanga e kore e ki te wahi i te pahuka i.

pūrere skimmer

Skimmer - he ipu tuwhera o parahi kirihou ranei, kua rite rawa ki te tikanga kota ki te kohikohi flotoshlama me te he i te raro koeke. Skimmer uhinga a te aroaro o te pupuha wai-rangi mō te hoko i te ranunga o te saturator, a ki te tautuhi anō i te whawhati tata flotoshlama te putu i hoki te tuku wai ururua me te rere o te wai te pure. Tāuta i te skimmer, te tikanga kei runga i te pae o te mahi mo te haratau.

momo flotators

rerekē Flotators puunaha maimoatanga rite ki te āhua o kukū, te wai kei te ki te mirumiru, me te āhua o mirumiru. ngā te tikanga tino noa mīhini, pressurized me electroflotation. tēnei waka pressurized fakahu'unga ruma carbonation me rōpū köurarangi. Haunga, i roto i tenei tikanga e whakamahia ana pinepine tauhohenga. e kore e Electroflotation Me te tipu matū me te saturator, kia rite ki te hāngai ki runga ki te whakakorenga o te electrodes i roto i te wai.

tēnei waka aunoa

Mechanical (impeller ranei) whakaranu presupposes e i tere tiketike tukinga ki te mirumiru wai. Tenei momo o te maimoatanga wai mo te wai e pängia ana ki te huka me te hau kukū. I roto i te tikanga aunoa, e kore e taea te whakamahi i te matū hohe, mai te arepurepuraa i hanga e te stirrer, wehe noa nga täoke tawerewere. I te kau, e kore te mea noa tēnei waka aunoa, mai uaua whakarato pānga horoi rawaka.

Tikanga, tenei wāhanga ngā flotators purenga mo te purenga o te wai ururua i te hinu.

tēnei waka pēhanga

I roto i tenei take flotators puunaha maimoatanga pūrere rawa kaiwhakahohe carbonation me te ōhanga. Saturator Ko te ruma i roto nei i te werohanga rangi i raro i te pēhanga ki runga ake kōhauhau. rite Tauwaenga i te saturator, ka karanga te ranunga hau-wai. Ko te momo tino noa o te tēnei waka me te ake pinepine whakamahia tenei. puta te tukanga purenga i te pretreatment kaiwhakahohe (coagulant flocculant ranei) me te pēhanga muri ranunga wai maimoatanga. Kei te piri ia mirumiru hau ki te poke ano, mai i te mea he kaha attraction nui e tika ana ki te rohe wā (hau-wai). faaineineraa tuatahi o te wai whakapiki i te kaiwhakahohe horoi, no te mea hanga reira floccules (micelles), ano nei i te tetahi kaha o attraction. nekehia atu te nuinga o te wai kei te roto i te putorino wai e purea ki atu horoi ake ranei tautuhi anō. I te tihi o te pūrere kota motuhake tango i flotoshlam - te pokenga, puhia ki mirumiru hau whakarunga i roto i te puka takiwa.

Ko te painga matua o te pēhanga tēnei waka ko te whānui o ngā tono ngā. Ko te āhuatanga o te aroaro o ngā pūrere atu ngā (te whakahaere kaiwhakahohe, papua carbonator), e tangohia ake wāhi, me te hiahia ki te kia aunoa (hei tauira, te kōwhiringa o matū hohe horopeta). Faaotiraa kaiwhakahohe rahinga whai wāhi nui rite te horopeta iti e arahi ki iti purenga (kore matūriki iti katoa rewa hiatonga), me te horopeta nui kia arahi ki te meka e kore nga mirumiru e te tu i te taimaha o nga tawerewere, ka haafaufaa, hua ano i whakaiti o te pānga horoi.

Elektroflotator

Tenei momo flotators maimoatanga puunaha e faikehekehe fuonounou me noho pai o te whakamahi. Kei roto i te tikanga i roto i te wai-iahiko ki te kia purea me nga haurehu wehenga i te electrodes. I roto i te tukanga-iahiko puta skimmer: oti hauwai i te pitoiho, te pitoake - hāora. A, no te whakamahi i electrodes wairewa (hei tauira konumohe rino ranei) anō kukū te wai te ki katote maitai ki kāwanatanga hāora tiketike e whai te tūranga o te matū hohe ki te waihanga tawerewere poke. āwhina ana tēnei tukanga ki te tutakina me ki te whakato atu ara pollutants i te wai. Mai kore te mea nui te wāhi skimmer, i roto i taua huru i reira he he tawerewere piripiri pai, me te rangi pozyrkov e whakarato ana i te pānga horoi rawa.

Ko te painga matua o te pūrere taua ko te kore o te tipu matū me ētahi atu pūrere mōmona ki te nui rawa o te purenga wai. Ko te huakore Ko te kohi pūngao tiketike, me te hiahia mō te taputapu mo te tango o te hauwai.

tēnei waka pupuha

I roto i tenei take, te whakamahi i nozzles motuhake ki te whakauru i te rangi i roto i te wai tukatuka tukua e te ki te mīhini tēnei waka, i reira te roherohea ki te ranunga biphasic. Ko te painga o tenei tikanga, ko te iti kākahu o nga wahi tāutanga, me te reira te ora ratonga roa.

tipu matū

I roto i te tahi mau tikanga, te tauhohenga tēnei waka e whai ake nei whakamahia ki te whakapai ake i te pānga purenga:

• māngai mō te huri i te pH - he waikawa me alkali e tapiritia ki te wai ki te whakarite noa tikanga mahi coagulant me flocculant;
• coagulants - tauhohenga e whakatairanga flocculation me he rino, me te konumohe tai;
• flocculants - tauhohenga e hua tawerewere nui me te ake pūmau (floccules) ka tohu he pūhui polyacrylamide.

Ko te ngoikoretanga matua o te aroaro o te kaiwhakahohe tikanga maimoatanga wai ko te akiaki ia o te aroaro o ngā kaimahi, me te wāhi e me tohatoha he oko me reactors. He mea nui hoki ki te whiriwhiri i te horopeta tika o tauhohenga, i te mea ka taea empirically anake.
