Inkinga ikuphi-ingabe oxygen emanzini? Ukusabela umoya-mpilo ne-amanzi. Oxygen ukugcwaliswa

Mhlawumbe manje, ngisho izingane ukwazi ukuthi ifomula amakhemikhali ukuze amanzi - H ₂ O. Nokho, lo mbono, kodwa eqinisweni ziyoncibilika emanzini lenqwaba izinto kokubili umsuka organic wezinto ezingaphili. Amanzi ahlanzekile, njengoba sazi, ayinakho ukunambitheka noma ukuhogela, kodwa noma ngubani angakwazi uqinisekise ukuthi ezimweni eziningi akusiyo. Ngo amanzi okuphuza, isibonelo, aqukethe ubuningi nosawoti amaminerali, okuyinto ulunika ukunambitheka okunosawoti. Ngo ntshashintshe uqukethe zonke izinto okwenziwa ngazo kuziwa mbeni. I ngqo yokwakheka amanzi kuye lapho kocingo, ngoba ezindaweni ezahlukene ke nabo izinto ezahlukene. Somewhere bamakhemikhali bangathola ku ketshezi onesigqi esinamandla, endaweni ethile - ahlukahlukene izinto eziphilayo.

Kwenzeka kanjani?

Amanzi uketshezi jikelele. amanzi distilled ubhekwa njengamagugu ambiwa phansi amsulwa ku chemical umqondo izinto, kodwa ngemva kwesikhashana nje leyo ndawo ilahlekelwa esimweni saso sokuqala. Nasi isizathu: amanzi kuphela okuhle ukuze ekugcineni uthole kuwo amangqamuzana izinto ezihlukahlukene kusukela emoyeni. Emvelweni, kwenzeka futhi ngenxa imisebenzi ebalulekile eziphilayo imvelo aqueous.

Amagesi emanzini

Ukuthululela amanzi ku ingilazi, kungenzeka ukubona Bubbles igesi, okuzokwenza esisogwini izindonga isitsha. Bekanye nosawoti kanye nezinye izinto emanzini ancibilikisa uqobo bese kuthi amagesi. Okokuqala kuyinto nitrogen emoyeni, kanye nomoya-mpilo, isikhutha, futhi kwezinye izimo ngisho i-methane ne-hydrogen sulfide. Ngaphezu kwalokho, amanzi abandayo ancibilikisa amagesi ungcono efudumele, ukuze ephansi izinga lokushisa, ayanda lokuhlushwa igesi. Futhi okuphambene nalokho - nokunyuka lokushisa solubility incipha.

Imithombo yamagesi ziyoncibilika

Kodwa lapho ingabe zonke lezi zinhlanzi izinto zithathwa emanzini? Nitrogen ngokuvamile ziyoncibilika nokuxhumana emkhathini, i-methane - ngokuthintana ngamatshe noqhekeko udaka phansi, kanye sulfide hydrogen kwakhiwa njengoba abolile izinsalela organic. Ngokuvamile, i-hydrogen sulfide eziqukethwe izingqimba ajulileyo, angabe esavuka kwamanzi. Ngezinye lokuhlushwa yaso ephezulu zokuphila akunakwenzeka, isibonelo, oLwandle Olumnyama ngesikhathi engaphezu kuka 150-200 amamitha ukujula kusukela amanzi okusezingeni eliphezulu ukugcwaliswa serovodorom cishe akukho eziphilayo, ngaphandle ezinye amagciwane.

Mpilo futhi njalo equkethwe emanzini. Kuyinto ejenti enemisebenzi oxidizing kancane ubola hydrogen sulfide ngakho ukunciphisa okuhlushwa yayo. Kodwa lapho enza oxygen emanzini? Mayelana naye sizoxoxa ekhethekile.

umoya-mpilo

Cishe zonke izinto eziphilayo kudingeka umoya-mpilo. Abantu ukuphefumula vohduhom, okuyinto inhlanganisela amagesi ingxenye enkulu okuyinto ngokunembile ke.

Izakhamuzi imvelo yasemanzini futhi kudingeka lento, ukuze lokuhlushwa oxygen emanzini - lena kuyinkomba ebaluleke kakhulu. Ngokuvamile kukuwe 14 mg / l esimweni amanzi zemvelo, futhi ngezinye izikhathi ngisho nangokwengeziwe. Esikhathini uketshezi olufanayo ogeleza usuka empompini, umoya-mpilo lincane kakhulu, futhi kulula ukuchaza. Thepha amanzi ngemva engayitholi sidlula izinyathelo uhlanzekile eziningana futhi oxygen ziyoncibilika - kwakwakhe eziguquguqukayo. Ngenxa yalokho, lo exchange igesi nge emoyeni phakathi nengxenye enkulu yezakhi nje iphele. Ngakho lapho enza oxygen emanzini, uma kungekhona aphume Umoya-mpilo omncane?

Empeleni, lokhu akulona iqiniso ngokuphelele, kusukela emoyeni, futhi, kuthathwa, kodwa inani ziyoncibilika ngenxa contact emkhathini, lincane kakhulu. Ukuze nokuxhumana umoya-mpilo ne-amanzi bekulokhu ngokwanele ngempumelelo, izimo ezithile ayadingeka: izinga lokushisa ongaphakeme, umfutho ophakeme futhi usawoti iphansana. Babebona Lutho neze njalo, futhi ukuphila kwakungeke yayikhona injalo manje uma indlela kuphela kumiswa igesi kwabezindaba aqueous kwaba nokuxhumana emkhathini. Ngenhlanhla, kukhona imithombo ezimbili umsuka oxygen emanzini. Okokuqala, i-molecule igesi ziyoncibilika semali eziqukethwe iqhwa nemvula amanzi, kanti okwesibili - futhi lokhu liwumthombo oyinhloko - ngenxa ye-photosynthesis, ukusebenza izimila zasemanzini phytoplankton.

By the way, naphezu kweqiniso lokuthi i-molecule yamanzi moya une-oksijini, isuse izinto eziphilayo lapho ophilayo Yiqiniso, ngeke sikwazi. Ngakho-ke, kuze kube yaneliswani ke buhlanjululwe share.

Ukubaluleka ulwelwe

Bambalwa abantu ekuphileni kwansuku zonke kubonisa ukuthi esiwuphefumulayo futhi kungani umoya Ukwakheka ncamashi linje. Cishe wonke umuntu uyazi ukuthi iningi izinto eziphilayo, emoyeni aphefumula, it is ingashintshwa ukuze le nhlanganisela. Kodwa uma kuziwa phansi emoyeni imvelo, asivelanga umbuzo. Futhi lapho i-oksijini emanzini? Thanda phansi, zikhona izitshalo eziningi ngumuntu inqubo okuthiwa i-photosynthesis, usithathela ukukhanya ne-carbon dioxide, sikude O _2.

Nokho, uma uma sikubeka ngokuqondile, emashumini eminyaka amuva nje, ngoba noma ngabe yisiphi isizathu, isintu siye phansi ingxenye enkulu kwamahlathi. Kodwa umbuzo we inhlekelele yembulunga yonke kodwa, nakuba inani labantu emhlabeni njalo anda, ne-oksijini ukusetshenziswa
omkhulu. Futhi kubaluleke kakhulu kule ndaba yilena lona lisiza ezihlala olwandle, iningi ke ngezindleko zabo bazogcwalisa ngamanzi nomoya-mpilo. Ezinye izinhlobo zabantu nezilwane zasolwandle adle, kodwa isibalo sabo sincane esanele ngempumelelo fotosintezirovaniya. Lokho umsuka oxygen emanzini, okusho ukuthi ngenxa exchange igesi emkhathini, futhi emoyeni. It photosynthesis ulwelwe - umthombo wayo oyinhloko. Phela, ngenxa izinqubo ezenzeka ezitshalweni, liye zanqwabelana-mpilo eyinhloko emkhathini, kodwa manje kukhona kuphela nokugcina ke Ukwakheka njalo.

Iqhaza le-oxygen ziyoncibilika (DO)

Naphezu kweqiniso lokuthi imigudu yokuphefumula impilo yasemanzini is ngokufanako kuka abakhileyo imvelo phansi emoyeni, badinga zonke izinto ezifanayo. Okokuqala sikhuluma mpilo, ufeza indima ebalulekile ekuphileni kwama-iningi eziphilayo. Futhi uma thina kokuyikhipha emkhathini, lapho isabelo yayo ucishe esigculisayo azungeze 21%, izakhamuzi emifuleni, ezilwandle nakuzo izilwandle bathembele kakhulu umoya-mpilo kangakanani emanzini eziqukethwe yazo. Ngaphezu inhlanzi, ukuncipha komoya-mpilo kuyadingeka nokutshala izitshalo. Nokho, imikhiqizo yayo ngokuvamile ephakeme kunaleyo ezingeni ukusetshenziswa, ngakho lokhu akufanele kusenze ukukhathazeka.

amazinga evamile

Ngenxa yendima yayo ebalulekile e ukusebenza evamile zemvelo, RK ezingeni ngokuvamile kungaphansi ukulawula by izazi zesayensi yezinto eziphilayo futhi ezemvelo. Phela, zonke izinto ngokwemvelo ixhunyiwe, ukuhlukumeza esele igesi e emanzini kungabangela izinkinga ezweni elingumakhelwane, uma axhunyiwe. Ngokuvamile, izilinganiso eyenziwa ngaphambi emini, ngalesi sikhathi lokuhlushwa igesi kwamanzi iba esiphezulu of afinyelela ku 14 mg / l. Le nkomba echayeke iyehla iyenyuka wahlushwa futhi zonyaka, kodwa akufanele iwe ngezansi 4mg / L.
Ukunciphisa lokuhlushwa 2 mg / l noma ngaphansi kubangela mass ngokwempilo yangenyama abakhileyo hydrosphere. Empeleni - kusuka umoya. Ukwehla kancane kancane kungase kubonise nokungcoliswa kwamanzi futhi kungase ekugcineni ibangele ukufa zezakhamuzi yasemanzini.

RK simiso semvelo yokufakelwa

Ukubaluleka aeration ezinhle, isibonelo, aquarium. Ngakho-ke kubalulekile ukuba ningabi nje kuphela ufake amaphampu ekhethekile ukumpompa emoyeni emanzini yokumatisa ke umoya-mpilo, kodwa futhi, isibonelo, umhlaba phansi ulwelwe ahlukahlukene njengoba kudingeka. Yiqiniso, labo abathanda okufana, sobuhle bayo kuqala nokusemqoka ezithakazelisayo semvelo, kodwa akufanele sikhohlwe mayelana kwato kanye nokuqina ezithile.

Uma sikhuluma zokudoba, ukukhiqizwa amapharele kanye nezinye izimboni ezithile zalolu hlobo, ngaphezu izinyathelo letehlukahlukene lokuhloswe ngato ekwenteni ekulondolozweni kwezindawo liningi ngokwanele i-oksijini yahlakazeka emanzini, kufanele kube njalo ukukala lokhu ipharamitha ngokusebenzisa ukuhlolwa okukhethekile. Lapho kocingo kubalulekile ukuthi kwakungekho ukuxhumana emoyeni, kungaba baphendukezele imiphumela yokuhlaziya.
