Ekuphishekeleni impilo yezinga eliphezulu namuhla, amanzi amaminerali njengommeleli weziphuzo zezempilo, ukuphepha kwawo kuye kwaba omunye wabathengi abakhathazeke kakhulu. Umagazini wakamuva we-Hong Kong Consumer Council "Choice" ukhiphe umbiko lapho bahlole khona izinhlobo ezingu-30 zamanzi asemabhodleleni emakethe, ikakhulukazi ukuze bahlole ukuphepha kwala manzi asemabhodleleni. Ukuhlolwa kwezinsalela zokubulala amagciwane kanye nemikhiqizo ekhiqizwayo kutholwe ukuthi izinhlobo ezimbili ezidumile zamanzi asebhodleleni e-China, "Spring Spring" kanye "neMountain Spring," zinama-micrograms angu-3 we-bromate ikhilogremu ngayinye. Lokhu kugxilisana kweqe inani eliphezulu le-bromate emanzini emvelo amaminerali namanzi entwasahlobo yokwelashwa kwe-ozone eshiwo yi-European Union, okuvuse ukukhathazeka nezingxoxo ezisabalele.
* Isithombe esivela kunethiwekhi yomphakathi.
Ukuhlaziywa komthombo we-bromate
I-Bromate, njengenhlanganisela ye-inorganic, ayiyona ingxenye yemvelo yamanzi amaminerali. Ukubukeka kwayo kuvame ukuhlobene eduze nendawo engokwemvelo yendawo yekhanda lamanzi kanye nobuchwepheshe bokucubungula obulandelayo. Okokuqala, i-bromine ion (Br) endaweni yekhanda lamanzi iyisandulela se-bromate, etholakala kakhulu emanzini olwandle, emanzini anosawoti angaphansi komhlaba kanye namanye amadwala anothe ngamaminerali e-bromine. Lapho le mithombo isetshenziswa njengendawo yokukhipha amanzi emanzini amaminerali, ama-bromine ion angangena enqubweni yokukhiqiza.
II.inkemba esika nhlangothi zombili ye-ozone disinfection
Enqubweni yokukhiqiza amanzi amaminerali amaminerali, ukuze kubulawe ama-microorganisms futhi kuqinisekiswe ukuphepha kwekhwalithi yamanzi, abakhiqizi abaningi bazosebenzisa i-ozone (O3) njenge-detoxifier. I-ozone, ne-oxidation yayo eqinile, ingabola ngempumelelo izinto eziphilayo, ingasebenzi amagciwane namagciwane, futhi yaziwa njengendlela yokwelapha amanzi ephumelelayo nengenabungane. I-Bromine ions (Br) emithonjeni yamanzi izokwakha i-bromate ngaphansi kwezimo ezithile, njengokusabela ngama-oxidizing agents aqinile (afana ne-ozone). Yilesi sixhumanisi, uma singalawulwa kahle, singaholela kokuqukethwe kwe-bromate ngokweqile.
Phakathi nenqubo yokubulala amagciwane e-ozone, uma umthombo wamanzi unamazinga aphezulu ama-ion e-bromide, i-ozone izosabela ngala ma-ion e-bromide enze i-bromate. Lokhu kusabela kwamakhemikhali kwenzeka futhi ngaphansi kwezimo zemvelo, kodwa endaweni elawulwa ngokuzenzisa yokubulala amagciwane, ngenxa yokuhlushwa okuphezulu kwe-ozone, izinga lokusabela liyashesha kakhulu, okungabangela okuqukethwe kwe-bromate kudlule izinga lokuphepha.
III. Umnikelo Wezinto Zemvelo
Ngaphezu kwenqubo yokukhiqiza, izici zemvelo azikwazi ukushaywa indiva. Ngokudlondlobala kokushintsha kwesimo sezulu emhlabeni wonke kanye nokungcoliswa kwemvelo, amanzi angaphansi komhlaba kwezinye izindawo angase athonyeke kakhulu amathonya angaphandle. Njengokungena kwamanzi olwandle, ukungena komanyolo wezolimo kanye nezibulala-zinambuzane, njll., okungase kwandise okuqukethwe kwe-bromide ion emithonjeni yamanzi, ngaleyo ndlela kwandise ingozi yokwakheka kwe-bromate ekwelapheni okulandelayo.
I-Bromate empeleni iyinto encane ekhiqizwa ngemva kokukhishwa kwe-ozone kwemithombo yemvelo eminingi njengamanzi amaminerali kanye namanzi entwasahlobo asezintabeni. Ikhonjwe njenge-Class 2B engaba yi-carcinogen emhlabeni jikelele. Lapho abantu bedla kakhulu i-bromate, izimpawu zesicanucanu, ubuhlungu besisu, ukuhlanza kanye nesifo sohudo kungenzeka. Ezimweni ezimbi kakhulu, lokhu kungase kube nemiphumela emibi ezinso nasesimiso sezinzwa!
IV. Iqhaza lamalambu e-amalgam anengcindezi ephansi ye-ozone ekuhlanzeni amanzi.
Amalambu e-amalgam anengcindezi ephansi ye-ozone, njengohlobo lomthombo wokukhanya we-ultraviolet (UV), akhipha izici ze-spectral zamagagasi amakhulu angu-253.7nm namandla okuvala inzalo asebenzayo. Aye asetshenziswa kabanzi emkhakheni wokwelapha amanzi. Indlela yayo eyinhloko yokusebenza ukusebenzisa imisebe ye-ultraviolet ukubhubhisa ama-microorganisms. Ukwakheka kwe-DNA ukuze kuzuzwe inhloso yokuvala inzalo nokubulala amagciwane.
1, umphumela wokuvala inzalo ubalulekile:Ubude begagasi be-ultraviolet obukhishwa isibani se-amalgam esinengcindezi ephansi ye-ozone sigxiliswe kakhulu cishe ku-253.7nm, okuyibhande elimunca kakhulu i-DNA ye-microbial efana namagciwane namagciwane. Ngakho-ke, isibani singabulala ngokuphumelelayo amabhaktheriya, amagciwane, ama-parasites namanye ama-microorganisms ayingozi emanzini, ukuqinisekisa ukuphepha kwekhwalithi yamanzi.
2 .Ayikho insalela yamakhemikhali:Uma kuqhathaniswa ne-ejenti yokubulala amagciwane, isibani se-amalgam esinengcindezi ephansi sibulala amagciwane ngendlela ephathekayo ngaphandle kwanoma iyiphi insalela yamakhemikhali, sigwema ingozi yokungcoliswa kwesibili. Lokhu kubaluleke kakhulu ekwelapheni amanzi okuphuza aqondile njengamanzi amaminerali
3, ukugcina izinga lamanzi lizinzile:Enqubweni yokukhiqiza amanzi amaminerali, isibani se-amalgam esinengcindezi ephansi ngeke sisetshenziselwe ukubulala amagciwane omkhiqizo wokugcina kuphela, kodwa futhi singasetshenziselwa ukwelashwa ngaphambi kwamanzi, ukuhlanza amapayipi, njll., ukusiza ukugcina izinga lamanzi lizinzile. lonke uhlelo lokukhiqiza.
Kodwa-ke, kufanele kuqashelwe ukuthi isibani se-amalgam esinengcindezi ephansi ye-ozone sikhipha igagasi elikhulu le-spectrum ku-253.7nm, futhi ubude begagasi obungaphansi kuka-200nm bucishe bube buncane futhi alikhiqizi ukugxila okuphezulu kwe-ozone. Ngakho-ke, ayikho i-bromate eyeqile ekhiqizwa ngesikhathi senqubo yokuvala inzalo yamanzi.
I-Low Pressure Ozone Yamahhala ye-Amalgam Lamp
V. Isiphetho
Inkinga yokuqukethwe kwe-bromate ngokweqile emanzini amaminerali kuyinselele eyinkimbinkimbi yokwelashwa kwamanzi edinga ucwaningo olujulile nokuhlola okuvela emibonweni eminingi. Izibani ze-ozone mahhala ze-mercury ezicindezelayo eziphansi, njengamathuluzi abalulekile emkhakheni wokwelashwa kwamanzi, ngalinye linezinzuzo eziyingqayizivele nokusebenza. Enqubweni yokukhiqiza amanzi amaminerali, imithombo yokukhanya efanele kanye nezindlela zobuchwepheshe kufanele zikhethwe ngokuvumelana nesimo sangempela, futhi ukuqapha nokulawula izinga lamanzi kufanele kuqiniswe ukuze kuqinisekiswe ukuthi ithonsi ngalinye lamanzi amaminerali lingahlangabezana nezindinganiso zokuphepha nokuhlanzeka. Ngesikhathi esifanayo, kufanele siqhubeke nokunaka intuthuko yakamuva kanye nezinhlelo ezintsha zobuchwepheshe bokuhlanza amanzi, futhi sinikele ngokuhlakanipha okwengeziwe namandla ekwenzeni ngcono ukuphepha kanye nekhwalithi yamanzi okuphuza.
