Njira yochizira madzi onyansa okhala ndi cyanide ndi madzi onyansa a sodium cyanide

Pankhani yoteteza chilengedwe, chithandizo cha madzi otayira okhala ndi cyanide ndi madzi otayira a Sodium cyanide chakhala nkhani yofunika kwambiri kwa nthawi yayitali. Chifukwa cha kupita patsogolo mwachangu kwa mafakitale, makamaka m'mafakitale monga electroplating, metallurgy, ndi mankhwala, kutulutsa madzi otayira okhala ndi cyanide kwakhala kukuwonjezeka chaka ndi chaka, zomwe zikuika pachiwopsezo chachikulu ku chilengedwe. Chifukwa chake, kufufuza njira zamakono zochizira madzi otayira okhala ndi cyanide moyenera, kotsika mtengo, komanso kosamalira chilengedwe ndikofunikira kwambiri.

Makhalidwe ndi Zowopsa za Cyanide - Muli Madzi Otayidwa

Cyanide - wokhala ndi madzi oipa nthawi zambiri amakhala ndi zinthu zambiri za cyanide, zomwe zimapezeka m'madzi mwaulere kapena zovuta. Pakati pawo, zitsulo - cyanide complexes, monga mkuwa - cyanide complexes ndi zinc - cyanide complexes, zimakhala zokhazikika komanso zovuta kuchotsa pogwiritsa ntchito njira zochiritsira. Kuonjezera apo, madzi owonongeka angakhalenso ndi ayoni ena olemera kwambiri, organic matter, acids, alkalis, ndi zinthu zina, zomwe zimakhala zovuta kwambiri, zomwe zimawonjezera kuvutika kwa mankhwala. Kutulutsa kwa cyanide - komwe kumakhala ndi madzi oyipa sikungowononga matupi amadzi komanso kumachulukana kudzera muzakudya, zomwe zimabweretsa chiwopsezo chanthawi yayitali ku chilengedwe komanso thanzi la anthu.

Technologies Chithandizo cha Cyanide - Muli Madzi Onyansa

Poganizira mikhalidwe ya cyanide - yomwe ili ndi madzi onyansa, njira zamakono zochizira zomwe zimagwiritsidwa ntchito kwambiri masiku ano zimaphatikizapo njira zochizira makutidwe ndi okosijeni, njira zochizira ma electrolytic, njira zosinthira ion - zosinthira, njira zamankhwala zamankhwala, komanso kugwiritsa ntchito umisiri wambirimbiri.

Njira Zochizira Oxidation

Njira ya Alkaline Chlorination

Pansi pa mikhalidwe ya alkaline (nthawi zambiri yokhala ndi pH pakati pa 10 ndi 11), ma oxidants monga chlorine kapena sodium hypochlorite amawonjezedwa kuti apangitse zinthu za cyanide kukhala nayitrogeni wosakhala ndi poizoni ndi Carbon dioxide. Njirayi ndi yosavuta kugwiritsa ntchito, imakhala ndi zotsatira zokhazikika pa chithandizo, ndipo mankhwala amapezeka mosavuta komanso otsika mtengo. Komabe, ingayambitse kuipitsa kwina ndipo imakhala ndi mphamvu zina zowononga pa zipangizo.

Hydrogen Peroxide Oxidation Njira

Pansi pa zinthu za acidic kapena zamchere, hydrogen peroxide imagwiritsidwa ntchito ngati oxidant kutulutsa zinthu za cyanide kukhala nayitrogeni ndi madzi. Ndikoyenera kwambiri kuthira madzi otayidwa ndi zinthu zambiri za cyanide, koma mtengo wamankhwala ndi wokwera, ndipo momwe zimachitikira ziyenera kuyendetsedwa mosamalitsa.

Njira ya Ozone Oxidation

Pogwiritsa ntchito oxidizing amphamvu a ozoni, zinthu za cyanide zimasinthidwa kukhala zinthu zopanda poizoni. Kugwiritsa ntchito bwino kwamankhwala ndikokwera kwambiri ndipo kulibe kuipitsidwa kwachiwiri, koma ndalama zogulira zida ndi ndalama zogwirira ntchito ndizokwera.

Fenton Oxidation Njira

Fenton reagent yopangidwa ndi hydrogen peroxide ndi mchere wachitsulo amagwiritsidwa ntchito popanga okosijeni wamankhwala kuti awononge bwino zinthu za cyanide.

Electrolytic Chithandizo Njira

Ma electrochemical oxidation reaction amagwiritsidwa ntchito kuwononga zinthu za cyanide m'madzi onyansa. Pazifukwa zina, ayoni a cyanide m'madzi onyansa amapangidwa ndi okosijeni kukhala carbon dioxide, nitrogen, ndi ammonia. Ndioyenera kuthira madzi otayidwa ndi ayoni apamwamba a cyanide, koma amawononga mphamvu zamagetsi ndipo amatha kutulutsa mpweya wapoizoni wa cyanogen chloride.

Ion - Kusinthana Njira

Strong - base anion - resins wosinthanitsa amagwiritsidwa ntchito kusinthanitsa ndi ayoni a cyanide mu yankho, kukwaniritsa kuchotsedwa kwa ayoni a cyanide. Ndi oyenera kuchiza cyanide - munali madzi oipa ndi ndende sing'anga ndi otsika, ali mkulu mankhwala dzuwa, ndipo akhoza kuchira wapatali ayoni zitsulo, koma mtengo mankhwala ndi mkulu.

Njira Yochizira Zamoyo

Kupyolera mu kuwonongeka kwa tizilombo tating'onoting'ono, zinthu za cyanide zimasinthidwa kukhala zinthu zopanda poizoni kapena zochepa - poizoni. Ndizokonda zachilengedwe komanso zokhazikika, koma zimafuna malo oyenera a chilengedwe (monga kutentha, pH mtengo, etc.) ndi nthawi yayitali yochizira. Njira zochiritsira zodziwika bwino zachilengedwe zimaphatikizira njira ya sludge yoyendetsedwa ndi biofilm.

Njira Zophatikiza

Poganizira zovuta za cyanide - zomwe zimakhala ndi madzi onyansa, kugwiritsa ntchito njira zamakono zambiri nthawi zambiri kumatengedwa. Mwachitsanzo, "njira ya alkaline chlorination + ion - kuwombola njira", "electrolytic treatment njira + ion - exchange njira", "hydrogen peroxide oxidation method + biological treatment method", etc. Kupyolera mu njira zophatikizira, mu -kuya mankhwala a madzi onyansa angapezeke, ndipo khalidwe lotayirira likhoza kukhala bwino.
