Kaʻina hana lapaʻau o ka wai ʻino cyanide a me ka wai ʻōpala sodium cyanide

Ma ke aupuni o ka hoomalu kaiapuni, ka lapaau ana o cyanide - loaʻa ka wai ʻino a me ʻO Sodium cyanide Ua lilo ka wai ʻōpala i kumuhana koʻikoʻi. Me ka hoʻomohala wikiwiki ʻana o ka hana ʻoihana, ʻoi aku hoʻi i nā ʻoihana e like me ka electroplating, metallurgy, a me nā kemika, ua hoʻonui ʻia ka hoʻokuʻu ʻana o ka cyanide - i loko o ka wai ʻōpala i kēlā me kēia makahiki, e hoʻoweliweli ana i ke kaiapuni. No laila, ʻo ka ʻimi ʻana i nā ʻenehana lapaʻau maikaʻi, hoʻokele waiwai, a me ke kaiapuni no ka cyanide - i loko o ka wai ʻōpala he mea nui loa.

Nā ʻano a me nā pōʻino o ka Cyanide - Loaʻa i ka wai ʻōpala

ʻO ka cyanide - i loko o ka wai ʻōpala ka mea maʻamau i loaʻa nā mea cyanide kiʻekiʻe - i loko o ka wai ma nā ʻano manuahi a paʻakikī paha. Ma waena o lākou, ʻoi aku ka paʻa a paʻakikī hoʻi e hoʻoneʻe ʻia ma o nā ʻano hana lapaʻau maʻamau. Eia kekahi, hiki i ka wai ʻino ke loaʻa i nā ion metala kaumaha ʻē aʻe, nā mea kūlohelohe, nā waikawa, nā alkalis, a me nā mea ʻē aʻe, me kahi hui paʻakikī, e hoʻonui ai i ka paʻakikī o ka mālama ʻana. ʻO ka hoʻokuʻu ʻia ʻana o ka cyanide - ʻaʻole i hoʻohaumia i nā kino wai wale nō akā e hōʻuluʻulu ʻia ma o ke kaulahao meaʻai, e hoʻoweliweli ana i ka wā lōʻihi i ke kaiaola a me ke olakino kanaka.

Nā ʻenehana lapaʻau no ka Cyanide - Loaʻa i ka wai ʻino

I ka nānā ʻana i nā hiʻohiʻona o ka cyanide - loaʻa ka wai ʻino, ʻo nā ʻenehana lapaʻau i hoʻohana nui ʻia i kēia manawa e pili ana i nā ʻano lapaʻau oxidation, nā ʻano hana electrolytic, nā ʻano hoʻololi ion, nā ʻano lāʻau lapaʻau, a me ka hoʻohana ʻana o nā ʻenehana lehulehu.

Nā ʻano Lapaʻau Oxidation

ʻO ke ʻano hoʻoheheʻe alkaline

Ma lalo o nā kūlana alkaline (ʻo ka maʻamau me ka waiwai pH ma waena o 10 a me 11), hoʻohui ʻia nā oxidants e like me ka chlorine a i ʻole sodium hypochlorite e hoʻoneʻe i nā mea cyanide i loko o ka nitrogen ʻawaʻawa ʻole a me Kelepona ʻokikene. He maʻalahi kēia ʻano hana e hoʻohana, loaʻa nā hopena lapaʻau paʻa, a loaʻa koke nā lāʻau lapaʻau a ʻaʻole pipiʻi. Eia nō naʻe, hiki iā ia ke hoʻoulu i ka haumia lua a loaʻa kahi hopena ʻino i nā lako.

ʻO ke ʻano o ka hydrogen peroxide

Ma lalo o nā kūlana acidic a alkaline paha, hoʻohana ʻia ka hydrogen peroxide ma ke ʻano he oxidant e hoʻoneʻe i nā mea cyanide i loko o ka nitrogen a me ka wai. He kūpono loa ia no ka mālama ʻana i ka wai ʻino me nā mea cyanide kiʻekiʻe, akā kiʻekiʻe ke kumukūʻai o ka mālama ʻana, a pono e hoʻomalu pono ʻia nā ʻano hopena.

Ozone Oxidation Method

Ke hoʻohana nei i ka waiwai oxidizing ikaika o ka ozone, ua hoʻoneʻe ʻia nā mea cyanide i nā mea ʻawaʻawa ʻole. He kiʻekiʻe ka maikaʻi o ka mālama ʻana a ʻaʻohe pollution lua, akā kiʻekiʻe ke kumukūʻai o nā lako hana a me nā koina hana.

ʻO ke ʻano o ka Fenton Oxidation

ʻO ka Fenton reagent i haku ʻia me ka hydrogen peroxide a me nā paʻakai hao e hoʻohana ʻia no ka oxidation kemika e hoʻohaʻahaʻa pono i nā mea cyanide.

Keʻano Lapaʻau Electrolytic

Hoʻohana ʻia ka hopena electrochemical oxidation e luku i nā mea cyanide i loko o ka wai ʻino. Ma lalo o kekahi mau kūlana, ua hoʻoneʻe ʻia nā ʻona cyanide i loko o ka wai ʻino i carbon dioxide, nitrogen, a me ka amonia. He kūpono ia no ka mālama ʻana i ka wai ʻino me nā ion cyanide kiʻekiʻe, akā hoʻopau ia i ka ikehu uila a hiki ke hana i ke kinoea cyanogen chloride ʻawaʻawa.

Ion - Keʻano hoʻololi

ʻO ka ikaika - base anion - hoʻohana ʻia nā resins hoʻololi e hoʻololi me nā ion cyanide i ka hopena, e hoʻokō ai i ka wehe ʻana i nā ion cyanide. He kūpono ia no ka mālama ʻana i ka cyanide - loaʻa ka wai ʻino me ka haʻahaʻa a me ka haʻahaʻa haʻahaʻa, he kiʻekiʻe ka mālama ʻana, a hiki ke hoʻihoʻi i nā ion metala waiwai, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai.

Ka Hana Hana Ola Ola

Ma o ka hoʻohaʻahaʻa ʻana o nā microorganisms, ua hoʻololi ʻia nā mea cyanide i mea ʻawaʻawa ʻole a haʻahaʻa paha. He ʻoluʻolu a hoʻomau, akā pono ia i nā kūlana kaiapuni kūpono (e like me ka mahana, ka waiwai pH, etc.) a me ka manawa mālama lōʻihi. ʻO nā ʻano hana lapaʻau olaola maʻamau, ʻo ia ke ʻano o ka sludge hana a me ke ʻano biofilm.

Nā Kaʻina Hana Hoʻohui

I ka ʻike ʻana i ka paʻakikī o ka cyanide - loaʻa ka wai ʻōpala, ʻae ʻia ka hoʻohana ʻana o nā ʻenehana he nui. No ka laʻana, "ʻano alkaline chlorination + ion - exchange method", "electrolytic treatment method + ion - exchange method", "hydrogen peroxide oxidation method + biological treatment method", etc.
