Kodi njira zochiritsira zodziwika bwino za cyanide - zomwe zili ndi madzi otayira ndi ziti?

Pakadali pano pakukweza milingo yosamalira zachilengedwe komanso zofunikira kwambiri, madera ambiri omwe amagwiritsa ntchito cyanides amapanga zinyalala zambiri zovulaza. Ngati sizigwiritsidwa ntchito bwino, zitha kuyika pachiwopsezo thanzi la anthu. Kuti tikwaniritse zolinga ziwiri za kusataya zinyalala ndi kusawononga, njira zobwezeretsanso zitha kugwiritsidwa ntchito kuti tithetse vutoli.

Njira ya Acidification

Mfundo yaikulu ya njira iyi ndi kuwonjezera sulfuric acid ku cyanide - madzi otayirira monga Sodium cyanide wastewater ndikusintha pH kufika pa 1.5. Izi zimasintha CN - kukhala HCN. Popeza kutentha kwa HCN kumakhala kochepa kwambiri, 26.5℃ yokha, kumatha kutuluka mu yankho kutentha kwa chipinda. Mpweya wa HCN womwe watuluka umalowetsedwa mu absorber ndikuyamwa ndi yankho la alkaline (sodium hydroxide kapena calcium hydroxide solution). Zotsatira zake, yankho la 20% - 30% cyanide limapezedwa, lomwe lingathe kubwezeretsedwanso.

Ion - Kusinthana Njira

Ma resini osinthira a Anion ali ndi mphamvu yayikulu pa ma ayoni osiyanasiyana achitsulo - cyanide complex omwe ali mu madzi otayira a cyanide. Kudzera mu njira zothira ndi kusungunula, ma Cyanide ndi zitsulo zamtengo wapatali m'madzi otayira zimatha kuchotsedwa. Ubwino wa njira iyi ndikuti madzi oyera ndi abwino komanso okhazikika. Komabe, ma resini osinthira a anion ali ndi tinthu tating'onoting'ono tating'ono komanso mphamvu zosakwanira zamakanika. Kuphatikiza apo, njirayi ndi yovuta kwambiri, yokhala ndi zovuta zambiri zogwirira ntchito komanso ndalama zambiri.

Njira Yopangira Carbon Adsorption

Mpweya wopangidwa ndi activated uli ndi mawonekedwe olemera a microporous ndi pamwamba pa hydrophobicity, ndipo uli ndi mgwirizano wamphamvu kwambiri wa zinthu zapoizoni m'madzi. Chifukwa chake, njira ya activated carbon adsorption nthawi zonse yakhala imodzi mwa njira zothandiza kwambiri zochotsera zinthu zomwe zili ndi poizoni m'madzi. Mphamvu ya adsorption ya carbon activated makamaka imadalira ma pores ake ambiri amkati ndi malo akuluakulu enieni.

Pofuna kuonetsetsa kuti ma cyanide monga Sodium Cyanide sanatuluke, oyang'anira nthawi zonse amayesa ubwino wa madzi kuti adziwe kuchuluka kwa kuipitsidwa kwa cyanide. Ngati kuli kofunikira, malo ochenjeza amakulitsidwa. Oyang'anira onse komanso ogwira ntchito yochizira ayenera kuvala magolovesi oteteza omwe sakhudzidwa ndi mafuta a rabara.

Pomaliza, kuchiza ndi kubwezeretsanso zinyalala za Cyanide moyenera ndikofunikira kwambiri poteteza chilengedwe komanso kusunga chuma. Mwa kugwiritsa ntchito njira izi ndikuwonetsetsa kuti zikuyang'aniridwa bwino, titha kuchepetsa zotsatira zoyipa za cyanide - zomwe zimakhala ndi zinyalala pa chilengedwe ndi thanzi la anthu.
