Ụzọ ọgwụgwọ Oxidation

Usoro Alkaline Chlorination

N'okpuru ọnọdụ alkaline (nke na-abụkarị nke nwere pH dị n'etiti 10 na 11), a na-etinye oxidants dị ka chlorine ma ọ bụ sodium hypochlorite iji mee ka ihe cyanide ghara ịdị irè n'ime nitrogen na carbon Ọ dịghị ihe ọzọ dị na ya.

Usoro hydrogen peroxide oxide

N'okpuru ọnọdụ acidic ma ọ bụ alkaline, a na-eji hydrogen peroxide dị ka oxidant iji oxidize ihe cyanide n'ime nitrogen na mmiri. Ọ kachasị mma maka ịgwọ mmiri na-ekpofu mmiri na ihe dị elu nke cyanide, ma ọnụ ahịa ọgwụgwọ dị elu, ọ dị mkpa ka a na-achịkwa ọnọdụ mmeghachi omume nke ọma.

Usoro Oxidation Ozone

N'iji ihe ike oxidizing nke ozone, ihe cyanide na-eme ka ọ bụrụ ihe na-adịghị egbu egbu. Ngwọta ọgwụgwọ dị elu ma ọ nweghị mmetọ nke abụọ, mana ntinye ego akụrụngwa na ụgwọ ọrụ dị elu.

Fenton Oxidation usoro

A na-eji reagent Fenton mejupụtara hydrogen peroxide na nnu ígwè maka oxidation kemịkalụ iji mebie ihe cyanide nke ọma.

Usoro ọgwụgwọ Electrolytic

A na-eji mmeghachi omume oxidation electrochemical mebie ihe cyanide dị na mmiri mkpofu. N'okpuru ọnọdụ ụfọdụ, ion cyanide dị na mmiri mkpofu na-agbanye n'ime carbon dioxide, nitrogen, na amonia. Ọ dabara maka ịgwọ mmiri mkpofu na ion cyanide dị elu, mana ọ na-eri ike eletrik ma nwee ike imepụta gas cyanogen chloride na-egbu egbu.

Ion - Usoro mgbanwe

A na-eji ike - isi anion - mgbanwe resins gbanwere na ion cyanide na ngwọta, na-enweta mwepụ nke ion cyanide. Ọ dị mma maka ọgwụgwọ cyanide - nke nwere mmiri na-ekpofu mmiri na ọkara na nke dị ala, nwere nnukwu ọgwụgwọ ọgwụgwọ, ma nwee ike nwetaghachi ion metal bara uru, ma ọnụ ahịa ọgwụgwọ dị elu.

Usoro ọgwụgwọ ndu

Site na mmebi nke microorganisms, ihe cyanide na-agbanwe ka ọ bụrụ ihe na-adịghị egbu egbu ma ọ bụ dị ala. Ọ bụ enyi na enyi na gburugburu ebe obibi na-adigide, ma ọ na-achọ ọnọdụ gburugburu ebe obibi kwesịrị ekwesị (dịka okpomọkụ, uru pH, wdg) na ogologo oge ọgwụgwọ. Ụzọ ọgwụgwọ ndị mmadụ na-emekarị gụnyere usoro sludge arụ ọrụ na usoro biofilm.

Usoro ejikọtara

N'ihi mgbagwoju anya nke cyanide - nwere mmiri mkpofu, a na-anabatakarị ngwa ngwa nke ọtụtụ teknụzụ. Dịka ọmụmaatụ, "usoro chlorination alkaline + ion - usoro mgbanwe", "usoro ọgwụgwọ electrolytic + ion - usoro mgbanwe", "usoro hydrogen peroxide oxidation + usoro ọgwụgwọ ndụ", wdg Site na usoro jikọtara ọnụ, na - omimi ọgwụgwọ nke mmiri mkpofu nwere ike imeziwanye mma na-asọpụta.
