Txheej txheem cej luam ntawm Lub Ntsiab Cai

Raws li Fenton cov tshuaj tiv thaiv mechanism, Fenton catalytic oxidation cov cuab yeej ua ke nrog ntau lub zog xws li heterogeneous catalysis, fluidized txaj hu, thiab adsorption -coagulation kom ua tiav cov pa phem degradation. Lub hauv paus ntsiab lus tseem ceeb tau muab faib ua peb kauj ruam:
1. Homogeneous Oxidation Reaction
Nyob rau hauv acidic tej yam kev mob (pH tus nqi: 2.5–3.5), ferrous ions (Fe²⁺) catalyze hydrogen peroxide (H₂O₂) los pib cov tshuaj tiv thaiv saw, sai sai tsim hydroxyl radicals (·OH). Nrog rau oxidation - txo qhov peev xwm siab li 2.8V, hydroxyl radicals muaj zog oxidizing zog heev. Lawv tuaj yeem tsis yog - xaiv ua txhaum cov qauv ruaj khov ntawm cov pa phem xws li C-C daim ntawv cog lus thiab benzene rings, decomposing refractory organic tshuaj rau hauv me me - cov tshuaj molecule (piv txwv li, carbon dioxide thiab dej) kom paub qhov tsis zoo ntawm cov pa phem. Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no: H₂O₂ + Fe²⁺ → Fe³⁺ + OH⁻ + OH

2. Heterogeneous Catalysis thiab kev sib cuag zoo
Cov khoom siv yog nruab nrog cov khoom siv fluidized xws li hloov kho cov pa roj carbon monoxide thiab cov khoom ceramic. Lub Fe³⁺ tsim thaum lub sij hawm cov tshuaj tiv thaiv adheres rau saum npoo ntawm cov cab kuj nyob rau hauv daim ntawv ntawm crystals, tsim ib tug heterogeneous catalytic system. Cov txheej txheem no tsis tsuas yog txuas ntxiv lub neej kev pab cuam ntawm catalyst, tab sis kuj tseem txhawb kev tsim cov hydroxyl radicals los txhim kho cov tshuaj tiv thaiv.
