Phenolic tebchaw muaj nyob rau hauv cov dej ntws ntawm ntau yam kev lag luam xws li roj refining, petrochemicals, kws tshuaj, coking operations, resin manufacturing, plastics, paint, pulp, paper, and wood. khoom [1–3].
Kev lag luam effluent muaj phenol?
Phenol yog siv dav hauv kev lag luam sib txawv xws li tshuaj lom neeg kev lag luamqhov twg nws yog siv rau hauv kev tsim khoom ntawm lwm yam derivatives xws li alkylphenols, cresols, aniline thiab resins [21]. Nws daim ntawv thov hauv kev lag luam roj thiab roj thiab thee kuj tseem ceeb [1].
Cov khoom lag luam twg muaj phenol?
Phenol muaj nyob rau hauv ntau cov khoom siv uas tau nqos, rubbed los yog ntxiv rau ntau qhov chaw ntawm lub cev. Cov no suav nrog tshuaj pleev, pob ntseg thiab qhov ntswg dauv, tshuaj kho mob khaub thuas, tshuaj ntxuav qhov ncauj, gargles, tshuaj txhuam hniav, tshuaj txhuam hniav, caj pas lozenges thiab tshuaj tua kab mob.
Yuav ua li cas yog siv rau kev sib cais ntawm phenols los ntawm industrial pov tseg effluent?
Distillation/evaporation Muaj ntau yam evaporation/distillation xaiv tau rau kev sib cais ntawm phenols ntawm cov dej khib nyiab. Lawv siv cov txheeb ze volatility ntawm qee cov phenols los ntxuav dej. Cov txheej txheem distillation feem ntau muaj cov nqi hluav taws xob siab thiab feem ntau siv tau rau cov phenol siab nkaus xwb.
Phenol siv li cas hauv kev lag luam?
Hauv kev lag luam, phenol yog siv ua cov khoom pib los ua cov yas, cov khoom tawg xws li picric acid, thiab tshuaj xws li tshuaj aspirin. … Cov khoom sib xyaw ntawm phenols (tshwj xeeb tshaj yog cov cresols) yog siv los ua cov khoom hauv cov khoom siv ntoo xws li creosote.
