Phenolic Compounds in Water: Sources, Reactivity, Toxicity and ...
WebAbstract. The toxicity of phenol even at low concentrations in industrial effluents is high enough to meet its needs for separation. In this paper, a review will be carried out on the traditional techniques and recent advances in the separation of phenol from its contaminated streams. WebPhenol (hydroxybenzene) is the simplest of a group of similar organic chemicals, which includes cresols, xylenols, and catechols. Phenol itself is a common ingredient of disinfectants. In drinking water, low-level phenolic concentrations impart a foul taste and odor, especially upon chlorination. css 限制文字行数

Web23. dec 2024 · The contamination of water resources is a serious environmental concern. The water quality has been constantly decreasing due to the existence of different pollutants such as dyes, synthetic hormones, phenol, and pharmaceuticals [1, 2].Phenol and phenolic compounds are one of the most persistent toxic organic pollutants discharged in … WebIn the ozonation process, the phenol degradation in wastewater undergoes a low mass transfer mechanism. In this study, ozonized packed bubble column reactor was designed and constructed to remove phenol. The reactor’s inner diameter and height were 150 and 8 cm, respectively. WebThe results show that a very high percentage (above 80%) of the phenolic fraction below 500 D is removed by the methanogenic process whereas the phenolic fractions above 1,000 D are significantly adsorbed on bentonite; the 8-day activated sludge post-treatment allows an additional removal of about 40% of total filtered phenolic compounds. css 集金代行
