The degradation of wine distillery wastewaters by aerobic biological treatment has been investigated in a batch reactor. The evolution of the chemical oxygen demand, biomass and total contents of polyphenolic and aromatic compounds was followed through each experiment. According to the Contois model, a kinetic expression for the substrate utilization rate is derived, and its biokinetic constant is evaluated. The final effluents of the aerobic biological experiments were oxidized by Fenton's reagent. The evolution of chemical oxygen demand, hydrogen peroxide concentration and total contents of polyphenolic and aromatic compounds was followed through each experiment. A kinetic model to interpret the experimental data is proposed. The kinetic rate constant of the global reaction is determined.

Degradation of olive mill wastewater (OMW) by means of two chemical oxidation processes (Fenton's reagent and ozonation) and their consecutive treatments with aerobic microorganisms have been studied. Fenton's reagent treatment moderately reduces COD and to a greater extent the polyphenolic compounds. Ozonation contributed to low conversion of COD and moderate reduction of polyphenols. The aerobic biological treatments degrade to values higher than 70% and 90% for COD and polyphenolic compounds, respectively. A kinetic study has been carried out in each process, determining the representative kinetic parameters of each model.

The aim of this study was to investigate the PAHs removal efficiency in coking plant contaminated soil when disposed by different oxidants with different dosages (hydrogen peroxide, Fenton’s reagent, modified Fenton’s reagent, potassium permanganate, activated sodium persulfate) and the PAHs distribution characteristics in removing parts, soil residue parts, recycling parts and supernate after oxidation reactions. Analyzed the variation characteristics of soil properties (pH and soil temperature) when used different oxidants in oxidation reactions process, screened out the effective and safe remediation oxidants. The research results indicated that the potassium permanganate has the best remediation ability and undemanding reaction conditions than other oxidants. The contaminant which be volatilized into surrounding environment was rarely when disposed by potassium permanganate in remediation process. Consequently, selecting potassium permanganate as remediation oxidant to treat PAHs in coking plant contaminated soils was the best choice.

AbstractThe degradation of chemicals in water is commonly performed using chemical oxidation. In case of refractory compounds, hydroxyl radicals have to be involved for their degradation. Several systems may be used to generate OH°, such as the ferrous iron-hydrogen peroxide system (Fenton’s reagent). However, when this reagent is prepared by mixing the two constituents, the oxidation of an organic compound is difficult to control and the ferrous iron regeneration is limited. So, very recently, electrochemical systems have merged that allow the electrochemical production of ferrous iron and/or hydrogen peroxide, thereby allowing the generation of OH°. In this paper, the efficiency of a simple electro-Fenton system in degrading chemicals in acidic medium is shown. Atrazine was chosen as a model organic compound. In addition, the electrochemical system compared favorably with the classical Fenton’s reagent under similar conditions, as it allowed a more thorough oxidation of atrazine.
