Characterization Studies

In this study, the wastewater of one of the cigarette factories in Izmir was characterized and treatability studies were done. The characterization studies of the wastewater showed that the COD, and the pH changes drastically. The chemical treatability studies of the influent wastewater were done by using Ca(OH)2, FeCl3 and Fenton Reagent. The optimum dose of FeCI3 was determined by jar tests. When using Ca(OH)2, the best flocculation, settling behaviour, and the highest COD removal occurred around pH 11. The optimum doses of Fenton Reagent (FeSO4 and H2O2) were determined. The supernatants of the previously chemically treated wastewaters were used for biological treatment. According to total COD removal efficiencies and the amount of sludge production during chemical treatment, FeCl3 was found to be the most economical and effective coagulant. Chemical treatment units were designed for a batch and a continuous system. The batch system has more advantages than a continuous system in this case.

The paper adopted Coagulation-Fenton Oxidation Method on treating the wastewater of 6-nitro-1,2 diazonium oxygroup naphthalene-4-sulfoacid production process (i.e. 6-nitry wastewater), introduced the treatment effect of the combined technology used on 6-nitry wastewater, and studied the factors influencing the treatment effect, to determine the reasonable parameters of the technology on treating 6-nitry wastewater. The results showed that Using polyaluminium chloride (mass fraction 2%) as flocculant for treating 6-nitry wastewater, the COD removal rate reached up to 48.7%; Making Fenton reagent oxidation treatment on coagulation yielding water, under the best conditions for solution acidity controlled at pH3 or so, in the 100 mL wastewater, 30% hydrogen peroxide was 5.0 mL, 0.5 mol/L ferrous sulfate solution was 4.0 mL, reaction time was 60 min, the COD removal rate could reach 98% or more.

Fenton reagent was selected as oxidizers for the oxidation and degradation of cafeteria wastewater. The treatment effects were evaluated by the changes of COD and BOD5 parameters. The effects of Fenton reagent ratio, dosage of FeSO4•7H2O and pH value on wastewater treatment under normal temperature and pressure were investigated, the oxidation regularity is initially discovered as well. Orthogonal experiments were designed to optimize the processing conditions based on the single affected factor. The optimized controlling conditions for Fenton reagent treatment process is FeSO4•7H2O=1mmol/L, pH=3, H2O2/Fe2+=3.5:1, reaction time=60min. With Fenton reagent treatment the COD removal ratio was raised up to 94%. Compared with biological process, it saved land occupation and was more suitable for regions which lacked of land space.
