TOXICITY-BASED CRITERIA FOR THE EVALUATION OF TEXTILE WASTEWATER TREATMENT EFFICIENCY

摘要

Brazilian textile mills import wastewater treatment technologies, performances of which are generally evaluated only on a physicochemical basis. Thus, a battery of bioassay was used to evaluated the performance of an ozonation system to treat textile effluents. Comparative toxicological profiles for bacteria(Vibrio fischeri), algae(Scenedesmus subspicatus), daphnia(Daphnia magna), fish(Poecilia reticulata), and plants(soybean-Glycine max, rice-Oryza sativa, and wheat-Triticum aestivum), as well as genotoxie effects(Vicia faba micronucleus assay), are presented for both raw and ozonated textile effluents.
