Combination of catalytic ozonation and fungal bioremediation for treatment from effluent from the laminate production industry

This study characterized and evaluated the potential of a combination treatment strategies for removal phenolic compounds, color, ecotoxicity an effluent generated by laminated wood industry. The characterization sample pine lamination process collected in industry Southwest region state Paraná confirmed impact effluent, with emphasis on high content compounds (1,530 ±50 mg/L), color (2,159 ±30 units), significant acute toxicity (63% mortality microcrustaceans Artemia salina) low biodegradability (BOD/COD=0.53), which, if eventually released into receiving bodies, can cause irreversible harmful effects to aquatic microbiota. processes studied this work involved catalytic ozonation mediated ferrous material based steel scale biological Pleurotus Florida fungi, individual way sequentially integrated as follows: Catalytic ozonation>>biological vice-versa. best results were obtained applying sequence "catalytic process", which resulted reductions 96.2% soluble lignin concentrations, 93.3% units more than 99% reduction total phenols, addition rate A. salina (≈10%). In process, application before presents greater advantages because pre-decomposition recalcitrant chemical action ozonation, convert these biodegradable, facilitating remediation effluent.
