The objective of this work was to characterize the delignification effluent originating from the delignification industry and evaluate the combination of the fungus and photocatalytic process (TiO(2)/UV system) for the treatment of this effluent. The delignification effluent has proven harmful to the environment because it presents high color (3516 CU), total phenol (876 mg/L) and TOC (1599 mg/L) and is also highly toxic even in a low concentration. The results of photocatalysis were 11%, 25% and 13% higher for reductions in color, total phenol and TOC, respectively. The combined treatments presented benefits when compared to the non-combined treatments. Fungus and photocatalysis in combination proved to be the best treatment, reducing the color, total phenol, toxicity (inhibition of Escherichia coli growth) and TOC by 94.2%, 92.6%, 4.9% and 62%, respectively.
这项工作的目的是对源自脱木素工业的脱木素废水进行特性分析，并评估真菌与光催化过程（TiO₂/UV系统）相结合处理该废水的效果。事实证明，脱木素废水对环境有害，因为其具有高色度（3516 CU）、总酚含量（876 mg/L）和总有机碳含量（1599 mg/L），并且即使在低浓度下也具有高毒性。光催化处理在降低色度、总酚和总有机碳含量方面的效果分别高出11%、25%和13%。与非联合处理相比，联合处理具有优势。事实证明，真菌与光催化相结合是最佳处理方法，可分别将色度、总酚、毒性（对大肠杆菌生长的抑制）和总有机碳含量降低94.2%、92.6%、4.9%和62%。
