“…The photocatalytic process partially transforms the refractory organic compounds into intermediate species, which are further degraded and mineralized by biodegradation. So far, ICPB has been successfully applied to the degradation of various refractory organic pollutants, and has significantly improved the degradation and mineralization efficiency of these compounds 13‐15 . Our group previously applied the ICPB method to the degradation of methylene blue under UV light and achieved good degradation performances, also superior to those of the photocatalysis and biodegradation systems alone 16 .…”

BACKGROUND Intimately coupled photocatalysis and biodegradation (ICPB) is a novel wastewater treatment technology with potential applications in the degradation of bio‐recalcitrant compounds. Although visible light has some advantages over UV light in the ICPB technology, it has never been used to treat 2,4,6‐trichlorophenol (2,4,6‐TCP)‐contaminated wastewater with this approach. RESULTS TiO2/sponge composites with good photocatalytic activity under visible light were prepared and used as biofilm supports to develop a novel ICPB system. The latter showed highly efficient degradation properties and could mineralize 2,4,6‐TCP, with performances superior to those of the individual biological and photocatalytic systems. The removal of 2,4,6‐TCP using the ICPB system reached almost 100% after 4 h, whereas the mineralization rate approached 83% after 12 h. The key feature of the presented ICPB method is that photocatalytic reactions can occur after detachment of biofilms from the outer surface of the composite, and the resulting photocatalytic products are biodegraded by the protected biofilms inside the composites. The interior of the composites exhibited a marked enrichment in Acinetobacter, Methylophilus, Pseudomonas, Acidovorax and Flavobacterium species, which played an important role in the ICPB system. CONCLUSIONS This study introduces a new bio‐photocatalytic degradation system and provides insight into the mechanism of chlorophenol‐contaminated wastewater treatment using ICPB. © 2022 Society of Chemical Industry (SCI).

Phenol is a harmful substance that can be present in many industrial wastewaters. Chemical phenol removal is feasible, but the procedure is challenging and expensive. Biological phenol removal is possible under mild conditions with enzymes. Phenol hydroxylase is the main enzyme for phenol removal. In this study, phenol hydroxylase was induced from filamentous fungus Aspergillus niger. The results have shown that it is possible to use Aspergillus niger as a phenol hydroxylase source, but the enzyme has activity in limited temperature and pH conditions. The optimal working conditions of the enzyme are 30 °C and pH 6.5. The enzyme has moderate storage and thermal stability, and various compounds inhibit it.

This is a review of the literature published in 2018 on topics related to hazardous waste management in water, soils, sediments, and air. The review covers treatment technologies applying physical, chemical, and biological principles for contaminated water, soils, sediments, and air.Practitioner points The management of waters, wastewaters, and soils contaminated by various hazardous chemicals including inorganic (e.g., oxyanions, salts, and heavy metals), organic (e.g., halogenated, pharmaceuticals and personal care products, pesticides, and persistent organic chemicals) was reviewed according to the technology applied, namely, physical, chemical and biological methods. Physical methods for the management of hazardous wastes including adsorption, coagulation (conventional and electrochemical), sand filtration, electrosorption (or CDI), electrodialysis, electrokinetics, membrane (RO, NF, MF), photocatalysis, photoelectrochemical oxidation, sonochemical, non‐thermal plasma, supercritical fluid, electrochemical oxidation, and electrochemical reduction processes were reviewed. Chemical methods including ozone‐based, hydrogen peroxide‐based, persulfate‐based, Fenton and Fenton‐like, and potassium permanganate processes for the management of hazardous were reviewed. Biological methods such as aerobic, anaerobic, bioreactor, constructed wetlands, soil bioremediation and biofilter processes for the management of hazardous wastes, in mode of consortium and pure culture were reviewed.
