摘要: Wastewater from textile industry usually undergoes activated sludge biotreatment ahead of refining treatments, final discharge or reuse. To identify the most effective bioreactor typology for secondary treatment a wastewater resulting Biella district (Italy), four pilot units characterized by different configuration and fluid dynamics (i.e., Bioflotation®, Fixed Bed Biofilm Reactor (FBBR), flow-jet aeration standard aerobic reactors) were operated in parallel, inoculated with same microbial consortium fed identical streams discharged wet processes industy. COD, TC non-ionic surfactants monitored effluents compared bioreactors working under continuous mode cultivable heterotrophic microorganisms prevailing each them isolated as end study. The results demonstrated that air supply system greatly influenced efficiency which reached highest value case Bioflotation® FBBR technology. A highly specialized bacterial biomass mostly composed strains Pseudomonas, Stenotrophomonas Ochrobactrum genera was such reactors, thus suggesting direct correlation between reactor configuration, decontamination performances composition exist.
