摘要

This paper represents a first approach in the study of photoreactor selection to treat industrial wastewater using solar photo-Fenton. In this context, simulated textile industry effluent containing a mixture of four dyes at different initial dissolved organic carbon (DOC) concentrations (45, 90, 180 and 270 mg/L) was treated by using three different solar reactor geometries: (i) tubular (5 cm diameter) provided with compound parabolic collector (ii) tubular (5 cm diameter) provided with flat collector and (iii) open channels forming raceway ponds with two liquid depths (5 and 15 cm). For comparison purposes, mineralisation percentages over 75% and chronic toxicity reduction were set as treatment goals. Regardless of the initial DOC concentration, negligible differences in terms of treatment time and hydrogen peroxide consumptions were found between the flat collector and compound parabolic collector photoreactors. Conversely, the treatment in the raceway pond reactors always resulted in higher values. In spite of this, when the photoreactors were compared in terms of treatment capacity (mg of DOC removed/m(2) min) the raceway pond reactor at 15 cm of liquid depth presented the best results, with values as much as two or three times higher than those of the tubular reactors, except for the wastewater with 270 mg of DOC/L for which the raceway pond reactor at 5 cm liquid depth became the best option. When the treatment capacity is modified to include the photoreactor investment (mg of DOC removed/(sic) m(2)) the differences between the raceway pond reactor at both liquid depths and the photoreactors with solar collectors increased by as much as two orders of magnitude, which demonstrates the potential application of the former for the treatment of industrial wastewater by solar photo-Fenton.
