Abstract
Highlights: Black-Right-Pointing-Pointer We firstly report a real pulp mill wastewater treatment by solar photo-Fenton in a CPC reactor. Fenton reagent experiments were tested firstly. Black-Right-Pointing-Pointer Solar photo-Fenton presents excellent ability to treat the pulp mill wastewater. Black-Right-Pointing-Pointer Experimental conditions were optimised. Black-Right-Pointing-Pointer Biodegradability and toxicity tests (respirometry assays and BOD{sub 5}/COD ratio) were performed during the wastewater treatment. Black-Right-Pointing-Pointer A way to reduce the economic and environmental impact was evaluated. - Abstract: This work reports on pulp mill wastewater (PMW) tertiary treatment by Fenton (Fe{sup 2+}/H{sub 2}O{sub 2}) and solar photo-Fenton (Fe{sup 2+}/H{sub 2}O{sub 2}/UV) processes in a pilot plant based on compound parabolic collectors (CPCs). Solar photo-Fenton reaction is much more efficient than the respective dark reaction under identical experimental conditions. It leads to DOC mineralisation, COD and total polyphenols (TP) removal higher than 90%. The solar photo-Fenton experiment with 5 mg Fe L{sup -1} reaches 90% of DOC mineralisation with 31 kJ L{sup -1} of UV energy and 50 mM of H{sub 2}O{sub 2}. The initial non-biodegradability of PMW, as shown by respirometry assays and BOD{sub 5}/COD ratio, can be changed after a solar photo-Fenton treatment. Experiments with 20 and 50 mg Fe L{sup -1} revealed that solar
