【 摘 要 】

From the environmentalpoint of view, the textile sector is outstanding for the generation of largeamounts of biorecalcitrant effluents. In this paper the textile effluent biodegradability,both before and after its treatment with Fenton's Reagent, were compared bymeans of biologic tests. These tests showed that the Fenton treatment loweredthe biodegradabilty of practically all tested effluents, except one specificeffluent from a scouring bath of polyester fibers, which achieved a 93% CODremoval. This removal was due to a significant phase separation (oil/water).
