摘要：

In this work, Fenton's process was evaluated as an alternative treatment of swine effluent. In order to improve depuration, coagulation and biofiltration were integrated with Fenton's peroxidation. With the optimum loads of 750 mg/L of hydrogen peroxide and iron, this process was able to remove 72% of sCOD and lowering Aliivibrio fischeri luminescence inhibition to 65%. On the other hand, integration between Fenton's process and biofiltration removed 91% of sCOD. Whereas, after coagulation sCOD degradation reaches 86%. Regarding to luminescence inhibition, the treatment processes integration can decrease it to about 30%. Coagulation and biofiltration after Fenton's process proved to be able to remove dissolved iron in the treated effluent and thus overcoming Fenton's process major disadvantage. (c) 2021 Elsevier Ltd.
