Treatment of Secondary Sedimentation Tank Wastewater by Fenton Oxidation-Neutralization-Coagulation Sedimentation

Shan Chen, Bin Liu, Cheng-yuan Hu


In this paper, the CODCr index is used as the detection item, and the wastewater from the secondary clarifier of a sewage treatment plant is treated by "Fenton oxidation-neutralization-coagulation sedimentation" method. The results showed that the removal rate of CODCr reached 73.4% by "Fenton oxidation-neutralization-coagulation precipitation" method. It can be seen that this method can make the wastewater discharge up to the standard and provide data support for better treatment of industrial wastewater in engineering.
