jaue2015069: The Efficiency Analysis of Helianthin Wastewater Treatment by Photocatalytic Oxidation Technology with Cu2O

Abstract

Helianthin wastewater was oxidized by Cu2O as photo catalyst under the sunlight. The results indicated that Cu2O had great photocatalytic performance for helianthin wastewater degradation: COD concentration of helianthin wastewater decreased from 392.05 mg/L to 17 mg/L in 6h, and the removal rate of helianthin was 95.7%; COD removal rate decreased a little with rising concentration of helianthin wastewater, and COD removal rate decreased to 87% when COD concentration of helianthin was 1264.2mg/L. The optimal dosage of Cu2O is 0.6g Cu2O/g helianthin for degrading helianthin.
