Helianthin wastewater was oxidized by Cu 2 O as photocatalyst under the sunlight . The results indicated that Cu 2 O had great photocatalytic performance for helianthin wastewater degradation:COD concentration of helianthin wastewater decreased from 392.05 mg/L to 17 mg/L in 6 h, and the removal rate of helianthin was 95 .7%;COD removal rate decreased a little with rising concentration of helianthin wastewater , and decreased to 87%when COD concentration of helianthin was 1 264.2 mg/L.The optimal dosage of Cu 2 O was 0.6 g Cu2 O/g helianthin for degradating helianthin .
