Study on Treating Technology of Cr⁶⁺Wastewater by Direct Current (dc) Electro-Coagulation Method

Abstract:

Cr⁶⁺wastewater treatment by the self-designed the electric flocculation device has been investigated. This paper analyzed the factors such as the reaction time, reaction voltage, Electrode current, the electrolyte concentration, as well as Reaction pH on the effect of Cr⁶⁺wastewater treatment. Comparison of previous studies: Under neutral condition, reaction current was 4.5A,reaction voltage was 25V, electrolytic time was 25 minutes. After processing Cr⁶⁺down to concentration of 0.02mg/l, which reached the national sewage discharge standards (GB8978-2002).
