Electrochemically Assisted Photocatalytic Degradation of Pesticide Wastewater by Using the Self-Made Pilot Plant

Abstract:

The RuO₂/TiO₂ photocatalyst was prepared by the dip-coating method, which use Ti mesh as the carrier and titanium tetrachloride and ruthenium chloride as the raw materials. In the same way, the mutil-walled carbon nanotubes (MWCNTs) air cathode was synthesized by using the stainless steel mesh as the supporter and the MWCNTs, manganese dioxide and Polytetrafluoethylene (PTFE) as the Substrate. The level of chemical oxygen demand (COD) and chroma are valuable reference index in the photoelectrocatalytic degradation of practical pesticide wastewater by the self-made pilot plant. The real pesticide wastewater is the typical high concentration organic wastewater and COD_cr concentration is above 10000mg/L. Practical running showed that the treated pesticide wastewater quality can meet the third grade standard for discharge of pollutants of the integrated wastewater discharge standard (GB8978-1996). The results showed that the removal efficiency of COD and decoloration efficiency were above 90.41% and 78.62%, respectively.
