Study on Pretreatment of P-Tertt-Butylphenol Formaldehyde Resin Synthesized Wastewater

In this paper, pretreating p-tertt-butylphenol formaldehyde resin synthesized wastewater has been carried out by the combined techniques of the ferric-carbon micro-electrolysis (abbreviated as FCME) and the Fenton reaction. The result shows that when the COD of the wastewater is between 3350~8370mg/L, pH=2.0 and the reaction time of FCME is 120 minute, the removal of COD is above 48% though the FCME. The effluent of FCME was dosed 2.4ml/L H₂O₂(30%), and it had reacted 60 minutes at normal temperature(20~30°C) as Fenton reaction, the removal of COD exceeds 83% and B/C is increased from original under 0.05 to 0.35. Though this pretreatment, bio-treated the p-tertt-butylphenol formaldehyde resin synthesized wastewater is possibility.
