Abstract
High-concentration p-chlorophenyl isocyanate wastewater was treated with catalytic wet oxidation technology in a continuous fixed-bed bubble column reactor.The experimental results indicate that the catalyst CuO-ZrO2-CeO2/TiO2 showed high activity.The process parameters,such as reaction temperature, reaction pressure,space velocity,volume ratio of oxygen to wastewater and the pH of wastewater,were measured experimentally and the results show that the CODCr removal rate can reach 96.9% under optimal reaction conditions when the temperature is 240℃,pressure is 6.5MPa,space velocity is 2.0 h-1,the volume ratio of oxygen to wastewater is 230,and the pH is 8.
