Abstract: COD from heavy oil wastewater was removed by activated carbon on room temperature. It was showed that removal efficiency of COD reached above 65% under the condition of 50min of adsorption time, 7 of pH, 6g of the used activated carbon and 1kg of activated carbon was used to treat 1m3 of heavy oil waste water.

Abstract: For heavy oil wastewater from Henan oilfield, removal of silica has been investigated under the condition of different flocculants and reaction time when magnesia has been used as a desilica agent. An optimum method has been determined by conditional experiments, 63% of silica could be removed.
