【Abstract】 The removal of COD from wastewater by sludge activated carbon was studied. The effects of the ratio of sludge activated carbon dosage to wastewater volume, wastewater pH, temperature and adsorption time on COD removal were studied by single factor experiment, and the optimum process conditions for COD removal were optimized by orthogonal experiment. The results show that when the ratio of sludge activated carbon dosage to wastewater volume is 20 g·L^-1, the pH of wastewater is 7, the temperature is 28 ℃, and the adsorption time is 60 min, the removal efficiency of sludge activated carbon to wastewater COD is the best, and the removal rate can reach 76.59%.更多还原
