Abstract

In this paper, sludge bio-carbon was prepared by pyrolysis and carbonization of sewage sludge from the first sewage treatment plant and the second sewage treatment plant of A city. The physicochemical properties and cadmium adsorption properties were characterized. The results show that the optimum activation temperatures of sludge in different sewage treatment plants are different. The optimum activation temperature of the sludge in the first sewage treatment plant is 300 centigrade, and the sludge in the second sewage treatment plant is 400 centigrade. In the first sewage treatment plant, the adsorption equilibrium of cadmium by bio char is formed about 7h later. The adsorption equilibrium of cadmium by bio char is formed about 5h later in the second sewage treatment plant. The adsorption capacity of bio char to cadmium increases with the increase of pH value in the sewage plant.
