Ocean dumping of sewage sludge has been prohibited since 2012. Therefore, various methods to recycle sewage sludgeare studied And the adsorption is used to remove mercury released to the atmosphere. Chlorine and Iodine impregnatedadsorbent is used to remove mercury in the flue gas. In our study, we studied the method to recycle sewage sludge andbrewers grain as an adsorbent to remove mercury. Thermal treating time and temperature, and mixing ratio of sewage sludgeand brewers grain are discussed for the preparation of adsorbent. According to the results, the optimal condition oftemperature, time and mixing ratio was 400oC, 45min and 7:3 of sewage sludge/brewers grain, respectively. Theimpregnation of I is needed to keep the concentration of KI above 7%. I and Cl are dispersed uniformly in prepared adsorbent.
