Abstract

Abstract This paper studies the mechanism of arsenic adsorption by different adsorbents during sludge incineration. The mechanism of arsenic adsorption in the sludge incineration process was studied in a vertical furnace. The arsenic adsorption performance of CaCO3 and Fe2O3 at different temperatures was studied. When the temperature is 900°C, the overall adsorption performance is the best. Therefore, the arsenic adsorption performance of Al2O3, molecular sieve and its metal load at 900°C is further studied for comparison. The research results show that: the optimal adsorption temperature of CaCO3 is 900°C, the optimal adsorption temperature of Fe2O3 is 800°C, and the adsorption performance of CaCO3 is better than Fe2O3. Ca2+: Al3+=0.5 and Fe3+: Al3+=0.4 are close to the adsorption saturation state when Al2O3 adsorbs arsenic at 900°C. When the molecular sieve adsorbs arsenic at 900°C, the adsorption effect is best when the molecular sieve is 10X, Ca2+: Al3+=0.8 and Fe3+: Al3+=0.6 are close to the adsorption saturation state.
