Abstract

Abstract

To systematically grasp the pollution characteristics and environmental risks of incineration residues, their chemical and mineral composition and pollution characteristics of heavy metals and chlorides were analyzed. The risk assessment code (RAC) and synthesis toxicity index (STI) were used to evaluate the environmental risks of heavy metals. Results showed that grate furnace fly ash presented characteristics of high calcium and chlorine, in which Cu, Zn and Cd were mainly in the F2 state, and leaching toxicity of Pb exceeded the limit, while fluidized bed fly ash was rich in SiO₂ and Al₂O₃_, with a Cl content of 5.79%. Hazardous waste and medical waste fly ash presented the same characteristics of high sodium and chlorine, in which Zn, Cd and Ni were mainly in the F1 state, but the difference was that the leaching toxicity of Cu of the former exceeded the limit, while the later was Zn, existing in the form of ZnCl₂. Both hazardous waste and medical waste incineration slag were rich in SiO₂, Al₂O₃ and Fe₂O₃ and with a Cl content of 3.27%, and their Cu and Ni contents reached 7525.5, 991.4 mg/kg and 4168.8, 628.2 mg/kg, respectively. Risk assessment indicated that the STI of grate furnace, fluidized bed, hazardous waste and medical fly ash were also all in moderate or high risk levels, and RAC and STI of all kinds heavy metals in hazardous waste and medical waste incineration slag were in low or moderate risk level. Cu or Pb in incineration residues had a negative impact on human health, and Cd and Cr were both at high carcinogenic risk levels.
