Abstract:Exhaust emission of pollutants and cement quality were studied in the cement kiln disposal of POPs contaminated soil. Results showed that pollutants emission of SO2, NOx, HCl, Hg, As, Ni, Pb, dust and dioxin in the treatment process were lower than the industrial air emissions standards. Compared with the incineration process without POPs contaminated soil, tested targets in exhaust gas including acid gas, dioxin and heavy metals were not significantly increased in cement kiln system of co-processing POPs contaminated soil. And the chemical composition of cement clinker and its quality could meet the relevant standards. The treatment of POPs contaminated soil as alternative raw material for cement kiln could be an environment-friendly approach.
