【摘要】分析了水泥窑协同处置POPs污染土壤对烟气中污染物排放和熟料品质的影响,结果表明,SO2、NOx、HCl、Hg、As、Ni、Pb、粉尘、二(口恶)(口英)的排放量均低于工业大气污染物排放规定限制,与空白试验相比,水泥窑协同处置污染土壤过程中烟气中特征污染物排放量没有显著增加.水泥熟料化学成分满足相关规定,熟料产品质量达到相关标准,因此利用水泥窑协同处置POPs污染土壤是一种环境友好处理方式.%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, HC1, 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.
