摘要(Abstract)：

工业危险废液的热值准确测定对于保障热解处置工艺的正常运行至关重要。多相低热值工业危险废液不易燃烧、多相共存、成分难辨，故难以用氧弹直接燃烧法准确反映热值。今基于工业危废液的特性，提出对工业危废液分相测定热值，即固相残余物直接燃烧结合含水馏出物间接估算的总思路。针对含水馏出物成分复杂难辨的特性，提出了基于气相色谱-质谱法对工业危险废液成分化学式及物质量相对比例的辨识，通过推导统一化学计量式计算热值的间接估算法。结果表明该方法估算热值误差小于6%，核算同分异构体对热值的影响误差较小。针对危废液热值的日常监控，可选用COD为热值关联表征参数。选取7种不同行业危废液的热值实测及计算，验证了方法的普适性。
