摘　　要：通过物理观察和气味辨识进行行业初筛并选取类比样品,对某非法倾倒的不明固体废弃物的物理特性、浸出毒性、成分组成及特征污染物进行全面测试分析,判断该废弃物属于镀锌行业酸洗污泥,进而对其进行毒性指标鉴别与危险性评估,判定其为非危险废物。通过本案例对不明来源固体废弃物的识别和鉴定程序、方法以及应把握的关键环节的试验与研究,得出的结论可为不明来源固体废弃物的鉴别与危险性评估提供借鉴。This paper conducts comprehensive test and analysis on the physical properties, leaching toxicity, composition and specific pollutants of the unknown solid waste that are illegally dumped ,after preliminary screening by physical observation and odor identification to select the control samples. The solid waste is judged as pickling sludge from the galvanizing industry. Then the identification of toxicity index and the hazardous assessment of the solid waste show that it is non-hazardous waste. The conclusion from the ex- periment and research on the procedure, method and the key points of identification of unknown solid waste provides useful reference for the identification and hazardous assessment of unknown solid waste.
