摘　　要：有机化工行业废盐具有产量大、成分复杂、含有毒有机物等特点,其资源化成为目前行业可持续发展的瓶颈。某化工企业以甲苯和硝酸为原料,生产混硝基甲苯。甲苯硝化过程中的废水采用四效蒸发后成浓缩液,后至焚烧炉焚烧处理,炉渣为焚烧盐。根据国家关于危险废物鉴别的相关技术规范和导则,结合项目本身的原辅料、生产工艺、产污环节及废物处置情况,对进入焚烧炉处理的浓缩液和焚烧后产生的焚烧盐同步进行危险特性识别和鉴别,并提出了相关建议和要求,为焚烧盐的科学处置和资源化利用提供技术依据,同时可为同类废盐的危险特性鉴别工作提供参考。Waste salt in the organic chemical industry has the characteristics of large output,complex composition,and toxic organic com-pounds,and its resource utilization has become a bottleneck for the sustainable development of the industry.A certain chemical enterprise produces mixed nitrotoluene using toluene and nitric acid as raw materials.The wastewater from the nitration process of toluene is evaporated into a concen-trated solution using four effect evaporation,and then sent to the incinerator for incineration treatment.The slag is incinerated salt.According to the relevant technical specifications and guidelines on hazardous waste identification in the country,combined with the raw materials,production pro-cesses,pollution generation links,and waste disposal situation of the project itself,the hazardous characteristics of the concentrated liquid entering the incinerator for treatment and the incineration salt generated after incineration are identified and distinguished synchronously.Relevant sugges-tions and requirements are put forward to provide technical basis for the scientific disposal and resource utilization of incineration salt,and to pro-vide reference for the identification of hazardous characteristics of similar waste salt.
