Solid waste refers to solid or semi-solid waste produced during production, living and other activities, including industrial waste, household garbage, agricultural waste, and the like. The solid waste may contain some components with dangerous characteristics, such as inflammability, explosiveness, corrosion, toxicity, radioactivity, etc., which pose a threat to the environment and human health, so that the solid waste needs to be identified to determine whether the solid waste belongs to the dangerous waste, so that corresponding management measures are taken;
reactivity refers to the characteristic that solid waste is unstable, is highly susceptible to severe chemical reactions, or reacts with water, or forms an explosive mixture, or generates toxic gases, under normal conditions. The reactive hazardous waste can cause accidents such as fire, explosion, poisoning and the like in the transportation, storage, treatment and disposal processes, and serious environmental pollution and casualties are caused. Therefore, the identification of the reactivity of solid waste is an important content for hazardous waste identification.
Currently, the identification of the reactivity of solid wastes is mainly based on the national standard hazardous waste identification standard reactivity identification (GB 5085.5-2007), which prescribes identification standards and experimental methods of reactive hazardous wastes. The experimental method in the standard mainly comprises the following steps:
impact sensitivity measurement: the sensitivity of the sample to mechanical impact is determined.
-test of flammable or toxic gases upon water: it was determined whether or not a severe chemical reaction occurred after the sample was mixed with water, and a large amount of flammable gas or toxic gas was emitted.
Cyanide and sulfide content determination: it is determined whether the sample is capable of decomposing under acidic conditions to produce hydrogen cyanide gas or hydrogen sulfide gas sufficient to harm human health or the environment.
Oxidizer and organic peroxide test: it was determined whether the sample had an oxidizing agent or an organic peroxide containing a peroxy group which is extremely liable to cause combustion or explosion.
