Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] A method for resourceful treatment of incineration slag, comprising the following steps in the process of vitrifying the incineration slag: uniformly mixing the incineration slag with waste glass slag, wherein the amount of waste glass slag added is 1% of the weight of the incineration slag- 7%, preferably 5% in the present invention. Fluid is formed after combustion under the conditions of negative pressure of 0-20Pa, load of 2.3T / h and temperature of 1050-1150°C, wherein the burning time is 1.5h...

Abstract

The invention relates to the technical field of hazardous waste treatment, and discloses a resourceful treatment method of incineration slag, in the process of vitrification treatment of the incineration slag, the method comprises the following steps: uniformly mixing the incineration slag with the incineration slag, burning at 1050-1150 DEG C to form a fluid, and cooling the fluid to obtain a glass body. By adopting the method, the temperature for forming the glass body can be reduced, and the production cost is reduced; and the contents of heavy metals and leachable harmful substances in the glass body are low, so that resource reutilization can be realized.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a resource treatment method for incineration slag. Background technique [0002] With the rapid development of the economy, urban waste is also increasing, and with the increasing shortage of urban land resources, the waste incineration technology with the advantages of high volume reduction, high volume reduction, high temperature disinfection, and heat energy utilization is harmless to domestic waste. The application proportion in chemical treatment is getting higher and higher. [0003] Household waste is incinerated at the disposal site, and most of the incinerator slag is directly landfilled after the heavy metal content of the incineration slag is tested by the laboratory. Although the heavy metal content fully complies with the GB18598-2019 hazardous waste landfill pollution control standard, if the resources of hazardous waste are realized In order to a...
