Abstract

The invention relates to a method for resource utilization of solid waste, comprising the following steps: S1 mixing water and a compound coupling agent, ultrasonically dispersing to obtain a compound coupling agent solution; S2 mixing solid waste with diatomite, Stir under magnetic force to obtain a solid waste-diatomite mixture; S3 mix the solid waste-diatomite mixture obtained in S2 with the complex coupling agent solution obtained in S1, and magnetically stir for 2h to 4h to obtain a filler. The invention realizes the resource utilization of solid waste, reduces the production cost of enterprises, avoids the secondary pollution of the environment by solid waste, and meets the current industrial development requirements of energy saving, environmental protection, and circular green economy.

Description

technical field [0001] The invention relates to the field of recycling of solid waste resources, in particular to a method for resource utilization of solid waste. Background technique [0002] Industrial solid waste, short for industrial solid waste, refers to solid waste generated in industrial production activities, such as tailings generated by mining enterprises, including general industrial solid waste and hazardous waste. Hazardous waste refers to solid waste with hazardous characteristics that is included in the national list of hazardous waste or identified according to the national hazardous waste identification standards and identification methods. [0003] Industrial solid waste originates in the process of industrial production and operation, and the composition of industrial solid waste produced by each industry is relatively simple, but there are many types. The pollution characteristics are as follows: (1) Industrial solid waste pollution is difficult to tran...
