In order to solve the problem of environmental pollution and resource waste caused by improper treatment of chemical solid waste,a study was conducted on the resource utilization of solid waste using melamine waste residue as an example.A pre-treatment plan and process were developed based on the characteristics of melamine waste residue.Design an experimental plan for the preparation of cyanuric acid from melamine.Experimental studies were conducted on the effects of reaction temperature,reaction time,and the amount of sodium bisulfate added on the yield of cyanuric acid by controlling variables.The research results can guide the resource utilization of melamine chemical solid waste.
