[0048]

[0049] Where β represents the risk factor correction value of public safety in hazardous waste resource utilization, M represents the public exposure to hazardous waste resource utilization, and K represents the leakage amount of hazardous waste resource utilization under abnormal conditions.

According to the risk ranking and priority, corresponding safety measures are formulated for different risk factors, such as adding protective facilities, improving treatment processes and increasing monitoring frequencies. The complete process flow of hazardous waste resource utilization is simulated, including waste reception, treatment, conversion, product purification and waste disposal. During the simulation process, the possible changes and interactions of various risk factors are considered. By simulating the process flow, the effectiveness of the safety measures that have been formulated under different working conditions is verified.
