[0002] Hazardous waste refers to solid waste that is included in the national hazardous waste list or is identified as having hazardous characteristics according to the national hazardous waste identification standards and identification methods.

[0003] Safe landfill is a relatively mature treatment technology for hazardous waste. The existing rigid landfill adopts a single-layer structure, which leads to a large area of ​​rigid landfill and low land utilization rate. In addition, the existing rigid landfill is an integrated structure. When one part of the landfill is damaged, it will affect the normal operation of the entire landfill. In view of this, we propose a rigid landfill for hazardous waste. Utility Model Content
