Abstract

The invention discloses a rigid landfill pretreatment process for hazardous waste. The rigid landfill pretreatment process involves a ton bag lifting system, a bag breaking feeding system, a closed dust removal system, a mixing and stirring system, a ton bag packaging system, a weighing system and a PLC control system. According to the rigid landfill pretreatment process, hazardous waste packages which are unqualified in entry are broken and bagged again; similar compatible hazardous waste is bagged again after being mixed, so that the moisture content is reduced; during packaging, ton bags vibrate through a vibration platform, the hazardous waste in the bags is tamped, and the volume reduction effect is achieved.

Description

technical field [0001] The invention relates to a hazardous waste rigid landfill pretreatment process. Background technique [0002] Solid waste that is included in the National Hazardous Waste List or identified according to the national hazardous waste identification standards and identification methods with hazardous characteristics must meet the entry requirements of the landfill site before entering the site for landfill. Landfills are divided into flexible landfills and rigid landfills. According to the "Hazardous Waste Landfill Pollution Control Standard" (GB18598-2019), hazardous waste entering rigid landfills needs to be pretreated before being landfilled under certain circumstances, but there is no effective pretreatment equipment in the existing technology process. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a way to re-bag the unqualified hazardous waste packaging; for similar compatible ha...
