Abstract

The invention belongs to the technical field of waste incineration and particularly discloses a pretreatment combination method of hazardous waste. The pretreatment combination method includes the steps of firstly, performing solid, liquid and semi-solid classification on the waste, and placing the classified waste into a storage; secondly, performing property detection on the hazardous waste which needs to be incinerated to determine the heat value, volatile component, halogen content, heavy metal content, combustibility, liquid viscosity and chemical reactivity; thirdly, performing compatibility analysis which includes theoretical analysis and experimental analysis on the waste of the storage; fourthly, performing combination calculation according to the heat value, volatile component, halogen content and heavy metal content, and guaranteeing heat value stability; fifthly, determining the combination quantity of different waste according to the calculation results in the fourth step,and mixing. The method has the advantages that the method is mainly used for hazardous waste combination, and the problem that potential safety hazards are easily caused by the incineration of different kinds of hazardous waste is solved.

Description

technical field [0001] The invention belongs to the technical field of waste incineration, and specifically discloses a pretreatment compatibility method for hazardous waste. Background technique [0002] In densely populated cities, hospitals or factories will generate more hazardous waste, and the disposal of hazardous waste is a headache. Common way is to send to landfill after collecting for landfill treatment, or burn with incinerator. But both will cause environmental protection problems. The disposal of hazardous waste in landfills will not only pollute the groundwater and emit bad smells, but also the area available for landfills in many cities has become less and less. Incineration of hazardous waste can effectively reduce the landfill area and solve the problem of land shortage; waste heat can also be used for power generation and heating through incineration of waste. [0003] In the process of incinerating hazardous waste, it is necessary to mix different types...
