[0002] Hazardous laboratory waste mainly includes various waste chemical reagents that have expired and expired, as well as toxic and harmful wastewater, waste liquid or waste residue generated during the experiment. Among them, the packaging bottles of various chemicals are also hazardous waste in the laboratory. If hazardous waste is discharged randomly, it will pollute the water body and soil, and reduce the environmental function level of the region. If no measures are taken to control it, it will definitely cause serious harm to the global environment;
[0003] The existing laboratory hazardous waste treatment technologies mainly include safe landfill, wet leaching, pyrometallurgy, etc., but these processes are complex, occupy a large area, consume high energy consumption, have low levels of production automation, and are labor-intensive. Large, poor working environment, workers may inhale harmful substances during work, causing damage to workers' health, and when mixing liquid laboratory hazardous waste, the bottom of the tank cannot be cleaned by the existing agitator. Stirring will cause accumulation of solid impurities at the bottom of the tank

Embodiment 1
[0027] A method for collaborative disposal of laboratory hazardous waste, comprising the following steps:
[0028] S1. Classification of hazardous waste in the laboratory. According to the analysis of the laboratory, hazardous waste in the laboratory is divided into solid, liquid and paste laboratory hazardous waste according to the characteristics and components. Among them, the hazardous waste in the solid laboratory is sent to the solid laboratory respectively. Each storage tank in the hazardous waste storage area is stored in the solid laboratory hazardous waste crushing tank, the high calorific value solid laboratory hazardous waste storage tank and the low calorific value solid laboratory hazardous waste storage tank. The barreled laboratory waste liquid passes through the vacuum system and the pump The delivery system is transported to the waste liquid storage tank for storage. The pasty laboratory hazardous waste is filtered by the coarse filter and then transported to ...

The invention discloses a laboratory hazardous waste co-processing system and method, and belongs to the technical field of laboratory hazardous waste processing. The method comprises the following steps of classification, pretreatment and incineration of laboratory hazardous waste, and utilization of flue gas. The laboratory hazardous waste in different forms is classified and pretreated, so thatthe laboratory hazardous waste can be combusted more sufficiently in a rotary kiln; flue gas generated by incineration of the laboratory hazardous waste is subjected to secondary combustion, and harmful substances can be combusted sufficiently; workers are prevented from inhaling the harmful substances directly; the flue gas generated by secondary combustion is recycled, so that the resource utilization rate of the system is greatly improved; environmental hazardous substances are reduced, the resource utilization rate of the system is greatly improved, and the environmental risk is reduced.
