1. Both wastes are hazardous wastes, but there are obvious differences in hazardous characteristics, medical waste is mainly infectious, need to avoid human contact and airborne virus transmission. Industrial waste is more complex, with flammability, corrosivity, toxicity, reactivity and other different hazardous characteristics. The two types of waste disposal measures and incineration flue gas pollution prevention measures are not the same.
2. Industrial waste incineration treatment more rotary kiln, easy to feed the material ratio operation. Medical waste to avoid human contact and airborne, need to enter the furnace directly, the two types of waste feeding methods are very different. If the operation is not appropriate, there will be a foreign infection of medical waste.
3. There are differences in the tail gas treatment process, the focus of medical waste tail gas treatment and the difficulty is the pollution prevention and control of dioxin, and for other emission indicators, incineration process is stable, flue gas treatment process can be mature enough to meet the high expectations. As for industrial waste, due to its complex content, it needs to be strengthened in many aspects, such as sulfur-containing compounds, nitrogen oxides, heavy metals, dioxins and other indicators, which need to have corresponding prevention and control measures. The cost of mixing the two types of waste to burn medical waste will increase.
4. Medical waste contains a lot of medicine, blood and glass products, etc., the incoming material content is not controllable, but according to the regulations and must be processed within 24 hours, such as rotary kiln furnace for incineration, you need to take targeted measures such as pre-treatment, otherwise it will seriously affect the furnace refractory life, or lead to the occurrence of poor material and so on.
In short, in the process of industrial waste incineration, mixed burning of medical waste is a last resort, a small amount, short-term acceptable, if you need to deal with more than 10-15 tons / day of medical waste, it is recommended that should be increased facilities, separate treatment, otherwise it will affect production. Industrial waste can be temporarily stored waiting for processing, but medical waste must be completed within a short period of time to dispose of, if the incineration facility production is not normal, there will be a greater environmental safety hazards, serious problems.
