NOVELTY - Combustion of medicinal waste by high thermal pyrolysis and eliminating secondary pollutants comprises feeding the waste, crushing, igniting, which generates small amount of pyrolysis gas to enhance the pyrolysis rate, feeding air, generation of carbon dioxide with red hot carbon layer produced by the reaction of water gas, combusting the fuel gas, performing heat transfer from the combustion chamber of the pyrolysis chamber to optimize pyrolysis rate and waste incineration process, processing secondary pollutants comprising tail gas and sulfhydryl containing components and harmful components.    USE - The method is useful for pyrolysis of organic components after sieving domestic waste.    ADVANTAGE - The method: adopts biochemical treatment for processing and recycling waste; utilizes domestic sewage, which does not consume fresh water; purifies and recycles sewage; reduces tail gas temperature and dust; comprises tail gas desulfurization which adopts biological desulfurization process by using microbial metabolism of alkaline substances and sulfur dioxide in the tail gas, and does not require soda lime or other chemical substances, thus the method does not generate secondary pollution; recycles the nutrient solution which is replenished periodically; does not cause adverse effect; improves pyrolysis rate; and saves energy and is ecofriendly.    DETAILED DESCRIPTION - Combustion of medicinal waste by high thermal pyrolysis and eliminating secondary pollutants comprises (a) directly feeding the medicinal waste without opening the primary package, crushing in a pyrolysis chamber via a hydraulic transmission device, (b) igniting, where the ignition process consumes small amount of coal or wood in the pyrolysis chamber, which generates small amount of pyrolysis gas to enhance the pyrolysis rate of the medicinal waste until the treatment load is reached, where the treatment process is continuous and stable, feeding air to the waste and generation of water vapor from the water in the waste, generation of carbon dioxide with red hot carbon layer produced by the reaction of water gas to achieve a net capacity of pyrolysis of medicinal waste, (c) performing combustion of the fuel gas, performing heat transfer from the combustion chamber of the pyrolysis chamber for maximum pyrolysis rate and water gas generation to optimize pyrolysis rate and waste incineration process, and (d) processing the secondary pollutants of the medicinal waste, where two types of secondary pollutants are generated, which is cooling tail gas generated by acidic waste water and sulfhydryl containing components and harmful components generated by incineration.
