Abstract

The invention provides a biological waste harmless treatment device and method, belonging to the technical field of biological waste treatment. In the present invention, the biological activity in the material is reduced by freezing the refrigeration component, and it can also prevent the material from escaping when crushed, and it can also make the material more brittle and hard, so that it can be completely crushed, and the soft material can be prevented from being entangled on the crushing component. After crushing, the material can react quickly and fully with the sprayed lye, which can more fully kill microorganisms such as bacteria and viruses, and decompose biological toxins, and then neutralize by adding acid, which can prevent the material from Excessive medium alkalinity can cause danger, and it can also react with alkaline toxins in materials, and react with lye to generate heat, kill cold-resistant bacteria, spores, etc., and finally realize the harmlessness of materials; the device is simple to use, It is safe and convenient, and can quickly and one-stop harmlessly treat most of the biological waste, which is more conducive to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of biological waste treatment, and more specifically relates to a device and method for harmless treatment of biological waste. Background technique [0002] After biological experiments or biological detection, a lot of biological waste will be produced. Since some biological waste may contain dangerous factors such as toxins, infectious bacteria or viruses, special treatment is required, and the treatment of biological waste generally has treatment requirements High, professional, and troublesome to deal with, there are different ways to deal with different biological wastes. The commonly used treatment methods are immersion disinfection, autoclave sterilization or incineration, etc. The methods of immersion disinfection and autoclave sterilization can only kill one type of risk factors. For biological wastes with unknown pollution sources, mixed biological wastes or accidental Mixed biological waste ofte...
