Problems solved by technology

These patents disclose the use of the above solutions at low concentrations for domestic, hospital and industrial use, but do not mention the use of such solutions for disinfection of medical waste
Moreover, the results of a 2015 study by Anhalt University of Applied Sciences showed that the combined use of hydrogen peroxide with glutaraldehyde and / or quaternary ammonium compounds has a synergistic disinfection effect, but will significantly affect the disinfection solution within 24 hours. Stability, which is mainly due to the reaction of hydrogen peroxide with other ingredients
[0008] Disinfection with a high concentration of sanitizer has never been patented because of the high cost and environmental impact of the sanitizer

Embodiment Construction

[0074] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0075] Specific examples are shown in the associated drawings. The size and function of the components shown in the figure are only for the accuracy and convenience of description, and are not actual scale.

[0076] Figure 1A It is a schematic structural diagram of the device of the present invention, including a reaction chamber 100 , a controller 110 and an enhanced sterilizer 108 . The reaction chamber 100 is used to treat waste to make it suitable for subsequent enhanced disinfection (steam sterilization heat treatment using an autoclave or high concentration peroxide disinfection solution disinfection with a hybrid reactor). The reaction chamber 100 is equipped with a drug dispenser 106, a shredder 104 and a reaction pool 102 for receiving biomedical waste or biol...

Abstract

The invention belongs to the field of biological / medical waste treatment, and discloses a multi-stage treatment method and equipment for biomedical wastes. The method comprises the following steps of (1) smashing the biomedical wastes, and meanwhile, adopting a peroxide disinfectant with the mass concentration being 0.1 to 0.5 percent for carrying out first-stage disinfection treatment on the biomedical wastes; (2) carrying out second-stage disinfection treatment on the treated wastes with the remained peroxide disinfectant and subjected to first-stage disinfection treatment, wherein the second-stage disinfection treatment is characterized by adopting steam sterilizing heat treatment or adopting a high-concentration peroxide disinfectant with the mass concentration being 5 percent to 20 percent for disinfecting. The equipment for implementing the method comprises the following devices: a reaction bin (including a dosage dispenser, a smasher and a disinfection reaction tank) for receiving the wastes, and an enhanced disinfector (including a high-pressure steam sterilizer or a mixed reactor); the multi-stage treatment method and the equipment for the biomedical wastes provided by the invention have the advantages of good sterilization effect, short time and better environmental protection effect.

Description

technical field [0001] The invention belongs to the field of biological / medical waste treatment, in particular to a multi-stage treatment method and equipment for biological medical waste. Background technique [0002] Biomedical waste (BMW) consists of solids, liquids, sharps and laboratory waste, which are potentially infectious and dangerous, such as containing bacteria, viruses and other microorganisms. Biomedical waste must be properly disposed of to protect public health, as well as groups such as medical and health workers who are frequently exposed to biomedical waste due to their work. [0003] In order to meet the disinfection standards of various microorganisms (including various bacteria, viruses, fungi and bacterial spores, etc.) required by laws and regulations, special equipment is required for the treatment process. In addition, in order to meet the legal requirements of treating biomedical waste in an "unidentifiable" state, and to expose the waste to heat ...
