A multi-stage treatment method and device for biomedical wastes and a recycling method of the treated wastes. The multi-stage treatment method comprises the following steps: (1) carrying out the first stage of disinfection treatment on biomedical wastes using a hyperoxide disinfectant with concentration of 0.1-0.5% while comminuting the biomedical wastes; (2) carrying out the second stage of disinfection treatment on the biomedical wastes having residual hyperoxide disinfectant after the first stage of disinfection treatment, wherein the second stage of disinfection treatment refers to steam sterilizing heat treatment or disinfection using a high-concentration hyperoxide disinfectant with concentration of 5-20%. The method has the advantages of good sterilizing effect and short sterilizing time; the recycled product can be applied to decoration, isolation, building materials, containers and can be used as an alternative of cement.
A: An industrial solid waste treatment apparatus, comprising a baseplate (1), a feeding device (2), a first treatment structure (3), a first recovery device (4), a lifting device (5), a second treatment structure (6), a drying device (7), a holder device (8) and a second recovery device (9). With the industrial solid waste treatment apparatus, industrial solid waste can be crushed. The crushed waste is treated with some disinfectants or treating fluids so as to prevent the propagation of harmful substances thereon and protect the environment. Materials such as iron in the waste can also be reacted with sulphuric acid so as to facilitate the recovery thereof and reduce wasting of resources.
B: The present invention relates to the technical field of disinfectants for livestock and poultry, and disclosed thereby is a compound hydrogen peroxide disinfection diluent. The diluent is a solution containing 10-20 wt% of a compound hydrogen peroxide disinfectant. The compound hydrogen peroxide disinfectant is prepared from the following components in weight percentage: 21-25.5% of hydrogen peroxide, 9.9-19.8% of acetic acid, 0.3-1% of etidronic acid, and 0.1-1.5% of dodecyl dimethyl benzyl ammonium chloride and/or dodecyl dimethyl benzyl ammonium bromide, the rest being water. The diluent has strong disinfecting capabilities, is harmless to the human body and the environment, and achieves the effect of quick cleaning and disinfection in a general operation environment, while guaranteeing that the disinfectant is less harmful to the human body and the environment. Meanwhile, further provided by the present invention is a special use of the described diluent and a method for disinfecting the surface of an egg by employing the described diluent.
C: Provided are a chitosan derivative-based disinfectant and a preparation method therefor. The disinfectant comprises 0.05 to 10 g of chitosan derivative and 100 ml of sterilized deionized water. The disinfectant can be used as a bactericidal disinfectant in medical treatment and can be used for disinfection of skin or mucous membranes and the like.
D: Disclosed in the present invention are an apparatus and method for using biomedical waste. The method comprises two stages of chemical disinfection of the biomedical waste, and cyclic utilization of solids and liquids. Also disclosed are novel processes for preparation and recycling of a disinfectant which is rich in free radicals and recyclable, thereby achieving zero liquid discharge. Also disclosed are a method, process, and apparatus for thermally decomposing solid waste into fuel under an air-free condition. Thus, solid discharge is zero, air pollution is minimized, and carbon emissions are low.
