Potassium monopersulfate composite disinfectant for hospital sewage treatment

Abstract

The invention specifically relates to a potassium monopersulfate compound disinfectant for treatment of hospital sewage, belonging to the field of disinfectants. The compound disinfectant is prepared from the following raw materials by mass: 50-60% of potassium monopersulfate, 2-3% of sodium chloride, 10-15% of malic acid, 0-20% of citric acid, 0-30% of sodium cyanurate and 0-10% of sodium silicate. A preparation method for the compound disinfectant comprises the following steps: dissolving the above raw materials in water according to a mass concentration ratio of 20-30 g / L and carrying out irradiation by using an ultraviolet lamp with a wavelength of 240-280 nm and radiation Intensity of 90 [mu]W / cm<2> for 5 min so as to obtain the compound disinfectant. The compound disinfectant of the invention has the advantages of scientific combination of the components, simple production process flow, low production cost, safety, stability, easiness in application, and rapid, broad-spectrum and long-lasting sterilization and disinfection, and is applicable to the complicated working condition of hospital sewage, high in efficiency and safety, free of pollution and low in comprehensive cost.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a potassium monopersulfate compound disinfectant for hospital sewage treatment. Background technique [0002] At present, the treatment of sewage produced in hospitals still mostly uses disinfectants based on available chlorine for disinfection, but chlorine-containing disinfectants will produce many by-products in the process of use, such as chlorinated hydrocarbons, chloroacetic acid, Chloroacetonitrile, ketone, etc., and epidemiological investigations have shown that these by-products are closely related to urinary system cancer, gastrointestinal cancer, abortion in pregnant women, and other reproductive and developmental problems, such as carbon dioxide, which is the main component of some disinfectants. Chlorine, although its animal experiments are of non-toxic grade, but the high concentration of chlorine dioxide and its by-products may be potentially harmful to human health, the standardi...

[0006] (3) Although the disinfection effect of peroxygen disinfectant is better than that of chlorine gas and chlorine dioxide, its safety evaluation still needs further research

[0007] CN104719336A discloses a low-corrosivity potassium monopersulfate compound salt disinfectant. The main component of the disinfectant of the formula that plays a role in disinfection and sterilization is potassium monopersulfate. Due to the characteristics of potassium monopersulfate itself, the formula More auxiliary ingredients are needed to achieve the purpose of effective sterilization, which also causes the problem of complex ingredients and high cost
