Description

Temporary hospital is with infectious disease waste liquid purification unit

Technical Field

The invention belongs to the field of medical waste treatment, and particularly relates to a temporary infectious disease waste liquid purification treatment device for hospitals.

Background

Medical waste is waste of direct or indirect infectious, toxic and other hazardous nature generated by health care institutions in medical, preventive, healthcare and other related activities, and includes: the waste human pathological tissues in operation, waste generated in the surgical dressing process, disposable medical supplies, expired and abandoned medical drugs, etc., but the most harmful medical waste and the most contagious one is the operation waste liquid, which is the liquid waste generated in the operation process, such as blood, body fluid, etc., for the body tissues suffering from the infectious diseases per se, such as: patients with AIDS and hepatitis B often have high-concentration pathogens in the operation waste liquid generated in the operation process, have high infectivity, and not only doctors are easily scratched by an operating knife in the operation process to cause occupational exposure risk, but also the operation waste liquid directly rushes into a sewer to pollute a water source and then has the risk of pathogen diffusion when being discharged into a river; the interim hospital often does not have the perfect purification system as traditional hospital, moreover after the epidemic situation finishes, these interim hospitals all will demolish or resume original usage, if directly adopt traditional purifier, because the volume is great, be difficult to find the position of settling, it is also very troublesome to transport moreover, consequently needs a moderate and better waste liquid purifier of purifying effect of volume.

According to the known knowledge: chlorine dioxide is a broad-spectrum bactericide with excellent sterilizing effect, the performance of the broad-spectrum bactericide is better than that of the traditional chlorine and ozone, the chlorine dioxide is easy to dissolve in water and does not chemically react with the water, the solubility of the chlorine dioxide in the water is 5 times of that of chlorine, but the chlorine dioxide is easy to explode, the explosion can be caused by the temperature rise or the exposure to light, the chlorine dioxide needs to be diluted, and therefore high-temperature objects cannot be contacted to avoid the explosion, and a new technical challenge is also provided for the storage and the transportation of the chlorine dioxide.
