Description
Technical Field
The invention belongs to the field of environment-friendly treatment of infectious disease waste liquid, and particularly relates to an emergency disinfection and continuous treatment device and method for the infectious disease waste liquid, which are a device and a method for treating and preventing infection and deeply degrading antibiotics in acute infectious disease high-incidence medical waste liquid such as coronavirus and African swine fever, and can be applied to hospitals, shelter, emergency mobile wards, breeding plants, poultry houses, excrement waste liquid and other places or mobile wards which can cause secondary infection.
Background
For large-scale infectious diseases, severe prevention and control can be implemented according to the basic epidemic prevention principle of 'controlling the infection source, cutting off the infection path and isolating susceptible people'. The problems of new pollution sources also exist in the process of collecting and treating medical waste liquid, discharging sewage and the like of hospitals and temporary rescue medical sites at various fixed points. The establishment of reasonable treatment methods for medical waste liquid, hospital fecal sewage equipment, medicaments and the like is more important for preventing pollution diffusion and inhibiting virus spread. The sewage treatment engineering generally adopts a pre-disinfection contact tank-septic tank-lifting pump station-regulating tank-MBBR biochemical tank-coagulating sedimentation tank-baffling disinfection tank-standard discharge mode, is mainly realized by building facilities with large occupied space, has long contact time, and is difficult to quickly realize certain existing fixed-point hospitals and temporarily built medical places.
In the prior fixed-point receiving and treating hospitals, virus treatment in sewage is mainly realized by physical and chemical disinfection and biological purification, and the main processes are that a septic tank is in contact oxidation and is discharged into an urban sewage pipe network after being disinfected by a chlorine-containing disinfectant. Wherein the dosage of the preoxidation concentration effective chlorine is about 10mg/L, the effective chlorine contacting the disinfection tank is about 50mg/L, and the residual chlorine of effluent is required not to exceed 5 mg/L. Many fixed-point collection and treatment hospitals are optimized on the basis of the original technology, and the sewage treatment process adopts a pre-disinfection contact tank, a septic tank, a lifting pump station, an adjusting tank, an MBBR biochemical tank, a coagulating sedimentation tank, a baffling disinfection tank and standard discharge; the waste gas treatment process adopts activated carbon and ultraviolet catalysis, namely, a biochemical treatment technology is adopted in addition to the conventional physical technology, so that various bacteria and viruses can be effectively eliminated. The fixed building facilities have larger occupied space and long contact time, the disinfection residence time of the fixed building facilities is as long as 5 hours, which is far higher than 1.5 hours of common medical wastewater, but the method is difficult to realize quickly for some existing hospitals and temporary medical places.
Meanwhile, the influence of the connection of the virus and the particulate matter on disinfection and sterilization is analyzed according to the state of the related virus in the sewage. Viral aggregates or fibrous (fibers) and cluster (cluster) structures are first present in the host cell; secondly, the cells accumulate between the host cells and the cellular debris that is generated as a result of the destruction of the host cells; self-aggregation also occurs when the virus is close to the isoelectric point of the virus due to changes in the pH of the solution and the concentration of salts; may exist between cells or exist at the gas-water interface after being induced by polyelectrolyte or forming polymerization with organic and inorganic particles in water; the fifth case is where the virus is present on a solid dry surface after being subjected to uv sterilization and repeated freezing. The formation of the above 5 kinds of aggregates may also be affected by temperature and electrostatic force, hydrophobic force. The aggregation of such viruses is not necessarily advantageous or disadvantageous for sterilization, and at present, the sterilization is mainly performed in consideration of the CT value, but the present invention is mainly performed in consideration of the existence state of the viruses, and the introduction of the state parameter F, that is, the sterilization effect, is in consideration of the CTF value, and a combined treatment method and apparatus are established in consideration of how the actual state reduces the influence of F and the process of aerogel formation and solid formation during the treatment, and the respective deep sterilization treatments are performed.
Meanwhile, in the process of designing and preparing the device, in order to adapt to the treatment of the waste liquid and the sewage of the similar mobile medical treatment points, the flexible and reliable movable purification treatment device and the method are developed, so that the treatment burden of the medical waste liquid and the sewage of the fixed-point hospital which is imposed at present can be relieved, and the device has important use value for the waste liquid treatment of the newly-built shelter hospitals at various places and the temporary wards built at various places in the future.
