In view of the novel coronavirus infection situation in the infectious hospital and the prevention of the spread and spread of the virus through the sewage, we refer to the technical guidelines for hospital sewage treatment (2003 [197]) and the technical specification for hospital sewage treatment (HJ). 2029-2013) and the novel coronavirus pollution emergency treatment technology plan for medical sewage (Trial Implementation), etc., based on the original integrated equipment, the pre disinfection module is added to further strengthen the disinfection of medical wastewater, and the final disinfection is carried out to ensure that the sewage reaches the discharge standard. It is not only suitable for the treatment of wastewater from general hospitals, specialized hospitals, health clinics, rural health stations, etc., but also for the outbreak of infectious diseases under special circumstances, it can ensure that the quality of effluent reaches the standard (Pic 1-1).

The process flow of the system is shown in Figure 1-2. After being treated by the pre disinfection module, the wastewater enters the MBBR integrated equipment through the regulating tank, which can give full play to the advantages of MBBR, such as its strong impact resistance, synchronous strengthening of nitrogen and phosphorus removal, etc., and ensure that the conventional indicators such as cod and ammonia nitrogen of the effluent can reach the standard stably. On the other hand, through the pre disinfection module and the back-end strengthening of disinfection, the integrated sterilization and disinfection effect can be enhanced to ensure that the effluent can meet the requirements of "medical treatment" The requirements of "discharge limits of water pollutants for medical institutions of infectious diseases and tuberculosis" in the discharge standard of water pollutants for medical institutions (Table 1-1).
