A hospital sewage treatment process containing highly pathogenic virus

Abstract

The invention discloses a hospital sewage treatment process containing highly pathogenic viruses, relates to the technical field of sewage treatment, and specifically includes the following process steps: S1: Sewage is sequentially passed through a grid channel and a regulating pool, and the regulating pool is added with Bactericide, to obtain the pretreated sewage; S2: filter the pretreated sewage through the ultrafiltration membrane pool to obtain filtered water and concentrated sewage; S3: pass the filtered water into the hydrolytic acidification pool, aerobic pool, MBR in sequence The membrane tank is used for treatment, and after the treatment, the purified water that has been sterilized is obtained; the concentrated water is returned to the mixing place where the regulating tank and the grid canal enter the water for mixing, and the sterilizing treatment is continued through the regulating tank. The preparation method of the invention has the advantage of reducing the risk of secondary infection of highly pathogenic viruses.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a hospital sewage treatment process containing highly pathogenic viruses. Background technique [0002] Highly pathogenic viruses refer to viruses that can cause very serious or serious diseases in humans or animals, and are relatively easy to transmit directly or indirectly between humans, animals and humans, and animals. Among them, the new coronavirus at the end of 2019 is one of them. It has been confirmed as an acute respiratory infectious disease caused by the 2019 new coronavirus infection. Because the virus is highly contagious, the virus can also spread in the feces of infected people in addition to droplets. Survival in the environment, after the advanced treatment of hospital sewage by the traditional biochemical + MBR process, the effluent quality basically meets the first-class A standard, but in the process of biochemical and advanced treatment, gas or drop...

Among them, the new coronavirus at the end of 2019 is one of them. It has been confirmed as an acute respiratory infectious disease caused by the 2019 new coronavirus infection. Because the virus is highly contagious, the virus can also spread in the feces of infected people in addition to droplets. Survival in the environment, after the advanced treatment of hospital sewage by the traditional biochemical + MBR process, the effluent quality basically meets the first-class A standard, but in the process of biochemical and advanced treatment, gas or droplets will be generated, which will become highly pathogenic virus carriers, and then cause Practitioners have exposure risks through direct contact, droplet and aerosol inhalation, etc., and the residual sludge generated also has a greater risk of secondary infection in the post-processing process, which greatly endangers people's health.
