Embodiment 1

[0032] A green hospital sewage integrated treatment process, the hospital sewage passes through a septic tank, a grid net, a regulating tank, a biological tank, a supermagnetic separation system and a mud-water separation system in sequence;

[0033] A certain amount of ABS microbial inoculum is added into the septic tank or the collection tank, and after the sewage enters the septic tank, a certain amount of aeration is controlled to carry out primary degradation of the sewage, and after a certain period of treatment, the sewage is removed from the septic tank or the collection tank. After being discharged and filtered by the grid net, it enters the adjustment tank, and the sewage is discharged into the biological tank after the adjustment tank completes the pH adjustment;

[0034] A certain amount of ABS microbial inoculum is added to the biological pool. When the sewage is full of the biological pool, aeration starts, and a certain amount of aeration is controlled to complet...

Embodiment 2

[0038] This embodiment provides an ABS microbial inoculant, including saprophytic Ascomycetes, Aureobasidium pullulans, Acetobacter malate, Bacillus subtilis, Bacillus licheniformis, Paenibacillus polymyxa, Clostridium longum, Bifidobacterium longum Bacillus, Bifidobacterium breve, nitrifying bacteria, denitrifying bacteria, Streptomyces and Streptomyces.

[0039] The sources and functions of strains of each microorganism provided in this example:

[0040] The Latin name of Saprophytic Ascomycetes is Saprophytic Ascomycetes, which was purchased from Beijing Bio-Bow Biotechnology Co., Ltd., product number is bio-089576.

[0041] The Latin name of Aureobasidium pullulans var.melanigenum is Aureobasidium pullulans var.melanigenum, which was purchased from Beijing Bio-Broadway Biotechnology Co., Ltd., product number is bio-85564.

[0042] Saprophytic Ascomycetes and Aureus pullulans Basidiomycetes play an important role in ecosystems and organic material cycles, and are fungi tha...

Embodiment 3

[0096] The present embodiment provides a method for activating the ABS microbial inoculum prepared in Example 2 in a septic tank or a collection tank or a biological tank:

[0097] Put the ABS microbial inoculum into the septic tank or collection tank or biological tank evenly at one time, adjust the water intake in stages to reduce the impact on microorganisms, and open 1 / 3 of the normal water intake on the first day of operation , open 2 / 3 on the second day, fully open on the third day, then close the water inlet and outlet, keep the aeration state for 120h, the aeration volume is 45 ~ 50L / h per square meter, and the aeration time is 24h to activate the microorganisms and Adhering to biological media and / or fillers to proliferate, and detecting COD120 in water and Escherichia coli 1100 or less. Monitor and adjust the system operation, if the system is stable after about 8 days, there is no need to add ABS bacteria agent to complete the activation.

Abstract

The invention relates to an integrated treatment process for green hospital sewage, which belongs to the technical field of sewage treatment. In order to solve the problem of incomplete removal of pathogenic microorganisms and organic matter in existing hospital sewage treatment methods, the present invention provides a green integrated treatment process for hospital sewage. , ultra-magnetic separation system and mud-water separation system; both septic tanks and biological tanks are added with ABS microbial agents, and the pollutants such as COD, BOD, SS, E. coli and TN are degraded in turn; The treated sewage enters the ultra-magnetic separation system to remove insoluble pollutants. The invention effectively combines the ABS microbial agent treatment method with the supermagnetic separation water treatment method, which solves the environmental protection problem that hospital sewage treatment is not up to standard, does not need to use chemical agents for disinfection, saves sewage treatment costs, has no secondary pollution, and discharges up to the standard. Reclaimed water can be recycled.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a green hospital sewage integrated treatment process. Background technique [0002] Hospital sewage mainly comes from the sewage discharged from diagnosis and treatment rooms, wards, laboratories, operating rooms, laundry rooms, administrative departments, canteens, dormitories, etc. The main pollutants are organic pollutants, pathogenic microorganisms and viruses. an important factor in harming the environment. [0003] Pathogenic microorganisms have certain adaptability in the environment, and some can even survive in sewage for a long time, with the hazards of space pollution, acute infection and latent infection. If hospital sewage containing pathogenic microorganisms is discharged into urban sewers or environmental water without disinfection treatment, it will often cause water pollution, cause various diseases and infectious diseases, and seriously end...
