Embodiment 1

[0032] A green hospital sewage integrated treatment process, hospital sewage sequentially passes through septic tank, grid mesh, regulating tank, biological pool, ultra-magnetic separation system and mud-water separation system;

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

[0034] A certain amount of ABS microbial agent is added to the biological pool. When the sewage is full of the biological pool, aeration is started, and a certain amount of aeration is controlled to completely degrade t...

Embodiment 2

[0038] This embodiment provides a kind of ABS microbial bacterial agent, comprises saprophytic Ascomycetes, Aureobasidiomycetes, Acetobacter malate, Bacillus subtilis, Bacillus licheniformis, Paenibacillus polymyxa, Clostridia longum, Bifidobacterium longum Bacillus, Bifidobacterium breve, Nitrifying bacteria, Denitrifying bacteria, Streptocystis and Streptomyces sp.

[0039] The strain source and function of each microorganism provided in this embodiment:

[0040] Saprophytic Ascomycetes, whose Latin name is Saprophytic Ascomycetes, was purchased from Beijing Biobowell Biotechnology Co., Ltd., and the product number is bio-089576.

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

[0042] Ascomycetes saprophyta and Aureobasidiomycota play an important role in the ecosystem and the cycle of organic matter. They a...

Embodiment 3

[0096] This embodiment provides a method for activating the ABS microbial agent prepared in Example 2 in a septic tank or a collection tank or a biological pool:

[0097] Put the first ABS microbial agent into the septic tank or collection tank or biological pool evenly at one time, and 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 rate 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 and proliferating, COD120 and Escherichia coli below 1100 were detected in the water. Monitor and adjust the system to run. 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 belongs to the technical field of wastewater treatment, relates to a process for green integrated treatment of hospital wastewater and aims to solve the problem of incompleteness in pathogenic microorganism and organic matter clearing in application of an existing hospital wastewater treatment method. The process includes that the hospital wastewater sequentially flows through a septic tank, a grating net, a regulating tank, a biological tank, a super-magnetic separation system and a mud-water separation system; ABS microbial agents are added into both the septic tank and the biological tank, and primary degradation and complete degradation of pollutants such as COD, BOD, SS, escherichia coli and TN are sequentially performed; wastewater treated by the biological tank entersthe super-magnetic separation system to remove insoluble pollutants. By effective combination of an ABS microbial agent treatment method and a super-magnetic separation water treatment method, the environmental problem that hospital wastewater treatment does not reach standards is solved, adoption of chemical agents for disinfection is avoided, and accordingly wastewater treatment cost is saved, secondary pollution is avoided, up-to-standard discharge is realized, and reclaimed water recycling can be realized.

Description

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