Problems solved by technology

The cost of the existing activated sludge sewage treatment process is high, and the COD (chemical oxygen demand, Chemical Oxygen Demand) removal rate is not ideal
[0004] In recent years, microbial preparations have been used in water environment improvement, but there are many problems, such as some microorganisms cannot produce enzymes, but simply absorb small molecule nutrients in water bodies, and cannot effectively promote the material circulation of water body environments. slower

Embodiment 1

[0028] In the embodiment of the present invention, aquaculture sewage is treated.

[0029] 1. Implementation location: a farm in Beijing, Hubei.

[0030] 2. Water treatment capacity: the average treated sewage is 100d / T, and the treated water is livestock manure, which contains high organic matter.

[0031] 3. Use method and process: use composite bacterial agent technology to treat sewage.

[0032] The specific treatment process is as follows: After the sewage is fermented in the anaerobic tank, it enters the aerobic tank through the pipeline, and is aerated in the aerobic tank to increase the dissolved oxygen in the sewage to make the dissolved oxygen reach more than 2ppm. Add artificial biological filler in the aerobic tank, when the sewage passes through the biofilm formed by a large amount of composite bacteria, the nutrients in the water body are fully absorbed by the composite bacteria on the biofilm, and then the treated water is filtered twice pool outflow.

Embodiment 2

[0039] In the embodiment of the present invention, urban domestic sewage treatment

[0040] 1. Implementation location: a sewage treatment plant in Jiangxia.

[0041] 2. Water treatment capacity: the average treated sewage is 200d / T. The treated water is urban domestic sewage with high organic matter content.

[0042] 3. Use method and process: use composite bacterial agent technology to treat sewage.

[0043] The specific treatment process is as follows: After the sewage is fermented in the anaerobic tank, it enters the aerobic tank through the pipeline, and is aerated in the aerobic tank to increase the dissolved oxygen in the sewage to make the dissolved oxygen reach more than 2ppm. Add artificial biological filler in the aerobic tank, when the sewage passes through the biofilm formed by a large amount of composite bacteria, the nutrients in the water body are fully absorbed by the composite bacteria on the biofilm, and then the treated water flows out through the filter ...

Embodiment 3

[0050] In the embodiment of the present invention, a certain food factory sewage treatment

[0051] 1. Implementation location: sewage treatment plant of a food company in Wuhan.

[0052] 2. Water treatment capacity: the average treated sewage is 400d / T. The treated water is livestock manure, which contains high organic matter.

[0053] 3. Use method and process: use composite bacterial agent technology to treat sewage.

[0054] The specific treatment process is as follows: After the sewage is fermented in the anaerobic tank, it enters the aerobic tank through the pipeline, and is aerated in the aerobic tank to increase the dissolved oxygen in the sewage to make the dissolved oxygen reach more than 2ppm. Add artificial biological filler in the aerobic tank, when the sewage passes through the biofilm formed by a large amount of composite bacteria, the nutrients in the water body are fully absorbed by the composite bacteria on the biofilm, and then the treated water flows out ...

Abstract

The invention discloses a compound microbial inoculant for degrading chemical oxygen demand and a preparation method of the compound microbial inoculant. The compound microbial inoculant comprises, by volume, 9-11% of candida tropicalis, 9-11% of candida parapsilosis, 28-32% of bacillus subtilis, 28-32% of bacillus licheniformis and 19-21% of enterococcus faecalis lactobacillus. The preparation method of the compound microbial inoculant includes that the candida tropicalis, the candida parapsilosis, the bacillus subtilis, the bacillus licheniformis and the enterococcus faecalis lactobacillus are respectively inoculated and cultured in sewage culturing media to obtain respective bacterium solutions, and the bacterium solutions are mixed according to the volume ratio to obtain the compound microbial inoculant, wherein the sewage culturing media are abundant in organic matter after being sterilized. The compound microbial inoculant is high in environment adaptability, applicable to microbial enhanced sewage treatment in different areas and various sewage including aquaculture sewage, domestic sewage, landfill leachate and the like which are abundant in organic matter, and capable of removing 95% of the COD in sewage.

Description

technical field [0001] The invention relates to the field of microbial bacterial agents, in particular to a composite bacterial agent for degrading COD and a preparation method thereof. Background technique [0002] As we all know, mankind is currently facing various crises, such as food crisis, energy shortage, resource shortage, ecological deterioration and population explosion. After entering the 21st century, human beings will encounter a series of new problems arising from the transition from the era of utilizing limited mineral resources to the era of utilizing unlimited biological resources. Because microbial cells are a life system with a large specific value, strong biochemical transformation ability, and rapid self-replication, and they also have diversity in species, genetics, metabolism, and ecology, they can solve various crises faced by human beings. play an irreplaceable and unique role in it. [0003] Industrial pollution sources: Industrial wastewater is a...
