Embodiment 1

[0022] The preparation of embodiment 1 fermented liquid

[0023] This embodiment only takes Lactobacillus casei (ACCC10640), Candida tropicalis (ATCC7394) and Bacillus licheniformis (CGMCC1.3448) as examples to describe the specific content of the invention in detail, and does not limit the present invention. Choice of three microbial sources.

[0024] (1) Activate the above Lactobacillus casei (ACCC10640), Candida tropicalis (ATCC7394) and Bacillus licheniformis (CGMCC1.3448) into their respective slant media for preservation, and culture them at 26-37°C for 16-72 hours.

[0025] Preservation of three kinds of microorganisms uses the slant culture medium formula as follows:

[0026] Lactobacillus casei medium: 10.0 grams of casein peptone, 10.0 grams of beef extract, 5.0 grams of yeast extract, 5.0 grams of glucose, 5.0 grams of sodium acetate, 2.0 grams of diammonium citrate, 1.0 grams of Tween80, K 2 HPO 4 2.0 g, M g SO 4 ·7H 2 O0.02 g, MnSO 4 ·H 2 O 0.05 g, CaCO 3 ...

Embodiment 2

[0034] 1, three kinds of microbial fermented liquids prepared in embodiment 1 are mixed uniformly by following weight parts and become composite microbial inoculum: 15 parts by weight of Lactobacillus casei fermented liquid, 5 parts by weight of Candida tropicalis fermented liquid, 7 parts by weight of Bacillus licheniformis fermented liquid parts by weight;

[0035] 2. Select the effluent from the anaerobic section of a food processing plant (fruit) sewage treatment plant (COD is 750mg / L, pH7.4), and add it to 4 contact oxidation reactors with an effective volume of 5L;

[0036]3. Add 3 mL of the following microbial fermentation liquid or microbial fermentation liquid mixture to the four contact oxidation reactors: a: Lactobacillus casei fermentation liquid, b: Lactobacillus casei fermentation liquid and Candida tropicalis fermentation liquid, c: Composite microbial agent prepared in step 1, d: blank control, add 100mL of aerobic sludge (solid content 5%). Mix evenly, keep t...

Embodiment 3

[0042] 1, three kinds of microorganisms in embodiment 1 are replaced with following source: Lactobacillus casei (CICC20363), Candida tropicalis (ATCC20326), Bacillus licheniformis (CICC10087); Prepare three kinds of microorganism fermentations according to the method for embodiment 1 Liquid, mixed uniformly according to the following parts by weight to become a composite microbial bacterial agent I: 10 parts by weight of Lactobacillus casei fermentation liquid, 8 parts by weight of Candida tropicalis fermentation liquid, 10 parts by weight of Bacillus licheniformis fermentation liquid; mix uniformly according to the following parts by weight To become a composite microbial bacterial agent II: 6 parts by weight of Lactobacillus casei fermentation liquid, 15 parts by weight of Candida tropicalis fermentation liquid, and 20 parts by weight of Bacillus licheniformis fermentation liquid.

[0043] 2. Select the effluent from the anaerobic section of the sewage treatment plant of a fo...

Abstract

The invention belongs to the field of biological environmental protection, and discloses a compound microbial agent for aerobic treatment on food processing wastewater and an application of the compound microbial agent. The compound microbial agent is composed of fermentation broth of lactobacillus casei, candida tropicalis and bacillus licheniformis. With the compound microbial agent, various organic matters causing increase of COD and BOD of food wastewater can be effectively degraded and removed under the aerobic condition. When added for the debugging purpose in the aerobic treatment technology of food wastewater, the microbial agent can accelerate enrichment of microbes during aerobic treatment, and shorten the debugging time; when added for the enhancing purpose in the aerobic treatment technology of food wastewater, the effluent quality of the aerobic treatment technology can be improved; and the synergy of the three microbial strains is better than the effect of any one or two microbial strains.

Description

technical field [0001] The invention belongs to the field of biological environmental protection, and relates to a compound microbial bacterial agent for aerobically treating food processing wastewater and an application thereof. Background technique [0002] Raw materials for food processing include meat, aquatic products, fruits, vegetables, sugar, etc. The wide range of raw materials and various types of products lead to great differences in the amount and quality of discharged wastewater, high content of organic matter and suspended solids, and oil in some wastewater If the content is large, BOD and COD will be as high as thousands or even over ten thousand. Generally, it does not contain harmful substances such as heavy metals and pesticides, and has good biochemical properties. If the wastewater is not treated in time, it will cause great pollution to the environment. [0003] In the aerobic treatment process of food wastewater, activated sludge from other sewage treat...
