Problems solved by technology

This method is better than the first two methods, but the process is cumbersome, and the fermentation time is as long as 60 days. It is necessary to build multiple large-scale fermentation tanks with ventilation and exhaust equipment, and to collect naturally active microorganisms and mold microorganisms, which takes a lot of labor and effort. Money, time is also very long

Embodiment 1

[0036] 1. The microbial starter for treating alcohol waste liquid is a microbial flora, all of which are composed of Bacillus polymyxa CGMCC 0395.1, named WH1 strain; Bacillus subtilis CGMCC 0395.2, named WH2 strain; Bacillus brevis CGMCC0395.3, named WH3 strain; Bacillus licheniformis CGMCC 0395.4, called WH4 strain; Brevibacterium thiochrome CGMCC 0395.5, named WH5 strain and so on to form the WH flora.

[0037] The proportioning of above-mentioned microbial flora is (percentage by weight):

[0038] WH1 strains: 20 WH2 strains: 20

[0039] WH3 strains: 22 WH4 strains: 12

[0040] WH5 strains: 26.

[0041] 2. Preparation method of microbial preparation-alcohol waste liquid starter:

[0042] (1) Prepare WH flora, mix WH1 strains, WH2 strains, WH3 strains, WH4 strains, and WH5 strains according to the above formula to form WH flora;

[0043] (2) The culture medium of the secondary strain is mixed and prepared according to the following formula (percentage by weight):

[00...

Embodiment 2

[0054] 1. The microbial fermentation agent for processing alcohol waste liquid is the same as in Example 1, but the proportioning of the microbial flora WH bacterial classification is (percentage by weight):

[0055] WH1 strains: 28 WH2 strains: 12

[0056] WH3 strains: 30 WH4 strains: 8

[0057] WH5 strains: 22.

[0058] 2. The preparation method of alcohol waste liquid starter:

[0059] (1) The preparation of WH flora is the same as in Example 1.

[0060] (2) The culture medium for secondary strain cultivation is the same as that of Example 1.

[0061] Inoculate the prepared secondary strain culture medium at room temperature with the above-mentioned WH flora. Two days later, white hyphae appear in the culture medium. The culture temperature rises to 38°C, the pH value is 6.9, and the heat is naturally dissipated. Turn it over after hardening, and the culture time is 9 The second-level active Pityriasis of WH flora was obtained in days.

[0062] (3) The culture medium f...

Embodiment 3

[0067] 1, the microbial strain embodiment one of processing alcohol waste liquid is identical, but the proportioning of microbial flora WH bacterial classification is (percentage by weight):

[0068] WH1 strains: 35 WH2 strains: 5

[0069] WH3 strains: 15 WH4 strains: 15

[0070] WH5 strains: 30.

[0071] 2. The preparation method of alcohol waste liquid starter:

[0072] (1) The preparation of WH flora is the same as in Example 1.

[0073] (2) The culture medium for secondary strain cultivation is the same as that of Example 1.

[0074] Inoculate the prepared secondary culture medium with WH flora at room temperature. Two days later, white hyphae appear in the medium. The culture temperature rises to 40°C, the pH value is 6.8, natural heat dissipation, and the culture time is 8 days. Obtain secondary active Pityrosporum of WH flora.

[0075] (3) The culture medium for the three-stage strain cultivation is the same as that of Example 1.

Abstract

The present invention relates to a microbial fermentation agent for treating waste alcohol liquid of sugar refinery and alcohol plant and it is a kind of bacillus and named WH colony. It is used to treat waste alcohol liquid and waste alcohol liquid and filtered mud is used as the second-stage culture medium, third-stage culture medium and carrier for WH colony. The fermented filtered mud is usedas material for producing organic fertilizer. The present invention has low cost and short technological process, and makes it possible to solve the problem of environment protection while increasingbenefit.

Description

technical field [0001] The invention relates to the technical field of alcohol waste liquid treatment, in particular to a microbial fermentation agent for treating alcohol waste liquid and a preparation method thereof. Background technique [0002] At present, there are more than 400 cane sugar factories in my country, and the by-products of sugar production are used to produce alcohol through the alcohol workshop. 3 Alcohol needs to be discharged 20m 3 Alcohol waste liquid, with an annual output of 25,000 m 3 Alcohol, need to discharge 500,000 m 3 Wine clear waste. Alcohol waste liquid contains high concentrations of COD (chemical oxygen demand), BOD (biological oxygen demand) and SS (suspended solids), which are directly discharged to cause serious pollution to the local natural ecological environment. For a long time, a lot of money, manpower and material resources have been invested to deal with the problem of alcohol waste liquid, and there is no better treatment pl...
