Problems solved by technology

After diatomite is used in beer production, a large amount of organic matter such as yeast, protein, and hop resin is adsorbed on its surface, and it becomes diatomite mud, and the filter-aid effect is reduced and can only be discarded. Or as solid waste landfill after sedimentation in the sedimentation tank, not only the waste of diatomaceous earth and water is caused, but also the untreated discharge will produce strong odor and cause serious environmental pollution

Embodiment 1

[0027] The invention discloses a biological bacterial fertilizer prepared by using waste diatomaceous earth in a brewery, which is obtained through the production method of the following steps:

[0028] 1. Pretreatment of waste diatomaceous earth

[0029] Dry the waste diatomaceous earth from the brewery, and the final moisture content is 50%-60%.

[0030] 2. Preparation of mixed bacterial solution:

[0031] Cultivate the biocontrol bacteria Bacillus licheniformis ABTNL-1 and Bacillus subtilis ABTNL-2 respectively in liquid medium, and mix them in equal proportions to prepare a mixed bacterial solution;

[0032] The liquid medium is prepared by dissolving 10.0g of sodium chloride, 10.0g of tryptone, and 5.0g of yeast powder in 1L of distilled water, and sterilizing at 121°C for 20 minutes before use; 10 8 -10 9 CFU·ml -1 .

[0033] 3. Fermentation and condition control

[0034] Inoculate the mixed bacterial solution of biocontrol bacteria: inoculate the mixed bacterial ...

Abstract

The invention discloses a method for preparing bio-bacterial manure by means of brewery waste diatomite. According to the product, mixed bacterium liquid of two antagonistic bacteria of bacillus licheniformis ABTNL-1 and bacillus subtilis ABTNL-2 is inoculated into the brewery waste diatomite, and after fermentation, the bio-bacterial manure is obtained. The bio-bacterial manure obtained through preparation can promote growth of various plants, and can improve the fertilizer retaining performance of soil. The product is simple in production process, wide in raw material source, low in production cost and suitable for large-scale production and reasonably utilizes waste in beer production.

Description

technical field [0001] The invention relates to a bio-organic fertilizer prepared from brewery waste diatomite and a preparation method thereof, belonging to the field of agricultural biotechnology. Background technique [0002] Diatomaceous earth is a natural clay mineral with abundant reserves. It is a siliceous sedimentary rock formed by the consolidation of diatom remains and ooze. Its main chemical composition is SiO 2 , has a unique ordered microporous structure, high porosity, large specific surface area, good adsorption and ion exchange. Using diatomaceous earth as a fertilizer carrier and a controlled release material conditioner can improve the physical properties of fertilizers. Control the release of nutrients in fertilizers, reduce the loss of nutrients in the soil, and improve the utilization rate of fertilizers. [0003] At present, diatomite, as a common filter aid, is widely used in beer production. After diatomite is used in beer production, a large amoun...
