preparation example Construction

[0020] A preparation method for a microcapsule composite microbial agent for purifying water, comprising the following steps:

[0021] S1: Add photosynthetic bacteria, Bacillus subtilis, lactic acid bacteria, yeast, Bacillus megaterium, nitrifying bacteria and Rhodospirillum to the fermentation broth, carry out fermentation, and turn to S2.

[0022] In actual operation, the specific steps of S1 include: adding 10g-1kg photosynthetic bacteria strains, 10g-1kg Bacillus subtilis strains, 10g-1kg lactic acid bacteria strains, 10g-1kg yeast strains, 10g~1kg of Bacillus megaterium strains, 10g~1kg of nitrifying bacteria strains and 10g~1kg of Rhodospirillum strains are fermented and transferred to S2.

[0023] S2: After the fermentation is completed, filter out the solid matter in the current fermentation broth; perform low-temperature concentration on the fermentation broth, and transfer to S3;

[0024] During specific operation, the temperature for low-temperature concentration o...

Embodiment 1

[0030] Embodiment 1 provides a kind of preparation method for the microcapsule composite microbial agent of purifying water body, comprises the following steps:

[0031] Add 1kg of photosynthetic bacteria, 1kg of Bacillus subtilis, 1kg of lactic acid bacteria, 1kg of saccharomyces, 1kg of megaterium, 1kg of nitrifying bacteria and 1kg of Rhodospirillum into 100kg of fermentation broth After the fermentation is completed, the solid matter in the current fermentation broth is filtered out, and the fermentation broth is concentrated at a low temperature at a temperature of 35°C; in the concentrated fermentation broth, the weight ratio of adding to the fermentation broth is 3 ‰ xanthan gum, sodium caseinate with a weight ratio of 1‰ to the fermentation broth, and Tween 80 with a weight ratio of 5‰ to the fermentation broth, stirred and dissolved evenly, spray-dried to make a microcapsule composite bacterial agent.

Embodiment 2

[0033] Embodiment 2 provides a kind of preparation method for the microcapsule compound bacterial agent of purifying water body, comprises the following steps:

[0034] Add 10g of photosynthetic bacteria, 10g of Bacillus subtilis, 10g of lactic acid bacteria, 10g of saccharomyces, 10g of Bacillus megaterium, 10g of nitrifying bacteria and 10g of Rhodospirillum in 100kg of fermentation broth After the fermentation is completed, the solid matter in the current fermentation broth is filtered out, and the fermentation broth is concentrated at a low temperature at a temperature of 25°C; in the concentrated fermentation broth, the weight ratio of adding to the fermentation broth is 1 ‰ xanthan gum, sodium caseinate with a weight ratio of 0.5‰ to the fermentation broth, and Tween 80 with a weight ratio of 3‰ to the fermentation broth, stirred and dissolved evenly, and then spray-dried to make a microcapsule composite bacterial agent.

Abstract

The invention discloses a microcapsule complex microbial inoculant and a preparation method thereof and relates to the technical field of water purification. The preparation method includes: respectively adding photosynthetic bacteria, bacillus subtilis, lactic acid bacteria, saccharomycetes, bacillus megatherium, nitrobacteria and rhodospirillum in fermentation liquor to perform fermentation; filtering solids in the current fermentation liquor after the fermentation, and performing low-temperature concentration on the fermentation liquor; adding xanthan gum, casein sodium and tween 80 into the concentrated fermentation liquor, and spray drying to obtain the microcapsule complex microbial inoculant after stirring and even dissolving, wherein the weight ratio of the xanthan gum to the fermentation liquor is 1-3%., the weight ratio of the casein sodium to the fermentation liquor is 0.5-1%. and the the weight ratio of the tween 80 to the fermentation liquor is 3-5%.. The microcapsule complex microbial inoculant and the preparation method thereof have the advantages that microbial inoculant storage time can be prolonged, the microbial inoculant can be evenly dispersed in water, synergic effects among various microorganisms can be promoted, and purifying efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of water body purification, in particular to a microcapsule composite bacterial agent for water body purification and a preparation method thereof. Background technique [0002] In recent years, with the development of social economy, the construction of cities and the rapid expansion of urban population, the discharge of industrial wastewater, domestic sewage, atmospheric dust and urban garbage from factories and towns along rivers and lakes has increased significantly. However, the construction of environmental infrastructure in most cities is seriously lagging behind, and sewage is often discharged into urban rivers and lakes without treatment, resulting in the deterioration of the water quality of rivers and lakes running through cities and towns, seriously affecting the environmental quality of cities, making more than 80% of my country's cities The water body has been polluted, and there are even season...
