Embodiment 1

[0039] In the present embodiment, the composition (by volume percentage) of microorganism joint plant type compound deodorant is as follows:

[0040] Bacillus subtilis fermentation broth 12%;

[0041] Alcaligenes faecalis fermentation broth 12%;

[0042] Friendly Gordonia Ferment Broth 7%;

[0043] Lactobacillus casei fermentation broth 7%;

[0044] Saccharomyces cerevisiae fermentation broth 22%;

[0045] Yucca solution 36%;

[0046] Osmanthus essential oil 4%.

[0047] Among them, Bacillus subtilis, Lactobacillus casei and Saccharomyces cerevisiae were purchased from Beina Biobank, the preservation number of Bacillus subtilis was BNCC337380, the preservation number of Lactobacillus casei was BNCC134415, and the preservation number of Saccharomyces cerevisiae was BNCC336505; Gordonia friendly was purchased from China Industrial Microorganism Culture Collection Management Center, the preservation number of Alcaligenes faecalis is CICC 23636, and the preservation number of G...

Embodiment 2

[0055] This example is basically the same as Example 1, except that the formula has been slightly adjusted. In this example, the composition (percentage by volume) of the combination of microorganisms and plant-type composite deodorants is as follows:

[0056] Bacillus subtilis fermentation broth 15%;

[0057] Alcaligenes faecalis fermentation broth 15%;

[0058] Friendly Gordonia Ferment Broth 8%;

[0059] Lactobacillus casei fermentation broth 8%;

[0060] Saccharomyces cerevisiae fermentation broth 24%;

[0061] Yucca solution 27%;

[0062] Osmanthus essential oil 3%.

Embodiment 3

[0064] This example is basically the same as Example 1, except that the formula has been slightly adjusted. In this example, the composition (percentage by volume) of the combination of microorganisms and plant-type composite deodorants is as follows:

[0065] Bacillus subtilis fermentation broth 10%;

[0066] Alcaligenes faecalis fermentation broth 10%;

[0067] Friendly Gordonia Ferment Broth 6%;

[0068] Lactobacillus casei fermentation broth 6%;

[0069] Saccharomyces cerevisiae fermentation broth 18%;

[0070] Yucca solution 45%;

[0071] Osmanthus essential oil 5%.

Abstract

The invention relates to the field of water environment protection, in particular to a microbial combined plant-type composite deodorant for black and odorous river surges and a preparation method thereof. The deodorant of this scheme is composed of 50%-70% of microbial fermentation liquid and 30%-50% of plant solution by volume percentage. The microbial fermentation broth contains Bacillus subtilis fermentation broth, Alcaligenes faecalis fermentation broth, Gordonia friendly fermentation broth, Lactobacillus casei fermentation broth and Saccharomyces cerevisiae fermentation broth; the plant solution is composed of yucca solution and osmanthus essential oil. The synergistic effect of each component solves the technical problem that a single deodorant cannot meet the requirements of purification treatment. This scheme can be applied to deodorization practices in places such as black and odorous rivers, garbage transfer stations, and black and odorous river sediments.

Description

technical field [0001] The invention relates to the field of water environment protection, in particular to a microbial combined plant-type composite deodorant for black and odorous river surges and a preparation method thereof. Background technique [0002] With the rapid development of urbanization and industrialization in our country, the urban environment has been severely damaged, and the pollution of water environment has become increasingly serious. Urban black and odorous water not only affects the appearance of the city, but also endangers the health of residents through the transmission of the food chain. Therefore, there is an urgent need to develop a green, efficient and durable black and odor treatment method for black and odorous rivers in cities and towns. [0003] The occurrence of black and odorous rivers in cities and towns is mainly due to the sharp decrease of dissolved oxygen in the water body, which intensifies the activity of anaerobic odor-producing ...
