Problems solved by technology

Usually there are self-purifying microorganisms in rivers with better ecology and less pollution, but the self-purifying function has been lost in polluted rivers, self-purifying microorganisms are lacking or the amount of bacteria is too small, and microorganisms in nature can be artificially cultivated, isolated and domesticated , utilized, and further used for environmental governance are very few

preparation example Construction

[0042] The present invention also provides a kind of preparation method of the composite microbial bacterial agent of treating polluted water body, comprises the following steps:

[0043] S10: configuring culture medium;

[0044] S20: Inoculation: add Bacillus subtilis, Paracoccus denitrificans, Clostridium papiersolvee, Bacillus licheniformis, photosynthetic bacteria, actinomycetes, denitrifying bacteria, nitrobacterium and nitrosobacillus to the culture medium prepared in S10 to ferment together Afterwards, filter to obtain filtrate;

[0045] S30: Dilute the filtrate prepared in S20 with a protective solution.

[0046]Preferably, in step S10, the culture medium is prepared in parts by weight, including 15-18 parts of sweet potato powder, 20-30 parts of tempeh, 3-5 parts of beef extract, 3.5-4.5 parts of yeast extract, and 0.5-1 part of sodium alginate , 0.01-0.03 parts of dipotassium hydrogen phosphate, 0.02-0.05 parts of glutamic acid, 0.5-1 part of sodium chloride, 0.01-...

Embodiment 1

[0059] The percentage by weight of microorganisms in the compound microbial bacterial agent for controlling polluted water is as follows: a mixture of 3% Rhodopseudomonas zazena, 35% Bacillus subtilis and Bacillus licheniformis, wherein the colony ratio of Bacillus subtilis and Bacillus licheniformis is 1 : 1. Biological enzyme composed of 25% Nitrosobacillus, 25% Nitrobacter, 5% Denitrifying Bacillus and 7% lipase and subtilisin.

Embodiment 2

[0061] The percentage by weight of microorganisms in the compound microbial bacterial agent for controlling polluted water is as follows: the mixture of 15% Rhodopseudomonas zenezensee, 20% Bacillus subtilis and Bacillus licheniformis, wherein the colony ratio of Bacillus subtilis and Bacillus licheniformis is 2 : 1. Biological enzyme composed of 20% Nitrosobacillus, 15% Nitrobacter, 25% Denitrifying Bacillus and 5% lipase and subtilisin.

Abstract

The invention provides a composite microbial agent for treating contaminated water and a preparation method thereof. The composite microbial agent for treating contaminated water comprises photosynthetic bacteria, bacillus, nitrosobacter, nitrobacter, denitrifying bacillus and biological enzymes. The photosynthetic bacteria, bacillus, nitrosobacter, nitrobacter and denitrifying bacillus are obtained by culture and domestication of microbes extracted from natural water, and the combined bacteria have characteristics of species diversity, high activity, high efficiency and good stress resistance. The composite microbial agent can effectively stimulate the activity of microorganisms in water, accelerate the growth and reproduction of microorganisms and provide a good support for in-situ remediation in treatment on waste water in rivers, lakes and rivers.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composite microbial agent for treating polluted water and a preparation method thereof. Background technique [0002] River water pollution has become the main factor affecting regional socio-economic development and restricting the improvement of people's living standards. Surveys have shown that more than 90% of the rural water ecology in the Yangtze River Delta region has lost its basic functions, urban and rural rivers have been severely degraded due to pollution and ecosystems, and the water quality of the rivers has basically fallen into Class V or worse. Most rivers are seriously polluted, rich Nutritization, the most important pollution indicators are permanganate index and ammonia nitrogen. In addition, most of the river water turns black and smelly, and the pathogenic bacteria exceed the standard, resulting in a severe environmental and ecological situation, ...
