preparation example Construction

[0027] A method for preparing a microbial agent for sustainable dredging and removing black and odorous water bodies provided by the invention comprises the following steps:

[0028] Step 10, prepare plant culture medium: add 100-300 mesh ore powder for planting to the soil for planting green leafy plants, collect the grown green leafy plants and mix them with sterile purified water, and obtain plant medium by crushing and stirring , high-temperature disinfection, cooling to 30-40°C, and standby, wherein the carbon source concentration in the plant medium is 1g / L-13g / L, and the nitrogen source concentration is 0.1g / L-1g / L. The present invention uses ore powder to plant green leafy plants, which can enrich more trace elements during the growth process of the plants, and the content ratio of trace elements meets the needs of the plants themselves. As a plant medium, it is also more conducive to plant sources The cultivation and propagation of microorganisms do not need to add ad...

Embodiment 1

[0044] The raw material components used in this example are: 10.2 parts of ore powder for cultivation, 0.5 parts of plant culture medium, 0.3 parts of plant-derived microorganisms and 89.0 parts of sterile water.

[0045] Add 89.0 parts of sterile purified water for culture into the fermentation vessel, spread 3.4 parts of ore powder for culture on the bottom of the fermentation vessel, and let it stand for 15-30 minutes; add 0.5 parts of plant-derived culture medium and stir evenly; add 0.3 parts of Plant-derived microorganisms, stirred evenly, fermented at a constant temperature of 35°C for 24-48 hours, and aerated with oxygen every 15-30 minutes; the pH value of the liquid in the fermentation vessel was kept between 5.0-6.5.

[0046] Add 4.2 parts of ore powder for cultivation, ferment at a constant temperature of 30°C for 8 to 24 hours, aerate with oxygen every 30 to 60 minutes, and keep the pH value of the liquid in the fermentation vessel between 5.0 and 6.5.

[0047] Ad...

Embodiment 2

[0050] The raw material components used in this example are: 15.0 parts of ore powder for cultivation, 1.0 part of plant culture medium, 0.5 part of plant-derived microorganisms and 60.0 parts of sterile purified water for cultivation.

[0051] The difference from Example 1 is that 5.0 parts of ore powder for cultivation is spread on the bottom of the fermentation vessel, then 6.0 parts of ore powder for cultivation are added, and finally the remaining 4.0 parts of ore powder for cultivation are added.

Abstract

The invention discloses a preparation method of a microbial agent capable of continuously desilting and removing a black and odorous water body. The preparation method comprises the following steps: adding mineral powder for planting into soil for planting green leaf plants, collecting grown green leaf plants, mixing the collected green leaf plants with sterile purified water, crushing and stirring a mixture to obtain a plant culture medium; preparing the following raw materials in parts by weight: 10.2 to 36.0 parts of the mineral powder with 100 to 300 meshes for culturing, 0.5 to 5.5 parts of the plant culture medium, 0.3 to 2.5 parts of plant source microorganisms and 56.0 to 89.0 parts of the sterile purified water for culturing; preparing microbial liquid from the raw materials, fusing the microbial liquid with to-be-treated plant source microbial liquid obtained by collecting and domesticating in an original river branch according to the weight part ratio being 3:7, and finally, mixing a mixed solution with broken ore grains to obtain a finished product. The microbial agent disclosed by the invention can realize instant settlement for taking effect, quick field planting and propagation expanding at the bottom of a river bed and continuous biological deodorization, desilting and water purification within 3 to 6 months, is ecological and environment-friendly, and is suitable for treating the black and odorous water body in the river branch.

Description

technical field [0001] The invention relates to a biological purifying agent, in particular to a preparation method of a microbial bacterial agent for sustainable desilting and removing black and odorous water bodies. Background technique [0002] Urban rivers not only have the function of water supply, but also have become the main discharge sites of urban industrial wastewater and domestic sewage. With the massive discharge of industrial wastewater and domestic sewage, the river will present the characteristics of black and odor. The cause of black and odor is: when a large amount of organic pollutants enter the water body, under the biochemical action of aerobic microorganisms, a large amount of oxygen in the water body is consumed. Transform the water body into an anoxic state, causing a large number of anaerobic bacteria to multiply, organic matter corruption, decomposition, and fermentation to turn the water body black and smelly, organic pollution, ammonia nitrogen, h...
