Embodiment 1

[0027] A method for preparing microbial balls for degrading black and odorous water channel sediment, comprising the following preparation steps:

[0028] 1) Preparation of component A: Mix porous biochar, microbial agent, bran, clay and water in a mass ratio of 4:4:3:1:1 to obtain viscous component A;

[0029] The mixing method of porous biochar, microbial agent, clay and water is as follows: first mix porous biochar and microbial agent evenly, then add bran, clay and water and mix to obtain viscous component A. Mixing the porous biochar with the microbial agent can utilize the porous properties of the biochar to absorb some microorganisms.

[0030] Wherein, the preparation method of the porous biochar is: mix peanut shells and hydrochloric acid according to a mass ratio of 1:1, soak for 24 h, then dry at 120°C for 12 h, and carbonize at 1200°C for 2 hours under the protection of argon. h, ground into powder after standing to room temperature, and passed through a 100-mesh s...

Embodiment 2

[0036] The difference from Example 1 is that 1) the porous biochar, microbial agent, bran, clay and water in component A are mixed according to the mass ratio of 4:3:2:1:2, and the microbial agent is effective The number of live bacteria is 2×10 8 ; 2) The mass of sucrose is 2g.

Embodiment 3

[0038] The difference from Example 1 is that 1) the porous biochar, microbial agent, bran, clay and water in component A are mixed according to the mass ratio of 5:5:2:0.5:0.5, and the microbial agent is effective The number of live bacteria is 2×10 8 ; 2) The mass of sucrose is 1.35g.

Abstract

The invention relates to a method for preparing microbial pellets for degrading black and odorous water channel sediment, comprising the following preparation steps: 1) making porous biochar, microbial agent, bran, clay and water according to (3‑5):( 3-5):(2-4):(0.5-2):(0.5-2) by mass ratio mixing to obtain component A; 2) Inject 0.5-4mL hydrogen peroxide into a spherical mold with an inner diameter of 1-2cm, and Add 1-10g of sucrose to the mixture, mix evenly, and let stand to obtain the hydrogen peroxide inner core wrapped with crystalline sucrose; 3) Preparation of microbial balls: wrap the hydrogen peroxide inner core with crystalline sucrose prepared in step 2) with component A, and air-dry at room temperature , to obtain microbial balls. The microbial balls of the present invention promote the growth of sediment microbial flora, thereby increasing the biodegradation rate and rapidly reducing the black and odorous water sediment, and have the advantages of good ecology, high stability, good effect, and low cost.

Description

technical field [0001] The invention belongs to the field of treatment of black and odorous water bodies, and in particular relates to a microbial ball for degrading river sediment of black and odorous water bodies, a preparation method and application thereof. Background technique [0002] Black and odorous water is an extreme phenomenon of water pollution. It is mainly caused by exogenous organic matter and ammonia nitrogen consuming oxygen in water, resulting in hypoxia in water. It is also related to water eutrophication and sediment deposition. [0003] Sediment is the place where a large amount of pollutants in the water body deposit and accumulate, and it is one of the important places where various pollutants belong. Under a series of biological, chemical, and physical conditions, the bottom mud exchanges with the pollutants adsorbed on the bottom mud, and a large amount of pollutants are released into the overlying water, causing secondary pollution of the water bod...
