The yeast has the advantages of good osmotic pressure resistance, acid resistance, high metabolic efficiency and the like, can live in water bodies containing substances which are difficult to degrade and organic toxic substances, and has strong decomposition capability on the organic substances.
The microbial compositions in the embodiment are carefully selected, so that the microbes which are beneficial to the purification of the water body can be prevented from carrying out secondary pollution on the water body.
Preferably, in the embodiment, the mixing ratio of the lactobacillus, the bacillus subtilis, the burkholderia, the pseudomonobacterium and the yeast is 3:3:3:1:1, and the whole microbial composition can achieve the optimal water body purification effect through mixing of thalli in different ratios.
In the specific process of manufacturing the composite brick 1, the prepared microorganism composition is soaked in a microorganism culture solution at 15-25 ℃ for about 24 hours, then the microorganism composition is filled in the pores of the composite layer 3, and finally the manufactured composite brick 1 is laid in a water body. The microbial composition is filled in the composite layer 3, and the activity of the microbial composition is not destroyed, and the strength of the composite brick 11 is not affected.
In other embodiments, the proportion of the microbial composition may be determined as desired. For example, the proportion of the microbial composition may be selected according to the pollutant composition in the water body or the ecological environment of the water body.
Preferably, the content of the microbial composition in the composite layer 3 in the embodiment is 0.05% -1%. The content proportion of the microorganisms can be determined according to factors such as the actual size of the composite brick 1, the porosity of the composite layer 3 and the like. By setting the appropriate content proportion of the microbial composition, the microbes can fully utilize the pores in the composite layer 3 to provide a habitat for the microbial composition, so that the composite brick 1 achieves the optimal water body purification capacity.
Specifically, the stone material comprises coarse aggregate or pumice or both aggregate and pumice. Wherein, the aggregate refers to a granular material which plays a role of a framework and a filling function in concrete and mortar. There are two kinds of fine aggregate and coarse aggregate. The diameter of the fine aggregate particles is between 0.16 and 5 mm. Natural sand such as river sand, sea sand, or valley sand is generally used. The coarse aggregate has a particle diameter of more than 5mm, and is commonly used with crushed stones and pebbles. In the embodiment, the coarse aggregate is adopted, the diameter of the coarse aggregate is between 5mm and 20mm, and a large number of pores and a large specific surface area can be formed in the composite layer 3 made of the coarse aggregate, so that a habitat is provided for plants and microorganisms in a water body, and meanwhile, sufficient oxygen is provided for the microorganisms in the composite brick 1. Pumice refers to a mineral formed after cooling volcanic eruption magma. Pumice is called pumice because its main component is silicon dioxide, which is soft in texture and can float on the water surface with a small specific gravity. The pumice stone has the characteristics of light weight, high strength, acid and alkali resistance, corrosion resistance, no pollution, no radioactivity and the like. The pumice has rough surface and porosity up to 71.8-81%, and is a good habitat for microorganisms. In this embodiment, coarse aggregate and pumice are added to the composite layer 3 to increase the porosity of the composite layer 3, so that the composite layer 3 can provide more habitat for microorganisms.
Preferably, in this embodiment, the content of the coarse aggregate in the composite layer 3 is controlled to be between 60% and 80%, and the content of the pumice stone is controlled to be between 4% and 8%. When the composite layer 3 needs more pores, the proportion of the added coarse aggregate is increased, and the proportion of the added pumice is increased; when less porosity is required for the composite layer 3, the addition ratio of the composite layer 3 is reduced, and the addition ratio of the pumice stone is also reduced. In this embodiment, the coarse aggregate is maintained at a high content level, so that the porosity of the composite layer 3 is also maintained at a high level, so as to ensure that the microbial composition has sufficient inhabitation space, and the water body can rapidly flow into the pores to be purified by the microbial composition.
In the embodiment, the porosity of the composite layer 3 can reach 15-30% by arranging the coarse aggregate and the pumice.
In other embodiments, other materials that facilitate microbial habitation may also be included in the stone.
Preferably, the composite layer 3 may also contain a small amount of cement, and the content of the concrete cement may be between 10% and 20%. The cement has certain viscosity, can be used as a viscosity agent to bond pumice, coarse aggregate and the like in the composite layer 3 together, and can also bond the composite layer 3 and the composite brick body 2 together stably. The composite layer 3 contains a small amount of cement because cement particles are fine and have a certain fluidity, so that it is necessary to prevent the cement from filling up the pores in the composite layer 3 and to reduce the habitat of the microbial composition.
In addition, the composite brick body 2 comprises cement, and the cement has certain viscosity and certain strength after solidification, so that the structural strength of the composite brick 1 can be increased. In other embodiments, other materials that are adhesive and that can improve the structural strength of the composite tile body 2 can be included in the composite tile body 2.
The composite brick body 2 is of a rectangular structure so as to be conveniently laid in a water body. The composite layer 3 is also attached to the outer side of the composite brick body 2 and is of a rectangular structure. Specifically, the composite layer 3 may be attached to one side surface of the composite brick body 2, may be attached to a plurality of side surfaces of the composite brick body 2, and may attach the entire composite brick body 2. The more the area covered by the composite layer 3 is, the more the area contacted with the water body is, and the water body can be purified more fully and rapidly. In this embodiment, the composite layer 3 completely covers the composite brick body 2 to achieve a better water purification effect.
In other embodiments, the composite tile body 2 and the composite layer 3 may have other shapes.
In order to make compound brick body 2 also have the hole, can provide habitat for the microorganism, compound brick body 2 still includes coarse aggregate, through the mixture of coarse aggregate and cement for also have the hole in compound brick body 2, provide more habitat for the microorganism. The adding proportion of the concrete cement and the coarse aggregate can be determined according to actual needs, so that the composite brick body 2 is ensured to have certain pores while having sufficient structural strength.
Furthermore, a grid layer 4 is arranged between the composite brick body 2 and the composite layer 3. The mesh layer 4 may be a metal mesh, for example, an iron mesh layer. The composite brick body 2 is completely wrapped by the grid layer 4, and grids are uniformly arranged on the grid layer 4. The grid layer 4 can increase the frictional force outside the composite brick body 2, and improve the adhesiveness of the composite brick body 2, so that the composite layer 3 can be attached to the composite brick body 2 more conveniently and firmly. Meanwhile, the composite brick body 2 can be prevented from being damaged, and the structural strength of the composite brick body 2 is improved.
Optionally, the composite brick 1 is further provided with through holes 5, the through holes 5 are arranged along the length direction of the composite brick 1, and the number and the diameter of the through holes 5 can be determined according to actual needs. 3 through-holes 5 are arranged in the embodiment, and the 3 through-holes 5 are uniformly arranged on the side surface of the composite brick 1 in the length direction. The through hole 5 penetrates through the composite brick body 2 and the composite layer 3. The through holes 5 can enable water to enter the composite layer 3 more easily and contact with the microbial composition more easily, and the purpose of quickly purifying the water can be achieved.
Preferably, the composite brick body 2 is further added with a water reducing agent or a fluidizing agent in the manufacturing process. The water reducing agent or the fluidizing agent is used for improving the fluidity of the concrete mixture. The dosage of the water reducing agent or the fluidizing agent can be determined according to actual needs. When the composite bricks 1 are manufactured in large quantities, since cement is used in a large amount, it is necessary to suppress physical aggregation and chemical aggregation of cement.
