Embodiment 1

[0047] Prepare the microbial mixed bacterium powder according to the following method:

[0048] (1) Bacterial strain collection: the soil, water, silt in saline-alkali land, coastal tidal flat areas, and activated sludge from sewage treatment plants are used as samples for collecting bacterial strains.

[0049] (2) Separation and screening: using the coating method or the mixed bacteria method, through the three steps of plate inoculation, streak separation and purification, the samples containing bacillus, nitrifying bacteria, photosynthetic bacteria and actinomycetes are directional isolated from the collected samples. , yeast, and lactic acid bacteria flora; then inoculate the above six flora into triangular flasks filled with artificially simulated sewage, respectively use a constant temperature shaker to cultivate the aerobic bacteria in each flora, and use a constant temperature incubator to stand still. The anaerobic bacteria in each flora are cultured in a closed manne...

Embodiment 2

[0054] Prepare lightweight ecological concrete bricks (type A) (30 bricks) as follows:

[0055] (1) Get 1 kg of the mixed microbial bacterial powder prepared in Example 1, premix it with 1.2 kg of water for 5 hours, and configure it as a mixed microbial bacterial liquid;

[0056] (2) Combine the above-mentioned mixed microbial bacterial liquid with 20kg of cement, 5.6kg of perlite, and 0.2kg of sawdust to form a base material, and stir evenly for about 5 minutes;

[0057] (3) Add the stirred base material into the mould, and press down on the mould's upper head for 5 seconds to obtain a semi-finished brick;

[0058] (4) Harden the semi-finished bricks in a natural state for 7 days to obtain 30 finished lightweight ecological concrete bricks (Type A).

Embodiment 3

[0060] Prepare lightweight ecological concrete bricks (type B) (30 bricks) as follows:

[0061] (1) Get 2kg of the mixed microbial bacterial powder prepared in Example 1, premix it with water 1.2kg for 5 hours, and configure it as a mixed microbial bacterial liquid;

[0062] (2) Combine the above-mentioned mixed microbial bacterial liquid with 20kg of cement, 2.8kg of perlite, 50kg of gravel, and 0.2kg of wood chips to form a base material, and stir evenly for about 5 minutes;

[0063] (3) Add the stirred base material into the mould, and press down on the mould's upper head for 5 seconds to obtain a semi-finished brick;

[0064] (4) Harden the semi-finished bricks in a natural state for 7 days to obtain 30 finished lightweight ecological concrete bricks (type B).

Abstract

The invention discloses a light ecological concrete brick and a preparation method thereof. The light ecological concrete brick is formed by that cement, gravel, pearlite or expanded vermiculite, saw dust (or straw dust, paper scrap and the like), mixed microorganism and water are mixed at certain ratio, are shaped by a mould and are naturally hardened, wherein the mixed microorganism comprises six floras, i.e. bacillus, nitrobacteria, photosynthetic bacteria, saccharomycete, lactic acid bacteria and actinomycete. The light ecological concrete brick of the invention has favourable and long-lasting water purification function because of containing multiple microorganisms and can suspend and even float on the water because of containing light and porous pearlite or expanded vermiculite components with strong adsorption force, which is more favourable for the apposition growth of the microorganism and enlarges contact area with water. The invention can be widely applied on purifying various kinds of water, such as rivers, lakes, ditch water, swimming pools, aquariums and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a lightweight ecological concrete brick and a preparation method thereof. Background technique [0002] Ecological concrete products are a new type of environmentally friendly products that have developed rapidly in recent years. It is mainly through increasing the internal pores of concrete products and adding a certain amount of organic fertilizers, plant seeds and other ingredients to improve soil and fertilization. Dam protection, ecological improvement, etc. However, ecological concrete products specially used for water treatment are very rare at present, and the ingredients added are organic fertilizers, plant seeds, etc., which will continue to be exhausted with the function, so they can only be used in a short period of time. It works internally, and its effectiveness cannot be maintained for a long time. Microorganisms exist widely in nature and have strong sel...
