Embodiment 1

[0043] Prepare the microbial mixed bacterium powder according to the following method:

[0044] (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.

[0045] (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

[0050] Prepare microbial concrete bricks (30 brick parts) as follows:

[0051] (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;

[0052] (2) Pour the base material composed of the above-mentioned mixed microbial bacterium liquid, cement 20kg, gravel 100kg, and sawdust 0.2kg into the base material mixer through the lifting funnel, and stir for 5 minutes;

[0053] (3) Transport the base material to the base material hopper of the forming machine through a belt conveyor, turn on the forming machine, add the base material into the mould, and press down on the upper head of the mold for 5 seconds to obtain a semi-finished brick;

[0054] (4) Harden the semi-finished bricks in a natural state for 7 days to obtain 30 finished microbial concrete bricks.

Embodiment 3

[0056] Get the water tank of two volumes 2m * 0.5m * 0.6m, put into the microbial concrete brick that a piece of embodiment 2 makes in the 1# groove, put into a size, shape all and according to the method for embodiment 2 in the 2# groove The obtained microbial concrete bricks are the same but do not contain common concrete bricks with mixed microorganisms. Into the two tanks, an equal amount of lake water and a small amount of lake bottom silt from the heavily polluted waters at the edge of Taihu Lake (inferior water quality of the fifth category) are injected into the two tanks.

[0057] After one week, the water quality in the 1# tank became colorless, transparent and clear, while the water quality in the 2# tank was light yellow with a little turbidity; and the total nitrogen removal rate in the 1# tank was 58%, while the 2# # The total nitrogen removal rate in the tank is 47.9%. This shows that the microbial concrete brick of the present invention has good pollutant adsor...

Abstract

The invention discloses a microorganism concrete brick and a preparation method thereof. The microorganism concrete brick is formed by mixing cement, gravel, sawdust (or straw scraps, scraps of paper, and the like), mixing mixed microorganism with water according to a certain proportion, forming by a mold and then naturally hardening, wherein the mixed microorganism comprises six floras including bacillus, nitrobacteria, photosynthetic bacteria, saccharomycetes, lactobacillus and actinomycetes. The microorganism concrete brick has excellent water quality purifying function, can continuously play roles for a long time, and is widely applicable to purify various water qualities such as rivers, lakes, canal water, swimming pools, fishponds and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a microbial concrete brick containing water-purifying mixed microorganisms and a preparation method thereof. Background technique [0002] Ecological concrete products are a new type of environmentally friendly products that have attracted more attention in recent years. It is mainly through increasing the pores inside the concrete products and adding a certain amount of organic fertilizers, plant seeds and other ingredients to strengthen the bank and embankment, improve the ecological effects. However, there is no ecological concrete product used in the field of water treatment technology in China at present, and there is no ecological concrete product that functions by adding microorganisms therein. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a widely used microbial concrete brick ...
