Embodiment 1

[0032] Example 1: Microorganisms: Bacillus subtilis, Bacillus thuringiensis and Bacillus sphaericus were mixed in a mass ratio of 1:7:20, and the content of the microorganisms accounted for 20wt% of the entire concrete.

[0033] Ordinary cement: 300kg; 10mm particle size natural gravel: 3000kg; diluted mixture: 400cc;

[0034] After the above materials are mixed, shaped, cured, and then the concrete is hardened.

Embodiment 2

[0035] Example 2: Microorganisms: Bacillus subtilis, Bacillus thuringiensis and Bacillus sphaericus were mixed in a mass ratio of 1:5:15, and the content of the microorganisms accounted for 20wt% of the entire concrete.

[0036] Ordinary cement: 300kg; 10mm particle size natural gravel: 3000kg; diluted mixture: 400cc;

[0037] After the above materials are mixed, shaped, cured, and then the concrete is hardened.

Embodiment 3

[0038] Example 3: Microorganisms: Bacillus subtilis, Bacillus thuringiensis and Bacillus sphaericus were mixed in a mass ratio of 1:5:15, and the content of the microorganisms accounted for 25wt% of the entire concrete.

[0039] Ordinary cement: 250kg; 10mm particle size natural gravel: 2500kg; diluted mixture: 350cc;

[0040] After the above materials are mixed, shaped, cured, and then the concrete is hardened.

Abstract

The invention provides a concrete stone block for water quality purification and a manufacturing method thereof. The concrete stone block contains a mixture of microbial florae, wherein the microbial florae comprise hay bacillus, Entobakterin and bacillus sphaericus according to the mass ratio of (1 to 20):(25 to 50):(0.1 to 100) or (25 to 50):(1 to 20):(20 to 100) or (1 to 50):(1 to 20):(25 to 100). The mixture of the microbial florae in the concrete stone block for water quality purification propagates quickly when contacting water and takes contaminants in sewage as bait, and the microbes can adsorb and decompose the contaminants in the sewage when dispersed in the sewage, and thus, the aim of water quality purification is fulfilled. Besides, the concrete stone block is less in investment cost, can resist high temperature and various acidic and alkaline environments, is suitable for controlling all sorts of sewage with different water qualities, is wide in application range and high in persistency, and can meet the requirements on sewage control at present.

Description

technical field [0001] The invention relates to a concrete stone for water purification and a manufacturing method thereof, in particular to a concrete cement stone for water purification containing microorganisms and a manufacturing method thereof. Background technique [0002] Water is the source of life. However, with the continuous development of society, the discharge of harmful substances such as heavy metals and their compounds in industrial wastewater and domestic wastewater, as well as various wastes and radioactive substances, has become increasingly serious for water pollution. , water pollution has become the number one environmental problem in recent years. [0003] The discharge of pollutants into the water source seriously damages the water quality, which not only causes the river water to become black and smelly, destroys the beauty of the environment, and seriously affects people's lives, but also the polluted water source will interfere with the migration a...
