Method for producing a sand aggregate

Abstract

The present invention relates to a method for producing a sand aggregate, comprising: (a) a step of producing organic waste powders or by-product powders; (b) a step of mixing the organic waste powders or the by-product powders produced in step (a) with soil microbes; (c) a step of mixing the resulting material obtained in step (b) with sand to inoculate the sand with the soil microbes; and (d) a step of supplying water to the resulting material obtained in step (c), and aggregating particles of the organic waste powders and the sand by the growing mycelia of the soil microbes. The present invention produces a sand aggregate (preferably, sand cake, precast pavers or bricks, etc.) or reforms (preferably, fertilizes) sand using organic waste (or by-products), to reutilize waste (or by-products) and to thus prevent soil or water from being contaminated by organic waste (or by-products). Further, when the present invention is applied to the sand in which plants grow poorly, the sand is fertilized to promote the growth of symbiotic microorganisms, and to raise plants and suppress the use of chemical fertilizers and agricultural pesticides, thus activating environmentally-friendly green farming. Meanwhile, when the present invention is applied to the desert of China, which causes yellow dust storms, sand and red clay are provided with anti-scattering properties, to thereby prevent yellow dust storms and environmental contamination and damage to animals and plants caused by the yellow dust storms.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing sand aggregates, a method for improving sand and a method for agglomerating and solidifying desert surfaces. 【Background technique】 [0002] Generally speaking, the so-called dust phenomenon refers to the following phenomenon: due to the strong wind blowing behind the front of the cold front in the desert areas of China and Mongolia in the middle of the Asian continent, the Loess Plateau in the middle reaches of the Yellow River, or the cold front of the Inner Mongolia Plateau or the warm current caused by the terrain A large amount of dust is raised, and it gradually falls to the ground while moving in the air with the wind. This phenomenon was first recorded in Korea in the period of King Adara of the Silla Period of the Three Kingdoms (AD 174). At that time, it was recorded that the gods were angry and scattered dust that was neither rain nor snow. [0003] This kind of sand and dust phenomenon ...

Problems solved by technology

[0003] This kind of sand and dust phenomenon occurs repeatedly every year, and its hazards are increasing year by year, leading to a series of environmental pollution and health problems, agricultural problems or water pollution, etc., which have seriously affected the country's industrial facilities and infrastructure.

[0004] However, China, South Korea, Japan, and the United States, which are most affected by it, have not been able to launch a fundamental solution to the problem, and they have to stand by and watch this huge influence.

[0005] Of course, South Korea or Japan, represented by China, have introduced methods such as planting trees in the desert in order to prevent desertification and solve the problem of yellow sand. However, due to the lack of water resources in the desert, trees are not suitable for growth, which makes it difficult to put them into practice.
