Technology Name

Technical principle

After mixing solid waste (fly ash, coal gangue, desulfurization gypsum, coal slime slag, slag), add A, B, C activators to activate the activity of solid waste substances and increase the performance of active ingredients and nutrients to the soil.It is a mixed (adjusted density) soil that combines different components, structures, PH, specific gravity and shapes of solid waste into one, and activates the activity of minerals to restore the original state of the soil, and improves the nutrient composition of the repair fertilizer to the original soil.The new technology uses the solid waste structure to increase the water-demanding adsorption capacity and ensures that the repaired soil can withstand drought for 3-5 months (without watering).A new structural technology that can absorb moisture in the air when the soil is repaired without rain and drought, and can also absorb the wet water under the ground and increase the drought resistance time.A, B, C and new technology regulators are adopted to solve the theory of nutrient in solid waste and soil stacking density, to ensure the restoration of the original soil junction with oxygen supply technology up and down, and to block the problem of acid, saline and alkali returning. (World Problems;)

Scope of application

Saline land, desert land, sandy land, acid land, ecological restoration soil in mining areas, etc.

Process flow and description

Description: The process of material mixing, activation, spraying, adsorption, re-mixing and stirring is used to achieve the process of transforming solid waste materials into suitable soils. After being transformed into mineral soils, the surface activity of material B is improved, soil nutrients are increased, and organic matter is achieved. 20-45. The water release and water retention rate reaches 78%, which is twice the water retention rate of ordinary natural soil.

Process flow: a powder standard - fly ash 180 mesh (coarse ash, tertiary ash) gas slag--b, coal gangue 0.2-9 mm--c, bottom slag 1-5 mm--d, coal washing slime Slag 50 mesh-2.6mm--e, inferior, lignite below 6mm--f, A material--G, b, c, d materials are determined separately.

Process flow:jaw crushing--double roll mill(For convertible interior cars only)--Rotary kiln mixing (normal temperature)--Conditioner--Nanochemicals--Intermediate (automatic spray type)--detect--material warehouse--automatic packaging--product.

recipe selection :Gangue 25%--Fly ash 35%--Desulfurized gypsum 12%--Bottom slag 25%--A material 12%--B material 3%--C additive 1.5%

Formula and process flow:

A. Screening - mixing - conditioning - granulation - kiln drying - packaging

B. Screening - rotary mixing - rotary kiln mixing - packaging

C. Screening-Mixing-Nanochemical-Spiral Discharging-Packaging

Promotion prospects

It is the first domestic company to create artificial soil from solid waste to replace soil. The new technology (patent) solves the mass consumption and resource utilization of solid waste, and improves the economic value; reduces the occupation of land, increases and adds new soil (turns deserts into oasis, salt-alkali into cultivated land), solves environmental pollution, Protect the ecological environment; empty the solid waste dump site and add new land for reuse, saving the country solid waste disposal fees; make solid waste resources, high value, carbon reduction, and a new way of circular economy.Innovative technology: Combined with ecological restoration and desert restoration, it also has the development of vegetable sparse greenhouses, combined with photovoltaic green power, and complementary agriculture and light.Last year, Ordos tested more than 3 mu of land, and the results were very good. Next month, it will develop 20 mu of land in Shuozhou and 300 mu of land in Wushen Banner. The technology is unique in China.
