Document Type and Number:
WIPO Patent Application WO/2024/082531
Kind Code:
A1
Abstract:
The present application relates to the field of solid waste treatment, and provides a soil improvement material, a preparation method therefor and a use thereof. The soil improvement material is prepared from the following raw materials in parts by weight: 60- 70 parts waste ammonia adsorbent, 10- 20 parts vegetable glue, 0- 20 parts biochar, 3- 10 parts binder; the waste ammonia gas adsorbent is a waste adsorbent generated by industrial ammonia gas adsorption treatment, and the adsorption matrix thereof is one or more of activated carbon, a molecular sieve and zeolite. The preparation method of the soil improvement material comprises: mixing the raw materials to obtain the soil improvement material. The soil improvement material may be used to improve acidic soil. The soil improvement material provided by the present application effectively uses a waste ammonia gas adsorbent from industrial production to improve the copper mine acidic soil, and solves the problems of land occupation and environmental pollution caused by disposal of waste adsorbent. By means of the coating effect of the vegetable glue, the soil improvement material exhibits excellent slow-release performance, resulting in an improved plant survival rate.
