Problems solved by technology

However, industrial by-products usually contain harmful heavy metals and toxic microorganisms, the composition is unstable, and the processing process is complicated. Some organic modifiers need to add alkaline solutions such as potassium hydroxide to adjust the pH, and there are a lot of problems in the actual application process.

Abstract

The invention belongs to the technical field of saline-alkali soil improvement, and particularly relates to a soil improvement restoration agent and a preparation method thereof. The soil improvementrestoration agent is prepared from, by weight, 15-30 parts of a waste solid alkali or solid acid catalyst; 15 to 20 parts of straw; 5-12 parts of compound microorganisms; 10 to 20 parts of vinasse; 15to 20 parts of powdery urea; 10 to 15 parts of animal waste; and 6-12 parts of sawdust. The waste solid alkali or solid acid catalyst, the straw, the vinasse, the sawdust, the animal waste and the like are used as raw materials of the soil conditioner; on one hand, the problem of recycling the waste catalyst is solved, and on the other hand, many cheap materials are turned into wealth and replaceexpensive chemical modifiers, so that the raw material cost is greatly reduced, the solid alkali or solid acid catalyst can be recycled, and a new path is opened up for regeneration of industrial wastes.

Description

technical field [0001] The invention belongs to the technical field of soil improvement in saline-alkali land, and specifically relates to a soil improvement and restoration agent and a preparation method thereof; [0002] It also relates to a method for repairing and improving soil by applying the above-mentioned soil improving and repairing agent; [0003] It also relates to a method for recovering and reusing the solid alkali catalyst or the solid acid catalyst through the soil improvement and restoration method. Background technique [0004] Saline-alkali soil is a type of soil formed by salinization or alkalization, including saline soil, alkaline soil and various saline-alkali soils. In arid and semi-arid areas, the salt contained in the bottom soil and groundwater, due to ground evaporation, will cause the salt water to rise to the surface layer with the capillary action of the soil. After the water evaporates, the salt will remain on the soil surface and accumulate....
