Embodiment 1

[0034]A soil-fixed ecological restoration agent is prepared from crop waste, fine sand, aluminum sulfate, sodium silicate, expanded perlite, and activated sludge. The raw materials of the soil-fixed ecological restoration agent are calculated as :

[0035] name parts by weight crop waste 65 copies fine sand 15 copies Aluminum sulfate 1 copy Sodium silicate 3 copies expanded perlite 2 copies activated sludge 5 copies

[0036] Specific steps are as follows:

[0037] 1) Mechanically pulverize 65 parts by weight of crop waste to be finely divided into 2 mm or less, completely wet with water so that the water content of the crop waste material is maintained at about 60% to 70%, and stand for 3 days at room temperature;

[0038] 2) Add fermented liquid to the crop wastes that have been processed in the above step 1), and put them into the heat preservation mixer for continuous mixing and stirring for 20 to 30 minutes until fu...

Embodiment 2

[0043] A soil-fixed ecological restoration agent is prepared from crop waste, fine sand, aluminum sulfate, sodium silicate, expanded perlite, and activated sludge. The raw materials of the soil-fixed ecological restoration agent are calculated as :

[0044] name parts by weight crop waste 70 copies fine sand 20 copies Aluminum sulfate 0.5 parts Sodium silicate 1 copy expanded perlite 2 copies activated sludge 10 copies

[0045] Specific steps are as follows:

[0046] 1) Mechanically pulverize 70 parts by weight of crop waste to be finely divided into 2 mm or less, completely wet with water so that the water content of the crop waste material is maintained at about 60% to 70%, and stand for 3 days at room temperature;

[0047] 2) Add fermented liquid to the crop wastes that have been processed in the above step 1), and put them into the heat preservation mixer for continuous mixing and stirring for 20 to 30 minutes until...

Embodiment 3

[0052] 80 crop wastes were mechanically crushed and thinned into blocks of about 0.5 mm, completely wetted with water, so that the water content of the crop waste materials was about 68%, and left to stand for 5 days under normal temperature conditions; The crop wastes are piled into a cone shape, placed in a cool, airtight environment, and the temperature in the crop waste pile is kept at 58°C. The pile is covered with insulation film and other materials to keep moisture and keep warm, and it is left to ferment for 20 days; the fermentation in the above steps is completed The crop waste and 15 parts of fine sand are fully mixed and dried to reduce the moisture in the mixture to 3%; add 1 part of sodium silicate, 1 part of aluminum sulfate, and 2 parts of the mixture processed in the above steps Expanded perlite and 6 parts of activated sludge are fully mixed and the mixture processed in the above steps is crushed again, and passed through a 50-mesh sieve to obtain a soil-fixed...

Abstract

The invention provides a soil fixing ecological repairing agent and a preparation method thereof. The soil fixing ecological repairing agent is prepared by treating crop wastes rich in plant fiber tissues by a program of crushing, refining, wetting, fermenting and drying, then adding a certain propart of fine sand, aluminum sulfate, sodium silicate, expanded perlite and active sludge, and screening. The soil fixing ecological repairing agent, on one hand, enhance drag force and cementation effect among soil blocks and granules to achieve the technical effect of fixing and repairing soil and preventing soil and water loss and transportation, on the other hand, the soil fixing ecological repairing agent adopts effective technical means to avoid the side effects of soil hardening and compaction caused by the soil fixing ecological repairing agent. The soil fixing ecological repairing agent has the advantages of greenness, environmental friendliness, wide source of raw materials, low cost, simple preparation process, convenient use and no side effect.

Description

technical field [0001] It specifically relates to the field of prevention and control of soil water and soil loss, flying dust and blowing sand, and in particular relates to a soil fixing ecological restoration agent and a preparation method thereof. Background technique [0002] The deterioration of the ecological environment is manifested in the destruction of vegetation, soil erosion, desertification and so on. According to the second national land erosion remote sensing survey, the area of ​​soil erosion in my country is 3.56 million square kilometers, and the desertified land is 1.74 million square kilometers. 1.349 million hectares, 2.383 million hectares of land occupied or destroyed by mining activities, with serious vegetation damage. The adverse impact of the deterioration of the ecological environment on human beings is becoming more and more obvious, and it is imperative to increase investment in ecological environment construction to protect the increasingly fra...
