Embodiment 1

[0080] At the end of April in spring, at the southern edge of the Gurbantunggut Desert in the Junggar Basin, Xinjiang, the 150-group sandy land environment in Shihezi City will be operated according to the following steps:

[0081] Preparation of soil improver: take 1000kg as the base, weigh 100 parts of raw material sand according to parts by weight, 5 parts of grease by-product sludge and oil foot, 5 parts of wine residue, 10 parts of sludge with 10% water content, fly ash 10 parts, 10 parts of weathered coal, fully stirred at a speed of 2000r / min for 15 minutes to obtain a uniformly mixed soil conditioner;

[0082] The obtained soil improver is spread on the surface of the sand, and the covering thickness is 10cm;

[0083] Drip irrigation is carried out on the covered sandy land. The wetness of the ground is 10cm of the thickness of the covered soil improver. After two days under outdoor conditions, the surface and underground sand are in a wet state. The soil improver has go...

Embodiment 2

[0086] In autumn and August, at the southern edge of the Gurbantunggut Desert in the Junggar Basin, Xinjiang, the specific operation of the 150-group sandy land environment in Shihezi City is carried out according to the following steps:

[0087] Preparation of soil improver: take 1000kg as the base, weigh 100 parts of raw material sand, 10 parts of grease by-product sludge and oil foot, 10 parts of wine residue, 15 parts of sludge with water content of 20%, 15 parts of fly ash 15 parts of weathered coal, stirred for 15 minutes at a speed of 2000r / min to obtain a uniformly mixed soil conditioner;

[0088] The obtained soil improver is spread on the surface of the sand, and the covering thickness is 15cm;

[0089] Drip irrigation is carried out on the covered sandy ground. The wetness of the ground is 15cm of the thickness of the covered soil improver. After two days under outdoor conditions, the surface and underground sand are in a wet state. The soil improver has good water ...

Embodiment 3

[0092] In April in spring, at the southern edge of the Gurbantunggut Desert in the Junggar Basin, Xinjiang, the specific operation of the 150-group sandy land environment in Shihezi City is carried out according to the following steps:

[0093] Preparation of soil improver: take 1000kg as the base, weigh 100 parts of raw material sand according to parts by weight, 15 parts of grease by-product sludge and oil foot, 20 parts of wine residue, 20 parts of sludge with 30% water content, fly ash 15 parts, 20 parts of weathered coal, stirred at a speed of 2000r / min for 15min to obtain a uniformly mixed soil conditioner;

[0094] Spread the soil improver on the surface of the sand, with a thickness of 15cm;

[0095] Drip irrigation is carried out on the covered sandy land. The wetness of the ground is 15cm of the thickness of the covered soil improver. After two days under outdoor conditions, the surface and underground sandy land is in a wet state. The soil improver has good water re...

Abstract

The invention relates to a method for utilizing waste as a soil improvement agent for remediating desertification soil. The soil improvement agent in the method is prepared by evenly mixing sand grains or sandy soil, grease by-product greasy filth and oil foots, liquor residues, sludge, coal ash and decomposed coal proportionally, then, the soil improvement agent coats the surface of desert or sand, watering or drip irrigation watering is performed, drought-enduring plants or crops are planted on a sandy block to be remediated and can grow well, meanwhile, the soil skin effect can be formed ona desert layer due to coating of the soil improvement agent, and the partial-curing effect is achieved on desert or sand. According to the method, waste is reasonably utilized again, the method conforms to the recycling economic concept, and the problem that environment contamination is caused by waste is solved. The waste obtained after industrial and agricultural production is adopted as raw materials for remediating desert and sand, energy conservation and emission reduction are composited, and the method conforms to the circular economy concept and natural laws.

Description

technical field [0001] The invention relates to a method for treating desertified soil by using waste as a soil improver. Background technique [0002] Desertification and desertification are serious and major problems facing mankind today, leading to soil "degradation" or "desertification" and causing a series of hazards including sand flow and sand dune forward movement, covering farmland, silting rivers, reservoirs, canals, and burying roads, etc. System degradation, loss of land resources, and economic stagnation in related areas. How to effectively control desertification has always been a global problem. Desert sand is not suitable for plant growth because of its rough particles, fast water seepage, and poor water retention. Land desertification and desertification are one of the most important ecological environmental problems in the world. The forms of land desertification and desertification in my country are very severe, and the area of ​​desertified land is expan...
