Embodiment 1

[0033] An efficient soil repair material, the repair material is composed of straw glue, bentonite, slaked lime, polyacrylamide, potassium methyl silicate, and gypsum powder, and the straw glue is made from natural straw fibers through aging, gelatinization and grinding. Concrete preparation steps are as follows:

[0034] (1) Mix the natural straw fiber and the straw decomposing agent evenly according to a certain weight part, stack them into stacks, place them in the open air for fermentation and aging, and then add modified silica gel, sodium chloride and chloride to the mature straw fibers. Calcium, heated and pressurized in a flat vulcanizer to gelatinize the straw fiber, then dried and crushed to obtain powdery straw glue; wherein, 67 parts by weight of natural straw fiber, 2 parts by weight of straw decomposing agent, 20 parts by weight of modified silica gel, 1 part by weight of sodium chloride, and 1 part by weight of calcium chloride;

[0035] (2) Mix the straw glue ...

Abstract

The invention relates to a high efficiency soil remediation material, which is composed of straw gum, bentonite, slaked lime, polyacrylamide, potassium methylsilicate and gypsum powder. The straw gumis prepared by maturation, colloidization and grinding of natural straw fiber. The soil remediation material prepared according to the invention can realize stable adsorption of heavy metals in soil,has long curing time, no "secondary pollution" problem, and no influence on soil structure and fertility, also the preparation process is simple, the operation difficulty is small, the raw materials are easily available, and the cost is low, therefore the high efficiency soil remediation material can be popularized and applied on a large scale.

Description

technical field [0001] The invention relates to a high-efficiency soil restoration material. Background technique [0002] Soil is the material basis for human survival and development, and the basic material for agricultural production. With the rapid development of urbanization and the continuous improvement of the level of industrialization, as well as human activities such as mineral development, metal smelting, sewage irrigation, and chemical fertilizer and pesticide application, pollutants containing heavy metals enter the soil, causing soil pollution, soil degradation, and ecological damage. , and eventually enter the top of the food chain - the human body, thus endangering human health and life safety. After heavy metals enter the soil, they cannot be eliminated by the soil itself but can only be passively adsorbed in the soil, which has become one of the main factors of heavy metal pollution. In addition, the nature of the heavy metal itself and the characteristic...
