Embodiment 1

[0026] A kind of ecological soil restoration method, comprises the steps:

[0027] S1 selects 200 parts by weight of agaricus, naturally air-dries and mechanically crushes;

[0028] S2 adds 35 parts by weight of a cross-linking agent and 75 parts by weight of water to the crushed agaric material, heats up and stirs;

[0029] After S3 is lowered to room temperature, continue to stir, filter the remaining crosslinking agent, dry it, and crush it until the particle size is less than 40 mesh to obtain the soil remediation agent;

[0030] S4 applies a soil remediation agent on the surface of the heavy metal contaminated soil, and mixes evenly the 20cm thick soil on the surface of the contaminated soil with the applied Geliflower powder by plowing;

[0031] After 1 to 3 weeks in S5, the stabilization of heavy metals is achieved, that is, the restoration of ecological soil is completed.

[0032] Among them, the heating temperature in S1 is 45°C, the stirring speed in S2 is 100rpm, ...

Abstract

The invention relates to an ecological soil remediation method which comprises the following steps: S1, selecting 200 parts by weight of gelidium amansii, and naturally air-drying and mechanically crushing the gelidium amansii; s2, adding 35 parts by weight of a cross-linking agent and 75 parts by weight of water into the crushed gelidium amansii material, heating, and stirring; and S3, cooling to room temperature, continuously stirring, filtering the residual cross-linking agent, drying, and crushing until the particle size is less than 40 meshes to obtain the soil remediation agent. S4, apllying a soil remediation agent to the surface of heavy metal contaminated soil, and mixing the soil with the thickness of 20 cm on the surface layer of the contaminated soil and the applied gelidium amansii powder evenly in a ploughing mode; and S5, completing ecological soil remediation after 1-3 weeks. According to the ecological soil remediation method, the remediation efficiency is high, natural gelidium amansii serves as the raw material, no secondary pollution is caused to the soil, the remediation cost is low, and the remediation period is short.

Description

technical field [0001] The invention relates to an ecological soil restoration method. Background technique [0002] Soil is the resource that human beings rely on for survival, and it is also the most recyclable resource in nature. Due to the continuous development of modern industry, a large amount of heavy metals have entered the soil, resulting in serious deterioration of the soil. The accumulation and migration of heavy metals in the soil not only endangers regional ecological security and affects the growth and development of animals and plants, but also enters the human body through the food chain, endangering human health in exposed areas, leading to some chronic diseases, deformities, and cancers. The discharge of waste water, waste gas, and waste slag produced in mining areas and smelting areas pollutes the local soil and is prone to heavy metal pollution in the soil. Whether the heavy metal content in plants in these areas exceeds the standard has always been a co...
