Abstract

The invention belongs to the technical field of soil remediation agents, and discloses a nickel-contaminated soil remediation material and a preparation method thereof. The nickel-contaminated soil remediation material is prepared from the following components in parts by weight: 200-300 parts of a base material, 2-5 parts of nitro copper humate, 1-3 parts of sulfur, 2-8 parts of disodium EDTA, 7-13 parts of citric acid, 5-7 parts of trace elements, 5-10 parts of chitin, 16-24 parts of tourmaline, 4-8 parts of chitosan, 60-70 parts of humic acid and 3-8 parts of an activator. According to thenickel-contaminated soil remediation material and the preparation method thereof, the pollution is low, the fertility of soil can be effectively improved, meanwhile, soil nitrite and nickel metal canbe highly removed, the activity of soil is improved, soil is rapidly purified and remediated, the preparation method is simple, raw materials are easy to obtain, and the nickel-contaminated soil remediation material is suitable for large-scale popularization in rural areas.

Description

technical field [0001] The invention relates to the technical field of soil remediation agents, in particular to a nickel-contaminated soil remediation material and a preparation method thereof. Background technique [0002] Soil heavy metal pollution refers to the phenomenon that human activities bring heavy metals into the soil, such as nickel metal, causing the content of heavy metals in the soil to be significantly higher than its natural background value, causing ecological damage and environmental quality deterioration. With the rapid population growth and the continuous expansion of industrial and agricultural production, the situation of heavy metal pollution in soil is becoming more and more severe, and the problems caused by it are becoming more and more prominent, and it is difficult to completely eliminate them in a short time. [0003] So how to quickly purify the nitrite and heavy metals in the soil is an urgent problem we need to solve. Contents of the inven...
