Background
With the rapid development of industrial and agricultural production and the continuous acceleration of urbanization process, pollutants such as heavy metals, organic matters and the like are increasingly accumulated or biologically enriched in soil. Due to the irreversibility, latency and concealment of soil pollution, the surrounding environment is increasingly burdened and disastrous results may be caused. Therefore, the development of remediation studies for contaminated soil is an important issue in the current soil research.
Currently, soil remediation is a technical measure for restoring normal functions of contaminated soil. In the soil remediation industry, the existing soil remediation technologies can reach more than one hundred, and the common technologies also have more than ten, which can be roughly divided into three methods, namely physical, chemical and biological methods. In the soil remediation process, a remediation agent is often used for remediation at present.
However, when the existing soil remediation agent is prepared, chemical agents are mostly adopted, the chemical agents mostly cause secondary damage to soil, the remediation effect is poor, and for the remediation of some saline-alkali lands, the traditional soil remediation agent can only remove heavy metals, and the removal effect on the salt content of the saline-alkali lands is not great.
Accordingly, there is a need for improvements in the art. In the aspect of crops, the reutilization of straws becomes a research hotspot, for example, the Chinese patent application No. 202011299856.5 discloses a soil remediation agent prepared from crop straws and biochar.
