A novel soil restoring carpet and a method of restoring soil by utilizing the carpet

Abstract

A novel soil restoring carpet and a method of restoring soil by utilizing the carpet are disclosed. The soil restoring carpet comprises enteromorpha adsorption layers covered with hydrophilic fiber clothes and subjected to antiseptic treatment, protonation treatment, crosslinking treatment and hydrophilic treatment. A supporting fiber layer is disposed between the enteromorpha adsorption layers. The method includes steps of excavating a soil layer, horizontally paving the soil restoring carpet underground, covering with the soil layer, excavating the soil layer after crops are ripe and harvested with heavy metal pollutants in soil migranting to the soil restoring carpet and being adsorbed by the enteromorpha adsorption layers, taking the soil restoring carpet out, and performing landfill treatment. The enteromorpha adsorption layers adopt the enteromorpha as a raw material, are wide in source, low in cost, capable of periodic replacement and capable of effectively adsorbing heavy metals, organic pollutants and inorganic pollutants in the soil. Soil is restored and plantation of crops is not influenced at the same time. The enteromorpha is treated and waste resource reutilization is achieved at the same time.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, in particular to a novel soil remediation carpet and a method for soil remediation using the carpet. Background technique [0002] With the rapid development of economy, the discharge of "three wastes" in urban industry and domestic sewage is increasing day by day, the problem of agricultural environmental pollution caused by sewage irrigation is becoming more and more serious, and the problem of heavy metal pollution is particularly prominent. Heavy metals cannot be decomposed by soil microorganisms in the soil, have mobility and retention, can be bioaccumulated and become pollutants that accumulate in the soil, which not only affects the growth and development of crops, yield and quality, but also affects the growth and development of crops through the food chain. harm to human health. In addition to the abuse of chemical fertilizers and pesticides, incidents of heavy metal pollution ...

AI Technical Summary

Problems solved by technology

Pile up and landfill the Enteromorpha that has been fished out with great painstaking efforts, which not only wastes natural resources, but also damages the environment

[0007] Existing studies have shown that living Enteromorpha has a good ability to adsorb heavy metals, and dead cells have similar or even higher adsorption capacity than living cells. If Enteromorpha can be treated and applied to the treatment of heavy metal pollution in soil, it will have a great impact on waste resources. It is of great significance to the chemical utilization and soil remediation technology research. At present, there is no relevant report
