Description

Cadmium pollutes farmland soil and restores and uses mixing arrangement

Technical Field

The utility model relates to a soil treatment technical field especially relates to a cadmium pollutes farmland soil and restores and uses mixing arrangement.

Background

Over the last two decades, the rapid development of industrial enterprises and the intensification of agricultural productivity have led to the introduction of cadmium into the soil environment through mining, smelting, and agriculture (e.g., pesticide and fertilizer applications). In the soil heavy metal pollution of China, cadmium is first in the standard exceeding rate of a point position of 7.0 percent. Cadmium is an unnecessary element for plant growth, has the characteristics of strong mobility, difficult elimination, high biocompatibility and the like in a soil ecosystem, once the cadmium enters an agricultural ecosystem, not only causes the quality reduction of agricultural environment, but also seriously influences the yield and safety of grains, and even directly threatens the health of human beings through a food chain. Therefore, the strengthening of the cadmium polluted farmland restoration and treatment has important significance for promoting the sustainable utilization of soil resources.

The existing cadmium pollution farmland governance approaches mainly comprise two approaches: firstly, the existing form of cadmium in soil is changed, so that the cadmium is fixed, and the migration and bioavailability of the cadmium in the environment are reduced; and the other is to remove cadmium from the soil, and respective physical, chemical and biological treatment methods are proposed around the two treatment ways. Among the methods for reducing cadmium in soil, the stabilization technology is widely concerned due to the characteristics of good effect, quick effect and simple operation. Stabilization is an immobilization process that converts high mobility cadmium to a solid or physico-chemically stable form through chemical interaction between the cadmium, soil particles and binder. This process reduces the mobility, bioavailability and bioavailability of cadmium, is less destructive and cost effective, and is a safe alternative to traditional remediation protocols (e.g., excavation, dumping, rinsing, etc.). The stabilization repair mechanism, such as surface adsorption, ion exchange, complex precipitation and the like, is different according to trace elements, and the key of the technology lies in selecting an economic, effective, green and environment-friendly repair agent.
