Technical Field
The invention relates to the field of soil remediation, in particular to a bidirectional remediation method for heavy metal ion contaminated soil.
Background
The soil inorganic pollutants are relatively prominent in heavy metals, and the heavy metals are easy to accumulate and are converted into methyl compounds with higher toxicity because the heavy metals cannot be decomposed by soil microorganisms, and even some of the heavy metals are accumulated in a human body at harmful concentration through a food chain and seriously harm the health of the human body.
The heavy metal pollutants in soil mainly include mercury, cadmium, lead, copper, chromium, arsenic, nickel, iron, manganese, zinc, etc., although arsenic is not a heavy metal, it is usually discussed as being classified as a heavy metal because its behavior, source and harm are similar to those of heavy metals. As far as the needs for plants are concerned, the metallic elements can be classified into 2 types: the plant growth and development does not need elements, such as cadmium, mercury, lead and the like, which are obviously harmful to human health. Secondly, elements required by normal growth and development of plants have certain physiological functions to human bodies, such as copper, zinc and the like, but too much elements can cause pollution and hinder the growth and development of the plants.
Since the same metals have different forms in soil, and have different migration and transformation characteristics and different pollution properties, when the harm of heavy metals in soil is researched, attention is paid not only to the total content of the metals, but also to the content of various forms.
With the rapid development of industry and the wide use of pesticides and chemical fertilizers, the heavy metal pollution of soil is increasingly serious. Heavy metal pollution generally is soluble heavy metal pollution, namely the heavy metal exists with the form of ion, to heavy metal pollution in the soil, soluble heavy metal ion is generally in the moisture that exists in the soil more concentrated, among the prior art to heavy metal ion contaminated soil's restoration generally be with contaminated soil removal, spray the adsorbent or bury the built-in fitting underground, but the pertinence of first two kinds of modes is not strong, belong to indiscriminate restoration, lead to overall efficiency lower, last mode, usually only one-way adsorption effect, therefore need constantly retrieve and renew, lead to the restoration efficiency equally lower.
