Description

Heavy metal contaminated soil remediation machine and using method thereof

Technical Field

The invention relates to the technical field of heavy metal contaminated soil remediation, in particular to a heavy metal contaminated soil remediation machine and a using method thereof.

Background

Heavy metal contamination refers to environmental contamination caused by heavy metals or compounds thereof. Mainly caused by human factors such as mining, waste gas discharge, sewage irrigation, use of products with heavy metals exceeding standards and the like.

The inorganic pollutants in the soil are relatively outstanding in heavy metal, and the heavy metal is easy to accumulate because the heavy metal cannot be decomposed by soil microorganisms and is converted into methyl compounds with higher toxicity, and even some methyl compounds are accumulated in a human body at harmful concentration through a food chain, so that the human health is seriously harmed.

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.

Heavy metal elements in soil mainly have two ways of natural sources and artificial interference input. Among natural factors, the matrix and the process of soil formation have great influence on the heavy metal content of soil. Among various human factors, the proportion of heavy metal pollution of soil caused by industrial, agricultural and traffic sources is high.

The fertilizer is not easy to be leached and dissolved with water in soil and can not be decomposed by soil microorganisms; on the contrary, organisms can enrich heavy metals, the heavy metals are often gradually accumulated in the soil environment, even some heavy metal elements can be converted into methyl compounds with higher toxicity in the soil, and the methyl compounds can be accumulated in human bodies at harmful concentration through food chains, so that the human health is seriously harmed. Compared with the pollution of water environment, the pollution of heavy metal to the soil environment is more difficult to treat and has more pollution hazard.

The main approaches for treating the heavy metal pollution of soil are two types: firstly, the existing form of heavy metal in soil is changed to be fixed, and the mobility and the bioavailability of the heavy metal in the environment are reduced; secondly, removing heavy metals from the soil. Around these two approaches to remediation, separate physical, chemical and biological methods of remediation have been proposed.

According to the above description, at present, for heavy metal contaminated soil remediation, the mode of adopting chemical agents and applying the chemical agents in soil is common, and the specific mode is that the contaminated soil and the agents are directly placed in the stirring tank which is arranged by adopting the stirring device, and the contaminated soil and the agents are uniformly mixed in a stirring mode.

However, the existing heavy metal contaminated soil remediation has some problems, when materials are added, the materials are added at one time or are added for multiple times, the materials have larger load on a stirring assembly, better mixing uniformity can be realized, and long-time stirring is needed; the latter requires manual operation for many times, which is relatively troublesome; simultaneously, the stirring subassembly can also throw away the material at the during operation, leads to the follow-up and stirring subassembly of material no longer to contact, leads to stirring effect not good.

Therefore, the inventor designs a heavy metal contaminated soil remediation machine and a using method thereof, and solves the problems.
