The present invention belongs to the field of soil remediation technology and relates in particular to an apparatus for remediation of contaminated soils and a corresponding remediation method for soil remediation.

Technology in the background

Nearly 1/5 of China's existing arable land is contaminated to varying degrees, and contaminated soil will lead to a reduction in crop yields and even cause the pollutants in agricultural products to exceed the standard, thereby endangering human health. Soil is originally all kinds of waste natural protection and purification processing on site, soil acceptance of pollutants, does not mean that the soil that is polluted, only when the soil in the protection of all

Types of pollutants is too much, which and more than the self-cleaning power of the soil, so in hygiene and epidemiological harmful effects, only that the soil has been contaminated. There are many causes of soil contamination, such as:

Industrial sludge, agricultural waste, sewage irrigation, disposal of

Pollutants in the atmosphere and the extensive use of heavy metal-containing

Mineral fertilizers and pesticides.

Soil remediation involves the use of physical, chemical and biological

Methods to transfer, absorb, degrade and transform pollutants in the soil so that their concentrations are reduced to acceptable levels or to convert toxic and harmful pollutants into harmless substances. The technical principles of

Remediation of contaminated soils essentially includes: changing the form in which

pollutants are present in the soil or the way in which they are bound to the soil, thereby reducing their mobility in the environment and their bioavailability, and secondly, reducing the concentration of pollutants in the soil.

Nowadays, chemical methods are more commonly used for the remediation of contaminated soils, i.e. chemical remediation solutions are mixed with the soil to

To break down pollutants through chemical reactions; When using chemical

However, there is a problem with soil remediation equipment that the chemical

Substances and soil are mixed unevenly and there are no devices for the

Treatment of contaminated soils in batch mode, which ultimately leads to poor results, high remediation costs and low remediation efficiency.
