Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery, in particular to soil remediation equipment, in particular to a soil remediation composite stirring type soil changing device. Background Art
[0002] With the continuous advancement of urbanization, there are certain pollutants in the existing urban surface soil, which leads to certain risk factors when planting landscape plants or crops in the future. Therefore, in order to better meet the needs of plant planting and provide a safe environment for crop growth, the surface soil is sometimes repaired according to the planting characteristics of the plants and the degree of soil pollution.
[0003] Soil remediation is a technical measure to restore contaminated soil to its normal function. Literature review reveals that over one hundred soil remediation technologies exist today, including chemical leaching, incineration, composting, microbial degradation, and chemical leaching. Essentially, these technologies can be broadly categorized into three main categories: physical, chemical, and biological. These technologies decompose, degrade, neutralize, or alter soil contaminants, including adverse physical and chemical properties and pH. Traditional soil remediation involves mixing excavated soil with soil remediation additives such as solid iron powder, charcoal, and lime, or other active remediation solutions or bacterial cultures. Bioremediation, such as Vancolin, primarily uses water-based, biodegradable, mixed surfactants for cleaning and treating oil, salt, and paraffin-contaminated soils, as well as other degreasing cleaning products. Currently, soil remediation for landscape and agricultural purposes primarily relies on bioremediation methods such as phytoremediation, in situ or ex situ bioremediation, or chemical remediation methods such as chemical leaching, chemical oxidation, or solvent extraction. These techniques often require the injection or mixing of various substances into the soil to be remediated. Occasionally, more costly soil replacement methods are employed for short-term results, but these contaminated soils still require additional treatment, which will not be discussed here.
[0004] Most of the previous contaminated soil remediation devices achieve remediation through methods such as collecting the soil first, then reacting the agent and the contaminated soil in a stirring device to remediate the contaminated soil, and then refilling the remediated soil into the original place. This is not very efficient. Therefore, an improved technology is urgently needed to solve the above problems existing in the existing technology. Utility Model Content
