On the one hand, metal is an important environmental element. If the heavy metal content in the soil exceeds the standard, a toxin will be released. This toxin will affect the soil and vegetation, accelerate the decay of the land, and affect the growth and development of crops. Quality also has a big impact. For example, the higher the heavy genus content, the higher the heavy metal content in the plant. When the concentration reaches a certain level, it will have an impact on photosynthesis, respiration, etc. On the other hand, there are environmental issues: for example, the soil contains heavy metals that cannot be completely removed. These pollutants, together with wind, water and other factors, act on the atmosphere and water, causing serious damage to the environment. For example, with the pollution of air and water sources, heavy metals will enter the bodies of animals and plants, form harmful chemical substances, and enter the human body through the food chain, posing a threat to the human body.
Therefore, in actual work, more scientific methods should be adopted to reduce pollution in this area, prevent the leakage and diffusion of pollutants, and gradually improve the entire environment, thereby laying a solid foundation for future agricultural production. Under the new situation, the heavy metal pollution in this area can be reduced through physical, chemical, plant and other ways.
At present, heavy metal pollution in soil presents complex characteristics, among which mercury pollution is the most frequent, followed by cadmium pollution, which brings great harm to agricultural production and people's life, and the treatment of heavy metal pollution has also attracted widespread attention from the society . Based on the specific situation, Desen Environment chose the corresponding technical solution and developed a soil washing equipment integrating physical, chemical and biological remediation - Desen washing car, which is considered to be an efficient and widely applicable 1. It is one of the equipments that can completely control soil heavy metal pollution. It has the advantages of short repair period and high repair efficiency, and has a good application prospect. It is the first mobile washing repair vehicle in my country. The whole equipment adopts the modular skid-mounted design, which greatly saves the installation time, and the transition is quick, and the floor space is small: it can be applied to soil washing and restoration of organic/heavy metal contaminated sites such as chemical industry, medicine, metallurgy, and steel, and can also It is suitable for project sites that require various types of physical washing, washing, and grading, such as ditch residue, river silt, shield mud, and mine restoration.
After years of "accumulation and steady progress", Desen car wash has achieved great success, and the operation effect of a certain case in Beijing is more perfect than expected. The appearance of the Desen washing car will greatly improve the comprehensive improvement effect of the soil and help residents live in a more comfortable and safer place.
