Fly ash contains heavy metals. How to remediate contaminated soil?
As an emission from coal-fired power plants, fly ash is the largest source of solid waste pollution in China. Its accumulation not only occupies a large amount of land resources, but also causes serious environmental pollution to surrounding soil, water and air. Fly ash contains a certain amount of
As an emission from coal-fired power plants, fly ash is the largest source of solid waste pollution in China. Its accumulation not only occupies a large amount of land resources, but also causes serious environmental pollution to surrounding soil, water and air. Fly ash contains a certain amount of heavy metals, such as lead (Pb), cadmium (Cd), chromium (Cr), etc. These heavy metals accumulate in the soil for a long time and may enter the human body through the food chain, posing potential threats to human health.
In the process of treating fly ash contaminated soil, using Desen soil washing equipment to remediate soil containing heavy metals has significant advantages. Here is a detailed analysis of this advantage:
Efficient processing capacity: The maximum processing capacity of Desen soil washing equipment can reach 100t/h, showing strong processing capacity. The reduction of contaminated soil after treatment can reach more than 90%, which can quickly and effectively solve the problem of soil pollution.
Precise eluent ratio: The equipment can accurately control the eluent ratio to ensure that pollutants in the soil can be effectively removed without causing secondary pollution to groundwater. Adopting a modular design and flexible layout, it can be quickly adjusted and deployed according to different working scenarios. The transition is fast and convenient, and the installation is fast and efficient, which greatly shortens the project cycle. Intelligent operation, using PLC intelligent control system, stable operation, 24-hour continuous operation, improving operating efficiency and reducing manual work intensity.
Desen Environment provides customers with high-quality service guarantees, including on-site guidance on equipment installation, debugging, and operation to ensure that the equipment can be put into use smoothly. Assist customers in running their equipment for one month free of charge, provide 7×24 hours service, rush to the site within 48 hours to deal with problems, and respond to customer needs in a timely manner.
The equipment can recycle part of the clean water during the washing process, reducing water consumption and emissions. Use low-noise, low-energy-consumption motors and reducers to save electricity and reduce carbon emissions. Desen soil washing equipment is suitable for the repair of various soil pollution problems such as chemical industry, medicine, metallurgy, organic/heavy metal contaminated sites, etc. It has been successfully used in many domestic and foreign contaminated site remediation projects such as the Qinghai arsenic pollution project, the Shanghai Putuo chemical site remediation project, and the Changsha chromium salt plant remediation project.
In summary, Desen soil washing equipment has demonstrated the advantages of high efficiency, precision, flexibility, environmental protection and wide application in the process of contaminated soil treatment, especially for soil remediation containing heavy metals. These advantages make Desen soil washing equipment an important tool in the environmental engineering remediation industry, contributing to environmental protection and sustainable development in my country and even the world.
