The soil pollution of chromium slag dump is mainly manifested in excessive heavy metal chromium, among which hexavalent chromium has become the main concern due to its high toxicity and strong mobility. The distribution of chromium pollutants in the soil is uneven, usually the most serious in the chromium slag storage area and its surrounding areas, and the degree of pollution shows a trend of first increasing and then decreasing with increasing depth.
Chromium in the soil mainly exists in the form of residue, but the exchangeable state and carbonate-bound state also account for a certain proportion, which indicates that there is a certain potential risk. Hexavalent chromium has a strong migration ability and poses a great threat to the environment and human health. The soil in the chromium slag dump is not only polluted by chromium, but also may be contaminated by other heavy metals or organic pollutants. These pollutants may interact with each other, affecting their environmental behavior and ecological risks.
The entire process of Desen mobile leaching remediation excavates, screens and grades the chromium slag contaminated soil to remove large impurities and stones for subsequent treatment. Adjust the soil moisture to ensure effective contact between the eluent and the pollutant. The prepared eluent is evenly injected or sprayed into the contaminated soil through the Desen mobile leaching equipment to achieve full reaction with the chromium pollutants. The leaching effect is enhanced by mechanical stirring and other means to promote the stripping of chromium pollutants from the surface of soil particles.
The solid-liquid separation system of the equipment is used to separate the treated soil from the waste liquid containing chromium, and the clean soil can be used for backfilling or other purposes. The collected waste liquid is treated by the water treatment system to remove the chromium ions in it, and the water resources are recycled for leaching and recycling to reduce environmental pollution.
Desen soil leaching equipment can not only effectively remove heavy metals, but also be regarded by customers as an ideal soil remediation equipment. The equipment has been operating normally in the hexavalent chromium contaminated site in Hunan, with a processing capacity of up to 100t/h. This leaching equipment is designed to be mobile, with fast installation and convenient transfer, which can greatly shorten the repair time and save costs; with the help of 5G smart modules, it can be remotely operated and monitored at all times.
Desen mobile leaching and remediation equipment has demonstrated its advantages of high efficiency, flexibility, environmental protection and economy in the treatment of chromium slag contaminated soil, and has provided effective technical support for solving the problem of soil pollution in chromium slag yards.
