Desen's vision: How to solve the problem of chromium pollution remediation with high standard b
Desen Environment constantly explores efficient mobile soil remediation equipment in order to provide a new way for the development of soil remediation industry. Desen washing plant not only has a very good remediation effect on chromium-contaminated soil without secondary pollution, but also can save a lot of cost and time for soil remediation. It can be used in soil leaching remediation, mine remediation and cleaning, mine recovery, pollution remediation of mining wasteland, river silt treatme
According to incomplete statistics, there are currently 62 chromium slag dumps and legacy plots in China, and there are 36 salt plants, of which 10 are still in production. The main form of chromium in soil environment is trivalent chromium or hexavalent chromium compound, and the toxicity of chromium is related to its valence state. Trivalent chromium is harmless to human body, while hexavalent chromium is toxic. Hexavalent chromium is easily absorbed and accumulated in human body, and trivalent chromium and hexavalent chromium can be transformed into each other.
Soil leaching technology is a commonly used engineering method in soil remediation engineering. The leaching process can effectively remove the total concentration of pollutants in the soil, and the treatment speed is relatively fast, which has been widely used in the remediation and treatment of contaminated plots at home and abroad. The results show that citric acid and EDTA have good removal rates for hexavalent chromium in soil.
In recent years, Desen environment has been innovated and explored, and at the same time, it has been exploring efficient mobile soil remediation equipment to provide a new way for the development of soil remediation industry. The newly developed mobile soil washing equipment-Desen Washing Plant, not only has a very good remediation effect on chromium-contaminated soil without secondary pollution, but also can save a lot of cost and time for soil remediation. It can be used in soil leaching remediation, mine remediation and cleaning, mine recovery, pollution remediation of mining wasteland, river silt treatment, pipeline network dredging, drilling sludge treatment and other sites.
