due to the rapid economic development and rapid urban expansion, the original urban suburban residential development and commercial development are extremely numerous. the former suburbs, which have more chemical plant areas, now need to be relocated and reused. however, due to the fact that in the process of production and operation of abandoned factories, the ground soil will be organically polluted to varying degrees, coupled with the hidden nature of soil pollution, the pollution determination is more complicated, resulting in further improvement of the difficulty of soil pollution control. finding effective soil remediation methods can fundamentally solve soil pollution. the traditional remediation technology of polluted soil is not mature, and it is generally adopted to replace the contaminated soil, dig out the polluted soil, and replace it with clean soil. in recent years, with the rapid development of science and technology, thermal desorption technology of polluted soil has been gradually applied.
Soil thermal desorption technology is mainly used in volatile/semi-volatile organic pollution soil remediation. For thermal desorption technology, the working principle is to continuously improve the volatility of pollutants through thermal energy, continuously separate pollutants from polluted soil and sediments, and concentrate on treating these pollutants. Soil thermal desorption technology compared with the past traditional treatment technology, the advantages are very significant, can be flexible mobile equipment, and can be widely used in the treatment of pollutants, and the remediated soil can be recycled, especially in the treatment of PCBs chlorine-containing organic compounds, more suitable for the application of thermal desorption technology, can effectively avoid the formation of two umying. In terms of performance, thermal desorption technology has shown significant advantages, and it is widely used in soil remediation in Europe and the United States today, and the achievements in organic pollution soil remediation are also very significant.
since 2010, desen environment has carried out localization of remediation technology research and development, promoted the integration of production, education and research, and newly developed a soil thermal desorption equipment. the main advantages are: the treatment process can meet strict environmental standards; wide range of applications, capable of handling all organic and partially inorganic matter; recycling of organic pollutants to achieve waste into treasure; strong operating efficiency, can be continuous operation 24 hours a day, the annual utilization rate of 85%; the soil dispersion capacity is improved, and the trend of soil agglomeration is reduced, which ensures the smoothness of the feed system and the thermal desorption effect of pollutants; can achieve efficient heat and mass transfer, high energy utilization efficiency; the thermal desorption system is equipped with an efficient and reliable exhaust gas treatment system to ensure that the exhaust gas meets the standard emissions; the modular, integrated and intelligent design of the thermal desorption system increases the compactness of the equipment and occupies a small footprint. for more information, please feel free to contact us.
