Soil washing techniques are effective in reducing petroleum hydrocarbons in soil!
Soil is often contaminated during modern petroleum exploration, extraction, refining, processing and transportation. In these polluted soils, some of them have extremely high levels of petroleum pollutants, resulting in serious damage to soil structure and function. High concentration of petroleum c
Soil is often contaminated during modern petroleum exploration, extraction, refining, processing and transportation. In these polluted soils, some of them have extremely high levels of petroleum pollutants, resulting in serious damage to soil structure and function. High concentration of petroleum contaminated soil remediation is more difficult, on the one hand, the high concentration of petroleum pollutants toxicity, plants, microorganisms are difficult to survive, thus limiting the application of bioremediation; on the other hand, petroleum pollutants mostly belong to hydrophobic organic pollutants, can be present for a long time in the soil matrix, and the release of the slow release of a variety of remediation techniques to constrain the application of remediation technology.
At present, among the various methods for remediation of high concentration petroleum contaminated soil, washing and thermal desorption are the two most commonly used techniques. Among them, the washing technology is simple and easy to implement, can recover most of the dirty oil, can significantly reduce the content of petroleum hydrocarbons in the soil, and is a universal high concentration of petroleum contaminated soil remediation technology. The key to soil washing technology lies in the screening of cleaning agent and the optimization of cleaning process.
The oil sludge hot washing and grading treatment system developed by Desen Environment is an advanced oil sludge treatment technology. The system adopts hot washing technology, which can effectively separate the oil and solid particles in the oil sludge, thus reducing the volume and hazardousness of the waste. The core advantages of the system include:
Highly efficient oil sludge treatment: Through the action of high temperature and chemical agents, it is able to quickly separate the oil and solids in the oil sludge, dramatically improving the treatment efficiency.
Environmental friendliness: Wastewater and exhaust gases generated during the treatment process are strictly purified to meet environmental emission standards.
Resource Recovery: The oil recovered from the oil sludge can be reused, realizing the recycling of resources.
Safety: The system is easy to operate, safe and reliable, which reduces the safety risk during operation.
Desen oil sludge hot washing and grading treatment system can not only effectively treat oil contaminated soil and reduce environmental pollution, but also recover valuable resources and bring economic benefits to enterprises. In addition, the application of the system also helps to improve the level of environmental protection in the oil industry and promote sustainable development. In a word, with its high efficiency, environmental protection and safety, Desen oil sludge washing treatment equipment has become an ideal choice for treating oil-contaminated soil. With the increasingly stringent environmental protection requirements and the growing awareness of resource recovery, this technology of Desen Environmental will play a greater role in the future.
