In the process of modern oil exploration, mining, refining, processing and transportation, soil pollution is becoming increasingly serious, especially the remediation of high-concentration oil-contaminated soil is difficult. Due to the high toxicity and hydrophobicity of oil pollutants, this type of soil makes it difficult for plants and microorganisms to survive, limiting the application of bioremediation technology. At the same time, the slow release rate of oil pollutants in the soil further exacerbates the complexity of the remediation work.

At present, the remediation technologies for high-concentration oil-contaminated soil mainly include washing and thermal desorption technologies. Among them, washing technology has become a universal remediation method because of its simple process, easy operation and effective recovery of contaminated oil. The key to this technology lies in the selection of cleaning agents and the optimization of processes. Through reasonable design, the content of petroleum hydrocarbons in the soil can be significantly reduced.

The sludge hot washing and grading treatment system developed by Desen Environment is an advanced sludge treatment technology that uses high temperature and chemical agents to separate oil and solid particles in sludge, thereby reducing the volume and harmfulness of waste. The core advantages of this system include high-efficiency processing capacity, environmental protection, resource recovery and operational safety. It 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 this system helps to improve the level of environmental protection in the oil industry and promote sustainable development.

With increasingly stringent environmental protection requirements and enhanced awareness of resource recycling, this technology of Desen Environment will play a greater role in the future. Through modular design and intelligent control system, Desen oil sludge washing system improves processing efficiency and environmental protection, and demonstrates its strong adaptability and stability in treating contaminated soil under complex geological conditions. For example, in the Ningxia Second Additive Factory project, the system successfully treated more than 100 tons of contaminated soil, and the remediation efficiency was significantly improved.

Desen oil sludge washing treatment equipment has become an ideal choice for treating oil-contaminated soil with its high efficiency, environmental protection and safety. In the future, with the continuous advancement of technology and the growth of market demand, this technology is expected to be widely used in more fields and contribute to the realization of green and low-carbon development.
