[0002] In engineering fields such as oilfields that require filtration processes, various filter tanks are widely used as common equipment for deep sewage treatment. After being used for a certain period of time, the filtering sand material will have its filtering performance decreased or even blocked due to the adhesion and pollution of impurities such as waste oil and sludge, resulting in the loss of filtering performance. If the used filtering sand material is directly discarded, it will pollute the environment, and the cost of replacing new filtering sand material is relatively high. Therefore, the problem of reusing the filtering sand material has attracted much attention in the industry, and the cleaning process of the filtering sand material is the core technical point of reuse.
