“…39 Complex use of acoustic impact with surfactants decreases the average size of solid particles in oil sludge; on the whole, this is useful to extract oil but heavily depends on the treatment time and can increase the probability of recombination of oil and solid matter with time. 40 Ultrasonic irradiation is a processing method that makes it possible to treat oil-containing sludges in a relatively short time. High efficiency of oil recovery and lack of secondary contamination notwithstanding, ultrasonic irradiation to recover oil from sludge is most frequently reported for laboratory systems and small volumes of treated media.…”

“…Combined use of ultrasound and thermochemical treatment made extraction of more than 99% of oil under ultrasonic treatment parameters of 28 kHz, 15 min, 400 W, and 60 °C possible; an increase of treatment time to 400 min did not further increase oil recovery .

The integrated effect on homogeneous and heterophase liquids that can be used for technological purposes has drawn the attention of researchers in various sciences. Cavitation impact on oil is among the efficient methods of intensifying chemical–technological, hydromechanical, and mass-exchange processes and the destruction of substances. This work reviews in detail and analyzes the mechanisms of impact and application of cavitation in various processes in the petroleum industry, including the refining processes, that are associated with crude oil and petroleum waste, such as reduction of viscosity, demulsification, desulfurization, and improvement of quality of heavy oil and petroleum refinery products, including oil sludge and waste oil-containing water.

“…The main methods of oily sludge treatment include incineration, pyrolysis, biodegradation, ultrasonic treatment, microemulsion, etc. [10][11][12][13][14] Due to the high equipment investment and operating cost, it is difficult to use pyrolysis for large-scale sludge disposal. The biodegradation method has the merit of low pollution and strong transferability, but a long time is needed for the complete conversion of harmful substances.…”

“…The exploitation of onshore petroleum has rapidly increased across the globe over the past few decades. Moreover, the leakage and misuse of production waste during the drilling, production, refining, and transportation of petroleum have caused serious and persistent contamination of soil oil producing regions, and the surrounding areas (Awari et al, 2020; Ergozhin et al, 2020; Z. Lin et al, 2021). Hence, how to efficiently remediate petroleum‐contaminated soil has become an issue worth exploring for the study of soil and environmental sciences.…”

In the present study, we assessed whether the nonadditive effects of mixed litter decomposition on soil biological and chemical properties, which was usually recognized in clean soils, could be used to enhance the efficiency of petroleum‐contaminated soil necrophytoremediation. In particular, six common plant species from the petroleum production region of Northern Shaanxi, China were collected, forming nine mixture types. The single and mixed litters were used to treat petroleum‐contaminated soil with a proportion of 45 g kg−1 at 25°C and a constant humidity for 150 days. The possible nonadditive effects on the efficiency of removing contaminants and recovering the damaged soil traits caused by the mixed litter addition were then investigated. The results indicate that monospecific litter treatments significantly increased the degradation rates of petroleum contaminants, the available N and P contents, and the catalase and dehydrogenase activities by 36%–74%, 28%–455%, and 8%–102%, respectively (p < 0.05). The mixed addition of the litters from Lespedeza davurica and Artemisia scoparia or those from Agropyron cristatum and Bromus inermis caused significant synergistic effects, enhancing the overall petroleum component removal, replenishing nutrients (particularly nitrogen) or stimulating enzymatic activities (especially for sucrase, phosphatase, catalase, and urease). The observed values of the corresponding indicators following mixed litter treatment were observed to significantly increase by 12%–18%, 23%–58%, and 9%–24% (p < 0.05), relative to their predicted values, which were calculated based on the observed values from the monospecific litter treatments and the proportion of the litter in the mixture. However, other litter combinations may weaken the remediation effects of the litter addition. In general, a high content of nutrients, primary metabolites (e.g., soluble sugars and amino acids), and the potential bio‐surfactants and co‐metabolized substrates (including terpenoids and flavonoids) of mixed litters enhanced the remediation efficiency of mixed litters. Notably, an increase in the chemical diversity of mixed litter may weaken its synergistic effects on the degradation of petroleum components and the simulation of soil polyphenol oxidase activity. Our results demonstrate that appropriate litter mixing combinations can effectively enhance the efficiency of necrophytoremediation, thus providing new approaches for the more convenient and economical remediation of petroleum‐contaminated soil.
