Drained sludge of Daqing oilfield No.4 oil production plant was collected from bottoms of tanks, and the oil content was usually lower than 2%. In this paper, the contents of petroleum substances, total petroleum hydrocarbons (TPH) and animal and plant oil were investigated. Ultrasound-UV method was used to detect the oil content of oily sludge. Results showed that the best ultrasound time was 8 min and the best solid-liquid ratio for the extraction was about 1:20. The standard curve was constructed. The comparison between the ultrasound-UV method and the traditional method shows that the ultrasound-UV method is more suitable for the detection of oil content of oily sludge with lesser oil. Moreover, the methods of detecting sludge with lower oil content have been established.

Abstract In this work, oily compost leachate (OCL) generated during oily sludge composting was treated by UV/TiO2. OCL subsamples, gathered bi-weekly from the composting process, were thoroughly mixed and then filtered to reduce the solution turbidity. The effects of initial chemical oxygen demand (COD) concentration, UV type (A and C), pH (3, 7, and 11), reaction time (30, 60, 90, and 120 min), and TiO2 concentration (0.5, 1, and 2 g L−1) on the total petroleum hydrocarbons (TPH) and COD removal from OLC were examined. The results showed that the efficiency of the process improved with the increase in TiO2 concentration and reaction time and the decrease in pH and pollutant concentration. In the optimal conditions (UV-C, TiO2 concentration of 1 mg L−1, reaction time of 90 min, and pH of 3), 52.29% of TPH was removed. Moreover, 36.69 and 48.3% of TPH was reduced by UV-A/TiO2 and UV-C/TiO2, respectively in real conditions of OCL (pH = 6.3, COD = 1501. 24 mg L−1, and TPH = 170.12 mg L−1) during the 90 min reaction time. The study verified that UV/TiO2 has the potential to be applied to treat OCL.

The objective of this study was to prepare adsorbents from two kinds of oily sludge and evaluate their adsorption characteristics. The results showed that the optimum conditions of adsorbent made from JL sludge was using ZnCl2 as activator, the concentration of activatorwas 0.5mol/L, solid-liquid ratio was 1:2, pyrolysis temperature was 550°C, staying time was 2h. The optimum conditions of adsorbent made from LH sludge was pyrolysis directly. Pyrolysis temperature was 650°C, staying time was 2h. The surface morphologies of two adsorbents were relatively rough and had irregular porous structure mainly in mesoporous. The iodine adsorption values of two adsorbents can reach 451.22mg/g and 376.48mg/g and the oil removal rate of simulated wastewater can reach 91.47% and 92.28% respectively.

Background: A key challenge in the process of virus amplification is the need for a simple and convenient method for measuring virus titers. Objective: Real-time unlabeled cell analysis (RTCA) was used to establish a standard curve of correlation between half-cell index time (CIT50) and virus titer. At the same time, the virus titer from tunable resistance pulse detection (TRPS) technology was compared with the traditional median tissue culture infectious dose (TCID50) method to evaluate the feasibility and application value of the RTCA technique and TRPS technology. Methods: : Cell index (CI) values for L929 cells under different culture conditions were detected, and the appropriate initial cell inoculation density was screened. The half-cell index (CI50) values of reovirus infected L929 cells with TCID50 titers were analyzed by RTCA, the CI50-TCID50 standard curve was created, and a regression equation was developed. RTCA, TCID50, and TRPS methods were used to detect the reovirus titer obtained by the amplification, and the sensitivity and feasibility of the CIT50-TCID50 standard curve method were analyzed. The virus titer was detected by TRPS technology and the TCID50 method. Results: L929 cells were best propagated at an initial density of 6 × 103 cells/well. After infecting L929 cells with different titers of reference reovirus, the linear correlation of CIT50 and TCID50 was y = -2.1806x + 71.023 (R2 = 0.9742). The titer resulting from the RTCA assay was 7×109.6821 pfu/mL, from the TRPS assay was 4.52×1010 pfu/mL, and from the TCID50 assay was 7×109.467 pfu/mL. Conclusion: The CIT50-TCID50 standard curve method established by the RTCA technique can be used to quantitatively detect reovirus titer with L929 cells. Compared with the TCID50 method, it takes a relatively short time and has high sensitivity and accuracy. The TRPS technology requires even less time to quantify the virus, but its precision is lower than that of the TCID50 method and RTCA technology. This study provides new technical methods for assessing the virulence of infectious live reovirus particles. Lay Summary: After amplification of the virus, we need to detect the virus titers (the virulence of the virus). The traditional method is to use the virus to infect cells, and then the virus titers can be calculated by 50% of the cells infected. However, this traditional method is time consuming. The ways of RTCA (a real-time cell analysis technique) and TRPS (a nano-bioparticle analysis technique) help us to detect viral titers. The consistency of these three methods determines their feasibility and accuracy. If they are feasible, then these two simple technologies will provide new ideas for detecting viral titers.
