R2 of water content, oil content, total glucosinolate and protein content were estimated to be 99.64%, 98. 91%,82. 46% -98. 40% and 89. 32%,and RMSECV to be 0. 23,0. 39,2. 59-13. 50 and 0. 74,respectively.
The raw water was treated by use of conventional sendimentation and filtration processes and the quantity was 400L/d with the characteristic was summarized as suspension content of 8.2～15.5mg/L, oil content of 2.6～8.7mg/L and polymer content of 210～390mg/L, respectively.
The result shows that when the dosage of desulfirication flocculant HG-2 is 60~80 mg/L, the coflocculant PAM is 4~6 mg/L, by which the oil content in water before filtration ≤10 mg/L, content of suspended matter ≤5 mg/L and sulfide content ≤2mg/L are guaranteed.
The PP BCF of 2 650 dtex/150 f can be produced with extraordinary quality under the conditions of bulking temperature 145℃ , bulking pressure of 0. 5 MPa, feeding rate 1 400 m/min, denier per filament of 16-18 dtex, finish oil content about 1%.
The experimental results indicate that the removal rate of emulsified oil in the wastewater was about 85%～90% under temperature 25～40℃,solid-to-liquid ratio 1∶10 and HRT 6 h,oil content in wastewater 20～50 mg/L,and the oil content in treated water is below 5 mg/L.
The results showed that with pH value controlled at 3 ~ 4 and temperature at about 45℃ and with 0.001 mol/L potassium ferrate added to the low-concentration and PAM-containing wastewater from oil field, the degradation rate of PAM exceeded 90% 15 minutes after the reaction started, while the viscosity of the wastewater decreased to a level close to that of distilled water and the oil content in the effluent water reached the discharge standard.
As a result of the application of biotechnology, the water content in the production liquid from the trial site decreased, and the oil content increased.
The total yield, seed mass, and essential oil content increased significantly by 20 Gy dose of γ-irradiation as compared with the control samples.
An increase in the oil content leads to a change in the spherulite size; a decrease in the lamella size; and, accordingly, to a drop in the melting temperature of PP.
The mechanism of PP deformation gradually varies from the ductile to the quasi-brittle mode with a significant deterioration of mechanical characteristics of the material with an increase in the oil content.
It was found that the mechanism of oxidation of oil-extended PP depends on the oil content and the sample cooling mode.
