Three kinds of media are the same diameter oil and water dynamic wetting process from Figure 3a shows, in terms of water use magnetite filter, magnetite wettability is clearly better than the ceramic sand; Walnut Shell poor wettability. 3b shows three kinds of oil filter can be wet, magnetite best, followed by walnut shells, and the ceramic sand is the worst. In addition, Figure 3 also shows that the wetting process linear segments mainly located up within 20 s, therefore, the time when the wettability comparison with W ashbum dynamic method of water treatment media, should use 0 ~ 20 s strike in paragraph .3 kind wetting rate for water and filter respectively oil wetting rate curve magnetite media application, thereby utilizing W ashbum equation and the amphiphilic ratio (LH R) concept can be drawn from three kinds of media lipophilic tendencies quality magnetite media, which wetting rate and results in Table 3 Table 3 shows the magnetite water wetting rate greater than ceramic sand, walnut shells and water wetting the minimum rate; for oil, the magnetite wetting The maximum rate, while the smallest ceramic sand. calculated walnut shell, magnetite and ceramic sand LH R value of the order of 76 41, L 057 and 08 769 (Table 3), indicating walnut shell lipophilic much better than magnetite and ceramic sand, and magnetite better than ceramic sand. Because the same experiment, the filter size, fill factor similar bed volume, and therefore three kinds of filter for water and oil wetting rate and LH R the difference value is clearly attributed to the different structure of the filter surface. to the east of a sewage treatment plant reinjection regular monitoring of the water quality test results show that the processing station runoff salinity 185 400 mg / L, total iron content 29.9 mg / L, a high salinity, high iron sewage. After deep bed filtration, the average oil content of 2.97 mg / L, the average concentration of suspended solids of 8.29 mg / L; by dual filter, the average oil content of 1.24 mg / L, the average concentration of suspended solids of 4.76 mg / L, The average particle size of median 6.57} m. Suspended solids, exceeding the median particle size, did not meet corporate standards Tarim Oilfield "water quality indicators and analysis methods (C} / SY TZ 0086-2002)" WQOs requirements (ie prisoners Marina Tan Chau Weng amount Rui Guang Kui 1.0 mg / L, record the amount of core 1.0 mg / L, the median particle size core 1.0} m). On the east by a water reinjection sewage treatment plant site investigation, water quality analysis found the following problems magnetite media, the existing process: (1> The station effluent suspended solids content, particle size in value is exceeded, filtered to remove a small section poor suspended solids. (2> Double filter media filter gradation unreasonable, poor filtering effect. The station uses walnut shells, Emery dual media filter gradation unreasonable, is 0.8 a 1.2 mm , gradient filter layer can not be achieved, the effect is not sufficiently exhibited double rejection filter, so the ability to remove fine suspended solids decrease. magnetite media image _ German source water (certified) _ Xi'an magnetite filter German source material provided by the Henan Water Treatment Co., Ltd.
