The salinity of produced water which is from Guanghua station in Jianghan Oilfield is very high, suspended matter, median grain diameter and iron ions in the effluent went beyond the standard greatly, and water qualification rate is low. Through the process adjustment, adding adjustable storage tank of 1000 m³ and reverse demulsifier AK-2 developed by Yangtze University in anterior segment, then the content of suspended matter ≤4mg/L, oil content ≤2mg/L in the effluent, the water quality achieved the standards; meanwhile, the inverting demulsification + Fenton reaction was introduced into flocculating sedimentation stage, which contributes to the removal of iron ions. The operation of adjustment process is stable and reliable in Guanghua station, which greatly improves the water quality. [ABSTRACT FROM AUTHOR]

BACKGROUND: Some studies have found a certain relationship between the distribution of traditional Chinese medicine syndrome types and the morphological differences in femoral head necrosis. OBJECTIVE: To observe the morphological differences of hip joints of different types of traditional Chinese medicine syndromes with femoral head necrosis through 3D graphics, and to evaluate the efficacy of standardized and comprehensive non-surgical hip preservation for femoral head necrosis. METHODS: From December 2016 to February 2017, 73 femoral head necrosis patients (1 08 hips) treated with non-surgical hip preservation in the First Affiliated Hospital of Guangzhou University of Chinese Medicine were enrolled in this study. According to the syndrome type of traditional Chinese medicine, the patients were divided into the kidney deficiency and blood stasis group (47 hips), the accretion group (30 hips) and the Qi stagnation and blood stasis group (31 hips). X-ray films and CT spiral scans of both hips were taken to measure the central hip angle, Sharp angle, upper and lower acetabular diameter, anteroposterior diameter, and acetabularity depth, acetabular abduction angle, and acetabular anteversion angle. Totally 88 cases (131 hips) of femoral head necrosis treated with standardized comprehensive hip preservation from December 2016 to February 2017 in the First Affiliated Hospital of Guangzhou University of Chinese Medicine underwent traditional Chinese medicine, physical therapy, and functional exercise. The clinical function of hips was diagnosed by visual analogue scale and Harris scores, and the necrosis in the treabnent area was evaluated by X-ray films. This study was approved by the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine, approval No. Y[20191118. RESULTS AND CONCLUSION: (1) X-ray films showed significant differences in Sharp angle and central edge angle among the three groups (P < 0.01 ). Among them, the sharp angle was largest; the central edge angle was smallest in the kidney deficiency and blood stasis group. The Sharp angle was smallest and the central edge angle was largest in the Qi stagnation and blood stasis group. (2) CT spiral scan showed that there was a difference in abduction angle between the three groups (P < 0.001 ), of which the kidney deficiency and blood stasis group was largest. Acetabularity depth was smaller in the kidney deficiency and blood stasis group than in the Qi stagnation and blood stasis group (P < 0.05). There was no significant difference in the upper and lower acetabular diameters, anteroposterior diameters, and acetabular anteversion angles of the three groups. (3) After 2 years of comprehensive hip-sparing treatment, 88 patients had significantly improved pain and hip function. Imaging results showed an improvement of 89 hips and 21 unchanged hips, with an improvement rate of 67.9%. (4) The results showed that there was a difference in hip joint morphology between different syndrome types. The development of the acetabulum of kidney deficiency and blood stasis type was poorer than that of Qi stagnation and blood stasis type and accretion type. Standardized and comprehensive non-surgical hip-sparing treatment of femoral head necrosis in the early and middle stages can significantly improve the symptoms of patients in the short tenn.

In order to solve the problem of oily sludge treatment of Jianghan oilfield,this article evaluated the best ginseng of coal, corrosion resistance, heat of combustion and gas composition, based on the components analysis of oily sludge. The results indicated that Jianghan oilfield oily sludge has the characteristics of high water content, high salt content and low oil content. The oily sludge works best when the content of coal is 60%. Oily sludge burning showed low calorific value, high corrosion rate, burning gas SO2 exceeding badly, low pH of distilled water absorption liquid, easy to cause perforation equipment and acid rain. Therefore, it is unfavorable to use incineration technology for Jianghan oilfield oily sludge because of high water content, high salt content, high corrosion, low oil content, low combustion heat value, and the rain, moist air of Jianghan district and so on.
