介绍一种能连续自动检测石油粘度的防爆型超声在线质量分析仪。具体讨论了仪器测量粘度的原理 ,仪表的防爆结构以及测量控制电路的组成和功能。该仪表已在数家炼油厂使用 ,效果良好。

Pseudomonas G31 cultured from the waste water of Shengli Oil Field can produce organic acid when growing and metabolizing in the oil culture G31 can degrade oil,what it products can lower the surface tension between water and oil,and emulsify oil to decline the viscosity and enhance the flow of oil

菌株G31是从胜利油田污水中分离到的 1株假单胞菌 (Pseudomonassp ) ,该菌株在石油液体培养基中能够生长发酵 ,产生有机酸和表面活性物质 ,可以应用于微生物三次采油。菌株G31可以降解和乳化石油、降低石油的粘度 ,其产物可以降低油水的界面张力 ,增加石油的流动性。室内岩心试验结果表明利用菌株G31发酵液进行驱油可使原油采收率提高 10 %以上。

This article overviews the study of the effect(factors) of crude oil bioremediation over last several years.The main effect(factors include:) 1.microbial species,which seem to have different degradation rate under varied circumstances and n-alkanes;2.physical and chemical properties of crude oil itself,which have an important effect on biodegradation,such as conglutination,boiling point,refractive index,ingredient and concentration of the oil;and 3.culture condition of microorganism,under which the degrading activity of microorganism will be affected by surfactant,light condition,sorbent,nutrition,co-metabolite,oxygen,temperature and salinity during the inoculation of selected or indigenous microorganisms.

本文概述了影响石油污染物生物降解修复处理的多种因素,对石油污染生物处理技术的发展进行了展望。其中主要影响因素包括:菌种的影响,菌种在不同的环境中和对不同碳链长度的碳氢化合物表现出不同的降解效率;石油物质本身物理化学特性的影响,如石油物质在水体或土壤中的浓度以及石油的粘度、沸点、折射率等特性;生存环境条件的影响,在接种入高效率的降解菌或利用土著微生物进行降解时,降解率受到生存环境中各种条件的影响,如表面活性剂、光照条件、吸附剂的利用、营养盐、共代谢底物、氧气、温度、盐度等。
