油田含油污水生化处理系统快速启动技术

摘要

Due to the effect of high salinity of oily wastewater and other biological inhibitors,it is difficult to improve the microbial enzyme activity and the microbial enzyme growth was inhibited.As a result,the startup time of biochemical system is long or even failure.For improving the toleration of microorganism to oilfield wastewater,the microbial enhancer in bilolgical contact oxidation was analyzed and screened.Meanwhile,the biofilm formation technology was studied in order to determinate the reasonable salinity increase speed,shorten the startup time of biochemical systems,and provide basic de-sign parameters for the field system start-up.%受油田含油污水高矿化度及其他生物抑制剂等条件的影响，微生物酶活性难以提高，抑制其生长，导致生化系统启动时间长甚至失败。因此对生物接触氧化法中微生物强化剂配方分析筛选，提高微生物对油田污水的耐受度，同时对挂膜工艺研究，确定合理的盐度增加速度，从而缩短生化系统启动时间，为现场系统启动提供基础设计参数。
