本研究将取自石油设备中的细菌与注水处理常用的15种化学剂一起进行生长试验。该试验是采用好氧和厌氧条件下生长的混合菌群以及厌氧条件下生长的SRB纯菌种进行的。研究结果表明,有3种化学剂可作为细菌生长的氮(N)源,有1种可作为磷(P)源,有7种可作为碳(C)源。这些化学剂包括一种除氧剂、三种防垢剂、一种聚合电解质、一种表面活性剂、二种消泡剂和二种螫合剂。剩余的六种化学荆在试验条件下不促进细菌生长。其中五种(包括三种杀菌剂)含有在油田条件下可被细菌利用的营养物。根据本研究,可以断定水处理添加剂中细菌的生长潜力是存在的。因此,在选择化学剂之前应进行调查。
This study will be taken from petroleum equipment bacteria and water treatment commonly used 15 kinds of chemicals together for growth experiments. The experiment was conducted using mixed bacteria grown aerobically and anaerobically as well as pure SRB grown under anaerobic conditions. The results show that there are three kinds of chemicals can be used as nitrogen (N) sources for bacterial growth, one as a source of phosphorus (P) and seven as a source of carbon (C). These chemicals include an oxygen scavenger, three scale inhibitors, a polyelectrolyte, a surfactant, two defoamers and two chelating agents. The remaining six chemicals do not promote bacterial growth under experimental conditions. Five of these, including the three fungicides, contain nutrients that can be used by bacteria under oilfield conditions. Based on this study, it can be concluded that there is a potential for bacterial growth in water treatment additives. Therefore, before selecting chemicals should be investigated.
