在炼厂污水处理过程中,生化系统活性污泥曝气池中产生泡沫现象是一种常见问题,主要是由于放线菌和丝状菌菌属的异样生长所造成。通过理论与实践探索,发现污水温度、pH值、溶解氧、污泥停留时间是影响泡沫产生的重要因素。泡沫的产生影响水处理的日常操作、装置运行、出水水质等,其处理方法有物理法、投加化学药剂、生物控制等,其中生物控制法是最优方法。 In the process of refinery wastewater treatment, the bubble phenomenon in the activated sludge aeration tank of biochemical systems is a common problem mainly due to the abnormal growth of actinomycetes and filamentous bacteria. Through theoretical and practical exploration, it is found that the temperature, pH value, dissolved oxygen and sludge residence time are the important factors that affect the foam production. The production of foam affects the daily operation of water treatment, plant operation, water quality and so on, and its treatment methods are physical method, dosing chemical agent and biological control, among which the biological control method is the best method.
