摘要
微生物促进剂(VB591和BiNutrix-ww)可不断释放营养素,以保证微生物的健康生长,有助于加快微生物矿物化过程,促进有机污染物分解,达到水体净化的目的。在采集的油田废水中分别投加这两种微生物促进剂,与参照对比水样按相同条件进行了曝气处理。试验结果表明,微生物促进剂能使废水中COD和石油类的去除率大大提高,处理时间也大大缩短。
Microbiological agents (VB591 and BiNutrix-ww) can release neutrient continuously to improve the growing of microbiology and fasten the mineralization of microbiology and enhance the decomposition of organic contaminant and sewage purification. The two kinds of microbiological agents were respectively added into the produced-water samples collected from Dagang Oilfield. Compared with the referent water sample, under the same treatment conditions, the chemical oxygen demand and oil content in the produced-water samples added microbiological agents decreased greatly. The treatment time was also reduced.
