Bacterium Control Technology of Water Injection System in Zhongyuan Oilfield

An economical and effective bacterial growth controlling process was developed.The results showed that the advanced oxidant could kill all bacteria in sewage when the oxidant concentration was 8 mg/L.When pH increaed,bacterial growth would be inhibited,and SRB could be controled completly when pH was 8.0.The cationic fungicide in water purification had good bactericidal effect,and was dominating in the whole control of the bacteria.
