| Abstract: | The improvement of biodegradability for difficultly biodegradable oilfield produced water by hydrolysis and acidification process and the organic removal effect were discussed in this paper.The results demonstrated that with biomass 25 000 mg/L and HRT 12 h,oil con- tained in effluent was decreased below 10 mg/L and volatile hydroxybenzene was not detecta- ble,the oilfield produced water biodegradability was improved greatly and the rising BOD_5/ COD was 17%,which offered good substrate for post aerobic treatment.The process had strong capacity to withstand poisonous substances and shock loadings,and the effluent was stable. |
