Experimental research on oil shale retort wastewater treatment by integrated biochemical process

In view of the characteristics of oil shale retort wastewater, a biochemical process combining anaerobic, anoxic, aerobic process and sedimentation was chosen for its treatment, and the pilot test was carried out. The effect of the said process on oil shale retort wastewater treatment was investigated with its technical fea- sibility discussed at the same time. The running condition of the system showed that, using integrated biochemi- cal process to treat oil shale retort wastewater could get a stable and high-efficient treatment effect, and the re- moval effect of CODc, NH3-N and oil was also good, which provided technical support for industrialized treat- ment of oil shale retort wastewater.
