采用酸化-铁/碳内电解-ABR(厌氧折流板反应器)处理油页岩干馏废水,考察了最佳酸化条件；铁/碳内电解工艺中的铁碳比、pH值及反应时间等影响因素；ABR工艺最佳处理条件。结果表明：酸化隔油处理最优条件是将油页岩干馏废水pH值调为4.0,静沉24 h；铁/碳内电解最优条件：铁/碳质量比为5∶8,pH值为5.0,反应时间为60 min,静沉2 h；采用ABR处理铁/碳内电解出水,进水CODcr<2000 mg/L,水力停留时间为48 h,使得挥发酚的总去除率达到100%,矿物油总去除率达到99.8%, CODcr的总去除率可达97%。出水CODcr达到污水综合排放标准(GB8978-1996)三级排放标准,说明该技术具有可行性。

The combined process of acidification and ferric-carbon micro-electrolysis and Anaerobic baffled re-actor was used to pre-treat oil shale retort wastewater. The influence factors,such as optimum acidized condi-tion,ferrous-carbon ratio,pH value and reaction time were investigated;ABR process optimum processing con-ditions. The results showed:in the acidification process,the optimum oil shale retort wastewater acidized condi-tions were pH value 4. 0 and sediment 24h. In the ferric-carbon micro-electrolysis process,the treatment effect of ferric-carbon micro-electrolysis was the best with ferrous-carbon ratio 5 ∶ 8 , pH value 5 . 0 , reaction time 60min and sediment 2h. Processing the water from ferric-carbon micro-electrolysis in the ABR,the optimum conditions were CODcr<2000mg/L and HRT 48h,the removal rate of phenol was 100%,the removal rate of mineral oils was 99. 8%,the removal rate of CODcr was 97%. The CODcr fully reached the third grade stand-ard in Wastewater Integrated Discharge Standard(GB8978-1996). It showed that the processing technique was feasible.
