| 中文摘要 |
| 采用厌-好氧交替(AAA)工艺处理适当稀释或原浓度的油田废水,进水COD 360-950mg/L,COD去除率均保持在60%左右。经过厌氧UASB反应器处理后的废水,再经AAA工艺进行处理,在HRT 8-12h的条件下,其COD浓度能够从350mg/L降到160-240mg/L,COD去除率31%-48.5%.对于COD浓度为160-180mg/L的废水,采用好氧接触氧化法作为好氧二级处理,其出水COD去除率在50%-60%,出水COD浓度一般接近80mg/L左右。 |

| This paper reports the experimental treatment of petroleum wastewater from Liaohe River using a single alternation of anaerobic/aerobic(AAA)process,and the overall treatment system.The results shown that for the diluted or rural petroleum effluent of COD 360—950mg/L,more than 60% COD removal efficiency could be reached by AAA process.For the petroleum wastewater of COD 350mg/L pretreated by UASB reactor,AAA proccss could remove 31%—48.5% COD in the range of HRT 8—12h,i.e.the effluent COD 160—240mg/L.When the feed of COD 160—180mg/L was treated by contacted process as the secondary aerobic treatment unit,the effluent COD further decreased to about 80mg/L,COD removal efficiency 50%—60%. |
