| Abstract: | Biological treatment is the most important process to coal gasification wastewater. Comparing the effectiveness of treatment on contaminants in various biochemical environment, it could be found that pollutants in coal gasification wastewater have different characters in the process of aerobic and anaerobic degradation. Effectiveness of aerobic process on the phenolics removal is higher for high strength actual wastewater than that of anaerobic process. The anaerobic process is easily inhibited, but can enhance the effect of aerobic treatment through changing the molecular structure of pollutants in the wastewater. From this result, an improved biological process is put forward for coal gasification wastewater treatment. |
