| 中文摘要: |
| 从含酚废水处理池污泥中驯化得到苯酚降解菌——假丝酵母菌FD-1，通过试验考察FD-1对高浓度苯酚废水的降解效果，以及十二烷基磺酸钠（SDS）对高浓度苯酚废水中FD-1菌株生长的影响。试验表明，假丝酵母菌FD-1对苯酚的最大降解质量浓度为1 500 mg/L，降解时间为30 h。当苯酚质量浓度不超过1 000 mg/L时，添加适量的SDS可以显著提高苯酚降解速率，进而缩短苯酚降解时间，SDS的最佳投加量为100 mg/L，超过150 mg/L时FD-1生长受到抑制。 |
| 英文摘要: |
| FD-1, a phenol degrading bacterium acclimated from the sludge of a phenol containing wastewater treatment pool. The effect of FD-1 on the degradation of high concentration phenol wastewater and the effect of SDS on the growth of FD-1 strain in high concentration phenol wastewater were investigated by experiments. The results showed that the maximum degradation concentration was 1 500 mg/L by FD-1 strain, and the degradation time was 30 h. SDS can significantly improve the rate of phenol degradation when the phenol concentration no more than 1 000 mg/L, which can shorten the time of phenol degradation. The best dosage of SDS was 100 mg/L.The growth of FD-1 was inhibited when the SDS concentration reached 150 mg/L. |
