【摘要】：通过研究不同菌剂在目标废水中的生长曲线及COD的变化,筛选优势菌剂。结果显示,所购买的1号菌剂为优势耐盐菌剂,其最佳接种量(以体积分数计)为15%。将该菌剂按最佳接种量加入到反应器中,当进水COD为2 500 mg/L,盐度为8 000 mg/L时,对比对照组,COD处理效果明显;当盐度突然提高到10 000 mg/L时,出水COD变化稳定,待短暂适应新环境后,出水COD又趋于盐度提高前的稳定状态。
[Abstract]:By studying the growth curve of different bacterial agents in the target wastewater and the change of COD, the dominant bacteria agents were screened. The results showed that the best inoculation amount (in volume fraction) was 15. When the influent COD was 2 500 mg / L, the salinity was 8 000 mg/L, the treatment effect of the control group was obvious, and when the salinity suddenly increased to 10 000 mg/L, the effluent COD changed steadily. After adapting to the new environment briefly, the effluent COD tends to be stable before salinity is increased.
