摘要：研究了添加生化黄腐酸对活性污泥工艺处理废水的强化效果。在4个反应器中分别添加0、2、4和6mg/L浓度的生化黄腐酸,反应器采用分批连续运行方式,系统稳定后,考察添加生化黄腐酸对活性污泥工艺运行的影响。结果表明生化黄腐酸能加快废水中COD、氨氮和总磷的去除,促进微生物对难降解有机物的降解,并能降低出水中悬浮固体物的浓度,提高污泥的活性,达到改善活性污泥工艺运行的目的。
The impact of adding biochemical fulvic acid to SBR process was studied in the experiment. Four reactors with batch sequence operation were added biochemical fulvic acid with concentration of 0mg/L, 2mg/L, 4mg/L and 6mg/L respectively. The performance of operation were analyzed when the system of reactors run stability. Results showed that removal efficiency of CODcr and NH3-N can be accelerated, microorganism was activated to biodegrade recalcitrant organic matter, and concentration of SS in the effluent can be decreased. In the bench scale, the performance of SBR process can be enhanced by adding biochemical fulvic acid.
