摘要:

按照碳源优配原则优化分配进水流量,进行多段进水和进水比例可变条件下SBR脱氮效果研究。实验结果表明,采用SBR三段进水模式,当进水流量比为3:2:1时,系统脱氮效果最佳,此时NH4+-N、TN去除率分别为80.5%、67.4%。采用碳源优配原则对实际高氮印染废水处理工程进行提标改造,最终出水TN和NH4+-N均能达到《纺织染整工业水污染物排放标准》(GB 4278-2012)的间接排放标准。

Abstract:

According to the optimal distribution of carbon source, the effect of denitrification in an SBR was studied under the conditions of multi-stage water intake and variable water inlet ratio. The results showed that the denitrification effect of the system was the best when the SBR selected the three-stage water inflow mode and the optimal water inflow rate was 3:2:1 in the basin. Besides, the removal rate of NH4+-N and TN was 80.5% and 67.4%, respectively. The optimized carbon source distribution for SBR was conducted to upgrade the actual high-nitrogen printing and dyeing wastewater treatment project. The TN and NH4+-N of effluent met the indirect emission standard of Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry(GB 4278-2012).

Key words: printing and dyeing wastewater, denitrification, optimized carbon source, step-wise feeding
