摘要
为提高对高含盐量石油发酵工业废水的处理效果,中试试验采用了AMBBR/SMBBR工艺,并与某石油发酵企业原厂的A/O工艺出水水质进行对比分析,结果表明,工厂现有的A/O工艺对污水中COD、NH_3-N、TP的平均去除率分别为96.4%、78.79%、96.8%,而AMBBR/SMBBR工艺对污水中COD、NH_3-N、TP的平均去除率可达到98.1%、96.3%、95.9%,其中NH_3-N的平均出水浓度为1.44 mg/L,达到国家的一级A标准,脱氮效果明显优于A/O工艺。AMBBR/SMBBR分别在进水流量增加1.5~2.0倍、NH_3-N浓度增加3~5倍的条件下,表现出较强的抗冲击负荷能力,出水氨氮浓度依然能达到一级A标准。AMBBR/SMBBR工艺可在原厂A/O工艺的基础上完成提标改造。
A combined pilot-scale AMBBR/SMBBR process is to improve the treatment effect of petroleum fermentation industrial wastewater with high salt content. The effluent quality is compared with that treated by the conventional A/O process. The results show that the average removal rate of COD,NH3-N and TP in the effluent treated by A/O process is 96. 4%,78. 79%,96. 8%,respectively. By contrast,the average removal rate of COD,NH3-N and TP in the effluent treated by AMBBR/SMBBR process is 98. 1%,96. 3% and 95. 9%,respectively. In particular,the average concentration of NH3-N in the effluent is 1. 44 mg/L,meeting national discharge standard. AMBBR/SMBBR is superior to A/O process on the removal of NH3-N. AMBBR/SMBBR also shows high resistance to impact loading capacity under the condition of increasing the inlet flow rate by 1. 5- 2. 0 times and increasing the concentration of NH3-N by 3- 5 times. The ammonia concentration in the effluent could reach first grade national standard. The AMBBR /SMBBR process facilitates the upgrading and reconstruction on the basis of A/O process of the original factory.
