The influence of organic loading rate (OLR) on the performance of hydrolytic acidification process for treating 2-butenal manufacture wastewater was comprehensively studied, while its impact on microbial community was thoroughly investigated. The results demonstrated that over 21.0% of the average COD removal rate was observed in the range of OLR from 0.52 to 3.98g COD/L·d, whereas it reduced to 15.3% with increasing OLR to 6.09g COD/L·d. The acidification degree dramatically decreased from 17.1% to 4.7% when OLR increased from 3.98 to 6.09g COD/L·d. In addition, the removal rates of three kinds of typical matters were less than 65% at the OLR 6.09g COD/L·d. Illumina MiSeq sequencing revealed that Proteobacteria, Chloroflexi, Firmicutes, and Bacteroidetes were dominant phyla at different OLRs. Finally, multivariate analysis suggested that the genera Longilinea and T78 had a positive correlation with the degradation of three kinds of typical matters and COD removal rates.
研究了有机负荷率（OLR）对处理 2-丁烯醛生产废水的水解酸化工艺性能的影响，同时深入研究了其对微生物群落的影响。结果表明，在 OLR 为 0.52 至 3.98g COD/L·d 的范围内，平均 COD 去除率超过 21.0%，而当 OLR 增加到 6.09g COD/L·d 时，降低至 15.3%。当 OLR 从 3.98 增加到 6.09g COD/L·d 时，酸化程度从 17.1%急剧下降到 4.7%。此外，在 OLR 为 6.09g COD/L·d 时，三种典型物质的去除率均低于 65%。Illumina MiSeq 测序表明，在不同的 OLR 下，变形菌门、绿弯菌门、厚壁菌门和拟杆菌门是主要的菌门。最后，多元分析表明，属 Longilinea 和 T78 与三种典型物质的降解和 COD 去除率呈正相关。
