| 中文摘要: |
| 分别以乙酸钠和丙酸钠作为有机碳源，利用序批式反应器系统对聚磷菌进行富集培养，通过高通量测序技术和化学分析，研究两种碳源对聚磷菌种类及除磷脱氮性能的影响。结果表明：稳定状态下，两者均取得良好的除磷率（＞94%），丙酸钠对除磷的促进作用优于乙酸钠，丙酸钠对脱氮的促进作用低于乙酸钠；在科和属的水平上，丙酸钠系统的聚磷菌丰度均高于乙酸钠系统。 |
| 英文摘要: |
| Taking sodium acetate and sodium propionate as organic carbon sources respectively, the impact of the two carbon sources on the structure of PAOs as well as nitrogen and phosphorus removal performance were studied based on PAOs enrichment culture by sequencing batch reactor(SBR)system, high throughput sequencing technology and chemical analysis. The results indicated that in stable condition, the two carbon sources both had high phosphorus removal rate(＞94%). Sodium propionate had better phosphorus removal effect but lower nitrogen removal effect than sodium acetate. The abundance of PAOs in sodium propionate system was higher than that in sodium acetate system at the level of family and genus. |
