摘　　要：研究通过建立SBR反应器来探究磺胺甲恶唑对生物除磷性能的影响,并从胞内聚合物的角度出发研究其机理。结果表明较低浓度的磺胺甲恶唑(0.05、0.1 mg/L)对生物除磷性能及典型周期内营养盐的利用、胞内聚合物含量无显著影响,当磺胺甲恶唑浓度提升至1 mg/L时,开始表现出抑制作用,且随着浓度的升高,抑制作用增强。在高浓度磺胺甲恶唑的存在下,活性污泥系统中COD去除率及除磷率最高降至79.64%及78.5%,且典型周期内有机物及正磷酸盐的消耗也受到明显的抑制,从而导致胞内poly-P、PHB、糖原降解及合成量受到显著影响。The effect of sulfamethoxazole on biological phosphorus removal was studied by establishing SBR reactor,and the mechanism was studied from the perspective of intracellular polymer.The results showed that the lower concentration of sulfamethoxazole(0.05,0.1 mg/L)had no significant effect on biological phosphorus removal performance,nutrient utilization and intracellular polymer content in typical cycles.When the concentration of sulfamethoxazole was increased to 1 mg/L,it began to show inhibitory effect,and the inhibitory effect increased with the increase of concentration.In the presence of high concentration of sulfamethoxazole,the COD removal rate and phosphorus removal rate in the activated sludge system are reduced to 79.64%and 78.5%respectively,and the consumption of organic matter and orthophosphate in the typical cycle is also significantly suppressed,resulting in a significant impact on the degradation and synthesis of intracellular poly-P,PHB,glycogen.
