In order to reduce the investment costs of the anaerobic side-stream reactor (ASSR) process coupled with an activated sludge system and promote the full scale application, the impact of 1 d anaerobic solid retention time (SRT_ASSR) and 100% interchange ratio (IR) has been investigated on sludge reduction, carbon and nutrient removal efficiency and microbial community, in a sequencing batch reactor (SBR)-ASSR system. The SBR-ASSR achieved good removal efficiencies in COD (91.5 ± 3.4%), ammonium nitrogen (98.8 ± 0.5%), total nitrogen (87.9 ± 4.9%) and phosphate (92.8 ± 6.7). The sludge yield of the system was 0.1648 g TSS g⁻¹COD; 54% lower compared to a conventional activated sludge (CAS) system. Real time quantitative polymerase chain reaction (q-PCR) showed an abundance of hydrolyzing and fermentative bacteria. Comparison at class and genus level confirmed an abundance of anaerobic hydrolyzing and fermentative bacteria, denitrifying bacteria able to simultaneous perform nitrogen and phosphate removal and phosphate accumulating organisms.

为了降低厌氧侧流反应器（ASSR）流程与活性污泥系统结合的投资成本并促进大规模应用，需考虑1 d厌氧固体保留时间（SRT _ASSR）和100％交换率（在定序分批反应器（SBR）-ASSR系统中，对IR（IR）进行了污泥减少，碳和养分去除效率以及微生物群落的研究。SBR-ASSR在COD（91.5±3.4％），铵态氮（98.8±0.5％），总氮（87.9±4.9％）和磷酸盐（92.8±6.7）方面实现了良好的去除效率。系统的污泥产量为0.1648 g TSS g ^-1化学需氧量 与传统的活性污泥（CAS）系统相比，降低了54％。实时定量聚合酶链反应（q-PCR）显示出大量的水解和发酵细菌。在类和属水平上的比较证实了厌氧水解和发酵细菌的丰富，反硝化细菌能够同时进行氮和磷酸盐的去除以及磷酸盐积累的生物。
