This study investigated the microbial community of the sulfate-reducing up-flow sludge bed (SRUSB) of a novel sulfate reduction, autotrophic denitrification, and nitrification integrated (SANI®) process for saline sewage treatment. The investigation involved a lab-scale SANI® system treating synthetic saline sewage and a pilot-scale SANI® plant treating 10 m(3)/day of screened saline sewage. Sulfate-reducing bacteria (SRB) were the dominant population, responsible for more than 80% of the chemical oxygen demand removal, and no methane-producing archaea were detected in both SRUSBs. Thermotogales-like bacteria were the dominant SRB in the pilot-scale SRUSB while Desulforhopalus-like bacteria were the major species in the lab-scale SRUSB.
本研究调查了新型硫酸盐还原自养反硝化和硝化一体化（SANI®）工艺硫酸盐还原上向流污泥床（SRUSB）中的微生物群落，用于处理含盐污水。该研究涉及一个处理合成含盐污水的实验室规模 SANI®系统和一个处理 10 m³/天筛选含盐污水的中试规模 SANI®工厂。硫酸盐还原菌（SRB）是主要种群，负责去除超过 80%的化学需氧量，并且在两个 SRUSB 中均未检测到产甲烷古菌。在中试规模的 SRUSB 中，Thermotogales 样细菌是主要的硫酸盐还原菌，而在实验室规模的 SRUSB 中，Desulforhopalus 样细菌是主要的种。
