N2 - Wastewater recycling is one of key technologies for the environmental control and life support system (ECLSS). In this paper, a biological treatment system (BTS) was designed, consisting of two sequencing batch reactor (SBR), an oxygen supplier, a detecting module, and a controlling module. The hygiene wastewater and urine could be treated simultaneously by the system designed, and the effluent water could be used as nutrition solution. When treatment system was under stable operation, the removal rate of chemical oxygen demand (COD) and urea nitrogen reached 99.34%, 87.2%, respectively, and the nitrate concentration in effluent water was 1 626.7 mg/L. The composition of microbial community in SBR was analyzed, finding that more than 73.3% of the microorganisms belong to Pseudomonas spp. and Arenimonas spp. in the hygiene wastewater bioreactor, and more than 48.8% of the microorganisms belong to Thauera spp., Nitrosomonas spp., and Comamonas spp. in the urine wastewater bioreactor. These microorganisms can play an important role in stabilizing of the BTS. This study provides a theoretical basis for application of BTS for treatment of space wastewater.
