摘　　要：好氧缺氧一体化的高效分离生物流化复合反应器(HSBCR)是在内循环三相生物流化床的基础上发展起来的一种新型反应器。考察HSBCR在较短停留时间内处理生活污水时的脱碳、脱氮和除磷效果,结果表明:好氧区HRT为1.5 h时,CODCr、氨氮、总氮、总磷去除率分别为81%、51%、47%和50%;HRT为2.0 h时分别为84%、64%、54%和57%。HSBCR不仅能在短时间内使CODCr快速高效地去除,而且可以实现硝化与反硝化的一体化,满足脱氮除磷的要求,有望成为小城镇污水处理的适用技术。An integrated reactor, which had an aerobic zone combined with an anoxic zone in an improved internal-loop bio-fluidized bed, was developed and studied the pollutant removal performance when to treat domestic sewage. About 81% of COD_(Cr), 51% of ammonia, 47% of total nitrogen and 50% of total phosphorus were removed at hydraulic retention time (HRT) of 1.5 h, while the removal rates increased to 84%、64%、54% and 57% at HRT of 2.0 h, respectively. The above results suggest the application potential of the reactor to town and country for wastewater treatment, where requires to simultaneously remove organic carbon, nitrogen and phosphorus in some simple and cheap process.
