摘  要:在严格控制试验条件的基础上,首次采用IOC-SBBR联合工艺处理高氨氮猪场废水。结果表明:经过62d逐步提高IOC进水COD,提升反应器容积负荷至6kg/(m3·d),COD去除率达到81.5%;SBBR经过24d的生物膜驯化,COD、NH4+-N的去除率可以达到85%和90%以上,联合工艺启动成功并可稳定运行;再经过2个阶段(56d)的对比研究,优化SBBR运行方式,增加缺氧-好氧交替频次,联合工艺的COD、NH4+-N和TN去除率达到95.6%、95.4%和78.6%。Under the well-controlled experimental conditions,the combined internal and outer circulation reactor(IOC) and sequencing batch biofilm reactor(SBBR) process has been used the first time for treating piggery wastewater that bears high ammonia-nitrogen.The results show that the COD removal rate reaches 81.5%,after 62 d has gradually increased the concentration of IOC influent COD and the reactor volumetric loading of IOC to 6 kg/(m^3·d).COD and NH4^+-N of SBBR removal rates could be higher than 85% and 90%,respectively,after SBBR was biologically cultivated for 24 d.The combined process starts up successfully and runs stably.In the two stages(56 d) comparative studies,optimizing SBBR operation mode and increasing the anoxic-aerobic alternative frequency,the removal rates of COD,NH4+-N and the TN of the combined process reach 95.6%,95.4% and 78.6%,respectively.
