摘　　要： 将生物滤池与活性污泥池串联形成一个生化处理系统,生物质煤气洗涤废水经过预处理后,采用ASBRO和AO1O2两种联合工艺进行处理,着重考察了系统对生物质煤气洗涤废水CODCr、NH+4N的降低效果。采用ASBRO工艺,CODCr的去除率平均达到85.4%,NH+4N平均去除率为33.5%;采用AO1O2工艺,CODCr的去除率平均达到78.2%。NH+4N平均去除率为22.7%。 The application of treating gas-washed wastewater from biomass gasifier by a combined system is presented.This system is combined biofilter with activated sludge pool,and treatment of this wastewater by A-SBR-O and A-O_1-O_2 methods is investigated.COD_ Cr removal rate of 85.4% and average NH^+_4-N removal rate of 33.5% are obtained. This system can remove the COD_ Cr efficiently by A-O_1-O_2 method, with average COD_ Cr removal rate of 78.2% and average NH^+_4-N removal rate of 22.7%.
