摘　　要：为满足某豆制品产业园区发展需要,对其废水处理工程改扩建。在原有好氧处理工艺基础上,设计采用UASB-缺氧-好氧的组合工艺处理豆制品加工废水。工程运行结果表明,出水CODCr质量浓度为30~48 mg/L,BOD5质量浓度为6.7~12.5 mg/L,NH3-N质量浓度为3.4~7.3 mg/L,出水水质达到GB 18918—2002《城镇污水处理厂污染物排放标准》中一级B标准。In order to satisfy the demand for the development of a soya bean products industrial park, the wastewater treatment project of it was reconstructed and extended. On the basis of aerobic treatment, UASB-anoxia-aerobic combined process was adopted for the treatment of soya bean products processing wastewater. The operating results of the project showed that, when the mass concentrations of CODcr, BOD5 and NH3-N were 30 -48, 6.7 - 12.5 and 3.4 - 7.3 mg/L respectively, the effluent water quality met the specification for level B grade 1 in GB 18918--2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.
