摘　　要：采用物化手段和生化手段相结合的方法处理豆制品废水,在生化反应前增加混凝、气浮物化处理手段,大大降低了COD的有机负荷,提高了废水的可生化性.在生化处理阶段进水COD为500mg/L～2000mg/L的情况下,出水COD可降到150mg/L以下,达到国家二级排放标准.该组合工艺处理豆制品废水具有COD去除率高、出水水质稳定、运行管理方便等特点.The treatment of soya bean wastewater is studied with coagulation air-flotation and biocontact oxidation. The influent COD is distributed from 500 mg/L to 2000 mg/L, and the effluent COD is less than 150 mg/L. Which meets the requirement of the Second National Discharge Standard for wastewater in China. This method has the advantages such as high COD removal efficiency and easy management.
