Abstract: A coupled aerobic-anaerobic process was designed for treating organic wastewater from tomato paste processing.The process was based on a combined reactor of suspended bed and fixed bed to couple aerobic and anaerobic treatment.The removal rates of COD_Cr, BOD₅ and TP were 93.08%, 95.81% and 83.60% respectively.The pH reached 7.70.The effluent quality was not only up to the GB 18918—2002 Chinese National Second-Grade Effluent Standard, but also fit for recycling to tomato paste processing.After the coupled aerobic-anaerobic process was run for one year, the residual sludge was not discharged.

摘要： 开发了好氧-厌氧耦合法处理番茄酱加工有机废水工艺.该工艺集传统的悬浮式和固定式反应器于一体，将好氧和厌氧处理耦合在同一反应器中，工艺处理效果良好，COD_Cr去除率为93.08%，BOD₅去除率为95.81%，SS去除率为98%，TP的去除率为 83.60%，出水pH达到7.70.出水不但符合国家二级排放标准，而且能够回用于番茄酱加工.经1年的运行，未排放剩余污泥.
