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,CODCr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.
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 CODcr, 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.
