摘　　要：本试验采用混凝沉淀和气浮工艺处理高浓度土霉素废水,结果表明,作为预处理工艺,这套工艺在技术上是可行的;在石灰投加量为1500mg/L、PAC投加量为2250 mg/L、PAM投加量为4 mg/L的条件下,混凝沉淀的CODCr去除率达到75.8%,BOD5/CODCr的值由原来的0.15提高到0.32。Coagulation, sedimentation and air floatation are used to treat high concentration wastewater of terramycin in the experiments. In terms of technology, the process is feasible as a pretreating way. The CODcr removal rate of coagulation/sedimentation is 75.8% at lime dosage of 1500mg/L, PAC of 2250 mg/L, and PAM of 4 mg/L. The ratio of BOD5/CODcr increases from 0.15 to 0.32 after treatment.
