浅议UASB+SBR工艺在酒精工业废水处理中的应用

采用上流式厌氧污泥床(UASB)加间歇式活性污泥法(SBR)综合工艺处理玉米酒精工业废水，经2年多运行表明，运行费用低、效果好，处理后的污水达标排放，还可作为中水回用。污水先经预处理系统(包括事故调节池、集水池、pH调节、冷却塔)处理后进入UASB反应器处理，经处理后出水CODcr去除率达76％，BOD去除率达83％。然后进入SBR池处理。CODcr去除率达91％，BOD5去除率达95％。处理后的水经活性炭吸咐处理后可作中水使用。

Application of UASB+SBR Technology in the Treatment of Alcohol Industrial Sewage

UASB+SBR technology had been applied to treat corn alcohol industrial sewage for more than two years and the application results indicated that the operation cost was low, good effects achieved, and water managed was in accord with sewage discharge standard and could be reused as medium water. The sewage first treated by pretreatment system (including accidents regulation pits, collecting tank, pH adjustment, and cooling tower), then treated by UASB reactor, the removal rate of CODcr of water after treatment was 76 % and removal rate of BOD reached 83 %, finally the water flew into SBR pits for further treatment, the removal rate of CODcr and BOD5 reached 91 % and 95 % respectively. The managed water then treated by active carbon absorption could be used as medium water. (Tran. by YUE Yang)
