摘　　要：研究了二氧化氯(Cl O2)氧化/陶瓷超滤膜过滤工艺对屠宰废水的处理效果,对比不同Cl O2投加量、反冲条件(反冲周期、反冲时间等)对产水指标的影响,确定适宜参数。结果表明:其他条件相同,Cl O2投加量140 mg/L时,氧化单元COD去除率较高;反冲周期50 min、反冲时间50 s时渗透通量恢复较好,陶瓷膜装置运行效果最优,COD和浊度的总去除率分别达93.6%、95.8%,产水水质可达标排放,且运行总成本较低,有较好的工业推广前景。In order to determine the suitable operating parameters of oxide / ceramic-ultrafiltration-membrane filtration technology of the treatment progress on the slaughter wastewater,the paper was about the influence of Cl O2 dosage,backwash cycle and recoil time conditions on COD and turbidity. The experimental results showed that COD removal rate of oxidation unit was relatively high when Cl O2 dosage was 140 mg / L,the COD and turbidity removal rate was over 93. 6%,95. 8%respectively and the permeation flux recovered better on the conditions of backwash cycle time of 50 min,backwashing time of50 s. The quality of the produced water could meet the national discharge standard,and the total operation cost was low. This process had good prospects for industrial promotion.
