摘　　要：为提高有机污水处理效率,研究生化+MBR法处理效果,采取接触氧化生化法与分离式膜生物反应器处理人工模拟高浓度有机污水,通过有机污染物处理、氨氮处理、浊度处理、p H值变化分析降解特性。结果表明,以生化+MBR工艺处理高负荷、低负荷有机污水中,接触氧化池可去除污水有机物,加上MBR工艺降解污染物,可控制出水COD<50 mg/L,出水氨氮质量浓度均<2 mg/L,出水浊度在0.1~0.6 NTU以内,p H值稳定保持在6.5~7.3,均满足处理要求。可见,生化+MBR在膜法有机污水处理中具有良好效果,将其用于污水处理厂,能够提高有机污水处理效率。In order to improve the efficiency of organic wastewater treatment and study the treatment effect of biochemical+MBR method,contact oxidation biochemical method and separation membrane bioreactor were adopted to treat artificially simulated high concentration organic wastewater.The degradation characteristics were analyzed through organic pollutant treatment,ammonia nitrogen treatment,turbidity treatment,and pH value change.The results showed that using the biochemical+MBR process to treat high load and low load organic wastewater,the contact oxidation tank can remove organic matter from the wastewater.In addition,the MBR process can degrade pollutants and control the effluent COD<50 mg/L,the effluent ammonia nitrogen mass concentration<2 mg/L,the effluent turbidity within 0.1~0.6 NTU,and the pH value stable at 6.5~7.3,all of which meet the treatment requirements.It can be seen that the combination of biochemistry and MBR has a good effect in membrane organic wastewater treatment,and its use in wastewater treatment plants can improve the efficiency of organic wastewater treatment.
