摘　　要：洛阳技术研发中心开发的生物流化床反应器,考察其对不同水质污水的处理效果,分别对炼油污水、乙二醇污水、PTA污水和煤制乙二醇污水等四种污水进行了1~3个月的连续试验。试验表明,在炼油污水进水COD为300~800mg/L、NH3-N为30~60mg/L的条件下,经处理后,出水COD<80mg/L、NH3-N<15mg/L,污水的COD去除率>85%,NH3-N去除率>90%;在乙二醇污水进水COD为1500~2500mg/L的条件下,经处理后,出水COD<500mg/L;在PTA污水进水COD为1000~4700mg/L的条件下,出水COD<300mg/L,去除率>90%;在煤制乙二醇污水进水COD为200~2000mg/L、NH3-N为18~130mg/L的条件下,处理后的出水平均COD<60mg/L、去除率超过90%,平均NH3-N <8mg/L、去除率大于85%。试验结果表明,生物流化床反应器具有比表面积大、微生物浓度高、容积负荷率和污泥负荷率高、传质快、耐冲击负荷能力强、处理效果好等特点,对不同水质的污水均能达到良好的处理效果。To investigate the effect of biological fluidized bed reactor developed by Luoyang R&D Center of Technology in treating wastewater with different water quality,1 ~3 month continuous operation test was performed to treat refinery wastewater,ethylene glycol wastewater,PTA wastewater and coal-based EG wastewater respectively.The results showed that when the COD and NH3-N of inlet refinery wastewater were 300 ~800 mg/L and 30 ~60 mg/L respectively,the COD and NH3-N of outlet water were lower than 80 mg/L and 15 mg/L respectively,with a COD and NH3-N removal rate of higher than 85% and 90% respectively.When the COD of inlet ethylene glycol wastewater was 1500 ~2500 mg/L,the COD of outlet water was lower than 500 mg/L.When the COD of inlet PTA wastewater was 1000 ~4700 mg/L,the COD of outlet water was lower than 300 mg/L,with a COD removal rate of higher than 90%.When the COD and NH3-N of inlet coal-based EG wastewater was 200 ~2000 mg/L and 18 ~130 mg/L respectively,the average COD and NH3-N of outlet water was lower than 60 mg/L and 8 mg/L respectively,with a COD and NH3-N removal rate of higher than 90%and 85% respectively.The test results showed that the biological fluidized bed reactor has the characteristics of large specific surface area,high microbial concentration,high volume loading rate and sludge loading rate,fast mass transfer,strong impact load resistance and good treatment effect,and good treatment effect can be achieved for wastewater with different water quality.
