带辐照改性聚丙烯填料的气升式内环流反应器处理废水的研究

Study on wastewater treatment in an airlift internal loop Reactor with radiated grafting filler

应用高能射线辐照技术,在聚丙烯填料表面接枝丙烯酸单体进行改性。将此改性填料应用于气升式内环流反应器中,并对模拟生活废水进行间歇法和连续法处理。实验结果表明,该反应器运行稳定,适应浓度范围广,COD去除率较高,出水COD浓度波动小。

By the high-energy radial, acrylic monomer is grafted on the surface of polypropylene filler. The radiated grafting filler is used in an airlift internal loop reactor to treat the simulated wastewater. The experiments are done in the batch way and the continuous way. The results show that it has a preferable effect in different COD concentration, high COD removal rate and little COD change in effluent.
