摘要
成都绿水科技有限公司开发了一种新型射流曝气器,该射流曝气器与传统射流曝气器相比,在喷嘴形状、吸气室、喉管段、扩散管、导流片均有所创新。结合纯氧曝气,其已成功应用于重钢焦化厂焦化废水处理。结果表明:该设备充氧动力效率高,可达5.31 kg/(kW.h),仅用较少供氧量便可保证溶解氧浓度在2 mg/L以上,纯氧利用效率可达91%以上,且抗冲击负荷能力强,泡沫少,电耗、运行成本低。
A novel jet aerator was developed by Chengdu Greenwater Technology Co.,Ltd.Compared with traditional jet aerators,innovations exhibited in terms of nozzle＇s shape,induction chamber,larynx tube segment,diffusion tube and flow deflector.With pure oxygen aeration,this new jet aerator has been successfully used in the disposal of coking wastewater from Chongqing Steel Group.The results showed that an oxygenation efficiency as high as 5.31 kg/（kW·h） could be achieved and the concentration of dissolved oxygen could be maintained over 2 mg/L at a relatively low level of oxygen supply.What＇s more,the oxygen utilization efficiency could exceed 91%.Meanwhile,it showed strong resistance to shock load and produced less bubbles.The operational cost was also lowered due to less power consumption.
