  • 摘要: 在自制0.2 t/h气动超声吹脱实验装置中,通过自主研发的纳米复合脱氮剂(CT-601)与气动超声波的耦合作用,在不同氨氮初始浓度、吹脱时间、CT-601投加量、气液比等条件下对高浓度氨氮废水进行研究。结果发现,在常温下pH=11、气液比=900:1、脱氮剂投加量为0.0848 g/L时,超声吹脱60 min,处理2 000 mg/L的模拟废水时,去除率可达到93%以上,处理浓度为2 156 mg/L的实际废水时,去除率达到90%以上,较普通吹脱法和超声吹脱法分别提高40%和10%。同时还发现,该装置对COD去除率为29.72%,运行成本也只有7.24元/m3。
    Abstract: In the homemade pneumatic ultrasound stripping pilot plant of 0.2 t/h, pilot experimental study of high concentrations of ammonia nitrogen wastewater treatment was carried out through coupling effect of self researched and developed denitrification agent and pneumatic ultrasonic. The impacts of initial concentration, stripping time, CT-601 dosing quantity and gas liquid ratio on the removal of ammonia nitrogen were studied. The research results show that under the room temperature and pH was 11, gas-liquid ratio was 900:1, the denitrification agent dosing quantity was 0.0848 g/L, ultrasonic stripping was 60 min, when treating the concentration of 2 000 mg/L for simulated wastewater, the removal rate can reach above 93%, the concentration of 2 156 mg/L for the actual wastewater, removal rate reached more than 90%, compared with ordinary stripping and ultrasonic stripping, the ammonia nitrogen removal rate, increased by 40% and 10%, respectively.The removal rate of COD is 29.72%, the operating cost is only 7.24 yuan/m3.
