| 摘 要： | 采用微纳米气泡曝气的方式处理染料蓝1为原料配制的模拟水性油墨废水，以废水中的染料浓度、COD及氨氮去除效果作为考察指标，探讨废水中不同初始pH值、NaCl投加量、H2O2添加量对微纳米气浮法处理油墨废水的影响效果。实验结果表明:采用微纳米气浮去除油墨废水污染物能达到较好的效果，不同的反应条件有效促进了微纳气泡的曝气吸附作用，其中在pH为5的条件下处理效果最佳，染料浓度和COD去除率分别达到90.0%以上，氨氮去除率也达到75.4%。

| Abstract: | The simulated water-based ink wastewater was treated by micro nano bubble aeration. The effects of different initial pH value, NaCl dosage and H2O2 dosage on the treatment of ink wastewater by micro nano air floatation were discussed by taking the dye concentration, COD and ammonia nitrogen removal efficiency as the inspection indexes. The experimental results showed that the micro nano air flotation could achieve better results in the removal of ink wastewater pollutants, and different reaction conditions could effectively promote the aeration adsorption of micro nano bubbles, among which the treatment effect was the best under the condition of pH 5, the removal rate of dye concentration and COD were over 90.0%, and the removal rate of ammonia nitrogen was 75.4%. |
