微纳米气泡处理印染退浆废水

Treatment of desizing wastewater by micro-nano bubble

采用微纳米气泡法处理淀粉浆模拟废水,探究温度、pH、作用时间对淀粉浆分解率及COD去除率的影响。结果表明:在无任何助剂、温度80℃、pH 9左右、时间40 min的条件下,淀粉浆分解率为35.9%,COD去除率为28.9%。

The simulated wastewater of starch slurry was treated by micro nano bubble method.The effect of temperature,pH and reaction time on the decomposition rate of starch slurry and COD removal rate were investigated.The test showed that under the conditions of no additives,temperature 80℃,pH about 9 and time 40 min,the decomposition rate of starch slurry was 35.9%and the COD removal rate was 28.9%.
