| 摘 要： | H2O2协同臭氧氧化实验中,对于初始pH值为6.8的500 mL废水,在臭氧投加量为48 mg,0.1 mL H2O2在反应前加注到反应器的条件下,O3/H2O2工艺的COD cr去除率比臭氧单独氧化提高了7.9%。对于O3/H2O2工艺,其最佳H2O2投加量随废水pH值的增加而减少;一次投加H2O2方式的COD cr去除率在大部分时间内都好于间歇投加H2O2方式。

| Abstract: | In the ozonation cooperated with H2O2,for the 500 mL wastewater with initial pH value of 6.8,when ozone dosage was 48 mg and 0.1 mL H2O2 was added in reactor before reaction,the removal rate of CODcr in O3/H2O2 is higher than the removal rate of CODcr in ozonation alone 7.9%.For O3/H2O2 process,with increasing the initial pH value of wastewater,the optimum dosage of H2O2 decreased.The removal rate of CODcr in most time by pre-adding is better than that by intermittent adding. |
