【摘要】 自制电压为10kV 的高压脉冲放电反应器,对质量浓度为200mg/L 的模拟活性艳红 K-2BP 废水进行脱色和去除 COD 实验。实验结果表明:通氧气高压脉冲放电与高压脉冲放电相比,废水脱色率提高了1.3%,约为6%,COD 去除率提高了3%,达14%;高压脉冲放电协同臭氧氧化与臭氧氧化相比,反应初期废水脱色率提高了约10%,反应30 min 后废水脱色率均达99%以上,COD 去除率提高了15.2%,达80%。向废水中加入 Na2CO3可使 COD 去除率明显下降;加入NaCl,在臭氧氧化条件下,COD 去除率由66.86%降至58.86%;而加入 Na2SO4后 COD 去除率升至81.70%。

【Abstract】 The experiments on the removal of color and COD from simulated wastewater containing 200 mg/L reactive brilliant red K-2BP were carried out in the self-made high voltage pulse discharge reactor with 10 kV of voltage.The experimental results show that:Compared with high-voltage pulse discharge process,the wastewater treated by high-voltage pulse discharge-O2 process has a color removal rate of 6%,increased by 1.3%,and a COD removal rate of 14%,increased by 3%;Compared with ozonation process ,the wastewater treated by high-voltage pulse discharge-ozonation process has a color removal rate increased by about 10% in the initial reaction stage,and after treated for 30 min,the removal rate of color is above 99% and that of COD is 80%,increased by 15.2%;Adding Na2 CO3 can result in a visible decrease of COD removal rate;Adding NaCl can result in the decrease of COD removal rate from 66.86% to 58.86% under the condition of ozonation;Adding Na2SO4 can result in the increase of COD removal rate to 81.70%.
