| 摘 要： | 采用强电场电离放电制取高浓度的活性氧分子O2+和O3,这些活性氧分子与污水中水反应生成羟基自由基OH,可快速把污水中COD降解成无害的CO2、H2O,污水中COD浓度从132 mg/L降至22.6mg/L,COD的去除率达到82.9%,达到回用水质量标准(≤ 50 mg/L),该方法有助于解决目前污水回用存在的问题。

| Abstract: | In this study,a large number of reactive oxygen molecule(O2+,O3) produced by strong ionization discharges reacted with H2O in the sewage to form OH free radicals.OH could high-effectively and quickly degrade the COD of sewage to CO2 and H2O.The COD concentration in sewage was decreased from 132 mg/L to 22.6 mg/L,and the removal rate reached 82.9%.The COD concentration in sewage after reactive oxygen molecule treatment could meet the water quality standard(≤ 50 mg/L),which is helpful to solving the existing technical problems in sewage reuse. |

| Keywords: | COD removal rate advanced treatment of wastewater strong ionization discharge reactive oxygen molecule |
