亚氧化钛修饰钛电极处理焦化废水的试验研究

Experimental study on coking wastewater treatment using Ti/TinO_(2n-1)electrode

采用自制亚氧化钛修饰钛电极装置处理焦化废水,考察了电流密度、p H值、处理时间对CODCr、氨氮、色度等处理效果的影响。研究结果表明,在电流密度为15 m A/cm2、p H值为3-5、处理时间为100 min的条件下,废水CODCr、氨氮、色度的去除率分别达到95.0%、99.5%、90.0%,该装置能有效地处理焦化废水。

Using the device assembled by self-prepared Ti/TinO2n-1 electrode to treat coking wastewater, me influences of current density, pH value and time on CODcr ammonia nitrogen and colority removal were investigated. The study results showed that, under the condition that current density was 15 mA/cm2, pH value was 3 - 5, treatment time was 100 min, the removal rates of CODcr, ammonia nitrogen and colority reached 95.0%, 99.5% and 90.0% respectively, which proved that the said device could treat coking wastewater effectively.
