臭氧-活性炭法降低印染废水COD的研究

活性炭具有良好的催化性,臭氧具有良好的氧化作用。为了获得一种高效的去除废水COD方法,将臭氧通入添加活性炭的废水试样中。同时,依次通过改变废水样液的酸碱度、臭氧处理的时间和活性炭的含量这三个条件,进行了三组对比试验,得出最适宜、最高效的降低废水中COD的方法。此外还对处理废水进行总磷含量的测定。结果表明,活性炭对于臭氧的催化作用对于降低废水COD有重大影响,而且当反应环境处于碱性、30℃条件时可以在去除COD中发挥最大的效果,但对于去除总磷几乎无效。可以作为一种新型去除COD方法推广使用。

The Research of Using Activated Carbon and Ozone to Reduce COD in Waste Water

Activated carbon has a good catalyst and ozone has a good oxidation. In order to obtain an effective way to reduce COD in waste water, ozone was bubbled into the test solution added with activated carbon. In the meantime, three groups of check test with the change of pH, time of ozone supply and the temperature were done to find the most suitable and effective way to reduce COD in waste water. And the measurement of total phosphorus was done next. The result proves that activated carbon's catalyst has a big effect in reducing COD, and alkalinity and 30℃ are the suitable environment for its operating. Though this way is useless for total phosphorus, it can be used as a new way dealing with COD in waste water.
