Abstract
At present, the pollution by organics is a problem for a closed environmental water, in ponds and marshes. As such water as above, contains non- or less-biodegradable organics, represented by humics, in large amounts, their removal by biological treatments can be expected only a little, and many trials to decompose or reform the organics by an oxidation treatment such as ozonation, are being done.
In this study, an electrolytic oxidation treatment which had been conventional methods for organic syntheses and for other purposes was tried. The removal effect of humics was examined with an experimental apparatus of laboratory scale.
As for the electrolytic oxidation treatment, a certain effect for the removal of humics in term of TOC has been shown. And a decrease of a chromaticity has been shown, too. It was also found that there was a strong correlation between the removal ratio of TOC and the quantity of electricity.
