The Variations of Organic Fluorescent Property in the Effluents from Biotreatment Unit Followed by Constructed Wetland Process

Abstract:

In this study, EEFM (Excitation emission fluorescent matrix) was used to evaluate the variation of organic characteristic of both source sewages into WuYiShan wastewater treatment. Similar organic property for both source sewages was identified, having four peaks, respectively belonging to fulvic acid, humic acid, aromatic protein and soluble microbial by-product. The fluorescent intensity (FI) of dominant humic acid fraction increased after biological treatment, and decreased in constructed wetland. UV process could result the increase of FI value of humic acid. However, the ratio of FI value of peak location in soluble microbial by-product to fulvic acid, called as Fs/Ff, continuously had an ascent after the biotreatment, constructed wetland and UV process. The organic property was apparently affected by the interior microorganism activity.
