摘要

Experimental vertical flow constructed wetlands were tested for their ability to remove two different azo dyes, Reactive Blue 171 and Acid Blue 113, from a simulated wastewater containing inorganic nutrients and glucose. The simulated wastewater was supplied continuously. The presence or absence of reeds or the aeration of the substratum had the greatest effect ont he rates of decolourisation of dye. Those planted with Phragmites australis removed the largest quantity (91percnet) of both types of dye. Most of the azo dye is removed int he first 12 hours by adsorption (57percent), largely to organic matter (31percent) and to roots and rhizomes (8percent) present in the substratum. After the first 3 days of exposure the efficiency of decolourisation increases by approximately 1 mg/dm~3/day.
