The Study on Waste Kitchen Water Treatment by Artificial Wetlands with Different Plant Configurations

The paper is aimed at studying the purification effects of COD, TN, TP and SS to waste kitchen water by using three different wetlands constituted by a single oenanthe javanica, single acorus calanmus, oenanthe javanica+acorus calanmus mixed configuration under the same load and the same hydraulic conditions. The results showed that oenanthe javanica is effectual for removing COD and TN, acorus calanmus is effectual for removing TP. As for the way of configuration, single configuration is preferred for removing COD, mixed configuration is preferred for removing TN and TP, the effect of the three configurations for removing SS is generally of the same level.
