The result shows that the production of wastewater with high COD value was not favorable for plant growth. The plants were well grown to the wastewater after the biogas process and their tolerance was in descending order as follows: Umbrella sedge>

water spinach. The treatment efficiency of umbrella sedge was also superior to other species with the treatment efficiency from 82.3 - 98.4 %. Water spinach has the lowest treatment efficiency from 69.3 - 90.4 %. Taro is significantly treating better than water spinach, but lower than umbrella sedge. It can be seen that umbrella sedge is the most suitable plant species in the constructed wetland for wastewater treatment in Da Mai noodle handicraft village. However, the results have also shown that taro has great potential for application in treatment systems
