Study on Wastewater Contaminant Removal Efficiency by Carbon Fiber Ecological Grass

摘要

The aim of this study is to investigate the contaminant removal efficiency in wastewater when disposed by carbon fiber ecological grass. The paper analyzed the TN, TP, COD_(Mn), (NH_4)~+-N and SS removal efficiency when used different dosage of carbon fiber ecological grass. The research results indicated that the contaminant removal efficiency at pH=8 is higher than pH=6, 7 and 9. When DO between 5.6 and 8, the TN, TP and (NH_4)~+-N removal efficiency has a highest level, the removal efficiency is 83.91%, 68.16% and 83.3% respectively. When DO between 8.1 and 10.7, the COD_(Mn) removal efficiency has a highest level, the removal efficiency is 57.93%. The stirring rate is important to the contaminant adsorption and removal. Consequently, selecting carbon fiber ecological grass in wastewater treatment is a good choice.
