Abstract

Pilot-scale constructed wetlands planted the reed was constructed to treat papermaking water. The treatment performances of the three wetlands with different operation model for COD, ammonia nitrogen, total phosphorous, BOD5 were investigated. The results show that the removal efficiency of all kinds of pollution indicators for the sequencing batch wetland of alternating dry and wet is better than that of the continuous wetland, and the performance of systems achieved the best in September and October and declined from November. When effective area of wetlands was 30hm3, irrigation water depth 8cm, pollutants surface loading 2cm/d,and continuous 8d and intermittent 2d at every year in September, the removal efficiency of COD, ammonia nitrogen, total phosphorous and BOD5 was reached to 34%, 28%, 25%and 46%, respectively. The quality of the outlet water met the requirement of recycle water and discharge standard.
