Abstract

Abstract: In response to the difficulties in rural sewage treatment, high investment costs in infrastructure, and complex technology, the static test of wastewater from sewage treatment in the Cencun river, Guangzhou city, was carried out to simulate the discharge time of rural household sewage, and the treatment of sewage with the planting of Pennisetum sinese Roxb and Canna generalis L. was conducted. The results showed that compared with the control treatment, the removal rates of ammonia nitrogen, total nitrogen （TN） and total phosphorus （TP） of planting Pennisetum sinese Roxb and Canna generalis L. increased by 43.01,41.70 and 61.62, 60.44 percent, respectively, and the treatment of Pennisetum sinese Roxb was better than the treatment of planting Canna generalis L.. The removal rates of COD, TP, ammonia nitrogen, and TN in wastewater of Pennisetum sinese Roxb were 79.86%, 99.83%, 98.86% and 98.14%, respectively, while the Canna generalis L. was 57.51%, 98.65%, 98.18% and 96.83%, respectively.

Key words: rural domestic sewage, purification, Pennisetum sinese Roxb, Canna generalis L., static test
