Study on Wastewater Pollutant Removal Efficiencies of Artificial Aquatic Plants with Different Lengths

Abstract

Five different lengths artificial aquatic plants were used to purify wastewater. The artificial aquatic strings of 10cm diameter cylinder were divided into five groups, such as 0cm (A, CK), 50cm (B),100cm (C),150cm (D) and 200cm (E), respectively. The experimental results showed that the best removal efficiency was 78.3% and 73.5% for COD and ammonina nitrogen in the C group, and for the total phosphorus (TP), the best removal efficiency was 61.3% in the B group. Therefore, it is suggested that the best length is 100cm at 22°C to 26°C in the water according to the comprehensive removal efficiency.
