Three kinds of floating beds of aquatic plants floating bed with new types of fiber packing (A), aquatic plants floating bed with elastic packing (B), aquatic plants floating bed were established. The effect on the pollutant removal efficiency in wastewater from farmer household tourism at shiyanbaierhe was examined and the contaminant removal characteristic by different units was also analyzed. The results showed that floating bed system (A) showed very high removal efficiencies with respect to TN,NH4 + -N, CODcr and TP. Compared to floating bed (B) and (C), TN, NH4 + -N, CODcr and TP removal efficiencies of A rapidly increased at 15.3%、 33.2%; 18.8%、 34.7%; 16.4%、30.6%;18.3%、41.3% respectively while significantly higher than in black control with p<0.05. It showed the fiber packing was suitable for wastewater treatment which better than elastic space packing because of its excellent property.

Study on water quality improvement capacity by using floating bed made of fiber packing
