Abstract

Abstract

The water-sediment-Hydrilla verticillata system was simulated with several measures such as controlling temperature and light in the walk-in simulation laboratory. The control group and the 30g, 60g Hydrilla verticillata group were naturally decomposed, the variation of Hydrilla biomass and total phosphorus and various forms of phosphorus in the water were detected during the decay of Hydrilla verticillata, to discusss the transportation and transformation of phosphorus within the system. The results showed that the decomposition of Hydrilla verticillata had obvious stages, and the decomposition rate in the early stage of the experiment was significantly higher than that in the middle and late stage. During the experiment, the trend of DO change in the Hydrilla verticillata groups was first decreased and then increased with consistency, and the change interval of pH value was between 7.4 and 8.4, with little surges. In the control group and the 30 g Hydrilla verticillata group, the ORP showed a trend of increasing first and then decreasing. The ORP of the 60g kelp group decreased first and then increased. During the whole research period, the phosphorus contents of the groups were in the order of 60 g Hydrilla verticillata > 30 g > the control group. The decomposing of Hydrilla verticilla changed the circulation of phosphorus in the system, inhibited the release of phosphorus in the sediment in the early stage of decomposing, promoted the release of phosphorus in the late stage of decomposing, and had a significant effect on the migration and transformation of various forms of phosphorus.
