Abstract

Taking the water, sediment, and Potamogeton crispus collected from Shihoudian, Wangjiazhai, and Xiaodian in Baiyangdian Lake area into laboratory, three simulated static systems were built to study the growth of P. crispus and its effect on the removal of total phosphorus from eutrophic water and sediment. Among the three systems, Shihoudian system had the best purification effect, with the removal efficiency of total phosphorus from water body being 87.9%, followed by Wangjiazhai system 47.4%, and Xiaodian system 76.9%. The largest total phosphorus removal efficiency per gram biomass in Shihoudian, Wangjiazhai, and Xiaodian systems was 2.2%, 0.9%, and 1.4%, and the largest total phosphorus adsorption rate of sediments was 9.1%, 7.4%, and 7.7%, respectively. The TP-t and v-t fitted equations of the three systems indicated that the total phosphorus concentration in water and the removal rate of the total phosphorus were negatively exponentially decreased with time.
