河流水环境中磷的迁移转化研究

hrough the experiment of concrete flume outside the house, to simulate the transformation of TP of river pollutants in different temperature, sediment and flow. The results of experiment show that in summer the removing effect of TP in gravel flume is better than that in soil flume, and the removing rate is more than 70%. In winter and low flow, the removing rate of TP in gravel flume is more than that in soil flume. Along with the increase of flow, the removing rates of TP in two flumes are close, exceeding 90%. The removing rate of TP in gravel flume has less affection by temperature, but the removing rate of TP in soil flume has more affection by temperature. The removing rate of TP in winter is higher than that in summer.
