摘 要: | Knowledge of phosphorus (P) variation regularity of sediment-water system has important influence on water pollution. Thus P variation regularity of top-sediment affected by some factors such as type of sediment (sandy and silty), background value of sediment, P concentration of overlaying water, inhibiter, disinfection, was investigated. The results stated that, (1) P in the sandy sediment occurred mainly in the form of insoluble P. Silty sediment with a low background level has higher dissoluble total phosphorus (DTP) content than silty sediment with a high background level. (2) Low-P primary liquid has low TP and DTP contents, TP in the overlying water was rich in DTP. While TP in overlying water of high P primary liquid was rich in insoluble total phosphorus (ITP). Overlying water of adding inhibitor set has high TP, dominated by ITP. TP in overlying water of no inhibitor set was dominated by DTP. Adding inhibitor set has obviously high pH value and tallish DO concentration in overlying water than in no inhibitor set. Disinfection set has high Pcontent in overlying water, DTP content is high. DO and ORP in overlying water of non-disinfection set were obviously higher than in that disinfection set.
