摘要
采用闭合循环实验方法,观测了厦门西港底质耗氧过程。结果显示底质耗氧随时间变化呈非线性,可用指数方程SOD=ρ·exp(—k/t)表示.计算得厦门西港底质耗氧速率均值为405.8mg/(m^2·d)。在底质耗氧过程中,底质释放出有机物质,底质释放COD 速率为93.6mg/(m^2·d),底质耗氧作用与底质有机物质的释放有关.
The experiment method of closed cycle is use to examine the oxygen demand process of sedimentin the Xiamen West Harbour.The results show that SOD may be expressed by the following exponen-tial:SOD=ρ.exp(-k/t).The rate of SOD was calculated as 405.8mg/(m^2·d)in average.The or-ganic matters released from sediment in the oxygen demand process with a rate of 93.6mg/(m^2·d).There is a significant relationship between SOD and organic matters.
