求大神翻译一下!要专业一点排入高浓度耗氧有机物的河流、河涌会形成黑臭水质,河流存在厌氧河段,为了在这种情况下利用最常用的street-Phelps方程,进行规划、修复和治理河流水环境等工作,分析了一维稳态河流在点源高BOD初始浓度条件下出现厌氧河段的动力学机制,分几种类型推导出计算最大不厌氧初始BOD浓度的递归函数,以及计算厌氧河段开始处所对应的随流时间的递归函数.利用递归函数计算,可最大限度地减

水平有限,只能翻到这个程度了.
了作参考.Discharge of high-concentrated oxygen-consuming organic pounds into rivers or creeks can cause the formation of black & odorous water. In rivers there exist anaerobic stream segments, in order to utilize the mon-used Streeter-Phelps equation, and to implement the designing, repairing or bettering work for river's water circumstance, a couple of analysis work were done on the dynamic mechanism of how a anaerobic stream segment appears at one point-source under high BOD initial concentration in the one-dimension steady river. Based on this, recursive function of maximum non-anaerobic initial BOD concentration can be deduced in different modes, as well as the recursive function of follow-stream time at the beginning of anaerobic stream segment. With recursive function, the related calculation plexity can be reduced to the least, which can further provide a much more accurate & easier simulation of point-source high-concentrated BOD water quality via Streeter-Phelps Equation.
