摘要
本论文从河流的BOD速率常数 K,生态环境,各个排污口的位置三方面考虑,对“用电脑程序测定河流环境容量”的方法作了一定的研究。这种方法比我国目前在水质管理方面采用的“浓度控制”方法更为合理科学,在未来具有很大的前景。论文中程序部分是对这种方法具体研究的详细过程。实验部分提供了程序部分需要的原始数据,将原始数据输入程序在电脑中运行,可得到河流的环境容量与各个排污口允许排放的最大BOD浓度。从程序部分可以得:出河流各段排污口允许排放的最大BOD浓度各不相同;从实验部分得出河流的BOD速率常数 K越大,河流的自净效率越高,容纳污染物的能力越强,环境容量越大。

This paper is from BOD speed constant K of river , ecological environment, the location 3 of every sewage draining exit aspect consideration, for the method of " use computer program mensuration river environmental capacity ", have made certain research. This kind of method is more reasonable and more scientific than the method of " concentration control " that our country now adopts in the aspect of the management of water quality, in do not come to have great prospect. The paper order part of intermediate range is the detailed course for this kind of method specific research. The experiment original data that has offered program partial needs partially runs original data input program in computer, can get every sewage draining exit and the environmental capacity of river to allow the biggest BOD density of emission. From program part, it is each not identical to be able to reach each section sewage draining exit of river to allow the biggest BOD density of emission; The more from experiment BOD speed constant K that reaches river partially big, the more river from net efficiency is high , the ability that holds contaminant is the more strong, environmental capacity is the more big.
