用電腦程序測定渭河環(huán)境容量的研究

全文72頁 約20000字 論述翔實

摘要
本論文從河流的BOD速率常數(shù) K，生態(tài)環(huán)境，各個排污口的位置三方面考慮，對“用電腦程序測定河流環(huán)境容量”的方法作了一定的研究。這種方法比我國目前在水質(zhì)管理方面采用的“濃度控制”方法更為合理科學，在未來具有很大的前景。論文中程序部分是對這種方法具體研究的詳細過程。實驗部分提供了程序部分需要的原始數(shù)據(jù)，將原始數(shù)據(jù)輸入程序在電腦中運行，可得到河流的環(huán)境容量與各個排污口允許排放的最大BOD濃度。從程序部分可以得：出河流各段排污口允許排放的最大BOD濃度各不相同；從實驗部分得出河流的BOD速率常數(shù) K越大，河流的自凈效率越高，容納污染物的能力越強，環(huán)境容量越大。

關(guān)鍵詞：環(huán)境容量,BOD速率常數(shù),溶解氧,虧氧量,氧垂曲線

Survey with computer program Wei river( the section of Xi'an) environment the research of capacity
Make a summary
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.
Keyword: Environmental capacity、 BOD speed constant、 dissolved oxygen 、 loss oxygen 、oxygen Chui curve
