摘要
以三峡库区江段主要有机污染水质指标BOD5为例 ,通过经验分析与计算 ,深入研究三峡水库建成前后水流条件巨大变化对BOD5生化降解系数K1 的影响 ,并建立了与水流条件相关的经验关系式。研究表明 ,三峡水库建成以后 ,随着水位抬高 ,流速减缓 ,单位时间内BOD5降解速率K1
With the main pollutant BOD 5 as an example and based on empirical analysis and calculation,the effect of great variation of water flow on the biodegradation rate of BOD\-5( K \-1)before and after the building of the Three\|Gorges Reservoir was studied.An empirical equation of K\-1 related with water velocity and depth was also developed.The results showed that after the building of the Three\|Gorges Reservoir,the biodegradation rate of BOD 5 would obviously decrease with the increase of water level and decrease of water velocity.
