水环境中戊二醛消减速率影响因素的研究
Study of factors influencing the reduction rate of glutaraldehyde abatement in the aqueous environment
摘要
Abstract
In order to fully understand the retention time of glutaraldehyde in aqueous environments,experiments were conducted to preliminarily investigate the factors influencing the rate of glutaraldehyde abatement in water at three temperatures(20℃±1℃,25℃±1℃ and 30℃±1℃)and four salinities(0‰,10‰,20‰,and 32‰),respectively.The results were as follows:the temperature and salinity of the water environment had an effect on the rate of glutaraldehyde abatement,among which,the effect of temperature was more obvious.The rate of abatement of glutaraldehyde at a concentration of 500 mg/L in freshwater at three temperatures(20℃±1℃,25℃±1℃ and 30℃±1℃)was 2.51％,4.00％and 7.11％,respectively,in 24 hours.After 7 days,the rate of abatement was in the order of 15.39％,21.31％and 25.73％,respectively.The effect of salinity on the rate of glutaraldehyde abatement was small.At 2 days,the rate of glutaraldehyde abatement was 8.66％,9.00％,9.38％and 9.69％with the increase of salinity(0‰,10‰,20‰,32‰),and the difference was not obvious;at the time of 7 days,the rate of abatement of the various groups was 21.31％,24.60％,28.15％and 29.73％with the trend of increas-ing the differences.The results are helpful to understand the variation of glutaraldehyde concentration in water bodies with different temperature and salinity,and can provide reference for rational and effective use of glutaralde-hyde in aquaculture.关键词
