在室温下,研究了不同有效氯浓度对新月菱形藻、扁藻、球等鞭金藻和湛江等鞭金藻种群增长的影响,以及在 10 mg/L的有效氯浓度下,不同接种时间对扁藻种群增长的影响。结果表明:1mg/L以上的有效氯对单胞藻的种群增长已产生了抑制作用,随着有效氯浓度的增加,其抑制作用增强。几种饵料藻类对有效氯的耐受顺序为:等鞭金藻＞扁藻＞新月菱形藻。有效氯对单胞藻的毒性作用不但与有效氯的初始浓度有关,而且与有效氯的衰减密切相关。有效氯浓度相同时,对单胞藻生长的抑制作用随接种时间的延后而减小。
At room temperature, the effects of different available chlorine concentrations on the population growth of C. marinatus, P. alga, Isochrysis galbana, and Isochrysis galbana were studied, and the effects of different inoculation time Effect on the growth of Platymonas sp. The results showed that 1 mg / L of available chlorine had an inhibitory effect on the population growth of Monocytogenes, and its inhibitory effect was enhanced with the increase of effective chlorine concentration. Several bait algae to chlorine tolerance sequence: Isochrysis> Platymonas sp The toxic effects of available chlorine on monocytogenes are not only related to the initial concentration of available chlorine, but also to the decay of available chlorine. When the effective chlorine concentration is the same, the inhibitory effect on the growth of monocytogenes decreases with the delay of inoculation time.
