本研究利用铜绿微囊藻处理两种典型抗生素头孢拉定和阿莫西林.探究了铜绿微囊藻在光自养培养器中的受光特性,即光在培养器中的衰减效应以及藻细胞所接受到的光照强度;并在最佳的受光条件下研究了铜绿微囊藻的生长特性;最后选择最佳光照条件以及培养方式下的微藻对两种目标抗生素进行处理,并研究了光胁迫下铜绿微囊藻生长状况以及对抗生素的去除效果.结果表明在不同入射光强的照射下,铜绿微囊藻的生长性能有一定的差异.总体来说,当入射光为5500 lux时,微藻生长最佳;在一定范围内,光照强度越大抗生素去除效果越佳;此外铜绿微囊藻对头孢拉定和阿莫西林的去除率与黑暗处理时间有关,黑暗预处理3 d后的微藻对抗生素去除效果最佳,最高达到73.28 %.%Antibiotic wastewater issues affect the ecological environment and even the safe drinking water of residents, how to effectively deal with antibiotic wastewater is a topic of concern, antibiotics inhibit microorganisms in the conventional activated sludge, and thus this study attempts to utilize microalgae to treat target antibiotics.Microcystis aeruginosa was selected to treat two target antibiotics,cephradine and amoxicillin.The present study explored the feature of light that M. aeruginosa received in an autophototrophic incubator, namely light attenuation and light intensity in the incubator that the algal cells received; and the best lighting conditions was chosen to research the growth characteristics of M.aeruginosa.At last,the optimal light conditions and cultivation way,and the growth status and the antibiotic removal rate under the light condition was also explored. The results showed that there are certain differences in growth performance of M. aeruginosa under different incident light intensity.In general,5500 lux was the best light intensity for the algal growth.Within a certain range of light intensity,the stronger light intensity the greater removal rate of antibiotic; At the same time, the removal of cefradine and amoxicillin related to processing time in dark, M. aeruginosa that was pretreat in dark for 3 days show the best removal rate of antibiotic, which up to 73.28 %.
