海洋自絮凝菌在处理含盐污水中的应用研究
The application of Marine self-flocculating bacteria in the treatment of saline wastewater
摘要
Abstract
The microbial isolation and purification technique was used to successfully screen a strain Y25 with high flocculation activity from marine mud,which was identified as a Gram-positive bacterium be-longing to the genus Paenibacillus,with the highest degree of similarity to Paenibacillus chitinolyticus,by Gram staining and 16S rRNA sequence analysis.The effects of environmental parameters such as tem-perature,pH,dissolved oxygen and salinity on the growth characteristics of the strains were investigated by a one-factor experimental system,and their potential application value in the treatment of high-salt wastewater was evaluated.The experimental results showed that the flocculation activity of strain Y25 peaked at 26 h of incubation cycle,and its optimal culture conditions were 3％salinity(w/v),30℃,pH 7.0,and 200 r/min;in the simulated saline wastewater system,the removal of chemical oxygen demand(COD),total phosphorus(TP),and ammonia nitrogen(NH4+-N)by this strain could be up to 89.1％,76.7％,and 88.6％,respectively.The self-flocculating strains proved to be valuable for the application in the treatment of saline wastewater.关键词
