摘要：This work presents the use of marine halophilic bacteria on different cell carriers to treat saline wastewaters. A Gram-positive halophilic bacillus (HNPH) was isolated from sea mud sample obtained from Yellow Sea, China. The phylogenetic evolution tree built based on 16S rRNA gene sequence indicated the strain HNPH was in the same branch of A. halophilus (Alkalibacillus sp.YIM 012). The HNPH had high bioactivity in saline environments with salinity of 10%c~20%c (NaCl, w/v). Besides, the treatment of saline wastewater with salinity of 10% (NaCl, w/v) was studied using different cell carriers. Compare to the control group with COD degradation rate of 66%, the COD degradation rates using ceramsite, zeolite, tourmaline and activated carbon as cell carriers were 74%, 81%, 84% and 87%, respectively. The bacteria on tourmaline and activated carbon were showed with shorter lag period during the saline wastewater treatments.
