Abstract:
Be subjected to study the application in the hypersaline organic wastewater treatment,A moder-ately halophilic bacterium YS-1 was isolated from the salty water of a Ludaokou salina of Weihai in China.The polyphasic taxonomy study was processed through identifying its morphological features by AFM,researched the features of culture and measured physiologic-biochemical index,analyzed 16S rDNA se-quence homology Phylogenetic analysis based on 16S rDNA gene sequences showed that the closest relative of the strain was Halomonas sp.(AB167061).Experimented of intensifying hypersaline organic wastewater treatmented processing in the SBR demonstrate a significant result.The wastewater salt content of initial wastewater was 12% and initial CODcr was 1494 mg/L.After 72 h,the removal efficiency of CODcr achieved 90.0% and after 120 h,it achieved 98.1%.The experiments also showed the hypersaline organic wastewater treatment and presented the feasibility of acclimating of halophilic bacteria and running of proc-essing system.
