为提高赤霉素萃余液中 COD 降解率、减轻赤霉素萃余液对废水处理站运行负荷的压力,对土壤样品进行富集培养、分离筛选获得“三耐”高效微生物(菌或菌群),并以赤霉素萃余液为发酵基质,免蒸静止连续发酵获得高效降解赤霉素萃余液 COD 的微生物菌群。该混合菌群在赤霉素萃余液中能较好生长繁殖,培养7 d 后,赤霉素萃余液 COD 从约100000 mg·L-1下降到约40000 mg·L-1,COD 降解率达60%以上,为萃余液的处理开辟了新途径。
為提高赤黴素萃餘液中 COD 降解率、減輕赤黴素萃餘液對廢水處理站運行負荷的壓力,對土壤樣品進行富集培養、分離篩選穫得“三耐”高效微生物(菌或菌群),併以赤黴素萃餘液為髮酵基質,免蒸靜止連續髮酵穫得高效降解赤黴素萃餘液 COD 的微生物菌群。該混閤菌群在赤黴素萃餘液中能較好生長繁殖,培養7 d 後,赤黴素萃餘液 COD 從約100000 mg·L-1下降到約40000 mg·L-1,COD 降解率達60%以上,為萃餘液的處理開闢瞭新途徑。

To improve the degradation rate of COD in gibberellins raffinate,and relieve the pressure on the operating load of wastewater treatment,the high-efficient “three-resistant”microorganisms (single bacterium or mixed microbial consortium)were obtained by enrichment culture and isolation techniques,then the mixed mi-crobial consortium were inoculated in the gibberellins raffinate by free autoclaved static continuous fermentation to degrade the COD.The mixed microbial consortium propagated quickly in the gibberellins raffinate,the COD decreased from about 100 000 mg·L-1 to about 40 000 mg·L-1 after cultivation for 7 d,the degradation rate of COD was above 60%.
