| 摘 要： | 投加絮凝剂是促使微生物快速形成污泥颗粒的一种有效手段,通过研究在不同絮凝剂下生成的生物絮体的形态和沉降性能,推荐选用聚合氯化铝(PAC)作为促进光合细菌球形红细菌形成污泥颗粒的絮凝剂。PAC的最佳投加量范围为140-160mg/L,其中,PAC投加量150mg/L时,促进污泥颗粒化的效果最好。考察球形红细菌污泥颗粒降解氯苯的环境条件,结果表明球形红细菌污泥颗粒降解氯苯的最佳条件为好氧、pH7.0、30°C。 |

| Abstract: | Influences of several different kinds of flocculating agent on photosynthetic bacteria Rhodobacter sphaeroides were assessed by analyzing settling performances and strength of bioflocculates. From the results, polychlorinated alumina (PAC) was finally selected as a flocculating agent to accelerate formation of granular sludge of Rhodobacter sphaeroides. Tests gave the dose of PAC in the range of 140-160 mg/L. When the dose of PAC was 150 mg/L, granulation was the most effective. The degradation efficiency and reaction parameters were investigated on treating chlorobenzene in water by granular sludge of Rhodobacter sphaeroides. The results showed that the optimal conditions of treatment for chlorobenzene in water by granular sludge of Rhodobacter sphaeroides were aerobic condition, temperature 30oC and pH 7.0. |
