| 中文摘要 |
| 对聚β-羟基丁酸(PHB)及β-羟基丁酸与β-羟基戊酸的共聚物(PHBV)薄膜和粉膜在好氧污泥和厌氧污泥中的生物降解性进行了研究,并对其降解机制作了初步探讨。结果表明:污泥中的微生物可以利用PHB(V)作为唯一碳源生长繁殖;PHB的降解能力比PHBV的高;不同pH、温度对污泥中微生物降解PHB(V)的能力有着不同的影响;制品形态,特别是添加量,与降解率有很大关系,添加量越大降解率越高。 |
| 英文摘要 |
| Biodegradation process and mechnism of poly-β-hydrox ybuty rate(PHB)and poly(β-hydrox -ybutyr ate-co-β-hydr oxy valerate)(PHBV)were studied in aerobic and anaerobic sludge. Micro organisms in sludge can grow using PHB(V)as sole carbon source. Bio degradation rate of PHB is faster than that of PHBV. Different conditions, such as pH and temperatures, have different influence on microbial degradation abilities of PHB(V)in sludge. Product configuration, especially specific surface area, has close correlation with the rate, and the larger specific surface area is, the faster biodegradation rate is. |
