| 摘 要： | 由于高温好氧消化(TAD)后的污泥中常含有一定浓度的挥发性脂肪酸(VFA),为考察其对生物除磷系统的影响,通过将TAD污泥上清液与乙酸钠进行磷去除作用的对比试验。表明在厌氧条件下,加入TAD污泥的上清液,会使大量的P释放,磷释放规律及其释放速度均与乙酸钠造成的磷释放相当,因此,可以考虑将高温好氧消化污泥或上清液回流作为一种补充碳源,以强化生物除磷系统的除磷效果。但实际应用中,还要考虑到VFA降解以及回流污泥中的氮磷负荷,而且长期回流还需要进一步的试验验证。

| Abstract: | VFA was often accumulated in a thermophilic aerobic digestion(TAD)reactor during digestion.In order to test the effect of returned TAD sludge on biological phosporus removal system,contrasting test was carried out using supernatant of TAD and NaAc.Results showed that the rule and speed of phosphorus releasing in anaerobic phase were just the same no matter adding supernatant of TAD sludge or NaAc.So,it is considered that the returning TAD sludge or sludge supernatant can be used as a carbon source to streng... |
