摘要
剩余污泥的处理是生物法处理污水的一个重要内容。在多孔微生物载体固定床生物反应器中选用几种不同的好氧污泥,在厌氧条件下对其进行了降解研究,试验结果显示,总氮(T N)和氨氮(NH4+N)与总磷(T P)一样,可作为污泥降解性能的指标。好氧污泥的好氧降解、厌氧降解、好氧厌氧交替变化降解的试验结果显示,好氧厌氧条件下,污泥降解的最彻底。
Disposal of excess sludge is an important aspect in waste water treatment, Sludge degradation was done under anaerobic condition with different aerobic sludge which had been drawn from a fixed-bed bioreactor consisting of porous microbial carriers. The results show that T-N＆NH4^＋ -N as well as T-P could efficiently describe the extent of sludge degradation. Another experiment was done on sludge degradation under aerobic, anaerobic and aerobic-anaerobic conditions. Data show that aerobic-anaerobic condition can get the best results.
