| 摘 要： | 采用序批式反应器(SBR),对比厌氧/好氧(A/O)和厌氧/缺氧(A/A)2种运行模式对模拟生活和工业混合污水同时脱氮除磷的效能。结果表明:反硝化聚磷菌完全可以在厌氧/缺氧交替运行条件下得到富集,稳定运行的2种模式对有机物和P的去除率分别保持在90%和85%以上,且A/A SBR具有更强的释磷能力,其释磷量比A/O SBR高出1.2倍。进一步试验表明:磷的释放在有无硝酸盐的情况下效果是不同的。2个系统内污泥均有反硝化除磷能力,A/A SBR中所含反硝化聚磷菌(DPAO)的比例是A/O SBR的4.56倍。2种模式出水水质都能取得较好的效果,且能实现同步除磷脱氮,而反硝化除磷在生物除磷方面更具优势。

| Abstract: | Two sequence batch reactors(SBRs) in A/O and A/A run modes were operated in parallel to compare their ability of simultaneous phosphorus and nitrogen removal.The results showed that the ability of the anaerobic/anoxic strategy enriched the growth of denitrifying phosphorus bacteria capable of taking up phosphate under anoxic condition,and the removal of COD and phosphorus were averaged over 90% and 85% in the steady-state,respectively.A/A SBR had the stronger anaerobic phosphorus release ability;its amount ... |
