【摘要】：为了提高SBR反应器的脱氮除磷性能,利用某校园厨余发酵液作为补充碳源进行生活污水处理试验研究。结果表明,发酵液中含有大量易降解有机物,能在厌氧条件下被微生物快速利用,实现较快的反硝化速率和释磷速率,投加厨余发酵液后,SBR反应器的脱氮除磷效果明显提高,对NH_4~+-N、TN、PO_4~(3-)-P的平均去除率分别达到了98%、78%、85%。试验过程中还发现,释磷和吸磷速率在第一阶段最大,硝化和反硝化速率在三个阶段均较高,但有所差异。进水中的PO_4~(3-)-P主要在第一阶段被去除,而TN主要在第二阶段被去除。
[Abstract]:In order to improve the performance of nitrogen and phosphorus removal in SBR reactor, the fermentation broth of kitchen waste from a campus was used as supplementary carbon source for domestic sewage treatment. The results showed that the fermentation broth contained a large number of easily degradable organic matter, which could be quickly utilized by microorganisms under anaerobic conditions to achieve faster denitrification rate and phosphorus release rate. after adding kitchen waste fermentation broth, the nitrogen and phosphorus removal effect of SBR reactor was obviously improved. For NH_4~-N, the average removal rates of PO 鈮，
