【摘要】:為了提高SBR反應(yīng)器的脫氮除磷性能,利用某校園廚余發(fā)酵液作為補(bǔ)充碳源進(jìn)行生活污水處理試驗(yàn)研究。結(jié)果表明,發(fā)酵液中含有大量易降解有機(jī)物,能在厭氧條件下被微生物快速利用,實(shí)現(xiàn)較快的反硝化速率和釋磷速率,投加廚余發(fā)酵液后,SBR反應(yīng)器的脫氮除磷效果明顯提高,對(duì)NH_4~+-N、TN、PO_4~(3-)-P的平均去除率分別達(dá)到了98%、78%、85%。試驗(yàn)過程中還發(fā)現(xiàn),釋磷和吸磷速率在第一階段最大,硝化和反硝化速率在三個(gè)階段均較高,但有所差異。進(jìn)水中的PO_4~(3-)-P主要在第一階段被去除,而TN主要在第二階段被去除。
[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,
