  • 摘要: 研究以SBBR为对象,考察碳源种类对原位生物解偶联污泥减量系统污泥产率和污水处理效能的影响。研究结果表明,在水温为25℃,挂膜密度为45%,负荷为4.0 kg COD/(m3填料·d),供气量为150 L/h,采用间歇曝气30 min/停曝30 min的方波供氧条件下,碳源种类对原位生物解偶联污泥减量系统效能影响显著。当进水有机质为葡萄糖时,系统污泥产率最小,为0.0292 kg MLSS/kg COD,分别比进水碳源为粪水、乙酸钠、淀粉时减少19.4%、64.8%和99.9%。碳源为葡萄糖时,系统出水COD、NH4+-N、TN分别为41、6.4和17.3 mg/L,可达标排放。
    Abstract: The influences of carbon sources on sludge reduction efficiency were studied in SBBR in-situ sludge reduction system. The results showed that the carbon sources had obvious effect on the sludge reduction efficiency at water temperature of 25℃, biofilm density of 45%, organic loading of 4.0 kg COD/(m3 filler·d), supply quantum of 150 L/h and the oxygenate mode of batch aeration of 30 min/stop of 30 min with a square wave changing supply quantum. When carbon source was glucose, the average sludge yield was the lowest, 0.0292 kg MLSS/(kg COD·d), comparing with that of other carbon sources, which was on average 19.4%, 64.8% and 99.9% less than that of the manure, sodium acetate and starch, respectively. And the concentrations of effluent COD, NH4+ -N and TN were 41, 6.4 and 17.3 mg/L, respectively, when the carbon source was glucose.
