  • 摘要: 厨余发酵液中含有丰富的VFA、乳酸等快速降解有机物,以及碳水化合物、蛋白质等慢速降解的有机物,利用厨余发酵液作为外增碳源强化生物脱氮的可行性。首先利用SBR处理投加厨余发酵液后的低C/N污水,经过40 d的培养,最终TN去除率稳定在85%左右,出水COD低于40 mg/L,说明厨余发酵液具有强化生物脱氮的能力;然后利用批式实验研究其在不同C/N条件下的反硝化规律,发现当C/N≤5.1时,出水出现了NO2--N积累现象,C/N升高到最佳的6.5时,NO2--N积累现象消失,反硝化速率为3.77 mg NO3--N/(g VSS·h)。
    Abstract: Fermentation liquid of food waste consisted of large amount of readily (VFA, lactate) and slowly (carbohydrate, protein) biodegradable organic substances. In this study, the feasibility of using fermentation liquid of food waste as external carbon to improve nitrogen removal was investigated. Firstly, SBR was used to treat low C/N ratio wastewater with the addition of fermentation liquid as external carbon. After 40 days' acclimatization, nitrogen removal rate reached 85% and COD concentration in the effluent was below 40 mg/L, which demonstrated that adding fermentation liquid of food waste obviously enhanced nitrogen removal efficiency. Then, the characteristics of denitrification were studied by batch experiments. It was found that nitrite accumulation occurred when C/N ratio was lower than 5.1, while it disappeared as C/N ratio increased to 6.5. At this optimum C/N ratio of 6.5, denitrification rate was 3.77 mg NO3--N/(g VSS·h).
