  • 摘要: 为实现有限碳源的最大化利用,在厌氧/限氧曝气序批式生物系统的基础上,以碳源偏低的模拟城市污水为对象,分析比较厌氧阶段典型周期内不同碳源浓度,总磷浓度对聚-β-羟基丁酸酯(PHB)积累的影响,并考察了运用新的前曝气模式对PHB积累的影响。结果表明,当碳源浓度为140、280和400 mg/L时,PHB积累的最大值分别为10.53、22.75 和32.61 mg/g;当总磷浓度为6、12和18 mg/L时,PHB最大积累值分别为25.75、32.54和38.27 mg/g。说明进水碳源浓度和总磷浓度与PHB的最大积累量呈正相关,且碳源浓度对PHB积累量的影响比总磷浓度的影响大。比较无前曝气时厌氧PHB最大积累量,前曝气时间为10、20和30 min的最大积累量分别增长了25.1%、57.1%和69.5%,说明增设前曝气运行方式有利于PHB的积累。
    Abstract: To achieve the optimization use of the limited carbon source, taking simulated municipal wastewater for object under low carbon-source condition, the effects of COD and TP concentrations on poly-β-hydroxybutyrate (PHB) accumulation were analyzed and compared in anaerobic/limit oxygen sequencing batch reactor, as well the influence of PHB accumulation applying in the pre-aeration pattern was also studied.The results showed that the maximum of PHB accumulation are 10.53 mg/g, 22.75 mg/g and 32.61 mg/g when the concentrations of carbon source are 140 mg/L, 280 mg/L and 400 mg/L, respectively.When TP concentrations are 6 mg/L, 12 mg/L, and 18 mg/L, the max PHB accumulation perform 25.75 mg/g, 32.54 mg/g and 38.27 mg/g respectively.It is illustrated that there is a positive correlation between the max PHB accumulation and inflow concentrations of carbon source and TP, and it is more critical for carbon source to work on the max PHB accumulation than TP does.Comparing to the treatment without pre-aeration, the PHB maximum accumulation quantity after pre-aeration increase by 25.1%, 57.1%, 69.5% as aeration times are 10 min, 20 min and 30 min, respectively.It demonstrates that pre-aeration treatment helps to the accumulation of PHB.
