  • 摘要: 以一种新型可降解材料PLA/PHBV共混物为碳源和生物膜载体,对硝酸盐污染水进行反硝化脱氮。在温度为(29±1)℃,pH为(7.5±0.2)条件下,利用响应曲面法考察了进水硝态氮浓度、水力停留时间(HRT)和出水硝态氮浓度之间的关系,建立了以出水硝态氮浓度为响应值的二次多项式回归模型,模型预测值与实验值能很好吻合。方差分析结果表明,进水硝态氮浓度和HRT及其交互作用对响应值均具有显著性影响(P<0.01)。
    Abstract: PLA/PHBV blend, a new kind of biodegradable polymer, was used as carbon source and biofilm support to remove nitrate from contaminated water. The relationship of the effluent and influent nitrate-nitrogen concentrations and hydraulic retention time (HRT) was quantitatively investigated using response surface methodology at (29±1)℃ and pH (7.5±0.2). A polynomial regression model was developed with the effluent nitrate-nitrogen concentration as response value. The calculated values of the model agreed well with the experimental data. Influent nitrate-nitrogen concentration, HRT and their interaction had significant impacts on the response value by analysis of variance (P<0.01).
