  • 摘要: 将水华鱼腥藻附着固定在改性的弹性聚氯乙烯载体表面形成藻类生物膜,用于研究其脱氮除磷动力学过程。保持氮磷比约为11:1,配制NH4+-N和PO43--P初始浓度变化范围分别为4.31~229.91和1.70~69.15 mg/L的模拟废水,在废水pH为6.8~7.2、室温、光照强度3 500 lx、连续光照条件下培养藻类生物膜,利用Michaelis-Menten模型测定产率系数Y、反应速率常数k与半饱和常数Km。结果显示,藻类生物膜对氮、磷的去除速率随着营养物质浓度的升高而增加;与磷相比,藻类生物膜对氮的利用效率更高。藻类生物膜脱氮除磷动力学系数分别为:① N:Y = 0.72(mg/m2 chla)/(mg/L NH4+-N),k=1.24 (mg/L NH4+-N)/((mg/m2 chla)·d),Km=17.88 mg/L;② P:Y = 2.50(mg/m2 chla)/(mg/L PO43--P),k=0.35 (mg/L PO43--P)/(mg/m2 chla)/d,Km=7.29 mg/L。
    Abstract: Algal biofilms were prepared by Anabaena flos-aquae attached on the surface of modified flexible polyvinyl chloride (PVC) carriers.The biokinetic process of nitrogen and phosphorus removal was studied.The NH4+-N concentration was varied between 4.31~229.91 mg/L while PO43--P concentration was between 1.70~69.15 mg/L by keeping N/P ratio around 11:1 in the synthetic wastewater.The experiments were performed at pH 6.8~7.2 and at room temperature with continuous artificial illumination (3 500 lx).The biokinetic coefficients were determined such as reaction rate constant (k), half saturation constant (Km) and yield coefficient (Y) by using Michaelis-Menten rate expression.Results indicated that nutrient removal efficiencies increased with increasing nutrient concentrations and algal biofilms could remove nitrogen more effectively compared to phosphorus.Biokinetic coefficients were determined as Y=0.72(mg/m2 chla)/ (mg/L NH4+-N), k=1.24 (mg/L NH4+-N)/(mg/m2 chla)/d, Km=17.88 mg/L for nitrogen and Y= 2.50(mg/m2 chla)/ (mg/L PO43--P), k=0.35 (mg/L PO43--P)/(mg/m2 chla)/d, Km=7.29 mg/L for phosphorus.

摘要: 将水华鱼腥藻附着固定在改性的弹性聚氯乙烯载体表面形成藻类生物膜,用于研究其脱氮除磷动力学过程。保持氮磷比约为11:1,配制NH4+-N和PO43--P初始浓度变化范围分别为4.31~229.91和1.70~69.15 mg/L的模拟废水,在废水pH为6.8~7.2、室温、光照强度3 500 lx、连续光照条件下培养藻类生物膜,利用Michaelis-Menten模型测定产率系数Y、反应速率常数k与半饱和常数Km。结果显示,藻类生物膜对氮、磷的去除速率随着营养物质浓度的升高而增加;与磷相比,藻类生物膜对氮的利用效率更高。藻类生物膜脱氮除磷动力学系数分别为:① N:Y = 0.72(mg/m2 chla)/(mg/L NH4+-N),k=1.24 (mg/L NH4+-N)/((mg/m2 chla)·d),Km=17.88 mg/L;② P:Y = 2.50(mg/m2 chla)/(mg/L PO43--P),k=0.35 (mg/L PO43--P)/(mg/m2 chla)/d,Km=7.29 mg/L。
