  • 摘要: 以净水污泥制备的柱状颗粒为载体，采用上流式曝气生物滤柱（BAF）对污水厂经厌氧处理后的印染废水进行好氧处理。通过对净水污泥柱状颗粒的破碎实验、热重分析、BET、EDX、XRD、SEM和ICP-AES等表征分析表明，制备净水污泥柱状颗粒载体的最佳焙烧温度为600℃。在BAF对污染物的去除过程中，并且结构稳定。研究了COD、NH3-N、色度和SS等生化特性随BAF高度的沿程变化情况以及水力负荷、气水比对BAF处理效能的影响。结果表明，在气水比为4：1、水力负荷为0.03~0.06 m3·（m2·h）-1的最优条件下，BAF对COD、NH3-N、色度及SS的去除分别集中在填料层60 cm以下、60 cm以下、45 cm以上及15 cm以上。
    Abstract: Dyeing wastewater pretreated with an anaerobic process was aerobically treated using an up-flow biological aerated filter (BAF) column, which is a carrier for water purification sludge (WPS) particles prepared through granulation and calcinations. The WPS particles were characterized by a crushing test, thermogravimetric analysis, a BET-specific surface area test, an energy dispersive X-ray fluorescence spectrometer, X-ray diffraction, a scanning electron microscope, and inductively coupled plasma-atomic emission spectrometry, and the results revealed that the optimal calcination temperature was 600℃. The WPS carriers did not release secondary pollutants, such as heavy metals, and their granular structure was retained during the BAF wastewater treatment process. The removal rates of COD, NH3-N, chroma, and SS were investigated along with the optimal BAF height for each. The effects of hydraulic loading and air-water ratio on the efficiency of the BAF were also studied in detail, and their optimal values were from 0.03 to 0.06 m3·(m2·h)-1 and 4:1, respectively. The effective height of the BAF for the removal of COD and NH3-N was below 60 cm, whereas it was 15 cm and above 45 cm for the removal of SS and chroma, respectively.
