摘要: 选用固硫灰渣深度处理经生化处理后焦化废水，采用分光光度计法评价焦化废水的处理效果，采用XRD、XRF、SEM和IR等分析材料的成分、结构和微观形貌等。结果表明,固硫灰渣用量60 g/L、吸附时间15 min，焦化废水的脱色率可达94.22%，COD 从原水的76.01 mg/L降低到处理后的5.76 mg/L，NH+4-N从1.09 mg/L降低到处理后的0.62 mg/L，色度从320倍降低到小于5倍，均大大低于国家一级排放标准要求的含量。处理后固硫灰渣经300℃焙烧活化后循环处理焦化废水，表明经循环利用6次后仍表现出很好的处理效果。

Abstract: Fluidized bed combustion(FBC) ashes were used to advanced treat the biochemistry pretreated coking wastewater. UV-Visible spectrophotometer was used to estimate the removal efficiency of contamination from the coking wastewater. The component, structure and morphology of the material were characterized by X-ray diffraction (XRD), X-ray fluorescence spectrometer (XRF), scanning electron microscopy (SEM) and fourier transform infrared spectroscopy (FTIR).The results show that when the dosage of sorbent is 60 g/L and absorption time is 15 min, the decoloration rate of coking wastewater reaches to 94.22%, COD, NH+4-N and chroma of the wastewater decline from 76.01 mg/L, 1.09 mg/L and 320 times to 5.76 mg/L, 0.62 mg/L and less than 5 times, respectively. After absorption, the sorbent was activated calcined and recycled to deal with the coking wastewater. The results show that the decoloration effect of sorbent is well after six recycle times.
