| 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. |
