摘要
发酵米糠可用于处理工业废水中Cr(Ⅵ)。研究了发酵米糠的浓度、溶液温度、pH值、Cr(Ⅵ)的浓度、处理时间等因素对发酵米糠处理Cr(Ⅵ)效果的影响。对于浓度低于40mg/L的Cr(Ⅵ)溶液,在60℃、pH值为2条件下,用10g/L发酵米糠处理40min,Cr(Ⅵ)去除率可达95.7%。
The fermented rice bran may be used to treat the Cr(Ⅵ)in wastewater. The effects of the dosage of fermented rice bran, temperature, pH, concentration of Cr(Ⅵ), and time on the treatment of Cr(Ⅵ)were investigated. The results showed that, under the conditions of fermented rice bran at 10 g/L, 60 ℃, and pH=2, 95.7% of the Cr(Ⅵ)in less than 40 mg/L can be removed within 40 min.
