Abstract

The development in technology and industrial activities has lead to release of various metal ions to the environment. The present study aims to assess the efficiency of Rice Husk in treating chromium (VI) from simulated wastewater, with the help of fixed-bed adsorption column by performing continuous adsorption experiment. The results obtained through this study were confirmed by developing a model. A detailed analysis on the effects of extensive parameters on the adsorption experiment was done. The extensive parameters considered were Concentration, Flow-rate, and Bed-height. It was observed that as flowrate decreased from 60 ml/min to 30ml/min, the breakthrough time also decreased from 30 to 20 min. whereas as when the concentration was increased from 250 mg/L to 1000 mg/, the breakthrough time came down to 10 min fro m 40 min. The parameters which were calculated were total percentage removal of Cr (VI) and breakthrough time. It was observed that the exhaustion time decreases with increase in the concentration and flow rate and it increases with bed height. The data obtained during the entire experiment were fitted in Thomas and Yoon Nelson Model. The values of the model parameters were evaluated and analyzed.

废水中铬的脱除突破曲线建模
科技和工业活动的发展导致各种金属离子释放到环境中。本研究利用固定床吸附柱进行连续吸附实验,考察稻壳对模拟废水中六价铬的处理效果。通过建立模型验证了本研究的结果。详细分析了各种参数对吸附实验的影响。广泛考虑的参数有浓度、流速和床层高度。结果表明,当流速从60 ml/min降低到30ml/min时,突破时间从30 min缩短到20 min,当浓度从250 mg/L增加到1000 mg/L时,突破时间从40 min缩短到10 min。计算了Cr (VI)的总去除率和突破时间。随着浓度和流量的增加,衰竭时间减小,随着床层高度的增加,衰竭时间增大。整个实验过程中得到的数据用Thomas和Yoon Nelson模型进行拟合。对模型参数的取值进行了评价和分析。
