活性炭吸附法处理淀粉废水的试验研究

[目的]探讨活性炭吸附处理淀粉废水的最佳条件。[方法]采用活性炭吸附法处理低浓度马铃薯淀粉废水,分别研究了吸附时间、活性炭粒径及用量、废水pH及温度对淀粉废水处理效果的影响。[结果]当活性炭粒径为40目,用量为5 g,吸附时间为1 h,废水温度为27℃,pH为5时,活性炭对马铃薯淀粉废水的吸附效率最高达48%。[结论]该研究为淀粉废水的有效处理提供了理论参考。

Study on Treatment of Potato Starch Wastewater Through Activated Carbon Adsorption

[Objective] The study aimed to discuss the optimal conditions for treatment of potato starch wastewater through activated carbon adsorption.[Method] Low-concentration potato starch wastewater was treated by activated carbon,and the influences of adsorption time,particle size and dosage of activated carbon,wastewater pH and temperature on its treatment effect were analyzed.[Result]When 5 g of activated carbon with the particle size of 40 mesh was added to potato starch wastewater（pH = 5） to absorb organic matter for 1 h at 27 ℃,the adsorption efficiency of activated carbon was the highest,about 48%.[Conclusion] The research could provide scientific references for the effective treatment of starch wastewater.
