| 摘 要： | 通过将玉米淀粉与氢氧化钠、三氯化铝和无水碳酸钠在恒温磁力搅拌器上搅拌、加热,使得玉米淀粉改性,制得改性淀粉絮凝剂,并研究了改性淀粉絮凝剂对含油废水的处理效果.试验结果显示,在搅拌速度与时间分别为快搅速度200 r/min,快搅时间0.5 min;慢搅速度100 r/min,慢搅时间3 min的情况下,使用改性淀粉絮凝剂处理含油废水时,COD去除率为77.94%、石油类去除率为61.2%、透光率为62.7%、SS去除率为79.96%;最佳反应条件为:投药量为12 mg/L、温度为5~30℃、pH值为6-8.

| Abstract: | A modified starch flocculant is made and the results of using it for the oil wastewater treatment have been studied.The results show that,when the fast stirring speed is 200r/min,the fast stirring time is 30s,the slow stirring speed is 100 r/min and the slow stirring time is 3min respectively,the remove rate of COD,oil,light crossing,and SS is 77.94%,61.2%,62.7%,79.96%,respectively;and the optimum reaction condition of the modified starch flocculant is:the optimum providing amount is 12mg/L,the optimum temp... |
