摘　　要：采油废水中硫酸盐还原菌（SRB）所造成的注水系统的腐蚀、结垢和阻塞严重影响着原油的开发与生产。催化电解杀菌技术用于油田废水处理，利用废水中的Cl-产生的活性氯对杀菌起主要作用，杀菌效果好。催化电解杀灭SRB的试验结果表明，在电流密度25mA／cm2、极板间距2cm、pH值4～9的电解条件下处理30min时SRB杀菌率达99％以上。Nanometer Fe3O4 was prepared by hydrothermal method, and its adsorption performance for dye wastewater was studied. The magnetic Fe3O4 was used as an adsorbent to remove acid red in aqueous solution, and the spectrophotometry was used to test the adsorption results. Effects of pH value, amount of Fe304 material and other factors on the adsorption were investigated, the optimal elution conditions was also determined. The results show that, under optimal adsorption conditions, the removal rate of acid red can reach to 94.7%.
