含聚含油污水处理剂BHQ-402的评价

A Treatment Agent BHQ-402 Used for Wastewater Containing Polymer and Oil

LD10．1油田含聚合油污水处理回注是提高该油田开发效果的重要保障，采用新型高效非离子型清水剂BHQ-402，研究不同加量、搅拌转速、搅拌速度、搅拌时间等因素对处理效果的影响。结果表明：先用水稀释BHQ-402药剂至质量分数为1％，在BHQ．402加量500mg／L、搅拌速度200--400r／min、搅拌时间2-3min下．除油净化效果好，除油率最高可达83．69％，去浊率最高可达92．74％；BHQ-402用乙醇溶解再用水稀释后配制为质量分数为1％溶液，在加量为200mg／L、搅拌速度400r／min、搅拌时间3min的条件下，除油率≥87％，去浊率≥92％，加药量少，处理后的水质指标大幅度提高。

Dealing with the polymer flooding sewage and injection to the stratum in LD10-1 oilfield is the important guarantee for developing of the oilfield, using a nonionic purifying agent BHQ-402, the treatment effect of the dosage, stirring speed, stirring time and other factors were investigated. The results showed that, when the BHQ-402 was diluted to mass fraction of 1% with fresh water, the degreasing and cleansing effect was good at the BHQ-402 amount of 500 mg/L, pharmacy reaction of 200---400 r/min, and stirring time of 2--3 rain. Oil removal rate was up to 83.69%, and turbidity removal rate was as high as 92.74%.When the BHQ-402 was first dissolved with ethyl alcohol, then diluted to mass fraction of 1% with fresh water, and the BHQ-402 amount was 200 mg/L, stirring speed was 400 r/min and stirring time was 3 min, the degreasing rate was greater than or equal to 87%, and the turbid rate was greater than or equal to 92%. The BHQ-402 addition amount was less, while the treated water quality indicators were increased greatly.
