JZ9-3油田含聚采油污水粘度高、稳定性强,严重影响到现场污水处理流程和设备的运行。为解决这一问题,通过对JZ9-3油田污水处理流程和单元设备的模拟,进行了现场3种净水剂和不同含聚量的含油污水对斜管除油器、气浮选器和过滤器的影响研究。阳离子型净水剂BHQ-203和ICA的除油效果较阴离子型净水剂BHQ-08的除油效果好,能起吸附电中和及架桥作用,斜管除油器处理不同含聚含油污水后其含油量由263.2 mg/L下降到20.73 mg/L,气浮选器的除油率9%～34%,过滤器在进水含油较低(<50 mg/L)的情况下,起到强化除油的作用;含聚量增加,过滤后悬浮物量呈下降趋势,过滤困难,含聚量达到一定值(>600 mg/L)后无法分析悬浮物量;斜管除油器、气浮选器和过滤器出口水样的ζ电位值在-22.5～-42 mV,随含聚量的增加而变小,污水稳定性增加。研究结果用以指导现场工艺设备的改造。
JZ9-3 oilfield contains poly-oil sewage has high viscosity and strong stability, seriously affecting the on-site sewage treatment process and equipment operation. To solve this problem, through the simulation of the sewage treatment process and unit equipment of JZ9-3 oilfield, three kinds of water purifying agents and oil-containing wastewater with different content of polycondensation were carried out on inclined pipe degreaser, air flotation device and filtration Research on the Impact of Devices. Cationic water purifying agent BHQ-203 and ICA degreasing effect than the anionic water purifying agent BHQ-08 degreasing effect is good, can play the role of adsorption and bridge bridging pipe degreaser with different containing oil After the sewage, the oil content decreased from 263.2 mg / L to 20.73 mg / L, the degreasing rate of the flotation device was 9% ~ 34%. When the filter had a low oil content (<50 mg / L) The content of suspended solids decreased after filtration, the filtration was difficult, the amount of suspended solids can not be analyzed after the concentration reaches a certain value (> 600 mg / L); inclined tube degreaser, gas The zeta potential of flotation device and filter outlet was -22.5 ~ -42 mV, which decreased with the increase of the content of aggregates, and the stability of wastewater increased. The results are used to guide the transformation of on-site process equipment.
