【摘要】 针对钻井过程中产生大量污水直接排入采油厂污水站,造成污水处理不达标的问题,通过实验,提出了化学混凝沉降法和化学混凝沉降+氧化还原法两种钻井污水处理工艺技术,经现场处理试验,能有效解决钻井污水处理问题。更多还原

【Abstract】 Large amount of sewage produced during drilling operation are directly drained into the sewage plant of Oil Recovery Plant, resulting in that the sewage treatment can not meet the requirements. Two technologies are developed for treating the sewage produced during drilling operation through experiments. Field application shows that these two technologies can effectively treat drilling sewage.更多还原
