A Study On The Technology Of Oily Waste Water Treatment Of Double Swirl

In Daqing oilfield oily waste water treatment process is the traditional "natural sedimentation, coagulation and sedimentation, filtration pressure" process for processing.The process there are treatment process is long, covers an area of large, one-time investment is high, breeding bacteria, sludge treatment is not perfect wait for serious problem,Therefore,through the development of the field test, and strive to explore a new way of the treatment of oil containing sewage containing polymer, preferably a streamlined, efficient polymer containing oily waste water treatment process.Through the site to carry out double swirl flow combined oil removing device test, select the depth of sewage water, sewage station filtered water, raw water, sewage treatment station of back washing water and other 4 kinds of water quality to carry out technical tests, carried out at the same time dosing, sterilization, sludge treatment and other auxiliary system test,impact test and field operation parameters determination. After a period of production operation, the filtered water to oil layer of low permeability reservoir water quality standard.Through the efficient treatment process for field test of Double Swirl oily sewage, open up a new path for polymer containing sewage treatment, which can provide reference for oily waste water treatment technology of oilfield. For oily sewage treatment, improve the filtered water quality to provide a strong guarantee.
