Description

technical field

[0001] The invention belongs to the field of sewage treatment devices, and in particular relates to an oil scraping device for sewage treatment. Background technique

[0002] At present, most of the sewage treatment of new refineries in my country adopts grease traps, flotation tanks and aeration tanks. The key equipment of this sewage treatment process is: oil scraper and mud scraper, foam scraper and aeration machinery. There are two methods of oil separation, one is inclined plate oil separation, and the other is advection oil separation, which mainly removes oil droplets with a particle size of 100-105 microns or more and removes sludge. The operation of the advection type grease trap is relatively stable and reliable. Domestic transportation has mature experience. Timely oil collection and regular mud discharge are powerful measures to ensure the normal operation of the advection type grease trap. Taking an oil refinery with an annual crude oil process...
