Description

A kind of oilfield sewage oil removal sand removal sedimenting system
Technical field
This utility model belongs to disposing polluted water in oil technical field, is specifically related to a kind of oilfield sewage oil removal sand removal sedimentation and is System.
Background technology
Existing oil-bearing wastewater relies on three grades of Sedimentation tank oil removings and settling sand removing, and after sedimentation, sewage processes through water and sets Standby filtration injection oil reservoir up to standard.Sewage enters low-level culture pool and has little time to settle oil removing, directly enters two grades even three grades by inclined hole Sedimentation tank, the sedimentation time is short, the weak effect of sedimentation oil removing, after a large amount of oil-polluted waters enter water treatment facilities, mud and oil emulsion It is enriched in fine filtration device surface (fibrous nodules or sintered pipes), damages fine filtering apparatus, cause serious economic loss.
Utility model content
The purpose of this utility model is to provide a kind of oilfield sewage oil removal sand removal sedimenting system, solves existing oilfield sewage The problem settling the weak effect of oil removing in process.
This utility model be employed technical scheme comprise that, a kind of oilfield sewage oil removal sand removal sedimenting system, including connecting successively Connect unloads pond, Sedimentation tank, oil separation grit chamber and water purification collecting pit, and the bottom of oil separation grit chamber connects collection mud sump, collects mud sump Inside it is provided with sludge lifting pump a, sludge lifting pump a to be connected to outside oil separation grit chamber by pipeline, the exit of oil separation grit chamber Arranging downflow weir and adjustable for height oil baffle, the inwall of oil separation grit chamber connects collection tube line, and collection tube line sinks with oil removal Oil sump outside sand pond connects, and the bottom of water purification collecting pit is provided with sewage pump b and liquid level alarm.
Feature of the present utility model also resides in,
The junction of oil separation grit chamber and water purification collecting pit is near downflow weir.
Oil baffle and downflow weir are close to oil separation grit chamber top.
Collection tube line is near the top of oil separation grit chamber.
The bottom of oil separation grit chamber is inclined-plane, and collection mud sump is positioned at the low spot bottom oil separation grit chamber.
Collection tube line is connected with the inwall of oil separation grit chamber by support and pipe clamp.
The beneficial effects of the utility model are: a kind of oilfield sewage oil removal sand removal sedimenting system is by arranging oil removal sand setting Pond, the bottom of oil separation grit chamber is inclined-plane, and under action of gravity, silt particle deposits in the low point set mud sump of slope along inclined-plane, in collection mud sump Silt particle cleaning is periodically pulled to neighbouring multi-purpose station by tank car and processes by sludge lifting pump a, and the exit of oil separation grit chamber arranges overflow Weir and adjustable for height oil baffle, after oil baffle stops, sump oil floats, in collection tube line enters oil sump, it is achieved sump oil silt particle Extend the sewage sedimentation time while cleaning, settle the effective of oil removing, improve oil removing sand settling function, it is ensured that after process, water quality reaches Mark.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of oilfield sewage oil removal sand removal sedimenting system.
In figure, 1. unload pond, 2. Sedimentation tank, 3. oil separation grit chamber, 4. water purification collecting pit, 5. inclined-plane, 6. collection mud sump, 7. dirty Mud elevator pump a, 8. support, 9. oil baffle, 10. downflow weir, 11. sewage pump b, 12. liquid level alarms, 13. collection tube lines, 14. oil sumps.
Detailed description of the invention
