Abstract
The present invention relates to mud concentrated dehydration treatment equipment for mud generated in sewage containing oil in an oil field. The equipment solves the problem of vicious circle of environment pollution and impurity in a water treatment system caused by mud external discharge. The equipment is characterized in that after a sewerage recovery pond (1) is communicated with settlement separate devices (2 and 3) in parallel, the sewerage recovery pond (1) is connected with a mud concentration pot (8), a mud storage tank (11) and a dehydrator (13) through a mud lifting pump (4) and a flow meter (14). The dehydrator (13), a supernatant liquid water discharge pipe of the mud concentration pot (8) and an oil outlet pipe of the mud concentration pot (8) are respectively connected with the recovery pond (1) and a slop tank (12). The secondary pollution of water quality and vicious circle of impurity in a sewage treatment process are avoided, the environment is protected, and simultaneously, the sewage treatment efficiency and the water quality of effluent water are enhanced.
Description
(1) technical field:
The device that the mud that the present invention relates to produce in the oil-contaminated water of oil field is handled belongs to mud concentrated dehydration treatment equipment.
(2) background technology:
Present progressively going deep into along with oil-field development, the waste of sewage and mud constantly increases, composition is more complicated also, and give sewage disposal, re-injection and efflux and cause very big harm, no matter be the oily water treatment of polymer flooding, ternary composite oil-displacing or conventional water drive extraction.Oil-water mixture is through handling as the coagulant precipitation jar 15 of Fig. 2 and the thickening of natural subsidence jar 16 mostly, the filtration that oil-water mixture after make handling enters continuous quadratic hay tank 7 through the lifting of surge tank 17, pump 18, isolated water is recovered in the pond for recovering 1, but all there is the problem of spoil disposal in this.And in order to guarantee the water quality of water outlet, in a large number through slurry tank (15,16) water-containing sludge after sedimentation is handled need regularly efflux the outer sewage lagoon that arrives at a station, environment is polluted, moreover efflux a large amount of impurity that dammed in the process at water-containing sludge, Sewage treatment systems is returned in these impurity such as untimely processing, certainly will cause the vicious cycle of mud impurity in Sewage treatment systems, not only increase the intractability of sewage, influenced effluent quality, even the adverse consequences on the stratum that can result in blockage.So need to stop production the settled impurity of periodic cleaning, waste great amount of manpower and material resources and financial resources.
(3) summary of the invention:
Technical problem to be solved by this invention is that mud effluxes the environmental pollution that causes and the problem of the vicious cycle of impurity in water treatment system.
Adoptable technical scheme is: this mud concentrated dehydration treatment equipment, comprise sewage pond for recovering, hay tank and clear water jar, the sewage pond for recovering is taken into account line mixer connection mud concentration tank by mud first lift pump, first flow after being communicated with settlement separate equipment, efficient settlement separate equipment side by side successively, and concentration tank is by continuous successively storage mud jar of second lift pump, second under meter and water extracter; Water extracter, concentration tank supernatant liquor water shoot and concentration tank oil outlet pipe connect pond for recovering and slop oil tank respectively again, the concentration tank clear water water inlet pipe clear water jar that links to each other; Chemicals dosing plant links to each other with the inlet end of line mixer, and efficient settlement separate equipment is communicated with the back with the water side of hay tank and links to each other with the inlet end of line mixer.
The beneficial effect of this device is: because oil-water mixture enters into concentration tank, storage mud jar and water extracter after entering settlement separate device processes, the water that makes concentration cross is recycled in the pond for recovering, avoids the secondary pollution and the vicious cycle of impurity in sewage treatment process of water quality; And mud reaches the outward transport of requirement index after treatment; avoided mud not treated and only after the sedimentation periodic cleaning efflux and the environmental pollution that causes; protected environment; also reduced simultaneously the expense that increases as the water filling water source with the clear water of measuring of replenishing; sewage treating efficiency and effluent quality have been improved; a large amount of human and material resources and financial resources are saved in the cleaning that also need not stop production.
(4) description of drawings:
Accompanying drawing 1 process flow sheet of the present invention;
Accompanying drawing 2 is process flow sheets that prior art is handled.
1-sewage pond for recovering, the settlement separate equipment of 2-, the efficient settlement separate equipment of 3-, 4-first lift pump, 4 '-the second lift pump, 5-line mixer, 6-chemicals dosing plant, 7-hay tank, the 8-concentration tank, 9-backwashing pump, 10-clear water jar, 11-storage mud jar, 12-slop oil tank, 13-water extracter, 14-first flow meter, 14 '-the second flow agent, 15-coagulant precipitation jar, 16-natural subsidence jar, 17-surge tank, 18-pump.
(5) embodiment:
Below with the present invention is further illustrated:
As Fig. 2 in conjunction with shown in Figure 1, this mud concentrated dehydration treatment equipment, comprise sewage pond for recovering 1, hay tank 7 and clear water jar 10, connect mud concentration tanks 8 by mud first lift pump 4, first flow meter 14 and line mixer 5 successively behind the settlement separate equipment 2 of sewage pond for recovering 1 connection arranged side by side, the efficient settlement separate equipment 3, and concentration tank 8 is by continuous successively mud jar 11 and the water extracter 13 of storing up of second lift pump 4 ', second under meter 14 '; Water extracter 13, concentration tank 8 supernatant liquor water shoots and concentration tank 8 oil outlet pipes connect pond for recovering 1 and slop oil tank 12 respectively again, the concentration tank 8 clear water water inlet pipes clear water jar 10 that links to each other; Chemicals dosing plant 6 links to each other with the inlet end of line mixer 5, and efficient settlement separate equipment 3 is communicated with the back with the water side of hay tank 7 and links to each other with the inlet end of line mixer 5.Hay tank 7 connection traffic meters 14, backwashing pump 9 backs are connected with clear water jar 10.
When entering into, oil-water mixture (about water ratio 99.5%) is driven in the concentration tank 8 by lift pump 4 after settlement separate equipment 2 is handled, this moment, under meter 14 write down the quantity of mixed solution, mixed solution carries out mud at concentration tank 8 and concentrates quiescent settling, dwindled sludge volume widely, oil come-up in the mud enters into 12 li of slop oil tanks by oil outlet, makes that sump oil obtains reclaiming, can utilize once more, turn waste into wealth; The liquid of middle part then is recovered in the pond for recovering 1 by water outlet; Mud then sinks to concentration tank 8 bottoms, be driven into (water ratio about 90% this moment) in the storage mud jar 11 by lift pump 4, the mud of this moment is got to lift pump 4 and is carried out processed in the water extracter 13, the water that extrudes is recovered in the pond for recovering 1, the mud water ratio that extrudes reaches the outward transport of requirement index and gets final product about 40%.
As seen, the water that concentration is crossed is recycled in the pond for recovering 1, avoids the secondary pollution and the vicious cycle of impurity in sewage treatment process of water quality; And mud reaches the outward transport of requirement index after treatment; avoided mud not treated and only after the sedimentation periodic cleaning efflux and the environmental pollution that causes; protected environment; also reduced simultaneously the expense that increases as the water filling water source with the clear water of measuring of replenishing; sewage treating efficiency and effluent quality have been improved; a large amount of human and material resources and financial resources are saved in the cleaning that also need not stop production.
