Description
Technical field
The present invention relates to a kind of waste disposal plant and sewage water treatment method, especially a kind of well-drilling waste water flocculation sediment treatment unit and utilize the method for this apparatus processes waste water.
Background technology
In the process of oilfield drilling, the waste water that mud during owing to tripping operation on the seepage of the loss of mud, mud circulating system, flushing uphole equipment and the drilling tool and greasy dirt form is called well-drilling waste water.Well-drilling waste water is the important source of pollution of petroleum prospecting enterprise, and characteristics such as that well-drilling waste water has is a little many, wide, pollutant kind is complicated, high stability, intermittent discharging and the difficult control of discharging are petroleum industries than one of water pollution source of unmanageable and disposal.
Well-drilling waste water contains the various ingredients in the mud; Form complicated; Principal pollutant have suspended substance, heavy metal, oil, phenol, sulfide etc.; Well-drilling waste water totally has the colourity height, suspension content is high, the CODcr value is high, the characteristics of its organic biodegradability difference, and pollutent mainly contains following several kinds:
(1) CODcr: from various organic sludge treatment agents and tensio-active agent such as tannin, pore forming material and skimmer etc.;
(2) oil: from oil-base mud, diesel coolant, drilling unit wash-down water etc.;
(3) heavy metal: mainly by adding the Cr6+ that inorganic treatment additive chromic salt is introduced, the chromic salt ligninsulfonate is also introduced chromium ion in addition, and other source of heavy metal pollution also has Pb2+, Cd2+ plasma.
Prior art adopts the mode of flocculation to purify, handle well-drilling waste water usually; See also the 387th page～390 pages disclosed documents " well-drilling waste water and acid fracturing operation wastewater Processing Technology Research progress " on December 25th, 2002 " oilfield chemistry "; Short, waste water quality of, cycle big to flowability changes well-drilling waste water greatly; Usually adopt modes such as flocculation, sedimentation, filtration, absorption to handle; Like application number is 201010209919.3 the disclosed well-drilling waste water treatment process of Chinese invention patent " a kind of deep-well gathers sulphur DWM wastewater treatment method ", through flocculation and be aided with absorption and oxidizing process is more efficiently removed the impurity in the well-drilling waste water.
The research that recycles after handling for well-drilling waste water at present still belongs to blank at home; Being used to join slurry after well-drilling waste water is handled is the main application of well-drilling waste water; The slurry water is joined in drilling well does not at present still have national standard, requires chroma in waste water to need less than 300, to the CODcr no requirement (NR) during wellbore construction.Because D.D. is dark more, the well-drilling waste water amount of generation is big more, contains a large amount of suspended substances and oily substance in the waste water; Colourity is greater than 5000; Waste water COD cr10000～40000mg/L, and good stability, the mud-water separation difficulty; Cause the considerable part sewage can not reuse, must build enough ponds and store drilling waste water.
There is following weak point usually in the existing device that utilizes flocculence to handle well-drilling waste water:
1, the flocculation agent use-pattern is generally to the wastewater disposal basin of storing well-drilling waste water and directly adds flocculation agent; Well-drilling waste water and flocculation agent react in wastewater disposal basin; Because wastewater disposal basin is built at situ of drilling well temporarily; Whipping appts is not installed usually, and flocculation agent and well-drilling waste water reaction times are longer, and have the inadequate problem of reaction.
2, when adding like low solubility flocculation agents such as white limes, because its solubleness is low, need add excessive flocculation agent usually, a large amount of flocculation agents are deposited in the wastewater disposal basin, have both caused the flocculation agent waste, have taken the wastewater disposal basin pond again and have held.
3, owing to contain more polar soluble material in the well-drilling waste water; Only adopting conventional flocculation agent to handle well-drilling waste water is difficult to pollutants in waste water and colourity are effectively handled; Well-drilling waste water after the processing can not satisfy the requirement of wellbore construction, can not reuse.
The storage pool of revising when 4, fld is handled well-drilling waste water in the drilling well phase at present need take a large amount of surrounding grounds, causes the project cost of land too high, and the sewage environmental pollution of storage has a big risk.
