Description
Technical field
The utility model relates to a kind of waste disposal plant, particularly a kind of well-drilling waste water flocculation sediment treatment unit.
Background technology
In the process of oilfield drilling, the waste water that the 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, well-drilling waste water have a little many, wide, pollutant kind is complicated, high stability, intermittent discharging and discharging characteristics such as difficult control, is petroleum industry 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 that its organic biodegradability is poor, pollutent mainly contain following several:
(1) CODcr: from various organic sludge treatment agents and tensio-active agent such as tannin, pore forming material and defoamer etc.;
(2) oil: from oil-base mud, diesel coolant, drilling unit wash-down water etc.;
(3) heavy metal: mainly by the Cr6+ that adds inorganic treatment additive chromic salt introducing, 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 usually, process well-drilling waste water, 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 ", large for flowability, cycle is short, waste water quality changes well-drilling waste water greatly, usually adopt flocculation, sedimentation, filter, the modes such as absorption are processed, be the disclosed well-drilling waste water treatment process of 201010209919.3 Chinese invention patent " treatment process of the poly-sulphur mud drilling waste water of a kind of deep-well " such as application number, by flocculation, and be aided with adsorption and oxidation technique the impurity in the well-drilling waste water is more efficiently removed.

There is following weak point usually in the existing device that utilizes flocculence to process well-drilling waste water:
1, the flocculation agent use-pattern is generally to the wastewater disposal basin of storage 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, flocculation agent and well-drilling waste water reaction times are longer, and have the inadequate problem of reaction.
2, when adding such as low solubility flocculation agents such as white limes, because its solubleness is low, usually need add excessive flocculation agent, a large amount of flocculation agents are deposited in the wastewater disposal basin, have both caused the flocculation agent waste, have taken again the wastewater disposal basin pond and have held.
3, owing to the soluble material that contains in the well-drilling waste water than multipolarity, only adopting conventional flocculation agent to process well-drilling waste water is difficult to the pollutent in the waste water and colourity are effectively processed, well-drilling waste water after the processing can not satisfy the requirement of wellbore construction, can not reuse.
