The utility model comprises a biochemical tank with a waste water inlet, wherein the water outlet tube of the biochemical tank is connected with an air floatation tank via a pipeline, the outlet of the air floatation tank via a pipeline is connected with the inlet of an oxidization tank whose outlet via a pipeline is connected with the inlet of a sand filter tank, and the oxidization tank is provided with a water outlet. The treatment device can destroy the gel system of slurry waste water of drill well to break gel and destabilize, can remove the organic pollutant partly in waste water, and absorb the solid suspensions of waste water most via active slurry. The treatment device can reach primary discharge stand of national GB8978-1996.
Description
Technical field
The utility model relates to a kind of wastewater treatment equipment, is particularly suitable for the processing integrated apparatus of oil and gas well drilling waste water
Background technology
Oil and gas well drilling waste water is the mixed pollutants of the collection mud that produces in the drilling process, water, dispersion agent, oils etc., its colourity height, and the turbidity height, the concentration of suspension height, and be the high stability colloidal solution of dispersion system.In the treating processes of well-drilling waste water, it surely is its crucial technology that the broken glue of colloidal solution takes off.
What the past generally adopted is that the broken glue of chemistry takes off steady method, promptly adopts and adds the colloidal stability that oxygenant destroys waste water.The shortcoming of this technology is the cost height, not having ubiquity is that a kind of oxygenant can not be general in various well-drilling waste waters, but also having increased new pollutent, the waste water after the processing still can not reach the first discharge standard of national GB8978-1996 again after technical finesses such as chemical flocculation, solid-liquid separation, chemical oxidation, filtration.Patent of invention as notification number CN1405101 " a kind of improvement method of waste mud-slurry of oil-field well-drilling " discloses the above-mentioned method that well-drilling waste water is handled of carrying out that adopts.
The utility model content
Technical problem to be solved in the utility model provides a kind of treatment unit that can adopt biochemical technology to handle drilling mud waste water.
The drilling mud wastewater treatment equipment that technical problem adopted that the utility model solves, comprise the biochemistry pool that is provided with the waste water import, the rising pipe and the air flotation pool of above-mentioned biochemistry pool pass through pipe connection, pipe connection is passed through in the outlet of above-mentioned air flotation pool and the import of oxidation pond, the outlet of above-mentioned oxidation pond is connected with the import of sand filter by pipeline, and above-mentioned oxidation pond is provided with water outlet.
As improvement of the present utility model, aerator is installed in the bottom of biochemistry pool.
Further improve as of the present utility model, air compressor is installed in the bottom of air flotation pool.
Adopt treatment unit of the present utility model, can not only destroy the colloidal dispersion of drilling mud waste water, reach brokenly glue and take off steady purpose, and can remove the part organic pollutant in the waste water, the suspended solid major part in the waste water is adsorbed by active sludge.Chemical flocculation is passed through in water outlet again, solid-liquid separation, and chemical oxidation just can guarantee to reach discharging standards GB8978-1996 first discharge standard after the technical finesses such as filtration.
Active sludge in the biochemistry pool will be moved to next and handle a use, not discharge, and therefore can not produce secondary pollution.The mud that coagulation produces is by solid-liquid separation, and its water ratio is low, can be not by dehydration directly and well drilling detritus in the lump by the effect solidification treatment of solidifying agent, can not produce secondary pollution to environment.

Mark among the figure: the 1-biochemistry pool, the 2-air flotation pool, the 3-oxidation pond, the 4-sand filter, the import of 5-waste water, the 6-aerator, the 7-pipeline, the 8-pump, the 9-air compressor, the 10-water outlet, the 11-flocculation agent adds inlet.
Embodiment
Drilling mud wastewater treatment equipment of the present utility model, as shown in Figure 1, comprise the biochemistry pool that is provided with the waste water import, the rising pipe and the air flotation pool of above-mentioned biochemistry pool pass through pipe connection, pipe connection is passed through in the outlet of above-mentioned air flotation pool and the import of oxidation pond, the outlet of above-mentioned oxidation pond is connected with the import of sand filter by pipeline, and above-mentioned oxidation pond is provided with water outlet.
Drilling mud waste water is injected biochemistry pool 1 by waste water import 5, in biochemistry pool, add simultaneously active sludge, aerobic bacteria and yeast, after the aeration that was undertaken 30～40 hours by aerator 6 is handled, COD has reduced by 60～70%, suspended solid has reduced by 50～60%, mud waste water has lost colloidal stability, realizes coming unstuck.Be transported to the air flotation pool 2 by pipeline 7 with the outlet of pump 8 through the waste water of handling that comes unstuck at biochemistry pool 1 from biochemistry pool 1 top, simultaneously in order in air flotation pool 2, to realize the solid-liquid separation in the waste water better, pipeline 7 is provided with flocculation agent and adds inlet 11, and adds the aluminium based flocculating agent.In the bottom of air flotation pool 2 air compressor 9 is installed, helps the solid-liquid separation in the air flotation pool 2.Air compressor 9 feeds pressurized air, realizes solid-liquid separation, removes petroleum substance.As add the aluminium based flocculating agent of waste water total amount 0.6～0.8%, aeration handle 1～1.5 hour just can be with mud-water separation.Through the waste water of solid-liquid separation from the top of air flotation pool 2 by pipe-line transportation to oxidation pond 3, and enter from the bottom of oxidation pond 3.Handle through oxygenant oxidations such as 5～8 hours clorox or hydrogen peroxide in oxidation pond 3, the waste water COD after the processing is between 80-100.Will be through the waste water of handling in the oxidation pond 3, from the outlet on oxidation pond 3 tops through pipe-line transportation to the sand filter 4 through 5～10 minutes precipitation, discharge the processing waste water that meets the GB8978-1996 first discharge standard from water outlet 10.
