Abstract
The utility model discloses an oil well sewage treatment device, which comprises a sewage pool and a filter cartridge arranged in a sewage pool sunken pit, wherein the filter cartridge is composed of a primary filter net, a secondary filter net and a triple filter net having the same net diameters, the secondary filter net is sleeved in the primary filter net, the triple filter net is sleeved in the secondary filter net, a first filter layer made of fiber ball filter material is arranged between the primary filter net and the secondary filter net, a second filter made of fiber ball filter material is arranged between the secondary filter net and the triple filter net, and the thickness of the first filter layer is greater than that of the second filter layer. The impurities in the sewage can be filtered for a plurality of times so as to effectively remove the impurities.
Description
Technical field
The utility model relates to petroleum drilling technology field, relates in particular to a kind of device for treatment of oil-well sewage.
Background technology
At present, oil drilling industry is a high pollution industry, in the sewage producing, contain the pollutants such as clay, organic polymer, drilling cuttings and drilling fluid additive in drilling process, must could discharge as other or directly after treatment, otherwise will surrounding enviroment and underground water source be caused to very serious pollution.
In order to address the above problem, following technology is proposed in prior art:
As China Patent No. " 201020121789.3 " discloses a kind of oil drilling sewage treatment recycling device, its open day is on December 15th, 2010, this sewage-treatment plant is mainly by cesspool, cartridge filter, immersible pump, water tank with go out water pump and form, and cesspool is by the rectangular tank of Plate Welding; There is cesspool water inlet pipe in one end of cesspool, there is circular depressed hole in the bottom of the cesspool other end, in depression hole, establish cylindrical cartridge filter, in cartridge filter, hang and be fixed with immersible pump, the outlet pipe of immersible pump connects the water tank of a Plate Welding, and in the bottom of water tank, delivery port is connected with out water pump.But in actual use,, cartridge filter can only filter the impurity that external diameter is greater than three grades of filter screen mesh internal diameters, and can not filter the impurity (as the class impurity etc. that swims) that external diameter is less than three grades of filter screen mesh internal diameters, causes wastewater treatment efficiency poor.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of device for treatment of oil-well sewage is provided, and the utility model can carry out multiple times of filtration to the impurity in sewage, effectively removes the impurity in sewage.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of device for treatment of oil-well sewage, it is characterized in that: comprise cesspool and be arranged on the cartridge filter in cesspool depression hole, described cartridge filter is by netting the identical single filter net in footpath, cascade filtration net and three-stage filtration net composition, described cascade filtration net is located in one group of screen pack, described three-stage filtration net is located in cascade filtration net, between described single filter net and cascade filtration net, be provided with the first filter course of being made by fiber-ball filter media, between described cascade filtration net and three-stage filtration net, be provided with the second filter course of being made by fiber-ball filter media, and the thickness of the first filter course is greater than the thickness of the second filter course.
On the outer surface of described single filter net, be provided with the 3rd filter course.
Described filter course is fixed in cartridge filter by silk screen.
Employing the utility model has the advantage of:
One, in the utility model, the filter course of being made up of fiber-ball filter media has advantages of light weight, intensity is high, physical and chemical performance is stable, between durable in use, filler space be difficult for by biomembrane stop up, active strong and treatment effect is good, therefore the first filter course and the second filter course are set on cartridge filter, and the first filter course thickness is greater than the structure of the first filter course thickness, can be to the filtration that repeatedly misplaces of the impurity in sewage, effectively prevent that the impurity in sewage from entering cartridge filter, significantly improved the filter effect of sewage.
Two, in the utility model, be provided with the 3rd filter course on the outer surface of described single filter net, this structure has further been strengthened the filter effect of sewage.
Three, in the utility model, described filter course is fixed in cartridge filter by silk screen, and this structure is convenient to change at any time or clear up filter course, makes it remain best filter effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1, cesspool, 2, cartridge filter, 3, the first filter course, 4, the second filter course, 5, the 3rd filter course.
The specific embodiment
A kind of device for treatment of oil-well sewage, comprise cesspool 1 and be arranged on the cartridge filter 2 in cesspool 1 depression hole, described cartridge filter 2 is by the identical single filter net in net footpath, cascade filtration net and three-stage filtration net composition, described cascade filtration net is located in one group of screen pack, described three-stage filtration net is located in cascade filtration net, between described single filter net and cascade filtration net, be provided with the first filter course 3 of being made by fiber-ball filter media, between described cascade filtration net and three-stage filtration net, be provided with the second filter course 4 of being made by fiber-ball filter media, on the outer surface of described single filter net, be provided with the 3rd filter course 5, described filter course is fixed in cartridge filter 2 by silk screen, and the thickness of the first filter course 3 is greater than the thickness of the second filter course 4.
In the utility model, the sewage that enters cesspool 1 arrives cartridge filter 2 internal layers through the 3rd filter course 5, single filter net, the first filter course 3, cascade filtration net and the second filter course 4 successively, the first filter course 3, the second filter course 4 and the 3rd filter course 5 intermediate gap Heterogeneous Permutations, by multiple times of filtration, can effectively remove the impurity in sewage.
