Abstract
The invention provides a comprehensive sewage treatment all-in-one machine. The comprehensive sewage treatment all-in-one machine comprises a sewage collecting tank, a shell-and tube mixed reaction device, a pressure dissolved air flotation device, a hydraulic automatic filter device, a clean water tank and other devices. With the adoption of the comprehensive sewage treatment all-in-one machine, the corrosion of sewage to equipment is lowered; the operation cost of equipment is decreased; the energy consumption is reduced; only a lift pump and a dissolved air pump need electric traction, while other devices are mostly in traction under the effects of hydraulic pressure and gravity to achieve the operation standard, so that the production cost is also greatly reduced, and the drained water meets national drainage standard.
Description
Technical field
The invention belongs to field of Environment Protection, be specifically related to a kind of composite wastewater and process all-in-one.
Background technology
At present, the oilfield exploitation of China is still in stage of steady development, in recovery process, due to the restriction of technology, natural condition, make to have stayed in recovery process huge water body resource, this class water often oil-containing and solid impurity higher, if can not effectively process, will cause great lot of water resources waste.Therefore, oily water separation technique is just very crucial, and conventional oil-water separation method is settling process, By Bubble-floating Method, filtration method, centrifuging etc.But light uses above-mentioned a certain specific method, in the time processing water body, effect is not often very desirable, particularly stratum production fluid, this class water body water-based changes greatly, and sewage viscosity increases, reduced oil droplet buoyance lift speed, oil droplet particle attenuates little, and emulsification degree increases, is difficult to coalescence; Suspended substance individual particles attenuates little, and stability strengthens, and settling character variation is suspended state in water, is difficult to separate.In addition, if above-mentioned traditional technology is processed successively, can cause again equipment to take up an area large, consume energy high, production cost is also enhanced thereupon.Therefore, design and develop a kind of composite wastewater and process all-in-one, can collect the advantage of above-mentioned treatment process, the problems such as occupation of land, energy consumption that can solve again seem very necessary.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provide a kind of composite wastewater to process all-in-one.
Technical scheme: in order to achieve the above object, the present invention specifically completes like this: composite wastewater is processed all-in-one, comprise a sewage collecting basin, described sewage collecting basin bottom is provided with sewage pump, this sewage pump is by the tubular-mix reaction unit of falling in lines of the sewage transport in sewage collecting basin, between sewage pump and shell and tube mixed reactor, be connected with No. one chemicals dosing plant, in the intermediate conduit of shell and tube mixed reactor, be connected with chemicals dosing plant No. two; Shell and tube mixed reactor is connected with air flotation device of pressure air-dissolved by pipeline, is provided with Oil and slag scraping machine at air flotation device of pressure air-dissolved top, and Residual oil residue in Oil and slag scraping machine is discharged by coupled oil extraction residue extraction machine; In air flotation device of pressure air-dissolved inside, and be positioned at the Oil and slag scraping machine back lower place and be provided with one group of integrated form inclined plate sedimentation device, this integrated form inclined plate sedimentation device and horizontal plane acutangulate, and vertically opposite with the mechanical dredge machine of air flotation device of pressure air-dissolved bottom; Face at Oil and slag scraping machine on the sidewall of air flotation device of pressure air-dissolved and be provided with air flotation pool shore pipe; Air flotation device of pressure air-dissolved regulates pressure by pressure volume pot, and pressure volume pot is braked by air compressor; The sewage flowing out from air flotation device of pressure air-dissolved flows into clean water basin filtering by hydraulic automatism strainer, is equipped with automatic back-washing device between hydraulic automatism strainer and clean water basin; Clean water basin inside is provided with dissolved air water pump, by this dissolved air water pump, a part of clear water is imported to pressure volume pot kinetic energy is provided, and another part clear water is directly discharged from clean water basin.
Wherein, preferably described integrated form inclined plate sedimentation device and horizontal plane angle are 45～60 °.
Wherein, in hydraulic automatism strainer, be provided with roundabout flap, lengthened current distance and further improved filter effect.
Wherein, described air flotation pool shore pipe and integrated form inclined plate sedimentation device bottom is extended and is connected, and is convenient to macrobead in settler directly from swash plate landing to shore pipe.
Beneficial effect: compared with conventional art, the present invention has reduced the corrosion of sewage to equipment; Reduce the running cost of equipment, reduced the consume of the energy, owing to only having lift pump and air dissolved pump to need electric traction, and other devices mostly reach operation standard by waterpower and gravity, greatly reduced production cost, the water body of discharge can reach discharging standards.
