Description
Technical field
The utility model relates to the oil-contained waste water treatment device of the oily(waste)water that a kind of city oily(waste)water, oil production and petrochemical industry refining industry produce in process of production.
Background technology
At present, a large amount of oily(waste)waters of producing in process of production of city oily(waste)water (as automobile making, service station, carwash industry) and oil production and petrochemical industry refining industry need to handle (as oil recovered water, refinery circulating sewage etc.).The degreasing technique of domestic present employing and method have following several:
1, gravity coagulant precipitation (adding water purification agent cooperates);
2, pressure coagulant precipitation (adding water purification agent cooperates);
3, air-float technology technology (physics method);
4, eddy flow Technology (physics method);
5, water quality modification (chemical method).
In the above-mentioned several method, on technology and cost performance angle, it is better that air supporting and cyclone technique are handled the oily(waste)water effect.But present most of device is owing to problems such as structure designs, and the water after the processing is difficult to reach country or industry specified standards, need throw in chemical agents such as water purification agent to some extent.
The several problems that exist are gone up in air-floating apparatus design at present
1. there is not the dividing plate step-by-step design in the treatment trough
All to be that sewage is enterprising go out down or a left side is entered the right side and gone out in the design of general treatment trough, and the centre does not have staging treating, and is simple in structure, cheap, but often the water quality of the oily(waste)water after the processing is difficult to up to standard.Reason is when oil-containing surpasses 300mg/l, suspended substance above 100mg/l, be mixed with a large amount of oil and suspended substance in the sewage, and small bubble (diameter 30 μ m) can't hold up so many oil clot come-up gatherings, even increase the dissolved air water amount again, can not deal with problems, thereby cause oil removing and suspended substance weak effect, this is one of bad reason of air flotation effect.
2 treatment troughs do not have middle deoiling filler design
In the air flotation slot design, the swash plate oil removal treatment is adopted in general only consideration at front end sewage inlet place, but the treatment trough of back is not taken measures.When sewage with oil was high, though can make 60～80% oil come-up by the air supporting means, also remaining 20～40% oil-containing was not removed, be air flotation effect bad former therefore two.
3 dissolved air waters mix uneven with oily(waste)water
General dissolved air water is sent into the bottom of separator tank by a pipeline, and the perforate by the tube head part discharges the interior oily(waste)water of dissolved air water and groove and mix release (aeration), and takes oil droplet by small bubbles and float to the water surface.Because oily(waste)water is fast into and out of concentrated flow speed, and the dissolved air water that discharges can only affact part of contaminated water, apparent, such mixing is uneven, this be air flotation effect bad former therefore three.
Eventually the above, air supporting and eddy flow are the technology of comparative maturity, but in the device structure of handling oily(waste)water and technological design, there is weak point, make air flotation technology can not perform to best effect, general oil removal efficiency has only about 90%, to add reverse-phase emulsifier simultaneously, thereby the cost of disposing of sewage is increased.
The utility model content
The purpose of this utility model is to adopt pressurized dissolved air flotation oil removing (suspended substance) and filler coalescent deoiling (machine is mixed) principle, designs a kind of comprehensive physics oil removing system.
Oil-contained waste water treatment device described in the utility model is by pretreatment tank, four parts of first and second air supporting treatment trough and water outlet dashpot are formed, pretreatment tank is positioned at the front portion of treatment unit, by-level is provided with the oil removing dividing plate that has aperture above two in the groove, the place is provided with collection tube at water-oil interface, be connected with oil sump by pipeline, a swirler respectively is equipped with at the place at the gentle water inlet of oily(waste)water import, establish two rising pipes at trench bottom, rising pipe is connected with groove header tank outward, is provided with the regulating pondage plate in the header tank; After one time the air supporting treatment trough is positioned at pretreatment tank, the oily(waste)water import of groove is connected with the pressure air-dissolving water inlet pipe with the outlet of header tank, be provided with one deck sinusoidal deoiling filler in the middle of in the groove, a mixing swirler is housed above groove central filler layer, trench bottom is established four rising pipes, rising pipe is connected with groove header tank outward, is provided with the regulating pondage plate in the header tank; After secondary air supporting treatment trough was positioned at air supporting treatment trough, the oily(waste)water import was connected with the pressure air-dissolving water inlet pipe with the outlet of header tank, was provided with one deck sinusoidal deoiling filler in the middle of in the groove, and a mixing swirler is housed above groove central filler layer; After the water outlet dashpot was positioned at secondary air supporting treatment trough, trench bottom was connected with the air water ingress of pretreatment tank with Airfloat pump by pipeline; First and second air supporting treatment trough bottom is connected with the collection mud sump.
When oily(waste)water enters treatment unit, feed a certain amount of gas-liquid mixture simultaneously, after entering oil-water separation tank, gas expansion in the gas-liquid mixture forms a large amount of small bubbles (diameter is about 30 μ m) and carries on part oil droplet and the suspended substance and floats to the water surface, remaining oil and suspended substance enter the sinusoidal filler downwards with sewage, oil droplet is through collision repeatedly in moving process, friction, assemble, (diameter＞25 μ m) back is carried by small bubbles and is floated to the water surface after the elaioleucite diameter increases to a certain degree, deliver in the oil sump thereby be collected, suspended substance (machine is assorted) then is deposited on the treatment trough bottom and delivers in the dirty pond of collection.
