Detailed Description
In order to make the technical solution of the present invention better understood, embodiments of the present invention are described in detail below with reference to the accompanying drawings.
In connection with the description of figure 1,
a multi-stage oil separation tank comprises a tank body 1, the tank body is generally a cuboid, the tank body is a cuboid of 10m × 4m × 4m in the embodiment, a water inlet 2 and a water outlet 3 are respectively arranged at two ends of the tank body, and the multi-stage oil separation tank further comprises partition plates 4, in the embodiment, the number of the partition plates is two, the tank body is divided into multi-stage treatment tanks by the partition plates, the multi-stage treatment tanks comprise a first-stage treatment tank 5, a second-stage treatment tank 6 and a third-stage treatment tank 7, the number of the partition plates can be increased or decreased according to the size of the tank body, and a; still include cobble permeable bed 9, in this embodiment, the cobble permeable bed sets up wherein primary treatment pond and secondary treatment pond, and the cobble permeable bed also can only set up in primary treatment pond certainly, and oily waste water process the cobble permeable bed 9 slows down waste water velocity and makes oil molecule collision formation oil droplet surfacing fast, and water also can down flow simultaneously.
Referring to fig. 1, the cell body divide into first order treatment pond 5, second grade treatment pond 6 and third grade treatment pond 7, and first order treatment pond top contains water inlet 2, and oily waste water passes through first order treatment pond 5, second grade treatment pond 6 and third grade treatment pond 7 in proper order, then discharges outside the cell body 1 through delivery port 3, in this embodiment, the cobble permeable bed sets up wherein first order treatment pond and second grade treatment pond.
In this embodiment, referring to fig. 1, the longitudinal sections of the pebble permeable layers of the first-stage treatment tank 5 and the second-stage treatment tank 6 are right triangles, the lowest end of the inclined surface of the pebble permeable layer of the first-stage treatment tank is connected to the bottom of the tank body, and the highest end of the inclined surface of the pebble permeable layer of the first-stage treatment tank is connected to the partition plate to form an inclined upstream surface, and the inclined surface of the pebble permeable layer of the second-stage treatment tank is opposite to the inclined surface of the pebble permeable layer of the first-stage treatment tank in the inclined direction. So set up, waste water comes in from the water inlet and directly falls on the upstream face on the cobble permeable bed in first order treatment pond, because the water hole of crossing that the baffle was kept away from to the upstream face slope setting and upstream face least significant end, waste water flows through the speed of crossing the water hole to further slowing down and can the high-speed collision formation oil droplet float out the surface of water. The purpose that the upstream face of the pebble permeable layer of the second-stage treatment pool and the upstream face of the first-stage treatment pool are opposite is that the wastewater flows to the second-stage treatment pool through the water passing hole, so that the wastewater can flow to the next-stage treatment pool and the floating of the residual oil stain can be accelerated.
Furthermore, in order to further slow down the flow speed of the wastewater and accelerate the floating of the wastewater oil stain, pebbles 10 are arranged inside the water through holes 8.
As a multistage oil interceptor, in order to further slow down the waste water velocity of flow to can be abundant accomodate the greasy dirt, the first stage treatment pond should have sufficient volume, should be half of multistage oil interceptor total volume generally.
Further, as an implementable mode, still include baffle 11, the baffle is established at second level treatment pond 6, the baffle sets up perpendicularly and the highest point is located 6 middle parts in second level treatment pond, the baffle setting is mainly in second level treatment pond improvement second level oil interceptor treatment effeciency, the baffle highest point is located second level treatment pond middle part can slow down the velocity of flow of water and make the greasy dirt of the aquatic entrainment that flows into second pond separate once more, make the greasy dirt float out the surface of water, sewage then crosses the water hole from second level treatment bottom of the pool and stays the tertiary treatment pond, the tertiary treatment pond main function is manger plate and drainage.
In the embodiment, the oil-well pump 12 is further included, the number of the oil-well pumps is set according to the actual situation, and the oil-well pumps are arranged above the first-stage treatment tank 5 and the second-stage treatment tank 6 in the implementation, it should be noted that in other embodiments, the oil-well pumps are not arranged in the second-stage treatment tank because oil-containing dirt is little, the oil pump pumps the oil dirt at the top of the multi-stage treatment tank out of the tank body, and the oil dirt floating out of the water surface can be pumped out by the oil-well pumps; when the oil on the water surface is less, the oil can be collected and treated by the oil absorption felt.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
