Utility model content
The utility model its object is to provide a kind of waste water advanced pre-treatment oil trap, and the waste water quality before effective raising Sewage advanced treatment, avoids the deficiency such as Sewage advanced treatment ultra-filtration membrane, reverse osmosis membrane well damage.
For realizing the utility model object, the technical scheme of employing is:
A kind of waste water advanced pre-treatment oil trap, comprise cylinder body, the water-in of cylinder body and water outlet, it is characterized in that: in described cylinder body, be provided with several baffle plates, cylinder body is divided into several point of pond by each baffle plate, each baffle plate is provided with filtering net, be provided with sewage draining exit bottom each point of pond, the casing wall in each point of pond is provided with oil discharge outlet; Be provided with pH meter in cylinder body, cylinder body is configured with lift pump, and the water outlet of cylinder body is provided with by-pass valve control.
Further, described cylinder body and baffle plate are steel plate, can withstand shocks, the advantage such as high strength, adaptation severe environment.
Further, described cylinder body and baffle plate are provided with preservative coat, are conducive to avoiding the materials such as greasy dirt to cylinder body and baffle plate corrosion, improve cylinder body and baffle plate work-ing life.
Further, the filtering net staggered arrangement in described adjacent screen, is conducive to increasing waste water in a point pond residence time, fully makes the water in waste water be separated with oil, other foreign material.
Further, described lift pump is engineering plastic pump, and erosion resistance is better, increases lift pump work-ing life.
Further, point pond of filter opening size from point pond of inlet end to water outlet end for described filtering net reduces successively, effectively avoids filtering net to block, and improves the water quality of filtered wastewater.
Further, described filtering net is steel wire filtering net, has erosion resistance strong, the features such as long service life.
The beneficial effects of the utility model:
One, closed by water outlet by-pass valve control when water oil-containing, utilize greasy dirt and water not to dissolve each other, oil and the density weight difference opposite sex of water, in flow process, discharge the greasy dirt oil floated up on the water surface from oil discharge outlet, improve waste water quality.
Two, when the waste water after multiple points of pond process is still too high by pH meter detection pH value, or when waste water quality is still muddy, extract waste water out oil trap by lift pump, avoid the process of waste water penetration depth to bring loss, thus ensure the waste water quality entering Sewage advanced treatment.
Three, each point of pond is provided with filtering net, filters macrobead foreign material, improve waste water quality; By being provided with sewage draining exit bottom each point of pond, during easy cleaning, be used for draining blowdown.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of waste water advanced pre-treatment oil trap.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
A kind of waste water advanced pre-treatment oil trap as shown in Figure 1, comprise: cylinder body 1, baffle plate 2, filtering net 3, oil discharge outlet 4, sewage draining exit 5, pH meter 7, lift pump 8, water outlet 6 and water-in 9, several baffle plates 2 are provided with in described cylinder body 1, cylinder body 1 is divided into several point of pond by each baffle plate 2, each baffle plate 2 is provided with filtering net 3, be provided with sewage draining exit 5 bottom each point of pond, the casing wall in each point of pond be provided with oil discharge outlet 4; Be provided with pH meter 7 in cylinder body 1, cylinder body 1 is configured with lift pump 8, and the water outlet 6 of cylinder body 1 is provided with by-pass valve control.
Baffle plate 2 is arranged in cylinder body 1, can be equidistant arrangement, also can non-equidistant arrange, and perpendicular to being in contact with it each of cylinder body 1, also can being in contact with it cylinder body 1 wall and forming the various arrangement mode such as acute angle or obtuse angle.
This water-in 9 adopts square elbow, and water inlet direction, perpendicular to bottom point pond, avoids waste water to advantages such as the direct impacts of baffle plate 2.
This pH meter 7 is arranged in point pond of last process waste water, is conducive to observing that raw wastewater entered that several points of ponds are filtered, precipitated, pH value after oil extraction, if exceeded standard, discharge waste water by lift pump 8, do not exceed standard, advanced waste treatment system processes further to waste water.
This cylinder body 1 and baffle plate 2 are steel plate, can withstand shocks, the advantage such as high strength, adaptation severe environment.
This cylinder body 1 and baffle plate 2 are provided with preservative coat, and preservative coat is preferably antifouling paint, are conducive to avoiding the materials such as greasy dirt to corrode cylinder body 1 and baffle plate 8, improve cylinder body 1 and baffle plate 2 work-ing life.
Filtering net 3 staggered arrangement in this adjacent screen 2, concrete staggered arrangement mode: the plane that baffle plate 2 installs filtering net 3 is baffle plate mounting face, adjacent head net 3 is projected in that can stagger for left and right in the position of baffle plate mounting face, the multiple staggered arrangement mode such as stagger up and down, be conducive to increasing waste water in a point pond residence time, fully make the water in waste water be separated with oil, other foreign material.
This lift pump 8 is engineering plastic pump, and erosion resistance is better, increases lift pump 8 work-ing life.
This filtering net 3 is steel wire filtering net, has erosion resistance strong, the features such as long service life.
Point pond of filter opening size from point pond of inlet end to water outlet end for filtering net 3 described in this reduces successively, effectively avoids filtering net 3 to block, and improves the water quality of filtered wastewater.Some filtering net 3 filter opening unifications are excessive can not filter little particle foreign material, and the unification of its filter opening is too small or arrangement regulation is not right, filtering net 3 all can be caused to block, can not reach filter effect.
Closed by water outlet 6 by-pass valve control when water oil-containing, utilize greasy dirt and water not to dissolve each other, oil and the density weight difference opposite sex of water, in flow process, discharge the greasy dirt floated up on water surface oil from oil discharge outlet 4, improve waste water quality.
It is still too high that waste water after multiple points of ponds process detects pH value by pH meter 7, or when waste water quality is still muddy, extract waste water out oil trap by lift pump 8, avoid the process of waste water penetration depth to bring loss, thus ensure the waste water quality entering Sewage advanced treatment.
Each point of pond is provided with filtering net 3, filters macrobead foreign material, improve waste water quality; By being provided with sewage draining exit 5 bottom each point of pond, during easy cleaning, be used for draining blowdown.
By waste water advanced pre-treatment oil trap to after Wastewater Pretreatment, enter advanced waste treatment system process waste water again, the filter core usage quantity of Sewage advanced treatment is reduced by more than 50, extends ultra-filtration membrane, reverse osmosis membrane at least half a year in work-ing life, the successful obtained.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
