Description
Technical field
Technical field of sewage is the utility model is related to, in particular to a kind of sanitary sewage pretreatment system.
Background technology
Caused sewage during human lives, is one of primary pollution source of water body, including wash water and kitchen
Sewage etc., in kitchen sewage, substantial amounts of greasy dirt and dish slag etc. are contained, wherein, greasy dirt generally swims in the water surface, and dish slag
In composition, it is different according to density, suspended state or precipitated form are presented in water.For ease of the subsequent treatment of sewage, generally
Need to pre-process kitchen sewage, greasy dirt and dish slag in removal sewage etc..
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How a kind of energy is provided
It is enough that preliminary treatment, simple in construction, lower-cost sanitary sewage pretreatment system are carried out to sanitary sewage.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of sanitary sewage pretreatment system, it is characterised in that including from high to low be in step-like setting sedimentation basin and
Filler pond, the sedimentation basin are provided with water inlet away from the side in the filler pond, and towards the filler pond side to set
The overflow wall of overfall is equipped with, the middle part of the sedimentation basin has the dividing plate of setting parallel with the overflow wall, the dividing plate
The bottom interval of lower end and the sedimentation basin set to form hydrospace, the upper end of the dividing plate is higher than the sedimentation basin；Institute
State and granular activated carbon is filled with filler pond；The upper end of the overflow wall is also equipped with the screen pack set along its length,
The length of the screen pack is consistent with the length of the overflow wall；Also include the collecting-tank for being used for temporary processing water, it is described to catchment
The bottom in pond is connected with the bottom in the filler pond.
Using said structure, using step-like setting, gravity can be utilized sewage is flowed from high to low, sewage is from entering
After the mouth of a river enters sedimentation basin, under the stop of dividing plate, sedimentation basin can only be flowed into by the hydrospace of crossing between dividing plate and bottom of pond
Opposite side, because the greasy dirt in sewage and floating object are located at top layer mostly, it becomes possible to which the greasy dirt in sewage and floating object are entered
The row first step is cleared up；Overfall is set on the overflow wall of sedimentation basin so that sewage can only be overflowed to from overflow coping and filled out
In material pond, the larger dirt of water Midst density sinks under water, and can not enter filler pond by overfall, can filter most of precipitation
Thing.Screen pack is installed on overflow wall, suspension in sewage can be filtered, can be with finally by the absorption of activated carbon
Complete the preliminary treatment to sewage.Because the oil slick in sewage first passes through partition wall isolation so that screen pack will not be by excessive oil
Dirt adhesion, be advantageous to improve the service life and filter effect of screen pack.Said structure, it is right using the characteristic of dirty impurities in water
Floating object and sediment are purged, simple in construction, and cost is relatively low.
Further, multiple dismountable net cages are provided with the filler pond, the granular activated carbon is filled in described
In net cage.
Using said structure, because net cage is detachable, granular activated carbon is filled in net cage, facilitates activated carbon more
Change.
Further, the screen pack is made using stainless steel.
So, the service life of screen pack can be extended.
Further, the top of the screen pack is higher than the sedimentation basin, and is tilted along away from the direction in the filler pond
Set.
So, preferably the suspension in water can be filtered out, avoids suspension from being overflowed from the top of screen pack.
In summary, the utility model, which has, to carry out preliminary treatment to sanitary sewage, and simple in construction, cost is relatively low,
The advantages that treatment effect is preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
With reference to embodiment, the utility model is described in further detail.
During specific implementation：As shown in figure 1, a kind of sanitary sewage pretreatment system, including be in step-like setting from high to low
Sedimentation basin 1 and filler pond 2, the sedimentation basin 1 is provided with water inlet away from the side in the filler pond 2, and is filled out towards described
The side of material pond 2 is the overflow wall for being provided with overfall, and the middle part of the sedimentation basin 1 has setting parallel with the overflow wall
Dividing plate 12, the bottom interval of the lower end of the dividing plate 12 and the sedimentation basin 1 sets to form hydrospace, the dividing plate 12
Upper end is higher than the sedimentation basin 1；Granular activated carbon is filled with the filler pond 2；The upper end of the overflow wall is also equipped with edge
The screen pack 4 that its length direction is set, the length of the screen pack 4 are consistent with the length of the overflow wall；Also include being used for temporarily
The collecting-tank 3 of processing water is deposited, the bottom of the collecting-tank 3 is connected with the bottom in the filler pond 2.
Using said structure, using step-like setting, gravity can be utilized sewage is flowed from high to low, sewage is from entering
After the mouth of a river enters sedimentation basin, under the stop of dividing plate, sedimentation basin can only be flowed into by the hydrospace of crossing between dividing plate and bottom of pond
Opposite side, because the greasy dirt in sewage and floating object are located at top layer mostly, it becomes possible to which the greasy dirt in sewage and floating object are entered
The row first step is cleared up；Overfall is set on the overflow wall of sedimentation basin so that sewage can only be overflowed to from overflow coping and filled out
