Description
Technical field
The utility model relates to civil engineering structure field, sewage, specifically a kind of BAF construction structure integrated with sand filter.
Background technology
In advanced treatment of wastewater, BAF its go out water suspension and sometimes exceed standard, need to carry out filtering basin process again, the head loss of BAF is larger, there is 2 ~ 3m head loss, have gas, water backwashing measure, be equipped with backwash pump, back flushing air purge blower fan etc.The head loss of sand filter is also comparatively large, has 2 ~ 2.5m head loss, has gas, water backwashing measure, be equipped with backwash pump, back flushing air purge blower fan etc.
Water flows to sand filter from BAF, and its water level elevation difference is comparatively large, and basic two process structures are separate, and due to the back flushing water yield, the hydraulic pressure difference of two processing units, especially hydraulic pressure is different; Air purge air quantity, blast are different, and the backwash pump that two structures are equipped with, air purge blower fan are independent mutually, and it takes up an area comparatively large, and be equipped with utility appliance more, investment is large, runs loaded down with trivial details simultaneously.
Utility model content the purpose of this utility model is to provide a kind of BAF construction structure integrated with sand filter, to solve prior art Problems existing.
In order to achieve the above object, the technical scheme that the utility model adopts is:
BAF construction structure integrated with sand filter, it is characterized in that: include clean water basin, BAF and sand filter, BAF and sand filter are built jointly as adjacent organic structures, pool wall between BAF with sand filter arranges the channel being communicated with effluent of aeration biological filter mouth and sand filter water-in, also comprise BAF, the air purge blower fan that sand filter shares, backwash pump, described air purge blower fan air outlet by total air purge airduct respectively with BAF, sand filter is communicated with, described backwash pump water-in is communicated with clean water basin, backwash pump water outlet by total backwash water pipe respectively with BAF, sand filter is communicated with, described sand filter upper water-out mouth is communicated with clean water basin by pipeline.
Described BAF construction structure integrated with sand filter, it is characterized in that: described air purge blower fan is provided with manual modulation valve, tensimeter successively on the air purge airduct of sand filter, described backwash pump is also provided with manual modulation valve, tensimeter on the backwash water pipe of sand filter.
Described BAF construction structure integrated with sand filter, it is characterized in that: in described BAF and sand filter, be divided into some lattice respectively, and effective Filter length of every lattice is corresponding identical with width with effective Filter length of lattice every in sand filter with width in BAF, in BAF and sand filter, every lattice form identical filtration area.
The pond body of BAF and sand filter is built jointly by the utility model, only every a pool wall, saves and takes up an area, convenient management; Through arranging tensimeter and variable valve, the backwash water pump of BAF, backwash blower fan and sand filtration are shared, invest little, floor space is little, runs and controls simply.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Figure 1, BAF construction structure integrated with sand filter, include clean water basin 1, BAF 2 and sand filter 3, BAF 2 and sand filter 3 are built jointly as adjacent organic structures, the channel 4 that BAF 2 pond water outlet is connected with sand filter 3 water-in, also comprise the air purge blower fan 5 that BAF 2 shares with sand filter 3, backwash pump 6, the total air purge airduct of air purge blower fan 5 air-out respectively with BAF 2, sand filter 3 is communicated with, the water suction of backwash pump 6 is from clean water basin 1, the total backwash water pipe of backwash pump 6 water outlet respectively with BAF 2, sand filter 3 is communicated with, the water outlet of sand filter 2 is communicated with clean water basin 1 by pipeline 7.
Air purge blower fan 5 is provided with manual modulation valve 8-1, tensimeter 9-1 successively on the air purge airduct of sand filter 3, and backwash pump 6 is also provided with manual modulation valve 8-2, tensimeter 9-2 on the backwash water pipe of sand filter 3.
Some lattice are divided into respectively in BAF 2 and sand filter 3, and effective Filter length of every lattice is corresponding identical with width with effective Filter length of lattice every in sand filter 3 with width in BAF 2, in BAF 2 and sand filter 3, every lattice form identical filtration area.
BAF and sand filter are built jointly by the utility model, become as a whole structures, BAF and sand filter and only every a pool wall, project can be greatly reduced take up an area, simultaneously that BAF is identical with elevation design at the bottom of the pond of sand filter, easy construction, cost economic.In water level elevation, the filtrate height of sand filter 1.2 meters, its elevation is certain, and the filtrate height of BAF can regulate within the scope of 3 ~ 4 meters, and its elevation is determined by calculating.
The gentle blower fan of washing of backwash water pump of BAF and sand filter is shared.BAF and sand filter are divided into some lattice, and by identical with filter tank with width for the effective Filter length of every lattice of BAF, the backwash water yield, the air purge air quantity of two process structures are just substantially identical, and the gentle air quantity of washing of the backwash water yield all need not regulate.The filtrate height of BAF is greater than sand filter filtrate height, its gentle blast of washing of backwash hydraulic pressure needed is greater than sand filter, the backwash water house steward and air purge house steward in shakeout filter tank arrange tensimeter and manual modulation valve, at limber up period by regulating the aperture of variable valve, by the pressure adjusting of shakeout filter tank backwash water and air purge to the pressure needed.
The utility model water treatment process is that first waste water enter BAF, carries out biochemical treatment in BAF, and the water outlet of BAF enters sand filter, and waste water carries out filtration treatment in sand filter.The water outlet of sand filter enters clean water basin, is finally sent to water spot or arranges mouth outward.
Together with BAF is built jointly with sand filter civil engineering, the water outlet of BAF adopts channel to flow into sand filter.
BAF, in treating processes, filler grows microorganism gradually, and organism is removed, and becomes many gradually in microorganism, needs to carry out backwash when the resistance of filler becomes large, and backwash adopts water backwashing and air purge to combine.Sand filter is in filtration procedure, and filtrate is some blocking gradually, and the head loss of filtrate becomes large, after exceeding certain value, needs to carry out back flushing, adopts water backwashing and air purge to combine.
The water backwashing water pump of BAF, air purge blower fan and sand filter share, consider that every lattice BAF is consistent with the filtration area of every lattice sand filter in design, the backwash water yield in such two ponds is gentle, and to wash air quantity consistent, the gentle pressure washing blower fan of backwash water pump designs by BAF, the backwash water pipe in shakeout filter tank gentle washing on airduct, manual modulation valve and tensimeter are set, when debugging by regulating variable valve and observing tensimeter, backwash water pressure and air purge pressure is made to meet sand filter needs.
