Abstract
The utility model relates to a high-efficiency flushing apparatus for filters adopting expansion filling, which comprises a filer body, a biological activated carbon filter material layer, a water distributor, an air distributor and a purified water-receiving trough, the water distributor, the air distributor and the biological activated carbon filter material layer are sequentially arranged from the bottom up in the filter body, and a water distribution inlet of the water distributor and a working aeration inlet of the air distributor are extended out of the filter body; a flushing water-receiving trough and the purified water-receiving trough are arranged on the outer side of the upper opening of the filter body; and the water distribution inlet is connected with a flushing water inlet and a flushing water pump. The utility model has the advantages that: because the water level in the filter is decreased due to water level-decreased flushing, the pressure needed by the flushing water pump and a flushing fan is decreased, and energy is saved; since the water level in the filter is decreased due to water level-decreased flushing, an expansion area is provided for activated carbon, consequently, the activated carbon can welter and rub under the normal water level in the process of flushing, so that biomembranes can be separated, the separated biomembranes flow out of the system along with the flushing water, and thereby the flushing effect is enhanced.
Description
Technical field
The utility model relates to a kind of high efficiency flushing device that all adopt the filter tank (as BAF, activated carbon filter and charcoal absorption pond etc.) of swelling property filler that is used for, be applicable to polluted river water, the improvement of lake, little pollution river, also can be used for high-quality regeneration waterworks construction.
Background technology
The pollution substance (dissolving, suspension, colloidalmaterial and microorganism etc.) that in polluted river water, little pollution river lake water, exists various forms to exist, when adopting biological activated carbon treating pond or BAF, activated carbon filter and charcoal absorption pond to handle, after operation for some time, biofilm biomass increases gradually on the filtrate, resistance to water increases, filtering velocity descends, and just need wash the filter tank when resistance acquires a certain degree.Present purging method is directly the filter tank to be washed when full-water level, and the aeration of the water of flushing adds from the bottom, filter tank, and the water after the flushing is discharged from the water receiving tank of purifying waste water at top, filter tank.The shortcoming that above-mentioned purging method exists is: full-water level has increased the watt consumption of wash-water pump and flushing blower fan, causes the waste of the energy; Owing to be full-water level, make that the water quantity discharged (ratio) after the flushing descends, reduced developing result; Can not be for gac provide expansion area, limited rolling, rubbing of gac in the flushing process, reduced biomembranous disengaging, also can reduce developing result.
Summary of the invention
The purpose of this utility model provides a kind of high efficiency flushing device that all adopt the filter tank of swelling property filler that is used for, to solve the high and low problem of developing result of power consumption that prior art exists.
The technical solution of the utility model is: comprise pond body, filter material layer, water-distributing device, the distribution device in filter tank and the water receiving tank of purifying waste water, be disposed with water-distributing device, distribution device and filter material layer in the body of pond from bottom to up, it is external that the cloth water inlet of this water-distributing device and the work aeration of distribution device inlet all pass this pond; The outside in the upper port of this pond body is provided with the wash-down water water receiving tank, is provided with the water receiving tank of purifying waste water in the outside of this wash-down water water receiving tank, and the top, outer of this wash-down water water receiving tank is higher than the top of pond body and is lower than the top of the water receiving tank outer of purifying waste water; Be respectively equipped with wash-down water outlet and treated water outlet in the bottom of this wash-down water water receiving tank and the water receiving tank of purifying waste water; Be connected to flushing water-in and wash-water pump at described cloth water inlet, be connected to the flushing inlet mouth at described work aeration inlet.
Between described water-distributing device and distribution device, be provided with the filter back up pad.
The beneficial effects of the utility model are:
1, the flushing of precipitation position has reduced wash-water pump and the required pressure of flushing blower fan because the filter tank median water level reduces, and has saved the energy;
2, the flushing of precipitation position at first reduces the filter tank median water level; for gac provides expansion area; make that gac rolls, rubs with the lower section at ordinary water-level in the flushing process; microbial film is broken away from; the microbial film that comes off is with the wash-down water outflow system; this process has reduced the friction probability of gac and upper strata catch net, reduces the wearing and tearing and the loss of gac.
