Abstract
The invention discloses a high-efficiency washing method and a high-efficiency washing device for a filter adopting expansive fillers. The structure and working process comprise that: a valve for water inlet, a valve for normal water outlet and a valve for aeration are closed; a water level in the filter is reduced to a washing water level through drainage, wherein the washing water level is lower than a normally working water level; a valve for washing water inlet and a valve for washing aeration at the lower part of the filter are opened and a purification device in the filter is washed by using upward water flow and airflow; and the washing water is discharged from a washing water outlet at the bottom end of a washing water receiving tank outside the top end of the filter. The invention has the advantages that: due to reduction of the water level in the filter, the reduced water level washing reduces pressure needed by a washing water pump and a washing fan and the energy are saved; the reduced water level washing is to reduce the water level in the filter first to provide an expansion area for activated carbon, so that the activated carbon rolls to form friction on the part below the normal water level in the process of washing. Therefore, the biofilm is separated and flows out of the system along with the washing water, and the washing effect is improved.
Description
Technical field
The present invention relates to a kind of efficient purging method that all adopt the filter tank (as BAF, activated carbon filter and charcoal absorption pond etc.) of swelling property filler that is used for, and the isolated plant of implementing this method, 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 invention is to provide a kind of efficient purging method and device that all adopt the filter tank of swelling property filler that be used for, to solve the high and low problem of developing result of power consumption that prior art exists.
Technical scheme of the present invention is:
A kind of efficient purging method that is used for the filter tank of all employing swelling property fillers is characterized in that its flow process comprises: close the into valve of water, normal water outlet, aeration; Draining is reduced to the flushing water level with the filter tank median water level, and this flushing water level is lower than the water level of works better; Open the flushing water inlet of bottom, filter tank and the valve of flushing aeration, utilize current upwards and air-flow that the refining plant of inside, filter tank is washed; Wash-down water is discharged from the wash-down water outlet of the wash-down water water receiving tank bottom in the outside, top, filter tank.
A kind ofly implement the described device that is used for the efficient purging method in all filter tanks of adopting the swelling property fillers, it is characterized in that, 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.
The invention has the beneficial effects as follows:
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.
