Description
Technical field
The utility model belongs to sewage filtration equipment, is specifically related to a kind of sewage filter device.
Background technology
The human water that social life caused pollutes and has had a strong impact on ecological environment, it is exactly water pollution problems that China is faced with one of serious day by day problem, a large amount of sewage discharges causes ecological severe exacerbation, has also caused serious harm for mankind itself's quality of life.In the conventional sewage disposal technology, hold back pollutants in sewage through grid, entering sand setting again handles, remove the great material in the sewage, with the precipitation method by after removing the part suspension behind the gravitational settling, enter the sewage disposal stage of next stage, there is the problem of the following aspects in this technology:
1, multi stage precipitation, multistage filtering requires volume of equipment big, causes floor space big;
2, require sewage lifting and plant equipment many, energy-output ratio is big;
3, the operating equipment amount is many, and operation sequence is loaded down with trivial details;
4, cost of sewage disposal height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of precipitation that collects, filtration, blowdown, backwash, backwash is with aeration and at filter packing liquid medicine sterilization one, and floor space is little, plant equipment is few, energy consumption is low, and the simple and good sewage processing effect of operation sequence, cost are low, the sewage filter device that effluent cycle is utilized again.
The technical solution of the utility model: a kind of sewage filter device, comprise container 11, first sewage draining valve 1, sewage inlet valve 2, overflow pipe 3, filter packing 4, backwash aeration tube 5, flange closure plate hand-hole 8 second sewage draining valves 9 and inspection manhole 10, the right side wall of container 11 bottoms is provided with sewage inlet valve 2, left side wall is provided with first sewage draining valve 1, first sewage draining valve 1 is provided with on the flange closure plate hand-hole 8, flange closure plate hand-hole 8 is arranged on the left side wall bottom of container 11, sewage inlet valve 2, flange closure plate hand-hole 8 is communicated with settling zone 6; Container 11 middle parts are provided with two-layer above filter packing 4, are provided with backwash aeration tube 5 between the filter packing 4, and backwash is communicated with container 11 roofs with aeration tube 5; The right side wall on container 11 tops is provided with overflow pipe 3, and left side wall is provided with second sewage draining valve 9, and overflow pipe 3, second sewage draining valve 9 are communicated with filtered water memory space 7, and roof is provided with to be checked with manhole 10.
The utility model compared with prior art has following beneficial effect: the utility model integrates precipitation, filtration, blowdown, backwash, backwash with aeration and at the sterilization of filter packing liquid medicine, and floor space is little, plant equipment is few, energy consumption is low, simple and the good sewage processing effect of operation sequence, cost are low, can effluent cycle be utilized again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of sewage filter device, comprise container 11, first sewage draining valve 1, sewage inlet valve 2, overflow pipe 3, filter packing 4, backwash aeration tube 5, flange closure plate hand-hole 8 second sewage draining valves 9 and inspection manhole 10, the right side wall of container 11 bottoms is provided with sewage inlet valve 2, left side wall is provided with first sewage draining valve 1, first sewage draining valve 1 is provided with on the flange closure plate hand-hole 8, flange closure plate hand-hole 8 is arranged on the left side wall bottom of container 11, and sewage inlet valve 2, flange closure plate hand-hole 8 are communicated with settling zone 6; Container 11 middle parts are provided with two-layer above filter packing 4, are provided with backwash aeration tube 5 between the filter packing 4, and backwash is communicated with container 11 roofs with aeration tube 5; The right side wall on container 11 tops is provided with overflow pipe 3, and left side wall is provided with second sewage draining valve 9, and overflow pipe 3, second sewage draining valve 9 are communicated with filtered water memory space 7, and roof is provided with to be checked with manhole 10.
As shown in Figure 1, during work, pretreated sewage is injected container 11 bottoms by sewage conduct valve 2,, separate the after stain thing by suitably opening outside first sewage draining valve, 1 amount discharge container 11 by gravity natural separation precipitation; Utilize the pressure energy of sewage, the sewage after the separation is successively filtered from the bottom up, utilize filter packing 4 to realize simultaneously the suspension in the sewage is held back, for next step embrane method or biochemical process sewage-treatment plant provides a qualified filtered water.
When needs carry out backwash to filter packing 4, close sewage inlet valve 2, behind standard-sized sheet first sewage draining valve 1,6 form negative pressure in the settling zone, utilize the water after filtering that filter packing 4 is carried out reverse flow, make attached to the pollutant on the filter packing 4 and discharge downwards; When needs carry out comprehensive backwash to filter packing 4, utilize backwash to provide aeration process to filter packing 4 with aeration tube 5, gas washes part filter packing 4 downwards, and forms the zone that is full of air.After backwash is finished, close first sewage draining valve 1, open top second sewage draining valve 9, again after opening sewage valve 2, this regional air upwards carries out the secondary flushing action to filter packing 4 once more, after water to be filtered reaches requirement, close top second sewage draining valve 9, the backwash process of filter packing 4 is finished.In backwash process, if need carry out sterilization at filter packing 4 time, can add bactericide in filtered water with manhole 10 by the inspection on top, realize filter packing 4 is carried out sterilizing by reverse flow.
