Abstract
The invention discloses a multi-media filter. The multi-media filter comprises a shell (1) and supporting legs (2), wherein a water inlet (3) is formed in the top of the shell (1); a filter plate (4) is arranged on the lower part of the shell (1); a filter layer (5) is arranged on the upper side of the filter plate (4), and comprises an anthracite layer (6), a quartz sand layer (7) and a pebble layer (8) from top to bottom; the particle size of particles in the anthracite layer (6) and the pebble layer (8) is greater than that of particles in the quartz sand layer (7); and a water outlet (9) is formed in the bottom of the shell (1). The filter layer of the multi-media filter removes suspended impurities step by step according to the size of the particles, so that the capacity of suspended matters in the discharged water after filtration can be below 5mg/L; and with the quartz sand layer, the discharged water infiltrates smoothly under the action of gravity, and pollutants in water are retained step by step through quartz sands with different particle sizes. The whole multi-media filter has the characteristics of simple structure, convenience in operation and high quality of the discharged water, and is suitable for popularization and application.
Description
Technical field
The present invention relates to water-treatment technology field, specifically a kind of simple in structure, easy to operate, more medium filter that effluent quality is good.
Background technology
More medium filter is to utilize one or more filter mediums, pass through certain thickness granular or non-grain material at the higher water of the following turbidity of certain pressure, thereby effectively remove the process that suspended impurity makes clarification of water, filtrate commonly used has quartz sand, anthracite, manganese sand etc., be mainly used in the water treatment turbidity removal, demineralized water, the prime preliminary treatment of pure water etc., though existing more medium filter filter course adopts multiple filter medium, owing to do not fully take into account the relation of the order of filtration in the sewage disposal, cause that filter effect is bad, effluent quality is poor.
Summary of the invention
The objective of the invention is the problem that exists at prior art, a kind of simple in structure, easy to operate, more medium filter that effluent quality is good is provided.
The objective of the invention is to solve by the following technical programs:
A kind of more medium filter, the leg that comprises housing and support housing, the top of described housing is provided with water inlet, lower part of frame is provided with filter plate, the upside of filter plate is provided with filter course, filter course comprises anthracite coal measure, quartz sand layer and boulder bed from top to bottom, and particle grain size is greater than particle grain size in the quartz sand layer in anthracite coal measure and the boulder bed, and the bottom of housing is provided with delivery port.
Described quartz sand layer comprises last quartz sand layer and the following quartz sand layer on top, and particle grain size is greater than particle grain size in the following quartz sand layer in the last quartz sand layer.
Described filter plate is provided with equally distributed drain cap.
Described filter plate adopts support member to be fixed in the housing.
Described housing is provided with the visor in order to observe.
One side of described water inlet is provided with the exhaust outlet that is communicated with the housing inner chamber.
All be provided with manhole on the housing of described filter course upside and filter plate downside.
The present invention has following advantage compared to existing technology:
Former water was from top to bottom when the filter course when the present invention used, suspension in the water since absorption and mechanical choked flow effect be retained down by the anthracite coal measure at top; When current are middle through filtering layer, because it is tightr that the sand grains in the quartz sand layer is arranged, make in the water particulate that more opportunity and sand grains collision are arranged, so flocculation material, suspension and sand grain surface adhere to mutually in the water, impurity is trapped in the quartz sand layer in the water, thereby the water quality that obtains clarifying, the aqueous suspension that goes out after filtering can be below 5 mg/litre; Utilize the density difference of different medium in the filter course simultaneously, the disorder of filter material layer when having avoided the bottom-up cleaning filtrate of in backwash process current.
Water outlet after quartz sand layer layering of the present invention is arranged to filter the gravity effect following ooze smooth and easy, quartz sand through different-grain diameter is progressively held back water pollutant, characteristics simple in structure, easy to operate, that effluent quality is good that equipment integral body has, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-housing; 2-leg; 3-water inlet; 4-filter plate; 5-filter course; 6-anthracite coal measure; 7-quartz sand layer; 8-boulder bed; 9-delivery port; 10-upward quartz sand layers; 11-following quartz sand layer; 12-drain cap; 13-support member; 14-visor; 15-exhaust outlet; 16-manhole.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1: a kind of more medium filter, the leg 2 that comprises housing 1 and support housing 1, be provided with water inlet 3 at the top of housing 1, one side of water inlet 3 is provided with the exhaust outlet 15 that is communicated with housing 1 inner chamber, the bottom of housing 1 is provided with adopts support member 13 to be fixed on filter plate 4 in the housing 1, filter plate 4 is provided with equally distributed drain cap 12, the upside of filter plate 4 is provided with filter course 5, filter course 5 comprises anthracite coal measure 6 from top to bottom, quartz sand layer 7 and boulder bed 8,8 particle grain size are greater than particle grain size in the quartz sand layer 7 in anthracite coal measure 6 and the boulder bed, quartz sand layer 7 comprises last quartz sand layer 10 and the following quartz sand layer 11 on top, particle grain size is greater than particle grain size in the following quartz sand layer 11 in the last quartz sand layer 10, and the bottom of housing 1 is provided with delivery port 9.On being provided with housing 1 in order to the visor 14 observed and filter course 5 upsides and filter plate 4 downsides, housing 1 all is provided with manhole 16 in addition.
When the present invention uses, by depth-type filtration particle bigger in the water is removed at the top layer of filter course 5, smaller particles is removed than the depths filter course 5, thereby makes the standard after water quality reaches coarse filtration.Specifically former water is from top to bottom when the filter course 5, suspension in the water since absorption and mechanical choked flow effect be retained down by the anthracite coal measure 6 at top; In the time of in the middle of current pass through filtering layer 5, because it is tightr that the sand grains in the quartz sand layer 7 is arranged, make in the water particulate that more opportunity and sand grains collision are arranged, so flocculation material, suspension and sand grain surface adhere to mutually in the water, impurity is trapped in the quartz sand layer in the water, thereby the water quality that obtains clarifying, the aqueous suspension that goes out after filtering can be below 5 mg/litre; Utilize the density difference of different mediums in the filter course 5 simultaneously, the disorder of filter material layer 5 when having avoided the bottom-up cleaning filtrate of in backwash process current.Water outlet after quartz sand layer 7 layerings are arranged to filter in addition the gravity effect following ooze smooth and easy, the characteristics that overall structure has is simple in structure, easy to operate, effluent quality is good, suitable promoting the use of.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of doing on the technical scheme basis all falls within the protection domain of the present invention; The technology that the present invention does not relate to all can be realized by prior art.
