Description
Technical field
The utility model is related to sewage-treatment plant, more particularly to a kind of pressure type filter.
Background technology
Common pressure type filter is using lower to stream filter type.Due to the natural waterpower sieving actoion of backwash, greatly
Granule filter material is located at bottom, and little particle filtrate is located at top, formd from top to bottom, the arrangement mode that filtrate gradually increases.This
Planting filtrate arrangement mode makes the pollutant of filtrate top retention more, easily forms both surface filtration.With the increase of filtration time,
Filtration resistance rises, and filtering layer is easily pierced, and filter effect declines, and filtering water outlet deteriorates.
In order to improve filter effect, use double-layer filter material, top is bulky grain filtrate, and bottom is little particle filtrate more, this
Both surface filtration can effectively be prevented by planting filtrate filling mode；But layer is easily mixed in backwash, filter effect is influenceed.
Further, since water (flow) direction is from top to bottom, filtrate is easily progressively compacted, and such as backwash cycle is longer, easily causes
Filtrate is hardened, influence backwash and filter effect；If improving backwash frequency, the increase of backwash water is caused.Especially contain poly- third
It is hardened that filtrate is more easily caused during the sewage water filtrations of organic matter such as acrylamide (PAM).
Accordingly, it would be desirable to which one kind can easily form both surface filtration, filtrate efficiently against existing filter mixes layer and filtrate plate
The Novel filter device of the shortcomings of knot.
