Description
Technical Field
The utility model relates to a sewage treatment device field especially relates to a novel inner loop formula bological aerated filter.
Background
The aeration biological filter is a modified form of common biological filter, and can also be seen as a special form of biological contact oxidation method, namely, granular filler with high specific surface area is filled in a biological reactor to provide a carrier for microbial film growth, the granular filler is divided into downward flow or upward flow according to different water flow directions, sewage flows through a filter material layer from top to bottom or from bottom to top, air is blown and aerated at the lower part of the filter material layer, air is in reverse or same direction contact with the sewage, organic matters in the sewage and the biological film on the surface of the filler are stabilized through biochemical reaction, and the filler simultaneously plays a role in physical filtration.
However, when the biological aerated filter in the prior art is operated, no matter the biological aerated filter is in a downward flow or upward flow mode, the flow velocity of inlet water in a water distribution area is greatly reduced, so that a large amount of sludge is collected in the water distribution area, and during the back washing of the biological aerated filter, the collected sludge is floated by back washing water, so that the back washing time is too long. The quality of the effluent is influenced, and the amount of the treated water is greatly reduced, so that the biological aerated filter capable of removing the sludge in the water distribution area is needed.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a novel internal circulation type biological aerated filter which has simple structure and good treatment effect and can effectively remove the sludge in the water distribution area.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that: a novel internal circulation type biological aerated filter comprises a shell, wherein a porous plate is arranged at the middle lower part in the shell, a space is formed between the porous plate and the inner bottom surface of the shell to form a water distribution area, and biological fillers are arranged on the top surface of the porous plate; a layer of filter plate is arranged below the aeration head in the water distribution zone, a distance is reserved between the filter plate and the inner bottom surface of the shell to form a mud collection zone, a mud scraper is arranged at the bottom in the mud collection zone, and a driving shaft of the mud scraper downwards penetrates through the bottom wall of the shell to be connected with a rotating motor; a sludge outlet is formed in the bottom surface of the sludge collection area, a sewage inlet is formed in one side of the lower portion of the sludge collection area, and a purified water outlet is formed in one side of the top of the shell.
Furthermore, a backwashing water inlet pipe is installed on one side wall of the shell above the biological filler, and a backwashing water outlet pipe is installed on one side wall of the sludge collection area.
Further, the lower part of the shell is provided with a fixed supporting leg.
Further, the aeration head is a microporous aeration head.
The utility model has the advantages that: through set up the filter screen in the water distribution district, with mud isolated under the filter screen, the mud of long-pending silt is struck off through the mud scraping plate, has effectively got rid of water distribution district mud collection, the back flush of being convenient for, and the treatment effect is good, has avoided mud collection to the influence of play water quality of water and play water speed.
