Abstract
A biological aerated filter cleaning aeration device, comprising a main pipe purge valve, an aerator main pipe, branch pipe gas valves, aerator branch pipes, branch pipe purge valves, aeration holes and a main pipe gas valve. The invention is characterized in that the main pipe purge valve is connected with the aerator main pipe, the aerator main pipe is connected with several branch pipe gas valves, the branch pipe gas valves are separately connected with the aerator branch pipes, the top ends of the aerator branch pipes are connected with the branch pipe purge valve, several aeration holes are arranged on the aerator branch pipes, and the main pipe gas valve is arranged on the aerator main pipe. The invention has the following technical effects: the structure is simple, the operation is convenient and the filter material does not need to be removed from a filter chamber, thus avoiding affecting the normal operation of the filter chamber and reducing the damage of equipments.
Description
Technical field
The present invention relates to a kind of aerating apparatus, relate in particular to a kind of biological aerated filter cleaning aeration device.
Background technology
BAF is the sewage treatment process that contact oxidation technology and suspended substance filtration process are combined, its technological principle is the less particulate filter of a certain amount of particle diameter of filling in the filter tank, the filter material surface microbial film of growing, inside, filter tank is equipped with aerating apparatus, aerating apparatus is distributed in even air in the whole filter tank, with the dissolved oxygen of water in the raising filter tank, thereby satisfy biomembranous needs on the filtrate.Aerating apparatus generally adopts boring aeration pipe or single hole film aeration head aeration.
Aerating apparatus generally is installed in the filter material layer, and the aerating apparatus working process is to utilize gas blower that air is sent into aerating apparatus, and aerating apparatus is distributed in whole filter tank with even air.Because aerating apparatus need be distributed in filter material layer to even air, so its solarization air cap is generally very little, and there is the microbial film of raised growth in the filter material layer, therefore, microbial film might enter in the aeration tube, the solarization air cap on the aeration tube is stopped up or single hole film aeration head is stopped up.The main drawback of this aerating apparatus is: (1) is because be installed in the filter material layer, need after the obstruction all filtrates are cleared and to clean aerating apparatus, and filtrate cleans out the filter tank and it is very big to be installed onto the workload in filter tank, and the time is long, has a strong impact on the filter tank normally to move; (2) even filtrate is cleaned out the filter tank, aerating apparatus also is difficult to clear and coherent, must block aeration tube just and can clean up, and original device is damaged big.
Summary of the invention
The object of the present invention is to provide a kind of biological aerated filter cleaning aeration device, solved initial operating stage, because biomembranous influence on the filtrate, aeration tube and solarization air cap meeting blocking problem, and it is more to have improved in the water suspended substance, when microbial film is thicker, in case BAF stops aeration, under the effect of water pressure, the defective that microbial film and other suspended impurity are easy to enter aeration tube and blocking aeration pipe and solarization air cap.
The present invention is achieved like this, it comprises house steward's cleaning valve, aeration house steward, arm air valve, aeration arm, arm cleaning valve, solarization air cap, house steward's air valve, it is characterized in that house steward's cleaning valve connects the aeration house steward, several arm air valves of the total pipe coupling of aeration, the arm air valve connects the aeration arm respectively, the top of aeration arm is connected with the arm cleaning valve, and the aeration arm has some solarization air caps, and the aeration house steward is equipped with house steward's air valve.
Technique effect of the present invention is: simple in structure, easy to use, do not need filtrate is cleaned out the filter tank, and do not influence the works better in filter tank, reduced damage to device.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a B-B sectional view of the present invention.
In the drawings, 1, house steward's cleaning valve 2, aeration house steward 3, arm air valve 4, aeration arm 5, arm cleaning valve 6, solarization air cap 7, house steward's air valve,
Embodiment
As shown in Figure 1 and Figure 2, the present invention is achieved like this, it comprises house steward's cleaning valve 1, aeration house steward 2, arm air valve 3, aeration arm 4, arm cleaning valve 5, solarization air cap 6, house steward's air valve 7, it is characterized in that house steward's cleaning valve 1 connects aeration house steward 2, aeration house steward 2 connects several arm air valves 3, and arm air valve 3 connects aeration arm 4 respectively, and the top of aeration arm 4 is connected with arm cleaning valve 5, aeration arm 4 has some solarization air caps 6, and aeration house steward 2 is equipped with house steward's air valve 7.During works better, close house steward's cleaning valve and arm cleaning valve, open house steward's air valve and arm air valve, air enters arm by house steward, is evenly distributed to whole filter tank by aeration head on the arm or solarization air cap.When aeration is inhomogeneous, illustrate that aeration arm, aeration head or solarization air cap are stopped up by microbial film or other suspended substance, at this moment need to clean.Cleaning process is: close house steward's air valve and arm air valve, open house steward's cleaning valve, feed high pressure from the beginning current (pressure remains on 0.3～0.5Mpa), open an arm air valve and corresponding arm cleaning valve, current in the house steward enter this aeration arm, this aeration arm is cleaned, and the addle after the cleaning is discharged the filter tank by the arm cleaning valve.After cleaning certain hour, close the arm air valve, at this moment rinse water can not enter this arm, prop up the little spring tube of bore with a diameter than aeration and feed the aeration arm, the aeration arm is stirred, open the arm air valve again from arm cleaning valve one end, at this moment rinse water enters this aeration arm, flushing is clean up to water outlet while stirring, and illustrates to have cleaned up.Change another root aeration arm again and clean, process is identical.
