It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art.
The following examples are further illustrative in combination to facilitate understanding of the embodiments, and are not to be construed as limiting the invention.
Example 1: as shown in fig. 1 and 2, the anti-clogging device for the water treatment inclined plate filler comprises a sedimentation tank 1, a bottom inclined plate 2, a water distribution weir 3, an air compressor 4, a pneumatic valve 5, a perforated pipe 6 and a sludge discharge pump 7; the bottom swash plate 2 is arranged and installed in the cavity of the sedimentation tank 1, a water distribution weir 3 is arranged on one side of the outside of the sedimentation tank 1, the air compressor 4 is connected with one end of the pneumatic valve 5, the other end of the pneumatic valve 5 is connected with the perforated pipe 6, the sludge discharge pipeline of the sludge discharge pump 7 is installed at the bottom of the sedimentation tank 1, the sludge discharge pipeline of the sludge discharge pump 7 is arranged below the perforated pipe 6, and the bottom swash plate 2 is arranged in the cavity of the sedimentation tank 1.
The bottom of a filler of a traditional sedimentation tank 1 is provided with a plurality of perforated pipes 6, the distance between each perforated pipe 6 and a bottom inclined plate 2 is 20-30cm, the distance between each perforated pipe 6 is 10-30cm, the opening distance between each first hole 8 and each second hole 9 of each perforated pipe 6 is 10-20cm, the opening directions of the first holes 8 and the second holes 9 are outwards opened at 45-degree angles in a staggered mode, and the opening sizes of the first holes 8 and the second holes 9 are 5-10 mm.
The plurality of perforated pipes 6 are respectively connected with the air compressor 4 through pneumatic valves 5, and the pneumatic valves 5 control the aeration of the perforated pipes 6. The perforated pipes 6 are aeration pipes perforated at the bottom of the filler, and the number of the aeration pipes is less than 200.
The utility model discloses need to set up water distribution weir 3 in the intake position of sedimentation tank 1 that has bottom swash plate 2, the reaction tank goes out water and need get into sedimentation tank 1 through upper portion water distribution weir 3, and this gist is for preventing that sedimentation tank 1 from reducing the liquid level in-process, and reaction tank play water gets into sedimentation tank 1, leads to sedimentation tank 1 can't reduce the liquid level in the short time.
Example 2: as shown in fig. 1 and 2, the anti-clogging device for the water treatment inclined plate filler comprises a sedimentation tank 1, a bottom inclined plate 2, a water distribution weir 3, an air compressor 4, a pneumatic valve 5, a perforated pipe 6 and a sludge pump 7, and comprises the following steps;
when the device is operated, water inlet of the sedimentation tank 1 is stopped, if the sludge pump 7 exists, the sludge pump 7 needs to be stopped, after water outlet of the sedimentation tank 1 is stopped, the sludge pump 7 is started, and the liquid level of the sedimentation tank 1 is reduced by 10-20cm through sludge discharge of the sludge pump 7.
For preventing when the aeration of sedimentation tank perforated pipe, the liquid level rises in the sedimentation tank 1, leads to the pollutant to flow out of sedimentation tank 1 along with the play water, reduces the liquid level in the sedimentation tank 1 before the aeration, can effectively avoid this phenomenon to take place. The liquid level lowering of the sedimentation tank 1 is realized through the sludge discharge pump 7, and an independent liquid level lowering pump is not added.
After the liquid level of the sedimentation tank 1 is reduced, the pneumatic valve 5 is started, the inclined plate 2 is flushed through aeration of the perforated pipe 6, the flushing time is generally controlled to be 1-5 minutes, and after the flushing is finished, the pneumatic valve 5 is closed.
And starting water inlet after 5-10 minutes, and carrying out normal operation. The key point is that a large amount of suspended matters in the sedimentation tank 1 after the perforated pipe is aerated are precipitated, and pollutants are prevented from being discharged along with discharged water after water enters.
The operation is carried out once at intervals of 15-30 minutes according to the steps, so that the phenomena of rising of effluent suspended matters of the sedimentation tank, uneven effluent of the sedimentation tank, collapse of the inclined plate and the like caused by blockage of the inclined plate in the traditional inclined plate and inclined tube sedimentation tank can be effectively avoided.
As described above, although the embodiments of the present invention have been described in detail, it will be apparent to those skilled in the art that many modifications are possible without substantially departing from the invention and its effects. Therefore, all such modifications are included in the scope of the present invention.
