Firstly, sewage enters the concentration tank 1 through an original water inlet pipe in the existing concentration tank 1, and the original water inlet pipe is not affected in an upward or downward way. After sewage enters the concentration tank 1, the sewage is subjected to precipitation treatment in the concentration tank 1, and after a certain time of precipitation, the sediment gradually falls to the lower part of the concentration tank 1 and finally falls onto the assembled self-flushing ash precipitation device arranged in the concentration tank 1, namely each U-shaped groove 4, and two different cover plates are adopted on the upper end face of the assembled self-flushing ash precipitation device according to different ash flushing system modes.
Example 1

After the sediment falls down, the sediment firstly falls on the inclined cover plates 11, as the inclined cover plates 11 are obliquely arranged, gaps are reserved between every two adjacent inclined cover plates 11, the sediment finally falls on the bottom plate inside the U-shaped groove 4 from the gaps between the inclined cover plates 11, the sediment is accumulated for a period of time, then the main pipeline 7 is opened intermittently and alternately, after one main pipeline 7 is supplied with water, the sediment is conducted to a tee joint 10 in a selected mode, finally the front-most main pipeline 7 is shut off, high-pressure water is poured into the branch pipes 8 at the same time, finally the spray heads 9 at the tail ends of the branch pipes 8 are sprayed out, the spray heads 9 adopt spherical crown type ash flushing spray heads 9-1 or cylindrical ash flushing spray heads 9-2, the spray direction is changed from wide to narrow along the radial section, and towards the central mud collecting area 3, at the moment, under the action of high-pressure water spraying of the spray heads 9, the sediment on the bottom plate inside the U-shaped groove 4 is flushed towards the central mud collecting area 3, and after the sediment is subjected to the action of high-pressure water, the sediment is boiled upwards, and most of the sediment is sprayed out from the inclined cover plates 11 in the middle of the inclined groove 4, and then the sediment is discharged towards the central mud collecting area along with the high-pressure water, and the sediment is discharged along with the high-pressure water flowing upwards in the spray area. After one side is washed, the other side is started to wash again, so that the washing is started alternately after a period of time, and the effect of rapid washing is achieved. The intermittent alternate opening of the main pipeline 7 is that the more the sediment is near the center area, the more the sediment is near the wall of the sedimentation tank, namely the periphery, and the less the sediment is, so that the intermittent alternate opening is adopted to save flushing water on one hand and to wait for the sediment to be accumulated and then to be flushed on the other hand, and the same saving effect is achieved.

As shown in fig. 5 and 6, when the reversible sealing turnover plate 13 is disposed on the assembled self-ash-washing precipitation device, the ash-washing system is disposed in the assembled self-ash-washing precipitation device in this state. When the sediment falls down, the sediment firstly passes through the gap between the sealing turnover plates 13 and finally falls onto the bottom plate inside the assembled self-ash-flushing sedimentation device unit, the sediment is accumulated for a period of time, then the sediment passes through intermittent alternate combined ash flushing pipes 12, one of the combined ash flushing pipes 12 is supplied with water, then one side of the combined ash flushing pipes is conducted through the tee joint 10, and finally the sediment is intercepted by the foremost combined ash flushing pipe 12. The integrated spray pipe adopted by the combined ash flushing pipe system belongs to section type spray, and the spray hole 12-3 at the tail end of each section sprays forwards while the clean water flows through each section of spray pipe. The forward water pressure generated in the spraying turns the sealing turning plates 13, so that the sealing turning plates 13 turn clockwise, at the moment, the upper ports of the assembled self-flushing ash precipitation devices at the moment are in a sealing state when the front and back lamination of every two adjacent sealing turning plates 13 is carried out, and the spraying water drives sediment at the bottom of the pond to move towards the central mud collecting area 3, so that the sediment is rapidly discharged; meanwhile, the sediment above does not fall into the assembled self-flushing ash precipitation device at the moment, only falls on the sealing turnover plate 13, and the sediment in the assembled self-flushing ash precipitation device at the moment is reduced, so that the sediment in each U-shaped groove can be impacted by high-pressure water with greater power, and flushing is performed rapidly.
According to the utility model, through a mode of combining the assembled self-ash-flushing precipitation device and the ash-flushing system, the precipitate is collected through the assembled self-ash-flushing precipitation device, and then the automatic flushing is performed through the ash-flushing system, so that the manual ash flushing operation is avoided, the labor amount is reduced, and meanwhile, the timely ash flushing in the concentration tank 1 can be ensured, and the trouble and the labor are saved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the technical solutions according to the embodiments of the present utility model.
