This example provides 3 backflushing tanks.

As shown in figure 3, because the mouth of the siphon break tank 17 is higher than the lowest end of the water outlet 5, the liquid level is initially at A, and the liquid level drops to B when back flushing is carried out, the liquid level only drops to C during the period that the siphon break pipe 18 sucks water in the siphon break tank 17 and exposes out of the siphon break pipe 18, thereby ensuring that clean water is always produced.

Example 2

On the basis of the embodiment 1, the lower part of the settling zone 2 is provided with a plurality of sludge cone hoppers 6, the sludge cone hoppers 6 are hollow pyramids, the middle part of the settling zone is provided with an inclined pipe 8, the upper part of the settling zone is provided with a supernatant water collecting tank 19, and one end of the supernatant water collecting tank 19 in the middle of the three-way pipe 20 is communicated with a descending pipe 13. The sludge cone hopper 6 can concentrate the sludge precipitated at the bottom of the precipitation zone 2 at one position, so that the sludge is convenient to concentrate; the supernatant water collection tank 19 can collect the clarified water for further processing.

Furthermore, a sludge discharge pipe 7 is arranged between the sludge cone hoppers 6. The sludge discharge pipe 7 can discharge the sludge concentrated between the sludge cone hoppers 6 out of the sedimentation tank.

Example 3

On the basis of the embodiment 2, the filter layer 11 is composed of at least three layers of filter fillers 9, and the particle sizes of the filter fillers 9 are gradually increased from top to bottom. In order to improve the filtering effect, three layers of filtering fillers are arranged, a drilling steel plate 21 is further arranged at the lowest layer of the filtering fillers 9, and a water cap 22 is arranged at the drilling position of the drilling steel plate 21.

As described above, the present invention can be preferably realized.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and the technical essence of the present invention is that within the spirit and principle of the present invention, any simple modification, equivalent replacement, and improvement made to the above embodiments are all within the protection scope of the technical solution of the present invention.
