Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

A kind of rapid filter as shown in Fig. 1-Fig. 3, comprises pond body 1, and the bottom of pond body 1 is provided with filter material layer 2 and support layer 3 from top to bottom, and the exterior of pond body 1 is provided with muddy water channel 4, The waste water channel 5 and the pipe gallery parts, the pool body are equipped with a water distribution system and a flushing drainage tank 92, and the water distribution system is arranged at the lower part of the support layer 3, and the filter material layer 2 is a double-layer or three-layer structure. the

Embodiment one:

As shown in FIG. 2 , the filter material layer 2 has a double-layer structure, including an anthracite layer 21 and a quartz sand layer 22 arranged from top to bottom.

Embodiment two:

As shown in FIG. 3 , the filter layer 2 has a three-layer structure, including an anthracite layer 21 , a quartz sand layer 22 and a garnet layer 23 arranged from top to bottom.

Further, the pipe gallery components include a water inlet main pipe 6, a flushing water main pipe 7 and a clean water main pipe 8 arranged from top to bottom. 71 is connected with the clean water branch pipe 81, the water inlet branch pipe 61, the flushing water branch pipe 71 and the clean water branch pipe 81 are respectively provided with the first, second and third valves 62, 72, 82, the water inlet branch pipe 61 is connected with the muddy water channel 4, and the muddy water The water channel 4 is communicated with the pool body 1, the flushing water branch pipe 71 is communicated with the pool body 1, the clear water branch pipe 81 is communicated with the flushing water branch pipe 71, the muddy water channel 4 is arranged on the top of the waste water channel 5 and the bottom of the muddy water channel 4 is provided with a water discharge into the waste water The drain valve 41 of the channel 5. the
