Preferably, the inner diameter of the main pipe is gradually reduced from the water inlet to the closed end. The pressure of each jet branch pipe is the same, the flow velocity of water flow ejected by the jet branch pipes is the same, and rotational flow is generated more easily.

Preferably, the filler is any one of resin, activated carbon particles, building sand, quartz sand, zeolite, ceramsite, soapstone and brick scraps.

Preferably, the filtering assembly comprises two inclined plate groups which are arranged up and down, and the inclined angles of the two inclined plate groups are opposite. The inclined plate is used for intercepting small-particle-size and friction-broken filler, prevents the filler from flowing out from the reflux port and the water outlet along with water flow, improves the concentration of crystal seeds in the tower, and maintains the iron removal efficiency of crystallization.

Preferably, a plurality of guide plates are arranged in the catalytic packing area, and the guide plates are positioned between the filter assembly and the main pipe. The guide plate divides the inner cavity of the tower body into a plurality of compartments so as to weaken rotational flow and change the rotational flow into ascending laminar flow.

Preferably, the filler has a particle size of 0.1 to 3.0mm. The particle size is too large, the specific surface area is small, and the rapid crystallization is not facilitated; the particle size is too small and is easy to be carried away by water flow to be lost, and the fluidization state is unstable.

The utility model has the advantages that:

1. the utility model discloses in through adding female pipe and efflux branch pipe, form high-speed whirl, make to pack and maintain the fluidization state.

2. The utility model discloses well female pipe internal diameter reduces gradually and makes everywhere efflux branch pipe pressure the same, and the velocity of flow that the efflux branch pipe jetted out equals, produces the whirl more easily.
