As shown in fig. 1, the box 1 is horizontally disposed, wherein the splicers are located on four side walls of the box 1, and the multiple boxes 1 can be spliced into a plane by the splicers to form a processing layer. Wherein, the communicating pieces are positioned on the upper surface and the lower surface of the box body 1, so that water can pass through the treatment material in the box body 1, and the water treatment is realized.

The effect of the technical scheme of this embodiment is, deposit the processing material in the box 1 through setting up, can realize that multiple processing mode combines, can select the reaction box of filling with corresponding processing material by oneself according to the condition that needs used. The splice through setting up can constitute one side and handle the layer, can constitute one and handle water, when certain reaction tank is unable to use, can only change this reaction tank alone, need not all to demolish whole processing layer, has practiced thrift treatment cost and processing time.

Preferably, in this embodiment, the splicing pieces are pin rods 2 and slots 3, and the two mutually spliced sides of the box body 1 are respectively provided with a plurality of pin rods 2 and a plurality of corresponding slots 3.

The pin rods 2 and the slots 3 can be conveniently spliced with each other for the adjacent box bodies 1, and the pin rods 2 can be inserted into the corresponding slots 3. Wherein the case 1 is provided with two pins 2 or two slots 3 at one side thereof so that the manufacture is easier.

Preferably, in this embodiment, the communicating member is a first through mesh 4, two opposite surfaces of the box 1 are both provided with first through holes communicated with the inner cavity, and the first through mesh 4 is fixedly connected to the first through holes.

Wherein, the treatment material in the box 1 can not leak out of the box 1 through the first transmission grid 4, and the water can pass through the box 1 through the first transmission grid 4, and the treatment material can treat the water.
