Specifically, the bearing layer is formed by splicing a plurality of biological floating plates into a whole, and each biological floating plate is provided with a plurality of through holes for placing and fixing the water-cultured plants.

Preferably, the biological floating plate is a flat plastic box with an enclosed air compartment.

Preferably, the outer edge of the biological floating plate is provided with a reserved hole for hooking the filtering unit.

Preferably, the bio-floating plate is detachably fixedly attached to the filter unit by hooking.

Preferably, the plurality of filter units are respectively a cobblestone filter unit with cobblestone filter material, a quartz sand filter unit with quartz sand filter material, a coconut shell activated carbon filter unit with coconut shell activated carbon filter material and a PP cotton filter unit with PP cotton filter material, the water flow direction is perpendicular to the side surface of the filter units, and the water flow direction sequentially flows from the cobblestone filter unit to the quartz sand filter unit, the coconut shell activated carbon filter unit and the PP cotton filter unit.

The utility model discloses can realize under the real black and odorous water condition, carry out the multi-media filtration, improve the power of getting rid of suspended solid, solubility organic matter and ammonia nitrogen. The utility model relates to a black smelly river gushes advanced treatment's novel reliable combination filtration technology not only realizes effectively intercepting dirty and basin's water purification of water point source, can also reduce treatment cost, shortens the engineering time, and simple process maintains ecological stability effectively, has wide market prospect.

Detailed Description

Fig. 1 shows that the utility model discloses a multistage filter equipment for repairing water, it includes: suspend in supporting layer 6 and a plurality of filter unit on water surface, every filter unit includes a cuboid shell that comprises geogrid board, and the shell intussuseption is filled with filtering material, and the outer parcel of filtering material has geotechnological cloth, and a plurality of filter units are according to filter unit from thick to smart order vertical suspension in proper order be fixed in supporting layer 6 bottom and float in the water and form multistage filtration, and the direction that the filter unit stacks around is unanimous with the rivers direction.

The supporting layer 6 is formed by splicing a plurality of biological floating plates 5 into a whole, each biological floating plate is provided with hanging parts protruding outwards at four corners and the middle points of the outer edges, and reserved holes 5.2 are formed in the hanging parts and used for hooking and filtering units. The biological floating plate is also provided with a plurality of through holes 5.1 for placing and fixing the water-cultured plants. As shown in fig. 6, the biological floating plate is a flat plastic box with an enclosed air compartment to provide sufficient buoyancy for the filter unit.
