Description

An ABA-type multi-layer water treatment interception box

technical field

The utility model relates to the technical field of sewage treatment, in particular to an ABA-type multi-layer water treatment intercepting box.

Background technique

In recent years, the ecological environment of rivers, lakes, ponds and other water bodies has been heavily polluted by point and non-point sources. The water quality of some rivers is inferior to Class V water quality, which seriously affects the health of the water body. Ecological restoration and green mountains are the purpose of people's governance.

The permeable dam is a kind of interception technology for the purification of water bodies such as river channels. The dam body is often built artificially with materials such as gravel and crushed stone, and the volume of the river channel in front of the dam is used to store one or more surface runoffs. The device combined with the principle of rapid infiltration and the principle of constructed wetlands can purify the sewage to a certain extent. The device with purification effect in the dam body is called the interception box.

A variety of biological fillers can be placed in the interception box, and the biofilm method is used for water treatment. The biofilm method is a method of organic sewage treatment using microorganisms attached to the surface of some solid fillers.

The existing water interception and filtration technology comprehensively utilizes multi-stage and various solid biological fillers, and sets up water inlet and outlet holes to enhance the water purification capacity. The debris of fillers and media may also be discharged with the water flow to form new contaminants.

For biological fillers, such as suspended biological fillers, long-term use will cause the filler wire to agglomerate, break the wire, and break the center rope, and some fillers are not easy to install.

A drawer-type packing area on the water surface, a drawer-type packing device box is inserted into and connected to the drawer-type packing area on the upstream surface and the drawer-type packing area on the backwater surface, and a composite biological spherical filler is arranged in the drawer-type packing device box. A supporting steel pipe is welded on the bottom steel plate of the three-dimensional biological filling area in an orderly manner, the outer surface of the supporting steel pipe is sleeved with a tubular brush type biological filling, and an elastic wire mesh cover is arranged on the top of the three-dimensional biological filling area.

Compared with the prior art, the utility model has the advantages that: the main body of the utility model adopts the structural form of angle steel reinforcement, and the auxiliary box body is woven with gabion mesh, so that the intercepting box body is stable and durable, and the ecological intercepting box body adopts multi-stage In the water treatment mode, the composite biological spherical filler is combined with the three-dimensional elastic filler, which greatly enhances the water treatment effect. The appearance is simple and sophisticated, easy to construct, and the water body runs smoothly. The filler activity can be recovered by flushing. The new tubular brush-type biological filler in the B area can be put on the steel pipe during installation, which is convenient and fast, and has a novel design.

As an improvement, the box body is welded into a rectangular main frame by using angle steel reinforcement.

As an improvement, the drawer-type stuffing device box is woven into a rectangular shape with a gabion net, and the top is open.

As an improvement, the mesh size of the elastic wire mesh cover can allow the support steel pipe to pass through, and play the role of fixing the support steel pipe at the upper part.

As an improvement, the water-facing surface of the box body is a packing device box woven with gabion nets, with small meshes, which play the role of grille interception and facilitate the normal progress of subsequent water treatment.

As an improvement, the particle size of the composite biological spherical filler is larger than the mesh size of the drawer type packing device box, and the composite biological spherical filler is composed of volcanic rock, lime residue, activated carbon and zeolite.
