Abstract

The invention relates to the field of filtering, in particular, to drainage filter systems, and allows to increase the reliability of the system and simplify its design. The drainage system includes waterproof reinforced concrete slabs mounted on the supporting walls. In the gaps between the plates are placed T - shaped porous polymer concrete inserts, the upper part of which is located above the plates. Supporting walls for floor slabs can also be made of polymer concrete. 1 hp f-ly, 3 ill.

Description

The invention relates to filtration and can be used for the purification of natural and after-treatment of wastewater, for example, in industrial fish-farming facilities.

The aim of the invention is to increase the reliability of the filter drain system and simplify its design.

FIG. 1 shows the drainage system of the filter; general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The drainage system includes a collection-distribution channel 1, drainage channels 3 connected to it by means of culverts 2, drainage channels 3, supporting walls 4 and 5 plates installed with a gap between them on supporting walls 4. Porous polymer-concrete inserts 6 are placed in the gaps between the plates 5, having a T-shaped cross section, with this upper part of the inserts placed above the plates 5. The supporting walls 4 can also be made of porous polymer concrete. Filtering load 7 is placed directly on the floor slabs 5. The drainage system works as follows.

Water is filtered from top to bottom through a layer of filter loading 7. The purified water passes through polymer-concrete inserts 6 installed in the gaps between the plates 5 and having a T-shaped cross-section, or through inserts 6 and polymer-concrete supporting walls 4 and enters the drainage channels 3. Next, the purified water through the branch pipes 2 enters the collection and distribution channel 1 and exits the filter. When flushing the filtering load, the wash water is directed from the collecting and distribution channel 1 through the nozzles 2 to the drainage channels 3, passes through the polymer concrete inserts 6 (or the inserts 6 and polymer concrete support walls 4) and enters the loading 7, loosens and flushes it.

The installation of reinforced concrete slabs with a gap between them and the placement of inserts made of porous polymer concrete in the gaps simplifies the drainage design. The T-shape of the insert when placing its upper part above the overlap plates ensures reliable operation of the drainage system, since such an insert under the loading pressure completely covers the gap between the overlap plates and with a certain margin — edges of the plates that may have irregularities, chips and other defects. Thus, the overshoot of loading into the drainage channels and its removal from the filter is completely eliminated.

The plants contaminated with the fine products of fish metabolism increase due to the even distribution of water over the filter area and more efficient washing of the filter charge.
