A sump is proposed that includes a housing, on the outside of which there are pipes respectively supplying dirty water together with a reagent, discharging purified water and sediment, and inside there are soothing elements, and a distinctive feature is that inside the housing after pipes for supplying dirty water and discharged purified water Soothing elements were installed in the form of water in the form of packets of diverging and converging plates, respectively, with a grid between them with a live section from 20 to 95%. The angle of divergence between adjacent plates in the package of diverging plates is from 3 to 15 °, and the angle of convergence between adjacent plates in the package of converging plates is from 5 to 20 ° and the number of plates in the packages of converging and diverging plates is from 3 to 10, and plate packs converging and diverging plates can be made of magnetic material. In this case, the grid is located from the package of converging plates at a distance of 10 to 45% of the total distance from the package of diverging to the package of converging plates.

The efficiency of wastewater treatment using the proposed sump is increased by 15-20% compared with treatment in the known sump.

The proposed utility model can be used in various industries in wastewater treatment processes.

Description

Technical field

The proposed utility model relates to apparatus and devices for wastewater treatment.

State of the art

Known sump, comprising a housing, on the outer side of which there are pipes respectively supplying dirty water, discharging purified water and sediment, and inside soothing partitions in the form of complex elements, for example, a spherical bump, rotary mounted on a horizontal axis under the outlet end of the central pipe, vertically mounted in the case (RF patent for the invention №: 2045987, etc. 20.10.1995).

A significant disadvantage of the known sump is the low efficiency of water treatment in the sump due to its turbulization inside the sump, starting from the entry of dirty water into the sump to the discharge of purified water from the sump.

The closest technical solution to the proposed utility model is a sump, including a casing, on the outside of which there are pipes for supplying dirty water, discharging purified water and sediment, and soothing elements inside (RF patent No. 2006247, etc. 07.06.1991 - prototype).

A significant disadvantage of the known sump is the low efficiency of water treatment in the sump due to its turbulization inside the sump, starting from the entry of dirty water into the sump to the discharge of purified water from the sump.

Disclosure

The challenge is to develop a new design that provides a high degree of pollution removal.

The technical result is to increase the efficiency of wastewater treatment.

The task and the specified technical result are achieved by the fact that a sedimentation tank is proposed, including a housing, on the outside of which there are nozzles for supplying dirty water together with a reagent, for discharging purified water and sediment, and inside there are soothing elements and the distinctive feature is that that inside the case after the pipes for supplying dirty water and drainage of purified water soothing elements are installed in the form of packets of diverging and converging plates, respectively, from the location m between them mesh with the living section from 20 to 95%. The angle of divergence between adjacent plates in the package of diverging plates is from 3 to 15 °, and the angle of convergence between adjacent plates in the package of converging plates is from 5 to 20 ° and the number of plates in the packages of converging and diverging plates is from 3 to 10, and plate packs converging and diverging plates can be made of magnetic material. In this case, the grid is located from the package of converging plates at a distance of 10 to 45% of the total distance from the package of diverging to the package of converging plates.

Utility Model Implementation

The proposed sedimentation tank includes (Fig. 1) a housing 1 with a conical bottom 6, on the outside of which there are pipes respectively for supplying dirty water together with reagent 2, for discharging purified water 4 and sediment 5 and a cover 3, and soothing elements in the form of packets are installed inside, respectively diverging 7 and converging plates 8 with the location between them of the grid 9 with a live section from 20 to 95%.

In this case, the angle of difference between adjacent plates in the package of diverging plates is from 3 to 15 °, and the angle of convergence between adjacent plates in the package of converging plates is from 5 to 20 ° and the number of plates in the packages of converging and diverging plates is from 3 to 10, and plate packs converging and diverging plates can be made of magnetic material. In this case, the grid is located from the package of converging plates at a distance of 10 to 45% of the total distance from the package of diverging to the package of converging plates.

The principle of operation of the proposed sump is as follows. Dirty (source) water together with the reagent enters the housing 1 through the pipe 2 and then through a packet of diverging plates 7, and then through the grid 9 and a package of converging plates 8 through the pipe of the outlet of purified water is discharged from the sump. The contaminants that separate into the cleaning process precipitate, which is discharged through pipe 5.

In this case, the angle of divergence between adjacent plates in the package of diverging plates is from 3 to 15 °.

At the same time, the intensification of the water treatment process is facilitated by the fact that the angle of convergence between adjacent plates in the package of converging plates is from 5 to 20 °, and the number of plates in the packages of converging and diverging plates is from 3 to 10, and the plates of the packages of converging and diverging plates can be made of magnetic material. In this case, the grid is located from the package of converging plates at a distance of 10 to 45% of the total distance from the package of diverging to the package of converging plates.

The efficiency of wastewater treatment using the proposed sump is increased by 15-20% compared with treatment in the known sump.

The proposed utility model can be used in various industries in wastewater treatment processes.
