Description

The utility model relates to means for forming the walls of integrated systems for the removal and treatment of surface runoff of rain, melt and irrigation water from roads, railways, and can be used in particular to form a bioplate wall in a wastewater treatment system.

Known filter materials from gabions coated on the inside with geotextiles, of which the vertical walls of the filter chambers of the drainage and surface drainage treatment system are made (Pat. RU 2200802, E03F 1/00, C02F 1/00, 03/20/2003).

The disadvantages of these filter materials are their clogging and clogging with mechanical impurities, and the lack of regeneration, which reduces the quality of cleaning.

Mesh box-shaped containers filled with stones are known, the outer edges of which are formed by stone material from igneous and / or metamorphic rocks, and the inner space is filled with limestone (Pat. RU 49526, C02F 3/32, July 28, 2005). Box containers are used to form the walls of the settling chamber and the bioplate.

The disadvantages of these box-shaped containers is that they become clogged, clogged by mechanical particles and the inability to regenerate them, which reduces the quality of cleaning.

Known box-shaped gabion structures for forming the walls of the chamber of the sump and bioplate in the wastewater treatment system, the outer edges of which are formed by stone material of igneous and / or metamorphic rocks, and the inner space is filled with limestone (Pat. RU 2293064, C02F 3/34, 02/10/2007) .

These box-shaped gabion structures do not allow their regeneration when clogged with mechanical particles.

Known containers for forming the walls of a wastewater treatment system, made of elastic tubular knitted fabric by weave cross-dressing, containing weft threads and filled with stone material of igneous and / or metamorphic rocks, the inner space of which is filled with limestone (Pat. 142482, C02F 3/00, 06/27/2014).

Known filter materials made of a plastic frame covered with an elastic tubular knitted fabric of weaving fangs, of which the walls of the filter chambers are made in the drainage and surface drainage cleaning system (Pat. RU 142511, E03F 1/00, 06/27/2014).

The disadvantages of these containers is that it is difficult to regenerate the knitted fabric used, due to the deep penetration of mechanical particles into the knit loops.

The closest are mesh box containers filled with rubber crumb, from which the walls of a bioplate with higher aquatic vegetation are made for wastewater treatment (Pat. RU 149587, C02F 3/34, C02F 3/32, 01/10/2015). The outer edges of the containers are formed by the stone material of igneous and / or metamorphic rocks and are covered with elastic knitwear by interlacing erasers.

The disadvantages of box containers is that it is difficult to regenerate the used knitted fabric, due to the deep penetration of mechanical particles into the knit loops.

The technical result of the proposed utility model is to improve the quality of wastewater treatment.

The technical result is achieved by using a mesh box-shaped container for forming a bioplate wall in a wastewater treatment system containing walls made of stone materials from igneous and metamorphic rocks, covered with elastic knitwear, weaving erasers and filled with rubber crumb 0.5-1.2 microns in size, while the rubber crumb is additionally placed in elastic tubular knitwear by interlacing jacquard.

Placing the rubber crumb in the elastic tubular knitwear by interlacing the jacquard ensures the fixation of the rubber crumb, which facilitates the process of removing it from the container for regeneration and additional filtration of wastewater. Elastic tubular knit jacquard weave is used in the form of a filter material with a variable pore structure, which provides an extremely dense structure with high-quality filtration by reducing permeability, and with a stretched structure, quick and high-quality regeneration.

The interweaving of jacquards, allows to provide the necessary permeability for high-quality filtration, provides two-level capture and retention of mechanical impurities, which is achieved due to the difference in size of the front and back loops. In addition, the implementation of an elastic knitted fabric by interlacing jacquards while maintaining the stretchability of the knitwear in length and width, simplifies and facilitates its regeneration, due to the front loops that perform the function of a prefilter for an extremely dense structure from the wrong loops. Due to this, there is an increase in the productivity of the filtering process and an increase in the quality of liquid purification.

In addition, the process of rubber regeneration, which is located in a container not in bulk but in a tubular knit, is facilitated and accelerated, which in turn increases the efficiency of the filtering process and improves the quality of liquid cleaning.

In FIG. 1 shows a mesh box-shaped container for forming a bioplate wall in a wastewater treatment system, FIG. 2 is a graphic representation of a jacquard weave.

A mesh box container 1, the outer edges of which are formed by stone material 2 of igneous and metamorphic rocks, is covered with elastic knitwear with an eraser weave 3. The inner space of the mesh container is filled with rubber crumb 4 of 0.5-1.2 μm size, placed in an elastic tubular knit with jacquard weave 5.

An elastic knitted fabric by weaving jacquards is obtained by simultaneously knitting inextensible 6, 7, 8 and elastomeric 9, 10, 11 threads on a circular knitted two-knitting machine of class 22 (Multicolor), with tension of an inextensible thread of 12.4 N and an elastomeric thread of 22 N with a depth of cooler 2, 9 mm in the needle cylinder 1.8 mm in the ripple washer. In this case, rows of front 12 and back 13 loops with different density of the loop structure are formed: front loops 12 with low density and back loops 13 with an extremely dense loop structure, which provides different permeability of the layers.

After knitting, the finished elastic tubular knit weave jacquard 5 is filled with crumb rubber 4 and placed in a mesh box-shaped container 1.

A mesh box container for forming a wall of a wastewater treatment system works as follows:

From the mesh box containers 1 form the walls of the bioplate in the wastewater treatment system. With the passage of wastewater through the walls of the bioplate, mechanical treatment of the water occurs, when it passes through the jersey 3, stone material 2 of igneous and metamorphic rocks, elastic tubular jersey by weaving jacquard 5 and rubber crumb 4 with a size of 0.5-1.2 μm. Elastic tubular knitwear interlacing jacquard 5, carries out additional filtration of incoming wastewater, holding mechanical particles up to 0.6 microns in size. Mechanical particles passing through a two-layer structure of knitwear are delayed by front 12 and back 13 loops. Moreover, the front loops 12 perform the function of a prefilter for the purl loops 13, protecting them from clogging by large mechanical particles.

Passing by gravity through the walls of the structure, water enters the bioplate of the system, the walls of which are also formed by mesh box containers 1 and perform the function of mechanical cleaning. After passing through the treatment system, the wastewater can be directed to both chemical and biological treatment (depending on the nature of the pollution of the wastewater and on the further use of treated water).

For regeneration, elastic tubular knitwear by interlacing jacquard 5 with rubber crumb 4 is removed from the mesh box container 1. The rubber crumb 4 is poured out and regenerated by squeezing on presses. When developing a resource, rubber crumb is burned.

Elastic tubular knit weave jacquard 5 stretch in the longitudinal and transverse directions. As a result of this, the front 12 and back 13 loops are stretched and the mechanical particles held by them are released, which are easily removed from the surface of the knitted fabric by a stream of liquid or air. Then the tubular jersey 5 is filled with rubber crumb 4 and placed in the inner space of the mesh container 1.

Thus, the proposed mesh box container for forming a bioplate wall in a wastewater treatment system provides an improvement in the quality of wastewater treatment and the possibility of regeneration of filter materials.
