Abstract

The device relates to techniques for cleaning recycled process water and can be used on horizontal sumps.

The technical result is to increase the efficiency of the device.

This is achieved by the fact that, in a device for cleaning industrial wastewater from a sump, containing a floating water receiver and a spillway device located in the tank of the sump, the floating water receiver is made in the form of floats with a geotextile filter located between them, supported by an arc, one end of which is lowered into water and It is located between the partitions, and the other is led into the spillway device, made in the form of an inclined trough, with one of the partitions mounted on the float, and the other through an arc connected to the water Livni device.

Description

The device relates to techniques for cleaning recycled process water and can be used on horizontal sumps.

A device for dumping industrial wastewater from sedimentation tanks, including a floating water intake in the form of a tray with a flexible hose, connected to the outlet. To increase the efficiency of use by preventing the ingress of suspended matter into the discharged water, the tray is made with an inclined bottom, overflow windows and a drainage tank, and is also equipped with a rotation mechanism and is located along the radius of the sump. (A.S. No. 929153. Class B01D 21/24.).

The disadvantages of the known device, is the clogging of the spillway windows floating on the surface with wood chips and other debris, as well as a significant consumption of electricity needed to rotate the tray. This leads to a decrease in the efficiency of the device.

The closest technical solution for the totality of features is a device for discharging industrial wastewater from the sump, containing a floating water receiver located in the body of the sump in the form of a tray with an inclined bottom and drainage windows, connected to the pipe and mounted to rotate around the water outlet pipe. In order to increase the efficiency of the device, the water outlet pipe is made in the form of two vertical coaxially arranged pipes, the outer one of which is made corrugated and hermetically fixed with the lower part on the inner pipe and the upper one on the tray, while the device is equipped with vertical plates mounted at diametrically located ends tray parallel to its axis, and the tray is made with a Central hole for the release of wood chips, located below the level of the drain windows. (A.S. No. 1717171 class B01D 21/24.).

A disadvantage of the known device is the complexity of the structure made of metal, due to which corrosion of the inner surface of the outlet pipe and corrugated pipe can occur.

The main objective of the utility model is to increase the efficiency of the device.

This is achieved by the fact that, in a device for cleaning industrial wastewater from a sump, containing a floating water receiver and a spillway device located in the tank of the sump, the floating water receiver is made in the form of floats with a geotextile filter located between them, supported by an arc, one end of which is lowered into water and It is located between the partitions, and the other is led into the spillway device, made in the form of an inclined trough, with one of the partitions mounted on the float, and the other through an arc connected to the water Livni device.

In relation to the prototype, the proposed device has the following distinctive features: a floating water intake is made in the form of floats with a geotextile filter located between them, supported by an arc, one end of which is lowered into the water and located between the partitions, and the other is led into a spillway device made in the form of an inclined gutters, with one of the partitions mounted on the float, and the other through an arc, connected to the spillway device.

The geotextile filter, due to the capillary-siphon effect, provides independent lifting and passage of water through the filter. Partitions framing on both sides, the lowered end of the filter into the surface layer of water, ensure its retention in this position. The arc supporting the filter in an arcuate position allows due to its shape to achieve a capillary-siphon effect.

The essence of the device is illustrated by graphic materials, which depict:

Figure 1 - General view of the device, figure 2 presents a section aa in figure 1.

The device located in the sump 1 consists of a geotextile filter 2 located between the floats 3, one end of which is lowered into the surface layer of water, and the other is lowered into the spillway device 4, made in the form of an inclined trough, partitions 5, arc 6.

A device for cleaning industrial wastewater from the sump works as follows:

The device is placed in a sump 1, filled with industrial water from the waste water, and held on the surface by floats 3. Through the end of the geotextile filter 2, lowered into the water and located between the partitions 5, the clarified surface layer of water is absorbed. Water rises and passes through the entire geotextile filter 2, which rests on the arc 6 and due to the capillary-siphon effect at the second end of the geotextile filter 2 flows into the spillway device 4 made in the form of an inclined trough and is removed from the sump 1. The partitions 5 are held on both sides the end of the filter 2, lowered into the clarified surface layer of water, to improve its absorption of water. Finely dispersed soil particles of industrial waste water are adsorbed at the moment of absorption and passage of water through the geotextile filter 2, as a result of which water is purified. During the operation of the device, the geotextile filter 2, which has absorbed a large amount of contaminants, changes to a new one.

The technical result of the claimed device is to provide:

1. Effectively prevent mechanical impurities from entering drains;

2. Water purification from chemical elements by adsorption of the latter on a geotextile material (zeolite fibers can be used as a material).
