Description

The utility model relates to installations for the treatment of storm and sewage from oil products, suspended solids and can be used for the treatment of surface and industrial effluents, as well as in the construction of treatment facilities at car repair plants, gas stations, parking lots, garages and other objects.

A device for cleaning a washing solution from oil products and mechanical impurities, containing a cylindrical housing, in the cylindrical part of which is fixed a partition and a means for collecting and removing oil products, the device is equipped with a pneumatic vibrator, the partition is made in the form of a spiral plate fixed to the brackets, the end of which is connected to means for collecting and removing oil products, made in the form of a branch pipe with a tray for collecting oil products placed inside it, and p a nevovibrator is installed at the bottom of the conical part of the casing [RF Certificate No. 2241, C02F 1/40, B01D 21/24, 1996].

The known device provides cleaning from oil products and oil-containing substances, however, it has insufficient functionality.

A device for cleaning industrial effluents, comprising a housing, sectional with a gap to it and to each other, thin-layer separation units composed of inclined elements with upper and lower guide walls fixed to the walls of the sections, an inlet chamber, an oil pan, a sludge chamber, a clarified liquid chamber, sludge collection area, supply and exhaust pipes, and it is equipped with two vertical partitions installed in the housing in front of and behind the thin-layer blocks on the separation, a stepped partition installed in the gap between the blocks, sections of which are placed with gaps

between each other and made of stepped from removable chambers of paired parts, the elements of which are arranged obliquely alternately in opposite directions from the vertical [RF Patent No. 2060955, IPC 6 C02F 1/40, VO ID 17/02, 1996.]

The known device does not provide the required quality of cleaning from oil-containing substances, have insufficient performance in oil-containing substances, are difficult to manufacture.

A wastewater treatment plant is also known, comprising a receiving tank in the form of a tank with an inclined bottom, a coarse cleaning unit made in the form of a plate thickener and a coalescent oil separator with an inclined bottom, an average cleaning unit in the form of a column filter with a removable cassette, which is connected through an intake chamber and a buffer tank with a fine cleaning unit made in the form of a membrane module with ceramic filtering elements [RF Patent No. 2142424, C02F 1/40, C02F9 / 00, B01D17 / 02, B01D36 / 00, 1999]

The known device is applicable for the treatment of highly contaminated wastewater and irrational for use in the treatment of storm water. In addition, the performance of the installation is insufficient to solve the problems of cleaning storm water.

Closest to the proposed device is a device that contains series-connected with each other in the direction of movement of the processed fluid sedimentation tank - battery, a thin-layer sedimentation unit and a filter element, while the sedimentation tank-accumulator is a tank equipped with means for introducing cleaned effluents and outputting clarified liquid, means the output of sediment and oil-containing substances, the block of thin-layer sedimentation is made in the form of at least one section obliquely placed parallel each other plates mounted on a vertical partition, and the filter element is at least one perforated container filled with a filter load and placed on a solid stationary partition dividing the tank vertically [Certificate of the Russian Federation No. 7115, IPC C 02F 1/40 ; In 01D 21/00; E03F5 / 14, 1998].

The known installation does not provide guaranteed cleaning to the required levels for oil-containing components with significant amounts of storm water.

The objective of the proposed utility model is to improve the quality of cleaning for oil-containing components while maintaining high process performance.

This object is achieved in that the inventive device comprises a settler — an accumulator, a thin-layer sedimentation unit and a filter element located in the tank and connected in series with each other in the direction of the processed fluid, and a coalescer is installed between the thin-layer sedimentation unit and the filter element. Sump - the battery is a part of the tank, the latter is equipped with nozzles for inputting treated effluents and clarified liquids, sediment and oil-containing substances output devices. The thin-layer sedimentation unit is made in the form of at least one section of inclined plates parallel to each other plates mounted on a vertical partition. The coalescer is placed on a continuous vertical partition, made in the form of lattices placed in the housing, and the walls of the housing parallel to each other are perforated. The filter element is at least one perforated container filled with a filter load and placed on solid fixed partitions that separates the tank horizontally. Plant sorbents or activated charcoal can be used as a filter load. The device is equipped with equipment for monitoring the level of petroleum products and a device for collecting them.

The proposed device differs from the known design - the presence of a coalescer and its location.

A comparative analysis of the proposed device with the prototype allows us to conclude that the criterion of "Novelty".

The design of the device is illustrated by drawings.

Figure 1 shows a General view of the inventive device.

The inventive device comprises a reservoir (item 1), a pipe for inputting treated effluents (item 2), a sedimentation tank-accumulator (item 3), a thin-layer unit

sedimentation (pos. 4), placed on a partition (pos. 5), a coalescer (pos. 6), placed on a partition (pos. 7), a filter element (pos. 8), an outlet for clarified liquid (pos. 9), wells (pos. 10) located below ground level, and hatches (pos. 11). The inventive device is equipped with a device for monitoring the level of oil-containing impurities in the form of a sensor (not shown in the drawing), which is connected to the control panel.

The device operates as follows.

From the cleaned area, storm drains with a concentration of petroleum products of 40 mg / l and suspended solids of 500-1000 mg / l enter through the pipe for introducing cleaned effluents (item 2) into the accumulator sump (item 3) and a thin-layer sedimentation unit (item 4) where sedimentation separation of suspended solids and petroleum products takes place. Oil products after separation from the aqueous phase float to the liquid-gas interface and accumulate there. The degree of purification in the volume of the sump accumulator (item 3) from oil products and suspended solids is 70-80%. The degree of purification in the block of thin-layer sedimentation (item 4) is 93-95%. From the block of thin-layer sedimentation (item 4), the effluent goes to the coalescer (item 6), where there is an additional separation of oil products and suspended solids, the degree of purification is 70-85%. At the exit from the coalescer, the residual content of petroleum products and suspended solids is respectively about 0.3 mg / l and 10 mg / l. The final treatment of wastewater is carried out on the filter element (pos. 8), where a sorbent of plant origin or activated carbon BAU-A is used as a filter load. The treated effluents through the outlet pipe are discharged into a fishery pond or other water reservoir for subsequent use.

The inventive device can be manufactured in an industrial environment using standard equipment.

Using the inventive device allows to solve the problem, i.e. to improve the quality of liquid purification from oil products and suspended solids, to expand the technological capabilities of the purification process while maintaining the performance of the process.
