OIL POLLUTION CLEANING SYSTEM

IN NERIOD ICE

The proposed utility model relates to the field of sanitary engineering and is intended to prevent the spread of oil pollution under the ice falling into the river, for example, as a result of accidents at oil production and oil refining facilities in the winter.

Known methods and devices for purifying water from oil pollution. In the oil trap, with the help of an air outlet device, a system of partitions and reflective walls, flotation of oil particles and physical release of water from oil pollution occur (Author's certificate No. 835963, С02С 5/00, ЕОВВ 15/04, publ. BI No. 21, 1981) - 1. However, the installation of oil traps in a living stream covered with ice is practically impossible.

There is a method of purification of oily effluents in biological ponds, in which polluted water passing through growing higher aquatic plants in biological ponds is purified from oil oxidized further by microorganisms, in addition to plants, in addition to the physical retention of oil, accelerate its microbiological use (Author's certificate No. 918277, C02F 3/32, publ. BI No. 13, 1982) - 2. This method is effective only during the growing season of plants and is not acceptable in the winter.

For a comparative analysis with the proposed utility model, a system has been adopted for cleaning the watercourse from oil pollution, protected by utility model certificate No. 27930 dated February 27, 2003, ЕВВ 15/04, publ. 02/27/2003, bull. No. 6 - 3. The system contains a deflecting device, a bypass channel, an oil recovery unit associated with an oil storage device, and a bio pond with higher aquatic plants. The deflecting device is configured to follow the water level in the watercourse and create a directed movement of oil pollution

to the bypass channel, in front of the deflecting device, directly inlet of the bypass channel is communicated with the water stream, and after the deflecting device, the output of the bypass channel after the oil recovery unit is communicated with the water stream, and the bio pond is connected to the output of the oil storage device and to the water stream after the deflecting device.

Cleaning in such a system is achieved mainly due to the water biocenosis of the channels located in front of the deflecting device, and an increase in the degree of water release from oil is provided by its four-stage cleaning in the system.

But this system is a stationary structure, here the deflecting device is fixed and can only move in the vertical direction, following a changing water level, and, in addition, in winter the cleaning ability of the biocenosis in canals and biological ponds is very low.

The proposed utility model solves the problem of purifying river water from oil pollution during the period of freezing.

This object is achieved by the fact that in the river purification system from oil pollution during the ice-free period, containing a deflecting device that creates a directed movement of the oil-water mixture into the receiver, and an oil accumulator, a deflecting device is installed with a deepening in the water column in a channel made in ice and connected to the oil-water mixture receiver, which is connected to the river below the channel along its flow by a bottom water outlet, providing the oil-water mixture to the receiver connected to the oil storage connected to nnym overflow river, wherein the deflection device consists of separate L-shaped shields made removable and with the possibility of fixing them to the ice.

The essence of the noble model is illustrated in FIG. 1, where one of the options for its implementation is presented.

elements for attaching shields to ice; 7 - pipeline; 8 - drive, 9 siphon outlet.

On the river, in ice, at an angle of 45 ° to one of the banks, a channel 1 was cut, which was connected to the oil-water mixture receiver 4, connected by a pipeline 7 to an oil accumulator 8, which in turn was connected by a siphon outlet 9 to the river. The deflecting device 3 consists of separate shields 2 made of a L-shaped form, for fixing which there are fastening elements 6 on the ice surface, for example, staples.

On the rivers in places where there is a probability of oil inflow, the elements of the purification system are built, which are necessary in case of oil contamination during the ice-free period, in particular, the oil-water mixture receiver 4 and the oil accumulator 8, as well as the bottom 5 and siphon 9 outlets, as well as pipeline 7. In winter, if oil enters the river in the ice, water is cut through the channel 1 before connecting to the receiver 4, a deflecting device 3 from the Shaped boards 2 is mounted, which are fixed with brackets 6 to the ice on one side and the other side oh deepened in the water column in the channel - the system is ready for operation.

Oil that gets into the river is transported downstream by the flow of water under the ice. Getting into the channel 1, oil pollution along the deflecting device 3 falls into the receiver 4 due to the bottom outlet 5, providing a flow in the treatment system. The upper oil-containing layer from the receiver 4 through the pipeline 7 enters the oil accumulator 8, from which pure water flows through the siphon outlet 9 into the river, and the oil, as it accumulates, is pumped out and sent, for example, by truck for processing.

Thus, a system is proposed for cleaning rivers from oil pollution during the period of freezing, which does not require sophisticated equipment, is simple and reliable in operation.
