The invention relates to the treatment of industrial wastewater and the use of ssets, H & t example, in enterprises carrying out the removal of petroleum products from industrial wastewaters.

j A well-known oil trap for trapping fine particles of petroleum products,: containing a housing with devices for supplying and discharging phases, flat inclined shelves, to the side edges of which there are vertical partitions adjoining the oil drainage channels. One-t coarse-grained particles are removed by the flow of purified water in the direction of its movement from the surface of the shelves, a mine of a bone; | Well accumulation, which leads to deterioration | the efficiency of the oil trap .;

 In order to increase the efficiency of the eye, drains waste oil from petroleum products | In the proposed oil trap, the shelves are strewn with grooves located on their end sections and with a slant towards their middle. {

FIG. 1 shows the proposed (petroleum trap, longitudinal section; FIG. 2, section A-A in FIG. 1; FIG. 3, a schematic of the end portions of the flat shelves with transverse grooves.,

 The oil trap has coarse wire 1, input weir 2, distribution, partition 3, flat shelves 4 with cross-sections and elobami 5, channels 6 are vertical, adjacent to the end sections-i stacks of flat shelves 4, oil-collecting 7, oil retaining wall 8, outflow spillway 9 and discharge pipe 1O.

 The oil trap works as follows. Sewage water containing oil-containing products and ducts is supplied through the supply pipeline 1 through the inlet weir 2 and the distribution partition 3 to flat

4 and inter-shelf space. People 4 BCnnia oil particles on the bottom surface of flat polos || 4 and drift along their surface by the flow of the cleaned fluid into transverse chutes w and they are removed beyond the boundaries of the second "9 g of the trunk to the vertical channels 6 and further to the station, where they are periodically sent down oil traps.
