Description

A device for wastewater treatment from petroleum products

The utility model relates to devices for wastewater treatment from suspended particles and oil products.

A device for treating wastewater from petroleum products (application No. 97110952/20 (011850) dated 07/02/97. Decision on delivery from 07/28/97). It consists of a horizontal cylindrical body with a lid and an inclined bottom with a nozzle for withdrawing sludge. Coalition modules are installed inside the case. The housing also has pipes for the input of contaminated water, the output of oil products and purified water. The known device allows you to purify water from petroleum products and fine suspended particles.

The disadvantage of this device is that for separation from large suspensions requires preliminary cleaning, i.e. installation of additional equipment is necessary (water must be previously purified from large suspended particles, which requires additional equipment).

A device for wastewater treatment is proposed, which contains a horizontal housing with coalescing modules, nozzles for entering contaminated water, withdrawing oil products, purified water and removing sludge, the case being divided by partitions into three sections: shelf thickener, intermediate section, and oil separator with catalyst models and the sections of the shelf thickener and oil separator are provided with covers and

inclined bottoms. The inclined bottoms of the sections are equipped with nozzles for removing sediment.

The partition wall of the shelf thickener section is provided in the upper part with a gap for liquid overflow, and the oil separator partition in the lower part has a gap with the bottom of the housing.

Figure 1 presents this device. The device is a horizontal cylindrical body (1) with nozzles for the input of contaminated water (2), the output of oil products (3) and purified water (4). Inside the housing (1), partitions (5), (6) are installed, which will press the housing into sections: shelf thickener (7), intermediate section (8) and oil separator (9) with catalytic modules. Shelf thickener and oil separator are equipped with covers (10), (11) and inclined bottoms (12), (13) into which nozzles for sediment removal (14), (15) are integrated.

The device operates as follows: contaminated water is supplied to the housing (1) through the pipe (3). In the shelf thickener (7), water is purified from circular suspended particles that “slide down the shelves down and accumulate in the inclined bottom (12), from which they are removed through the pipe (14). Purified from large suspended particles, water is poured through the baffle (5) into the intermediate section (8), from which through the baffle (6) it enters the oil separator (9) from below. On the coal separator module of the oil separator (9), the oil products are separated from the water. The oil forms a layer on the surface of the water and is discharged through the pipe (3). At the same time, small suspended particles are separated on the modules, which are lowered down, collected in the form of sediment on an inclined bottom (13) and, as they accumulate, are discharged through a pipe (15).

Using the proposed device allows in one device to solve the problem of cleaning from suspensions and petroleum products, which reduces the equipment occupied, and also eliminates the need for additional equipment: pumps, pipes, valves, etc.
