Abstract

The invention relates to wastewater treatment devices containing petroleum products and suspended solids, and can be used to clean up wastewater from carwash. The purpose of the invention is to increase the cleaning efficiency. A device for purifying water from oil products and solid particles contains a cleaning chamber with a tray for collecting surfaced pollutants connected to the separation of water aftertreatment from oil products, an oil receiving tank, a settling chamber, a sludge collector and a drainage pipe for purified liquid and oil products. The conical bottom of the after-treatment section is in communication with a removable granular filter, the outlet of which is connected to the cleaning chamber. At the bottom of the cleaning chamber and the remaining chamber are perforated screens and inclined flow guide plates. The oil receptacle is equipped with a vertical pipe with a restrictive washer with a limit switch and a float and a pump electrically connected to the limit switch. 2 Il.

Description

The invention relates to wastewater treatment devices containing petroleum products and suspended solids, and can be used to clean wastewater from carwash, railway and air transport.

The purpose of the invention is to increase the cleaning efficiency.

Figure 1 shows the proposed device, a longitudinal section; FIG. 2 shows the node I in FIG. one.

The water treatment apparatus comprises a receiving funnel 1 with a tray 2 having a transverse protrusion 3 at the end and connected to the inlet 4 of the cleaning chamber 5. In the upper part of the chamber, 5 cleaning, a tray 6 is placed for collecting floating contaminants with a flexible part 7 and a longitudinal plate 8 with a float 9. Tray 6 for collecting floating contaminants is connected by a splash pipe 10 with the separation 11 of water aftertreatment from dairy products having conical bottom 12. The device contains a removable granular filter 13, the inlet of which is connected to the bottom 12 of the after-treatment section, and the outlet is connected via a pipe 14 to the cleaning chamber 5. The water purification unit 11 from the oil products through the hole 15 communicates with the oil intake container 16, in which the vertical pipe 17 is placed with the restrictive washer 18 and the ring float 19 and the limit switch electrically connected to the pump 20. The purification unit has a hatch 21 and a lifting mechanism 22 to replace the filter 13.

The cleaning chamber 5 in the lower part communicates with the settling chamber 23. In the chambers 5 and 23 there are perforated screens 24 and inclined flow-guiding transverse plates 25. The cleaning chamber 5 and the settling chamber 23 are made in the form of vertical tanks with curved bottoms 26 fitted with V -shaped sediment collection chambers 27, having vertical cylindrical ducts 28 with a slit outlet nozzle 29, doors 30 with floats 31 hinged at the bottom of the ducts, and sludge withdrawal pipelines 32 communicating with the sediment collector 33. The box 28 is made with sides 34, under which are installed the sensors 35,

In the lower part of the collection of 33 sediment placed removable granular filter 36 with pipe 37 drainage of the clarified liquid. In the side wall 38 of the sediment collector there is a tire 29 in which a float 40 and a limit switch 41 are installed, electrically connected to the filter lifting mechanism 42.

The device works as follows.

Sewage water contaminated with oil and earth flows by gravity into the funnel 1 and through the inclined channel with the oil film that has emerged floats onto tray 2, where, striking the protrusion 3, raises the float 9 adjusted to a certain depth of oil film removal by the plate 8. The separated oil and part of the water through the tray 6 and the nozzle 10 is discharged into the water purification unit 11 from the oil products, where the oil is separated from the water and the overflow enters through the opening 15 into the oil receiving tank 16. When the annular float 19 is raised pump 20 and a vertical pipe 17, the oil is removed. Water, as more heavy, goes down and is filtered on the filter 13 and through the pipe 14 enters the cleaning chamber 5.

In the purification chamber 5, water containing solid particles falls on a perforated screen, where, breaking up into streams, it is saturated with oxygen. The passage of the flow-guiding transverse plates 25, the water is cleaned from solid particles that fall into the box 28. Circular rims 34 of the box 28 are restrictive for sensors 35. Through the slit outlet 29, the solid particles fall to the bottom of the V-shaped chamber 27 to collect sludge and when the pulp begins to accumulate on the inclined hinged doors 30, the floats 31, unable to withstand the weight of the pulp, open the doors 30, including the sensors 35, which include the sludge discharge pipelines 32. The precipitate is pumped to sediment collector 33, from where it is removed by any known method.

In order to guarantee cleaning, before draining the discharged liquid, the waste liquid will carry out additional purification in one more step on filter 36, which is similar when it enters the cleaning chamber 5 from water after-treatment section 11. Water through pipe 37 is discharged into the sewer.

The use of the proposed device provides effective water purification from petroleum products with an uneven supply of the initial liquid.
