Description

(54) APPARATUS FOR CLEANING WASTE WATER AND TECHNOLOGICAL

one

The invention relates to the treatment of wastewater and process solutions containing hardly oxidizable organic compounds.

A known apparatus for the treatment of wastewater and technological solutions, comprising a housing, a filtering element with charging, pipelines for introducing the initial fluid, ozone-air mixture, and draining the purified fluid D-.

The disadvantages of the known device are its intermittent stopping for washing the filter layer from resinous and fat-like substances; the surface of the contact between the components of the contamination and ozone is small.

The purpose of the invention is to increase the efficiency of use by ensuring continuous operation and increasing the contact surface of ozone with soil components.

The goal is achieved by the fact that the filtering element is made Poobraznoy shaped and installed at the bottom of the housing, and the pipeline for introducing the ozone-air mixture is equipped with a cavitation aerator and is located in the contact chamber opposite the pipeline for introducing the source liquid.

SOLUTIONS

In addition, the filtering element is provided with a regenerated load supply pipeline located in its upper part and a contaminated load removal pipeline located in its lower part.

The ozone in the cavitation bubble interacts with the contaminant molecule located 10 s on the surface of the sorbent, thereby increasing the rate of destruction of organic impurities.

The drawing shows the proposed device.

15

The device consists of a housing 1, a filtering element 2 located inside it with a loading 3, forming a contact chamber 4, a pipeline

20 5 for supplying an ozone-air mixture in the upper part of the body, provided with a cavitation aerator 6 located inside it, of the pipeline 7 for supplying the liquid to be cleaned from the bottom

25 parts of the casing, a pipeline 8 for discharging purified water, an assembly 9 for decomposing ozone, pipelines 10 and 11 for supplying and discharging a load.

The operation of the apparatus is carried out

30 as follows.

Sewage fluid is supplied through conduit 7 directly under the blades of the cavitation ionizer 6, it is actively saturated with ozone due to impact contact with cavitation bubbles and then evenly distributed throughout the volume of the contact chamber 4. The ozone-air mixture is supplied through conduit 5 to the discharge zone created during the rotation the impeller of the cavitation aerator, and is transformed by the aerator into fine cavitation bubbles. Some of the organic compounds are destroyed in the contact chamber 4 by the direct interaction of ozone contained in the collapsing cavitation bubbles (1 stage of purification).

Next, the water from the contact chamber is included in the filter element 2, which contains the load (11-111 purification steps). The non-oxidized organic compounds, which are supplied with water from the contact chamber, are first held by the surface of the charge and then destroyed by ozone when the bubble collapses. at the time of their contact with the loading surface.

The operating parameters of the cavitation aerator, the volume of the contact chamber and the volume of the element are calculated in such a way that the contact surface of the slamming bubbles in the contact chamber and the filter element is adjustable. For example, some organic compounds are more actively destroyed at stage II of purification; this requires the supply of more cavitation bubbles to stage II of Pc than at stage I.

The purified water from the housing 1 through the pipeline 8 is supplied to the consumer or to a similar device. Unreacted ozone is piped away from the reservoir through a pipeline for subsequent use in a similar device or it can be decomposed in unit 9, which is a catalyst.

The performance of the proposed apparatus increases about 1.5 times compared with the known, and

(4 cleaning efficiency increases in

 10-20 times.

The economic effect from the implementation of the invention with a capacity of 1000 m / h will be 2 million rubles.
