Abstract

FIELD: purification of water solutions from gases. SUBSTANCE: removal of gases which change the quality of potable water, its smell, taste, for removal of manganese, iron, etc. is effected by apparatus having a vertical hermetic body and source of compressed air with diffusers connected to it by two parallel pipelines. Diffusers are located uniformly over body cross section and are spaced from each other. Pressure differential in pipelines is at least 1 atm. EFFECT: high efficiency. 2 dwg, 3 tbl

Description

 The invention relates to structures used for the purification of aqueous solutions of gases, causing changes in the quality of drinking water, smells, tastes, to remove manganese, rhodon, iron, etc.

 A device for water purification by oxidation is known, including a vertical sealed housing and a source of compressed air with diffusers connected to it by means of a pipeline, arranged uniformly over the housing cross section at a distance from each other.

 The purpose of the invention is the increase in the utilization of oxygen of compressed air, mainly of the ozone-air mixture, the intensification of the oxidation process and the optimization of the size of the device.

 In FIG. 1 shows a schematic construction of a reactor; FIG. 2 is a transverse section through a reactor.

 The reactor includes a vertical casing 1 with a bottom made with a slope of 0.15 to the center and a height of the settling part of 1.2 m, a volume of twenty-minute contact of the reaction mixture at a speed of passage of the structure not more than 9 m / h when forced, air, or preferably ozone-air the mixture is supplied through the network 2 in a stepwise manner or through two networks 2a and 2b with different mixture pressures with a pressure drop of at least 1 ata, diffusers 3 installed at 0.2 m from the bottom of the reactor at a distance of no more than 1.2 m from each other the purpose of pumping, the use of oxygen is compressed of air.

 Example. For research we used water from the art well of Romny, Makarov. Large concentrations of pollution were obtained by adding the component of interest to natural water. Reactors such as a vertical sump have proved to be more rational than type water tanks.

 Water analyzes were carried out according to practical manuals of chemical analysis ("Unified methods of water analysis") Edited by Lurie Yu.Yu. M. 1971). For experiments, we used a laboratory centrifuge, AEN-4 microcompressors. The installation was made of plexiglass.

 The research results are given in table. thirteen.

 The experimental data show that the proposed oxidizing reactor allows you to remove a wide range of substances up to 85% of water pollutants from artesian water, but at high concentrations of pollution, but at high concentrations of pollution, the water after the oxidizing reactor must be treated at other facilities.
