Description

Technical field

The proposed utility model in the form of a deminoflotocomine is designed for wastewater treatment from various contaminants, including dissolved salts.

State of the art

There are various flotation combines for wastewater treatment, in which the processes of water purification and thickening of sediments are simultaneously carried out (RF Patent for Utility Model No. 170182. Flotokombine for wastewater treatment, etc. 07.25.2016, reg. 04/18/2017. Author and applicant Ksenofontov B .FROM.

RF patent No. 26658411. Flotocomine for wastewater treatment, etc. 04/11/2017, reg. 06/21/2018. Author and Applicant Ksenofontov B.S.).

At the same time, the required degree of wastewater treatment is not achieved in these flotation combines.

The closest technical solution to the proposed utility model is a technical solution in the form of a flotokombine, including a housing, inside of which there are partitions, and pipes for supplying working fluid, wastewater, a cover, a foam chute with a pipe for removing the foam product, and a pipe for cleaning the outlet are installed on the outside water, foam product, discharged through the pipe further through the pipeline to the screw thickener having an external drive (RF Patent No. 2669842. Flotokombine for wastewater treatment, p b. November 17, 2017, reg. 10/16/2018. Author and applicant B.S. Ksenofontov - prototype).

A significant disadvantage of the proposed device is the low degree of wastewater treatment, which does not allow, for example, to dump purified water into reservoirs of fishery value.

Utility Model Disclosure

The objective of the utility model is to develop a new design of the deminoflotocombine, providing a high degree of wastewater treatment from pollution.

The technical result is to increase the efficiency of wastewater treatment with achieving water quality, which allows for the discharge of treated water into reservoirs of fishery value.

The task and the specified technical result are achieved by the fact that the deminoflotocombine for wastewater treatment includes a housing, inside which there are partitions, and on the outside there are nozzles for supplying working fluid, wastewater, a cover, a foam chute with a pipe for removing the foam product, and a branch pipe for cleaning water, foam product, discharged through the pipe further down the pipe into the screw thickener having an external drive, characterized in that in order to increase the cleaning efficiency wastewater the purified water pipe is connected in series with the cation-exchange and anion-exchange filters, and the ion-exchange nozzle in them is located between the electrodes connected to an alternating current source, and mesh electrodes with square cells from 3 to 10 mm in size are used.

Utility Model Implementation

The proposed deminoflotocombine (Fig. 1) includes a housing 1, inside of which there are partitions 5, and on the outside there are installed pipes, respectively, for supplying a working fluid 2, wastewater 3, a cover 4, a foam trough 6 with a pipe for removing foam product 7, a pipe for removing purified water 8, connected by a pipeline to cation-exchange filters 9, inside which a cation-exchange nozzle is placed between the mesh electrodes 10 with square cells with a square side of 3-10 mm, and the outlet pipes of which are connected to a daily reservoir 11 from which the water to be purified is pumped through the pump 12 to the anion exchange filters 13 with mesh electrodes 14 placed between them, between which there is an anion exchange nozzle with square cells with a side of a square of 3-10 mm, connected to a collection of purified water 15 having the outer side of the outlet pipe for purified water 16. Data on the shape and size of the cells were installed and justified when conducting model tests of the deminoflotocombine. The foam product discharged through the pipe 7 further through the pipe 19 through the pipe 18 enters the screw thickener 22 having a drive 17, as well as the clarified water outlet pipe 20 sent to the collector 21. The condensed product is discharged through the conical outlet 23 to the sediment collector 24 through pipe 25.

The principle of operation of the proposed deminoflotocombine is as follows. Waste water through the pipe 3, and the working fluid through the pipe 2 enters the housing 1, where the combined flotation process of preliminary water treatment takes place. The further process of purification of water from dissolved salts, namely from cations, takes place in a cation exchange filter 9, with one filter in operating mode and a second filter in regeneration mode, and then the extraction of anions in the anion exchange filter 13 from anions. In this case, one filter from the group of anion exchange is operated, and the second is regenerated. The intensification of ion exchange processes is achieved by applying an alternating electric field to the ion-exchange nozzle in cation-exchange filters to the cation-exchange filters, and in anion-exchange ones, respectively to the anion-exchange nozzle, by supplying power to mesh electrodes with square cells with a side size of 3 mm to 10 mm. The selection and justification of these sizes was made on the basis of experimental studies.

Then, purified, including from salts, water enters the collection of clean water 15 and is used for its intended purpose.

The foam product formed during the combined flotation process of water purification from the foam trough 6 enters through the nozzle 7 and pipe 19 into the screw thickener 22, in which it thickens, after which the concentrated concentrate enters the sediment collector 24, and the clarified water into the collector 21.

The quality of the pure water obtained, taken from the collection 15, meets all the water quality requirements, including for dissolved salts, for discharge into fishery reservoirs, and the degree of condensation of the sediment makes it portable with a residual moisture content of 65% to 80%, and when used known devices, the quality of the purified does not meet the quality requirements of the water of reservoirs of fishery importance in a number of ways.

The proposed deminoflotocombine can autonomously be used as a local treatment plant with an area less than in the case of using facilities - analogues up to 1.5-2.0 times.
