Description

Technical field

The proposed utility model in the form of an electroflotocomine is intended for wastewater treatment from various contaminants.

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, a deep method of wastewater treatment is practically not carried out in these flotation combines, which leads to an insufficiently high degree of wastewater treatment.

The closest technical solution to the proposed utility model is a technical solution in the form of a flotocomine, inside of which there are partitions and a foam chute with a branch pipe for withdrawing foam product into an auger thickener having an external drive, and pipes for supplying working fluid and waste water are installed on the outside of the flotocomine body and a pipe for discharging purified water.

(RF patent №2669842. Flotokombine for wastewater treatment, etc. 17.11.2017, reg. 16.10.2018. Author and applicant B. Ksenofontov - prototype).

A significant disadvantage of the proposed device is the low degree of wastewater treatment, which does not allow for deep purification of wastewater, which, for example, and, therefore, cannot be discharged of purified water into fishery ponds due to the excess of quality standards for treated water for certain indicators.

Disclosure of invention

The objective of the invention is to develop a new design elektroflotokombina, providing a high degree of purification of wastewater from pollution.

The technical result is the implementation of the discharge of purified water into the reservoirs of fishery. The task and the specified technical result are achieved by the fact that the electroflotocombine for wastewater treatment includes a flotocomine, inside of which there are baffles and a foam chute with a branch pipe for withdrawing the foam product into an auger thickener having an external drive, and supply pipes working fluid, wastewater and a branch pipe for treating purified water, and the flotocomine contains a cover, with a flotocomine tank through a branch pipe for treating purified water and a pipeline an electroflotamer is connected, inside which perforated electrodes are installed, located perpendicular to the direction of flow of the treated wastewater with bipolar inclusion, on the outside of the electroflotochamber are located a clean water drain pipe, a sediment discharge pipe to the screw thickener and a foam chute with a foam product discharge pipe to the screw thickener, and the distance between the electrodes is from 0.01 to 0.09 from the height of the electrodes, and the degree of perforation over the living section from 10 to 50%.

The implementation of the invention

The proposed electroflotocomine (Fig. 1) includes a housing 1, inside of which there are partitions 5, and on the outside there are pipes for supplying working fluid 2, wastewater 3, cover 4, foam trough 6 with a pipe for removing foam product 7, and a pipe for removing purified water 8, connected by a conduit 9 to an electroflotocamera 10, on the outside of which a foam trough 11 is installed for the removal of the foam product and its supply by means of a pipe 19 to the inlet pipe 21 of the screw thickener 24, the outlet pipe is clean in rows 13 and outlet pipe 17 precipitate connected conduit 18 conduit 22 supply of sludge in the screw thickener 24. Inside elektroflotokamery provided with perforated electrodes 12 are connected to terminals 14 bipolar current source. At the same time, the distance between the electrodes is from 0.01 to 0.09 of the height of the electrodes, and the degree of perforation, estimated by the live section can be equal to from 10 to 50%. These ratios were established and justified during the pilot tests of the electro-flotator. The foam product discharged through the pipe 7 then passes through the pipe 20 to the screw thickener 24, which has a screw 26 with a drive 23, and also the clarified water is discharged into the collector 25. The condensed product is discharged through the conical outlet pipe 27 to the sediment collector 28 through the pipe 29.

The principle of operation of the proposed electroflotocomine 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. A further process of water post-treatment takes place in an electro-photocamera 10 and from where pure water is discharged through a pipe 13 and 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 20, into the screw thickener 24, into which the foam is blown and gravity from the electroflotocamera 10 through the nozzles 21 and 22, respectively. In the screw thickener 24, the mixture of foam products and sludge thickens, after which the condensed concentrate enters the waste collector 28, and clarified water into the collector 25.

The quality of the clean water obtained, discharged from the pipe 13, satisfies the water quality requirements for discharge into fisheries, and the degree of thickening of the mixture of foam products and sediment makes it transportable with a residual moisture content of 65 to 75%. When using known devices, the quality of the purified does not meet the quality requirements of the water bodies of fishery importance according to most indicators.

The proposed electroflotocombine can be used autonomously as a local treatment plant with an area less than that in the case of using known facilities - analogues up to 1.5-2.5 times.
