Description

Technical field

The proposed utility model in the form of a chemical flotator is designed 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 B. Ksenofontov).

Moreover, in these flotation combines there is practically no effective way of chemical treatment of wastewater, for example, using strong oxidizing agents, such as ozone, hydrogen peroxide, etc., 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 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, etc. 11/17/2017, reg. 10/16/2018. 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 example, to dump purified water into reservoirs of fishery importance for all standardized indicators.

Utility Model Disclosure

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

The technical result is to increase the efficiency of wastewater treatment with the achievement of water quality, which allows for the discharge of purified water into reservoirs of fishery importance in accordance with all standard indicators.

The task and the specified technical result are achieved by the fact that the chemical flotator for wastewater treatment includes a housing, inside which there are partitions, and pipes for supplying working fluid and wastewater are installed on the outside, as well as a branch pipe for removing pre-treated water, while the chemical flotator includes a foam chute with a pipe for withdrawing foam product through a pipeline into a screw thickener having an external drive, and an ejector is installed in front of the pipe for supplying wastewater reagent supply, moreover, the chemical flotokombine is equipped with a lid, and the nozzle for supplying the working fluid is additionally connected to an ejector for supplying ozone, and at the same time, the nozzle for removing pre-treated water is connected via a pipe to a chemical reactor, the outlet nozzle of which is connected to a grain filter with a discharge nozzle into the tank, and, in addition, after the branch pipe for the removal of previously purified water, an ejector is installed in front of the chemical reactor to supply an oxidizing solution at an equal distance between the branch pipe dvaritelno purified water and the chemical reactor.

Utility Model Implementation

The proposed chemical flotation harvester (Fig. 1) includes a housing 1, inside of which partitions 9 are located, and a pipe for supplying a working fluid 2 with an ejector 4 installed in front of it with an ozone supply pipe 3, a waste water supply pipe 7 with a front ejector 5 mounted thereon, is installed on the outside; with a nozzle 6 for supplying a reagent, for example, a coagulant or flocculant solution, a lid 8, a foam trough 10 with a nozzle for withdrawing a foam product 11, a nozzle for removing purified water 12, with a chemical reactor 15 installed in the middle between it zhektor 13 with a nozzle 14 for supplying an oxidant. In this case, the chemical reactor 15 is connected by means of a pipe 16 to an intermediate tank 17, from which the water to be treated is supplied to a grain filter 19 by means of a pump 18, connected by a pipe 20 to a purified water collector 21 having a purified water outlet pipe 22 on the outside. the product discharged through the pipe 11 further through the pipe 25 through the pipe 24 enters the screw thickener 28 having a drive 23, as well as a pipe 26 for outputting clarified water directed to the collector 27. The condensed product through a conical outlet cartridge 29 side is given to the collection of sludge 31 through the pipe 30.

The principle of operation of the proposed chemical flotation combine is as follows. Wastewater through nozzle 7 pretreated with reagent introduced into wastewater through nozzle 6 of ejector 5, and the working fluid mixed with ozone supplied through nozzle 3 of ejector 4 and then passing through nozzle 2 enter the housing 1, where the combined flotation the process of pre-treatment and disinfection of water. A further process of water purification takes place in a chemical reactor 15, into which the water to be purified enters through an ejector 13 with suction through a pipe 14 of this ejector of an oxidizing agent solution, for example, for example hydrogen peroxide. In this case, the ejector 13 is installed in the middle of the distance between the pipe 12 of the outlet for purified water and the chemical reactor 15. Next, the purified water enters the collector of pure water 21 and is used for its intended purpose. The foam product formed during the combined flotation process of water purification from the foam trough 10 enters through the pipe 11 and pipe 25 into the screw thickener 28, in which it thickens, after which the concentrated concentrate enters the sediment collector 31, and the clarified water into the collector 27.

The quality of the clean water received from collection 21 satisfies the water quality requirements for discharge into fishery reservoirs according to all standardized indicators, and the degree of thickening of the sediment makes it portable with a residual moisture content of 67 to 75%, and when using known devices, the quality of the purified water does not satisfy the requirements water quality of reservoirs of fishery importance according to most indicators.

The proposed chemical flotator can be used autonomously as a local treatment plant with an area less than in the case of using facilities - analogues up to 2.2-2.5 times.
