Abstract

 A water treatment plant, characterized in that it sequentially treats the source water with ozonation, filtration and UV irradiation according to the following scheme: the source water is pumped through a jet apparatus in which it is mixed with the ozone-air mixture that is sucked from the UV irradiation unit and is generated between the quartz cover and the UV lamp from the air taken from the filter, it enters the contact tank, which is used as the charge volume of the filter, where impurities are oxidized and disinfected, d Lee through the filter loading in the UV irradiation unit where it is finish post-treatment and decontamination.

Description

The utility model relates to multi-stage water treatment methods using ozonation, filtration and ultraviolet (UV) irradiation and can be used to clean and disinfect tap or recycled water in swimming pools to the requirements of SanPin 2.1.41074-01 [1] and SanPin 2.1.2.1088- 03 [2].

The installation is designed for the treatment and post-treatment of drinking water quality tap water of centralized and decentralized water supply, as well as water used in the circulation systems of swimming pool baths.

Processing is carried out in a plant sequentially in 3 stages: ozonation, filtration and UV irradiation.

A schematic diagram of a water treatment plant is shown in figure 1.

The following methods and devices of water treatment closest in technical essence are known, described in sources [3], [4], [5].

Common disadvantages of these objects are the following:

- high power consumption;

- the complexity of the device;

- high overall dimensions;

- the difficulty of automating work processes.

The objective of the utility model is to reduce energy consumption and increase the efficiency of water treatment while reducing the functional unit - the installation of an ozonizer unit.

The technical result of the utility model will take place in the development of a water treatment plant.

The number, purpose and operation of the functional units of the installation provide a complete and comprehensive solution to the task.

The installation can be used for the treatment and post-treatment of drinking water quality of tap water of centralized and decentralized water supply, as well as water used in the circulation systems of swimming pool baths.

The proposed utility model will provide high-quality water purification from pollution with a significant reduction in energy consumption due to the complete rejection of the ozonizer unit. In this case, the UV irradiation unit performs two functions at once: standard - treatment of water with UV rays and additional - the generation of an ozone-air mixture. This solution will significantly reduce the weight and dimensions of water treatment plants, simplify their design and comprehensively automate the work process.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 is a schematic diagram of a water treatment plant. The scheme is made in the form of standardized graphic designations of the elements connected functionally by the lines of movement of the treated water and gases.

The water treatment plant includes the following elements: pump (item 1); inkjet apparatus (item 2); a filter equipped with a float valve (key 3); UV irradiation unit (item 4).

IMPLEMENTATION OF A USEFUL MODEL

The result is achieved by the fact that the water supplied to the treatment undergoes a multi-stage treatment in accordance with the schematic diagram of the water treatment plant shown in Figure 1 as follows.

The source water is taken by the pump (item 1) from the tank of water or a pool bath and fed into the jet apparatus (item 2). Intensive mixing of the treated water with the suctioned ozone-air mixture generated in the UV irradiation unit (item 4) between the quartz cover and the UV lamp from the air taken from the filter (item 3) takes place in the jet apparatus. Next, the water enters the filter’s overload capacity (item 3), where ozone is contacted with water, impurity oxidation reactions and primary disinfection take place. The volume of the overload contact cavity of the filter is maintained constant by installing a float valve that releases the gases released during processing into the UV irradiation unit (item 4). After passing through the filter load, water is supplied to the UV-irradiation unit (item 4), in which it is finished tertiary and disinfected. Further, the treated water is supplied to consumers or enters the pool bath.

Thus, the number, purpose and operation of the functional units of the system provide a complete and comprehensive solution to the task.

The installation can be used for the treatment and post-treatment of tap water of centralized and decentralized water supply to drinking quality, as well as water used in the circulation systems of swimming pool baths.

The proposed utility model will provide high-quality water purification from pollution with a significant reduction in energy consumption due to the complete rejection of the ozonizer unit. This solution will significantly reduce the weight and dimensions of water treatment plants, simplify their design and comprehensively automate the work process.
