Abstract

A utility model relates to a drinking water treatment plant. The essence of the utility model is. that the installation contains installed behind the unit for pre-treatment of water from mechanical impurities and in front of the pipeline with the outlet valve and the associated unit for chemical treatment of water.

Description

The utility model relates to the field of water treatment and can be used as a water treatment system for the purification of water coming from a centralized drinking water supply system.

A known installation for the purification of drinking water, containing interconnected piping with an inlet tap, a block of preliminary water purification from mechanical impurities, and a piping with an outlet tap (see Akhmanov, "Water that we drink, St. Petersburg, IK" Nevsky Prospect ". 2002, S.118,125 - analogue and prototype).

A disadvantage of the known installation is the limited operational reliability, lack of disinfection, which is associated with the emergence and reproduction of colonies of microorganisms, and even that. that the filters in it are not subject to regeneration.

The technical result of the utility model is to increase the operational reliability of the process of obtaining benign drinking water for drinking purposes and cooking, due to improved organometric properties, epidemiological safety and harmlessness of the chemical composition of water compared with the hygienic requirements for centralized water supply.

This is achieved by that. that the installation contains installed behind the unit for pre-treatment of water from mechanical impurities and in front of the pipeline with the outlet valve and the associated unit for chemical treatment of water, by removing

free and bound chlorine, chloroform, heavy metals and for disinfecting water.

This is also achieved by the fact that the installation comprises a unit for pre-treatment of water from mechanical impurities and a unit for chemical water treatment associated with it. by removing free and bound chlorine, chloroform. heavy metals for water disinfection, and the block of adsorbed water treatment of activated carbon associated with it and with the pipeline with the outlet valve.

This is also achieved by the fact that the installation contains a unit for pre-treatment of water from mechanical impurities and an associated unit for chemical water treatment by removing free and bound chlorine, chloroform, heavy metals and for disinfecting water. And an adsorption water treatment unit associated with it activated carbon, and a bactericidal block with an ultraviolet lamp with a spectrum of ultraviolet radiation in the range of 200-280 nm associated with it and with the pipeline with the outlet valve.

The essence of the utility model is illustrated in the following drawings, where:

Figure 1 shows the installation for the purification of drinking water assembly, one design.

Figure 2 is also a different execution.

Figure 3 is also. third performance.

Installation for the purification of drinking water contains interconnected pipeline with an inlet tap 1. Block 2 of the preliminary water purification from mechanical impurities, and the pipeline

with outlet crane 3.

The installation contains installed behind the block of preliminary 2 water purification from mechanical impurities and in front of the pipeline with the outlet 3 valve and the associated block 4 for chemical water purification by removing free and bound chlorine, chloroform, heavy metals and for disinfection of water. (figure 1).

The installation in another design (figure 2) contains installed behind the block 2 pre-treatment of water from mechanical impurities and associated unit 4 for chemical treatment of water by removing free and bound chlorine, chloroform, heavy metals and for disinfection of water, and associated with him and with the pipeline with the outlet valve 3 block 5 adsorption treatment of water with activated carbon.

The installation in the third version (Fig. 3) comprises a unit 4 for pre-treating water from mechanical impurities and a unit 4 for chemical water treatment, by removing free and bound chlorine, chloroform, heavy metals and for disinfecting water, and associated with block 5 adsorption treatment (water activated carbon, and associated with it and with the pipeline with the outlet valve 3 bactericidal block 6 with an ultraviolet lamp with a spectrum of ultraviolet radiation in the range of 200-280 nm.

Installation for the purification of drinking water operates as follows.

Water intake is carried out from the centralized water supply system by opening the inlet tap 1. The initial liquid - water, passes through the cartridge of the block 2 of preliminary water treatment. where water is purified from mechanical impurities - rust, sand, clay and other suspended particles with a size of more than 0.25 microns.

Next, the water enters block 4 for chemical treatment of water. where water is purified from free and bound chlorine, chloroform, heavy metals, for example, lead, iron. mercury, arsenic, due to electrochemical oxidative processes in the environment of the CDD. In the same block 4, water is disinfected in KDF-55 medium.

After passing water through block 4, purified drinking water (FIG. 1) can be used for drinking purposes and cooking.

To improve the quality of water purification and improve its aesthetic properties, block 5 is connected to the block 5 of adsorption water purification with activated carbon, it improves the taste of water and its organoleptic properties. Activated carbon also eliminates possible organic impurities in water and reduces the concentration of heavy metals and radionuclides, (figure 2)

If necessary, significantly increase the level of disinfection of drinking water, block 5 is connected to block 6 with an ultraviolet lamp with a spectrum of ultraviolet radiation in the range of 200-280 nm.

After the passage of block 6 (Fig. 3), water through the pipeline with the outlet 3 tap enters the consumer.

The obtained drinking water is epidemiically safe, and is suitable for use in the catering unit of the preschool institution where the installation ("Silver Stream"), made in accordance with figure 1, is installed.

Thus, drinking water that has passed the above water treatment system fully meets the criteria for favorable organoleptic properties, epidemiological and radiation safety, chemical composition harmlessness and stably maintains its high drinking properties, and meets all hygiene requirements for drinking water for drinking purposes and preparation write.

industrial applicability.

The utility model can be used in installations for the purification of drinking water.
