Description

Compact modular drinking water treatment plant

The claimed technical solution relates to installations for purifying groundwater from iron, manganese and other metals while removing hydrogen sulfide and other harmful gases to produce environmentally friendly drinking water.

A device for cavitation disinfection of natural and wastewater without the use of chemicals is known from the prior art. Patent RU No. 2396216 IPC C02F 1/34 publ. 08/10/2010, comprising a housing in which a sleeve with eight longitudinal channels is installed with swirling devices placed in them in the form of screw flow formers providing twisting, acceleration of flows and cavitation. At the exit of the channels, an acoustic pulsation chamber is placed, in which, when cavitating flows oscillating with the same frequency interact, acoustic resonance excitation arises. The technical result of the invention is to increase the efficiency of the device for disinfecting water due to the acoustic resonant excitation of cavitating flows.

This method cannot be applied without additional subsequent water purification when treating natural water intended for drinking purposes.

A known installation for flotation water treatment, containing a closed hydraulic line with sequentially connected the main flotation chamber, one or more additional flotation chambers, a recirculation water pipe having a pump with an air ejector and a saturator, the supply of purified water, characterized in that each previous flotation chamber is connected followed by a chamber by means of a liquid-liquid ejector, the carrier fluid inlets of which are connected in parallel to the ca output uratora, wherein the recirculation water conduit coupled to the primary flotation chamber equipped with ezhektrom type "liquid-liquid" resorbed fluid input of which is connected with a supply of treated water patent RU 2107032 6 IPC C02F 1/24, publication date 20.03.1998).

The main disadvantage of similar devices is the insufficiently high degree of water purification, both from iron and hardness salts.

Known devices for deferrization of groundwater, which provide for the preliminary treatment of water by aeration or reagents, oxidizing agents and subsequent filtering (Building codes and rules. Water supply. External networks and structures: SNiP 2.04.02-84: introduced 01.01.86. - M. : Stroyizdat, 1985. - P. 43. Kulsky L.A., Strokach P.P. Technology of natural water treatment. - Vishcha school, 1981 - S. 213-221.)

The main disadvantages of these devices are:

1) restrictions related to the content of total and ferrous iron in the source water, pH, alkalinity, and others (Building codes and rules. Water supply. External networks and structures: SNiP 2.04.02-84: introduced 01.01.86. - M. : Stroyizdat, 1985. - S. 43.);

2) the bulkiness of structures, high construction costs and high operating costs;

3) poor process control.

Other devices are known (RU Patent No. 2136601, IPC C02F 1/46, publ. 1999.09.10 and RU Patent No. 2136600, IPC C02F 1/49, publ. 1999.09.10), in which ozone is effectively used to disinfect water, however due to the fact that ozone quickly decomposes in water, it is also chlorinated before water is supplied to the water supply network to prevent the re-development of bacteria (book of the authors L. Kulsky, MN Bulava, etc. "Design and calculation of water treatment facilities," Kiev, 1972, p. 198-202).

Other methods and devices used for disinfecting water, for example, treating water with chlorine using special chlorination apparatus, in which the prepared chlorine water is then mixed with the entire mass of incoming water.

The disadvantages of treating water with chlorine are that chlorine must be stored in steel cylinders in consumable warehouses, designed in accordance with the sanitary rules for warehouses of potent toxic substances (SDYA), before consumption, which requires high capital costs.

Water treatment plants are no longer able to prevent a significant amount of inorganic and organic substances from entering the drinking water. Under these conditions, the widespread use of chlorine as a disinfectant leads to the formation of new compounds, often more toxic than the original ones. It has been established that when chlorine is treated with water, halogen-containing compounds are formed, most of which have mutagenic properties, and some of them are carcinogenic to humans (Goncharuk V.V., Potapchenko N.G., Vakulenko V.F. "Ozonation as a preparation method drinking water: possible by-products and toxicological assessment ". Chemistry and technology of water. - 1995, v. 17 - No. 1).

For example, chlorination of water containing phenol enhances the smell of water as a result of the formation of chlorophenols, the threshold concentration of which is 1000 times higher than phenol itself.

Closest to the proposed invention is a method of water treatment, including purification of water obtained from a well, from mechanical impurities, from suspended particles and dissolved organic substances at a deferrization station, softening water at a softener, and further cascading filtration through a bulk filter system and irradiating it with light in ultraviolet region of the spectrum at the output, (RF patent No. 2448914 C02F 9/12, C02F 1/28, publ. 04/27/2012)

The disadvantages of the prototype system are the lack of quality control of water at various points of the technological scheme and, accordingly, the inability to control the operating modes of the installation based on data on the content of pollutants in the treated water.

The task to which the claimed technical solution is directed is to expand the arsenal of existing technical means of a certain purpose in this area by significantly increasing the efficiency of the process of preparing drinking water.

This problem is solved due to the fact that the claimed compact modular installation for drinking water purification pumps cleaned water in cavitation mode through a hydrodynamic device, through an angular screen filter, an automatic deferrization filter, an ultraviolet water disinfection unit and an automatic lighting-sorption filter connected by a piping system with inlet, outlet and drainage collector.

The modular drinking water treatment plant can be equipped with a static cavitator. The deferrization filter and the charcoal filter can be equipped with an automatic valve to control the unit's operation modes based on the data on the content of pollutants in the treated water.

The technical result provided by the given set of features is to improve the quality of natural water that meets all the rules and regulations of SanPiN 2.1.4.1074-01 "Drinking water and water supply to populated areas" with automatic control of the cleaning process.

In FIG. Figure 1 shows a general view of the Compact Modular Potable Water Treatment Plant. It contains a static cavitator 1, an automatic deferrization filter 2, and an activated carbon sorption purification unit 4, which are equipped with an automatic control and control unit 5, an ultraviolet disinfection unit 3, a pipeline connecting the drinking water purification system 6.

Installation works as follows:

Water from a surface or underground source of water supply through a pipeline - through the inlet pipe is fed to a static cavitator, in which cavitation or hydrodynamic (also called hydro-microwave) treatment of natural waters takes place. The static cavitator provides dispersion, as a result of which there is intense homogenization, effective oxygen saturation of the water with a simultaneous disinfection effect, in the zone of cavitation collapse of the bubbles, the process of intensification of physico-chemical interactions and disinfection of water occurs. It is connected to an automatic deferrization unit, which contains a piping system with an inlet, outlet and drainage collector, through an angled screen filter, where mechanical treatment of the incoming water takes place. The manganese, iron, and hydrogen sulfide removal unit is an automatic deferrization filter in which water passing through a filtering medium that serves as an oxidizing agent is freed from hydrogen sulfide, iron, and manganese dissolved in water (which transform into an insoluble form and precipitate). The precipitate is retained in the filter loading layer and subsequently washed into the drain during backwash. After developing the capacity of the filter load, regeneration is carried out by loosening and then slowly pulling a solution of potassium permanganate through the filler. After bringing the content of dissolved substances to the maximum allowable concentrations, water is irradiated with light in the ultraviolet region of the spectrum. For disinfection, in the conduit 3, which is a pipe, the inner wall of which has a reflective coating for UV radiation, a stream of water enters, which is exposed to UV radiation from light-emitting diodes in the UV range. With such irradiation of water, along with saturation with active oxygen due to ozonation of oxygen dissolved in water and photolysis of water with the formation of hydrogen peroxide, its disinfection also occurs. Further, the water passes through the Automatic carbon clarification sorption filter for backwash water purification, designed to remove organic impurities, and to correct organoleptic indicators (unpleasant taste, smell, taste).

In accordance with the technological regulations for the operation of the device, the following settings have been introduced into the automatic control unit:

- daily schedule for ensuring the costs of purified water supplied to consumers;

- the frequency of switching from deferrization modes to washing modes and vice versa;

- control algorithms for all electrified valves are compiled according to the results of prestarting tests.

The advantages of the claimed block-modular installation for purification and water supply:

high quality purification of natural drinking water;

compactness;

automation of the process of purification and water supply, which does not require the constant presence of maintenance personnel.
