Description

The invention relates to the field of ecology, in particular to the technology of purification and disinfection of natural waters in the process of water treatment and physico-chemical wastewater treatment from toxic compounds of natural and technogenic origin using different types of coagulants, and can be used to improve the condition and maintain human health and environmental protection, and can also be attributed to the priority strategic direction of the development “Health of the nation”.

State of the art

The prior art methods for producing coagulant for the purification of natural and waste water. Coagulants are known, the most widespread of which are coagulants containing aluminum, in particular aluminum sulfate, aluminum oxychloride and sodium aluminate, of which aluminum sulfate is most often used (1) for the purification of natural and waste water. However, these coagulants do not achieve a high degree of purification and disinfection of natural and waste waters; their main disadvantage is a significant amount of residual aluminum in purified water.

Known coagulant based on aluminum (2), which is a calcium hydrocarbon aluminate in the form of a homogeneous gray-white powder. Calcium hydrocarboaluminate is obtained as a by-product of the production of alumina by the method of hydrochemical synthesis from alkaline carboaluminate solutions and lime in the complex processing of nepheline. However, the high cost of nepheline, which is rarer in nature than, for example, bauxite, affects the high cost of the coagulant itself. In addition, the intermediate product (white sludge), from which calcium hydrocarbon aluminate is obtained, is used mainly in the production of alumina for desalination of aluminate solutions. In this regard, alumina refineries are not interested in the production of this coagulant.

A known composition of granular material (3) containing a catalyst based on Μη (II) and an adsorbent based on oxides of iron, magnesium, manganese and silicon. However, the known composition does not have a sufficiently high ability to disinfect and discolor the treated water.

Known coagulant for treating industrial wastewater using coagulants (4) containing natural aluminosilicate, having in its composition a ratio of silica to alumina 3.9-4.16 and a ratio of natural aluminosilicate to mineral acid in a ratio of 0.07-0, 25. However, the known coagulant has an insufficiently high degree of purification.

A known method for producing coagulant of aluminum sulfate from aluminum hydroxide, which is based on the decomposition of aluminum hydroxide with sulfuric acid and crystallization of the resulting product (5, p. 48-53). However, this method requires an expensive and scarce starting material of aluminum hydroxide, which is an intermediate in the production of alumina.

Known methods for producing coagulants from bauxite, kaolin, clay and other minerals containing aluminum, the essence of which is the decomposition of these minerals with sulfuric acid, followed by crystallization of the finished product (5, p. 53-79). However, these methods are complex and time-consuming.

A known two-stage method for producing a coagulant based on aluminum hydroxychloride (6) with sufficiently high cleaning properties. However, it is time-consuming and expensive, and also not always reliable in obtaining such a coagulant, which would have constantly high and stable cleaning and disinfecting properties.

A known composition for treating wastewater in order to remove colloidal solid particles (7). Common is the use of the composition for wastewater treatment and for the removal of soluble phosphorus compounds. However, the known composition does not solve the technical problem, which is set in the claimed invention: purification of natural water to drinking quality. In the known invention uses dump red mud, which contains toxic impurities that are not removed in the synthesis process; aggressive media are used (sulfuric and hydrochloric acids), as a result of which aluminum-alum and active silicate gel are formed during processing; the invention has a narrow pH range; other qualitative composition and other differences from the claimed coagulant.

A known method of purification of water containing suspended or dissolved organic and / or inorganic substances by precipitation of ίη 8 and oxidized titanium compounds (8). Signs common with the claimed invention include: the content of compounds of four valence titanium and the possibility of containing an additional coagulating agent in the form of a trivalent aluminum salt and flocculants. However, in the known method, the introduction of an acidic coagulant necessitates the neutralization of purified water, and the use of titanium (III) compounds as a coagulant requires additional treatment of the purified water with oxidizing agents, which renders the known method unsuitable for purifying natural water to potable quality.

Known technologies for water purification that use different coagulants in different combinations, including flocculants and opacifiers (9). In contrast to the technologies described in this review (9), the claimed invention proposed a fundamentally new composition of titanium coagulant, its production method and technology of use.

- 1 011441

A known composition for wastewater treatment from toxic compounds containing compounds of tetravalent titanium and its mixtures (10). In the well-known invention, in contrast to the claimed one, a different composition, a different method of its production, and the main one - toxic substances are contained in the final product according to the known technology, which significantly narrows the scope of its application to wastewater and does not allow, in accordance with existing standards, quality assessment drinking water, use well-known technology to purify natural waters to drinking quality.

A known method of producing reagents, which contains compounds of titanium and aluminum and is intended for the treatment of natural waters (11). However, the composition of the known coagulant includes a large amount of magnesium and iron, and the treatment is carried out with an acidic titanium-containing solution with heating, and the coagulant is introduced in the form of a gel. Different starting materials and different production technologies of the composition also affect the final result - the quality of natural water treatment.

A coagulant is known for the purification of natural waters (12), however, the quality of drinking water obtained is unstable; it has a different composition with the claimed invention, different starting ingredients and a different method for its preparation.

Known coagulant having a composition close to the declared coagulant content of aluminum and titanium (13). However, the known coagulant is intended only for wastewater from paper mills, and not for the purification of natural water to a drinking level.

A known method for producing a coagulant and a method for using a coagulant for cleaning and disinfecting natural and waste waters, closest to the proposed method according to the achieved technical result and selected as a prototype (14). The coagulant contains compounds of aluminum, calcium oxide, silicon oxide, iron oxide, magnesium oxide and sulfur dioxide. This method is environmentally friendly in the production of coagulant for the purification and disinfection of drinking water.

The disadvantages of the known method of producing coagulant for the purification of natural and wastewater are its high cost and scarcity, since nepheline, which is more rarely found in nature than, for example, bauxite, is used as its mineral, which affects the high cost of the resulting final product, those. the known method (as a whole) is referred to as a rather laborious and expensive technology.

Methods for using a coagulant are also known in the art.

A known method of using a coagulant for purification of natural and waste water, which is closest to the proposed method and adopted as a prototype (5), is based on the manufacture of an aqueous suspension of the obtained coagulant and its mixing with purified water at a fixed time during which cleaning and disinfection occurs.

The disadvantages of this method are the insufficiently high efficiency of water treatment at low temperatures, the likelihood of corrosion activity of water, as well as the salt background of the treated water. All these factors, in general, lead to a reduction in the service life of networks and water pipes and a decrease in their throughput.

According to the results of the studies given in table. 16-18, it follows that the value of the optimal dose of titanium coagulant in water treatment technologies largely depends on the level of pollution of natural water. The results of numerous studies have shown that the claimed titanium coagulant can provide effective disinfection simultaneously with a high degree of water purification for a sufficiently long time. The duration of the disinfecting effects of the claimed titanium coagulant is determined by the magnitude of the administered dose of titanium coagulant. The test results confirmed that the ingredients of the new titanium coagulant and their ratio are chemically resistant compounds in a wide range and provide a long-term disinfecting effect.

Example 16

As can be seen from the test results of the claimed titanium coagulant, after 30 minutes of exposure, there is a sharp decrease in the concentration of rotaviruses - by one order of magnitude, then, almost after exposure to 30 minutes of contact with the claimed titanium coagulant, the infectious activity of rotavirus was completely suppressed. By way of illustration in FIG. 1 and 2 show electron microscopy images obtained from studies of virus-containing preparations, in particular feces of a child with acute gastroenteritis (scale interval - 100 nm) before (Fig. 1) and after (Fig. 2) contact with the titanium coagulant under test. In FIG. Figure 2 clearly shows that under the influence of a coagulant of a titanium particle, rotavirus lost the outer protein membrane.

Analysis of the obtained data indicates the virucidal activity of the claimed coagulant against the three most stable pathogens - hepatitis A virus, rotaviruses and noraviruses.

In addition to assessing the virucidal properties of pathogens, in the SP SRI EM EM. PASTERA was commissioned by the Customer to study and determine the activity of a new titanium coagulant on a standard set of microbiological markers. Moreover, the assessment of disinfectant activity was carried out at maximum dilutions of the most indicative microorganisms; The results of the study gave positive results of the cleansing ability of the claimed coagulant.

Example 18

The study of a safe method of preparation and method of using the claimed titanium coagulant (lack of mutagenic effect; sensitizing, allergenic, oncogenic, gonadotoxic, etc.) was carried out on the basis of the A. N. N. State Institute of Human Ecology and Environmental Hygiene. Sysina of the Russian Academy of Medical Sciences (RAMS).

Based on the position that coagulants, as a rule, are a complex composition, methods for determining coagulants in water were mainly aimed at identifying the leading component. In particular, derivatives of aluminum oxychloride (OXA) and aluminum sulfate were controlled by the aluminum content in drinking water. In the study of the claimed coagulant, the same principles for assessing the safety of titanium coagulant were used as the safety assessment of coagulants based on aluminum. Studies (Table 21) showed that the introduction of titanium into the coagulant does not increase acute toxicity.
