Description

Technical field

The utility model relates to the field of wastewater treatment, namely to filter cartridges for wastewater treatment, containing a housing that consists of a side cylindrical wall, an upper and lower water-permeable end and an outer solid flange in its upper part, the housing being filled with wastewater-purifying materials and has a tube extending between the upper and lower ends inside the housing.

State of the art

There are many designs of filter cartridges used for wastewater treatment (for example, No. 138499, B01D 27/02, published 03/20/2014; No. 139065, B01D 27/00, published 04/10/2014; No. 59996, B01D 27/00, published 10.01 .2007).

The disadvantage of these devices is the lack of design features that allow you to discharge untreated water accumulated above the filter cartridge without cleaning, if necessary (for example, when the territory is flooded).

Known designs of filter cartridges used for wastewater treatment, equipped with a pipe passing between the upper and lower water-permeable end inside the housing (for example, No. ; No. 149627, B01D 27/02, C02/F1/28, published 1/10/2015; No. 150862, B01D 27/02, published 02.27.2015; No. 166602, B01D 27/02, C02/F 1/00, E03F / 5/14, published 12/10/2016).

The disadvantage of these devices is the lack of design features that make it possible not to discharge untreated water above the filter cartridge without cleaning, when the filter cartridge is operating under conditions that do not require such a discharge.

The solution described in patent No. 166602 is the closest in terms of essential features to the claimed utility model and is taken as a prototype.

Utility Model Disclosure

The technical problem solved by the claimed utility model is the lack of opportunities for Russian consumers operating in the field of improving the environment and wastewater treatment to use a filter cartridge with an external solid flange around the perimeter of the housing, with a switchable bypass for emergency discharge of excess wastewater being treated. These consumers are forced to use filter cartridges for these purposes, either with a constant discharge of untreated water, or without the possibility of such a discharge, for example, those listed in the "Prior Art" section of this application.

In Russia, the practice of using filter cartridges for wastewater treatment from various pollutants is widespread. Many patents have been published (for example, patents from the "Prior Art" section of this application), as well as a number of articles (for example, Bobkov A.V., Bobkova O.A. Cleaning polluted storm drains on highway bridges // Roads and bridges. - 2010 - No. 24. - P. 231-247; Vatin N.I., Chechevichkin V.N. Features of the composition and treatment of surface runoff in large cities // Engineering and Construction Journal. - 2014. - No. 6. - P.67- 74; Vatin N.I., Chechevichkin V.N. Economic treatment of surface runoff in large cities. Filtration-sorption technologies // EuroStroyProfi. - 2015. - No. 78. - P.48-52; Vatin N.I., Grekov M.A., Leonov L.V., Probirsky M.D., Rublevskaya O.N., Chechevichkin A.V., Yakunin L.A. Results of test operation of the FOPS filter for cleaning storm water from the residential area of St. Petersburg / / Water supply and sanitary engineering. - 2017. - No. 1. - P. 58-65, Norman L.V., Vyskubova E.N. Treatment of surface wastewater // Scientific works of KubGTU. - No. 2. - 2016. - pp. 1-11). In the vast majority of references to filter cartridges for wastewater treatment from various pollutants, it is noted that, firstly, the filter cartridge has a solid flange, and secondly, the filter cartridge is located on a support ring inside the sewer well between its wall rings, in other words , this design is inherent in most of the filter cartridges used and can be taken as standard in Russia. According to the law "On Standardization in the Russian Federation" (Federal Law of June 29, 2015 No. 162-FZ "On Standardization in the Russian Federation", current), the goal of standardization in Russia is "optimization and unification of the product range, ensuring its compatibility and interchangeability, reducing the time of its creation, development in production, as well as the cost of operation and disposal. Therefore, when developing and introducing new types of filter cartridges for wastewater treatment from various pollutants, it is necessary to be guided by the principles of standardization and ensure the compatibility and interchangeability of previously produced filter cartridges and newly developed ones. To do this, it is necessary to ensure that the newly developed filter cartridges have such essential features as a housing having a side cylindrical wall, upper and lower water-permeable ends, as well as the presence in the upper part of the housing of an external solid flange along the perimeter of the housing.

The objective of the claimed utility model is to develop a simple, cheap and reliable design of a filter cartridge with an external solid flange around the perimeter of the housing, which makes it possible to manually turn on and off the discharge of excess wastewater being treated without treatment.

In accordance with the Water Code of the Russian Federation, the main task of the nature user is to minimize the harmful impact on water bodies, and filter cartridges are used as treatment facilities to minimize such impact. In this regard, the discharge of untreated effluent is not completely prohibited, but its amount should be minimized. Filter cartridges with a constantly open pipe do not contribute to solving this problem, as they constantly dump untreated waste. But the operation of filter cartridges without the ability to discharge runoff without cleaning is difficult at all, since the filter cartridge will eventually become completely clogged, and the well with it will overflow with water, which will lead not only to flooding of the territory, but also to uncontrolled discharge of runoff without treatment at all, in bypassing sewer networks, which is unacceptable.

The technical result of the utility model is to increase the efficiency of water purification by a filter cartridge for wastewater treatment, containing a housing that consists of a side cylindrical wall, upper and lower water-permeable ends, and an outer solid flange in the upper part of the housing, the housing being filled with wastewater-purifying materials and has a tube extending between the upper and lower ends inside the housing, other things being equal.

Hereinafter, under "water purification efficiency of a filter cartridge for wastewater treatment, containing a housing that consists of a side cylindrical wall, upper and lower water-permeable ends, and an external solid flange in the upper part of the housing, the housing is filled with wastewater purifying materials and has a pipe , passing between the upper and lower ends inside the housing, all other things being equal, "means the total amount of pollutants that ended up in the treated effluent after it passed through a filter cartridge with a standard cleaning load, of a standard height and diameter, when it received a effluent with a standard capacity , with a standard amount of pollutants in it over one long period of time, covering both periods of low sewage supply (dry time) and extremely high water supply (heavy rainfall).

The claimed technical result is achieved in that the filter cartridge for wastewater treatment, containing a housing that consists of a side cylindrical wall, upper and lower water-permeable ends, and an outer solid flange in the upper part of the housing, the housing being filled with wastewater-purifying materials and having a pipe, located between the upper and lower ends inside the housing and equipped with a plug.

Brief description of the drawings

For a better understanding of the essence of the utility model, its description is considered with the involvement of the accompanying drawings.

The proposed drawing illustrates only one preferred embodiment of the utility model, and therefore cannot be considered as limiting the content of the utility model, which does not include other options for its execution.

Implementation of the utility model

In FIG. 1 shows a schematic representation of the inventive filter cartridge installed in a reinforced concrete storm water well for cleaning runoff in a storm sewer network, where the following are indicated: 1 - side cylindrical wall of the filter cartridge; 2 - upper permeable end; 3 - lower permeable end; 4 - outer solid flange; 5 - wastewater treatment materials; 6 - pipe; 7 - plug; 8 - untreated water; 9 - purified water; 10 - reinforced concrete well; 11 - support ring.

The filter cartridge is installed using a solid flange 4 inside the reinforced concrete sewer well 10 on the support ring 11. Untreated water 8 enters the filter cartridge from above and then exits from the bottom, either already cleaned, having passed through the cleaning materials 5, or not purified (if necessary ) passing through the pipe 6. The plug 7 covers the section of the pipe 6, thereby preventing water from passing through the pipe 6.

The attribute of the utility model "the pipe is equipped with a plug", inherent in the distinctive part of the formula of this utility model, is an essential feature and a necessary condition for achieving a technical result within the scope of the claimed filter cartridge, since:

According to the dictionary of Efremova (Efremova Tatyana Fedorovna. New Dictionary of the Russian Language. Explanatory and derivational: [In 2 volumes] - M .: Rus.yaz., 2000. - T. 2: P - I. -1084 s): stub - This is a device for closing the hole tightly.

According to the technical railway dictionary (Technical Railway Dictionary N.N. Vasiliev, O.N. Isaakyan, N.O. Roginsky, Ya.B. Smolyansky, V.A. Sokovich, T.S. Khachaturov - M .: State Railway Transport publishing house, 1941 - 608 pp.): a plug is a general name for a part that serves to temporarily or permanently tightly cover a hole.

In other words, a “plug” is an arbitrary device that allows you to open and close a pipe section (hole) at the operator’s discretion, thereby allowing untreated drain to pass through it or not.

Due to the fact that the compared filter cartridges without a plug and with a plug are otherwise identical (standard cleaning load, standard height and diameter, standard capacity, with a standard amount of pollutants in it), the total amount of pollutants that ended up in the treated effluent after it has passed through the filter cartridge will depend only on how much untreated waste has passed through the pipe.

According to the articles previously mentioned in the "Disclosure of the utility model" section, the period of operation of a filter cartridge commonly used in Russia is at least one year, that is, it affects both dry (summer) and rainy (spring, autumn) periods of its operation. During these periods, the total amount of untreated water entering the filter cartridge, as well as the intensity of its supply, differ greatly. Moreover, even during the rainy period there are periods of low intensity of rain and high intensity (intense downpours). In this regard, the operation of the filter cartridge both without a pipe at all and with a constantly open pipe is not rational, since it will either lead to flooding (without a pipe at all) or to frequent discharge of untreated drain (permanently open pipe).

This problem is solved by installing a plug on the pipe, which can be opened or closed by the operator at the right time. For example, it is always closed in summer and periodically open in autumn and spring.

Thus, the inventive filter cartridge has the advantages of both a filter cartridge without a pipe and a filter cartridge with a permanently open pipe, but does not have the disadvantages of both.

The total amount of pollutants found in the treated effluent after it passes through the inventive filter cartridge will be less than they would have passed through the filter cartridge with a permanently open pipe (prototype), by the amount that would have passed during the time that the inventive filter cartridge worked with a closed plug, which is the achievement of the claimed technical result.

Features of private forms of implementation of the filter cartridge in terms of the material from which the filter cartridge is made do not affect the achievement of the technical result, which is provided in any of the cases inherent in this degree of generalization of the feature, since:

If the filter cartridge is originally intended for wastewater treatment, according to the claimed technical field, then by definition it can always be used for wastewater treatment. Within the limits of the material from which the filter cartridge is made, this material cannot affect the ability of the filter cartridge to clean the runoff passing through it.

This generalized feature can be implemented in a material carrier, for example, in the variant: plastic of any kind, steel, composite material.

Features of private forms of implementation of the filter cartridge in terms of the type of wastewater-purifying materials or their quantity do not affect the achievement of the technical result, which is provided in any of the cases inherent in this degree of generalization of the feature, since:

If the filter cartridge is originally intended for wastewater treatment, according to the claimed technical field, then by definition it can always be used for wastewater treatment. In terms of the type of wastewater treatment material or its amount, this material cannot affect the ability of the filter cartridge to clean the effluent passing through it. If the material in the filter cartridge does not provide wastewater treatment, then the entire filter cartridge as a whole will not be designed for wastewater treatment, therefore, it cannot be attributed to the field of technology of this application.

This generalized feature can be implemented in a material carrier, for example, in the variant: non-woven filter material, fabric, synthetic winterizer, lavsan, activated carbon, charcoal, modified carbon, zeolite, vermiculite. In addition, the filter cartridge can be completely or partially filled with water-purifying materials. In addition, the filter cartridge may be filled with one or more water purification materials.

Features of private forms of implementation of the filter cartridge in terms of the type of water permeability of the ends do not affect the achievement of the technical result, which is provided in any of the cases inherent in this degree of generalization of the feature, since:

Openings of any shape and size will allow untreated runoff to reach and exit the water purifying materials, thereby achieving a technical result.

The variability of water permeability can be implemented in a variation in the shape and size of the holes. In a material carrier, it can be implemented, for example, in the form of a lattice, mesh or membrane. The difference between them is only in the shape and size of the holes, which can be anything.

Features of private forms of implementation of the filter cartridge in terms of the diameter of the pipe with a plug do not affect the achievement of the technical result, which is provided in any of the cases inherent in this degree of generalization of the feature, since:

A pipe of any diameter inside the body, directly connecting the upper and lower water-permeable ends, will ensure that the untreated drain flows through the filter without treatment.

Due to the fact that the plug (as a generalized device) blocks pipes of any diameter, the proportion of the drain that does not pass through the pipe due to the plug will not change, only its volume will change. Consequently, the efficiency of water treatment will still increase, just to a lesser extent, proportional to the ratio of the flow rate through the pipe and through the wastewater filtering material.

Features of private forms of implementation of the filter cartridge in terms of the type of material and the shape of the plug do not affect the achievement of the technical result, which is provided in any of the cases inherent in this degree of generalization of the feature, since:

According to the dictionary definitions given earlier, a “plug” is a generalized concept that indicates a device that is capable of shutting off a pipe.

Therefore, in order for the plug to achieve a technical result, it must be a plug (have design features that allow it to block the pipe section) and be made of a material that allows it to block the pipe. If the intended "plug" is not made of a material capable of blocking the pipe, then it will no longer be a "plug" by definition.

In the material carrier, the variability of the material from which the plug is made can be implemented, for example, in the form of steel, brass, plastic, wood, composite material, ceramics.

In the material carrier, the variability of the shape of the plug can be implemented, for example, in the form of a tap, plug, cap, film, membrane, valve, manual or automatic valve, plate.

Features of private forms of implementation of the filter cartridge in terms of the location of the plug relative to the pipe do not affect the achievement of the technical result, which is provided in any of the cases inherent in this degree of generalization of the feature, since:

The plug will not allow water to pass through the pipe, no matter where in the pipe the plug is located, according to its definition.

In the material carrier, the variability of the location of the plug in the pipe can be implemented, for example, in the form: in the middle part of the pipe, in the upper part of the pipe, in the lower part of the pipe, at the upper permeable end, at the lower permeable end.

The inventive filter cartridge will find wide application in Russia, since the need to treat storm water with the rational use of filter cartridges and minimize the discharge of untreated waste is now becoming an important and economically viable task not only for business entities, but also for water supply and sewerage organizations in cities .
