Description

The present invention relates to a device intended for physico-chemical and bacteriological treatment of industrial wastewater or liquid waste.

Currently, in most cases, industrial wastewater is supplied to general water treatment plants for subsequent treatment and purification.

To do this, between industrial enterprises, discharge wastewater, and companies that provide treatment and purification of wastewater, the relevant agreements are concluded.

The cost of treating these industrial wastewaters may be too high for industrial enterprises and in some cases may exceed the cost of the raw water used by these enterprises.

Since the responsibility for the implementation of appropriate treatment of industrial wastewater, thus, remains with the industrial enterprises themselves, they may consider the option of installing their own means of treatment and purification of water used at these enterprises.

However, modern devices for the treatment and purification of industrial wastewater are not fully adapted to the treatment of this wastewater or liquid waste on the scale of a single enterprise, which discharges relatively small amounts of wastewater, comparable, for example, to those wastewater volumes usually discarded by a small administrative-territorial entity.

Indeed, these modern water treatment devices contain many elements that consistently carry out the operations of homogenizing wastewater, their degreasing, coagulation and flocculation. These devices are quite expensive and occupy a large area on the ground surface.

For these reasons, it may be difficult for a conventional industrial enterprise to provide its own installation of this type, designed to purify the liquid waste produced by this enterprise.

The present invention is to create a device intended for the treatment of industrial wastewater or liquid waste, which has a reduced overall dimensions and has an economically acceptable cost of acquisition and operation, while ensuring a high degree of purification of liquid waste.

The technical result is achieved by a device for cleaning industrial wastewater or liquid waste in accordance with the invention, comprising a tank for clarifying liquid waste, a pump pulverizing wastewater or liquid waste into a chamber located on the upper surface of the clarification tank, at least one the pump of the dosed supply to the chamber of the additive in the form of a chemical reagent that provides for the coagulation or flocculation of liquid waste, a vertical feed channel that supplies liquid s waste with introduced additives in them from the chamber to the bottom of the flocculation tank, located inside the clarification tank in which a layer of clay mass, through which the processed liquid waste is in the upward direction and in contact with which the liquid wastes are cleared.

Due to the introduction of treated liquid waste into the base of the layer of accumulated silt, the degree of aggregation of contaminating materials, organic or mineral, present in these liquid wastes, on the lumps that form the layer of silt, is maximum. In addition, the flow of liquid waste in the pulsating mode allows the clumps of these silt masses to be set in motion and thereby increase their ability to aggregate the contaminants contained in the liquid waste. Thus, this device allows to provide a very effective flocculation for a reduced period of time.

Accordingly, the consumption of chemical reagents used is reduced due to the maximum efficiency of the flocculation process.

The waste liquid purification device according to the invention allows for a reduction of ΌΒΟ by more than 70%, as well as an excellent filtration of the metals present in the liquid waste.

One of the main criteria for pollution of wastewater is the ΌΒΟ level, that is, the level of biological oxygen consumption, which is the level of oxygen consumption by microorganisms present in the wastewater to be treated, for these microorganisms to assimilate the organic matter contained in these wastewaters.

Preferably, the upper part of the flocculation tank is made in the shape of a truncated cone and continued with the lower cylindrical part into which the inlet channel opens.

Due to this particularly preferred configuration of the flocculation tank, the sewage into which chemical additives have already been introduced is fed into an area whose volume is relatively small, namely, into the cylindrical part of the flocculation tank. In this relatively small volume, the flocculation process is carried out especially intensively.

At the same time, due to the inclined surface of the conical part of this flocculation tank, the silt mass formed as a result of the accumulation of lumps of sludge can be removed outside the flocculation tank under the action of the increased pressure of the supplied liquid waste.

In this case, the flocculation process is carried out dynamically and is self-regulating. Indeed, at any pressure of supplying liquid waste to which this device is subjected, the flocculation process is always carried out in an optimal way, on the one hand, by ensuring intensive flocculation at the level of the cylindrical part, and on the other hand, by overflowing out of the tank flocculation of excess silt.

In accordance with a particularly preferred embodiment of the present invention, the feed channel comprises a first pipe, one end of which opens into the chamber, and its other end, provided with radial homogenization holes, is located above the surface of the conical tank, and a second pipe whose diameter exceeds the diameter of the first pipe, the upper end of the second pipe covers the circumferential homogenization holes made in the first pipe, and the second, lower end of it opens into the lower part of the conical tank.

The configuration of the feed channel ensures homogeneous mixing of liquid waste and added chemical reagents before introducing this mixture into the lower part of the flocculation tank.

Preferably, the lower part of the clarification tank has a conical part into which the silt masses are poured over the edge of the flocculation tank, and a special pump removes these silty masses, thus collected in this conical part, from the clarification tank.

Due to the conical shape of the lower part of the clarification tank, the silt mass that leaves the flocculation tank is collected on the surface bounded by the base of the clarification tank. These silt masses can easily be extracted from there with an appropriate pump. Thus, changes in the pressure of the flow of liquid waste can be provided without any particular difficulty, and the regulation of the layer of oozy masses is carried out in an autonomous manner.

Preferably, the calibrated holes are made at the top of the clarification tank in order to allow the clarified liquid waste to be poured into the storage tank, covering the clarification tank.

This storage tank covers the clarification tank located inside it, which makes it possible to obtain a particularly compact design of a water purification device, which occupies a definitely smaller area on the ground than similar devices according to the state of the art in this field.

Preferably, the lower end of the feed channel has a diverging conic section in order to improve the dispersion of liquid waste in the layer of sludge.

In accordance with a preferred form of implementation of the present invention, the filter material is located between the clarification tank and the storage tank, with the clarified liquid waste passing through this filter material before it accumulates in the lower part of this storage tank.

In accordance with a preferred embodiment of the present invention, the pumps providing the metered supply of the used chemical reagents, inject the necessary reagents, respectively, into the lower part of the mixing chamber, into the liquid waste supply channel before the static mixer and into the bottom zone of the cylindrical part of the flocculation tank. Thus, chemical reagents are introduced at the points at which they can perform optimal action.

In accordance with a preferred embodiment, the wastewater treatment apparatus comprises a filtration tank containing filtering material located between the chamber and the flocculation tank, a wall located between the flocculation tank and the filtration tank, a channel whose diameter exceeds the diameter of the supply channel and which is made coaxial with respect to feed channel, passing between the wall and the filtration tank.

Preferably, the upper edge of the conical part of the flocking tank is adjacent to the inner surface of the clarification tank.

Preferably, the filtration tank has openings on its lower surface, protected by mesh filters that allow filtered water to pass through.

The filtering mass provides a reduction in the content of residual impurities at the outlet of the clarification tank.

In accordance with a particularly preferred embodiment of the present invention, a special pump sucks up already clarified liquid waste from the storage tank and introduces it into at least one annular chamber located on the outer surface of the storage tank and containing fine-grained material that delays bacteriological elements.

Clarified liquid waste is driven in an annular chamber, which contains fine-grained material that delays bacteriological elements. In this case, the vortex flow, which is attached to the liquid waste in the annular chamber, provides a sufficiently effective contact between this fine-grained material and liquid waste, and as a result, provides a fairly quick and very effective retention of bacteria. At the same time, a decrease in the level of ΌΒΘ reaches 95% or more.

Preferably, four annular chambers are used, each of which chambers communicating with an annular chamber adjacent thereto via a corresponding channel.

Each of these annular chambers contains fine-grained material that has the ability to trap specific bacteria, while the sequential passage of liquid waste through four such chambers provides a very effective biological cleaning of the treated liquid waste.

Preferably, a special acceleration pump sucks the clarified liquid waste at the level of the upper annular chamber and supplies them to the lower annular chamber.

This accelerator pump maintains a uniform annular velocity of the liquid waste, in which the fine-grained material is in suspension.

Preferably, the storage tank, the clarification tank, the flocculation tank and the annular chambers are made of plastic material.

The present invention will be better understood from the following description of a preferred embodiment of a device for the treatment of wastewater or liquid waste, with reference to the accompanying drawings, in which FIG. 1 is a schematic sectional view of a device for wastewater treatment in accordance with the present invention;

in fig. 2 is a schematic view of a wastewater treatment apparatus in accordance with the present invention incorporated in an installation for treating this wastewater;

in fig. 3 is a schematic view of an embodiment of the present invention intended to prepare potable water in isolated locations.

FIG. 1 shows a schematic sectional view of the device; this device for cleaning industrial wastewater or liquid waste contains a cylindrical storage tank 1. In this case, a cylindrical clarification tank 2 is located in a concentric manner inside the reservoir 1. The clarification tank 2 contains round and evenly distributed calibrated holes in its upper part 3, and in its lower part has a conic section 4. These concentric tanks 1 and 2 are connected to each other by means of an annular platform 5, on which is put the filtering material 8. The annular platform 5 comprises uniformly distributed holes 6. Above each of these openings 6 is arranged a strainer 7.

The flocculation tank 12 is located inside the tank 2. The flocculation tank 12 is formed by an upper conical part 13, the cross section of which decreases in the downward direction and which is extended by the lower cylindrical part 14. The flocculation tank 12 is provided on its lower side with supporting structures 15, which in turn are supported by bottom part of the clarification tank 2.

The extraction channel 17 is opened between the supporting structures 15 of the flocculation tank 12, and the extraction of the substance therein is carried out by means of a pump 18.

The chamber 20 is located on the upper surface of the tank clarification 2. This chamber 20 is fed to be treated with liquid waste using a pump 21.

The feed channel 10 provides for the supply of liquid waste to be treated to the chamber 20, and the movement of these liquid waste is carried out by means of a pump 21.

This feed channel enters chamber 20 tangentially so that a stream of liquid waste is introduced into this chamber tangentially with an anti-vortex effect.

The static mixer 11 is located in the feed channel in front of the camera 20.

Pumps 22, 23, 24, intended for the dosed supply of appropriate chemical reagents, provide introduction of chemical reagents that promote flocculation or coagulation, respectively, into the lower part of chamber 20, directly into the supply channel 10, in front of the static mixer 11, and into the bottom zone of the cylindrical part of the flocculation tank 12 .

The vertical feed channel 25 passes from the chamber 20 to the beginning of the cylindrical part 14 of the flocculation tank 12. This feed channel 25 contains the first pipe 26 opening into the second pipe 27, the diameter of which exceeds the diameter of the first pipe 26. This pipe 26 opens at its upper end into the chamber 20, and its lower end is provided with radial holes 28. In this case, the hemispherical element 29 overlaps the lower end of this pipe 26. The pipe 27 covers the radial holes 28 made in the pipe 26, and continues until the beginning of the cylindrical part of the flocculation tank

12.

The storage tank 1 contains four annular chambers 31, 32, 33, 34 placed one on top of the other on its outer surface.

Each of these annular chambers communicates with the adjacent annular chamber using a corresponding channel 35.

In the design of this installation, a pump 36 is provided, which provides for the suction of fluid from the bottom of the tank 1 through the channel 37 and the injection of this medium into the lower annular chamber 31.

The acceleration pump 39 sucks fluid from the upper annular chamber 34 and pumps it into two intermediate annular chambers 32 and 33.

Air channel 38 provides for the introduction of compressed air into each of the annular chambers 31, 32, 33 and 34, as well as into each of the mesh filters 7.

The compressed air is introduced into the annular chambers by means of a compressor, which is not shown in the figures given in the appendix.

Each of the annular chambers is provided with a viewing window 41, which provides access to the interior of this annular chamber.

The upper annular chamber 34 extends to the top of the storage tank 1 and is provided with an opening 43 opening to the external environment.

The operation of the device described above is as follows: first of all, the liquid waste to be treated is subjected to a physicochemical treatment and then subjected to bacteriological treatment.

Liquid wastes coming from their storage area 45 are sucked by a pump 21, through which they are introduced into the chamber 20. A suitable chemical reagent is introduced into this liquid waste before a static mixer, which ensures very fast mixing of liquid waste with the introduced chemical reagent. Liquid waste is pumped in an intermittent manner by the pump 21, for example, suction takes place over a period of time ranging from 15 to 30 seconds, followed by a period of rest or stopping of the pump, having a duration of 15 to 60 seconds, so as to ensure the introduction of these liquid waste into chamber 20 in a pulsating manner. In the chamber 20, the pump 22 provides an introduction to the liquid waste of a special chemical reagent that promotes coagulation or flocculation. Chemical reagents can be, for example, ferric chloride, aluminum sulphate or polymers, and the choice of these chemicals depends on the type of liquid waste to be treated. The action of the pumps 22 and 23 corresponds to the period of pulsation in the process of feeding the treated liquid waste.

Under the action of the pulsations provided by the pump 21, the liquid waste with the corresponding chemical reagent already added to them is pushed out of the chamber 20 and into the vertical feed channel 25.

Holes 28, made in the upper pipe 26 of the feed channel, ensure the homogenization of the solution of the chemical reagent used in this case in liquid waste.

At the bottom of the feed channel 25, the treated liquid waste is brought into contact with a layer of silt, which forms lumps. These lumps of clay masses are in suspension as a result of pulsations provided by the movement of liquid waste. In contact with the oozy lumps forming a layer of the oozy mass, organic or mineral impurities are aggregated on the lumps, and as they pass through the layer of the oozy mass, liquid waste is cleaned. The introduction of a chemical reagent, providing flocculation, using a pump 24 allows to intensify the flocculation process.

In the case of increasing the pressure of supplying liquid waste, an excess amount of oozy masses overflows over the edge of the flocculation tank and accumulates in the central zone of the conical part 4 of the clarification tank 2. These excess oozy masses are removed from the bottom of this tank with the help of a pump 18.

Since the clarified liquid waste has a density lower than the density of lumps that form a clay mass, they are poured out of the clarification tank through the holes 3 made in it.

When this clarified liquid waste overflows into the lower part of the storage tank 1, which covers the tank clarification, while passing through the filter mass 8.

This filtering mass can be formed by grains of quartz, pozzolan, activated carbon, diatom algae or pieces of pumice and allows to reduce the residual pressure of liquid waste after clarification.

The filtering mass used in this case can be washed by introducing a mixture of water and air through the nozzles 9 in a countercurrent. This mixture of water and air is introduced simultaneously and in an equal volume with the extraction of excess sludge masses by means of a pump 18 in order not to disturbances in the dynamics of the process of clarification and cleaning.

At this point, liquid waste undergoes a physico-chemical treatment and is thus purified. They then accumulate at the bottom of the storage tank.

Thereafter, the liquid waste is sucked by the pump 36 and injected, after introducing air into the liquid, into the annular chamber in a tangential manner so as to create a vortex flow inside this chamber. The annular chamber 31 contains a fine-grained substance that traps bacteria present in the treated liquid waste. Inside this annular chamber, the fine-grained substance is suspended in a swirling flow of liquid waste. The stay of fine-grained substances in suspension and the constant mixing of this fine-grained substances provide excellent retention of bacteriological contaminants present in the liquid waste.

The pump 39 sucks the liquid waste in the direction of the annular chambers 32, 33 and 34, which communicate with each other through the appropriate channels 35. This pump maintains a constant velocity of liquid waste in the annular chambers, ensuring the reintroduction of this liquid waste sucked from the upper annular chamber 34, into the intermediate annular chambers 32 and 33. Each of these annular chambers 31, 32 and 33 contains a special fine-grained substance (activated carbon, sand or calibrated polystyrene balls) that exerts not to certain bacteria, so that in the case when these liquid wastes are removed from the annular chamber 34 through the opening 43, they are subjected to full bacteriological treatment.

Liquid waste may also be subjected to post-treatment, for example, as a result of the addition of a disinfectant, shown at 45 in FIG. 2

FIG. 3 schematically shows the form of implementation of the present invention, intended for the production of drinking water in isolated places.

In this embodiment, the implementation of the device in accordance with the present invention is supplied with contaminated water using a manual pump 50.

The tank 2 is divided into several parts using two horizontal partitions 51 and 52, which define the upper part 47 of this tank, its intermediate part 48 and its lower part 49.

The upper part of this tank contains a chamber 20, into which a feed channel 25 is opened by means of a hole made in the partition 52.

The feed channel 25 connects the chamber 20 with the flocculation tank 12, which is located at the bottom of the tank 2.

The lower end of the feed channel 25 has a diverging conic section 57.

The flocculation tank 12 rests on the bottom of the tank 2, and its conical upper part 13 adjoins the inner wall of this tank 2.

The conical part 13 of the flocculation tank contains holes 55 for pouring.

The partition 51 contains one round hole, to which is attached the removal channel 56, made concentric with respect to the feed channel 25.

The removal channel 56 contains radial pouring holes 59 at its upper end and ends in a filtration tank 60 filled with filter material, such as sand, for example.

Special channel 66 provides the ability to fill the tank 60 with the appropriate filter material.

The bottom part of the filtration tank 60 is provided with holes 61 protected by mesh filters 62.

Each such screen filter 62 is provided with a washing nozzle 65 associated with the pump 50.

Each of the parts of the tank 2, namely, the upper, intermediate and lower parts thereof, is equipped with an emptying valve, respectively, 61, 62 and 63.

Manual pump 50, due to the presence of a three-channel valve 67 with manual control, has the ability to suck up the fluid coming from the well 68 or from the intermediate part of the tank 2. Thanks to the use of the three-channel valve 68 with manual control, this pump has the ability to force the fluid into the upper part of the tank 2 or into the channel 70, which feeds the washing nozzles 65.

Further, the operation of this water treatment device in accordance with an embodiment of the device according to the present invention will be described in more detail.

The valves 67 and 68 are located in such a way as to ensure the absorption of unsuitable for drinking water from the well 68 and the injection of this water into the upper part of the tank 2.

The water thus extracted is subjected to settling and clarification, and the particles contained in it are deposited on the partition wall 52.

A chemical reagent providing flocculation or coagulation is introduced into the chamber 20 by means of a pump, which is not shown in the figures in the appendix.

After a sufficient amount of water is introduced into the upper part 47 of the tank 2, this water begins to overflow into the chamber 20, and then into the feed channel 25, which opens into the flocculation tank 12.

In the lower part of the feed channel 25, water is introduced into contact with a layer of silt, which is formed by lumps. The diverging conic section of the feed channel 25 provides excellent dispersion of water in the layer of this silt. Thus, the water is cleaned in contact with the fluidized layer of sludge.

Excessive silt masses are removed from the flocculation tank 12 through holes 55 and poured into the bottom of tank 2. These silty masses can be removed from there through valve 63.

Under the action of the pulsations created by the pump 50, the already purified or clarified water leaves the lower part 49 of the clarification tank through the removal channel 56 and is poured through the holes 59 into the filtration tank 60.

Since this filtration tank is filled with filtering material, such as sand, for example, already clarified water undergoes a filtration process. Water leaves the filtration tank 60 through the openings 61 protected by screen filters 62 and accumulates in the intermediate part 48.

The filtered water can be extracted from this intermediate part through valve 62 and can be used for use as pure water.

Water can also be subjected to a second cleaning cycle by arranging valves 67 and 68 so that the pump 50 sucks at the level of the intermediate part 48 water that has already been subjected to the first cleaning cycle and pumps this water to the level of the upper part 47 so that it is subjected to a new cleaning cycle.

In addition, valves 67 and 68 can be positioned in such a way as to ensure that this water is sucked at the level of the intermediate part 49 and injected it through the channel 70 into the washing nozzles 65. These washing nozzles 65 open into the mesh filters 62 and the water pumped in countercurrent, washes the filter medium. During this flushing operation, the valve 63 remains open.

Thus, the present invention proposes a particularly compact and sufficiently economical device for the treatment of industrial wastewater or liquid waste, which has excellent physical, chemical and bacteriological characteristics.

It should be noted that the present invention is not limited to those examples of its implementation, which were described above, but also covers all other possible options for its implementation. For example, a device for wastewater treatment or liquid waste can be made in the form of a module, including electronic devices for monitoring and controlling various pumps, and placed on a transportable platform.
