Description

Apparatus for purifying food-waste water and purifying system using it}

The present invention relates to a food sewage treatment apparatus for purifying and discharging domestic sewage including food waste and a comprehensive sewage treatment apparatus including the same.

Normally, the sewage contains a large amount of organic compounds. For example, household sewage discharged mainly from homes or restaurants includes food waste contained in dishes that are thrown out of the sink.

As such, when the sewage containing a large amount of organic compounds is waterproofed in a river or the like, the biochemical oxygen demand in the water is increased, which causes the river to significantly reduce its self-cleaning ability.

Looking at the sink of the home, the drain of the sink is provided with a drain trap so that the food is not drained into the drain pipe. Such drain traps are generally woven with a sieve having a certain size to separate food wastes, and have a large size for smooth drainage.

Therefore, a small volume of food waste, such as red pepper powder or rice grains, is discharged as it passes through the strainer, and thus, small food waste contained in the sewage is slowly decomposed, causing further deterioration of water quality.

Conventional techniques that have attempted to solve this problem have been concentrated on large facility equipment for application to sewage treatment plants where sewage is collected and purified. Therefore, it does not suggest effective measures for living sewage that are not collected in sewage treatment plants and discarded in nearby rivers, rivers, etc., and has limitations that do not solve various problems in which corruption occurs during transport to sewage treatment plants.

Hereinafter, the structure, function and operation of the food wastewater treatment apparatus and the comprehensive wastewater treatment apparatus using the same will be described. However, the same reference numerals for similar or identical components are used throughout the embodiments.

In addition, terms such as first and second may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component.

Food wastewater treatment apparatus according to the present invention is to be installed in the place where the waste water containing food is drained. Larger chunks of food waste contained in the sewage may be first filtered by a sieve provided separately or a solid matter separating and discharging device described below. The residual food waste of the sewage, which has passed through the filter net, is moved together with the sewage, and the food waste treatment apparatus according to the present invention is to filter the residual food waste to lower the content of food waste in the final discharged water.

Food wastewater treatment apparatus according to the present invention comprises a housing having an inner space, and a component installed inside. The housing is airtight and sewage is injected from one side and discharged from the other side. As a result, the internal space of the housing becomes a flow path through which wastewater passes, and a single flow path is formed by a component provided therein, or a plurality of partitioned flow paths are formed. The flow path formed inside the housing may have a zigzag shape by the component. This zigzag flow path increases the time for sewage in the limited space inside the housing and also increases the time for filtration.

In addition, the food wastewater treatment apparatus 10 according to the present invention has a flow path that forms a flow path therein, and filters the organic foreign substances such as residual food waste contained in the wastewater passing through the flow path to be filtered by adsorption, decomposition by microorganisms, and the like. It includes. Such filtrates include diatomaceous earth, activated carbon, acorns, minerals that release anions, calcium chloride, magnesium, and odor removers. Further, the filtrate may be any one of the group consisting of a combination of these.

Aconic acid contained in acorns is known to have a function of absorbing and releasing heavy metals and various harmful substances and having a heavy metal purification effect.

On the other hand, diatomaceous earth is a fossilized material after phytoplankton is deposited on the sea floor or lake bottom, and it is known to have excellent moisture control ability due to its ultra-porous structure with nanometer pores, and also has various deodorization and fire resistance properties. It is used as a filter medium, a degreaser, an absorbent, etc. Diatomaceous earth is also known to be harmless to the human body.

Activated carbon is a porous carbon agglomerate that is known to easily adsorb and remove moisture and odor components. In addition, it shows an excellent effect on the accuracy of contaminated air and water, and has the effect of slowing the progress of decay by preventing the occurrence of microorganisms and mold. It also has the property of adsorbing cations by releasing anions and decomposing harmful substances of sewage and purifying them. In addition, it is known to diverge water molecules by emitting far infrared rays to increase the amount of oxygen and to alkalinize water.

Anions are important for neutralizing cationic substances present in water, and are known to purify harmful compounds with cations such as formaldehyde and dioxins, for example. Minerals that emit negative ions are typically tourmaline and mordenite.

Calcium chloride is known for its cleansing properties, and magnesium is a nutrient that is supplied to microorganisms that break down organic matter. In addition, various well-known filtrates may be used.

As the sewage passes through the flow path, small food masses contained in the sewage pass through the filtrate, and are subjected to physical, chemical, and biological filtration, and the filtered sewage is discharged to the drain. Therefore, the sewage can be purified first before being sent to the sewage treatment plant, and even if the sewage is not collected into the sewage treatment plant and is discarded as it is in the surrounding rivers and rivers, it is possible to reduce environmental pollution such as eutrophication of the river or the river. In addition, it is possible to minimize the corruption of the sewage due to food waste remaining in the sewage during the process to the sewage treatment plant.

On the other hand, the comprehensive sewage treatment apparatus is installed in a kitchen or a restaurant, etc., to effectively separate and remove food waste from the discharged sewage. The comprehensive sewage treatment device includes a pulverizing device for dividing the food mass contained in the sewage.

Furthermore, the food mass divided into pieces is again classified according to the volume, so that the large volume mass is separated and moved to the solid separation and discharging apparatus, and dried and discharged as a solid. Small volumes that could not be separated in the solids separating and discharging device move with the sewage and are filtered out in the food wastewater treatment system.

Further, in order to safely protect the user from the grinding apparatus, a drain cover is further provided on the upper part of the grinding apparatus, and the grinding apparatus is configured to be operable only when the drain cover covers the drain port. This allows the user to put a finger or other object into the drain during operation of the grinder to prevent possible fatal accidents.

Hereinafter, the food wastewater treatment apparatus and the comprehensive wastewater treatment apparatus according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 schematically show a food wastewater treatment apparatus 10 according to a first embodiment of the present invention.

The food wastewater treatment apparatus 10 according to the first embodiment of the present invention includes a housing 1, a partition 2, and a boundary 3.

First, the housing 1 has a space formed therein and is approximately in the shape of a hexahedron box. However, the shape of the housing is not limited to those shown in the drawings and may be variously changed. The top of the box is open, and the open top can be hermetically closed with a lid 13.

Here, a packing (not shown) is further provided between the lid and the top of the box to prevent leakage of sewage, and the lid is detachably coupled to the box by various temporary fixing means. For example, the temporary fixing means, as shown, a plurality of flaps 131 are provided along the outer edge of the lid 13, and the engaging piece (1a) protruding to correspond to the flap from the upper end side of the circumferential surface of the box May be). Such temporary fixing means can be variously modified, such as a tape clamp or belt.

An inlet 11 through which the sewage flows is formed on one surface of the housing 1, and an outlet 12 through which the sewage passing through the housing is discharged to the outside is formed. Pipes extend from each inlet and outlet, which may be flexible pipes, although not shown. In addition, although not shown, the inlet side may be further connected to the pipe for injecting air. This air is supplied from a separate blower device.

In the first embodiment of the invention the inlet 11 may be located higher than the outlet 12. In the first embodiment, the flow of sewage is in the direction of gravity, and the inlet 11 is formed higher than the outlet 12 so that a natural flow of sewage is generated inside the housing, and all of the sewage inside the housing is discharged to the outside of the housing. It is possible. This prevents stagnant sewage in the housing, thereby preventing corruption due to stagnant sewage.

On the other hand, the partition wall portion 2 includes a structure provided with an internal space of the housing 1 to form a first flow path through which the introduced sewage is sequentially filtered and the filtrate provided on the first flow path.

In other words, the partition wall portion 2 includes structures that block or direct the flow of sewage according to the direction from the inlet to the outlet, and induces a variety of complex shapes in which the sewage is not straight from the inlet to the outlet. To flow along the first flow path.

These constructs are presented as blocks to block the flow of sewage, formed into walls, or holes in the walls that lead to the flow of sewage.

Specifically, in FIG. 2, the partition walls 2 are erected apart from each other so as to cross the direction from the inlet to the outlet, and a plurality of partitions 21 having holes 211 through which sewage passes. It includes.

The partitions 21 are sequentially called the first partition 21a, the second partition 21b, the third partition 21c, and the fourth partition 21d according to the direction from the entrance to the exit.

As shown in the figure, each partition wall 21 is a plate member which stands on the floor inside a housing, and both ends extend to the inner wall surface of the housing 1.

In addition, a hole 211 through which filthy water passes is formed at one side or the other side of the bottom of each partition wall 21. In particular, the hole of one of the partition walls is formed in the opposite side to the neighboring partition wall, the first partition 21a and the third partition wall (21c) is the same as the hole formed on one side edge, the second partition wall 21b ) And the fourth partition 21d are formed with holes 211 at the other edge. As a result, as shown in FIG. 4, a first flow path (solid arrow direction) is formed in which the introduced sewage flows through each partition wall in a zigzag order.

In this case, the holes 211 of each partition wall 21 may be formed to have a plurality of densities as shown, or may form a single open space by increasing the diameter. When a plurality of holes are formed, it is possible to filter the food mass, thereby limiting the size of the food mass contained in the sewage that is moved to the rear side of the first flow path. This is important for maintaining or increasing the purifying effect depending on the filtrate described below.

In addition, by gradually decreasing the size of the hole 211 from the first partition 21a to the fourth partition 21d, the food mass contained in the sewage can be sequentially filtered. As described above, the small food masses are filtered out sequentially while passing through each partition wall, thereby reducing the blockage of the pores, thereby making it possible to reduce the size of the food mass contained in the final sewage very little. That is, the filtering function is improved while reducing the risk of clogging.

On the other hand, if formed in one hole is a major to smoothly flow the sewage.

In addition, the hole 211 of the partition 21 is formed near the bottom of the partition. This is important to allow the sewage to pass through the filtrate while preventing the sewage from accumulating inside the first channel.

If the filtrate is embedded in the mesh, the maximum height of the filtrate is usually lower than the height of the bulkhead. If the hole is formed at the top of the partition, there is a risk of passing through the hole formed at the top of the partition without passing through the filtrate. As a result, holes are formed in the bottom of the partition to allow sewage to pass through the filtrate where possible, thereby increasing the filtration efficiency.

On the other hand, the spacing of the partition wall may be different from each other. According to the permeability of the filtrate, a flow path having a low permeability filtrate is formed wide to allow the sewage to pass smoothly, and a flow path having a relatively permeable filtrate is narrowly formed, so that the flow of sewage It is possible to use the internal space of the housing having a limited area while smoothly.

On the other hand, the filtrate is provided in the space between the partitions. Each filtrate consists of one selected from the group consisting of diatomaceous earth, activated carbon, acorns, minerals emitting anions, calcium chloride, magnesium, deodorants and combinations thereof. In addition, the filtrate may be different from each other in the space partitioned by the partition.

For example, in FIG. 4, three spaces in which the filtrate is provided are formed in the first flow path by the first partition 21a to the fourth partition 21d, and at least one filtrate 22 is formed in each space. It is provided.

At this time, for example, the filtrate entering the space between the first partition 21a and the second partition 21b is diatomaceous earth, and the filtrate in the space between the second partition 21b and the third partition 21c is an acorn. The filtrate in the space between the third and fourth partitions 21c and 21d is activated carbon. The type of such filtrate may vary.

Here, diatomaceous earth or crushed acorns can be contained in fine mesh and put between partition walls. As a result, diatomaceous earth or pulverized acorns can be prevented from being easily swept away with the sewage, and the diatomaceous earth, which has expired life, can be separated and discharged without covering the housing, thereby easily replacing the filtrate.

Filtrate made of diatomaceous earth can be settled by microorganisms for biological filtration of organic matter. In addition, since the organic matter mass is filtered in the pores of diatomaceous earth, the physical filtration treatment can be performed in parallel. In addition, the anion activated by diatomaceous earth can attract and neutralize the cationized compounds passing through the surroundings.

On the other hand, the acorns provided between the second bulkhead and the third bulkhead filter the food waste remaining in the sewage that has passed through the diatomaceous earth, and the activated carbon provided between the third partition and the fourth bulkhead is the odor component or residue of the sewage. To purify sewage.

On the other hand, the height of the partition wall 21 is lower than the vertical height of the space inside the housing 1. That is, the overall height of the partition wall part 2 is formed lower than the height of the whole housing 1. The space formed in the upper part of the partition part 2 and the boundary part 3 which partitions the partition part 2 are provided.

In detail, the boundary part 3 is detachably coupled to the upper part of the partition wall part 2 and borders the first flow path and the second flow path through which the sewage overflowing the partition wall part 2 passes.

In FIGS. 2 and 3 the boundary part 3 is shown as a plate member covering the top of the partition wall part 2.

The boundary part 3 can be detachably fixed to the upper part of the partition part 2. One of the means for fixing the boundary part is to protrude the fixing step 1b which the boundary part bites on the inner side of the housing. Another means is to have a member that extends above the boundary to press the boundary when the lid is closed.

The fixing step or the member for pressing the boundary may be used together, but various configurations for detachably fixing the boundary at the upper part of the partition wall may be applied.

The second flow passage partitioned from the first flow passage inside the partition wall portion 2 by the boundary portion 3 is formed to open in a direction from the inlet 11 to the outlet 12 of the housing 1 so that the sewage is quickly discharged. do. That is, there is no structure on the second flow path that is resistant to the flow of sewage or is minimized.

In addition, the boundary part 3 covers the open upper space of the partition part 2 and prevents the filtrate, which is swept away by the flow of sewage from the partition wall part 2 even if the specific gravity is small or the specific gravity is large.

Since there is a flow resistance by the partitions constituting the partition 2 and the filtrate 22, when filthy water enters at once, the drainage is not made smoothly. When the kitchen sink is viewed as an inflow source of wastewater, a large amount of wastewater flows in many cases where the amount of food waste is low, such as washing food materials. This large amount of wastewater bypasses the bulkhead to allow the second channel to be discharged quickly to the exit.

In FIG. 3, the main flow of sewage when a large amount of sewage flows at one time is indicated by a white block arrow. In the initial stage when a large amount of sewage enters the interior of the housing 1, the sewage collects between the inner wall of the housing 1 in which the inlet 11 is formed and the first partition 21 a. At this time, a part of the sewage is introduced into the partition wall part 2 through the hole of the first partition wall 21a, and then flows along the first flow path. In FIG. 3, the flow of sewage through the first channel is indicated by a solid arrow or a dotted arrow. Here, the wire arrows indicate the direction in which the sewage passes through the hole formed on the other side of the partition wall.

On the other hand, as a large amount of sewage enters the interior of the housing 1, the water level of the sewage exceeds the partition 2 and eventually flows along the second flow path formed in the upper part of the partition 2 to the outlet.

Since the flow resistance of the second flow path is lower than that of the first flow path formed in the partition wall part 2, most of the large amount of sewage flowed into the outlet flows quickly through the second flow path. Thus, even if the inflow of sewage is variable has the advantage that the smooth drainage of sewage is guaranteed.

In addition, although not necessarily required, a plurality of passage holes 31 are further formed in the boundary portion 3. Passing holes 31 are arranged in a plurality of intervals on the plate forming the boundary (3). The passage hole 31 allows the wastewater passing through the second passage to flow into the first passage formed in the partition wall 2. In FIG. 3, the flow direction flowing into the first channel from the second channel is indicated by a black block arrow. In the initial stage when a large amount of sewage flows into the interior of the housing and in a boil in which the sewage level in the housing falls, the filtration treatment is induced by allowing the sewage to flow into the first flow path provided with the filtrate.

On the other hand, the boundary part 3 is provided with the inclined surface 32 which inclined downward toward the inlet 11 of the housing 1. The height of the first partition 21a is lower than that of the other partitions so that the boundary portion 3 can be installed.

The inclined surface 32 is important for the smooth flow of sewage toward the second flow path. That is, the sewage introduced in large quantities at one time is to easily cross the first partition of low height and to quickly cross the second flow path along the inclined surface 32.

In addition, if the through hole 31 is further formed on the inclined surface 32, the sewage having the water level higher than the first partition wall 21a is formed in the bottom of the first partition wall 21a and the through hole of the inclined surface 32. It is possible to quickly flow into the partition wall portion 2 by the (31). Thus, large amounts of sewage are introduced into the sequesters quickly and pass through the sequesters with possible filtrate.

In this way, the sewage introduced into the housing by the passage hole and the inclined surface formed in the boundary portion is guided to pass through the first flow passage provided with the possible filtrate, so that the filtration of sewage is performed as much as possible.

In addition, as shown in FIG. 2, a laminar flow plate 33 parallel to the direction from the inlet toward the outlet may be formed on the upper surface of the boundary part 3.

These laminar flow plates 33 are erected on the upper surface of the boundary portion 3, and in the case where a plurality of laminar flow plates are provided, they are spaced apart from each other in parallel. In FIG. 2, a total of three laminar flow plates 33, one at each end and the center of the boundary part 3, are arranged in parallel with each other.

The laminar flow plate 33 is parallel to the flow direction of the sewage passing through the second flow path, thereby helping the sewage flow out quickly without causing vortex inside the housing.

In addition, the upper end height of the laminar flow plate 33 reaches the upper end of the housing 1 when the boundary part is settled on the partition wall part. Therefore, when the lid 13 is covered with the housing 1, the upper end of the laminar flow plate 33 is in contact with the lid 13, and the laminar flow plate 33 presses the boundary 3. In this case, the boundary portion may be fixed to the upper portion of the partition wall even when a separate fixing means for fixing the partition wall is not provided.

On the other hand, the food wastewater treatment apparatus according to the second embodiment of the present invention is a processing space portion that flows through the introduced sewage and the water level control space portion to lower the level of the sewage overflowed from the processing space portion into another processing space portion The purification module provided is connected in plurality, and the sewage is discharged after passing through the plurality of purification modules in sequence.

Here, the purification module is a unit purifying means for filtering the food waste contained therein while passing the sewage, lowering the water level of the removed sewage filtration is discharged.

As shown, a plurality of purification modules are provided in the inner space of the housing which can be sealed with a lid, and the sewage flowing into the inlet of the housing is filtered through a plurality of times while passing through the plurality of purification modules, and then discharged to the outlet. do. The number of purification modules provided in the housing may vary depending on the design.

The purification module includes a treatment space part, a filter part, and a water level control space part.

Sewage flows in at a low height close to the bottom of the processing space, and the sewage gradually fills the processing space, so that the sewage in the processing space forms an upward flow from the bottom surface.

Further, in the processing space portion, when the sewage rises above a certain level, the overflow portion is formed so that the sewage flows into the water level adjusting space portion. The overflow portion may be formed of a overflow groove, a hole, or the like so that a part of the side walls of the processing space portion is formed at a low height or has a low height. Therefore, the introduced sewage gradually rises while filling the processing space part, and is discharged through the overflow part and falls into the water level control space part.

During this process, food waste, which has a high specific gravity or a large volume, has low liquidity and is deposited in the processing space.

On the other hand, the filtering part is a plate member which filters food waste while the wastewater passes. The manure part is provided inside the processing space so that the sewage passes as the sewage flows up.

Specifically, the manure part may be spaced apart from the bottom of the treatment space so that the rising sewage may pass, and may be formed of a manure plate having a plurality of through holes through which the food waste mass is caught. That is, the filtering plate is formed of a plate formed with a through hole of a constant size so that the rising sewage passes, and filters out the food waste mass larger than the area of the through hole among the food waste masses included in the sewage introduced into the lower portion of the filtering plate. This filtered food waste can be collected later by the user to maintain continuous manure performance.

In addition, since the manure is installed at the middle height of the treatment space, the sewage introduced from the bottom portion of the treatment space does not mainly pass through a portion of the manure close to the inlet but instead passes the whole manure at a relatively uniform flow rate. . Therefore, it is possible to filter the waste of food waste from the entire area of the filter part, thereby improving physical filtration performance.

In addition, although not shown in detail, in order to install the manure portion in the middle of the treatment space, the coupling portion having a coupling groove on the bottom surface of the treatment space portion is established, corresponding to the coupling fitted to the coupling groove on the back of the filter plate Protrusions may be provided.

In addition, the support plate may be further provided on the inner wall of the treatment space part in accordance with the installation height of the filter part so that the manure part is more stably combined.

In addition, the manure portion may be converted to a manure means such as various sponges for filtering food waste mass while passing the sewage in addition to the manure plate.

The filtrate may be contained in the processing space. Such filtrate may be contained in a fine mesh as described above, or may be introduced at the bottom of the manure. When the filtrate is provided in the lower part of the manure, even if the sewage rises, it is blocked by the manure and prevented from moving to another water level control space or another treatment space. Furthermore, the water level adjusting part may be provided with a filtering part or a filtrate having the same configuration as in the processing space part.

On the other hand, the water level control space portion lowers the water level of the sewage flowed into the processing space portion of the other purification module beyond the overflow portion in the processing space portion. To this end, the water level control space portion is provided with a circulation portion communicating with the bottom portion of the processing space portion of the neighboring purification module. That is, the height of the distribution portion is formed as low as possible so that sewage flows in from the bottom portion of the new processing space portion. Therefore, the sewage falling through the overflow portion into the water level control space can be introduced from the bottom of the new processing space through the low height distribution provided in the water level control space.

5 to 8, in the food wastewater treatment apparatus 10 according to the second embodiment, two purification modules are connected in sequence, and the last purification module is provided with a processing space part again. Hereinafter, for convenience of description, the first purification module is referred to as the first purification module 2A and the second purification module is referred to as the second purification module 2B based on the inlet. The same also applies to the internal components of each purification module. In addition, the processing space portion provided on the outlet side of the second purification module is referred to as the third processing space portion 29.

Under the condition that a plurality of purification modules should be provided in the inner space of the limited housing 1, in addition to each purification module, a third treatment space portion 29 is added before the final discharge of the wastewater. It can be done more times.

The housing 1 may be made of a substantially hexahedron, and a purification module having the above-described processing space portion and the water level control space portion is formed through sidewalls that divide the internal space. The inlet 11 of sewage formed at one side of the housing 1 is formed to be low so as to flow with the bottom portion of the first processing space 23.

The sewage flowing into the first treatment space 23 is gradually filled up in the first treatment space 23 and passes through the first manure 25, and thus the first wastewater 25 is formed in the first manure 25. The food waste mass larger than the first through hole 251 is collected in the lower portion of the first manure portion 25. Sewage that has passed through the first manure 25 is moved to the first water level control space 24 through the first moon current portion 231.

In the first water level control space 24, as shown in Figure 7, the first flow portion 241 is formed at a low height of the bottom portion. Therefore, the sewage that has passed over the first overflow portion 231 passes through the first flow portion 241 and flows into the bottom portion of the second processing space portion 26.

In this case, a simple wall 232 may be further provided between the first monthly flow part 231 and the first distribution part 241 to prevent reverse flow. The simple wall 232 separates the first space 233 in which the first filtered wastewater from the first processing space part 23 stays, and the second space 234 flowing through the second processing space part 26. It is partitioned. The first space 233 has a function of a damper to lower the flow rate of the sewage passing through the first treatment space 23 when a large amount of sewage flows in for a short time. Therefore, the sedimentation of the food waste mass contained in the sewage in the first space 233 is more effectively made. On the other hand, the simple wall 232 has a blocking function to prevent the sewage from flowing into the first processing space 23 in a specific situation in which the sewage flows back from the second processing space 26.

On the other hand, the sewage flowing into the second processing space 26 is raised while filling the inside. At this time, the food waste mass contained in the sewage is again filtered through the second manure 28. The second through hole 281 formed in the second manure portion 28 has a diameter smaller than that of the first through hole 251 formed in the first manure portion 25, thereby passing through the first manure portion 25. One food waste mass can be separated from the food waste mass having a diameter larger than the second through hole 281.

Sewage that rises through the second manure 28 is introduced into the second water level control space 27 over the second overflow portion 261. Thereafter, as shown in FIG. 6, the sewage flows into the bottom portion of the third processing space portion 29 through the second flow portion 271 formed under the second water level control space portion 27.

Thereafter, the sewage rising while filling the interior of the third processing space part 29 passes through the third through hole 292 provided in the third manure part 291, and again, after filtering the food waste mass, the outlet part 272. It is discharged to the outside through. At this time, the third through hole 292 has a diameter smaller than that of the second through hole 281 so that small food wastes not filtered by the second manure 28 may be separated from the sewage.

The height of the first overflow portion 231, the height of the simple wall 232, the height of the second overflow portion 261, and the height of the outlet portion 272 are sequentially lowered for the series of sewage flow.

In this way, the through hole of the filter plate provided in each processing space portion through which the sewage is gradually formed, the food waste contained in the sewage is sequentially filtered by size. Therefore, even a small amount of food can be separated from the sewage while maintaining a smooth flow of sewage.

On the other hand, as shown in Figure 8, the treatment space portion or the water level control space portion may be formed to be gradually smaller in area in the order of filthy water passes. In other words, the first purification module 2A, in which the sewage containing the large food waste mass is filtered, tends to inhibit the flow of the flow rate, thereby increasing the area in which the sewage is filtered to smoothly flow the sewage. .

Each treatment space portion may further include a filtrate 22 for chemical or biological filtration. At this time, the filtrate is any one selected from the group consisting of diatomaceous earth, acorns, activated carbon, and combinations thereof. In addition, various filtrates may be used as described above.

In the second embodiment of the present invention, while the backflow of sewage is actively prevented, the sewage is divided into multiple stages and is filtered through a plurality of times. This multi-stage filtration treatment has the advantage of improving the filtration efficiency by reducing the influence of microorganisms by chemical filtrate as possible by making biological filtration and chemical filtration by microorganisms apart from each other.

Meanwhile, FIG. 9 shows a third embodiment of the present invention.

The food wastewater treatment apparatus 10 according to the third embodiment of the present invention includes a housing 1, a partition 2, and a boundary 3. Here, the housing is the same as that of the first embodiment described above, and description thereof will be omitted.

The partition wall part 2 applied to the third embodiment has a treatment space part in which the introduced sewage gradually fills up and flows through the water, and the water level control lowers the level of the sewage overflowed from the treatment space part and flows it into another treatment space part. Purification module having a space portion is formed by connecting a plurality. Thus, the sewage introduced into the housing may pass through the plurality of purification modules in sequence and then flow out to the outlet.

The partition 2 according to the third embodiment may have the same configuration as the food wastewater treatment apparatus of the second embodiment described above. That is, in addition to the feature of the purification unit having a plurality of unit purifying means including a processing space part and a water level control space, the technical features shown in FIGS. 5 to 8 are applicable to the partition part according to the third embodiment as it is.

However, the lower part of the side wall close to the inlet 11 of the housing 1 of the partition part 2 of the third embodiment is largely open so that the sewage flows smoothly into the partition part 2. At this time, the lower part of the open side wall is lower than the height of the filter part.

The boundary part 3 is provided in the upper part of the partition part 2 so that removal is possible. The boundary portion forms a second flow path through which sewage can pass. The specific configuration of this boundary may be the same as that described in the first embodiment. However, the boundary portion is formed of a single flat plate.

This third embodiment is characterized in that the sewage introduced in a large amount at a time by the second flow path can be quickly discharged, and it is possible to efficiently filter and filter the food mass contained in the sewage through a plurality of steps sequentially. It has all the features.

On the other hand, Figure 10 to Figure 12 shows a comprehensive sewage treatment apparatus according to an embodiment of the present invention.

Referring to Figure 10, the comprehensive sewage treatment apparatus according to an embodiment of the present invention includes a crushing device 20, and further includes a drain cover 40 or a solid material separation and discharging device (30).

Specifically, sewage containing a large amount of food waste is discharged from the sink (S) of the home or restaurant. The crusher 20 breaks down the food waste contained in the sewage finely to help the food waste treatment device 10 or the solid waste separation and discharge device 30 to effectively separate or filter the food waste.

Specifically, in the crushing apparatus 20, a plurality of teeth are disposed in parallel with each other in a passage S1 through which filthy water passes, and a screw 210 having a plurality of teeth 220 for crushing the trash of the garbage is formed on the outer circumferential surface thereof. And a driving means 230 for rotating the screw 210.

Screw 210 may be installed in various numbers depending on the width of the passage. Preferably, two or more are installed in parallel with each other, and disposed to meet the sewage falling from the passage S1 and the food waste contained therein.

The drive means 230 is provided with a motor 240 for providing a rotational force, a gearbox 250 of a known configuration to increase the torque in response to the rotational force of the motor, and to rotate the neighboring screw 210 in the opposite direction to each other do. As a result, the neighboring screw 210 rotates rapidly in the opposite direction when the motor 240 operates, and the food waste mass passing between the neighboring screws is crushed by the teeth 220 crossing quickly.

In this case, the food waste masses finely divided through the crushing device 20 are separated from the food wastewater treatment device 10 described above, thereby lowering the food waste content in the final discharged sewage.

On the other hand, if the solid separation and discharging device 30 is further provided between the crusher 20 and the food wastewater treatment device 10, even if a large amount of food waste introduced from the sink (S), some food waste masses By discharging, the operation of the food wastewater treatment device 10 becomes more stable, and has an effect of increasing the period of collecting food waste separated from the food wastewater treatment device by reducing the amount of food waste mass separated from the food wastewater treatment device. do.

At this time, the sewage outlet of the solid matter separation and discharge device is preferably located higher than the food waste water treatment device so that the sewage can pass smoothly through the food waste water treatment device.

Although not shown, the solid separation and discharging device includes a pair of tapered compression screws arranged side by side, a driving means for rotating the compression screws in opposite directions, and an inner space part surrounded by the screws. The front portion may be provided with a separation unit configured to discharge the compressed food waste mass in front of the space and discharge the sewage into the lower portion, and a drying unit for drying the separated food waste mass with a heat source such as hot air. . Alternatively, the separation unit may be dedicated to various configurations such as a solid-liquid separator using a centrifugal force of a known configuration, and the drying unit may be dedicated to a method using various heat sources.

The sewage discharged through the solid separation and discharging device is significantly lower the content of food waste, it is possible to filter the finer food waste through the food waste treatment apparatus described above.

On the other hand, the drain cover 40 is located higher than the crushing device 20, and is coupled to the drain of the passage through which the sewage flows. In the figure, a drain cover is mounted at the bottom of the sink.

The drain cover 40 may block or open the drain hole, which is the upper end of the passage where the grinding device is installed. The crushing device 20 can be operated only in a condition that the drain hole is blocked by the drain cover 40. This eliminates the risk of injury from the crushing device, such as the user's finger, as the crushing device operates while the drain is open.

Specifically, referring to FIG. 12, the drain cover 40 is coupled to the drain and has one member 41 formed with an inlet 411 through which sewage passes, and rotatably coupled to the first member 41. It includes two members 42 for opening or blocking the inlet 411.

One member 41 is a cylindrical member coupled to the drain port, and a flange 414 is formed on the periphery of the drain port. In addition, one end of the one member 41 is formed of a plate, a hinge hole 412 is formed at the center thereof, and a plurality of inlets 411 are formed around the hinge hole 412. In addition, a sensor 413 that recognizes a magnetic force is mounted at one end of the inlet 411.

On the other hand, the two members 42 are plate members, the fitting protrusion 422, which is rotatably coupled to the hinge hole 412 of the one member 41, protrudes on the lower surface, and the handle 424 protrudes on the upper surface. . In addition, the two members 42 are formed with a passage opening 421 open in the thickness direction corresponding to the inlet 411 of the one member 41. In addition, the magnet 423 is built in the two members 42 at positions corresponding to the sensors 413 of the one member 41.

The fitting protrusion 422 of the two members 42 is coupled to the hinge hole 412 of the one member 41 coupled to the drain hole, and the drain cover 40 is assembled. One member 41 is rotatable about the hinge hole 412 with respect to the two members (42). The user can grip the handle 424 to smoothly rotate the two members 42.

The inlet 411 of the first member 41 and the passage 421 of the two members 42 overlap with each other according to the rotational angle of the two members with respect to the first member 41, and the drain cover 40 is opened in the thickness direction thereof. . In addition, when the rotation angle is changed, the inlet 411 and the passage 421 are shifted while the drain cover 40 blocks the drain.

When the inlet 411 and the passage 421 are positioned to be offset, the sensor 413 of the one member 41 and the magnet 423 of the two member 42 overlap up and down when the drain cover 40 blocks the drain. Are located. At this time, the sensor 413 detects the magnetic force emitted by the magnet 423 to know the rotation position of the two members 42 relative to the one member 41, and transmits an electrical signal to the control unit 50 provided separately Done.

Further, the handle 424 of the two members 42 has an arrow shape at one end so as to indicate the direction, and the indication mark 415 is formed on the flange 414 of the one member 41. When the indication mark 415 and the arrow of the handle 424 coincide with each other, the magnet 423 of the two members 42 and the sensor 413 of the one member 41 overlap each other up and down, and the drain cover is blocked. Becomes
