Description

TECHNICAL FIELD [0001] The present invention relates to a high-efficiency non-reflux portable toilet which can recycle sewage water. BACKGROUND OF THE INVENTION < RTI ID = 0.0 >

More particularly, the present invention relates to a highly efficient non-reflux portable toilet for recycling wastewater contained in excreta and recycling the urine.

Generally, movable toilets are mainly installed in the public areas such as tourist sites, camping areas, parking lots, parks, outdoor rest areas or disaster areas. Such a portable toilet is not only convenient to install and move, but also can be conveniently installed at a place where many people are occasionally and momentarily concentrated, and the installation ratio is gradually increasing.

A conventional portable portable toilet is provided with a storage tank in which manure is stored in the lower portion of the toilet. When a certain amount of manure is charged in the storage tank, the manure is extracted using a collection vehicle, and the extracted manure is separated from a separate manure treatment plant or landfill To be processed.

However, the above-mentioned conventional portable toilet has a problem that not only bad odor is generated by the manure stored in the storage tank but also hygienic condition is very poor by inducing the habitat of flies and pests which cause various diseases. In addition, there is a disadvantage in that it is difficult to dispose of the manure stored in the storage tank in an area where the manure collection vehicle is difficult to reach, and the manure extracted from the storage tank has to be treated separately.

In order to solve the above-mentioned problem, various technologies have been researched and developed so that the movable toilet itself can treat the manure to some extent.

For example, there is a natural fermentation type toilet (natural fermentation type) and a foaming type (fossil type) toilet equipped with a bubble generator as a means for reducing the odor inside the toilet, but the manure is accumulated in the storage tank and exposed And it is unsanitary because of the incidence of insect pests. Moreover, it is inconvenient to collect manure and sewage on a regular basis, and it becomes a secondary environmental pollutant source when disposal of collected manure and sewage, It is difficult. Particularly, in the case of a natural fermentation type toilet, it is required to supply microorganisms, a long time is required for natural fermentation, and there is a problem in that it can not be treated in winter. In addition, in the case of the foam-generating toilet, the maintenance cost is increased due to continuous supplementation of the foam-generating agent, but the effect is insignificant.

Further, in order to solve the above-mentioned problems, a flush toilet to be treated and discharged through a purified water tank buried underground can be applied. In this case, since the purification tank needs to be cleaned periodically and the treatment efficiency is relatively low, There is a problem that it becomes an environmental pollution source, and there is a problem that a separate water supply facility for supplying water supply is required.

Accordingly, there is an urgent need to develop a portable toilet which can reduce the maintenance cost and can reuse the waste water without separately treating the problems of the toilet according to the related art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 to 12, a high-efficiency non-return type portable toilet for recycling sewage according to an embodiment of the present invention is for separating and treating waste water from waste discharged from a toilet 10. [ The sewage recycling high-efficiency non-reflux portable toilet is provided with a waste separation unit 110, a faunal treatment tank 200, a first waste water treatment unit 300, a second waste water treatment unit 400, a wastewater treatment tank 500, And a plant treatment tank 600.

Here, the toilet 10 is, for example, a portable toilet, and includes a toilet space 12 in which a toilet 20 and a water storage tank 22 are installed, an excrement separation unit 110, a faunal treatment tank 200, And a storage space 14 installed in the first waste water treatment unit 300 or the like, and may be formed at upper and lower portions, respectively, with the toilet floor as a boundary.

4 to 7, the waste separation unit 110 includes a base 112, a receptacle 140 which is installed on one side of the bottom of the base 112, An opening and closing plate 130 for opening and closing the lower part of the receptacle 140 and a feed driving part 120 for moving the opening and closing plate 130.

The base 112 is a box-shaped support member whose top surface is opened, and a wastewater guide portion 114 is provided at one end to provide a path through which wastewater separated from the wastes is discharged. As shown in FIG. 1, since the slurry separation unit 110 is installed to be inclined, the wastewater separated from the slurry collects in the wastewater guide portion 114 formed at one end and flows along the wastewater guide portion 114.

Therefore, when the waste separation unit 110 is installed such that the end of the waste water guide 114 is located above the area of the first waste water treatment unit 130, the waste water separated from the waste is flowed into the first waste water treatment unit 130 I go in.

A slot 115 is formed at the bottom of the base 112 and a pair of ribs 116 project perpendicularly to both sides of the slot 115 to allow the rod 122 to extend within the slot 115 Space. 6, the receptacle 140 is formed in a box shape and has a connecting tube 142 formed on the upper surface of the body 141 to be connected to an outlet of the toilet bowl 20 as shown in FIG. An opening 143 is formed, and a discharge hole 144 is formed at the lower end of the side wall.

According to this structure, the wastewater from the effluent flowing through the connection pipe 142 is discharged through the discharge hole 144, and the solids are caught in the discharge hole 144, so that the solid matter of the excrement is naturally separated from the wastewater.

A guide plate 145 may be provided between the receptacle 140 and the waste water guide 114 to smooth the flow of sewage.

As described above, in order to perform the function of separating the solid matter of the excrement from the waste water, the opening 143 formed in the lower surface of the receptacle 140 needs to be blocked. To this end, the opening and closing plate 130 is installed .

6, channels 132 and 132a through which wastewater flows are formed on both sides in the width direction of the opening and closing plate 130, and open grooves 134 are formed at one end in the longitudinal direction, 132, and 132a, respectively.

4, a bracket (not shown) protrudes from the bottom of the opening / closing plate 130, and an end of the rod 122 extending from the cylinder 121 is fixed to the bracket, The opening / closing plate 130 moves according to the movement.

Therefore, when the rod 122 returns and the opening / closing plate 130 is pushed, the opening 130 is opened, so that the excrement is dropped through the opening 143 as it is. On the other hand, when the rod 122 is drawn out, since the bottom of the opening and closing plate 130 blocks the opening 134 against the opening 143 of the receptacle 140, the excrement is piled on the bottom of the opening and closing plate 130, And the wastewater is discharged through the discharge hole 144 of the collection box 140.

Here, the feed driving unit 120 includes a driving unit 121 for driving the rod 122 and the rod 122 to reciprocate. The feed drive unit 120 includes various units including a hydraulic cylinder, a linear motor, and a lead screw, and reciprocates the open / close board 130.

The faecal treatment tank 200 is installed at a lower portion of the faeces separating unit 110 to receive a falling faeces. In this feces treatment tank 200, microorganisms and the like are injected and naturally decomposed to reduce the amount of feces.

The first sewage treatment unit 300 may be installed adjacent to the faeces treatment tank 200. The first waste water treatment unit 300 is disposed under the waste separation unit 110 and receives the waste water (urine) separated from the waste separation unit 110 and processes the waste water first.

8, the first waste water treatment unit 300 includes an oxidation reaction tank 310, a UV lamp 320, an ozone supply unit 330, a partition wall 340, a ship ozone strainer 350, And an ozone circulation path (360).

The oxidation reaction tank 310 is formed with a waste water inlet 311 at an upper portion thereof and a waste water outlet 313 at a lower end thereof. An ozone discharge port 315 is formed in the upper part of the oxidation reaction tank 310. At least one UV lamp 320 is installed inside the oxidation reaction tank 310 to irradiate UV light. The light of the UV lamp 320 reacts with the supplied ozone to generate an OH radical.

Further, it is preferable that a reflective surface 315 for reflecting the light of the UV lamp 320 is further provided on the inner wall surface of the oxidation reaction tank 310. The reflection surface 315 may be formed by coating a metal material on the inner wall surface of the oxidation reaction tank 310 or by providing a metal plate. Thus, by further including the reflecting surface 315, the UV light in the oxidation reaction tank 310 can be reflected to improve the photodegradation efficiency of the ozone. Therefore, the capacity of the UV lamp 320 can be reduced, It is advantageous in that sufficient energy can be secured for sewage treatment.

The ozone supply unit 330 includes an ozone generator 331, an ozone diffuser 333 installed inside the oxidation reaction tank 310, and an ozone supply line 335 connecting the ozone generator 331 and the ozone diffuser 333 Respectively. The ozone diffuser 333 is installed in the lower part of the inside of the oxidation reaction tank 310 and serves to dissolve the supplied ozone in the wastewater. At this time, it is preferable that a plurality of partition walls 340 are arranged in a zigzag manner to prevent the dissolved ozone from rising rapidly. Therefore, it is possible to prevent the ozone from rising rapidly and to increase the dissolution rate of the supplied ozone.

The ozone depleted zone 350 is for treating and discharging ozone discharged through the ozone discharge port 315, that is, un-dissolved ozone, and may have a structure filled with activated carbon and an ozone adsorbent.

The ozone circulation path 360 is connected to one end of the ozone discharge port 315 and the other end of the ozone circulation path is connected to the lower part of the oxidation reaction tank 310, .

The first wastewater treatment unit 300 may further include a hydrogen peroxide supply unit for supplying hydrogen peroxide (H ₂ O ₂ ) into the oxidation reaction tank 310. Therefore, hydrogen peroxide may be supplied as an oxidizing agent to the oxidation reaction tank 310. [ Such a hydrogen peroxide supply part is not necessarily a necessary component but can be selectively applied in accordance with the use environment, the amount of wastewater to be treated, the capacity (size) of the treatment facility, and the like.

The first wastewater treatment unit 300 having the above configuration is for treating wastewater (urine) by applying a so-called 'Advanced Oxidation Process' (AOPs) using ozone and UV light, Material and chromatic oxidation and removal processes can be achieved.

On the other hand, in order to more easily understand the wastewater treatment process by the first wastewater treatment unit 300, advanced oxidation processes (AOPs) will be described in more detail.

Advanced advanced oxidation processes (AOPs) are processes that produce hydroxyl radicals by oxidizing the target material using OH radicals with strong oxidizing power and finally mineralizing them in the form of CO ₂ or H ₂ O Therefore, it can be divided into several kinds. AOPs are typically represented by O ₃ / High pH AOP, O ₃ / Perexone AOP, O ₃ / UV AOP (Photolysis), hydrogen peroxide / iron salt AOP (Fenton AOP), hydrogen peroxide / UV AOP , And AOP using the same.

The common feature of these AOP technologies is that they are based on OH radicals generated from intermediates rather than expecting treatment effects from directly injected oxidants, and they have a much stronger oxidizing power than conventional oxidizing agents such as chlorine, chlorine dioxide and potassium permanganate Ozone and the like can be applied more economically and efficiently in water treatment than in the case of using alone, and it is effective for decomposing a large amount of organic compounds by maximizing the production concentration of OH radicals. In other words, OH radicals are far superior to other oxidizing agents in their oxidative power, and they react non-selectively, so they can rapidly decompose degradable materials such as organic compounds.

Table 1 below shows the comparison of the oxidation potentials per oxidant.

Oxidant Oxidation Potential OH radical 2.80 ozone 2.07 Hydrogen peroxide 1.77 Permanganate 1.68  Goat 1.36

UV / H ₂ O ₂ (UV / hydrogen peroxide, UV / Hydrogen Peroxide) among the above-mentioned AOP technologies will be described as follows.

The UV / H ₂ O ₂ process is a powerful oxidizing power of various free radicals (HO ₂ , OH, etc.) generated from the oxidizing agent H ₂ O ₂ by the catalytic action of injected UV. It is the process of ultimately oxidizing pollutants to harmless compounds such as CO ₂ and H ₂ O, mineralacids or converting them into biodegradable materials.

H ₂ O ₂ can be applied to treatment of wastewater containing a large amount of refractory substances, organic compounds, cyanide compounds, metal complexes, sulfides and odors. In addition, it is the most economical and easy to handle among the various oxidizers, and has the advantage of being environmentally safe because it is decomposed into harmless H ₂ O and O ₂ in a natural environment without generating toxic substances or coloring materials. However, only the oxidation of the H ₂ O ₂ are due to the reaction from the ideal concentration of the H ₂ O ₂ to fit a very low rate of oxidation of organic compounds having an aromatic chlorine compound (chlorinated aromatic compounds) or long chain is ineffective. Therefore, it is possible to effectively treat wastewater through photochemical induction oxidation which generates OH radicals as a strong oxidizing agent from the photolysis of H ₂ O ₂ by UV (UV / H ₂ O ₂ process).

H ₂ O ₂ is mainly photolyzed directly with OH radicals by UV at wavelengths below 300 nm (typically 253.8 nm) as follows:

H ₂ O ₂ + hv → 2OH

The OH radicals generated at this time show an oxidation potential of 2.80 V at pH = 0, which is much higher than 1.77 V of H ₂ O ₂ . In addition, the OH radical reacts non-selectively with organics at a high reaction rate of 10 ⁹ M ^-1 s ^-1 . The resulting OH radical reacts with the injected H ₂ O ₂ to form other radicals, and the radicals are again coupled to H ₂ O _2, as shown in the following equations.

OH - + H ₂ O _{2 -} > HO _{2 -} + H ₂ O

And OH + HO ₂ ^- → HO ₂ + and OH ^-

2HO _{2 -} > H ₂ O ₂ + O ₂

In the case of the present invention, ozone / UV AOP is applied, and the process of directly injecting hydrogen peroxide in the hydrogen peroxide / UV AOP is omitted, and the result of the initial reaction in which ozone is photo- It is characterized in that it can be used as an oxidizing agent by generating OH radical by using generated hydrogen peroxide.

That is, 'Ozone / UV AOP' applied in the present invention is an AOP using the principle that ozone is photolyzed by ultraviolet energy irradiated from a UV lamp to generate OH radical through hydrogen peroxide (H ₂ O ₂ ) The process is shown in FIG.

In the case of the present invention, ozone is supplied and dissolved in the oxidation reaction tank 310 while the UV lamp 320 is installed in the oxidation reaction tank 310. The remaining ozone dissolved in the liquid state is decomposed in a comparatively short time in the liquid state to become oxygen (O ₂ ) and generator oxygen (O), and then reacts with the liquid to form hydroxide (OH ₂ ^- ) and superoxide Radicals (O ₂ ^- ). The dissolved ozone is photolyzed by the UV light (ultraviolet energy) irradiated from the UV lamp 320 installed in the oxidation reaction tank 310, and hydrogen peroxide (H ₂ O ₂ ) is produced as an intermediate substance as a result of the initial reaction. The process by which dissolved ozone is photolyzed and hydrogen peroxide (H ₂ O ₂ ) is produced as an intermediate can be understood through the following reaction equations.

O ₃ + hv + H ₂ O -> HO ₂ + OH

HO ₃ + OH - > 2HO ₃

O ₃ + HO ₂ -> OH + ₂ O ₂

O ₃ + OH - > - HO ₂ + O ₂

HO ₂ + HO ₃ -> H ₂ O ₂ + O ₂

HO + HO ₂ - > H ₂ O + O ₂

OH + OH - > H ₂ O ₂

Hydrogen peroxide thus produced as an intermediate produces OH radicals in the same path as PEROXONE AOP. In terms of OH radical generation, PEROXONE AOP and Ozone / UV AOP are identical. However, in the case of PEROXONE AOP, hydrogen peroxide is artificially injected, whereas in the case of Ozone / UV AOP, the production method of the present invention is different in that hydrogen peroxide is directly produced by ozone photolysis. Therefore, as described above, the present invention advantageously eliminates the need to install a hydrogen peroxide supply unit, and the hydrogen peroxide supply unit can be selectively applied to a user.

As described above, in the first wastewater treatment unit 300, wastewater can be treated using OH radicals generated by photolysis to oxidize and remove pollutants and chromaticity in the urine.

Then, the wastewater treated first is supplied to the second wastewater treatment unit 400 and processed in a second order to remove residual chromaticity, turbidity and odor.

In addition, spacers 750 may be provided between adjacent partition walls 740 at regular intervals along the longitudinal direction.

The spacers 750 are spaced apart from each other by a predetermined distance while maintaining the same level of a pair of flat plates having a height lower than the height of the barrier ribs 740. A filter material 810 is formed in the inner space 713 of the spacer 750, Is not filled.

Typically, the wastewater flowing from the through-hole 742 flows along the upper surface of the filter material 810 without being absorbed into the filter material 810 and may be discharged to the opposite passage hole 842. In this case, Little effect is seen.

In this case, by providing the spacer 750, even when the wastewater flowing from the passage hole 742 is not immediately absorbed into the filter material 810, the spacer 750 flows after a certain distance along the upper surface of the filter material 810, To be absorbed into the filter material 810 by falling into the space 713 formed by the filter material 810.

According to this embodiment, in addition to the advantages of the above-described embodiment, the distance through which sewage flows in the canister 700 can be substantially increased to further increase the filtration efficiency.

Further, by providing the spacer 750 between the partition walls 740, the introduced wastewater can be absorbed into the filter material 810 to improve the filtration efficiency

As described above, the treated water (wastewater) that has been secondarily treated in the canisters 440 and 700 is transferred to the treatment water tank 500.

In the treatment water tank 500, E. coli, ordinary bacteria, and the like are removed using a disinfectant or the like, and the overflow water in the treatment water tank 500 is supplied to the plant treatment tank 600 to remove nitrogen, phosphorus, and the like. That is, the plant treatment tank 600 is installed adjacent to the treatment water tank 500, and plants are planted in a state where the soil is filled in the plant treatment tank 600. Thus, by the so-called natural purification method (purification using plants and soil microorganisms) 500) can be treated. That is, the overflow can be introduced into the soil in the plant treatment tank 600 through the pipe. The overflow water flowing into the plant treatment tank 600 is biologically decomposed and treated by soil microorganisms and adsorbed by the soil particles. It can also be absorbed and processed into vegetation through plant roots. Therefore, residual pollutants (nitrogen, phosphorus) contained in the overflow can be treated naturally.

The treated water in the treatment water tank 500 can be pumped by the pump 510 and supplied to the water storage tank 22 of the toilet for reuse.

As described above, according to the sewage-reusing high-efficiency non-reflux portable toilet according to the embodiment of the present invention, the urine discharged from the feces and the separated urine are treated first, and the first treatment is performed by the AOP purification process using ozone and UV, The material and chromaticity can be oxidized and removed for processing. Thus, when the urine is treated by the AOP purification process using ozone and UV, the pollutants in the urine are oxidized and treated effectively and reliably over a short period of time in comparison with the conventional natural fermentation type, can do.

Then, the first processed urine (wastewater) is handed over and processed in a step-wise manner using a second-order filter in the second wastewater treatment unit 400, so that residual chromaticity, turbidity and odor can be removed.

In the third treatment tank 500, it is possible to treat E. coli and common bacteria and then re-supply the same to a toilet or the like, so that water necessary for the toilet can be replenished, and water supply cost can be reduced.

In addition, since the overflow water in the treatment water tank 500 moves to the plant treatment tank 600, it is possible to naturally treat residual foreign matter such as nitrogen and phosphorus, thereby fundamentally preventing contamination of the surrounding environment.

That is, in the case of the present invention, the urine (sewage) coming out from a toilet or the like is not treated and discharged, but it can be supplied to a toilet and reused, thereby overcoming the water shortage environment around the toilet, It is very economical because it can reduce the supply cost. Further, since the processed urine (wastewater) can be reused, it is possible to fundamentally solve the problem of environmental pollution or the like that occurs when the urine is discharged.

In addition, since the solid side urine is separated and the urine is treated and reused, the amount of sludge of the solid side can be effectively reduced, thereby reducing the overall maintenance cost including the disposal cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
