Conventionally, when a toilet is installed in a place such as a park, a river, or a camp site where water and sewage facilities are not supplied, the waste is usually stored in a tank, and when a predetermined amount or more is accumulated, a vehicle equipped with a suction device for treating wastewater is used. The method of collecting or transporting the portable toilet itself to a place equipped with a purification facility was mainly used.

In the case of such a portable or outdoor flush toilet, water and manure are accumulated in a storage tank without filtration, and thus, a cost problem occurs in the process of transporting and processing them, and thus, odor is not generated. In addition to discomfort to those who occur and use it, the discharge or flooding of contents due to unforeseen natural disasters such as floods, etc., without purification has led to secondary environmental problems.

In order to solve this problem, the spread of unpaid water free and flushed toilets has been actively made, but there is a limit to the use of smooth unpaid water free and flushed toilets due to the lack of technology for removing filtration and sterilization and odor.

For example, a conventional filtration device using only a mesh-type screen was used to purify wastewater or applied to filter manure generated in a flush toilet, but the microporous membrane of the mesh-type screen was applied to the impurities and suspended matter contained in the sewage. It was blocked by the filter, and the filtration function could not be maintained for a long time, and frequent mesh screen cleaning and replacement had to be performed.

The present invention is to install a filtration device is improved in the clogging phenomenon caused by the sediment and clings to the sediment and organic matter on the mesh screen at a low cost inside the general mobile toilet, by placing a tank for recycling water storage to the treated water to nature and rivers It is an object of the present invention to provide an economical and comfortable environment in which a toilet can be used without additional water supply by recycling treated water without being discharged.

The filtration apparatus is included in external wastewater. Xrin body for filtering the filtered water into the interior; A mesh screen having a fine mesh size covering the screen body; And a first air injection pipe through which the air is injected into the screen body, wherein the air injected by the first air injection pipe passes from the inside of the screen body to the outside through the meshed screen. At the same time, the water contained in the external sewage provides a water-free water free flush toilet including a filtration device to be filtered into the interior of the screen body.

In addition, the screen body preferably has a rectangular parallelepiped shape whose side surface is relatively wider than the upper surface.

The apparatus may further include a second air inlet pipe which injects air into the meshed screen outside the screen body so that solids or contaminants adhered to the meshed screen fall.

In addition, the flow rate adjustment tank and the treatment tank is preferably separated by the separation membrane and at the same time an opening is formed on the separation membrane to be connected to each other.

In addition, it is preferable to further include a treatment water outlet for moving the filtered water inside the screen body to another space.

It should be understood that there may be water and variations.

1 is a layout diagram including the configuration of each treatment step illustrating an example of an unpaid water free, zero discharge flush toilet with a filtration device according to the present invention.

As shown in FIG. 1, a flow rate adjusting tank 08, a treatment tank 09, provided with a filtration device, a flush toilet 03, a separator diaphragm 06, to provide a water free and discharge free flush toilet in a mobile toilet. It consists of a recycle water tank (02), an air supply blower (24), a self-priming pump (21) for treatment water movement, a control panel (12) for overall control, a UV sterilizer (37) and other components.

The manure washed in the flush toilet 03 of the toilet is transferred to the flow regulating tank 08. Anaerobic decomposition is made in the flow rate adjustment tank 08, and a filtration device is installed so that manure and sewage pass through the mesh-type screen 100 of the filtration device, and filtration is performed.

 The filtered treatment water is transferred to the treatment tank 09 through the separation partition along the treatment water discharge pipe 130 formed at the lower end of the filtration device.

In the treatment tank (09) through the biological anaerobic decomposition and aerobic decomposition, the water in a state that can be used as the washing water of the flush toilet is transferred to the recycle water tank (02) by the self-suction pump (21) inlet flow control valve ( 36 is flowed in and stored, and the flow rate of a predetermined amount is excessively circulated to the flow rate adjustment tank 08 through the treatment water circulation line 57, the sludge precipitated in the treatment tank 09 is conveyed sludge transfer pipe ( 55 is returned to the flow adjustment tank 08 again.

The sewage and manure before the treatment of the flow rate adjustment tank 08 and the treated water transferred to the treatment tank 09 are separated by a partition wall 06 so as to have a respective purification step, and the upper portion of the partition wall 06 The opening 07 is formed.

  The opening 07 is designed to discharge the gas generated in the bubble and decomposition process supplied to the flow rate adjustment tank 08 and the treatment tank 09, the discharged gas is additionally equipped with an exhaust fan 04 It moves through the communication and is discharged to the outside.

In addition, the additional UV sterilizer 37 is configured in the recycle water tank 02, so that a strong sterilization effect and odor removal is provided to provide a comfortable environment to the toilet users.

2 is a perspective view showing a filtration device.

As shown, there is shown a screen body for filtering the water contained in the sewage installed in the flow rate adjustment tank 08 of the water-free water free flush toilet equipped with a filtration device. The filtration apparatus is a form in which the mesh-type screen 100 is entirely surrounded on the outside of the screen main body 31 having a frame.

The first air injection pipe 110 is installed inside the screen main body and has a predetermined space through which a filtered water flows through the mesh-type screen, and the first air injection pipe 110 and the filtered treated water. It is open to the outside so as to configure the treatment water discharge unit 32 for moving to another space.

In addition, the screen body 31 is preferably configured in the form of a flat rectangular parallelepiped with a relatively wider side than the upper surface. This minimizes the area where sewage or manure sediment due to gravity acts and adheres to the upper surface of the meshed screen 100 and is discharged from the first air injection pipe 110 and the second air injection pipe 120. This is because it is possible to induce desorption of contaminants adhering to the side outer wall by the bubbles.

3 is a partial perspective side view of the filtration device. As illustrated, the first air injection pipe 110 having the discharge hole 140 is installed at the lower end of the screen body 31. Depending on the environment in which the filtration device is used and the density of the mesh-type screen 100, the first air injection pipe having various sizes of the discharge holes 140 and the gap between the discharge holes 140 can be selectively attached and detached. Do.

An open passage for moving the treated water filtered by the meshed screen 100 is formed at the lower end of the screen main body 31. It is easy to transfer the treated water to a storage tank 02 or a place having a next purification step by connecting the treated water discharge pipe 130 with the treated water discharge part 32 in the open passage.

The treatment water discharge pipe 130 connected to the treatment water discharge unit 32 has a water level interlocking function between the flow rate adjustment tank 08 and the treatment tank 09. It has a characteristic that it is easy to cope with an increase in flow rate because the treatment tank 09 performs a part of the flow rate adjusting tank 08 even when the inflow of manure and sewage is increased for a long time.

As an example of the purification step of the present invention, in the general mobile toilet structure, the flow rate adjustment tank 08 and the treatment tank 09 having a partition wall are installed at the lower end of the water-free washing water recycling toilet bowl, and the flow rate adjustment tank 08 and the The treatment tank 09 has a water level interlocking function by the treatment water discharge pipe 130 of the screen body 31.

 Anaerobic decomposition is performed in the flow rate adjusting tank 08. The anaerobic decomposition process has three stages: acid fermenter, acid decay, and alkaline fermenter. In the first process, hydrocarbons are mainly decomposed by the action of anaerobic bacteria, organic acids and nitrogen compounds are decomposed in the next process, and most of the remaining organic substances are decomposed in the final step, so that carbon dioxide gas and methane gas are generated and the sludge is stabilized.

In addition, a filtration device is installed inside the flow rate adjustment tank 08 to transfer the treated water filtered by the filtration device to the treatment tank 09, and the anaerobic and aerobic decomposition processes are performed. The aerobic degradation is oxidative decomposition through microorganisms in which contaminants (mainly organic substances) in water are biochemically decomposed by aerobic bacteria to make a stable substance.

In addition, in the case of a flush toilet installed outdoors, the use cycle is not constant, so as to prevent the microbial overgrowth and the disappearance of microorganisms due to excessive load due to the excessive or insufficient supply of microorganisms by the self-suction pump 21 Always supply a constant flow rate of the treated water to the recycled water tank (02), and supplies a constant flow rate of the treated water of the recycled water tank (02) to the flow rate adjustment tank 08 through the treated water circulation line 57, By circulating untreated organic matter at all times, there is an effect of enabling stable feeding activity of microorganisms.

In order to promote biodegradation through microorganisms, an aeration control operation may be performed, or an organic material to increase the activation of microorganisms or a method of raising the temperature may be used.

In addition, the intermittent operation of the aeration device to ensure the water quality that can be recycled as the wash water of the toilet while removing the suspended substances and nitrogen, phosphorus, which is the cause of eutrophication.

4 and 5 are enlarged conceptual diagrams showing the principle that water is filtered in a meshed screen. Air bubbles supplied through the discharge hole 140 of the first air injection pipe 110 and supplied into the screen main body 31 pass through the mesh-type screen 100 and exit out of the screen main body 31. At the same time to push out the contaminants adhered to the outer surface of the mesh-type screen 100, the outside of the filter device of the present invention by a force acting from the outside of the screen body 31 through the mesh-type screen 100 to the inside of the screen body 31 It is the principle that water is filtered inside.

 In the filtering device, the mesh type screen 100 may be preferably attached to or detached from the screen body by selecting a dense degree of the mesh according to an environment in which filtration is required. This is because contamination of the meshed screen 100 can be prevented by extending the life of the meshed screen 100 by selecting the degree of density of the meshed screen 100.

On the other hand, if the size of the mesh hole of the mesh-type screen used in the present invention is too large, the effect of the sewage purification disappears, if too small has the problem that the exchange of air and water does not occur, the interchange of air and water may occur It is desirable to make the size.

In addition, the mesh-type screen 100 may be configured to form a fixing plate and a fixing bolt for the detachable and fixed to the screen body 31 to enable a solid coupling.

In addition, the filtration chain is installed in a mobile toilet or a place for wastewater purification, and the traction chain is attached to a part of the screen body 31 so as to facilitate extraction during the replacement work of the mesh screen 100 or the periodic inspection of the filtration device during use. The fixing hole can be configured. As shown in FIG. 1, the towing chain 35 is connected to a fixing hole provided in a part of the screen body 31, and is fixed to the outside of the bathroom through the filtration membrane replacement orifice 11. It is possible to check the state of the screen body 31 or to replace and repair.

6 and 7 are perspective views of a filtration device of another embodiment constituting the second air injection pipe 120. The second air injection pipe 120 surrounds the outer surface of the lower end of the screen main body 31, and forms a discharge hole 140 similarly to the first air injection pipe 110. Bubbles passing through the discharge hole 140 rises in the vertical direction from the discharge hole 140 and prevents the sediment deposition and cleaning of the mesh screen 100.

In order to enhance the installation effect of the second air inlet pipe 120, when the shape of the screen body 31 is formed in a trapezoidal shape of the inverted trapezoidal shape narrower than the upper surface in the flat rectangular shape having a wider side surface than the upper surface. And, the sedimentation in the gravity direction can reduce the degree of clogging the mesh-type screen 100, the bubble supplied from the second air inlet pipe installed in the lower portion of the screen body 31 is raised by the force to rise in the vertical direction Since it moves along, it can bring a cleaning effect on the outer wall of the large mesh-type screen 100.

The meshed screen 100 is a structure capable of cleaning the meshed screen 100 by supplying air to the first air injection pipe 110 and the second air injection pipe 120 by an intermittent movable blower 24. It is.

A single blower 24 is supplied to each air injection pipe at the same time by supplying air to the first air injection pipe 110 and the second air injection pipe 120, or the first air injection pipe 110. And a second blower in the air inlet pipe 120, so that the cleaning time and the frequency of the mesh screen 31 can be determined in detail by the control panel 12 according to the amount of solids generated. You can make adjustments.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains.
