Description

Closed dry toilet system and method for treating toilet waste

The present application is directed to a closed dry toilet system with a composter.

In addition, the application relates to a method for treating toilet waste in said dry toilet system.

Background A dry toilet is a toilet where debris, ie toilet waste, is not flushed with water, but collects in a container, tank, pile, pit or similar.

Toilet waste can be further treated in different ways: it can be removed and composted, or - dried.

The dry toilet can be located indoors or outdoors.

Dry toilets are often associated with odor problems caused by toilet waste.

In water-operated toilets, the toilet waste is transported far from the toilet unit, such as a seat or urinal, as a result of rinsing, and the toilet unit is cleaned - at the same time.

In addition, the water in the piping prevents odors from entering the toilet facilities.

The odor problem is one of the factors limiting the spread of dry toilets.

Dry toilets are usually implemented as a unit of a single toilet unit, in particular a toilet seat, and are difficult to combine.

The maintenance of multi-toilet units is problematic, especially in public areas, and S toilet waste must be collected separately and transported elsewhere from the toilet facilities.

In general, the dry toilet seats in use in N are quite large, which further 5 makes it difficult to build and manage larger entities.

N 30 I Brief summary a & The present application describes a closed toilet system which 0 enables the construction of multi-toilet units and the efficient management and treatment of the resulting S 35 toilet waste.

The application concerns a closed dry toilet system comprising - two or more dry toilet units,

-the composter of at least one enclosed toilet waste conveyor sealedly connected to the dry toilet units, the composter having an inlet and an outlet sealedly connected to the at least one toilet waste conveyor and the composter being - - arranged to receive - from the conveyor has one or more sensors, such as an electric sensor, for detecting the temperature of the compost combined with one or more control units, and means for controlling the temperature, such as one or more heaters or coolers, connected to one or more control units, the control unit being arranged in response to one or more adjusting means for controlling the temperature to obtain the desired temperature in the compost for the desired treatment time, and optionally a container for the final product, which may be sealed to the outlet of the composter.

The application also relates to a movable transport container, such as a container, comprising said closed dry toilet system. The application also relates to a method for treating toilet waste, which method comprises - providing said closed dry toilet system or a portable transport container, - composting toilet waste accumulated in a composter, preferably above 40 ° C, such as above 50 ° C, or above 55 ° C or above 60 ° C, sufficient time to - hygienise the toilet waste, and - optionally transfer the hygienised toilet waste to the final product container.

S N The main embodiments are set out in the independent claims. Other N embodiments are set out in the dependent claims. The embodiments set forth in the claims and specification may be freely combined, unless otherwise indicated. a & Because the dry toilet system is closed, it allows precise control of odor nuisance as well as the 0 toilet waste treatment process. The entire process takes place in a> 35 - closed system, so that no untreated waste enters the system, nor does external material enter the process, which could affect the quality of the final product. Composted toilet waste is discharged from the system and treated in a controlled manner and to the desired treatment level.

The practical end product is a hygienized material that is free of, for example, living pathogens. Its handling is therefore safe and does not cause odor nuisance.

When a vacuum is created in the toilet system, the odors cannot spread through the toilet units, but can be led outside the system by other means.

It is possible to implement a system of several toilets in a space-saving manner and - especially on one level. Toilet units do not require separate tanks, which take up space and require emptying. When a suitable toilet waste conveyor, such as a screw conveyor, a vibrating conveyor or a cola conveyor, is used, the toilet waste can be transported in a substantially horizontal plane from the toilet units. In this case, the system does not require additional space in the vertical direction, such as the construction of pipelines between the layers. It is possible to build such a system, for example, in a movable tank, such as a container, or in another existing space, such as a building or the like. This makes it possible to provide toilet systems for events or areas where the need arises. Examples of events are, for example, public events such as festivals or other outdoor events. For such - events - mobile dry toilet systems can be = delivered = required - for example, implemented in containers. Another example of the need for toilet systems is, for example, disaster areas, where a large number of people have to be accommodated, for example, in a camp or other temporary accommodation. Such areas can either be supplied with ready-made portable dry toilet systems, or the systems can be built quickly, for example in an existing building that was not originally designed as a toilet space. Since there is no need to install separate piping in the buildings, in practice only a base, such as a floor or even a relatively flat N ground, is required to implement the toilet system N. N 30 I The toilet system can be implemented in such a way that the toilet waste is recovered = all useful and virtually water remains, which can be further recycled & or even discharged to the ground or sewer. For example, composite material, nutrients such as nitrogen, potassium and / or phosphorus, carbon dioxide,> 35 - water and / or heat can be recovered. The heat generated in the composter can be utilized in other parts of the system, for example to sterilize or evaporate the liquid, to heat the toilets or to generate energy. An efficient toilet system enables efficient waste treatment and high hygienic air to add chemicals, such as those used for sterilization or cleaning. The system can operate continuously. The operation of the toilet system can be controlled on the basis of the information collected by the sensors in the system, whereby in response to the collected information, control measures, manual or automated, can be performed, which enable the desired operation of the system and the desired treatment of toilet waste. In this way, the desired end product can be obtained, regardless of the starting materials. Since the composition of the accumulated toilet waste can vary greatly, for example in terms of its urine and faecal contents and other material entering the toilet waste, it is advantageous to be able to control the operation of the system so that the process is not disturbed and the final product obtained is desired. For example, portable toilet systems delivered to beer festivals collect relatively much more urine than feces compared to systems delivered to another type of public event. Toilet waste can also contain significant amounts of material other than urine or feces, such as toilet paper, other paper, tampons, sanitary napkins, vomiting, water, beverages, debris, or the like, which toilet users can throw into toilet units. Thus, it may be necessary to eliminate or reduce one or more of these in order to achieve the desired composition of the final product. Description of the Drawings Figure 1 shows an exemplary dry toilet system built into a mobile container; Figure 1a shows those seen from above the dry toilet system and Figure 1b shows it from the side

S N Figure 2 shows exemplary toilet seats 2a and 2c seen from the side 5 and 2b seen from above V 30 I Detailed description a & The application describes a closed dry toilet system which, according to Example 0, can be functionally divided into a toilet compartment and a toilet waste> 35 processing compartment. These can be physically separate spaces, for example in different rooms, in different portable tanks or separated by a wall, or they can also be arranged in the same space. In one example, the toilet compartment is in one mobile container, such as a container, and the processing compartment is in another mobile container.

in a container such as a container. In another example, both the toilet compartment and the process compartment are in the same mobile container, such as a container. The dry toilet system can be batch or continuous.

5 —The dry toilet system comprises at least one dry toilet unit. The toilet system may have several dry toilet units, preferably two or more. A dry toilet unit may mean any toilet unit suitable for a dry toilet, such as a toilet seat, a squat (urinal) urinal / urinal, an opening in a plane, or the like. Such a toilet unit is arranged to operate without rinsing or with low water. The toilet system may have one or more toilet seats and one or more urinals in the same space as the toilet compartment. For example, each toilet unit, such as a toilet seat, may be in its own booth, which may be a door, or in a wall-separated space. Booths or other similar spaces may be relatively dense, such as delimited on all sides by walls and / or doors, and preferably without gaps below or above. In this case, it is possible to ensure the flow of air from the air intake opening at the top of the booth, such as the roof, through the toilet seat to the system. Two or more toilet units may be connected together through their outlets. Preferably, the toilet units do not have containers for toilet waste. Dry toilet units, such as waterless toilet seats, squats or urinals, may comprise a water and / or dirt repellent coating, for example in areas prone to faeces or urine.

Figures 2a and 2b show an exemplary toilet seat. The toilet seat 10 has a seat portion with a rim for receiving the user, a recess 44 below the rim at the top for receiving toilet waste, and an outlet 46 opening into the recess S through which toilet waste exits or is removed from the N toilet seats, and is preferably led elsewhere. The outlet 46 can be N covered with an openable and closable flap, for example manually or automatically N30 - openable and closable. The outlet may be connected to a pipe, conduit, conveyor or the like for conveying toilet waste elsewhere. The toilet = seat may have a sensor, for example a pressure sensor, an optical sensor or a switch, which detects the user and / or the toilet waste, and which, depending on the status of the sensor, the system may, for example, switch the toilet waste on the conveyor. > 35 A urinal or urinal, which may mean the same, has an open trough, recess or reservoir at the top arranged to receive urine. This further opens an outlet through which the urine is drained or removed, and is preferably diverted elsewhere. The outlet may be connected to a pipe, conduit or the like to direct urine elsewhere. The urinal may have a sensor, for example an optical sensor such as an infrared sensor, which responds to the proximity of the user and which is connected to one or more control units, which in turn may be arranged to open or close the urinal outlet and / or control urine in the system. For example, when the user is at the urinal, the outlet valve opens, and correspondingly, when the user exits, the valve closes, thereby reducing or preventing additional odors from entering the toilet facilities. The urinal may also have a membrane closing the outlet, which is - arranged to open from the pressure of the urine. The membrane closes when the urine flows out. The membrane is simple and can operate independently, and therefore does not require, for example, additional institutions or guidance. The toilet seat may further comprise means for separating urine and faeces, such as the structure of the toilet seat or the interior part therein, in which case it is referred to as a separating dry toilet. Such a solution is shown in Figure 2b. In this case, the urine and faeces can be directed to different places and / or treated separately, preferably in different ways. For example, the separating toilet seat may have a first opening, recess, or tray 48 for receiving urine in the front of the seat 10, and a second opening, recess, or tray 46 for receiving feces in the back of the seat 10, as viewed from a seated user. A separate outlet opens from both compartments or recesses through which the separated urine or feces is removed or removed and can be led or transported elsewhere, and preferably further processed, for example by separating one or more substances. Said first and second openings, recesses or compartments can be realized as a separate removable separation tray, which contains both and can be placed in and removed from the toilet seat, for example as N separation trays made of plastic. The toilet seat may have a structurally and / or functionally N-like sensor and / or valve, or an outlet closure membrane, as described above in connection with the urinal N 30, and the toilet seat may be arranged to operate in a similar manner with respect to urine.

a & In one embodiment, the dry toilet system comprises means for separating urine from the feces, such as in a dry toilet unit or toilet waste conveyor, and a piping for directing urine. Urine is discharged from a solid, such as faeces and / or other solids, and / or may be discharged from a processing tank and / or a composter. Preferably, the urine is already separated in the urinal or toilet seat so that it does not have time to mix with the faeces and form a contaminated leachate. Urine, either separated at some point or from urinals, can be directed to a container, for example a urine collection container, a treatment container and / or further processing. The urine can be further processed, for example, by recovering substances such as phosphorus, potassium and / or nitrogen, and / or - by precipitating the above and / or other substances, filtering insoluble substances, and / or performing other purification steps to obtain purified urine, preferably water. Water or aqueous liquid can be used, for example, to flush or wash the system during the maintenance phase. Although the toilet system is anhydrous, it may from time to time be necessary to add water or the like to the system to clean it, for example, through toilet units. Such a flushing or maintenance step may be automated to be performed at certain intervals or as needed, preferably when the system is not otherwise in use. The rinsing water may eventually end up in a processing tank or composter where it moistens the material to be composted.

The toilet system comprises at least one toilet waste conveyor 14, 14a, 14b, which is sealedly connected to at least one dry toilet unit. The conveyor is housing, and preferably the housing 42 is sealedly connected to at least one dry toilet unit 10 and, for example, to the housing of another conveyor, whereby - the system can be implemented closed. Enclosure means any suitable structural solution that delimits or separates the conveyor from its own space, which can be isolated from an external space. The enclosure may have walls around the conveyor to form a tubular structure, one or both ends of which, or parts of the enclosure walls, may be open and connectable - to toilet units, other encapsulated conveyors, tanks or composers. An end of the housing which is not connected to anything can be closed, for example, by an S wall, thus ensuring the tightness of the housing.

O

N S “Closed” system in this context means that in the toilet system N 30 - at least the connections I between the toilet unit (s) and the composter are sealed, especially during operation. The parts of the system are thus “sealed = connected” to each other, such as at least the toilet unit (s), the conveyor (s) or their housing (s) and the composter (s), but also other possible parts of the system 0, such as the processing tank (s). (s),> 35 - piping (s), enclosures, system-related connections, such as means for adding or removing one or more substances, connections for one or more sensors and / or other connections. Tightly combined may mean airtight or watertight, or substantially airtight or watertight, but complete airtightness or watertightness is not always necessary, as the vacuum in the system reduces the transmission of odors from, for example, joints. However, the system is open, at least occasionally, via toilet units, which is necessary for the operation of the system and, for example, for suction of vacuum into the system. The container (s) for the final products, such as the container (s) for the composted product and / or urine, are preferably at least partially and / or occasionally closed, such as during use. In general, the outlet or outlets of the system through which the treated toilet waste and / or the collected and / or treated urine can be removed, or the containers connected to them, can be opened and / or emptied.

In one implementation, several toilet units, in particular seat parts, are connected to the same conveyor. One or more toilet units, preferably a toilet seat, may be connected to the same conveyor so that a conveying portion of the conveyor, such as a screw, spiral, chute, trough, trough, level or recesses, passes or passes through the outlet exits of the toilet units, e.g. the toilet waste leaving through the outlet enters the conveyor and is transported out of the toilet unit. The conveying portion of the conveyor may be coated with a dirt-repellent coating, or at least a portion thereof may be made of a dirt-repellent material, such as a Teflon coating (polytetrafluoroethylene) or a derivative thereof, abs plastic, or the like. The seat part may have been modified to accommodate the conveyor. For example, an opening 41 for the conveyor 14 may be formed in the lower part of the seat part, as shown in Fig. 2a. The conveyor 14 is housed in a housing 42 which is sealedly connected to the toilet seat 10, in particular to its outlet 46. For example, the conveyor 14 has a trough 40, for example a belt conveyor, the edges of which are arranged to rise. Figure 2b shows in dashed lines the position of the conveyor in relation to the seat part, i.e. the conveyor passes through the toilet seat, and may have more than one toilet seat connected to it by this principle. The conveyor N of the toilet waste can be any suitable conveyor arranged to transport the N toilet waste, in particular faeces, to the desired location. The conveyor may be a mechanical N 30 conveyor connected to the actuator and arranged to be operated by the actuator, for example to be movable. The conveyor is preferably a horizontal or substantially horizontal conveyor. The conveyor may be mounted horizontally or at least & partially horizontally, or substantially horizontally, for example under or in openings made in the lower part of the toilet units 0, such as the lower part. “Partially horizontal”> 35 - means that at least part of the conveyor is horizontal. “Substantially horizontal” may comprise a relatively small angle to the horizontal, such as 0-3? angle, 0-5 ° angle, or 0-10? angle, up to 0-15 ° angle. However, a large angle increases the amount of space required vertically. For example, the system may have a flat and / or low housing with openings for each seat, such as a 5-20 cm high housing, below the row of toilet seats. The width of the housing can be greater than its height. For example, the conveyor may be selected from a screw conveyor, a vibrating conveyor, a belt conveyor and a cola conveyor.

The screw conveyor has a helical spiral rotated by an actuator in the body, housing, tube or trough, which may be axial or non-axial and which, as it rotates, conveys material inside the body, housing, tube or trough. The screw conveyor is particularly suitable for transporting solid material and can be - implemented in a housing or pipe of relatively small diameter, which on the other hand can be very long. Stopping the screw conveyor prevents the toilet waste in it from advancing or leaving. An opening may be provided in the housing, pipe or the like of the screw conveyor for each fermentation unit for receiving toilet waste in the conveyor. One form of screw conveyor is - a spiral conveyor. The helical conveyor has a spiral in the (outer) tube, in which case the actual screw conveyor is formed by a spring spiral, and the outer tube can be, for example, a plastic tube. If necessary, the spiral conveyor can also be mounted at least partially on an arc. Its spiral and / or tube may be flexible. Spiral conveyors are lightweight and suitable for long transport distances, up to 13 meters. Fig. 2c shows a spiral conveyor 14 mounted in a housing 42 in the opening 41 below the toilet seat 10, into which the toilet waste falls through the trough 40. The toilet seat 10 has a unit 43 in the seat for removing separated urine. The vibratory conveyor derives its transmission force from the vibration asymmetry. By vibrating, it is also possible to arrange the movable pieces in the desired position and density. The vibratory conveyor S may have a trough-like, trough-like, trough-shaped or planar N conveying portion, on which the toilet waste moves from the toilet units, and N moves forward from the vibration force. The vibrating conveyor enables the conveyor to be implemented in a N 30 low space, for example in a space arranged under the toilet units. This I saves space and allows the toilet system to be implemented at a level and = relatively low space. The transfer portion of the vibratory conveyor may be perforated, which & allows the material to be screened or the liquid to be separated from the solid 0 material. This can be especially useful if toilet seats are not> 35 - separating and urine, or other liquid material that has entered the toilet, is to be separated from other toilet waste. In this case, it may be possible to provide a chute, piping or the like under the vibrating conveyor for receiving and / or directing the separated urine elsewhere, for example to a collection tank, a treatment tank and / or for further processing.

In a belt conveyor, an annular belt rotates around at least two rollers, at least one of which is Pull. An actuator that moves the belt, such as a traction motor, may be inside the drive roller. The top of the belt either slides against a smooth surface or has free-rotating support rollers underneath. The belt can be guided to be trough-shaped at the edges so that toilet waste does not spill from the belt to the side. The belt conveyor can be vibrated to prevent the sticky material from sticking. Lifting conveyors may have obstacles at regular intervals on the conveyor belt to prevent the material from sliding backwards. A cola conveyor has a frame, housing, trough or tube, as in a screw conveyor, but the goods are carried by plates attached to a moving chain, i.e. cavities.

- Said conveyors make it possible to move the toilet waste in a horizontal or substantially horizontal direction or plane, which makes it possible to implement the toilet system in one plane and saves space. “Substantially horizontal” may comprise an angle of 1-20, 1-10 or 1-5 degrees with respect to the horizontal. The actuator using the conveyor can be controlled so that the conveyor starts only - if necessary and moves only the required amount. The signal to start the conveyor can be obtained from a sensor on the seat or another sensor in the toilet cubicle, for example an optical sensor such as an infrared sensor or a switch on the door, such as a locked switch or a sensor arranged to detect a door lock. The flow of toilet waste in the system can also be controlled and regulated for other reasons, for example, if a certain amount of toilet waste is desired to proceed to a certain stage at a certain time. This S can be implemented in the toilet system - by one or more control units adapted to control the system N and by one or more sensors connected to it / which detect the status of the system, and by one or more actuators connected to it / them N 30 - for example conveyor actuator I , which control unit (s) is / are arranged to control.

a & There may be one or two or more toilet waste conveyors. If there are two or more conveyors connected to the toilet units, the> 35 - toilet waste conveyed by them can be combined, for example by means of an additional conveyor, which may be of the same type or different from said conveyors collecting from the toilet units, which can be called first stage conveyors. The additional conveyor, which may be called a second stage conveyor, may be, for example, arranged perpendicularly to two or more conveyors at their ends, the second stage collecting and combining the toilet waste transported by the first stage conveyors and further transporting them to the next stage.

The second stage conveyor can also operate horizontally.

The next step may be a composter, or any pre-treatment step preceding it, which may include a separate tank, such as a processing tank.

At this stage, the system may still have a separate third stage conveyor, such as a horizontal conveyor, which transports the toilet waste from the second stage conveyor to the pre-treatment stage tank or composter.

A third stage conveyor may be necessary, for example, when implementing the system in confined spaces, for example - a container, in which case the subsequent stages may be separated from the toilet spaces behind the wall, in practice in the toilet waste processing department.

The third stage conveyor may be the same or different from the first and / or second stage conveyor.

It can operate horizontally, substantially horizontally, or even partially vertically, depending on the structure and needs of the system.

Further - there may be a need for a fourth stage conveyor that can operate at least partially vertically, such as an oblique conveyor.

This may be necessary in confined spaces, such as a container where one or more of the next stage tank or equipment is mounted on a higher level, for example a pre-treatment stage tank or composter.

The fourth stage conveyor may be the same or different from the previous stage conveyor.

It can raise toilet waste to a height of, for example, 1-3 m, such as 1.5-2.0 m, for example at an angle of about 45 degrees.

The system may further comprise a fifth stage conveyor which may operate horizontally and which is arranged to transfer the toilet waste from the fourth stage conveyor to the tank or composter of the processing stage.

In this case, the tank or composter may have an opening at its upper end, i.e. an inlet of the tank, which is arranged S to receive toilet waste from a conveyor, for example via a funnel.

In this case, the receiving container can operate by gravity and does not necessarily require separate conveyors within it.

Alternatively, a conveyor, such as a third, N30 to fourth or fifth stage conveyor, may be arranged to convey toilet waste to an opening in the side of the receiving tank which acts as an inlet to the tank. 30 In general, any second stage or subsequent stage conveyor in the system may operate horizontally, diagonally or vertically as required, or may be mounted in that direction or substantially in that direction.

Any of the conveyors may be arranged to separate the liquid in the toilet waste, for example through one or more holes in the bottom of the conveyor, or through a perforated part, as described above for the vibrating conveyor.

The separated liquid can be recovered by means of a collector, pipe or piping arranged to receive it, and led elsewhere, for example to a tank or further treatment, as described herein.

In particular — the conveyors between the toilet units and the composter are encapsulated.

The conveyor or conveyors are generally arranged to convey toilet waste in a material handling direction from the starting point or points to the end point, such as from one or more waste receiving units, such as a toilet unit, for waste treatment and exit of treated waste from the system.

A conveyor may not be required at all stages, as the waste may also pass from one stage to the next by gravity or some other mechanism, especially during and after the treatment of the waste.

The start point or points and the end point are usually located in different places, such as different spaces.

Preferably, the material - does not travel against the processing direction at any stage.

The toilet system comprises a composter with an inlet and an outlet, which inlet is connected in a sealed manner to at least one toilet waste conveyor, which may be one of said 1.-5. a stage conveyor, and which composter is arranged - to receive dry toilet waste from said at least one conveyor.

There may also be other parts of the system between the conveyor and the composter, for example a processing tank.

The composted material is arranged to exit or be removed from the outlet of the composter.

The composter comprises at least one tank, which may be thermally insulated.

The composter may have one or more mixers for mixing the material to be composted.

The composter may have one or more sensors, such as an electrical sensor, for detecting temperature, humidity, pH, amount of material to be composted, N gases or other substances.

The sensors may be connected to one N 30 or more control units or other data acquisition unit, which I wired or wireless.

The composter may have means for transferring the material to be composted to, from and / or from the composter, such as one or more mechanical members connected to the actuator, such as blades, screws, or similar conveyor solutions.

These can be functionally> 35 - connected to one or more control units.

For example, the composter may have means for removing liquid, solid and / or gas, such as an orifice, valve or the like, which may be operatively connected to one or more control units, the orifice, valve or the like being system controllable, allowing the system to control liquid, solid and / or removing gas or exiting the composter by opening and closing the device. The removal of liquid, solid and / or gas can also be effected by one or more agitators in the composter or by one or more means for transferring material to, from and / or from the composter, which can, for example, compress and / or mix the material and facilitate liquid, solid and / or gas evolution. The composter may have means for treating the compost, such as one or more agitators, means for adding one or more substances, such as a liquid, for example a chemical, a dry substance, such as a desiccant and / or an accelerator, and / or means for controlling the temperature. One or more of said substances may be added to the composter to control composting, for example in response to one or more values measured from the system.

In one embodiment, the dry toilet system comprises, before the composter, a processing tank, which may be thermally insulated, having an inlet and an outlet, which outlet is sealed to the composter, and means for pretreating toilet waste, such as one or more mixers, means for treating one or more substances, , for the addition of a chemical, a desiccant and / or an accelerator, means for removing liquid, solid and / or gas, and / or means for controlling the temperature. The processing tank can also be called a preprocessing tank and the step performed therein as preprocessing. The inlet of the processing tank is sealedly connected to the conveyor of the previous stage, which may be one of the mentioned 1-5. phase conveyor. In this case, the inlet of the composter is sealed to at least one toilet waste conveyor via a processing tank. The processing tank may also have one or more sensors, such as N electrical sensors, for detecting the temperature, N humidity, pH, amount of material, gases or other substances in the toilet waste or compostable material. These sensors can also be connected to one or more control units I. The processing tank may have means for transferring toilet waste or compostable material to, from the tank, and / or from the tank, such as one or more mechanical members connected to the actuator, such as blades, screws, or similar conveyor solutions. These can also be functionally connected to> 35 - one or more control units. The processing tank can be above the composter, so that there is no separate conveyor between them. Alternatively, there may be a separate conveyor or other means or mechanism between them for transferring material, for example if they are adjacent.

The processing tank may be arranged to process the toilet waste to a desired shape, for example to a desired humidity percentage, temperature, composition, or pH. For example, the processing tank may include means for removing liquid, such as an orifice, valve, or the like, which may be operatively connected to one or more control units, wherein the orifice, valve, or the like is controllable by the system, allowing the system to control liquid or liquid from the processing tank. opening and closing the device. The separation and / or discharge of liquid can be effected by one or more agitators in the tank or by one or more means for transferring the material to be composted - into the tank, in the tank, and / or from the tank, which can, for example, compress and / or mix the material and facilitate liquid separation. Drainage may be necessary if the toilet waste contains an exceptionally large amount of liquid, such as urine, or if other liquid, such as water, has entered it. The toilet waste can also be mixed and / or incubated with the desired additives before the actual composting, such as with a compost stimulator or accelerator, a desiccant, or other substance. Additives can also be added or alternatively to the composter. The means for adding one or more substances, e.g. to a process tank or composter, may comprise an opening, valve or the like, e.g. above the process tank or composter, the opening, valve or the like being controllable by the system, allowing the system to control the addition by opening and closing instrument. The means may also comprise a container for the substance to be added from which the system can dispense the substance. The tank can be, for example, above the process tank or the composter, in which case the substance can drain from the opened opening, valve or the like by gravity. The means may also include a substance conveyor, S such as a screw, a pallet or the like, which is controllable by the system and by which N substances can be added in the desired amount, especially in the case of a solid. N The container of the substance to be added may have a lid or the like for closing the container from the outside N 30, in particular a sealed lid. The container for the substance to be added can also be separate from the process container or the composter, for example in a more serviceable condition, and can be connected to an opening, a valve or the like by a pipe or conveyor.

LO 00 2 35 - The means for adding liquid in the system may comprise a pipe or other valve supplied to the object from a tank or other source of liquid, together with a possible valve for controlling the dosing of the liquid, which valve may be manually or electrically operated. The electrically operated valve may comprise an actuator that controls the opening and closing of the valve and is connected to one or more control units. The dosing of the liquid can be automated so that in response to one or more values measured from the system, the control unit is arranged to dispense a predetermined or calculated amount of the desired liquid into the system, for example a processing tank or a composter. The means for adding dry matter in the system may comprise an openable and closable valve, flap or the like arranged to supply dry matter from a tank to a target, for example a dry matter tank above an object such as a processing tank or composter, or the means may comprise a conveyor such as a screw conveyor, arranged to provide dry matter from the tank to the target. The means for adding dry matter may comprise an actuator which controls the opening and closing of a valve, flap or the like, or - the operation of a conveyor and which is connected to one or more control units. Dry matter dosing can be automated such that in response to one or more values measured from the system, the control unit is arranged to dispense a predetermined or calculated amount of desired dry matter into the system, for example a processing tank or a composter.

In one embodiment, the dry toilet system comprises means for recovering heat and / or one or more substances from the composter and / or the processing tank. The substances to be recovered may be, for example, one or more liquids, solids and / or gases, such as water, one or more nutrients, one or more organic or inorganic substances, carbon dioxide, or microbes. For example, organic or inorganic compounds or fibers can be recovered to give S a material that can be used, for example, as its fertilizer. In general, N liquids can be recovered and sent for further processing.

SN 30 - The system may comprise one or more of the toilet unit, conveyor, I processing tank, composter, piping and / or other suitable part of the system - or one opening together to enable the functions described herein, for example one for adding or removing substances, one - 0 for, one for the actuator and / or its wiring, one for the pipe, or the like. The toilet system may further comprise a container for the final product, which may be sealed to the outlet of the composter. The final product tank may also contain sensors similar to the composter, for example one or more sensors for detecting temperature, humidity, pH, amount of composted material, gases or other substances in the composted material. These sensors can also be connected to one or more control units. The final product container may include means for transferring the composted material to, from, and / or from the container, such as one or more mechanical members connected to the actuator, such as blades, screws, or similar conveyor solutions. These can also be connected to one or more control units. There may be another conveyor between the composter and the final product container, which may be - for example a sixth stage conveyor, and which is arranged to convey the composted material from the composter to the final product container. This conveyor can also be similar or different from the conveyor of some previous stage. Preferably, all the conveyors of the system are encapsulated and the enclosures are sealed to each other or to said containers in order to keep the system closed.

The toilet system may comprise an outlet connection, such as a pipe, instead of a container for the final product, which may be connectable to a bag or similar collector to collect the final product. Correspondingly, the outlet connection may be emptied into another container, for example a pallet or the like. The outlet connection may have a flap or other closure that opens only when necessary, such as when the final product is removed from the system. The end product collector may be attached to the end of the outlet connection, such as a sack to the end of the pipe. The joints between the parts of the toilet system, in particular the joints for the transfer of toilet waste or the joints for the transfer of compostable or composted material, are sealed, for example substantially airtight and / or gas-tight, to reduce odor nuisance, For example, elastic seals such as rubber or silicone N 30 seals, sealant, sealing tape or the like can be used for sealing. The parts of the system are preferably shaped to fit together as closely as possible. According to one example =, the parts of the system are not detachable from each other, especially during operation &. co> 35 - In one embodiment of the system, the dry toilet system comprises means for creating a vacuum in the system, such as a vacuum pump. In one embodiment of the method, a vacuum is provided in the system. The vacuum may be arranged to be formed at least at or from the beginning of the system,

thereby preventing odors from rising from the toilet units to the toilet side itself.

The vacuum can be arranged to be formed, for example, in or from a composter, or in the direction of material flow after the composter, for example at least from toilet units to the composter, whereby the vacuum absorbs air through the composter / composter and provides active aeration of the compost.

The air intake to the system is preferably via toilet units, such as toilet seats, and if the toilet units are in separate booths, each booth, for example the roof, may have a separate air intake to provide replacement air.

The toilet cubicles therefore do not have to reach the ceiling of the toilet compartment.

The supply air pipe can be connected to the ceiling of the toilet cubicle, for example from the roof of the toilet compartment, in which case the air comes directly from the outside.

This will help reduce local odor nuisance.

The vacuum or its source can be arranged at a certain point in the system by providing a vacuum pump, or more specifically its suction opening at that point, for example after the compost has been discharged.

The vacuum pump may be arranged to pump the air it draws outside the toilet system through the outlet of the vacuum system, for example to the roof of a toilet system in a building or portable tank or to another place where it causes as little odor nuisance as possible.

Alternatively, instead of a vacuum pump, a fan / vacuum cleaner can be used, which is arranged to provide air flow in the system in the desired direction, such as the direction of material flow.

In general, aeration of the compost can be arranged actively or passively.

In passive aeration, the air flow is not enhanced, while in active aeration it is enhanced, for example by suction, for example by creating a vacuum, or by blowing air through the compost, for example mechanically as described above.

Active aeration can be divided into negative and positive S aeration.

In negative aeration, air is sucked through the compost, usually from the N surface through the compost, using a negative pressure, i.e. a vacuum.

In positive N aeration, air is blown through the compost.

In principle, both can be N 30 - used in the present system, depending on whether a device providing a vacuum I or a fan is used. a & The toilet system may include one or more sensors at one or more points in the system, which sensors are arranged to detect one> 35 or more of the following: user presence, surface level, temperature, humidity, carbon dioxide concentration, oxygen concentration, pH, air flow rate, fluid flow rate, material advance rate, amount of material, e.g., in a tank, concentration of a substance such as ammonia or urea, state of actuator connected to the actuator, such as rotational speed, and the like, which sensor (s) are connected, wired or wireless, to one or more to a device arranged to receive the detected information.

The sensor may also be an optical sensor or camera that can be used to monitor system operation at one or more points in the system described herein.

This device or one or more other devices are arranged to process the information and control the toilet system based on the information so as to achieve or maintain the desired system operation, e.g., optimal composting efficiency, desired temperature, desired final product composition, desired processing time, or the like. - These devices can be called one or more control units.

The control unit may have one or more units, such as separate devices, and is arranged to process information in a predetermined manner, such as programmed.

The control unit may have one or more processors, memory, user interface, display, keyboard or touch screen, power interface, one or more physical connectors and / or wireless communication means for connection to sensors and / or other external devices, such as a wired or wireless network connection.

The control unit may comprise one or more computers and / or an embedded system.

The control unit may have software arranged to perform one or more control operations, such as controlling and operating one or more devices connected to the control unit.

Actuators connected to the system may be operatively connected to one or more control units, which means that the control unit can operate the actuators.

The control unit may be connected to one or more actuators or other devices that function to affect the state and / or operation of the system, such as pumps, fans, valves, flaps, mixers, conveyors, heaters, coolers, and the like.

The actuator may comprise, for example, one or more electric motors, such as a rotary or linear electric motor, a servomotor, a solenoid, a hydraulic or pneumatic motor, or a cylinder, or combinations thereof.

N Preferably, the actuator is electrically and / or electrically controllable.

The actuator connected to the actuator N 30 can cause a mechanical movement, for example by operating a valve I or mixing, or by heating, for example.

The actuator can affect the operating + quantity of the process, such as temperature or the flow of liquid, gas, electricity or other. 3 0 By controlling the operation of these devices, it is possible to achieve or maintain the desired operation of the> 35 system, for example by means of the measures described here.

The desired action may be to achieve and / or maintain a predetermined value, for example to keep a certain value within reference values, such as temperature,

moisture content, pH, dry matter content, specific substance content or the like. The control unit with its connected sensors and devices forms a control system, which may be implemented in the physical spaces of the toilet system, for example in a mobile container. The control system includes the necessary wiring between the various devices and / or the necessary wireless network equipment to establish connections between the devices, as well as any other switches, control devices, actuators, connectors, adapters, converters, and the like required by the system to operate. In general, any device in the toilet system whose operation can be controlled or monitored can be connected to the control system and arranged to be controlled and / or monitored. The control system may be remotely connected to an external system or user, for example wirelessly, allowing remote monitoring of the system, obtaining information about it, such as activity reports, and possibly affecting the operation of the system. The information collected can be made into a written document for authorities, for example. Primarily, however, the system is designed to operate as independently and automatically as possible, so that it does not necessarily require external action.

Also shown herein is a portable transport container comprising any of the closed dry toilet systems described herein. The movable container may be any suitable freight container that can be moved by or from one means of transport without reloading the contents. It can be a container, such as a container used for road, rail, air or sea transport. The transport container, the container, may be made of metal, for example steel or aluminum, or of a composite material, plastic, wood or other suitable material. The most common N Container type is an ISO container defined by the International Organization for Standardization (ISO) and classified by S. It is the most widely used and mass-produced N 30 - due to its cheap transport unit. = = The toilet system presented here is particularly well suited for container construction. Since no separate drainage or other vertically space-consuming piping is required, the toilet system can be built on one level and fitted into a container. > 35 - Containers can be made available and transported to the destination in the desired number to cover the required toilet capacity. Once the container is on site, the toilet is ready for use without any construction work or the like. Drainage is not required, as substantially clean water is discharged from the system into the hygienized toilet waste. The capacity of the container-fitted dry toilet system is large. If necessary, the container can be connected to an external power supply to supply power to the system's equipment and, for example, lighting, but the system can also be self-sufficient in electricity, for example it can - comprise a battery system which can be pre-charged and / or charged with solar, wind and / or by thermal energy from the system. In this case, the system may have one or more solar panels, a wind power plant or a generator powered by thermal energy or the like, respectively.

- There is provided a method of treating toilet waste, the method comprising - providing a closed dry toilet system or a portable transport container as described herein, - composting the toilet waste accumulated in the composter for a time sufficient to hygienize the toilet waste to obtain treated toilet waste.

The method for treating toilet waste yields treated toilet waste which has been hygienized. The treated toilet waste meets the standards EC 1069/2009 and 142/2011. In one embodiment, the hygienized toilet waste is transferred to a container for the final product. The method can be performed as a batch process or continuously.

- More preferably, the method is continuous. This reduces or eliminates the need to perform maintenance, draining, or other operations on the system during operation, which could impair hygiene, system operation, and / or cause downtime. However, it is necessary to carry out such measures from time to time. For example, the composter may require a feed break of about 24 hours about once a week, at the end of which is - sanitizing.

S The dry toilet system or a transport container containing it is provided at a desired location, as described herein. The system is built, for example, in a suitable space in the building, or the spaces are built separately, for example walls, N 30 ceiling and / or floor. Alternatively, one or more transport containers are brought into place and I is placed in a suitable place, for example on level ground or on another suitable surface. If the system needs external power, it will be connected to one. & The system control electronics are switched on if necessary and the system is 0 ready for operation. Toilet system users produce toilet waste, which the system transfers to the composter for composting through possible pre-treatment. Toilet waste is composted in a composter at a temperature above, for example, 40 ° C. In one embodiment, more than 50 toilet waste is composted in the composter

* C temperature, or above 55 * C temperature. In a particular embodiment, the toilet waste is composted in a composter at a temperature above 60 ° C, even above 62 ° C or above 65 ° C, thus ensuring the elimination of pathogenic microbes in particular. In many cases, even a lower temperature is sufficient, as mentioned above 50 ° C or above 55 ° C. Most common pathogens die relatively quickly at temperatures of 50-60 ° C, even in minutes or hours. If it is desired to use high temperatures, it may be necessary to ensure that the composting process itself operates at said temperature. Many conventional composting microbes can be inactivated at high temperatures, such as compost in general - mesophilic microbes, in which case it may be necessary to add one or more different thermophilic microbes to the system. By thermophilic microbe is meant a microbe that is viable and / or retains at least a portion of its activity, such as composting activity, at a desired temperature, for example, 40-70 ° C. Thermophilic microbes can be supplied as a separate compost accelerator, which may also contain other ingredients. In the tests, it was generally found that the internal temperature of the composter was between 40-55 ° C and when hygienized above 70 ° C for two hours. In one embodiment of the method, one or more substances, such as a liquid, for example water or urine, or a dry substance, such as a desiccant, and / or a compost starter or accelerator, for example a processing tank or a composter, are added to the toilet waste. In one embodiment of the method, a thermophilic accelerator is added to the toilet waste, for example in a processing tank or composter. The addition can be carried out automatically, whereby - the control unit controls an actuator which causes the addition of accelerator to a desired point in the system, such as a processing tank, one or more of said conveyors, or a composter connected to the actuator, e.g.

S N 30 - Achieving the desired temperature is influenced by several factors, such as the microbial strain I used, the composition of the material to be composted, the moisture content of the compost and the like. In general, an efficient composting process itself produces the required temperature. The temperature of the compost can generally be in the range of about 30-70 ° C or <about 40-70 ° C. However, if it is desired to increase the efficiency of composting and to achieve efficient hygienization of the final product, it may be possible to keep the temperature of the compost in the range of 50-70 ° C, 55-70 ° C, 60-70 ° C, 62-70 ° C or 65-70 ° C. One or more of the measures mentioned herein may be used to maintain the temperature of the compost in the above range.

Sufficient time for sanitation may depend on conditions, starting materials, substances to be added and other variables.

A sufficient time may be, for example, 2-34 hours when a thermophilic microbial strain is used.

For compost to work well, it must have the right ratio of carbon, oxygen, nitrogen and water.

Composting is effective when the carbon: nitrogen ratio is in the range of 10: 1 to 20: 1. The material to be composted contains toilet waste, but since the composting process requires aerobic conditions, it may also be necessary to add litter or the like to ensure air circulation throughout the compostable material, especially if the material contains a lot of moisture.

The vacuum sucked into the system provides active aeration, which helps maintain aerobic conditions, and the vacuum can also be controlled to achieve and / or maintain the desired level of aeration to control the composting process.

Mechanical agitation in the composter, for example rotating blades, can also be used for air conditioning or to aid it.

Anaerobic conditions should be avoided, as under anaerobic conditions digestion reactions are the main reactions.

These, in turn, cause odor nuisances and methane emissions, for example.

It is usually not necessary to add water to the compost, as water and heat are released from the material to be composted during the decomposition process.

Most of the water is released as steam and oxygen is used quickly in the process.

However, the amount of water vapor released from the biomass is high, so there may be a need to control and regulate the process.

The ratio of water to air is of great importance to the temperature of the compost, so if it is desired to maintain a high temperature, there may be a need to optimize these variables.

Sometimes it may be necessary to adjust the moisture in the compost by adding a liquid such as condensate or other water.

In particular, sanitation may require a sufficient moisture content to start S.

It is also possible to pass at least part of the urine and / or other liquid accumulating in the toilet system to the compost, in which case it can also be composted, or the properties and performance of the compost and the composting process can be affected.

By adding liquid, I can also influence the temperature, for example by raising or lowering it depending on the temperature of the liquid =.

For example, lowering the temperature of compost with liquid may be a better option than with air, as the liquid does not contain free oxygen, which would speed up the composting process and further raise the temperature.

The moisture content of the compost or> 35 pretreatment can also be affected by the addition of a dry matter, such as a dry matter.

The temperature of the compost can also be controlled by means of air, for example directly by means of air temperature, whereby by blowing or sucking in or through the compost, warm or cold air can be used to heat or cool the compost, respectively. Air flow can also be used indirectly to control the temperature, as higher air flow enhances composting and causes heat to rise, and correspondingly, reducing air flow can slow down the process and lower the temperature. The air flow can be adjusted by adjusting the vacuum pump or other air pump or fan in the system. These devices may be connected to one or more control units, wherein in response to one or more values measured from the system, the control unit is arranged to control the operation of the air flow device, for example to switch it on or off, or to adjust its speed. The composter may also have one or more heaters or coolers, which may be used to control the temperature, respectively, and which may be connected to one or more control units, the control unit being arranged to control the heater or cooler to the desired temperature in response to one or more measured values. in compost. Similar arrangements can be applied in the same way to the processing tank.

- The liquid to be added may be water, urine, or conveyor wash, or an equivalent aqueous liquid. The desiccant may comprise a plant-based material, such as a wood-based material. The desiccant may be provided, for example, in the form of pellets, chips, shell or the like. Of these, the necessary amount can be added to obtain the desired ratio between the material to be composted and the litter.

- Dry matter can also be added to control the moisture content of the compost, in which case it is added to achieve the desired moisture content or dry matter content. The desiccant can also reduce odor nuisance, bind nitrogen and / or phosphorus, and N can accelerate compost, so it can also be added to provide these properties N.

N 30 I In one embodiment of the method, the separated urine is treated to separate the substances therein, for example dissolved or suspended, in practice from water. The separated substances can be recovered and / or discharged elsewhere, for example to the final product tank. Urine can be treated, for example, by precipitating at least some of the> 35 solutes, for example by adding one or more precipitants or by controlling the temperature. Substances in the urine, such as precipitated and / or suspended substances, can be separated, for example, by filtration. Urine can also be recycled through a cooling system or heating system. Such an

The system may be a separate device, which may be electrically operated. The urine can also be heated by passing it through a composter, for example through one or more pipes in the composter, whereby the relatively high temperature of the compost is sufficient to heat the urine. Other liquids can also be heated in the same principle, for example water, such as toilet wash water. In one example, the compressor thus comprises one or more heat-conducting pipes and / or heat exchangers connected to the piping through which the external liquid is arranged to pass. In this case, separate heaters are not needed to heat the liquids, and energy is saved. The liquid can be recycled on the same principle - through the composter and used to heat the toilets. The fluid circuits required in the system may be provided by one or more pumps, such as a circulating water pump, which may be electrically operated. One or more pumps may be connected to one or more control units arranged to control the pumps, for example in response to one or more values measured from the system and / or pre-programmed operation. In one embodiment of the method, heat and / or one or more substances, such as one or more organic or inorganic compounds, are recovered from the composter. The heat can be recovered from the composter as described above, or it can be recovered from another point in the system, such as the processing tank or the air flowing in the system. The heat can be recovered by a heat exchanger and transferred to the liquid, or it can be recovered as warm or heated air. For example, the resulting liquid can be - used to heat some part of the system or air. The heat can be used to heat the toilets, for example by blowing heated air, or S by circulating the heated water through one or more heat exchangers, such as N radiators.

S N 30 The substances to be recovered can be, for example, organic or inorganic compounds containing phosphorus, nitrogen and / or potassium I, such as various compounds of nitrogen, phosphorus or potassium. 3 <In one embodiment of the method> 35 - one or more properties of the system, such as temperature, pH, carbon dioxide content and / or moisture content, are observed at one or more points in the system, and

in response to the properties observed, at least one point in the system is subjected to measures that affect the system temperature, pH, temperature and / or humidity of the material to be composted, the rate of toilet waste in the system, and / or liquid or dry matter dosing.

The action may affect the detected feature and / or Other feature.

Examples In one example (Figures 1a and 1b), a closed dry toilet system is - implemented in a BM30 container 30 with external dimensions of 9.120 m x 2.435 m x 2.591 m.

The container is divided into a toilet compartment 3) and a toilet waste processing compartment 34, which are separated from each other by a wall.

The toilet compartment is further divided into two parts, men's 35 and women's 36 toilets, which are separated by a wall.

The women's section has five dry toilet seats 10 and the men's section has three dry toilet seats 10 and three urinals 12. The toilet seats are each in their own door-to-door booth with a roof air intake connected by pipes to the air intake in the middle of the container roof and the urinals separated .

Each compartment has a hand basin 11, 13 to which water can be introduced from a water tank on the roof.

Dry toilet seats are provided on top of the first two stages of conveyors 14a, 14b, which conveyors are arranged to start when a dry toilet seat connected to them is used.

The conveyors 14a and 14b are 9 and 2 m long spiral conveyors with a diameter of 125 mm and are housed in 200 x 200 mm U-shaped housings sealed to the seats 10, as schematically shown in Figure 2c.

The toilet waste from the first stage conveyors 14a, 14b travels 3 meters long to the second stage conveyor 15, which is perpendicular to the first stage conveyor S.

From the second stage conveyor 15, the waste is transferred behind the wall to the N toilet waste processing compartment 34. The processing compartment has an S Green Good quick composter 20 placed on the floor, a final product tank 22 and a N 30 - pre-processing tank 18 placed on top of the composter. by means of a conveyor 16 (horizontal advance approx. 1.5 = meters) and a horizontal conveyor 17 (approx. 1.5 meters). 3 <The waste is transferred to the preprocessing tank 18 through an opening above it and a funnel.

From the pre-processing tank 18, the waste is transferred by gravity to the composter 20 below. Composted toilet waste from the composter 20 is transferred to the storage vessel 22 next to the openable rear wall doors 36, 38 of the container 30 by means of a 1 meter discharge conveyor 19. The outlets of the hand basins of the men's toilet compartment 35 and the women's toilet compartment 36 are connected to a pipe 23, and the outlets of the men's washbasin 11 are connected to a second pipe 25, respectively. The pipes pass to a processing compartment 34 where they connect and lead to to suit each type of waste. Composting process The actual composting took place in an automated Green Good quick composter. The conditions of the composter have been optimized, so that the natural composting process was achieved in about 24 hours. Finally, the pulp was sanitized in accordance with the EU standard EC 1069/2009. The composting involved microbes that could be isolated from the soil and whose disintegration properties were maximized by appropriate temperature and mechanical aeration carried out on rotating pallets. The progress of the composting process could be monitored with the help of measuring devices installed in the composter, in which case e.g. temperature, pH, carbon dioxide content and / or humidity content. The measured variables were used to know how the process - progresses and whether it reaches, for example, a sufficient hygienisation temperature and time. S Composter emptying is automated. The composting trays or alternatively the N screw push the generated hygienized pulp from the discharge hatch into the N container of the final product or alternatively directly into the big bags or pallet. At no N 30 stage can the mass flow in the wrong direction in the process, because the mechanism responsible for transport I operates in only one direction and physically the start and end points of the process are located in different spaces. 3 co
