Definitions

  • the present invention relates to a rest station device for composting feces and urine.
  • Handling of human waste in the form of urine and feces is a growing problem worldwide, which is linked to sanitary risks as many areas lack the necessary facilities for an efficient and safe disposal thereof. For instance, many areas lack sewage treatment facilities or even a functioning sewage system. Also for boats this is a growing problem. Thus, often human waste materials risk being disposed of in an uncontrolled manner leading to a sanitary problem and a health risk for the people living in the area. Taking care of feces and urine may pose a problem also in other situations, for instance whenever a temporary rest facility is needed, e.g. on a construction site or during an intense tourist season in more or less remote areas where a proper sewage system is not available and water supply is restricted.
  • Known temporary rest facilities normally consist of a toilet positioned over a single, sealed vessel wherein urine and feces are collected until the vessel needs to be emptied.
  • Such conventional temporary rest facilities are very space demanding and are hard to move around as well as they are unpleasant to empty.
  • W09218442 A known portable system for treating human waste is disclosed in W09218442, wherein a transportable rest station is described where feces and urine are treated to be composted.
  • a transportable rest station is described where feces and urine are treated to be composted.
  • the composting rate of the system in W09218442 is unsatisfactory, and thereby a new more efficient system is desired.
  • the objects of the invention are essentially achieved by means of a toilet device for composting feces and for treating urine according to claim 1.
  • the system according to the invention is a better alternative than flush toilets, sewers and sewage treatment.

It is to be understood that the invention is not restricted in any way to the dimensions of the components seen in Fig. 2, and that the Figure is to be seen as illustrating the mere principle of the function of the system.
  • the composting toilet according to the invention uses aerobic decomposition to efficiently break down both urine and feces into stable compounds within the feces compartment unit 7. According to the invention urine is separated from feces ensuring that feces remain in an aerobic environment. Organisms rapidly break down feces into a compost material that has chemical, biological and aesthetic characteristics similar to topsoil and reduces its volume by over 90%. Consequently, there is no need for frequent removal of solid waste.
  • a liquid drain outlet 71 through which urine is transferred out of the feces compartment 7 to separate urine from feces.
  • the liquid drain outlet 71 is provided with a filter (not shown) which allows for passage of liquid.
  • the liquid drain outlet 71 leads to a liquid compartment 8 positioned underneath said feces compartment 7.
  • the lower base surface 70 of the feces compartment 7 is sloped (preferably at an angle between 2-7°, preferably 5°) creating a declination in a direction towards the liquid drain outlet 71 to promote efficient transfer of liquid by means of gravity out of the feces compartment 7 and into the liquid compartment 8.
  • Feces air outlet is achieved by means of an air vent 18 and a fan, in the form of a tube having its lower end disposed somewhere within the feces compartment 7. It is to be understood that said air outlet is not limited to the exact position shown in Fig. 2, but can vary somewhat.
  • Air vent 18 is of sufficient size and shape to enable sufficient ventilation of feces compartment 7 to compost feces in feces bed inside the compartment 7.
  • Air vent 18 may include an air vent outlet device 19 above roof 12.
  • Air vent 18 allows ventilation of air from feces bed and liquid compartment.
  • the feces retained in the feces compartment 7 is arranged to compost therein whereby a decomposed organic waste is formed.
  • Compost means decomposition of feces, to form decomposed organic waste which is suitable for sterilization and subsequent use as fertilizer or mixture with soil to form topsoil. Once initiated, composting of solid waste in feces bed building up inside the feces compartment 7 is continuous during exposure of feces bed to conditions sufficient to maintain composting of feces. Composting can be initiated spontaneously or can be initiated by combination of feces collected within feces retainer with a suitable filler, such as wood chips, to allow sufficient aeration and drainage of feces bed to cause composting.
  • the bacteria content of feces bed is reduced in feces compartment 7 by about ninety-five percent before removal from feces bed.
  • the composting of solid waste is further supported by means of introducing colonies of micro organisms, which feed on the solid waste, into the compartment 7.
  • Suitable additive include "biobacteria fragrance” which comprises a combination of micro organisms, enzymes and biologically degradable fragrances.
  • Other additional micro organisms which may be introduced into the feces bed are black soldier fly larvae and the worm "Eisenia Foetida".
  • the different micro organisms may be introduced in combination or separately into the feces bed.
  • the micro organisms may be re-filled into the feces bed whenever needed. Thanks to the presence of micro organisms the composting rate may be increased.
  • the active composition is in the form of a stable liquid and/or dry powder product that contains specifically developed bacteria spores, i.e. a formulation that is free of pathogenic bacteria. Further it does not preferably contain any carcinogenic or hazardous compounds and is non-corrosive.
  • the density may be about 1190 kg/m3, containing spores of Class-I (American Type Culture Collection Classification and Swedish Workers Protection Agency AFS1988: 12) microorganisms of the Bacillus family.
  • the pH will be about 7.0 to 7.5.
  • the stability thereof in room temperature ( ⁇ 25oC) is a minimum 2 years and if refrigerated (3-5oC), minimum 3 years.
  • Liquid waste consists mainly of composted urine and possibly some water, so-called "compost tea", nutritious and practically free from bacteria and odor.
  • the compost tea is stable and can be stored for a considerable time in said liquid compartment 8 and/or in connected storage spaces.
  • bacterial action causes a chemical transformation that converts the chemically unstable components of urine (urea and ammonia) into a liquid end-product containing nitrite and nitrate.
  • This liquid is biologically and chemically stable and contains nutrients valuable for fertilizer for different kinds of vegetation.
  • Nitrification bed is disposed within waste compartment 7 and is sufficiently dense to prevent uneven distribution or channeling of urine throughout nitrification bed.
  • Nitrification bed may include a substrate which can support aerobic nitrifying bacteria and which is relatively stable. Also, suitable substrates can maintain a sufficient moisture content and allow sufficient aeration to support aerobic nitrifying bacteria for nitrifying a significant portion of ammonium ions in the urine collected in urine retainer. Examples of suitable substrates include loam, wood shavings and other cellulosic materials, etc. In a preferred embodiment, nitrification bed comprises peat moss. The amount of aerobic nitrifying bacteria supported by the substrate in nitrification bed is sufficient to nitrify a significant portion of ammonium ions in urine collected under expected use-conditions of rest station 1.
  • Nitrification of the ammonium ions causes the ammonium ions to form, for example, nitrites and nitrates.
  • Aerobic nitrifying bacteria can be introduced to nitrification bed by indigenous bacterial growth or by artificially introducing aerobic nitrifying bacteria into nitrification bed. Examples of suitable aerobic nitrifying bacteria include nitrobacter, Nitrosomonas, etc.
  • the toilet device may comprise an arrangement for dry flushing the solid waste by flattening it with a special built-in mechanical device.
  • Fig. 4 presents a flow chart representing an overview of the sustainable rest station technology according to the invention.
  • the rest station is arranged with water for hygiene purposes (e.g.
  • a water supply system is a closed loop system A as is schematically described in the flow chart of Fig. 4.
  • a fresh water tank and a separate grey water tank are connected to each other via water conduit means comprising a purification unit.
  • fresh water can be supplied to the fresh water tank to be used for water supply to a hand bidet or to a hand wash basin.
  • the grey water produced from the washing station can be transferred to the grey water tank by means of gravity and from the grey water tank through the conduit means back to the fresh water tank via the purification unit.
  • the water can be treated and purified in said purification unit using an ecological purification technology known in the art. For instance such water treatment may include mechanical purification for removing particles and microorganisms and/or disinfection in UV filter. Having passed the purification unit the water is then transported (e.g. pumped) back to the fresh water tank, which preferably is located above the grey water tank in order to use the power of gravity to supply water to the hand bidet and hand wash basin.

Abstract

La présente invention concerne un dispositif de toilette permettant de composter les matières fécales et de traiter l'urine, comprenant un compartiment à matières fécales avec un siège de toilette (6) et un réservoir à liquide situé en dessous dudit compartiment à matières fécales, un passage pour le liquide permettant au liquide d'être évacué du compartiment à matières fécales vers l'intérieur du compartiment à liquide, et un passage d'évacuation vers le compartiment de compostage afin d'exposer le lit de matières fécales à l'intérieur du compartiment de compostage à suffisamment d'air pour permettre le compostage des matières fécales, formant ainsi un produit de compostage. L'objectif de cette invention est de présenter un cabinet de toilette qui représente une amélioration par rapport aux dispositifs précédents, dans le sens où la personne utilisant le cabinet de toilette ne peut pas voir le compartiment à matières fécales sous le siège de toilette. Cela est obtenu par la réalisation d'une partie de siège mobile (6A), qui est reliée à un mécanisme de couvercle (100) qui est placé sous le siège. Le mécanisme de couvercle dispose d'une unité de transmission, qui est disposée de manière à retirer un couvercle interne (101, 102) lors de l'activation.
