Description

Oppfinnelsen vedrører et rotsoneanlegg for rensing av urent vann, som omfatter en avgrenset masse av et vekstsubstrat beplantet med sumpplanter, som f.eks. takrør (Phragmetis communis), siv (Schoenoplectus lacustris) og dun-kjevle (Typha), bestanddeler for tilførsel av urent vann til substratmassen og bestanddeler for bortføring av renset vann. The invention relates to a root zone system for purifying impure water, which comprises a defined mass of a growth substrate planted with swamp plants, such as e.g. roof pipes (Phragmetis communis), reeds (Schoenoplectus lacustris) and down-roller (Typha), components for the supply of impure water to the substrate mass and components for the removal of purified water.

Slike rotsoneanlegg for spillvannrensing har i de senere år vunnet betydelig utbredelse. Such root zone plants for waste water treatment have gained considerable popularity in recent years.

En vannrensing som oppnås med et rotsoneanlegg, er basert på et komplisert samspill mellom substratmassen, sumpplantenes rotsystem og mikrofloraen i substrat- A water purification achieved with a root zone system is based on a complicated interaction between the substrate mass, the root system of the swamp plants and the microflora in the substrate

massen. the mass.

Mikrofloraen består delvis av aerobe bakterier og delvis av fakultativt anaerobe og obligat anaerobe bakterier. De aerobe bakteriers evne til å omsette de organiske stoffer som tilføres med spillvannet, er betinget av den oksygentil-førsel som skjer gjennom sumpplantenes intercellulære luft-forsyningssystem (aerenchym) som fører luft til vekstdelene under vannoverflaten. The microflora consists partly of aerobic bacteria and partly of facultative anaerobic and obligate anaerobic bacteria. The aerobic bacteria's ability to convert the organic substances supplied with the waste water is conditioned by the supply of oxygen that occurs through the swamp plants' intercellular air supply system (aerenchyma) which carries air to the growth parts below the water surface.

I de ovenfor nevnte samspill inngår også substratmassen som delvis virker som substrat for plantenes rotsystem og delvis som leverandør av forskjellige næringssalter for planter og mikroorganismer. The above-mentioned interactions also include the substrate mass, which partly acts as a substrate for the plants' root system and partly as a supplier of various nutrient salts for plants and microorganisms.

En ulempe ved de kjente rotsoneanlegg er at det går en betydelig tid, f.eks. opp til to år, fra det tidspunkt da plantingen finner sted og til det tidspunkt da anlegget er fullt funksjonsdyktig. Dette skyldes at plantene må ha lang tid for å utvikle et forgrenet rotsystem som er en forut-setning for anleggets effektivitet. A disadvantage of the known root zone systems is that a considerable amount of time elapses, e.g. up to two years, from the time when the planting takes place until the time when the plant is fully functional. This is because the plants must have a long time to develop a branched root system, which is a prerequisite for the plant's efficiency.

Denne ulempe fjernes ved hjelp av rotsoneanlegget ifølge oppfinnelsen som skiller seg fra tidligere kjente rotsoneanlegg ved at substratmassen er plassert i en oventil åpen og eventuelt tildekket flyttbar tank. This drawback is removed with the help of the root zone system according to the invention, which differs from previously known root zone systems in that the substrate mass is placed in a moveable tank that is open to the ceiling and possibly covered.

Ved bruk av en slik tank kan oppbygningen av et rotsoneanlegg påbegynnes på et slikt tidspunkt at anlegget er fullt funksjonsdyktig når det skal leveres. I praksis kan dette skje ved at det foretas beplantning i et antall tanker med substratmasse som tilsvarer det forventede salg 2-3 år fremover i tiden. By using such a tank, the construction of a root zone system can begin at such a time that the system is fully functional when it is to be delivered. In practice, this can be done by planting in a number of tanks with substrate mass that corresponds to the expected sales 2-3 years in the future.

Tanken er fortrinnsvis en formstoffkasse eller en metall- eller trekasse, f.eks. av vannfast kryssfinér, som er kledd innvendig med en vanntett plastfolie, f.eks. med en tykkelse på ca. 2 mm. Tanken, som fortrinnsvis er rektangulær og f.eks. har en lengde på ca. 6 m og en bredde på 2,4 m, er fortrinnsvis fylt med en substratmasse, som f.eks. jord, opptil en høyde på 60-80 cm. The tank is preferably a plastic box or a metal or wooden box, e.g. of waterproof plywood, which is lined inside with a waterproof plastic film, e.g. with a thickness of approx. 2 mm. The tank, which is preferably rectangular and e.g. has a length of approx. 6 m and a width of 2.4 m, is preferably filled with a substrate mass, such as soil, up to a height of 60-80 cm.

Den rektangulære tank inneholder fortrinnsvis i sin The rectangular tank preferably contains in its

ene ende en fylling av et partikkelformet, uorganisk materiale, som f.eks. kalksten, marmorstykker og singel, og har i sin motsatte ende en annen fylling av et partikkelf ormet, uorganisk materiale. I sistnevnte er fortrinnsvis lagt ned et dreneringsrør for bort-føring av det rensede spillvann. I stedet for å plassere fyllinger i endene av tanken, kan det her være utformet åpne kanaler som er avgrenset i forhold til substratmassen ved hjelp av vanngjennomtrengelige skillevegger som f.eks. kan være en perforert plastfolie eller et vevd tøystykke. one end a filling of a particulate, inorganic material, such as e.g. limestone, pieces of marble and shingle, and has at its opposite end another filling of a particulate, inorganic material. In the latter, a drainage pipe is preferably laid for the removal of the purified waste water. Instead of placing fillings at the ends of the tank, open channels can be designed here that are delimited in relation to the substrate mass by means of water-permeable partitions such as e.g. can be a perforated plastic film or a piece of woven cloth.

Det kan alt etter behov anvendes større og mindre tanker, og tankene kan være forsynt med slike sammenkoplings-deler at de kan sammenkoples parallelt. Larger and smaller tanks can be used as needed, and the tanks can be equipped with such connecting parts that they can be connected in parallel.

Ved levering av et anlegg ifølge oppfinnelsen tran-sporteres tanken eller tankene ut til bruksstedet og plasseres der oppå jorden eller i spesielt utformede, eventuelt støpte huller i denne. When delivering a plant according to the invention, the tank or tanks are transported out to the place of use and placed there on top of the ground or in specially designed, possibly cast holes in it.

En særlig fordel ved rotsoneanlegget ifølge oppfinnelsen er at det er miljøvennlig, ettersom risikoen for utsiving av urent vann og forurensning av den omgivende jord er helt fjernet. A particular advantage of the root zone plant according to the invention is that it is environmentally friendly, as the risk of leakage of impure water and contamination of the surrounding soil is completely removed.

Videre kan anlegget lett skiftes ut dersom det av en eller annen grunn skulle miste sin funksjonsdyktighet. Furthermore, the system can be easily replaced should it lose its functionality for one reason or another.

Endelig står man ved bruk av et anlegg ifølge oppfinnelsen fritt med hensyn til anleggets plassering, ettersom det f.eks. ikke behøves å tas hensyn til særlige jordbunns-forhold. Finally, when using a facility according to the invention, one is free with regard to the location of the facility, as it e.g. special soil conditions do not need to be taken into account.

Av sikkerhetsmessige grunner er det til den øverste For security reasons, it is for the top

del av tanken fortrinnsvis festet et stakitt. part of the tank preferably attached a fence.

Det beskrevne anlegg er især anvendelig til rensing av spillvann. Det skal imidlertid forstås at det også kan brukes til rensing av andre slags urent vann, f.eks. vann med et uønsket stort innhold av salter. Det har således vist seg egnet til å redusere inneholdet av hårdhetsfremkallende salter og andre salter, som f.eks. nitrater, fosfater og tung-metallsalter i grunnvann. The plant described is particularly applicable to the purification of waste water. However, it should be understood that it can also be used to purify other types of impure water, e.g. water with an undesirable high content of salts. It has thus proved suitable for reducing the content of hardness-causing salts and other salts, such as e.g. nitrates, phosphates and heavy metal salts in groundwater.

Også vann som inneholder uønsket store mengder organisk materialer, vil kunne renses i anlegget. Oppfinnelsen skal heretter beskrives nærmere under henvisning til tegningen, hvor Water that contains undesirably large amounts of organic materials will also be able to be cleaned in the plant. The invention will now be described in more detail with reference to the drawing, where

fig. 1 viser et rotsoneanlegg ifølge oppfinnelsen sett ovenfra, fig. 1 shows a root zone system according to the invention seen from above,

fig. 2 viser et loddrett snitt etter linjen II-II gjennom rotsoneanlegget som er vist i fig. 1. fig. 2 shows a vertical section along the line II-II through the root zone plant shown in fig. 1.

På tegningen angir 1 en rektangulær kasse hvor den innvendige side er kledd med en vanntett plastfolie. I kassen 1 befinner det seg en jordmasse 3, som er beplantet med sumpplanter (Phragmetis communis). I høyre ende av kassen 1 er det plassert en fylling 5 av et inaktivt materiale som f.eks. singel, og en tilsvarende, men smalere fylling 6, er plassert i venstre ende av kassen 1. Sistnevnte fylling er plassert over et dreneringsrør 7. In the drawing, 1 indicates a rectangular box, the inside of which is covered with a waterproof plastic film. In the box 1 there is a soil mass 3, which is planted with swamp plants (Phragmetis communis). At the right end of the box 1, a filling 5 of an inactive material such as e.g. single, and a corresponding, but narrower filling 6, is placed at the left end of the box 1. The latter filling is placed above a drainage pipe 7.

Det viste apparat omfatter videre et rekkverk 8 som omslutter den øverste del av kassen 1. The device shown further comprises a railing 8 which encloses the upper part of the box 1.

Ved bruk av anlegget ifølge oppfinnelsen innføres urent vann, f.eks. spillvann, i fyllingen 5, hvorfra det trenger inn i jordmassen 3 og beveger seg i retning mot fyllingen 6 og det dreneringsrør 7 som er plassert der. When using the plant according to the invention, impure water is introduced, e.g. waste water, in the embankment 5, from where it penetrates into the soil mass 3 and moves in the direction of the embankment 6 and the drainage pipe 7 which is placed there.

Under passeringen gjennom jordmassen 3 renses spillvannet i et slikt omfang at det rensede spillvann gjennom dreneringsrøret 7 kan tilføres naturlige resipienter eller brukes som friskt vann uten ytterligere rensing. During the passage through the soil mass 3, the waste water is purified to such an extent that the purified waste water can be fed through the drainage pipe 7 to natural recipients or used as fresh water without further purification.
